The essential information and innovations
The new EQE1: the main points at a glance
The executive sedan EQE is the second model to be based on the premium-class electric architecture (EVA2), following the luxury EQS sedan. The EQE will celebrate its world premiere at the IAA show (September/Munich). The staggered global launch will begin mid-2022. Production will be in Bremen for the world market and in Beijing for the Chinese market.
Business avant-garde with progressive luxury
The EQE features a sporty 'purpose design' with all the characteristic elements of Mercedes-EQ, one-bow lines and cab-forward design. The overall design theme of Sensual Purity is reflected in generously modeled surfaces, reduced joints and seamless transitions. The overhangs and the front end are kept short, the rear provides the dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, the 19- to 21- inch wheels, together with a pronounced muscular shoulder section, give the EQE an athletic character.
Plenty of space for passengers
The EQE is more compact than the EQS and has a wheelbase that is 3.5 inches shorter, at 122.9 inches overall. In terms of external dimensions, it is comparable to the CLS. Like the latter, it has no tailgate but a fixed rear window and a trunk lid. The interior dimensions clearly exceed those of today's E-Class (213 model series), i.e. the shoulder room in the front (+ 1 in) or the interior length (+ 3 in). The seating position is also higher (+ 2.5 in). The interior design and equipment are clearly based on the EQS, with the MBUX Hyperscreen, automatic comfort doors (front) and rear-axle steering, for example, available as optional extras. In terms of noise and vibration comfort (NVH), the EQE is among the best in class.
Range of up to 660 kilometers1
The battery has a usable energy content of 90 kWh, and the range of up to 660 km1 according to WLTP is absolutely suitable for longer drives. The model range will include two variants at market launch: the EQE 350 with 288 hp, as well as a second model that will be announced at a later date. Further versions will follow.
Always up to date
Like the EQS, the EQE offers the possibility to activate completely new vehicle functions via over-the-air updates (OTA) in many areas. Available from launch: the additional sound experience "Roaring Pulse", two special driving modes for young drivers and valet personnel, mini-games, the Highlight mode and DIGITAL LIGHT with projection function and DIGITAL LIGHT individualization. In Highlight mode the vehicle presents an overview of itself and its equipment highlights - this is activated by the "Hey Mercedes" voice assistant. In addition to the light animation "Digital Rain", DIGITAL LIGHT individualization includes other coming- home/leaving animations such as "Brand World". This means that after purchase and the original new car configuration, some of the EQE's equipment can be adapted according to personal preferences.
Navigation with Electric Intelligence
Navigation with Electric Intelligence plans the fastest and most convenient route, including charging stops, based on numerous factors and reacts dynamically to traffic jams or a change in driving style, for example. This includes a visual overview in the MBUX (Mercedes-Benz User Experience) infotainment system as to whether the available battery capacity is sufficient to return to the starting point without charging. Charging stations along the route that have been favorited by the driver are given preference in the route calculation. Proposed charging stations can be excluded. The estimated charging costs per charging stop are also calculated for the driver.
Clean air in the interior
With ENERGIZING AIR CONTROL Plus, Mercedes-Benz takes a holistic approach in regards to air quality in the EQE. The system is based on filtration, sensors, a display concept and air conditioning. The HEPA (High Efficiency Particulate Air) filter has a very high filtration level to trap fine particles, micro-particles, pollen and other substances entering with the outside air. The activated charcoal coating reduces sulphur dioxide, nitrogen oxides and odors in the interior. The interior air filter of this optional feature received "OFI CERT" ZG 250-1 certification in 2021 from the Austrian Research and Testing Institute (OFI) with respect to viruses and bacteria. Using pre-entry climate control, it is also possible to clean the interior air before getting into the vehicle. The fine-particle values outside and inside the vehicle are also displayed in the climate line. If the quality of the outside air is low, the system can also recommend closing the side windows or sunroof, as well as automatically switching to recirculation mode.
Green electricity as standard with Mercedes me Charge
By means of high-quality certificates of origin, Mercedes-Benz guarantees that energy from renewable energy sources is fed into the grid for charging current sourced via Mercedes me Charge. With Mercedes me Charge, customers are able to charge at over 530,000 public charging stations around the world, including nearly 60,000 public places to charge in the USA. With the new Mercedes me Charge Plug & Charge function, the EQE can be charged even more conveniently at Plug & Charge-enabled public charging points: inserting the charging cable automatically starts the charging process. No further authentication by the customer is required.
MBUX Hyperscreen on request
The MBUX Hyperscreen is the absolute highlight in the interior (optional extra). This large, curved screen unit sweeps almost from A-pillar to A-pillar. Three screens sit under a glass cover and appear to merge into one. The 12.3-inch OLED display for the front passenger gives them their own display and control area.
MBUX maintains its lead
With adaptive software, MBUX adapts completely to its user and makes personalized suggestions for numerous infotainment, comfort and vehicle functions. With the new zero layer concept, the most important applications are always offered on the top level within the field of vision, according to situation and context.
Emotive display concept
The EQE follows the EQS visually and in terms of interior displays. The dominant blue color scheme with a highlight in orange is immediately recognizable as "electric world". The Understated mode provides an emotive experience with minimalistic central display. And the optional three display surfaces can be transformed into a common color world in combination with the ambient lighting, the content while in this mode is reduced.
Driving assistance systems support in many driving situations
The latest generation of driving assistance systems includes numerous functions to support the driver. One new function is the microsleep warning from ATTENTION ASSIST (in conjunction with MBUX Hyperscreen). It analyzes the driver's eyelid movements using a camera in the driver display. The assistance display within the driver's display shows the operation of the driving assistance systems in a comprehensible full-screen view.
Interesting facts & figures
The new EQE: at a glance
Depending on the onboard equipment and configuration, WLTP operating ranges of up to
660 kilometers1 are possible.
The torque delivered to the wheels by the eATS (electric drivetrain) is checked 10,000 times per minute and adjusted if necessary. This enables a much quicker response in the later versions with 4MATIC than with mechanical all-wheel drive.
The EQE is available with rear-axle steering as an option. Two versions are optionally available with a steering angle of up to 4.5° and up to 10°. The turning circle is reduced from 41 to up to 35 feet with 10° rear-axle steering.
The electric motor on the rear axle has 2 windings with 3 phases each. This 6-phase design makes this permanently excited synchronous motor (PSM) particularly powerful.
DIGITAL LIGHT (optional extra) has a light module in each headlamp with three extremely bright LEDs whose light is refracted and directed with the help of 1.3 million micro mirrors. The resolution is therefore more than 2.6 million pixels per vehicle.
Mercedes me Charge has one of the densest charging networks, with over 530,000 charging points in 31 countries, including nearly 60,000 public places to charge in the USA.
With the MBUX Hyperscreen (optional extra), multiple displays merge seamlessly to create an impressive curved screen band over 56 inches wide. The area perceived by the occupants measures 2.6 sq. ft.
The large glass covering the MBUX Hyperscreen is curved in three dimensions in a molding process at temperatures of approx. 1202°F. This process allows a distortion-free view of the display unit across the entire width of the vehicle, irrespective of the radius of the glass cover.
A lithium-ion battery with 10 cell modules is installed in the EQE. In the case of the battery, a major step has been achieved in terms of the sustainability of the cell chemistry: the optimized active material consists of nickel, cobalt and manganese in a ratio of 8:1:1.
The optional driving sound of the EQE is interactive and reacts to a dozen different parameters such as the position of the accelerator pedal, speed or recuperation.
No.6 MOOD bittersweet is the name of the fragrance composed especially for the EQE, based on a dark chocolate aroma. It bears the number 6 because the first electric cars were added to the model range in 1906 in the form of the "Mercédès Electrique" vehicles.
To get to the most important applications of MBUX, the user has to scroll through 0 menu levels. Hence the term zero layer.
The display area of the optionally available larger head-up display corresponds to a screen with a diagonal of 77 inches. The imaging unit consists of a high-resolution matrix of 1.3 million individual mirrors.
The HEPA (High Efficiency Particulate Air) filter as part of the optional ENERGIZING AIR CONTROL Plus, with a volume of 9.82 dm³, cleans the incoming outside air at its very high filtration level. Up to 99.75 percent of particles of all sizes are separated. Around 21 ounces of activated charcoal are used to neutralize odors. The adsorption area is equivalent to about 150 football fields.
For haptic feedback during operation, a total of 12 actuators are located under the touchscreen surfaces of the MBUX Hyperscreen. If a finger touches certain spots there, they trigger a tangible vibration in the cover plate.
The EQE is also one of the first vehicles to be built with steel from Salzgitter AG, which is 100 percent recycled. This reduces the CO2 emissions in rolled steel production by more than 60 percent.
A coating on the glass cover simplifies cleaning of the MBUX Hyperscreen. The curved glass itself consists of particularly scratch-resistant aluminum silicate.
8 CPU cores, 24 GB RAM and 46.4 GB per second RAM memory bandwidth are included in the MBUX technical data.
A DC box with a charging capacity of up to 170 kW is fitted on board for (fast) charging via direct current. In 15 minutes it is possible to charge the EQE with up to 35.55 kWh – this corresponds to a range of up to 250 kilometers based on the WLTP range2.
The brightness of the MBUX Hyperscreen's screen is adjusted to the ambient conditions using the measurement data from 1 multifunction camera and an additional 1 light sensor.
With up to seven profiles, the display area of the MBUX Hyperscreen for the front passenger can be individualized.
"Hey Mercedes" supports 27 languages with Natural Language Understanding (NLU).
For high noise and vibration comfort, the electric drivetrains (eATS) have a special foam mat all around as an NVH cover. The lid of the inverter has a sandwich construction of 3 metal and plastic layers.
2 Data on power consumption and range are provisional and were determined internally in accordance with the "WLTP test procedure" certification method. Confirmed TÜV figures, EC type approval and certificate of conformity with official figures are not yet available. Differences between the stated figures and the official figures are possible.

Continuing the good genes of the EQS
The new EQE: the short version
Stuttgart. Just a few months after the introduction of the EQS, Mercedes-EQ is already presenting the next model based on the electric architecture developed specifically for electric vehicles, the new EQE. The sporty executive sedan offers all the essential functions of the EQS in a slightly more compact format. At market launch, the model range initially comprises two variants: the EQE 350 with 288 hp, as well as another model. Further versions will follow. Production of the EQE takes place at two locations of the Mercedes-Benz Cars global production network: at the German Mercedes-Benz plant in Bremen for the global market and at the German-Chinese joint venture BBAC in Beijing for the local market.
Compared to the luxury model EQS, the EQE is even more streamlined, with a slightly shorter wheelbase, shorter overhangs and more recessed flanks - it carries the concept of the executive sedan into the future. Sensual Purity is reflected in generously modeled surfaces, reduced joints and seamless transitions (seamless design). The overhangs and the front end are kept short, the rear provides the dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, the 19- to 21-inch wheels, together with a pronounced muscular shoulder section, give the EQE an athletic character.
In the outer dimensions (length/width/height: 196.6/77.2/59.5 inches), the EQE is comparable to the CLS. Like the latter, it has a fixed rear window and a trunk lid. The interior dimensions even clearly exceed those of today's E-Class (213 model series), i.e. the shoulder room in the front (plus 1 inches) or the interior length (plus 3 inches).
Unconventional interior design and high operating convenience
With the optionally available MBUX Hyperscreen, the entire instrument panel is a single, ultimate widescreen. This determines the aesthetics of the entire cockpit and interior. The high-resolution screens appear to merge seamlessly under the shared glass cover. The graphic appearance of their MBUX content is perfectly coordinated. The MBUX Hyperscreen is integrated into the instrument panel in minimalist fashion.
The vent band boasts a slim design that spans across the entire width at the top. These extreme proportions, together with the glass wave of the MBUX Hyperscreen, create the avant-garde architecture of the cockpit. The outer nozzles feature a turbine design. They play on the theme hyper analogue through the contrast between high-tech precision mechanics and digital, glass display world.
The latest MBUX generation, recently introduced in the EQS, is also on board the EQE. With adaptive software, the control and display concept completely adapts to its user and makes personalized suggestions for numerous infotainment, comfort and vehicle functions. With the zero-layer design, the user does not have to scroll through submenus or give voice commands. The most important applications are offered situationally and contextually on the top level in the field of view. In this way the EQE driver is relieved of certain operating steps.
Efficient drive system
The EQE 350 with 288 hp, plus a second model, will be launched first. Further versions will follow. All EQE models have an electric drivetrain (eATS) on the rear axle. The later versions with 4MATIC are also equipped with an eATS at the front axle. The electric motors are permanently excited synchronous motors (PSM). With the PSM, the rotor of the AC motor is fitted with permanent magnets and therefore does not need to be supplied with power. The advantages of this design include high power density, high efficiency and high power constancy. The motor on the rear axle is particularly powerful due to its six-phase design: it has two windings with three phases each.
In the EQE, the lithium-ion battery consists of ten modules and has a usable energy content of 90 kWh. The innovative battery management software, developed in-house, allows updates over the air (OTA). In this way, the energy management of the EQE remains up-to-date throughout the life cycle.
In the case of the battery, a major step has been achieved in terms of the sustainability of the cell chemistry: the optimized active material consists of nickel, cobalt and manganese in a ratio of 8:1:1. This reduces the cobalt content to less than ten percent. The continuous optimization of recyclability is part of Mercedes- Benz's holistic battery strategy.
Key technical data1
Consistently delivering high performance and multiple accelerations without a drop in power characterizes the EQE's drive philosophy. This includes a sophisticated thermal concept and several variants of energy recovery by means of recuperation. In this process, the high-voltage battery is charged by converting the mechanical rotary motion into electrical energy during overrun or braking mode. The driver can manually select the deceleration in three stages (D+, D, D-) as well as the gliding function via shift paddles behind the steering wheel. Also available: DAuto.
ECO Assist also offers situation-optimized recuperation - deceleration is so strong or weak that it ultimately results in the most efficient driving style. If possible, recuperative deceleration is also used for vehicles detected ahead. This occurs until they come to a standstill, for example at traffic lights. The driver does not need to press the brake pedal for this – allowing for one-pedal driving.
Navigation with Electric Intelligence plans the fastest and most convenient route, including charging stops, based on numerous factors and reacts dynamically to traffic jams or a change in driving style, for example. This includes a visualization in the MBUX infotainment system as to whether the available battery capacity is sufficient to return to the starting point without charging.
High noise and vibration comfort, Sound Experiences as a contrast
As a sedan with a trunk lid, the EQE's concept is well equipped to offer a high level of NVH comfort (Noise, Vibration, Harshness) into account. Numerous measures contribute to this. In the electric drivetrains (eATS), the magnets are arranged inside the rotors in an NVH-optimized way (known as 'sheet metal cut'). In addition, the eATS have a special foam mat all around as an NVH cover. The inverter cover is a sandwich construction. The eATS are double-decoupled from the body via elastomeric bearings:
Highly effective spring/mass components provide continuous sound insulation from the crossmember under the windshield to the floor of the trunk. Acoustic foams are inserted into many carriers during body-in-white construction.
If desired, the ride in the EQE nevertheless becomes an acoustic experience: If the Burmester® surround sound system is on board, the EQE has the two soundscapes: Silver Waves and Vivid Flux. Silver Waves provides a rich and clean sound. Aimed at EV enthusiasts, Vivid Flux is crystalline, synthetic yet humanly warm. They can be selected or switched off as sound experiences on the central display. The additional soundscape Roaring Pulse can be activated as an over-the-air update. This sound experience is reminiscent of powerful machines, and is sonorous and extroverted.
Air suspension and rear-axle steering as options
The suspension of the new EQE, with four-link front suspension and multilink rear suspension, is closely related in design to the new S-Class. As an option, the EQE is available with AIRMATIC air suspension with ADS+ adaptive damping system. With rear-axle steering (optional extra), the EQE feels as maneuverable as a compact car in the city. The steering angle at the rear axle is up to ten degrees. The turning circle is reduced from 41 to 35 feet with rear-axle steering.
New vehicle functions can be activated via over-the-air technology (OTA). Available from launch: the additional sound experience "Roaring Pulse", two special driving modes for young drivers and service personnel, mini games, the highlight mode as well as DIGITAL LIGHT with projection function and DIGITAL LIGHT individualization. In Highlight mode the vehicle presents itself and its equipment highlights - this is activated by the "Hey Mercedes" voice assistant. In addition to the light animation "Digital Rain", DIGITAL LIGHT individualization includes other coming-home/leaving animations such as "Brand World". The OTA functions are available in the Mercedes me Store, and the range of features will be successively expanded.
Convenient charging in a large charging network
With the new Mercedes me Charge Plug & Charge function, the EQE can be charged even more conveniently at Plug & Charge-enabled public charging points: when the charging cable is plugged in, the charging process starts automatically; no further authentication by the customer is required. The vehicle and the charging station communicate directly via the charging cable.
Furthermore, Mercedes me Charge customers continue to benefit from the integrated payment function with automatic payment. The customer chooses the preferred payment method only once. Every charging process is then automatically debited – including charging abroad. The individual charging processes are clearly listed in a monthly invoice.
Mercedes me Charge is one of the largest charging networks worldwide: it currently has more than 530,000 AC and DC charging points in 31 countries, including nearly 60,000 public places to charge in the USA. By means of high-quality certificates of origin, Mercedes-Benz guarantees that energy from renewable energy sources is fed into the grid for charging current sourced via Mercedes me Charge.
High level of passive and active safety
The principles of Integral Safety, in particular accident safety, apply regardless of the platform. Like all other Mercedes-Benz models, the EQE therefore has a rigid passenger cell, special deformation zones and modern restraint systems with PRE-SAFE®.
The fact that the EQE is based on an all-electric architecture which opened up new design possibilities for its safety concept. It meant, for example, that a favorable location could be chosen for the installation of the battery, in a crash-protected area in the underbody. And because there is no large crankcase on board, the behavior in a frontal crash could be modeled even better. In addition to the standard crash tests, the car's performance in various additional load situations was verified and extensive component tests carried out at the Vehicle Safety Technology Centre (TFS).
The latest generation of driving assistance systems includes numerous features that further support the driver. One new function is the additional microsleep warning from ATTENTION ASSIST (in conjunction with MBUX Hyperscreen). It analyzes the driver's eyelid movements using a camera in the driver display. The assistance display within the driver's display shows the operation of the driving assistance systems in a comprehensible full-screen view.
Mercedes management on the EQE
"After the EQS, the EQE is already the second model on our platform for luxury- and premium-class electric vehicles. This speed of innovation shows the advantages of the scalable architecture: With the new EQE, we can quickly make the high-tech solutions of our electric flagship EQS available to a wider group of buyers. And our production flexibility reaches new heights with the EQE: at the Bremen plant, where the versions for the world market roll off the production line, four other models are already in production.”
Markus Schäfer, Member of the Board of Management of Daimler AG and COO of Mercedes-Benz Cars
"2021 is an extremely important year in our electric initiative: with the EQA, EQS, EQB and now EQE, we have celebrated four world premieres of fully electric passenger cars at Mercedes-Benz Cars. With its dynamic driving experience and comprehensive range of Connected Services, the EQE is a perfect fit for the desires of a modern generation of customers. We reconcile innovation and emotionality with sustainability: with Green Charging, we are actively contributing to the reduction of CO2 emissions. In addition, there are numerous intelligent functions that make everyday life easier for our customers. This includes Plug & Charge, for example - plug in and the EQE is charged without further authentication or registration."
Britta Seeger, Member of the Boards of Management of Daimler AG and Mercedes-Benz AG, responsible for Mercedes-Benz Cars Marketing and Sales
“The Mercedes EQE is the next all-purpose electric luxury sedan with the typical One-Bow-Signature Design creating fast lines and silhouette and through that a very aerodynamic and futuristic look. All of this makes the car more flamboyant and entertaining, more extraordinary and defines the next level of luxury for the Mercedes-EQ brand.”
Gorden Wagener, Chief Design Officer Daimler Group

Accelerated transformation from "Electric first" to "Electric only"
The new EQE: sustainability
Mercedes-Benz is setting the course for an all-electric future: by the end of the decade, the brand with the star will be ready to go fully electric - wherever market conditions permit. With this strategic step from "Electric first" to "Electric only", Mercedes-Benz is accelerating its transformation into an emission-free and software-driven future. In many areas, Mercedes is already thinking about tomorrow today: the new EQE is designed to be correspondingly sustainable. Resource-saving materials such as secondary steel are also used. Mercedes-Benz looks at the entire value chain, from development and the supplier network to its own production. Mercedes-Benz AG has had its climate protection targets confirmed by the Science Based Targets Initiative (SBTI). With these goals, the company supports the Paris Climate Accord.
Nine important building blocks of the transformation towards sustainable mobility.
Avant-garde business sedan
The new EQE: the exterior design
The EQE features a sporty 'purpose design' with all the characteristic elements of Mercedes-EQ, one-bow lines and cab-forward design. Sensual Purity is reflected in generously modeled surfaces, reduced joints and seamless transitions (seamless design). The overhangs and the front end are kept short, the rear provides the dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, the 19- to 21- inch wheels, together with a pronounced muscular shoulder section, give the EQE an athletic character.
Compared to the luxury liner EQS, the EQE is even more streamlined, with a slightly shorter wheelbase, shorter overhangs and more recessed flanks - it carries the concept of the executive sedan into the future.
The sporty, low and slim front of the EQE forms a coupe-like silhouette with a bow (one bow) stretched tightly over the greenhouse. The A-pillar, which has been moved far forward, and the C-pillar at the rear create space for a generous passenger compartment. Unique in this segment is the cab-forward design: The overhangs and the front-end assembly are short, the rear forms a dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, the 19- to 21-inch wheels, together with a muscular shoulder section, give the EQE an athletic character.
The design philosophy of Sensual Purity is implemented with the clear, flowing design. Tense, sinewy surfaces emphasize the athleticism, and the claim of seamless design is confidently realized with reduced lines and flowing transitions. Aerodynamics and formal aesthetics are synergistically coordinated. The detailed design expresses innovation and exclusivity.
Black Panel front with Mercedes-Benz pattern on request
The front is combined into a 'Black Panel' unit. Innovative headlights and the deep black radiator grille (Black Panel) form the athletic face and simultaneously position the EQE as a member of the new Mercedes-EQ vehicle family. In addition to its unique look, there is also function behind the Black Panel surface: the various sensors of the driving assistance systems such as ultrasound, camera and radar are integrated. The concise daytime running light signet interprets the brand's characteristic flare. LED High Performance headlamps are standard, DIGITAL LIGHT is available as an optional extra.
The exclusive look of the Black Panel radiator grille with the central Mercedes star can be enhanced still further: in conjunction with AMG Line exterior, includes the Mercedes-Benz pattern, a three-dimensional star pattern. This references the original star of the Daimler-Motorengesellschaft company, which was registered as a trademark in 1911. The seamless design is reflected in the front-end design in particular. Examples include the reduced gap dimensions and overlapping hood. The latter does away with the traditional divide between hood and fenders.
Striking one-bow lines
The aerodynamic silhouette with frameless, coupe-like doors and the high, arched beltline are independent design elements in the profile. The outside mirrors sit on the beltline and are aerodynamically and aero- acoustically optimized. Chrome accents highlight design focal points like the one-bow lines of the window graphics. High-quality painted contrasting surfaces can be found in the lower area of the vehicle. Stone chip protection has been integrated into the chrome trim. The service flap for wiper fluid was integrated into the side of the left wing.
Light band with LED lamps in 3D helix design
The sporty, coupe-like rear carries a rear spoiler with a sharp spoiler lip. The large rear window, which extends downwards from the roof in a flowing contour, is a distinctive feature. For the first time, the components of the various aerials are hidden underneath, invisible from the outside. The trunk lid joins the windshield with a slight gradation and unobtrusively incorporates the additional brake light. The rear camera is hidden behind the star, protected from dirt. Another highlight at the rear are the innovatively designed LED lights: their insides have the shape of a curved and illuminated 3D helix. The EQE has a continuous light band at the rear - a distinguishing feature of Mercedes-EQ vehicles.

In the slipstream of the world champion
The new EQE: aerodynamics
For more than three decades, the aerodynamicists at Mercedes-Benz have been achieving top results. At present the EQS (V 297)1 with a Cd figure of 0.20, the A-Class Sedan (V 177) and the S-Class (V 223) with 0.22 are the world record-holders. The special simulation tools and the Mercedes-Benz aero-acoustics wind tunnel commissioned in 2013 make a decisive contribution to this. The EQE also received its fine- tuning there. It achieves a very good Cd figure thanks to its one-bow design and extensive aerodynamic measures.
After the EQS, it is the second Mercedes EQ to stand on the modular architecture for luxury- and premium- class electric vehicles. The electric sedan therefore shares many aerodynamic measures with its big brother - and is thus in the slipstream of the aerodynamics world champion. The Purpose design with a smooth underbody and mostly closed radiator shutter were a good starting point for flow optimization, although the EQE with shorter front and rear overhangs and standard steel suspension is at a slight conceptual disadvantage.
Mercedes also offers 19 and 20-inch aero-wheels which have been optimized in the wind-tunnel. Among them is a two-tone light-alloy wheel with an almost fully closed surface but visible high-sheen rim flange.
Behind the very good aerodynamic performance is a lot of detail work. The non-visible details in particular, for example on the underbody, were developed particularly intensively. Several thousand computational runs were performed in the virtual wind tunnel alone. Below are some details of the aero development:
In an electric car without the usual level of powertrain noise, wind noise is particularly noticeable by the occupants. That's why the aeroacoustics behavior is particularly important. In this area too, the new EQE is one of the very best vehicles in its class.
Lots of fine-tuning in the details: in order to reduce or prevent low-frequency noises that can be perceived as reducing comfort, numerous cavities in the car body were filled with acoustically effective foam, for example.
It was also possible to reduce the high-frequency components of the wind noise in the EQE through improved seals on the door handles, the window supports and the outside mirrors. The aero acousticians paid special attention to the seals of the transitions between the six side windows. This concept is new to Mercedes-Benz vehicles and was first used in the EQS. Another contribution is made by the A-pillar with a specially shaped trim element at the transition to the windshield. In its development, both modern flow simulations and external noise measurements by means of a special microphone array in the wind tunnel were used. The A-pillar designed in this way not only improves the aeroacoustics, but is also important for a low cd figure and in keeping the windows free of dirt.
The Acoustic Comfort Package further enhances noise comfort. This includes acoustically effective laminated glass on the front side windows and additional insulation in the interior. On the panoramic roof, various wind deflectors, covers and seals with improved geometry ensure high noise comfort despite the large roof opening.
1 EQS 450+ (combined NEDC power consumption: 18.9-16.2 kWh/100 km; CO2 emissions: 0 g/km) with 19-inch AMG wheel/tyre combination and AMG Line exterior (available in the EU from the end of 2021) in the SPORT drive program. The power consumption (and information based thereon) has been determined on the basis of Commission Regulation (EC) 692/2008 according to NEDC and Commission Regulation (EU) 2017/1151 according to WLTP

Systematic digitalization and unusual materials
The new EQE: the interior design
The EQE is the new executive class sedan from Mercedes-EQ. With this completely new vehicle, the designers had the opportunity to take a completely new approach to the interior design as well. They used this freedom and, in addition to the MBUX Hyperscreen, relied on consistent digitalization and avant-garde design for many other elements.
Like the EQS, the EQE is based on a large electric platform from Mercedes-EQ. For the designers, this went hand in hand with the vision of systematic digitalization of the interior. The optionally available MBUX Hyperscreen implements this vision in a particularly impressive way: the entire instrument panel is one ultimate widescreen. This determines the aesthetics of the entire cockpit and interior. The real glass appears to drape itself three-dimensionally over the entire width of the vehicle like a wave - a unique feature in automotive construction to date.
The high-resolution screens merge seemingly seamlessly under the shared glass cover. The graphic appearance of their MBUX content is perfectly coordinated. The MBUX Hyperscreen is integrated into the instrument panel in minimalist fashion. Only a fine frame in silver shadow, a band of nozzles and a narrow leather ledge enclose the MBUX Hyperscreen. The leather ledge is reminiscent of the lower section of classic instrument panels.
The vent band spans across the entire width at the top and is very slim at the same time. These extreme proportions, together with the glass wave of the MBUX Hyperscreen, create the avant-garde architecture of the cockpit. For further details on the MBUX Hyperscreen, see separate chapter.
The dominant outer vents have a turbine design. They deliberately play on the theme of hyper analogue through the contrast between high-tech precision mechanics and digital, glass display world. The intricately designed turbine blades distribute the airflow efficiently.
The front section of the center console joins the instrument panel and stands freely in space. It is a visual reference to the new drive architecture – due to the electric powertrain, no transmission tunnel is necessary. Flowing leather surfaces with intricate seam dressings create a modern and luxurious impression in combination with the large-scale real wood blind. At the same time, there is plenty of practical storage space available.
The standard model without MBUX Hyperscreen has a slightly different center console. There is a soft armrest in the rear section. It is first visually interrupted before being transitioned into the floating central display. The smooth transition from 3D in the center console compartment to 2D on the touchscreen is seamless, i.e. without interrupting the glass look, and is unique.
Door trim modern, avant-garde and extremely reduced design
The vent band from the cockpit is visually continued in the driver's doors. A floating control cluster with integrated door opener and seat controls takes over the functional interpretation of formerly purely decorative elements. The door center panel develops in a sensual, dynamic movement from the vertical surface into the horizontal and thus integrates the armrest seamlessly. The front section of the armrest is designed as a metallic high-tech element that can be used as a free-floating grab and pull handle and contains the power window switch. In the dark, this floating, avant-garde aesthetic is particularly impressive thanks to an ambient light corona.
Seats: elaborately processed materials and perforations
Standard interior equipment includes the comfort seats. Despite their simplicity of design, they captivate with their sculptural beauty. Wrap-around surfaces in the side bolsters create the body support and stand in stark contrast to the seat center panel. It has a sophisticated seam pattern similar to a fan palm.
In combination with AMG Line interior, the EQE receives the sports seats. These are characterized by a slim and monolithic shape and act like integral seats. The seat surfaces are designed in such a way that they give the impression of draped-on leather covers. The technical term is "layering".
Common features of all leather seats are the dynamic graphic patterns with highly elaborate perforations. Here, too, you will find the hallmark Mercedes-EQ combination of the highest standards in materials, ambience and workmanship as well as state-of-the-art technology.
Color & trim: avant-garde and tradition for a special ambience
Avant-garde as well as traditional materials and colors give the interior a special atmosphere.
The modern delicate structure NEOTEX combines the look of nubuck leather and high-tech neoprene. It is found on the instrument panel, the armrest and the seats of the interior.
Six coordinated color combinations in the interior emphasize the generous feeling of space. The EQE is immersed in a progressive and luxurious color scheme of warm and cool tones. Colors such as Sable Brown/Neva Grey and Biscaya Blue/Black add the finishing touches to the soft and emotive design. The color rose gold, derived and evolved from the electric coil, emphasizes the design of the vent band and is used as a contrasting color.
The innovative trim parts make a key contribution to the aesthetics in the EQE. Three examples: a new trim in brown natural grain wood with grey printing of magnolia wood. The anthracite 3D relief-look trim, on the other hand, has fine metallic pigments. The different lighting situations in the vehicle subtly change the appearance and enhance the perceived value.
The laser-cut trim elements backlit with Mercedes-Benz pattern also create a special ambience. The star pattern is lasered into the plastic trim and is adaptively backlit. Innovative wood trim can also be selected, for example anthracite open-pore fine line lime wood.
A special welcome & goodbye scenario1 has been developed for the Mercedes-EQ models, which is also coordinated with the ambient lighting.
UX design: multiple display styles and modes to choose from
As with the EQS, the functional content and operating structure are adapted to electric driving. Visually, all graphics are designed in a new color scheme of blue/orange throughout. The classic cockpit display of the two round dials has been reinterpreted with a digital lightsaber in a glass lens. All content relevant to driving can be accessed between the round dials.
The "sport" display takes the form of a spatial power bar and conveys the relevant driving status (Drive, Accelerate, Charge) emotionally and impressively. The central object here is a "G-force puck", which dynamically moves in line with the acceleration forces.
The appearance of the screens can be individualized with three display styles (Understated, Sporty, Classic) and three modes (Navigation, Assistance, Service).
For a very calm interior impression, the Understated mode familiar from the S-Class has been adapted. In the EQE, the content of the displays is reduced as much as possible and coordinated with the color change of the ambient lighting in seven screen color worlds. In "Assistance" mode, important events such as lane changes or target distance control as well as the infrastructure and detected users on the road (cars, motorcycles, trucks) are displayed.

The EQE 350 as a harbinger of a model family
The new EQE: electric drive
The models available at launch are the EQE 350 with 288 hp, and a second model. Further versions will follow. The battery has ten modules with a usable energy content of around 90 kWh, and the range of up to 660 km according to WLTP is absolutely suitable for longer drives.
All EQE models have an electric drivetrain (eATS) on the rear axle. The later versions with 4MATIC also have an eATS on the front axle. In the 4MATIC models, the Torque Shift function ensures intelligent, continuously variable distribution of drive torque between the rear and front electric motors and thus the use of the most efficient eATS in each case. The modular powertrain concept ensures high overall performance and long range.
The electric motors on the front and rear axles are permanently excited synchronous motors (PSM). With the PSM, the rotor of the AC motor is fitted with permanent magnets and therefore does not need to be supplied with power. The magnets – and thus the rotor – follow the rotating alternating current field in the stator windings. In the EQE, Mercedes-Benz uses what is known as a pull-in winding for a particularly strong magnetic field. The engine is referred to as synchronous because the rotor turns at the same rate as the magnetic field of the stator. The frequency is adjusted in the power electronics converters to the speed requirements of the driver. The advantages of this design include high power density, high efficiency and high power constancy. The motor on the rear axle is particularly powerful due to its six-phase design: it has two windings with three phases each.
Cooling: sophisticated thermal concept for high load capacity
Consistently producing high performance and multiple accelerations without a drop in power characterizes the EQE's drive philosophy. This includes a sophisticated thermal concept with some special features. What is known as a water lance in the shaft of the rotor cools it from the inside. Other cooling elements in the cooling circuit are fins on the stator, a needle-shaped pin-fin structure on the inverter and a transmission oil cooler. This also brings more efficiency when driving in cooler temperatures, as the heat exchanger serves to heat the transmission oil and thus reduces friction in the transmission.
Intelligent recuperation: one-pedal driving to a standstill
The EQE offers several variants of energy recovery by means of recuperation: in this process, the high-voltage battery is charged by converting the mechanical rotary motion into electrical energy during overrun or braking mode. The driver can manually select the deceleration in three stages (D+, D, D-) as well as the gliding function via shift paddles behind the steering wheel. Also available: DAuto.
ECO Assist also offers situation-optimized recuperation - deceleration is so strong or weak that it ultimately results in the most efficient driving style. Recuperative deceleration is also used as far as possible for vehicles detected ahead until they come to a standstill, for example at traffic lights. The driver does not need to press the brake pedal for this – allowing for one-pedal driving.
Noise and vibration comfort: conceptual advantage plus extensive measures
As a sedan with a trunk lid, the EQE's concept is well equipped to offer a high level of NVH comfort. Numerous measures contribute to this:
The design of the electric powertrains (eATS) takes noise and vibration comfort (NVH - Noise, Vibration, Harshness) into account. The magnets are arranged inside the rotors in an NVH-optimized way (known as 'sheet metal cut'). This also reduces the use of rare earths. The shape of the winding, what is known as the stator tilt, also supports vibration comfort, especially at low speeds. In relation to the permanent magnets of the rotor, the coils of the stator are obliquely wound. Otherwise, what is known as cogging torque could occur. This would lead to slight but unpleasant vibrations when driving very slowly.
In addition, the eATS have a special foam mat all around as an NVH cover. The inverter cover has a sandwich construction of three metal and plastic layers. The eATS are doubly decoupled from the body via elastomeric bearings: at the front axle opposite a supporting frame and this against the body, at the rear axle with a subframe.
Highly effective spring/mass components provide continuous sound insulation from the crossmember under the windshield to the floor of the trunk. Acoustic foams are inserted into many carriers during body-in-white construction.
The electric refrigerant compressor has an NVH cover as encapsulation. In the rear-wheel-drive EQE, it is also soft-suspended, while in the 4MATIC models it is bolted directly to the front eATS. The operating strategy of the refrigerant compressor was designed for the highest possible noise and vibration comfort. Certain rpm ranges at which disturbing resonances may be audible when stationary or in a traffic jam are avoided or quickly passed through.

Fast laps in the hall
The new EQE under the magnifying glass: the eDrive test benches
One fast lap after another on the high-speed oval in Nardò in southern Italy, winding uphill and downhill stretches on the Swabian Jura or stop-and-go traffic for hours on the Stuttgart Weinsteige. And without ever leaving their workplaces in Untertürkheim, because they "drive a car without a car", Mercedes-Benz tests the drives of electric cars on eDrive test benches.
The electric drive of models in the fast-growing Mercedes-EQ family is being tested on a total of 13 test benches in Untertürkheim. Of these, seven are pure eATS test benches, where the power comes from a special direct current source, what is known as a battery simulation. On the six eDrive test benches, testing also includes the battery and the complete charging components of the vehicle. In addition, there are 13 test benches at the Nabern development site.
The test benches are connected to a monitoring room with computers. The most important measurement parameters for the test operation are visualized on one of the many monitoring screens. They tell the test bench driver in real time during the test whether everything is in order or whether a problem is imminent. Almost year round, the testing operation runs around the clock. Over the weekends, there is an on-call service; automatic shutdowns are communicated to the staff members responsible via instant messages or push messages on their smartphones. Remote access to the automation, diagnostic and measuring computers is possible.
The trial program: a whole car lifetime is simulated
All electric drivetrains (eATS) for all series are tested on the test benches. Both in terms of function and efficiency as well as durability. On the test benches, the eATS are coupled to load machines via the drive shafts installed in the vehicle - just like the drivetrain with a combustion engine and transmission on conventional test benches. At each rotational speed, they simulate different stresses on the e-drive.
The testing programs depict high-speed and road endurance runs. For this purpose, the test benches are programmed with data from real routes, topography and corresponding load conditions, for example acceleration, staying on the gas, kickdown or recuperation. For example, Nardò, the Swabian Jura and the Stuttgart Weinsteige take place in the hall. And for security reasons, without spectators.
With accelerated endurance runs, an entire car lifetime is simulated within a few months and with many megawatt hours of electricity. In this way, weak points can be detected in the shortest possible time and the drivelines optimized in good time before series production starts.
How long an eATS is tested on the test bench depends on the respective test program. The range extends from several weeks for testing individual functions to a whole year for an endurance run.

Powerful cell chemistry meets intelligent software
The new EQE: the traction battery1
The scalability of the battery system in the new Mercedes-EQ models of the luxury and premium class enables the realization of different range and performance variants. In the EQE, the lithium-ion battery consists of ten modules. The innovative battery management software, developed in-house, allows updates over the air (OTA). In this way, the energy management of the EQE remains up-to-date throughout the life cycle.
Battery development is a decisive factor in Mercedes-Benz's electrification strategy. After all, the battery is the heart of an electric car and makes a decisive contribution to, among other things, the range and thus the driving characteristics of the electric vehicle. With the EQS, a new generation of batteries with significantly higher energy density has been launched, from which the EQE now also benefits. The new batteries set standards in terms of performance, efficiency and charging capacity.
They also meet the high Mercedes requirements in terms of safety, durability and sustainability.
Mercedes-Benz issues a battery certificate for its high-voltage batteries, and thus a performance warranty for customers: 10 years or a mileage of 155,000 miles with a defined residual capacity.
Comprehensive battery expertise
The highly efficient batteries were developed entirely in-house by the team of experts at the Mercedes-Benz Battery Competence Center. The software for the intelligent management system was also developed and programmed in-house. The batteries are produced in the Hedelfingen section of the Stuttgart-Untertürkheim site.
A lithium-ion battery with ten cell modules is installed in the EQE. In the case of the battery, a major step has been achieved in terms of the sustainability of the cell chemistry: the optimized active material consists of nickel, cobalt and manganese in a ratio of 8:1:1. This reduces the cobalt content to less than ten percent. The continuous optimization of recyclability is part of Mercedes-Benz's holistic battery strategy. The aim is to be able to dispense entirely with materials such as cobalt through the use of innovative post-lithium-ion technologies.
Intelligent operating strategy for maximum range
The battery is integrated into the intelligent thermal management of the EQE. If the intelligent navigation with Electric Intelligence is activated, the battery is preheated or cooled as needed while driving to reach the best possible temperature for efficient charging at the charging point. The desired temperature range of the battery is achieved with the aid of the cooling circuit and a PTC (Positive Temperature Coefficient) booster heater integrated into it.
Complex protection concept for safety
As a matter of principle, Mercedes-Benz applies very high safety standards to all of its models. This means that, in many cases, internal Mercedes-Benz safety standards exceed legal requirements. The crash-related requirements in particular are aligned to the "Real Life Safety" philosophy. In the process, findings from internal accident research are incorporated into the development specifications. Alongside verification of crash behavior, all Mercedes-Benz vehicles undergo additional component tests at system level.
The battery sits in a crash-protected area in the underbody, embedded in the body shell structure including an extruded aluminum profile on the side. In extrusion, a heated block of metal is forced through dies and transformed into a continuous profile, which is then cut to fit. In this way, highly complex profiles can be produced that are precisely tailored to the requirements. The housing with energy absorbing structures at the front and side as well as a rigid, double-walled base plate provide additional protection for the modules. The test criteria include, among other things, the battery behavior under shock load and in the event of foreign object penetration. Overheating and overcharging were also simulated and tested. In addition, there is a separate, multi-level safety system for everyday operation. This includes, for example, temperature, voltage or insulation monitoring as a continuously monitoring safety system. If an error occurs, the battery is switched off.
Production: battery systems from Hedelfingen
The batteries for the Mercedes-EQ electric vehicles are supplied by the global battery production network with factories on three continents. Local battery production is a key success factor for Mercedes-Benz's electric initiative.
The battery systems for the EQE are produced in the Hedelfingen section at the Stuttgart-Untertürkheim site. Absolute precision is required in their manufacture. The battery systems consist of a variety of components, including ten cell modules and what is known as the EE compartment for the intelligent integration of the power electronics. It is assembled at the Mercedes-Benz site in Berlin.
The Mercedes-Benz Hedelfingen plant will have carbon-neutral production from 2022. The plant is a prime example of the transformation of production sites as part of the Mercedes-Benz Electric First strategy. The efficient and seamless integration of battery production alongside existing transmission production transforms Hedelfingen's traditional role as a site for conventional powertrain components into an important part of the company's global battery production network.
Mercedes-Benz has already agreed the CO2-neutral production of battery cells with two major suppliers. The supplier network accounts for a substantial share of value creation, and is therefore of decisive importance for the decarburization targets. Because of the higher energy requirements in the production of fully electric vehicles, the supplier network is a key component in achieving the climatic targets of Mercedes-Benz.

Always connected
The new EQE: the charging functions
Three charging programs are offered in the EQE - Standard, Home and Work. Within these, parameters such as departure time, air conditioning and maximum charge level can be preset. The Home and Work charging programs can be activated based on location. This means that they are switched on automatically as soon as the vehicle is parked at a charging point at the GPS positions stored in the system. The user is informed about this through MBUX.
The EQE also has these intelligent charging functions:
A latest-generation charging system sits above the rear axle of the EQE. It can be used to charge the battery via the public power grid with single-phase or three-phase alternating current and an optional charging capacity of up to 22 kW in Europe. In addition, intelligent wallboxes from national partners are available to customers in the individual markets. Mercedes-Benz also offers an installation service for these wallboxes. This includes a preliminary check of the installation conditions, a detailed consultation and of course the installation.
A DC box with a charging capacity of up to 170 kW is fitted on board for (fast) charging via direct current. High charging currents can be maintained for a long time through temperature and charging management. Power for up to another 250 kilometers (WLTP) is recharged in just 15 minutes1.
The actual charging time depends on the battery size, the available infrastructure and the country-specific vehicle equipment. The charging socket is located at the rear right of the vehicle and is designed according to market requirements:
1 Charging speed at DC fast charging stations with 500 amps. Power consumption figures are provisional and were determined internally in accordance with the "WLTP test procedure" certification method. Confirmed TÜV figures, EC type approval and certificate of conformity with official figures are not yet available. Differences between the stated figures and the official figures are possible.

Because the shortest route is not always the fastest
The new EQE: Navigation with Electric Intelligence
As far as Navigation with Electric Intelligence is concerned, the name says it all. Because it plans the fastest and most convenient route, including charging stops, based on numerous factors and reacts dynamically to traffic jams or a change in driving style, for example. With the EQE, Navigation with Electric Intelligence is particularly advanced, for example, it is able to calculate estimated charging costs per charging stop. Furthermore, the customer can edit the planned routes individually by adding in preferred charging stations along the route or excluding proposed charging stations.
While a conventional range calculator relies on past data, the Navigation with Electric Intelligence system looks into the future. The energy demand is computed for the calculation of the route. The topography, route, ambient temperature, speed, heating and cooling requirements are all taken into account. Further factors include the traffic situation along the planned route, as well as the available charging stations that can be found there, their capacity and payment functions. Calculation takes place in the Cloud and is combined with on-board data.
The customer does not necessarily always have to take on a full charge, but will be given a specific recommendation as to the required charging time at the charging station. The charging station stops will be planned in the way that provides the maximum benefit for the overall traveling time: under certain circumstances, two short charging stops with a higher charging power can be more advantageous than charging once for a long time. In addition, Navigation with Electric Intelligence automatically adjusts the vehicle's charging settings and optimizes them for fast charging along the route.
MBUX displays whether the available battery capacity is sufficient to return to the starting point without charging. Charging stations along the route that have been added manually are given preference in the route calculation. Proposed charging stations can be excluded. The estimated charging costs per charging stop are calculated.
If there is a risk of not reaching the destination or the charging station with the selected settings, Active Range Monitoring issues the prompt to activate ECO driving functions. In addition, the driving speed for reaching the next charging station or the destination is calculated and displayed in the speedometer. Under the menu item "Range", the EQE driver can switch off various energy consumers to increase the range and activate the ECO driving functions to support a more efficient driving style.

Further reducing the carbon footprint with green power
The new EQE: Mercedes me Charge
With Mercedes me Charge, customers can charge green at every public charging station throughout the United States. High-quality guarantees of origin ensure that as much green power from renewable energies is fed into the grid as is withdrawn via Mercedes me Charge. In the first two years after the purchase of an EQE, there is no basic charge for Mercedes me Charge and thus Green Charging for customers. With the new Plug & Charge function, the EQE can be conveniently charged.
Mercedes me Charge is one of the largest charging networks worldwide: it currently has more than 530,000 AC and DC charging points in 31 countries, and nearly 60,000 public places to charge in the USA. At selected charging stations, such as Electrify America’s fast charging network, green power is already being offered. Mercedes me Charge is now significantly expanding this opportunity to further reduce the carbon footprint: with Mercedes me Charge, customers are able to charge green at every public charging station throughout the United States. In addition, the functionality of Mercedes me Charge in MBUX will be expanded to include functions such as filtering and forecasting the availability of charging stations.
How Green Charging works: to promote the use of electricity from renewable energies, Mercedes-Benz uses guarantees of origin to 'green' the charging process, whose quality is defined by an eco power label. This ensures that an equivalent amount of electricity from renewable resources is fed into the grid to compensate for the charging of an electric vehicle. Amounts of energy used for charging are thus offset with green power after the actual charging process, also creating incentives to invest in renewable energy plants. In the first two years after the purchase of an EQE, there is a fee for Mercedes me Charge. The prices of the charging operator may vary. Green charging and driving become tangible with MBUX.
Plug & Charge - simpler and more convenient charging
With the new Mercedes me Charge Plug & Charge function, the EQE can be charged even more conveniently at Plug & Charge-enabled public charging points: when the charging cable is plugged in, the charging process starts automatically; no further authentication by the customer is required. The vehicle and the charging station communicate directly via the charging cable.
Furthermore, Mercedes me Charge customers continue to benefit from the integrated payment function with automatic payment. The customer is able to choose their preferred payment method once, then every charging process is then automatically debited – including charging abroad. The individual charging processes are clearly listed in a monthly invoice.
Whether a charging station is Plug & Charge-compatible can be seen by the charging station details shown on the central display of the EQE and in the Mercedes me App. It is also possible to search for specific, suitable charging stations. This convenient authentication method will initially be available at the Electrify America fast charging stations throughout the United States. Plug & Charge is the fourth way to access charging points, alongside enabling via MBUX on the vehicle's media display, the Mercedes me App and the Mercedes me Charge card.
Mercedes me App: easy operation on smartphone and tablet
The Mercedes me App offers many improved and new functions since the last revision. These include a filter option that allows the charging points to be sorted according to criteria such as availability or charging capacity. The likelihood over the course of the day of a particular charging point being busy is also determined and displayed on the basis of a probability calculation.

High levels of driving dynamics and handling
The new EQE: the suspension
The suspension of the new EQE, with four-link front suspension and multilink rear suspension, is closely related in design to the new S-Class. Rear-axle steering with a steering angle of up to 10° is available as an option for ease of maneuverability in town and agility out of town. Optionally, the EQE is also available with AIRMATIC air suspension with ADS+ adaptive damping system.
The EQE has the proven four-link front suspension. Its multilink rear suspension is designed to integrate the rear-axle steering. The suspension subframe carriers and the elastomeric bearings of the rear axle struts were improved in terms of NVH and driving characteristics by conducting extensive simulations and driving tests.
The optional AIRMATIC air suspension responds particularly perceptively, as it combines air suspension bellows with adaptive ADS+ dampers whose characteristics can be fully automatically varied at each individual wheel, in both the compression and rebound stages. While driving, a sophisticated sensor system and algorithms set the dampers according to the quality of the road to ensure that, for example, driving over a bump with just one wheel is not transmitted to the entire axle and the interior. Spring and damper are combined in one strut on the front axle.
This level control is part of AIRMATIC. It keeps the ground clearance constant irrespective of the vehicle load, but also makes changes when needed. By way of example, in the SPORT program the vehicle body is lowered by 1 inch at high speeds above 75 mph to reduce aerodynamic drag and increase handling stability. If the vehicle drops below 50 mph, the body level returns to the initial position. Up to 25 mph the body can be raised by 1 inch at the touch of a button, above 30 mph it is automatically lowered back to normal level.
As maneuverable as a compact car: both axles can do the steering
Thanks to rear-axle steering (optional extra), the EQE feels as maneuverable as a compact car in the city. The steering angle at the rear axle is up to ten degrees. The turning circle is reduced from 41 to 35 feet with rear- axle steering.
The interaction between front-axle and rear-axle steering has been designed to achieve agile response with low steering effort in city and country road driving, but at the same time very high stability. This results in i.e. small side-slip angles and a high level of yaw suppression. At high speeds the focus is more on stability, though without compromising precision and responsiveness. This added value is achieved by integrated actuation of the steering and brakes (ESP®), and considerably improves handling safety as a result.
Depending on the tires selected, customers can choose between two versions of the optional rear-axle steering with a maximum steering angle of 4.5° and 10°.
DYNAMIC SELECT: the EQE drives the way the driver wants it to drive
The driver can individually modify the characteristics of the powertrain, ESP®, suspension and steering. The selection is made using a control at the lower end of the central display. The default setting is the COMFORT drive program, with SPORT, ECO and INDIVIDUAL available as alternatives. The selection is acknowledged by acoustic and visual feedback. The desired drive program is shown as the status and depicted in the central display.

Zero-layer design: the most important things are now only one click away
The new EQE: MBUX (Mercedes-Benz User Experience)
MBUX (Mercedes-Benz User Experience) has radically simplified the operation of a Mercedes-Benz. Introduced in 2018 in the current A-Class, more than 1.8 million Mercedes-Benz passenger cars are now on the road with it, and the Vans division is also relying on MBUX. The second generation of this adaptive system was launched in the new S-Class, followed by the next big step with the EQS. With adaptive software, the control and display concept completely adapts to its user and makes personalized suggestions for numerous infotainment, comfort and vehicle functions. With the zero-layer design, the user does not have to scroll through submenus or give voice commands. The most important applications are offered situationally and contextually on the top level in the field of view. This relieves the EQE driver of numerous operating steps. Mercedes-Benz has integrated numerous music streaming providers holistically into the MBUX Infotainment system with the "Online Music" service.
Infotainment systems offer numerous and extensive functions. Several operating steps are often required to control them. In order to reduce these interactive steps even further, with the aid of artificial intelligence Mercedes-Benz has developed a user interface with context-sensitive awareness.
The MBUX system proactively displays the right functions at the right time for the user, supported by artificial intelligence. The context-sensitive awareness is constantly optimized, both by changes in the surroundings and by user behavior. The 'zero layer' offers the user dynamic, aggregated content from the entire MBUX system, and thus the associated services, on the uppermost level of the MBUX information architecture.
Mercedes-Benz has investigated the usage behavior of the first MBUX generation. Most of the use cases fall within the Navigation, Radio/Media and Phone categories. The navigation application with its full range of functions is therefore always in the center of the visual display unit.
Over 20 other functions - from ENERGIZING COMFORT to birthday reminders and suggestions for the to-do list - are automatically offered with the help of artificial intelligence when they are relevant to the customer. The developers have internally christened these suggestion modules, which are displayed on the zero-layer interface, "Magic Modules".
Here are three representative use cases. The user can accept or reject the respective suggestion with just one click:
The EQE has the latest MBUX generation. The impressive MBUX Hyperscreen is available as an option. There, the front passenger also has their own screen.
Face recognition with cameras in the driver display is used for a wide range of assistance and comfort functions. These include biometric authentication, ATTENTION ASSIST drowsiness warning and adjusting the outside mirrors to the pre-set position. In combination with the standard Display Package or the MBUX Hyperscreen, a fingerprint scanner for driver authentication is on board.
Hey Mercedes: the voice assistant can now do even more
Compared with the previous MBUX generation, the "Hey Mercedes" voice assistant is even more capable of dialogue and learning by activating online services in the Mercedes me App. Moreover, certain actions can be performed even without the activation keyword "Hey Mercedes". These include taking a telephone call. "Hey Mercedes" now also explains vehicle functions, and can help for example when asked how to connect a smartphone by Bluetooth or where the first-aid kit can be found. "Hey Mercedes" is now also able to recognize vehicle occupants by their voices. Once the individual characteristics of the voice have been learned, this can be used to access personal data and functions by activating a profile.
Online music: music streaming with millions of songs to choose from
With the "Online Music" service, Mercedes-Benz has now fully integrated the major music streaming services - Spotify, Amazon Music and recently also Apple Music - into the MBUX infotainment system. MBUX enables access to the personal user profile at the linked music providers. This allows customers to seamlessly access their favorite songs and playlists and discover millions of songs as well as curated playlists. Operation is intuitive using the MBUX voice assistant via "Hey Mercedes" and via touch controls on the steering wheel or central display.
Personalization is simple and convenient
A personal profile can be created directly in EQE and synchronized with existing profile data of the Mercedes me account. By scanning a QR code with the Mercedes me App, the vehicle is automatically connected to the Mercedes me account.
Personal preferences such as a favorite radio station and preselected settings can be transferred to any seat via the personal Mercedes me profile. Up to seven different profiles with a total of around 800 parameters are possible in the vehicle. As the profiles are stored in the Cloud as part of Mercedes me, the profiles can also be used in other Mercedes-Benz vehicles with the new MBUX generation.
In addition to the classic entry of a PIN, a special authentication procedure ensures a high level of security. Fingerprint, face and voice recognition are combined. This allows access to individual settings or verification of digital payment processes from the vehicle.

The essential information and innovations
The new EQE1: the main points at a glance
The executive sedan EQE is the second model to be based on the premium-class electric architecture (EVA2), following the luxury EQS sedan. The EQE will celebrate its world premiere at the IAA show (September/Munich). The staggered global launch will begin mid-2022. Production will be in Bremen for the world market and in Beijing for the Chinese market.
Business avant-garde with progressive luxury
The EQE features a sporty 'purpose design' with all the characteristic elements of Mercedes-EQ, one-bow lines and cab-forward design. The overall design theme of Sensual Purity is reflected in generously modeled surfaces, reduced joints and seamless transitions. The overhangs and the front end are kept short, the rear provides the dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, the 19- to 21- inch wheels, together with a pronounced muscular shoulder section, give the EQE an athletic character.
Plenty of space for passengers
The EQE is more compact than the EQS and has a wheelbase that is 3.5 inches shorter, at 122.9 inches overall. In terms of external dimensions, it is comparable to the CLS. Like the latter, it has no tailgate but a fixed rear window and a trunk lid. The interior dimensions clearly exceed those of today's E-Class (213 model series), i.e. the shoulder room in the front (+ 1 in) or the interior length (+ 3 in). The seating position is also higher (+ 2.5 in). The interior design and equipment are clearly based on the EQS, with the MBUX Hyperscreen, automatic comfort doors (front) and rear-axle steering, for example, available as optional extras. In terms of noise and vibration comfort (NVH), the EQE is among the best in class.
Range of up to 660 kilometers1
The battery has a usable energy content of 90 kWh, and the range of up to 660 km1 according to WLTP is absolutely suitable for longer drives. The model range will include two variants at market launch: the EQE 350 with 288 hp, as well as a second model that will be announced at a later date. Further versions will follow.
Always up to date
Like the EQS, the EQE offers the possibility to activate completely new vehicle functions via over-the-air updates (OTA) in many areas. Available from launch: the additional sound experience "Roaring Pulse", two special driving modes for young drivers and valet personnel, mini-games, the Highlight mode and DIGITAL LIGHT with projection function and DIGITAL LIGHT individualization. In Highlight mode the vehicle presents an overview of itself and its equipment highlights - this is activated by the "Hey Mercedes" voice assistant. In addition to the light animation "Digital Rain", DIGITAL LIGHT individualization includes other coming- home/leaving animations such as "Brand World". This means that after purchase and the original new car configuration, some of the EQE's equipment can be adapted according to personal preferences.
Navigation with Electric Intelligence
Navigation with Electric Intelligence plans the fastest and most convenient route, including charging stops, based on numerous factors and reacts dynamically to traffic jams or a change in driving style, for example. This includes a visual overview in the MBUX (Mercedes-Benz User Experience) infotainment system as to whether the available battery capacity is sufficient to return to the starting point without charging. Charging stations along the route that have been favorited by the driver are given preference in the route calculation. Proposed charging stations can be excluded. The estimated charging costs per charging stop are also calculated for the driver.
Clean air in the interior
With ENERGIZING AIR CONTROL Plus, Mercedes-Benz takes a holistic approach in regards to air quality in the EQE. The system is based on filtration, sensors, a display concept and air conditioning. The HEPA (High Efficiency Particulate Air) filter has a very high filtration level to trap fine particles, micro-particles, pollen and other substances entering with the outside air. The activated charcoal coating reduces sulphur dioxide, nitrogen oxides and odors in the interior. The interior air filter of this optional feature received "OFI CERT" ZG 250-1 certification in 2021 from the Austrian Research and Testing Institute (OFI) with respect to viruses and bacteria. Using pre-entry climate control, it is also possible to clean the interior air before getting into the vehicle. The fine-particle values outside and inside the vehicle are also displayed in the climate line. If the quality of the outside air is low, the system can also recommend closing the side windows or sunroof, as well as automatically switching to recirculation mode.
Green electricity as standard with Mercedes me Charge
By means of high-quality certificates of origin, Mercedes-Benz guarantees that energy from renewable energy sources is fed into the grid for charging current sourced via Mercedes me Charge. With Mercedes me Charge, customers are able to charge at over 530,000 public charging stations around the world, including nearly 60,000 public places to charge in the USA. With the new Mercedes me Charge Plug & Charge function, the EQE can be charged even more conveniently at Plug & Charge-enabled public charging points: inserting the charging cable automatically starts the charging process. No further authentication by the customer is required.
MBUX Hyperscreen on request
The MBUX Hyperscreen is the absolute highlight in the interior (optional extra). This large, curved screen unit sweeps almost from A-pillar to A-pillar. Three screens sit under a glass cover and appear to merge into one. The 12.3-inch OLED display for the front passenger gives them their own display and control area.
MBUX maintains its lead
With adaptive software, MBUX adapts completely to its user and makes personalized suggestions for numerous infotainment, comfort and vehicle functions. With the new zero layer concept, the most important applications are always offered on the top level within the field of vision, according to situation and context.
Emotive display concept
The EQE follows the EQS visually and in terms of interior displays. The dominant blue color scheme with a highlight in orange is immediately recognizable as "electric world". The Understated mode provides an emotive experience with minimalistic central display. And the optional three display surfaces can be transformed into a common color world in combination with the ambient lighting, the content while in this mode is reduced.
Driving assistance systems support in many driving situations
The latest generation of driving assistance systems includes numerous functions to support the driver. One new function is the microsleep warning from ATTENTION ASSIST (in conjunction with MBUX Hyperscreen). It analyzes the driver's eyelid movements using a camera in the driver display. The assistance display within the driver's display shows the operation of the driving assistance systems in a comprehensible full-screen view.
Interesting facts & figures
The new EQE: at a glance
Depending on the onboard equipment and configuration, WLTP operating ranges of up to
660 kilometers1 are possible.
The torque delivered to the wheels by the eATS (electric drivetrain) is checked 10,000 times per minute and adjusted if necessary. This enables a much quicker response in the later versions with 4MATIC than with mechanical all-wheel drive.
The EQE is available with rear-axle steering as an option. Two versions are optionally available with a steering angle of up to 4.5° and up to 10°. The turning circle is reduced from 41 to up to 35 feet with 10° rear-axle steering.
The electric motor on the rear axle has 2 windings with 3 phases each. This 6-phase design makes this permanently excited synchronous motor (PSM) particularly powerful.
DIGITAL LIGHT (optional extra) has a light module in each headlamp with three extremely bright LEDs whose light is refracted and directed with the help of 1.3 million micro mirrors. The resolution is therefore more than 2.6 million pixels per vehicle.
Mercedes me Charge has one of the densest charging networks, with over 530,000 charging points in 31 countries, including nearly 60,000 public places to charge in the USA.
With the MBUX Hyperscreen (optional extra), multiple displays merge seamlessly to create an impressive curved screen band over 56 inches wide. The area perceived by the occupants measures 2.6 sq. ft.
The large glass covering the MBUX Hyperscreen is curved in three dimensions in a molding process at temperatures of approx. 1202°F. This process allows a distortion-free view of the display unit across the entire width of the vehicle, irrespective of the radius of the glass cover.
A lithium-ion battery with 10 cell modules is installed in the EQE. In the case of the battery, a major step has been achieved in terms of the sustainability of the cell chemistry: the optimized active material consists of nickel, cobalt and manganese in a ratio of 8:1:1.
The optional driving sound of the EQE is interactive and reacts to a dozen different parameters such as the position of the accelerator pedal, speed or recuperation.
No.6 MOOD bittersweet is the name of the fragrance composed especially for the EQE, based on a dark chocolate aroma. It bears the number 6 because the first electric cars were added to the model range in 1906 in the form of the "Mercédès Electrique" vehicles.
To get to the most important applications of MBUX, the user has to scroll through 0 menu levels. Hence the term zero layer.
The display area of the optionally available larger head-up display corresponds to a screen with a diagonal of 77 inches. The imaging unit consists of a high-resolution matrix of 1.3 million individual mirrors.
The HEPA (High Efficiency Particulate Air) filter as part of the optional ENERGIZING AIR CONTROL Plus, with a volume of 9.82 dm³, cleans the incoming outside air at its very high filtration level. Up to 99.75 percent of particles of all sizes are separated. Around 21 ounces of activated charcoal are used to neutralize odors. The adsorption area is equivalent to about 150 football fields.
For haptic feedback during operation, a total of 12 actuators are located under the touchscreen surfaces of the MBUX Hyperscreen. If a finger touches certain spots there, they trigger a tangible vibration in the cover plate.
The EQE is also one of the first vehicles to be built with steel from Salzgitter AG, which is 100 percent recycled. This reduces the CO2 emissions in rolled steel production by more than 60 percent.
A coating on the glass cover simplifies cleaning of the MBUX Hyperscreen. The curved glass itself consists of particularly scratch-resistant aluminum silicate.
8 CPU cores, 24 GB RAM and 46.4 GB per second RAM memory bandwidth are included in the MBUX technical data.
A DC box with a charging capacity of up to 170 kW is fitted on board for (fast) charging via direct current. In 15 minutes it is possible to charge the EQE with up to 35.55 kWh – this corresponds to a range of up to 250 kilometers based on the WLTP range2.
The brightness of the MBUX Hyperscreen's screen is adjusted to the ambient conditions using the measurement data from 1 multifunction camera and an additional 1 light sensor.
With up to seven profiles, the display area of the MBUX Hyperscreen for the front passenger can be individualized.
"Hey Mercedes" supports 27 languages with Natural Language Understanding (NLU).
For high noise and vibration comfort, the electric drivetrains (eATS) have a special foam mat all around as an NVH cover. The lid of the inverter has a sandwich construction of 3 metal and plastic layers.
2 Data on power consumption and range are provisional and were determined internally in accordance with the "WLTP test procedure" certification method. Confirmed TÜV figures, EC type approval and certificate of conformity with official figures are not yet available. Differences between the stated figures and the official figures are possible.

Continuing the good genes of the EQS
The new EQE: the short version
Stuttgart. Just a few months after the introduction of the EQS, Mercedes-EQ is already presenting the next model based on the electric architecture developed specifically for electric vehicles, the new EQE. The sporty executive sedan offers all the essential functions of the EQS in a slightly more compact format. At market launch, the model range initially comprises two variants: the EQE 350 with 288 hp, as well as another model. Further versions will follow. Production of the EQE takes place at two locations of the Mercedes-Benz Cars global production network: at the German Mercedes-Benz plant in Bremen for the global market and at the German-Chinese joint venture BBAC in Beijing for the local market.
Compared to the luxury model EQS, the EQE is even more streamlined, with a slightly shorter wheelbase, shorter overhangs and more recessed flanks - it carries the concept of the executive sedan into the future. Sensual Purity is reflected in generously modeled surfaces, reduced joints and seamless transitions (seamless design). The overhangs and the front end are kept short, the rear provides the dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, the 19- to 21-inch wheels, together with a pronounced muscular shoulder section, give the EQE an athletic character.
In the outer dimensions (length/width/height: 196.6/77.2/59.5 inches), the EQE is comparable to the CLS. Like the latter, it has a fixed rear window and a trunk lid. The interior dimensions even clearly exceed those of today's E-Class (213 model series), i.e. the shoulder room in the front (plus 1 inches) or the interior length (plus 3 inches).
Unconventional interior design and high operating convenience
With the optionally available MBUX Hyperscreen, the entire instrument panel is a single, ultimate widescreen. This determines the aesthetics of the entire cockpit and interior. The high-resolution screens appear to merge seamlessly under the shared glass cover. The graphic appearance of their MBUX content is perfectly coordinated. The MBUX Hyperscreen is integrated into the instrument panel in minimalist fashion.
The vent band boasts a slim design that spans across the entire width at the top. These extreme proportions, together with the glass wave of the MBUX Hyperscreen, create the avant-garde architecture of the cockpit. The outer nozzles feature a turbine design. They play on the theme hyper analogue through the contrast between high-tech precision mechanics and digital, glass display world.
The latest MBUX generation, recently introduced in the EQS, is also on board the EQE. With adaptive software, the control and display concept completely adapts to its user and makes personalized suggestions for numerous infotainment, comfort and vehicle functions. With the zero-layer design, the user does not have to scroll through submenus or give voice commands. The most important applications are offered situationally and contextually on the top level in the field of view. In this way the EQE driver is relieved of certain operating steps.
Efficient drive system
The EQE 350 with 288 hp, plus a second model, will be launched first. Further versions will follow. All EQE models have an electric drivetrain (eATS) on the rear axle. The later versions with 4MATIC are also equipped with an eATS at the front axle. The electric motors are permanently excited synchronous motors (PSM). With the PSM, the rotor of the AC motor is fitted with permanent magnets and therefore does not need to be supplied with power. The advantages of this design include high power density, high efficiency and high power constancy. The motor on the rear axle is particularly powerful due to its six-phase design: it has two windings with three phases each.
In the EQE, the lithium-ion battery consists of ten modules and has a usable energy content of 90 kWh. The innovative battery management software, developed in-house, allows updates over the air (OTA). In this way, the energy management of the EQE remains up-to-date throughout the life cycle.
In the case of the battery, a major step has been achieved in terms of the sustainability of the cell chemistry: the optimized active material consists of nickel, cobalt and manganese in a ratio of 8:1:1. This reduces the cobalt content to less than ten percent. The continuous optimization of recyclability is part of Mercedes- Benz's holistic battery strategy.

ECO Assist also offers situation-optimized recuperation - deceleration is so strong or weak that it ultimately results in the most efficient driving style. If possible, recuperative deceleration is also used for vehicles detected ahead. This occurs until they come to a standstill, for example at traffic lights. The driver does not need to press the brake pedal for this – allowing for one-pedal driving.
Navigation with Electric Intelligence plans the fastest and most convenient route, including charging stops, based on numerous factors and reacts dynamically to traffic jams or a change in driving style, for example. This includes a visualization in the MBUX infotainment system as to whether the available battery capacity is sufficient to return to the starting point without charging.
High noise and vibration comfort, Sound Experiences as a contrast
As a sedan with a trunk lid, the EQE's concept is well equipped to offer a high level of NVH comfort (Noise, Vibration, Harshness) into account. Numerous measures contribute to this. In the electric drivetrains (eATS), the magnets are arranged inside the rotors in an NVH-optimized way (known as 'sheet metal cut'). In addition, the eATS have a special foam mat all around as an NVH cover. The inverter cover is a sandwich construction. The eATS are double-decoupled from the body via elastomeric bearings:
Highly effective spring/mass components provide continuous sound insulation from the crossmember under the windshield to the floor of the trunk. Acoustic foams are inserted into many carriers during body-in-white construction.
If desired, the ride in the EQE nevertheless becomes an acoustic experience: If the Burmester® surround sound system is on board, the EQE has the two soundscapes: Silver Waves and Vivid Flux. Silver Waves provides a rich and clean sound. Aimed at EV enthusiasts, Vivid Flux is crystalline, synthetic yet humanly warm. They can be selected or switched off as sound experiences on the central display. The additional soundscape Roaring Pulse can be activated as an over-the-air update. This sound experience is reminiscent of powerful machines, and is sonorous and extroverted.
Air suspension and rear-axle steering as options
The suspension of the new EQE, with four-link front suspension and multilink rear suspension, is closely related in design to the new S-Class. As an option, the EQE is available with AIRMATIC air suspension with ADS+ adaptive damping system. With rear-axle steering (optional extra), the EQE feels as maneuverable as a compact car in the city. The steering angle at the rear axle is up to ten degrees. The turning circle is reduced from 41 to 35 feet with rear-axle steering.
New vehicle functions can be activated via over-the-air technology (OTA). Available from launch: the additional sound experience "Roaring Pulse", two special driving modes for young drivers and service personnel, mini games, the highlight mode as well as DIGITAL LIGHT with projection function and DIGITAL LIGHT individualization. In Highlight mode the vehicle presents itself and its equipment highlights - this is activated by the "Hey Mercedes" voice assistant. In addition to the light animation "Digital Rain", DIGITAL LIGHT individualization includes other coming-home/leaving animations such as "Brand World". The OTA functions are available in the Mercedes me Store, and the range of features will be successively expanded.
Convenient charging in a large charging network
With the new Mercedes me Charge Plug & Charge function, the EQE can be charged even more conveniently at Plug & Charge-enabled public charging points: when the charging cable is plugged in, the charging process starts automatically; no further authentication by the customer is required. The vehicle and the charging station communicate directly via the charging cable.
Furthermore, Mercedes me Charge customers continue to benefit from the integrated payment function with automatic payment. The customer chooses the preferred payment method only once. Every charging process is then automatically debited – including charging abroad. The individual charging processes are clearly listed in a monthly invoice.
Mercedes me Charge is one of the largest charging networks worldwide: it currently has more than 530,000 AC and DC charging points in 31 countries, including nearly 60,000 public places to charge in the USA. By means of high-quality certificates of origin, Mercedes-Benz guarantees that energy from renewable energy sources is fed into the grid for charging current sourced via Mercedes me Charge.
High level of passive and active safety
The principles of Integral Safety, in particular accident safety, apply regardless of the platform. Like all other Mercedes-Benz models, the EQE therefore has a rigid passenger cell, special deformation zones and modern restraint systems with PRE-SAFE®.
The fact that the EQE is based on an all-electric architecture which opened up new design possibilities for its safety concept. It meant, for example, that a favorable location could be chosen for the installation of the battery, in a crash-protected area in the underbody. And because there is no large crankcase on board, the behavior in a frontal crash could be modeled even better. In addition to the standard crash tests, the car's performance in various additional load situations was verified and extensive component tests carried out at the Vehicle Safety Technology Centre (TFS).
The latest generation of driving assistance systems includes numerous features that further support the driver. One new function is the additional microsleep warning from ATTENTION ASSIST (in conjunction with MBUX Hyperscreen). It analyzes the driver's eyelid movements using a camera in the driver display. The assistance display within the driver's display shows the operation of the driving assistance systems in a comprehensible full-screen view.
Mercedes management on the EQE
"After the EQS, the EQE is already the second model on our platform for luxury- and premium-class electric vehicles. This speed of innovation shows the advantages of the scalable architecture: With the new EQE, we can quickly make the high-tech solutions of our electric flagship EQS available to a wider group of buyers. And our production flexibility reaches new heights with the EQE: at the Bremen plant, where the versions for the world market roll off the production line, four other models are already in production.”
Markus Schäfer, Member of the Board of Management of Daimler AG and COO of Mercedes-Benz Cars
"2021 is an extremely important year in our electric initiative: with the EQA, EQS, EQB and now EQE, we have celebrated four world premieres of fully electric passenger cars at Mercedes-Benz Cars. With its dynamic driving experience and comprehensive range of Connected Services, the EQE is a perfect fit for the desires of a modern generation of customers. We reconcile innovation and emotionality with sustainability: with Green Charging, we are actively contributing to the reduction of CO2 emissions. In addition, there are numerous intelligent functions that make everyday life easier for our customers. This includes Plug & Charge, for example - plug in and the EQE is charged without further authentication or registration."
Britta Seeger, Member of the Boards of Management of Daimler AG and Mercedes-Benz AG, responsible for Mercedes-Benz Cars Marketing and Sales
“The Mercedes EQE is the next all-purpose electric luxury sedan with the typical One-Bow-Signature Design creating fast lines and silhouette and through that a very aerodynamic and futuristic look. All of this makes the car more flamboyant and entertaining, more extraordinary and defines the next level of luxury for the Mercedes-EQ brand.”
Gorden Wagener, Chief Design Officer Daimler Group

Accelerated transformation from "Electric first" to "Electric only"
The new EQE: sustainability
Mercedes-Benz is setting the course for an all-electric future: by the end of the decade, the brand with the star will be ready to go fully electric - wherever market conditions permit. With this strategic step from "Electric first" to "Electric only", Mercedes-Benz is accelerating its transformation into an emission-free and software-driven future. In many areas, Mercedes is already thinking about tomorrow today: the new EQE is designed to be correspondingly sustainable. Resource-saving materials such as secondary steel are also used. Mercedes-Benz looks at the entire value chain, from development and the supplier network to its own production. Mercedes-Benz AG has had its climate protection targets confirmed by the Science Based Targets Initiative (SBTI). With these goals, the company supports the Paris Climate Accord.
Nine important building blocks of the transformation towards sustainable mobility.
- Electrified product portfolio
By 2022, Mercedes-Benz will offer battery electric vehicles (BEVs) in all segments in which the brand is represented. From 2025, all new vehicle architectures will be exclusively electric, and customers will be able to choose a fully electric alternative to each model. The company is significantly accelerating investments in research and development. Between 2022 and 2030, a total of more than 40 billion euros have been earmarked for investments in battery-electric vehicles. The faster expansion of the range of impressive electric vehicles will lead to a faster breakthrough of electromobility. In 2025, Mercedes-Benz will introduce three all-electric architectures: MB.EA, AMG.EA and VAN.EA.
- Transparent dialogue
Since 2005, Mercedes-Benz has been the first automotive company to subject its vehicles to the strict requirements of an environmental certificate in accordance with ISO guideline TR 14062. The TÜV-certified documentation is based on a comprehensive life-cycle assessment of the respective vehicle, in which every environmentally relevant detail is documented. The Group's sustainability report has provided detailed information on this topic every year since 2006. And the Daimler Sustainability Dialogue continues to bring together sustainability experts from various fields with Daimler representatives every year since 2008. Current and future sustainability issues are discussed in workshops, progress as well as deficits and risks are evaluated, and resulting needs for action are defined. In November 2020, the Daimler Sustainability Dialogue brought together over 200 representatives from business, science, politics, NGOs, associations, trade unions and local authorities in the digital space.
- Carbon-neutral production
Mercedes-Benz is working to prepare its global production network for the manufacture of fully electric vehicles. Starting next year, eight Mercedes-Benz electric vehicles will roll off the production lines at seven locations on three continents. By 2022, all passenger car and battery assembly plants operated by Mercedes- Benz AG will be converted to climate-neutral production. This also includes EQE production at the Bremen plant. To achieve climate-neutral production, the first step is to consistently reduce and, where possible, completely avoid emissions that are generated in Mercedes-Benz vehicle production and in the energy supply of the plants. The company relies on three strategic pillars for doing so: continuous increase in energy efficiency, use of green power and realization of a sustainable heat supply. Starting in 2022, all owned production plants of Mercedes-Benz AG around the world will obtain electricity exclusively from renewable sources. In addition, concrete CO2 measures are agreed with suppliers. Logistics are an essential part of this supply network: at the beginning of 2020, rail transport in Mercedes-Benz transport logistics were converted to a carbon-free energy supply in cooperation with Deutsche Bahn.
- Sustainable battery production
Local battery production is a major success factor in the strategic electric initiative of Mercedes-Benz AG – and a crucial element when it comes to being able to flexibly and efficiently serve the global demand for electric vehicles. Production plays a decisive role in Mercedes-Benz AG's understanding of sustainability. For example, the Mercedes-Benz Hedelfingen plant will ensure carbon-neutral production of battery systems as of 2022. In addition, Mercedes-Benz has agreed to purchase CO2-neutrally manufactured battery cells as part of strategic partnerships, starting with the EQS and followed by the EQE.
- Decarbonization of the supplier network
The EQE is one of the first vehicles with bodyshell components of 100 percent recycled steel from Salzgitter AG. This already reduces CO2 emissions for the semi-finished product by more than 60 percent. In general, the supplier network provides a considerable part of the value creation and is thus of crucial importance for the decarbonization goals. The majority of the suppliers accounting for around 90 percent of the annual procurement volume have already signed an Ambition Letter confirming their agreement to supply only parts from CO2-neutral production in the future. From 2039 at the latest, only production materials which have been produced on a carbon-neutral basis in all value creation stages will be allowed through the plant gates of Mercedes-Benz. A supplier declining to sign the Ambition Letter will not be eligible for new supply contracts.
- Raw materials from certified mining
Mercedes-Benz looks at the entire value chain, from development and the supplier network to its own production. Responsibly mined and processed raw materials provide the foundation for a sustainable Mercedes-Benz electric vehicle fleet. Mercedes-Benz has therefore had the complex supply chains of battery cell suppliers audited in accordance with OECD standards and will in future only purchase battery cells with cobalt and lithium from certified mining. In addition, Mercedes-Benz is making the "Standard for Responsible Mining" in the "Initiative for Responsible Mining Assurance" (IRMA) a key criterion for supplier decisions and contracts in raw material supply chains and will only work with suppliers who agree to these requirements.
- Resource-conserving materials
EQE components with a total weight of more than 165 lbs are made partly from resource-saving materials (recyclates and renewable raw materials). These include cable ducts made from recycled plastics, for example.
- Green power for on the move
With Mercedes me Charge, customers always charge green at every public charging station in the United States. It is ensured that for charged energy quantities corresponding amounts of green electricity are fed into the grid after the actual charging process and, in addition, incentives are created to invest in renewable energy plants. There is no basic fee for Mercedes me Charge for the first two years after the purchase of an EQE.
- Sustainable battery use
Mercedes-Benz takes a holistic approach to the battery life cycle: Re-Use, Remanufacture, Recycle. Once the traction batteries of the Mercedes-EQ fleet reach the end of their life on the road, it's far from over. Mercedes-Benz Energy, based in Kamenz, is a subsidiary of Mercedes-Benz AG responsible for the development of innovative energy storage solutions. By building stationary energy storage systems, electric car batteries can be connected to the grid. The spectrum for large-scale storage applications from Mercedes-Benz Energy ranges from peak load balancing and black start (power plant start-up independent of the power grid) to uninterruptible power supply (UPS). The company's focus is in particular on applications from the 2nd-life and replacement parts storage unit sector. Only then is it time for material recycling.
Avant-garde business sedan
The new EQE: the exterior design
The EQE features a sporty 'purpose design' with all the characteristic elements of Mercedes-EQ, one-bow lines and cab-forward design. Sensual Purity is reflected in generously modeled surfaces, reduced joints and seamless transitions (seamless design). The overhangs and the front end are kept short, the rear provides the dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, the 19- to 21- inch wheels, together with a pronounced muscular shoulder section, give the EQE an athletic character.
Compared to the luxury liner EQS, the EQE is even more streamlined, with a slightly shorter wheelbase, shorter overhangs and more recessed flanks - it carries the concept of the executive sedan into the future.
The sporty, low and slim front of the EQE forms a coupe-like silhouette with a bow (one bow) stretched tightly over the greenhouse. The A-pillar, which has been moved far forward, and the C-pillar at the rear create space for a generous passenger compartment. Unique in this segment is the cab-forward design: The overhangs and the front-end assembly are short, the rear forms a dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, the 19- to 21-inch wheels, together with a muscular shoulder section, give the EQE an athletic character.
The design philosophy of Sensual Purity is implemented with the clear, flowing design. Tense, sinewy surfaces emphasize the athleticism, and the claim of seamless design is confidently realized with reduced lines and flowing transitions. Aerodynamics and formal aesthetics are synergistically coordinated. The detailed design expresses innovation and exclusivity.
Black Panel front with Mercedes-Benz pattern on request
The front is combined into a 'Black Panel' unit. Innovative headlights and the deep black radiator grille (Black Panel) form the athletic face and simultaneously position the EQE as a member of the new Mercedes-EQ vehicle family. In addition to its unique look, there is also function behind the Black Panel surface: the various sensors of the driving assistance systems such as ultrasound, camera and radar are integrated. The concise daytime running light signet interprets the brand's characteristic flare. LED High Performance headlamps are standard, DIGITAL LIGHT is available as an optional extra.
The exclusive look of the Black Panel radiator grille with the central Mercedes star can be enhanced still further: in conjunction with AMG Line exterior, includes the Mercedes-Benz pattern, a three-dimensional star pattern. This references the original star of the Daimler-Motorengesellschaft company, which was registered as a trademark in 1911. The seamless design is reflected in the front-end design in particular. Examples include the reduced gap dimensions and overlapping hood. The latter does away with the traditional divide between hood and fenders.
Striking one-bow lines
The aerodynamic silhouette with frameless, coupe-like doors and the high, arched beltline are independent design elements in the profile. The outside mirrors sit on the beltline and are aerodynamically and aero- acoustically optimized. Chrome accents highlight design focal points like the one-bow lines of the window graphics. High-quality painted contrasting surfaces can be found in the lower area of the vehicle. Stone chip protection has been integrated into the chrome trim. The service flap for wiper fluid was integrated into the side of the left wing.
Light band with LED lamps in 3D helix design
The sporty, coupe-like rear carries a rear spoiler with a sharp spoiler lip. The large rear window, which extends downwards from the roof in a flowing contour, is a distinctive feature. For the first time, the components of the various aerials are hidden underneath, invisible from the outside. The trunk lid joins the windshield with a slight gradation and unobtrusively incorporates the additional brake light. The rear camera is hidden behind the star, protected from dirt. Another highlight at the rear are the innovatively designed LED lights: their insides have the shape of a curved and illuminated 3D helix. The EQE has a continuous light band at the rear - a distinguishing feature of Mercedes-EQ vehicles.

In the slipstream of the world champion
The new EQE: aerodynamics
For more than three decades, the aerodynamicists at Mercedes-Benz have been achieving top results. At present the EQS (V 297)1 with a Cd figure of 0.20, the A-Class Sedan (V 177) and the S-Class (V 223) with 0.22 are the world record-holders. The special simulation tools and the Mercedes-Benz aero-acoustics wind tunnel commissioned in 2013 make a decisive contribution to this. The EQE also received its fine- tuning there. It achieves a very good Cd figure thanks to its one-bow design and extensive aerodynamic measures.
After the EQS, it is the second Mercedes EQ to stand on the modular architecture for luxury- and premium- class electric vehicles. The electric sedan therefore shares many aerodynamic measures with its big brother - and is thus in the slipstream of the aerodynamics world champion. The Purpose design with a smooth underbody and mostly closed radiator shutter were a good starting point for flow optimization, although the EQE with shorter front and rear overhangs and standard steel suspension is at a slight conceptual disadvantage.
Mercedes also offers 19 and 20-inch aero-wheels which have been optimized in the wind-tunnel. Among them is a two-tone light-alloy wheel with an almost fully closed surface but visible high-sheen rim flange.
Behind the very good aerodynamic performance is a lot of detail work. The non-visible details in particular, for example on the underbody, were developed particularly intensively. Several thousand computational runs were performed in the virtual wind tunnel alone. Below are some details of the aero development:
- Aerodynamically favorable dimensional concept and tires with optimized geometry
- Aerodynamically optimized wheels
- Cooling air control system with innovative transverse louver makes extremely efficient use of the available installation space
- Continuous seals in the front area, i.e. between service flap, Black Panel and headlamps
- Streamlined design of the A-pillar
- Wheel spoilers at front and rear
- Elaborately harmonized underbody paneling in the rear axle area to take even greater advantage of the smooth underbody of the battery
- Distinctive spoiler lip on the trunk lid.
In an electric car without the usual level of powertrain noise, wind noise is particularly noticeable by the occupants. That's why the aeroacoustics behavior is particularly important. In this area too, the new EQE is one of the very best vehicles in its class.
Lots of fine-tuning in the details: in order to reduce or prevent low-frequency noises that can be perceived as reducing comfort, numerous cavities in the car body were filled with acoustically effective foam, for example.
It was also possible to reduce the high-frequency components of the wind noise in the EQE through improved seals on the door handles, the window supports and the outside mirrors. The aero acousticians paid special attention to the seals of the transitions between the six side windows. This concept is new to Mercedes-Benz vehicles and was first used in the EQS. Another contribution is made by the A-pillar with a specially shaped trim element at the transition to the windshield. In its development, both modern flow simulations and external noise measurements by means of a special microphone array in the wind tunnel were used. The A-pillar designed in this way not only improves the aeroacoustics, but is also important for a low cd figure and in keeping the windows free of dirt.
The Acoustic Comfort Package further enhances noise comfort. This includes acoustically effective laminated glass on the front side windows and additional insulation in the interior. On the panoramic roof, various wind deflectors, covers and seals with improved geometry ensure high noise comfort despite the large roof opening.
1 EQS 450+ (combined NEDC power consumption: 18.9-16.2 kWh/100 km; CO2 emissions: 0 g/km) with 19-inch AMG wheel/tyre combination and AMG Line exterior (available in the EU from the end of 2021) in the SPORT drive program. The power consumption (and information based thereon) has been determined on the basis of Commission Regulation (EC) 692/2008 according to NEDC and Commission Regulation (EU) 2017/1151 according to WLTP

Systematic digitalization and unusual materials
The new EQE: the interior design
The EQE is the new executive class sedan from Mercedes-EQ. With this completely new vehicle, the designers had the opportunity to take a completely new approach to the interior design as well. They used this freedom and, in addition to the MBUX Hyperscreen, relied on consistent digitalization and avant-garde design for many other elements.
Like the EQS, the EQE is based on a large electric platform from Mercedes-EQ. For the designers, this went hand in hand with the vision of systematic digitalization of the interior. The optionally available MBUX Hyperscreen implements this vision in a particularly impressive way: the entire instrument panel is one ultimate widescreen. This determines the aesthetics of the entire cockpit and interior. The real glass appears to drape itself three-dimensionally over the entire width of the vehicle like a wave - a unique feature in automotive construction to date.
The high-resolution screens merge seemingly seamlessly under the shared glass cover. The graphic appearance of their MBUX content is perfectly coordinated. The MBUX Hyperscreen is integrated into the instrument panel in minimalist fashion. Only a fine frame in silver shadow, a band of nozzles and a narrow leather ledge enclose the MBUX Hyperscreen. The leather ledge is reminiscent of the lower section of classic instrument panels.
The vent band spans across the entire width at the top and is very slim at the same time. These extreme proportions, together with the glass wave of the MBUX Hyperscreen, create the avant-garde architecture of the cockpit. For further details on the MBUX Hyperscreen, see separate chapter.
The dominant outer vents have a turbine design. They deliberately play on the theme of hyper analogue through the contrast between high-tech precision mechanics and digital, glass display world. The intricately designed turbine blades distribute the airflow efficiently.
The front section of the center console joins the instrument panel and stands freely in space. It is a visual reference to the new drive architecture – due to the electric powertrain, no transmission tunnel is necessary. Flowing leather surfaces with intricate seam dressings create a modern and luxurious impression in combination with the large-scale real wood blind. At the same time, there is plenty of practical storage space available.
The standard model without MBUX Hyperscreen has a slightly different center console. There is a soft armrest in the rear section. It is first visually interrupted before being transitioned into the floating central display. The smooth transition from 3D in the center console compartment to 2D on the touchscreen is seamless, i.e. without interrupting the glass look, and is unique.
Door trim modern, avant-garde and extremely reduced design
The vent band from the cockpit is visually continued in the driver's doors. A floating control cluster with integrated door opener and seat controls takes over the functional interpretation of formerly purely decorative elements. The door center panel develops in a sensual, dynamic movement from the vertical surface into the horizontal and thus integrates the armrest seamlessly. The front section of the armrest is designed as a metallic high-tech element that can be used as a free-floating grab and pull handle and contains the power window switch. In the dark, this floating, avant-garde aesthetic is particularly impressive thanks to an ambient light corona.
Seats: elaborately processed materials and perforations
Standard interior equipment includes the comfort seats. Despite their simplicity of design, they captivate with their sculptural beauty. Wrap-around surfaces in the side bolsters create the body support and stand in stark contrast to the seat center panel. It has a sophisticated seam pattern similar to a fan palm.
In combination with AMG Line interior, the EQE receives the sports seats. These are characterized by a slim and monolithic shape and act like integral seats. The seat surfaces are designed in such a way that they give the impression of draped-on leather covers. The technical term is "layering".
Common features of all leather seats are the dynamic graphic patterns with highly elaborate perforations. Here, too, you will find the hallmark Mercedes-EQ combination of the highest standards in materials, ambience and workmanship as well as state-of-the-art technology.
Color & trim: avant-garde and tradition for a special ambience
Avant-garde as well as traditional materials and colors give the interior a special atmosphere.
The modern delicate structure NEOTEX combines the look of nubuck leather and high-tech neoprene. It is found on the instrument panel, the armrest and the seats of the interior.
Six coordinated color combinations in the interior emphasize the generous feeling of space. The EQE is immersed in a progressive and luxurious color scheme of warm and cool tones. Colors such as Sable Brown/Neva Grey and Biscaya Blue/Black add the finishing touches to the soft and emotive design. The color rose gold, derived and evolved from the electric coil, emphasizes the design of the vent band and is used as a contrasting color.
The innovative trim parts make a key contribution to the aesthetics in the EQE. Three examples: a new trim in brown natural grain wood with grey printing of magnolia wood. The anthracite 3D relief-look trim, on the other hand, has fine metallic pigments. The different lighting situations in the vehicle subtly change the appearance and enhance the perceived value.
The laser-cut trim elements backlit with Mercedes-Benz pattern also create a special ambience. The star pattern is lasered into the plastic trim and is adaptively backlit. Innovative wood trim can also be selected, for example anthracite open-pore fine line lime wood.
A special welcome & goodbye scenario1 has been developed for the Mercedes-EQ models, which is also coordinated with the ambient lighting.
UX design: multiple display styles and modes to choose from
As with the EQS, the functional content and operating structure are adapted to electric driving. Visually, all graphics are designed in a new color scheme of blue/orange throughout. The classic cockpit display of the two round dials has been reinterpreted with a digital lightsaber in a glass lens. All content relevant to driving can be accessed between the round dials.
The "sport" display takes the form of a spatial power bar and conveys the relevant driving status (Drive, Accelerate, Charge) emotionally and impressively. The central object here is a "G-force puck", which dynamically moves in line with the acceleration forces.
The appearance of the screens can be individualized with three display styles (Understated, Sporty, Classic) and three modes (Navigation, Assistance, Service).
For a very calm interior impression, the Understated mode familiar from the S-Class has been adapted. In the EQE, the content of the displays is reduced as much as possible and coordinated with the color change of the ambient lighting in seven screen color worlds. In "Assistance" mode, important events such as lane changes or target distance control as well as the infrastructure and detected users on the road (cars, motorcycles, trucks) are displayed.

The EQE 350 as a harbinger of a model family
The new EQE: electric drive
The models available at launch are the EQE 350 with 288 hp, and a second model. Further versions will follow. The battery has ten modules with a usable energy content of around 90 kWh, and the range of up to 660 km according to WLTP is absolutely suitable for longer drives.
All EQE models have an electric drivetrain (eATS) on the rear axle. The later versions with 4MATIC also have an eATS on the front axle. In the 4MATIC models, the Torque Shift function ensures intelligent, continuously variable distribution of drive torque between the rear and front electric motors and thus the use of the most efficient eATS in each case. The modular powertrain concept ensures high overall performance and long range.
The electric motors on the front and rear axles are permanently excited synchronous motors (PSM). With the PSM, the rotor of the AC motor is fitted with permanent magnets and therefore does not need to be supplied with power. The magnets – and thus the rotor – follow the rotating alternating current field in the stator windings. In the EQE, Mercedes-Benz uses what is known as a pull-in winding for a particularly strong magnetic field. The engine is referred to as synchronous because the rotor turns at the same rate as the magnetic field of the stator. The frequency is adjusted in the power electronics converters to the speed requirements of the driver. The advantages of this design include high power density, high efficiency and high power constancy. The motor on the rear axle is particularly powerful due to its six-phase design: it has two windings with three phases each.
Cooling: sophisticated thermal concept for high load capacity
Consistently producing high performance and multiple accelerations without a drop in power characterizes the EQE's drive philosophy. This includes a sophisticated thermal concept with some special features. What is known as a water lance in the shaft of the rotor cools it from the inside. Other cooling elements in the cooling circuit are fins on the stator, a needle-shaped pin-fin structure on the inverter and a transmission oil cooler. This also brings more efficiency when driving in cooler temperatures, as the heat exchanger serves to heat the transmission oil and thus reduces friction in the transmission.
Intelligent recuperation: one-pedal driving to a standstill
The EQE offers several variants of energy recovery by means of recuperation: in this process, the high-voltage battery is charged by converting the mechanical rotary motion into electrical energy during overrun or braking mode. The driver can manually select the deceleration in three stages (D+, D, D-) as well as the gliding function via shift paddles behind the steering wheel. Also available: DAuto.
ECO Assist also offers situation-optimized recuperation - deceleration is so strong or weak that it ultimately results in the most efficient driving style. Recuperative deceleration is also used as far as possible for vehicles detected ahead until they come to a standstill, for example at traffic lights. The driver does not need to press the brake pedal for this – allowing for one-pedal driving.
Noise and vibration comfort: conceptual advantage plus extensive measures
As a sedan with a trunk lid, the EQE's concept is well equipped to offer a high level of NVH comfort. Numerous measures contribute to this:
The design of the electric powertrains (eATS) takes noise and vibration comfort (NVH - Noise, Vibration, Harshness) into account. The magnets are arranged inside the rotors in an NVH-optimized way (known as 'sheet metal cut'). This also reduces the use of rare earths. The shape of the winding, what is known as the stator tilt, also supports vibration comfort, especially at low speeds. In relation to the permanent magnets of the rotor, the coils of the stator are obliquely wound. Otherwise, what is known as cogging torque could occur. This would lead to slight but unpleasant vibrations when driving very slowly.
In addition, the eATS have a special foam mat all around as an NVH cover. The inverter cover has a sandwich construction of three metal and plastic layers. The eATS are doubly decoupled from the body via elastomeric bearings: at the front axle opposite a supporting frame and this against the body, at the rear axle with a subframe.
Highly effective spring/mass components provide continuous sound insulation from the crossmember under the windshield to the floor of the trunk. Acoustic foams are inserted into many carriers during body-in-white construction.
The electric refrigerant compressor has an NVH cover as encapsulation. In the rear-wheel-drive EQE, it is also soft-suspended, while in the 4MATIC models it is bolted directly to the front eATS. The operating strategy of the refrigerant compressor was designed for the highest possible noise and vibration comfort. Certain rpm ranges at which disturbing resonances may be audible when stationary or in a traffic jam are avoided or quickly passed through.

Fast laps in the hall
The new EQE under the magnifying glass: the eDrive test benches
One fast lap after another on the high-speed oval in Nardò in southern Italy, winding uphill and downhill stretches on the Swabian Jura or stop-and-go traffic for hours on the Stuttgart Weinsteige. And without ever leaving their workplaces in Untertürkheim, because they "drive a car without a car", Mercedes-Benz tests the drives of electric cars on eDrive test benches.
The electric drive of models in the fast-growing Mercedes-EQ family is being tested on a total of 13 test benches in Untertürkheim. Of these, seven are pure eATS test benches, where the power comes from a special direct current source, what is known as a battery simulation. On the six eDrive test benches, testing also includes the battery and the complete charging components of the vehicle. In addition, there are 13 test benches at the Nabern development site.
The test benches are connected to a monitoring room with computers. The most important measurement parameters for the test operation are visualized on one of the many monitoring screens. They tell the test bench driver in real time during the test whether everything is in order or whether a problem is imminent. Almost year round, the testing operation runs around the clock. Over the weekends, there is an on-call service; automatic shutdowns are communicated to the staff members responsible via instant messages or push messages on their smartphones. Remote access to the automation, diagnostic and measuring computers is possible.
The trial program: a whole car lifetime is simulated
All electric drivetrains (eATS) for all series are tested on the test benches. Both in terms of function and efficiency as well as durability. On the test benches, the eATS are coupled to load machines via the drive shafts installed in the vehicle - just like the drivetrain with a combustion engine and transmission on conventional test benches. At each rotational speed, they simulate different stresses on the e-drive.
The testing programs depict high-speed and road endurance runs. For this purpose, the test benches are programmed with data from real routes, topography and corresponding load conditions, for example acceleration, staying on the gas, kickdown or recuperation. For example, Nardò, the Swabian Jura and the Stuttgart Weinsteige take place in the hall. And for security reasons, without spectators.
With accelerated endurance runs, an entire car lifetime is simulated within a few months and with many megawatt hours of electricity. In this way, weak points can be detected in the shortest possible time and the drivelines optimized in good time before series production starts.
How long an eATS is tested on the test bench depends on the respective test program. The range extends from several weeks for testing individual functions to a whole year for an endurance run.

Powerful cell chemistry meets intelligent software
The new EQE: the traction battery1
The scalability of the battery system in the new Mercedes-EQ models of the luxury and premium class enables the realization of different range and performance variants. In the EQE, the lithium-ion battery consists of ten modules. The innovative battery management software, developed in-house, allows updates over the air (OTA). In this way, the energy management of the EQE remains up-to-date throughout the life cycle.
Battery development is a decisive factor in Mercedes-Benz's electrification strategy. After all, the battery is the heart of an electric car and makes a decisive contribution to, among other things, the range and thus the driving characteristics of the electric vehicle. With the EQS, a new generation of batteries with significantly higher energy density has been launched, from which the EQE now also benefits. The new batteries set standards in terms of performance, efficiency and charging capacity.
They also meet the high Mercedes requirements in terms of safety, durability and sustainability.
Mercedes-Benz issues a battery certificate for its high-voltage batteries, and thus a performance warranty for customers: 10 years or a mileage of 155,000 miles with a defined residual capacity.
Comprehensive battery expertise
The highly efficient batteries were developed entirely in-house by the team of experts at the Mercedes-Benz Battery Competence Center. The software for the intelligent management system was also developed and programmed in-house. The batteries are produced in the Hedelfingen section of the Stuttgart-Untertürkheim site.
A lithium-ion battery with ten cell modules is installed in the EQE. In the case of the battery, a major step has been achieved in terms of the sustainability of the cell chemistry: the optimized active material consists of nickel, cobalt and manganese in a ratio of 8:1:1. This reduces the cobalt content to less than ten percent. The continuous optimization of recyclability is part of Mercedes-Benz's holistic battery strategy. The aim is to be able to dispense entirely with materials such as cobalt through the use of innovative post-lithium-ion technologies.
Intelligent operating strategy for maximum range
The battery is integrated into the intelligent thermal management of the EQE. If the intelligent navigation with Electric Intelligence is activated, the battery is preheated or cooled as needed while driving to reach the best possible temperature for efficient charging at the charging point. The desired temperature range of the battery is achieved with the aid of the cooling circuit and a PTC (Positive Temperature Coefficient) booster heater integrated into it.
Complex protection concept for safety
As a matter of principle, Mercedes-Benz applies very high safety standards to all of its models. This means that, in many cases, internal Mercedes-Benz safety standards exceed legal requirements. The crash-related requirements in particular are aligned to the "Real Life Safety" philosophy. In the process, findings from internal accident research are incorporated into the development specifications. Alongside verification of crash behavior, all Mercedes-Benz vehicles undergo additional component tests at system level.
The battery sits in a crash-protected area in the underbody, embedded in the body shell structure including an extruded aluminum profile on the side. In extrusion, a heated block of metal is forced through dies and transformed into a continuous profile, which is then cut to fit. In this way, highly complex profiles can be produced that are precisely tailored to the requirements. The housing with energy absorbing structures at the front and side as well as a rigid, double-walled base plate provide additional protection for the modules. The test criteria include, among other things, the battery behavior under shock load and in the event of foreign object penetration. Overheating and overcharging were also simulated and tested. In addition, there is a separate, multi-level safety system for everyday operation. This includes, for example, temperature, voltage or insulation monitoring as a continuously monitoring safety system. If an error occurs, the battery is switched off.
Production: battery systems from Hedelfingen
The batteries for the Mercedes-EQ electric vehicles are supplied by the global battery production network with factories on three continents. Local battery production is a key success factor for Mercedes-Benz's electric initiative.
The battery systems for the EQE are produced in the Hedelfingen section at the Stuttgart-Untertürkheim site. Absolute precision is required in their manufacture. The battery systems consist of a variety of components, including ten cell modules and what is known as the EE compartment for the intelligent integration of the power electronics. It is assembled at the Mercedes-Benz site in Berlin.
The Mercedes-Benz Hedelfingen plant will have carbon-neutral production from 2022. The plant is a prime example of the transformation of production sites as part of the Mercedes-Benz Electric First strategy. The efficient and seamless integration of battery production alongside existing transmission production transforms Hedelfingen's traditional role as a site for conventional powertrain components into an important part of the company's global battery production network.
Mercedes-Benz has already agreed the CO2-neutral production of battery cells with two major suppliers. The supplier network accounts for a substantial share of value creation, and is therefore of decisive importance for the decarburization targets. Because of the higher energy requirements in the production of fully electric vehicles, the supplier network is a key component in achieving the climatic targets of Mercedes-Benz.

Always connected
The new EQE: the charging functions
Three charging programs are offered in the EQE - Standard, Home and Work. Within these, parameters such as departure time, air conditioning and maximum charge level can be preset. The Home and Work charging programs can be activated based on location. This means that they are switched on automatically as soon as the vehicle is parked at a charging point at the GPS positions stored in the system. The user is informed about this through MBUX.
The EQE also has these intelligent charging functions:
- ECO Charging is a take-it-easy program for the battery. Various measures reduce the battery load during charging and slow down the natural ageing process of the battery. For example, the maximum charging capacity is reduced, a charging limit of 80 percent is observed and charging is delayed based on the set departure time.
- With the charging interruptions function, the customer can specify time periods during which the AC charging processes are paused. Electricity costs can be saved as a result, for example.
- In Japan, bidirectional charging with the EQE will also be possible, i.e. charging in both directions. The CHAdeMO ("Charge de Move") charging standard there supports bidirectional charging. This is the prerequisite for the V2G (Vehicle-to-Grid) and V2H (Vehicle-to-Home) applications. Thus, for example, the EQE can serve as a temporary storage unit for electricity from the domestic photovoltaic system or supply the household with energy in the event of a failure of the public power grid.
A latest-generation charging system sits above the rear axle of the EQE. It can be used to charge the battery via the public power grid with single-phase or three-phase alternating current and an optional charging capacity of up to 22 kW in Europe. In addition, intelligent wallboxes from national partners are available to customers in the individual markets. Mercedes-Benz also offers an installation service for these wallboxes. This includes a preliminary check of the installation conditions, a detailed consultation and of course the installation.
A DC box with a charging capacity of up to 170 kW is fitted on board for (fast) charging via direct current. High charging currents can be maintained for a long time through temperature and charging management. Power for up to another 250 kilometers (WLTP) is recharged in just 15 minutes1.
The actual charging time depends on the battery size, the available infrastructure and the country-specific vehicle equipment. The charging socket is located at the rear right of the vehicle and is designed according to market requirements:
- Europe and the USA will receive the CCS system (Combined Charging System), which allows charging with direct and alternating current via the same connection.
- The vehicles intended for China (GB/T plug standard) on the other hand will also have a separate charging socket for DC charging, as will Japan (CHAdeMO standard). A twin charging socket is used here; it combines the separate AC and DC charging sockets under one charging flap.

Because the shortest route is not always the fastest
The new EQE: Navigation with Electric Intelligence
As far as Navigation with Electric Intelligence is concerned, the name says it all. Because it plans the fastest and most convenient route, including charging stops, based on numerous factors and reacts dynamically to traffic jams or a change in driving style, for example. With the EQE, Navigation with Electric Intelligence is particularly advanced, for example, it is able to calculate estimated charging costs per charging stop. Furthermore, the customer can edit the planned routes individually by adding in preferred charging stations along the route or excluding proposed charging stations.
While a conventional range calculator relies on past data, the Navigation with Electric Intelligence system looks into the future. The energy demand is computed for the calculation of the route. The topography, route, ambient temperature, speed, heating and cooling requirements are all taken into account. Further factors include the traffic situation along the planned route, as well as the available charging stations that can be found there, their capacity and payment functions. Calculation takes place in the Cloud and is combined with on-board data.
The customer does not necessarily always have to take on a full charge, but will be given a specific recommendation as to the required charging time at the charging station. The charging station stops will be planned in the way that provides the maximum benefit for the overall traveling time: under certain circumstances, two short charging stops with a higher charging power can be more advantageous than charging once for a long time. In addition, Navigation with Electric Intelligence automatically adjusts the vehicle's charging settings and optimizes them for fast charging along the route.
MBUX displays whether the available battery capacity is sufficient to return to the starting point without charging. Charging stations along the route that have been added manually are given preference in the route calculation. Proposed charging stations can be excluded. The estimated charging costs per charging stop are calculated.
If there is a risk of not reaching the destination or the charging station with the selected settings, Active Range Monitoring issues the prompt to activate ECO driving functions. In addition, the driving speed for reaching the next charging station or the destination is calculated and displayed in the speedometer. Under the menu item "Range", the EQE driver can switch off various energy consumers to increase the range and activate the ECO driving functions to support a more efficient driving style.

Further reducing the carbon footprint with green power
The new EQE: Mercedes me Charge
With Mercedes me Charge, customers can charge green at every public charging station throughout the United States. High-quality guarantees of origin ensure that as much green power from renewable energies is fed into the grid as is withdrawn via Mercedes me Charge. In the first two years after the purchase of an EQE, there is no basic charge for Mercedes me Charge and thus Green Charging for customers. With the new Plug & Charge function, the EQE can be conveniently charged.
Mercedes me Charge is one of the largest charging networks worldwide: it currently has more than 530,000 AC and DC charging points in 31 countries, and nearly 60,000 public places to charge in the USA. At selected charging stations, such as Electrify America’s fast charging network, green power is already being offered. Mercedes me Charge is now significantly expanding this opportunity to further reduce the carbon footprint: with Mercedes me Charge, customers are able to charge green at every public charging station throughout the United States. In addition, the functionality of Mercedes me Charge in MBUX will be expanded to include functions such as filtering and forecasting the availability of charging stations.
How Green Charging works: to promote the use of electricity from renewable energies, Mercedes-Benz uses guarantees of origin to 'green' the charging process, whose quality is defined by an eco power label. This ensures that an equivalent amount of electricity from renewable resources is fed into the grid to compensate for the charging of an electric vehicle. Amounts of energy used for charging are thus offset with green power after the actual charging process, also creating incentives to invest in renewable energy plants. In the first two years after the purchase of an EQE, there is a fee for Mercedes me Charge. The prices of the charging operator may vary. Green charging and driving become tangible with MBUX.
Plug & Charge - simpler and more convenient charging
With the new Mercedes me Charge Plug & Charge function, the EQE can be charged even more conveniently at Plug & Charge-enabled public charging points: when the charging cable is plugged in, the charging process starts automatically; no further authentication by the customer is required. The vehicle and the charging station communicate directly via the charging cable.
Furthermore, Mercedes me Charge customers continue to benefit from the integrated payment function with automatic payment. The customer is able to choose their preferred payment method once, then every charging process is then automatically debited – including charging abroad. The individual charging processes are clearly listed in a monthly invoice.
Whether a charging station is Plug & Charge-compatible can be seen by the charging station details shown on the central display of the EQE and in the Mercedes me App. It is also possible to search for specific, suitable charging stations. This convenient authentication method will initially be available at the Electrify America fast charging stations throughout the United States. Plug & Charge is the fourth way to access charging points, alongside enabling via MBUX on the vehicle's media display, the Mercedes me App and the Mercedes me Charge card.
Mercedes me App: easy operation on smartphone and tablet
The Mercedes me App offers many improved and new functions since the last revision. These include a filter option that allows the charging points to be sorted according to criteria such as availability or charging capacity. The likelihood over the course of the day of a particular charging point being busy is also determined and displayed on the basis of a probability calculation.

High levels of driving dynamics and handling
The new EQE: the suspension
The suspension of the new EQE, with four-link front suspension and multilink rear suspension, is closely related in design to the new S-Class. Rear-axle steering with a steering angle of up to 10° is available as an option for ease of maneuverability in town and agility out of town. Optionally, the EQE is also available with AIRMATIC air suspension with ADS+ adaptive damping system.
The EQE has the proven four-link front suspension. Its multilink rear suspension is designed to integrate the rear-axle steering. The suspension subframe carriers and the elastomeric bearings of the rear axle struts were improved in terms of NVH and driving characteristics by conducting extensive simulations and driving tests.
The optional AIRMATIC air suspension responds particularly perceptively, as it combines air suspension bellows with adaptive ADS+ dampers whose characteristics can be fully automatically varied at each individual wheel, in both the compression and rebound stages. While driving, a sophisticated sensor system and algorithms set the dampers according to the quality of the road to ensure that, for example, driving over a bump with just one wheel is not transmitted to the entire axle and the interior. Spring and damper are combined in one strut on the front axle.
This level control is part of AIRMATIC. It keeps the ground clearance constant irrespective of the vehicle load, but also makes changes when needed. By way of example, in the SPORT program the vehicle body is lowered by 1 inch at high speeds above 75 mph to reduce aerodynamic drag and increase handling stability. If the vehicle drops below 50 mph, the body level returns to the initial position. Up to 25 mph the body can be raised by 1 inch at the touch of a button, above 30 mph it is automatically lowered back to normal level.
As maneuverable as a compact car: both axles can do the steering
Thanks to rear-axle steering (optional extra), the EQE feels as maneuverable as a compact car in the city. The steering angle at the rear axle is up to ten degrees. The turning circle is reduced from 41 to 35 feet with rear- axle steering.
The interaction between front-axle and rear-axle steering has been designed to achieve agile response with low steering effort in city and country road driving, but at the same time very high stability. This results in i.e. small side-slip angles and a high level of yaw suppression. At high speeds the focus is more on stability, though without compromising precision and responsiveness. This added value is achieved by integrated actuation of the steering and brakes (ESP®), and considerably improves handling safety as a result.
Depending on the tires selected, customers can choose between two versions of the optional rear-axle steering with a maximum steering angle of 4.5° and 10°.
DYNAMIC SELECT: the EQE drives the way the driver wants it to drive
The driver can individually modify the characteristics of the powertrain, ESP®, suspension and steering. The selection is made using a control at the lower end of the central display. The default setting is the COMFORT drive program, with SPORT, ECO and INDIVIDUAL available as alternatives. The selection is acknowledged by acoustic and visual feedback. The desired drive program is shown as the status and depicted in the central display.

Zero-layer design: the most important things are now only one click away
The new EQE: MBUX (Mercedes-Benz User Experience)
MBUX (Mercedes-Benz User Experience) has radically simplified the operation of a Mercedes-Benz. Introduced in 2018 in the current A-Class, more than 1.8 million Mercedes-Benz passenger cars are now on the road with it, and the Vans division is also relying on MBUX. The second generation of this adaptive system was launched in the new S-Class, followed by the next big step with the EQS. With adaptive software, the control and display concept completely adapts to its user and makes personalized suggestions for numerous infotainment, comfort and vehicle functions. With the zero-layer design, the user does not have to scroll through submenus or give voice commands. The most important applications are offered situationally and contextually on the top level in the field of view. This relieves the EQE driver of numerous operating steps. Mercedes-Benz has integrated numerous music streaming providers holistically into the MBUX Infotainment system with the "Online Music" service.
Infotainment systems offer numerous and extensive functions. Several operating steps are often required to control them. In order to reduce these interactive steps even further, with the aid of artificial intelligence Mercedes-Benz has developed a user interface with context-sensitive awareness.
The MBUX system proactively displays the right functions at the right time for the user, supported by artificial intelligence. The context-sensitive awareness is constantly optimized, both by changes in the surroundings and by user behavior. The 'zero layer' offers the user dynamic, aggregated content from the entire MBUX system, and thus the associated services, on the uppermost level of the MBUX information architecture.
Mercedes-Benz has investigated the usage behavior of the first MBUX generation. Most of the use cases fall within the Navigation, Radio/Media and Phone categories. The navigation application with its full range of functions is therefore always in the center of the visual display unit.
Over 20 other functions - from ENERGIZING COMFORT to birthday reminders and suggestions for the to-do list - are automatically offered with the help of artificial intelligence when they are relevant to the customer. The developers have internally christened these suggestion modules, which are displayed on the zero-layer interface, "Magic Modules".
Here are three representative use cases. The user can accept or reject the respective suggestion with just one click:
- When approaching a charging station that is enabled for Plug & Charge, the Magic Module 'Charging' automatically appears. The driver can then start charging immediately.
- If someone always calls one particular friend on the way home on Tuesday evenings, in future they will always receive a suggestion regarding this particular call on this day of the week and at this time. A business card appears with their contact information and – if it is stored – their photo. All the suggestions from MBUX are coupled with the profile of the user. If someone else drives the EQE on a Tuesday evening, this recommendation will not be made - or another one will be made, depending on the habits of the other user.
- If the user regularly switches on the heating of the steering wheel in addition to the seat heating, for example, this is suggested to them as soon as they activate the seat heating.
The EQE has the latest MBUX generation. The impressive MBUX Hyperscreen is available as an option. There, the front passenger also has their own screen.
Face recognition with cameras in the driver display is used for a wide range of assistance and comfort functions. These include biometric authentication, ATTENTION ASSIST drowsiness warning and adjusting the outside mirrors to the pre-set position. In combination with the standard Display Package or the MBUX Hyperscreen, a fingerprint scanner for driver authentication is on board.
Hey Mercedes: the voice assistant can now do even more
Compared with the previous MBUX generation, the "Hey Mercedes" voice assistant is even more capable of dialogue and learning by activating online services in the Mercedes me App. Moreover, certain actions can be performed even without the activation keyword "Hey Mercedes". These include taking a telephone call. "Hey Mercedes" now also explains vehicle functions, and can help for example when asked how to connect a smartphone by Bluetooth or where the first-aid kit can be found. "Hey Mercedes" is now also able to recognize vehicle occupants by their voices. Once the individual characteristics of the voice have been learned, this can be used to access personal data and functions by activating a profile.
Online music: music streaming with millions of songs to choose from
With the "Online Music" service, Mercedes-Benz has now fully integrated the major music streaming services - Spotify, Amazon Music and recently also Apple Music - into the MBUX infotainment system. MBUX enables access to the personal user profile at the linked music providers. This allows customers to seamlessly access their favorite songs and playlists and discover millions of songs as well as curated playlists. Operation is intuitive using the MBUX voice assistant via "Hey Mercedes" and via touch controls on the steering wheel or central display.
Personalization is simple and convenient
A personal profile can be created directly in EQE and synchronized with existing profile data of the Mercedes me account. By scanning a QR code with the Mercedes me App, the vehicle is automatically connected to the Mercedes me account.
Personal preferences such as a favorite radio station and preselected settings can be transferred to any seat via the personal Mercedes me profile. Up to seven different profiles with a total of around 800 parameters are possible in the vehicle. As the profiles are stored in the Cloud as part of Mercedes me, the profiles can also be used in other Mercedes-Benz vehicles with the new MBUX generation.
In addition to the classic entry of a PIN, a special authentication procedure ensures a high level of security. Fingerprint, face and voice recognition are combined. This allows access to individual settings or verification of digital payment processes from the vehicle.
