According to Mercedes, the EQS can get range "of over 600 kilometers (according to WLTP)". That would be around 372 miles.

However, Mercedes has yet to release the official range numbers for the EQS 450+ and EQS 580 4MATIC

Long-range driving fun
The new EQS SUV: electric drive

With a range of over 600 kilometers (according to WLTP)1 and an output of up to 536 hp, the EQS SUV meets the requirements of a luxury SUV in terms of the drive system. All EQS SUVs have an electric drive train (eATS) on the rear axle, and the 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.

The modular drive concept allows a wide range of maximum total drive outputs from 355 to 536 hp. Depending on the vehicle equipment and configuration, WLTP ranges of over 600 kilometers are possible.

The electric motors on the front and rear axles are permanently excited synchronous motors (PSM). On a 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 EQS SUV, Mercedes-Benz uses a pull-in winding for a particularly strong magnetic field. The motor 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 inverters 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 high performance with multiple accelerations without a drop in power characterize the drive philosophy of the EQS SUV. This includes a sophisticated thermal concept with some unique features. A rotor cooling system 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 heat exchanger. This additionally brings more efficiency during cold driving, as it contributes to the heating of the transmission oil at the start of the drive and thus reduces friction in the transmission.

Intelligent energy recovery: One-pedal driving to a standstill

The EQS SUV offers several variants of energy recovery by means of regeneration. The driver can manually select the deceleration in three levels D+ (sailing), D (standard regeneration), D- (strong regeneration) via paddle shifters behind the steering wheel.

On top of this there is DAuto: In regeneration level DAuto, the ECO Assistant offers situation-adapted regeneration - it operates in gliding mode or decelerates in such a way that the bottom line is the most efficient and comfortable driving style possible. The driver is shown in the instrument cluster and, if applicable, on the head-up display when it is advisable to take the foot off the accelerator pedal due to an upcoming event. If the indication is followed, the vehicle is decelerated with the greatest possible energy recovery rate until it comes to a standstill if there is another vehicle ahead, for example. The driver does not need to press the brake pedal for this - literally one-pedal driving. Up to 5 m/s² deceleration can be achieved, 3 m/s² of which is due to energy recovery.
