Hi after over 6mths ownership I am finally taking my EQC on its first long journey of about 400km mainly peage. There are 2 Ionity stations on the route which I shall use to recharge as advised by the navigation in Mercedes’ me. Not yet programmed the destination direct into the car. The location of the chargers is quite good in terms of the journey but the last one will need to cover the non peage portion to my destination and leave enough for me to locate local chargers as the hotel does not have any facility ( hotels need to wake up to the need for charging!) but my destination seems well served.
To enable me to check calculations and judge the SOC needed can someone give any idea of the sort of consumption they see at 70 or 80 on motorway stretches? I know temps and headwind are variables but I am wondering what return is likely. I have taken a 100 k trip on a mixed route which incls about 40k of 130, 40 at 110 and the rest is 90 and the consumption is not bad in the normal range but I cannot pinpoint what she was using at the 130.
Overall with all the mixed driving I do mainly on our local roads and often very short trips my global consumption since I took delivery of the car is 25kwh/100km or 4km per kw. Now with the warmer weather I am generally seeing returns on individual trips of around 22kwh/100km.
Should I assume a higher consumption for 130km and if so what ballpark figure seems to be the norm?
Thanks.

I've just got back from my first roadtrip after almost a years ownership. 2200 km in total, most of it cruising on uncongested motorways at 110 km/hr (that's as fast as they'll let us go here, and the limit is strictly enforced). Total average for the trip was 20.1 kWh/100km. 3 adults on board and a boot full of luggage, aircon and seat vents on throughout.

Longest run was Karuah to Coffs Harbour - 331 km with 43km in reserve on arrival.

Charging peaked at 109kW and took the battery from 11% to 71% in 31 minutes. Average charge speed for that session was a very impressive 96kW.

Thanks for responding 110k was economical in the e class too. I think using 25kwh/100 may not be too far off the mark. I will report back I leave on the 7th May. Be interesting to see the charge speeds too. I plugged her in at Lidl today and did get the full 11kw on an AC charger so hopefully the rapids will be rapid.

Hi Parkwood, slightly UK centric feedback but on a 160m trip at Easter I was getting 2.6m/KWh compared to 2.1m/kWh in December on the same journey up the M1.
Both instances the car was well loaded and I travelled at an ave 75mph
Biggest difference being more use of the heating in December.
iirc on both journeys from a 100% SOC, December I had an estimated 190m range and Easter was 216m. Car has still only done <3k miles though so not sure if that affects range calc or if it’s only ever based on the preceding 300m or so.

Sat having breakfast before leaving car is at 100% first time ever since I had it! The GOM(gauge o meter or guess o meter as some call it) says range is 371km or 230 miles. Yesterday in a balmy 20degs I managed 19kwh/100km so really good consumption despite overtaking fast on 3 occasions. I shall report back on the efficiency achieved today on the peage at 130km. Looking forward to the trip but still a little anxious about how to make the Ionity chargers work am sure it will all be ok but first time for anything is always slightly daunting😉

Safely at my destination after an extremely clam and pleasant journey. The two Ionity charge stations were available in both locations and both worked a treat with the mercedes me charge. I was only charged .29 centimes a minute too. In both caes I stopped no longer than I would have done in any event in any car and in the first instance was back up to 97% SOC and the 2nd 100% and the car is now in the hotel car park with 81% so I may not need to charge before the return journey when I will pick up the Ionity again.
One section was totally peage at 130km and according to the Mercedes’ eco app consumption was 25kwh/100km over 180km with a temp of 19.1C. There seemed to be a bit of a headwind blowing too.
According to mercedes me trip meter over the entire trip of 387.4 km taking 4hrs 18 at an av speed of 90km Consumption was 22.8km the trip being topped and tailed with come non motorway sections.
Overall I am delighted with the efficiency and feel quite confident now about making the longer journeys. Having the 25kwh for motorway use will also help with planning though this will of course be reduced in colder temps.

Good access to decent fast chargers is probably a big reassurance.
UK is still hit and miss in my experience. I’ve pulled into a service station and had immediate access to a 150kwh charger - luck more than planning as there was only one charger at this service station, and there was a queue when I returned from the shop & taking the dog to the ‘facilities’ but I think it added over 65 miles to my range in the short time I was there. Other times I’ve pulled in at services with 5+ chargers only to be at the back of queue of 3-4 cars already.

At each of the stops there were several units 5 at one 7 at the other and only1 other car at the 2nd stop though that actually changed so in effect 2 others. 2nd stop was lunchtime too. Charge speeds were both below the 110max and both dropped as the SOC became higher but that is normal both times the car reached the SOC range in the stated time at commencement. Max charge was 80kw plus I think but I forgot to note it but it dropped steadily. Have identified a 50kw charger close to the hotel which also accepts credit cards if needed. Seems that is more the norm here it has a max 17.50 euro charge cost and is 3.50 min. I think for UK based owners France may be better than they are used to.

Any more details on the re-charging stops? What battery %age did you arrive with at each Ionity, and how long did the two charges take?
Left home with 100% and after a journey of mixed 90km route and then 130km motorway arr at the first charger after 124 km average power consumption of 23kwh/100km temp 14.3C (data from the eco app) 64% SOC. The car took 33mins to add 35% (29kwh) and reached 99% cost 9euro 86 centime.
The next stage was 180km all at 130k temp had risen to 19.1deg C efficiency was 25kwh/100km arrived with 42% SOC. The car took 42mins to charge back to 100% a charge of 58% 48kwh cost 12.47 euro. We arrived with 81% at our destination which was mainly a mix of 90 and 110k roads.
On both occasions the Ionity chargers were delivering below 90kw on initial charge and the rate dropped as the charge progressed.
The eco app has nagged about the car being charged to 100% and also about being parked at over 90% (that was for just a few minutes too!). The car has sat for 2 days at 81% supposedly not ideal but given the price of the thing I do not expect to have to mollycoddle it all the time! It spends most of its life in the good range and it seems hard to think this small trip could cause the battery to deteriorate. I lease so am reasonably happy if the battery is deteriorating it will not cause me too much problem before the car goes and is replaced ( I say hopefully!)
