Is this range right?
Discussion
Never had an EV before, but thinking about it...
I tried out an EQC and with a variety of driving it averaged 2.0 miles per kwh.
With 80kwh usable and day-to-day only working within the 10% - 80% range, that only gives 56kwh. So 112 miles range day-to-day. I often drive 120-150 miles in a day and don't have time to stop in the middle.
My C63 only averages 14mpg and I can still get 200 miles on a tank.
Am I missing something or am I right to feel very disappointed?

Massive brick = very bad aero
You must have been absolutely caning it

. And I can get a staggering 20mpg on a long run. fly said:

Aside from the brick aero comments, I find that my EV (Solterra, 64kWh) does quite poor consumption for the first few miles on colder mornings if it's not been conditioned with a preset leave time. As a result I was getting similar range numbers (125 miles) to you when I was doing 3 mile journeys then stopping for an hour and then another short journey. Made even worse by using full cabin hetaing.I tried out an EQC and with a variety of driving it averaged 2.0 miles per kwh.

When the journeys were a touch longer - say 30 miles, the usable range almost doubled.
TL;DR: If you want to do distance leave your car on charge the night before and condition/pre-heat it using your house electric or accept that the initial range/usage will take a hammering until the battery and cabin is up to operating temp.

Why are you only working within the 10-80% range?
Is the range in your C63 only using 70% of its tank?
Yes this isn't really needed as I am sure most EVs now already operate like this and its presented to the driver as 0-100% already. Is the range in your C63 only using 70% of its tank?
for reference EQC has an 85 kWh nominal battery pack size with 80 kWh being usable so base your calculation on the usable pack size of 80.

I'm wondering how absolute the "no time to stop in the middle" is? If a 20-minute coffee/comfort stop is possible, you might get (in the real world) between 20 and 50 kWh with a suitable fast charger/car combination. 40 miles more range, even in the worst-case scenario.
Requires a different car model, though. EQS?
2 miles per kwh is staggeringly low for an EV. I've no idea if it's normal for that particular model, by my 2017 Nisan Leaf does 4.2 according to its average readout at the moment, and that's including the last winter's use. Seems like big SUVs make poor EVs. I'd suggest getting a car shaped car if you want an EV with the range you require.

Don't think it is far wrong...spritmonitor.de has data for the EQC and the average is 30.2 kWh/100km or 482 Wh/mi. So just over 2 miles for the kWh.That is the average as well. The max value goes well in to the 1.x miles per kWh.
It's just a juicy EV.
I’m picking up an EQC in the next week or so as the £9k Mercedes contribution & £500 towards a charger made it an attractive proposition.
My daily commute is a 50 mile cross country round trip and I will be plugging in at home via a 7kw charger so hopefully will suit my needs.
I was hoping for something around 2.4 miles per kw.

That's piss poor. Our etron 55, with more weight and similar performance, has average 2.5 miles/kwh over the past 18 months and 2 winters we've had it. Did a 20 mile trip today of mixed driving and it returned 2.7 miles/kWh without pre-conditioning and at 8 degrees.That is the average as well. The max value goes well in to the 1.x miles per kWh.

Why is it shocking that an SUV (regardless of fuel type) is less efficient on fuel than a small car? raspy said:

It's shocking because one of the major points about the move to EV is supposed to be efficiency, and yet here we are producing laughably inefficient cars. I'm not shocked that an SUV is inefficient, I'm shocked that we're producing SUV EVs at all. We should be taking the opportunity to divest ourselves of these unnecessarily inefficient vehicles from our roads as far as possible. But yeah, I know, Tanya wants one to drive the dustbin lids to school in and look down on lesser mummies, so here we are.
It's called consumer choice. Life would be really boring if we were all assigned a Nissan Leaf as the only choice of vehicle. Thank God we aren't living in a dictatorship. I don't think your sums are too far wrong. Some EVs are more equal than others.
While the Merc (and eTron and Taycan and many others) are getting 2.0-2.5 miles/kWh, the Tesla, EV6, ioniq 5 etc could be seeing 4+ in the same conditions.
Definitely try some other models and see if the sums look better for your needs.
