Figures for June.
It was 4.6 for most of the month but it just edged to 4.7 in the last few days.

Mine for June. As the mileage suggests, nearly all motorway, all over the country

This is with a mix of motorway, A roads, B roads and town driving.
I bought the car at the beginning of July with 11500 miles and have been driving pretty much the same way I did in my 2012 C Class Merc C220 diesel automatic which returned 50mpg.
I rarely use aircon except to clear the windscreen and keep the HVAC fan turned down to 2 or 3
I try to stick to speed limits so drive 65 to 70mph on motorways, 55 to 60 on A roads, whatever is comfortable on B roads and whatever the limit is in town.
When I got the car I messed about with KERS a couple of times but the majority of the time left it in default 2.
I also use cruise control a lot but I suspect it is not especially economical as it slows down and speeds up a lot more than I would.
I've seen people claiming using KERS3 makes a big difference which confuses me as the brakes appear to be mostly regen anyway but will reset the trip and try again driving the same way except with KERS set to 3.
This photo was taken after driving around 170 miles in one day and the car was charged to 100% before I left so giving a theoretical range of 215 miles.

Overall though I am happy with the car.

You’re not the only one confused, key to good economy is not having to slow down/speed up in the first place, KERS only helps to recoup a fraction of the energy needed.

What seems to make a real difference with everything else the same is rim size, smaller 16” are more efficient.

I watched a video earlier where a guy was claiming 19% difference when switching from KERS1 to KERS3 but failed to mention the first trip was done in winter and the second in summer.

Edit, I had another look and this is incorrect. Someone in the comments mentioned 4deg C but the temp showing on the dash for the first test was 13C and the second 16C so not such a big difference but I'm still not convinced the test was accurate.

So has anyone been able to figure out if using KER3 is any better than smooth gradual braking?
When I watch the HV current it is obvious that most of the braking is regen anyway.

Last day of the month again.
Hit an all time high for me with an average of 4.8 miles/kWh.

It was 4.7 for me yesterday but I did a 40 mile journey today and it clicked up a notch.
 
As good as it gets:

Did a bit of experimenting, the only way I can improve these figures is to slow down drastically but as I generally already drive about 10% below speed limits (no motorway journeys), I don’t want to become the infamous ‘Sunday driver’…
