@Belda our usage profile pretty much matches what you are planning most of the time. Current tank of fuel shows 316 miles with 64% left, an average of just over 85mpg. There are a few trips beyond electric range in there or it would be much better. We’ve had over 1000 miles out of a tank before.....and it’s not a big tank.
We charge it at home after every trip and find we generally drive more economically than we used to with our previous cars. Wafting along in silence is quite addictive, but once you are on a longer trip and using the ICE, the performance can be quite tempting too.
Pretty sure the battery was not changed during the production of the car - just the 6.2kWh. If a facelift C appears it’ll likely get the same power train etc that the new E has, with the 12kWh battery.
Our experience with the range matches
@Dodgy lucky to get 7 or 8 miles in winter, summer about 12 to 14 depending on journey and driving style, as well as if you use E mode and run the battery down flat rather than leaving it in hybrid where it’ll always retain around 16% or so but switch to ICE.
Worst mpg so far was a round trip of about 300 miles, mostly motorway, starting on full charge. Gave low 50s IIRC
