stretching the range is a great EV meta game, does no one else play
I got a ~15% range increase in Feb putting EV tyres back on instead of sports tyre I bought by mistake when I down sized, who knew that all PZ4s are not the same.... seeing 36-39 since doing so, maybe I will finally get in the 40s with regularity in the warmer times only done so once or twice before changing wheel size but 49 is a strong ask, that's ~3.3 miles per Kw excluding charging loss.
35 miles seems reasonable from 14.9 usable battery if you are in single digit temps, it's a 2 tonne SUV, check all EVs of similar size and weight and you'll see that over 3 mile per kw is a bit of a pipe dream in low temps, even in normal temps, you're lucky not to be under 2.
Have they given more battery on newer MY24 Volvo as they do claim 51/62 city which is very strong, upto 4m/kw based on the old usable, if so that is a massive step up in efficiency, would need improved motors or battery really I'd have though, specs now say 19Kwh battery too, rounding from 18.8 or new battery?
