It's +- the same as upgraded just the battery... So during summer I'm able to get under 170Wh/km even I'm not trying to hypermile, just normal driving.. The overall whole year average consumption I have is +-206Wh/km (of course excluding pre-heating/climating, vampire drain and so...).@ResHacker , was the 85 less efficient than this? In similar temps and without box on the roof I am above 300Wh/km even on longer drives and without battery heater (leaving from heated garage, preconditioned). Wondering if it’s a sign that the pack is getting older…
300Wh/km under your conditions seems quite high to me, what is your long average? I think in reality the RWD isn't much less efficient then AWD according to some tests...
