Does 21 M3 SR+ come with 82 kw battery or is it just for LR and Performance? Thank you in advance!

Thanks!No, there isnt any reason to put a pack that size into the SR/SR+ so no.
Weight means basically nothing at highway speeds. The advantage is during acceleration and braking.It's actually an advantage for the SR+. Fewer physical cells means the SR+ is much lighter; I regularly achieve around 200 wh/mi at reasonable highway speeds.

~ 8 - 9 Newtons per 100 Kg, so 2.2 - 2.5 Wh per Km.
At EPA type speeds, ~ a 1.0 - 1.5% difference in fuel economy per 100 Kg
I would expect the acceleration/deceleration weight penalty to show up in the city MPGe but not the highway MPGe.So a difference in curb weight of about 200 kg would account for 2% increased fuel economy. Looks like the SR+ is about 14% more efficient than the LR AWD according to the EPA. Is the rest due to the lack of a second motor, and the efficiency gained during acceleration/deceleration?
