I haven't noticed that driving mode makes any difference in regen power in our 2014 BEV, so my observation agrees with yours.

2017 BMW i3/Curb weight - 2,799 to 3,234 lbs

2014 BMW i3/Curb weight - 2,799 to 3,064 lbs

Potentially BMW reduced it for some reason. :roll:


Yes, they likely reduced, and not bothered to provide the stetting in the menu. Hopefully coding should fix this issue

I have a 2014 BEV (April 2014 production) and couldn't believe BMW's curb weight claims were real.

In frustration, I took my i3 to a local truck scale. With zero persons in the car – and perhaps 40 lbs. (max) of detritus in the car, I got an empty weight of 2,880 lbs. (1306 kg).

I should do the same with our August, 2014, BEV.

The listed curb weight is likely for the lightest version with no options (i.e., the lightest 19" pizza slice wheels, 5" rear wheels with 155 mm tires, no DCFC, only 3.7 kW AC charging, no heat pump, no burglar alarm, base entertainment system, no Comfort Access, base cloth interior, no rear camera, no front ultrasound parking sensors, etc.). All U.S. BEV's were delivered with 7.4 kW AC charging (i.e., with a KLE module that's missing in the 3.7 kW AC charging version), a heat pump, and a burglar alarm, so no U.S. BEV is likely as light as 2,634 lb.

My regenerative braking is breaking every time I shift into "N".
