BMW i3 94Ah range under different conditions and battery health levels.
About these figures
- WLTP figure is for the 2017 facelift and varies 146 to 158 miles by wheel and trim; the conservative end is used. Pre-facelift 2016 cars were NEDC-rated only at 195 miles.
Why real range is below the official figure
WLTP tests run in mild lab conditions at gentle speeds, so nearly every EV undershoots the sticker in real driving. For the BMW i3 94Ah, a fair planning figure is about 124 miles, roughly 85% of the official 146. That works out at about 4.6 miles per kWh from the 27.2kWh usable battery.
- Motorway runs at 70mph cost the most: air resistance rises sharply with speed
- Winter takes 20 to 25% off: expect around 95 miles on a cold day with the heating on
- Gentle town driving can beat the realistic figure, sometimes even the WLTP one
How battery health changes the picture
Range fades slowly as the battery ages. At 90% battery health the realistic range drops to about 111 miles, which most owners barely notice day to day. At 70% health, the typical warranty threshold, it falls to about 87 miles.
If you are buying a used BMW i3 94Ah, that spread is the reason to get the battery's actual state of health measured rather than guessing from the odometer. A specialist reads it directly from the car in under an hour.
