The BMW ActiveE is a demonstration electric car based on the BMW 1 Series small family cars. It is the second vehicle after the Mini E to be developed under BMW Group’s Project i. The electric drive system is the latest addition to BMW’s Efficient Dynamics programme. The US Environmental Protection Agency official range is 151 kilometres (94 mi), with an energy consumption of 33 kW·h/100 miles, and the agency rated the ActiveE's combined fuel economy at 2.3L/100 km (102 miles per gallon gasoline equivalent).
The ActiveE has a 125 kW (168 hp) electric synchronous motor integrated into the rear axle to power the rear wheels, the same configuration that will be used in the BMW i3. The motor weighs 91 kg (201 lb) and delivers 249 N·m (184 ft·lbf) of torque. The curb weight of the ActiveE is 1,815 kg (4,001 lb), nearly 360 kg (790 lb) heavier than a BMW 135i, but the ActiveE has a 50:50 weight distribution. The liquid-cooled storage cells are located under the hood, in the transmission tunnel and where the fuel tank would normally reside. The rear-mounted electric motor reduces the trunk space to 200 L (7.1 cu ft) versus 280 L (9.9 cu ft) in the standard BMW 1 Series.
