BMW will introduce a new electric concept model based on the 1 Series Coupe at the Detroit Auto Show.
The BMW Concept ActiveE will follow the MINI E as the second stage of BMW's electric vehicle development program. BMW has begun development of a trial fleet of cars based on the ActiveE as part of a large-scale field test.
The ActiveE is powered by an electric motor BMW claims can produce 170 hp and a maximum torque of 184 ft-lb. BMW also claims a 0-60 time of approximately 8.5 seconds. The entire drive system is fully integrated into the ActiveE's rear axle, taking up about the same space as a conventional vehicle's differential.
Powering the motor is a litihium-ion battery pack specially developed by BMW and SB LiMotive for the ActiveE. BMW says the battery supports a range of 100 miles in everyday use, with a charge time of 4.5 hours using a North American 32A circuit.
The electric motor can also serve as a generator when the accelerator isn't being pressed. The car's kinetic energy is converted into electric power and stored in the battery pack. BMW estimates this process can increase the ActiveE's range by up to 20%.
We'll have more on the BMW Concept ActiveE when it is officially unveiled at the 2010 Detroit Auto Show.
