BMW Concept ActiveE – electrically-powered BMW image

The BMW Concept ActiveE provides a taste of a purely electrically-powered BMW. Focused on the requirements of practical use, the study is based on the BMW 1 Series Coupe and embodies the characteristic driving of the 1 Series for the first time as part of an emissions-free drive concept.

The BMW Concept ActiveE is the BMW Group’s second vehicle after the MINI E to be developed as part of project i.

The BMW Concept ActiveE is powered by a new synchronous electric motor specially developed for this vehicle. Its maximum output is 170hp, the maximum torque of 250Nm is available from standing as is typical for electric motors and remains available over an unusually broad load range. For the first time, electrical energy is stored in a lithium-ion battery pack developed jointly by BMW and the co-operation partner SB LiMotive especially for the BMW Concept ActiveE. A new stable temperature regulation function optimises the battery pack’s performance.

The electric motor is completely integrated in the rear axle, the power electronics is positioned above the motor. Space is used for energy storage which in vehicles powered by a combustion engine would be taken up by the conventional drivetrain and fuel tank. With a weight of some 1,800 kilograms (unladen weight according to DIN), a low center of gravity and an axle load distribution which is typical of a BMW, the vehicle has everything it requires to provide the dynamic driving properties and agile handling in the style of the BMW 1 Series.

Predicted driving performance figures: acceleration from zero to 37mph in less than 4.5 seconds and from zero to 62mph in less than 9 seconds, maximum speed: approx. 90 mph, (electronically-limited).

On the European grid, the battery pack can be fully charged at a high-current power outlet (50 ampere) in as little as three hours. In North America, using a high-current (32 ampere continuous) residential wall box, the charge time is about 4.5 hours.
