BMW ActiveE project i Megacity Concept Revealed

Mike Stevens | Dec 17, 2009

TO BE UNVEILED at next month's Detroit Auto Show, BMW has today revealed its upcoming all-electric Concept ActiveE. The new concept forms part BMW's project i Megacity Vehicle project.

Based on the 1 Series Coupe, the ActiveE follows the MINI E as BMW's second large-scale electric test program to be conducted in cooperation with interested customers.

As with the MINI E, the ActiveE will be used as everyday vehicles by select private and fleet customers in Europe and the US, the results used to further develop BMW's upcoming electric vehicle range.

As reported previously, BMW will launch an all-electric sub-brand in the first half of the next decade.

The ActiveE features a new synchronous electric motor located in the rear axle, producing 125kW and 250Nm of torque, propelling the Coupe to 100km/h in 9 seconds and a maximum speed of 145km/h.

Unlike asynchronous electric motors, the ActiveE's motor provides a relatively high level of torque even at higher engine speeds and road speeds.

Thanks to the more powerful lithium-ion system (compared to the nickel metal hydride technology used in most hybrid vehicles), the ActiveE achieves a driving range of 160km from one charge.

Up to 20 percent of the electric car's driving range is gained when the driver's foot is removed from the accelerator pedal, the ActiveE's kinetic energy recovery systems kicking in to charge the electric motor.

The energy recovery process creates a brake torque, allowing simple deceleration manoeuvres. Regular deliberate braking engages the conventional hydraulic braking system, and Dynamic Stability Control is featured.

On the European power grid, the battery pack can be fully charged in just 3 hours via a 240 volt outlet.

More details are expected to be revealed at the ActiveE's Detroit Auto Show unveiling next month.
