THE BMW ActiveE

Based on the current BMW 1 Series Coupé, the BMW ActiveE is the second electric test vehicle to be created by the BMW Group.

At the heart of the BMW ActiveE is a powerful electric synchronous motor which propels the car from zero to 60mph in just nine seconds, delivering 168hp and maximum torque of 250Nm, from a standing start. While its top speed is electronically limited to 90mph. The BMW ActiveE maintains the dynamic driving style that is typical of a BMW, with a low centre of gravity and 50:50 weight distribution to enhance traction and power transfer of the high torque.

Replacing the engine block, transmission and fuel tank are three large energy storage units containing lithium-ion cells, developed in conjunction with SB LiMotive. These modules are protected by a steel-plate battery housing with integrated liquid cooling system, to keep the batteries at optimum operating temperature helping to increase the range. These housings also help to ensure that the BMW ActiveE meets the same stringent safety standards as the BMW 1 Series Coupé, meeting and exceeding the levels legislated.

The BMW ActiveE is engineered so that when the driver takes his foot off the accelerator pedal the motor becomes a generator and feeds the electricity created from kinetic energy back into the vehicle battery, while at the same time braking torque is created, slowing the vehicle down. This recuperation of energy can increase the range by up to 20 per cent.
