THE STORY OF BMW i

LIFEDRIVE ARCHITECTURE


BMW LifeDrive is an architectural concept that was purpose-built for electric vehicles. Comprised of two separate units, the Life Module and the Drive Module form the framework of all BMW i vehicles.

The Life Module is a high-strength and lightweight passenger compartment made from Carbon Fiber Reinforced Plastic (CFRP), which could be thought of as the passenger cabin.

The Drive Module, which is constructed out of aluminum, consists of the 22-kWh, lithium-ion battery, electric drive train, MacPherson strut, 5-link rear suspension, and structural components. The lithium-ion battery cells are stored beneath the passenger compartment of the car, giving the vehicle an optimum 50:50 weight distribution and low center of gravity.

Another benefit of BMW i's LifeDrive architecture is the lack of a space-consuming transmission tunnel running through the center of the car–because of the separate Drive Module. This gives the BMW i3 the interior space of a BMW 3 Series, while having the footprint of a much smaller BMW 1 Series.
