BMW EFFICIENT LIGHTWEIGHT VEHICLE CONCEPT.
When innovation is your guiding principle, unprecedented creativity is inevitable. The
BMW EfficientLightweight concept applied to the BMW i was conceived from the very
beginning to meet the demands of a hybrid sports car. Its innovative LifeDrive architecture
comprises two parts, each precisely tailored to fit their respective requirements. The
aluminium body – or Drive module – contains the lithium-ion high-voltage battery and all
the other drivetrain components front and rear. In between these is the passenger cell, or
Life module. This is built in high-strength carbon (CFRP), a material with ideal properties
for the innovative vehicles from BMW i: extreme stability, ultra-light weight and a degree of
flexibility that allows an unprecedented degree of design freedom. The result is a vehicle
that delivers unique driving pleasure coupled with exceptional economy.
