It also, though, has an electric motor that provides additional power to the rear wheels (through the same gearbox) and a second electric motor connected directly to the front axle.

ECONOMIST: Fast cars will go even faster with electric power

In addition to the petrol engine and electric motor, the LF-CC hybrid drive system further comprises a generator, a high-performance battery, a power split device which, via planetary reduction gears, combines and re-allocates power from the engine, electric motor and generator according to operational requirements, and a compact power control unit to govern the high speed interaction of the system components.
