Instead of stepped gears like a conventional transmission, it has a fixed planetary gear, and changes engine speed by adjusting the generator electric load.

FORBES: 2013 Ford Fusion Energi Test Drive And Review: Plug It In And Go

Gearboxes have traditionally been used to speed up the RPM from the rotor to the generator, but they are the weak link in the chain as you get larger.

FORBES: Offshore Wind: Enormous Potential, Huge Challenges

By applying the brakes or reducing speed by letting off the accelerator, the electric motor acts as an electric generator, converting energy that would otherwise be wasted into battery energy.
