Using a very complex system of planetary ring and sun gears, plus three clutches and two electric motors, GM engineers were able to extract additional efficiency and range out of the system; up to "two miles," with the help of the ICE in direct drive mode which includes the traction motor at all times states GM's technical paper .
As the paper describes it, the Volt has four driving modes: single motor EV, two motor EV, single motor extended-range, two motor extended range combined. The single e-motor (EM1) is used to launch the vehicle and operate at it lower speeds. It can develop 111kW of power, giving the car brisk acceleration. For high-speed EV-only travel, the electric generator that is attached to the IC engine, converts into an electric motor (EM2), providing additional torque to propel the vehicle using battery power only.
