Electric Mode

The system operates in this mode when the vehicle is propelled by the electrical power stored in the high voltage traction battery. The torque is supplied to the output shafts by the traction motor. This is the preferred mode whenever the desired torque is low and can be produced more efficiently by the electrical system than the engine. The electric mode is also used in reverse because the engine can deliver torque only in a forward direction.
