Modes of Operation

WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.

Electric

The system operates in this mode when the vehicle is propelled by the electrical power stored in the high voltage battery. The torque is supplied to the output shafts by the electric 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.

Drive - The electric motor drives transmission providing torque to wheels meeting driver demand.
Driven -The transmission is driven by inertia of vehicle and provides regenerative energy to electric motor meeting all or a portion of the braking demand.

Hybrid

The system operates in this mode when the engine is running and powering the electric motor which produces the electricity. The electricity produced by the electric motor charges the high voltage battery. In this mode the electric motor can operate as a motor or as a generator to make up the difference between engine torque and desired torque at the wheels. This mode is preferred whenever the electric battery needs to be charged or at moderate loads at low speeds.

Drive - The engine drives the transmission providing torque to the wheels meeting driver demand. Requested torque above this demand is used to charge high voltage battery through the electric motor. Electric motor can also assist engine.
Driven - The transmission is driven by inertia of vehicle and provides regenerative energy to electric motor meeting all or a portion of the braking demand. Engine can provide compression braking.
