The gearbox is part of the car's powertrain (power transmission) between engine and drive wheels. The function of the gearbox is to change the gear ratio depending on speed and power requirements.

The car has an eight-speed automatic gearbox, and an electric motor for rear-wheel drive. The number of gear changes means that the engine's torque and power range can be used effectively. Two of the gears are overdrive gears that save fuel when driving at constant engine speed. It is also possible to select gears manually. The driver display shows which gear position is currently in use.
