There are two main types of gearbox, manual and automatic.
The manual gearbox has six gears and the automatic gearbox has eight. The number of gear changes means that the engine's torque and power range can be used effectively. In the automatic gearbox, two of the gears are overdrive gears that save fuel when driving at constant engine speed.
It is also possible to select gears manually with the automatic gearbox. The driver display shows the selected gear position.
