The new G-Class is not only powerful, it is also smart. That's why it only ever uses its power where it is needed: cross-country it might occur that only one wheel has traction. In this case, three mechanical locks, on the central differential as well as the rear axle and front axle differential, ensure that the traction of a wheel allows the progress of the G-Class.
The availability of equipment depends on the engine and the configuration selected. You will find details in the equipment information for each model.
