In a motor vehicle having driveable wheels (3-6) both front and rear, the wheels on which drive is required or possible are automatically selected in each driving situation whilst underway. The necessary engine torque is automatically distributed between drien wheels with regard to the road adhesion prevailing on those wheels. For this purpose, the vehicle contains a control unit (18), which by way of various sensors (19, 20, 22-25) on the vehicle obtains information on the current driving situation, and which is designed to determine on which wheels drive is required or possible. The control unit then distributes the necessary engine torque between the drivent wheels in each driving situation.
