A motor vehicle with four driving wheels and driven differential gearing for the drive, where (in the case of rotational-speed differences occurring between the wheels) a control device intervenes to distribute the drive power of an engine to the permanently driven wheels and/or the other driven wheels. This intervention occurs for a particular holding time which is progressively extended if a new intervention by the control becomes necessary after a test disconnection of the respective intervention. In addition, or alternatively, the control device can respond more sensitively and thus more quickly to rotational-speed differences of the wheels which may later occur during, or after, a test disconnection.
