Abstract
The invention relates to a motor vehicle that is provided with a device for testing the systems, functions or components of the vehicle. According to the invention, the vehicle is jacked-up and is equipped with an actuator or a driver to operate the brakes of the vehicle. The vehicle propulsion can rotate freely against the load of at least one brake of the vehicle and the freely rotating wheel or wheels have no frictional connection to the tread contact area of the vehicle. The brakes and/or the propulsion load can be controlled by actuators having a controller or by the driver in accordance with specific signals of the operating condition of the drive train of the vehicle.
