The invention relates to a motor vehiclewith a drive engine and transmission connected downstream in the power flow, whereinthe transmission comprises a transmission output shaft on the output side, via which drive power of the drive engine is transferred indirectly onto the drive wheels of the motor vehicle;with a universal shaft which is connected directly or indirectly to the transmission output shaft in order to transfer drive power from the transmission output shaft via an axle gear or the like onto the drive wheels;with a vehicle frame, on which the drive engine, the transmission, the universal shaft and the drive wheels are suspended or mounted at least indirectly;with a hydrodynamic retarder, electromagnetic retarder or permanent magnet retarder, comprising a rotor and a stator, which are switchable via a hydrodynamic working medium circuit or a magnetic field into a torque-transferring connection, so that the rotor is braked by torque transfer to the stator, with the rotor being in a drive connection with the drive wheels in order to brake same, wherein the rotor is mounted on the universal shaft on the outside and is supported by the same. The motor vehicle according to the invention is characterized in that the stator is relatively supported by means of a retarder bearing, and is supported by the rotor and is supported against rotating by means of a torque support at least indirectly on the vehicle frame.
