For avoiding torsional vibrations of the vehicle body, the motor vehicle of the present invention uses a drive assembly as an absorber which is held via three bearings in the vehicle body. The bearings having a characteristic which determines a high natural frequency of the assembly roll mode and is modulated precisely to the vehicle body torsion and has a low vertical bearing stiffness.
