A drive unit in a motor vehicle is mounted with two elastic motor mounts, of which each in each case couples an engine support, connected rigidly to the drive unit, elastically to a body structure of the motor vehicle, and with a torque support which is arranged above the two motor mounts transversely with respect to the vehicle longitudinal axis and which is coupled at one end to the drive unit and is coupled at another end to the body structure and is configured such that the two ends are connected, damped elastically, to one another. There is also provided a damping support arranged at a lower level than the torque support transversely with respect to the vehicle longitudinal axis and which is coupled at one end to the drive unit and is coupled at another end to the body structure. The damping support is configured such that transverse vibrations of the drive unit are damped.
