1. A drive system for a motor vehicle, comprising:a drive train comprising a transmission; an internal combustion engine having a drive shaft and acting on the drive train; an electric machine which is a combined starter for the internal combustion engine and generator for the motor vehicle, the electric machine having a rotor which is permanently coupled to the drive shaft, so that the drive shaft and the rotor always rotate in unison with the same rotational speed, wherein the electric machine is an internal rotor machine; and a single clutch, which is arranged in the drive train between the rotor of the electric machine and the transmission, wherein the clutch is a frictional clutch having at least two frictional connection elements rotating with the rotor and at least two frictional connection elements rotating with the transmission, wherein the frictional connection elements are immersed in a clutch fluid, and wherein the clutch is mounted in the rotor of the electric machine.
