Abstract

A motor vehicle electric drive system includes first and second electric machines, arranged coaxial to each other and respectively having first and second rotors, a differential gear having a differential input shaft and a first and second differential output shafts arranged coaxially to the first rotor. A transmission stage has a transmission input shaft and a transmission output shaft. The transmission output shaft is connected in a rotationally fixed manner with the differential input shaft. A first switching element couples the first rotor in a rotationally fixed manner with the first differential output shaft. A second switching element couples the second rotor in a rotationally fixed manner with the second differential output shaft. A third switching element couples the first rotor in a rotationally fixed manner with the differential input shaft. A fourth switching element couples the second rotor in a rotationally fixed manner with the transmission input shaft.
