An electric motor vehicle drive system including a differential electric motor unit for the vehicle including a stator motor element mounted within a supporting frame and a rotor motor element rotatably mounted within the stator. The stator is connected to a first output shaft while the rotor output shaft is connected to a final output shaft through a one-to-one reverse mechanism which corrects or reverses the direction of the final output shaft. Thus, both shafts rotate in the same direction but at one-half relative armature and field structure r.p.m.'s with true differential action within the motor unit itself. The driving connection between the electric motor unit and the motor vehicle in this embodiment comprises a pulley belt combination connected to the vehicle drive wheels and the two output shafts of the motor unit with radius rods for maintaining the adjustable tension on the belt drive. So connected, there is compensation for unequal traction, turning of the vehicle, unequal wheel sizes, etc., and elimination of the usual rear axle reduction gear and differential assembly.
