1. A vehicular drive unit for a battery electric vehicle (BEV), comprising:
an electric motor, for propelling the BEV, having an output shaft;
a first planetary gearset, having an input and an output, coaxial with the output shaft of the electric motor;
a sprocket coupled to the output of the first planetary gearset;
a second planetary gearset, having an input and an output, coaxial with a driveshaft of the BEV; and
an endless loop rotatably coupled with the sprocket, and the input of the second planetary gearset, such that the output of the second planetary gearbox is coupled to the driveshaft of the BEV thereby configured to transmit rotational movement of the output shaft of the electric motor to the drive shaft of the BEV, wherein an axis of rotation of the drive shaft of the BEV is offset from an axis of rotation of the output shaft of the electric motor and wherein the vehicular drive unit consists of a single electric motor driving one or more wheels of the vehicle.
