An all-wheel drive system for a vehicle having a longitudinal axis includes an electric motor. The electric motor has an output shaft that extends along a first axis, and the first axis is substantially perpendicular to the longitudinal axis. The all-wheel drive system includes a first drive system including a first clutch and a first differential system configured to be coupled to a second drive system and to transfer torque to first wheels of the vehicle in a first state of the first clutch. The second drive system includes a second drive shaft and a second differential system. The second drive shaft is coupled to the output shaft and configured to transfer the torque to the second differential system. The second differential system is configured to transfer torque to second wheels of the vehicle, and the second differential system extends along a second axis substantially parallel to the first axis.

All-wheel drive system for electric vehicle

Locking differential systems, vehicles and methods are provided. An electric vehicle includes an electric motor including a stator and a rotor, wherein the rotor is configured to rotate about a rotor axis; a rotor shaft connected to the rotor for rotation about the rotor axis; a differential located within the rotor shaft; a first input shaft connected to first side of the differential; a second input shaft connected to second side of the differential; a locking system configured to selectively lock rotation of the first input shaft to rotation of the rotor shaft; a control system configured to determine when to lock rotation of the first input shaft to rotation of the rotor shaft; and an actuation system configured to operate the locking system to lock rotation of the first input shaft to rotation of the rotor shaft.
