Abstract: 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.
