A differential assembly including a rotatable casing having an axis of rotation, a selectively energized electromagnet proximal the casing, and a rotatable first clutch disposed within the casing, the first clutch placed in operativ e engagement with the casing in response to the electromagnet being energized. Relative rotation between the first clutch and the casing is slowed by their being in operativ e engagement. A rotatable clutch hub and a second clutch are disposed within t he casing, and the casing and the clutch hub are rotatably coupled through engagement of the second clutch, which is operatively engaged in response to relative rotation between the first clutch and the casing being slowed. At least one rotatable pinion gear is disposed within the casing and revolves about the axis of rotation. At least one side gear engaged with the pinion gear and rotatable about the axis of rotation is disposed within the casing, and is rotatably coupled to the casing through t he second clutch during engagement of the second clutch. Neither of the first clutch a nd the second clutch is appreciably engaged with the casing in response to gear separating forces exerted between the pinion gear and the side gear.
