A differential device for transferring torque and rotation from an input shaft to a first output shaft and a second output shaft of a vehicle is provided. The differential device includes a carrier coupled to an input shaft, a first pump/motor coupled to the carrier and to the first output shaft, and a second pump/motor coupled to the carrier and to the second output shaft. The first pump/motor preferably functions to pump a hydraulic fluid upon a rotation of the first output shaft at a different speed than the carrier, and to rotate the first output shaft at a different speed than the carrier upon a sufficient pressurization of the hydraulic fluid. Similarly, the second pump/motor preferably functions to pump a hydraulic fluid upon a rotation of the second output shaft at a different speed than the carrier, and to rotate the second output shaft at a different speed than the carrier upon a sufficient pressurization of the hydraulic fluid.
