ABSTRACT:
An all-terrain or utility vehicle having various combinations of left and right front wheels, left and right rear wheels, a differential rotationally variably coupling the left and right front wheels together with a variable coupling torque and a source of motive power being selectively coupled to the left and right rear wheels in one configuration and coupled to the left and right front wheels as well as to the left and right rear wheels in a second configuration. The coupling torque is relatively stronger when a speed of the vehicle is relatively slower and is relatively weaker when the speed of the vehicle is relatively faster. The second configuration is selectable from the first configuration while the vehicle is in motion and (1) a rotational difference in speed exists between at least one of the left and right front wheels and at least one of the left and right rear wheels and (2) a rotational speed of at least one of the left and right rear wheels exceeds a rotational speed of at least one of the left and right front wheels.
