The Automotive Differential transmits power from the engine to the driving wheels while allowing them to rotate at different speeds when the driving conditions call for it, such as during a turn. To make things more interesting, this model uses a hypoid pinion/ring gear pair instead of a bevel gear pair. The model is powered by a 6V electric motor equipped with a speed reducer.
