4 x 4 Australia - - Gear -

A CON­VEN­TIONAL diff gear­ing sys­tem is lo­cated in the cen­tre, but on ei­ther side of the car­rier is a clutch pack that (when elec­tron­i­cally en­gaged) is able to me­chan­i­cally link the axle di­rectly to the car­rier. Us­ing elec­tronic ma­nip­u­la­tion of the clutch packs, the de­sign­ers are able to vary the torque to each wheel. When turn­ing around a bend, the com­puter is able to pro­vide more torque to the out­side wheels, there­fore im­prov­ing turn-in and han­dling char­ac­ter­is­tics.

If used as the cen­tre diff in a full-time 4WD ap­pli­ca­tion, you could have a ve­hi­cle with a bias to­ward the rear wheels for ev­ery­day driv­ing, but could split the torque 50:50 when off road. This dif­fers from a Torsen diff, where the torque split is me­chan­i­cally set and can’t be al­tered on the fly.
