BMW 3 sērija 1983: Viscous coupling locking central differential with 37% front / 63% rear torque split. The viscous coupling is integrated into the planetary central differential. It locks the differential in the event of wheel slip and transfers up to 90% of the torque to the axle with traction. The viscous locking rear differential distributes torque between the rear wheels. Audi A4 1995: The vehicle features full-time Quattro IV all-wheel drive with Torsen center differential and electronic traction control that operates at speeds up to 40 km/h and applies brakes to spinning wheels, with the effect of locking the front and rear differential. | |||
