Is the optional Sport Differential from Audi worth having?
The self-locking center differential in the classic quattro drivetrain does an excellent job of distributing the power between the axles. To make driving even more dynamic, Audi introduced an additional component in the dynamic S4 Sedan in late 2008 that actively splits the torque between the wheels of the rear axle – the sport differential.
A drive system that transfers power between wheels to provide optimal distribution, dynamic handling and superior safety. Sport differential distributes torque from the engine between the rear wheels to deliver superior traction and avoid under-steer all together.
