Sports differential – all-round driving improvement

The sport differential, an option for quattro, is designed to make driving smoother, more agile and more satisfying – and not just when you’re pushing the car to its limits.

Safe, accurate turning

The sports differential enables the quattro system to not only transfer torque between the front and rear axles to counter traction losses, but also between the rear wheels. When cornering, power is redirected to the outside rear wheel, literally pushing the car through the corner.  The driver benefits from feeling more in control and the need to make small steering corrections, so familiar in an ordinary car, become a thing of the past.

Why react when you can predict?

Conventional stability management systems detect errors, then correct them. We think that’s a little late. The sport differential’s technology has such a short reaction time - less than 100 milliseconds – that any instability is sensed and dealt with before it has any effect. Almost like it never happened.

You're still in control

The sport differential has been designed to work in tandem with Audi drive select. This enables you to change the characteristics of the engine, transmission, steering, shock absorbers to suit your mood and the demands of the road.
