quattro® with sport differential > Glossary > advice > Audi Worldwide
Does anyone know if Audi's version of torque vectoring, called sports differential, will become available on the A3/S3. Or are they keeping it for their higher end models? I don't see it as an option on the S3 configurator. It is on the more powerful A4/A5 and the S4/S5 - under Equipment > Safety & Technology > Suspension Inovation - only a £620 option.
For anyone who has not heard of this: a torque vectoring differential will allow vairing amounts of power to be delivered to the rear wheels. This is supposed to reduce understeer even further in 4WD cars. Basically, in a corner the outside rear wheel will get more power and in effect help steer the car round a corner.
