Sporty driving: The Audi Sport GmbH models are developed and produced for operation on public roads. There are significantly higher stresses when the vehicle is used on racetracks or other closed-off courses (e.g. driving training, driver training courses, and track days). The engine, transmission, clutch, and drive train as well as the chassis, brake system, and tyres are particularly stressed. This can lead to greater wear. Information on the special features when using the vehicle on circular routes or other restricted courses can be obtained from the vehicle literature or your Audi partner.
