The second generation of the Audi A8, Audi R8, TT Coupé and TT Roadster sports cars document the current state of the ASF technology. The superstructure of the current A8 weighs 218kg while the aluminium body of the R8, whose co-supporting engine frame is made of ultra light magnesium, tips the scales at 210 kg.

The TT Coupé and Roadster bodies weigh 206 kg and 251 kg respectively while the TT “family” also features an additional innovation. To ideally balance the axle loads between the front and back, Audi developed an innovative hybrid construction for its compact sports cars: Most of the body is made of aluminium, but steel is used in the rear.

Depending on the model, the kerb weight of the TT has been reduced by between 20 and 90 kg compared to the previous model which had an all-steel body. At the same time, the static torsional rigidity of the Coupé increased by 50 percent and that of the Roadster by an even more impressive 100 per cent.

The ASF provides the foundation for precise handling and a high level of passive safety. A lighter car has to dissipate less kinetic energy and is also does less damage to others involved in an accident. The lightweight design combines chassis responsiveness and efficiency in typical Audi fashion.
