Self Study Program 383 – Audi TT Coupe 2007 – Body

VAG SSP 383. Audi-Space-Frame ASF of the Audi TT Coupé. The development targets for the bodyshell of the Audi TT With a weight advantage of 48 % over a comparable all-steel bodyshell, in addition to an optimised weight distribution, the new  composite aluminium-steel spaceframe body of the Audi TT marks yet another milestone in the development of modern Audi bodyshells.

Crash safety of the bodyshell is enhanced by means of load-bearing structures at the front end, sides and rear end, with a heavy emphasis on pedestrian safety.

To ensure efficient volume bodyshell production, various new joining and production techniques are employed.

The repair concept is based heavily on the well-known aluminium repair concept. However, of course, the materials combination of aluminium and steel necessitated that new approaches be taken.
