Self Study Program 391 – Audi TT Roadster

VAG SSP 391. Unfiltered sportiness, a truly authentic driving experience plus high power reserves – cue the new TT Roadster from Audi. The open-top sports car has taken all the design cues from its tremendously successful predecessor, but instils them with even greater emotion, performance and dynamics.

The engine plant at Györ, Hungary, was inaugurated in October 1994.

The plant is not only central to the international competitiveness of company, it also creates in Hungary a solid strategic base that continues to grow in importance.

Virtually the entire Audi range of engines is now assembled in Györ. Volume production of TT models commenced in April 1998.

By the end of 2005, 265, 241 Audi TT Coupés and TT Roadsters as well as 36,458 Audi A3 and S3 models had rolled off the Györ assembly lines.

The new Audi TT Roadster

With its rigorous geometry and clarity, the design of the first TT Roadster elevated it to the status of a cult classic. In designing the new TT Roadster Audi has preserved this charismatic stylistic idiom and carefully honed it for the new model.

Whereas the tail end and the roof section seem to flow into one another at the rear of the TT Coupé, the convertible top of the TT Roadster forms a clear contrast that gives the overall design a more geometric look. This impression is underscored by the athletic curves of the vehicle’s flanks just as much as by the rising dynamic line above the sill area and the taut, muscular shoulder line.

The TT Roadster has a lightweight fabric convertible top which fits in perfectly with the philosophy of puristic open-top motoring and also offers a number of benefits over a folding steel hard top. It is very light and takes up only a small amount of space when folded down. The roof is manually operated or electro-hydraulically powered.

Like the TT Coupé, the body of the TT Roadster is also built on the principles of Audi Space Frame ASF technology, featuring a pioneering hybrid construction that showcases the brand’s tremendous expertise in lightweight design.
