Prototype "TT RS V6 Biturbo"

In 2013, during the exhibition “Adrenalin pur!” celebrating the 30th anniversary of its subsidiary quattro GmbH, Audi presented the prototype of an Audi TT V6 biturbo of 380 hp. It is the basis of a 2001 Audi TT equipped with the engine of the Audi RS4 Avant B5.

In 2001, the TT was the only sports car in the Audi catalogue. In order to reinforce its sporting image, quattro GmbH wanted to offer a high-performance version and launched the project. The design of this prototype lasted 8 months.

This is more of an RS4 with a TT body than a TT with an RS4 engine. Indeed, the car uses the chassis, engine, Torsen all-wheel drive, rear differential, axles, brakes and even the wheels of the B5 Avant. The chassis has been shortened by 170 mm to match the wheelbase of the TT.

After the technical tests were completed, including more than 20,000 km of driving, it was decided not to commercialize it. Manufacturing costs would not have been profitable on low production.
