Audi has unveiled a limited edition TT RS with a unique finish, not only to celebrate four decades of quattro but also the heritage it has built from motorsports.

Its Alpine white paint is topped off with decals on the hood, shoulders, roof and rear; paying tribute to the Audi Sport quattro S1 driven by Walter Rohrl to victory at the 1987 Pikes Peak race in the United States. The hood with central air vents in gloss carbon adds another visual highlight while also improving on engine compartment ventilation.

The Audi TT RS also gets an aero kit that consists of a front splitter, side skirts, a fixed rear wing and diffuser which were developed in a wind tunnel. The ensemble is then finished with 20-inch alloys wheels.

On the inside, customers can opt to replace the rear seats with a strut brace made entirely of carbon fibre. It not only improves the TT RS’ torsional rigidity but also sheds 16 kg off its weight.

Otherwise, there’s plenty to remind you that it’s no ordinary TT RS. “40 years of quattro” inscriptions are seen on the seats, wrapped in a mix of Nappa leather and Alcantara, and on the gear knob. The gear knob in particular even displays the serial number of the car. Only 40 units of the TT RS 40 years of quattro will ever be made.

Under the hood is a 2.5-litre 5-cylinder TFSI engine from Audi Sport that has won the “International Engine of the Year Award in nine consecutive years. It makes 400 hp adn 480 Nm to power all four wheels via a 7-speed dual clutch transmission. 0 to 100 km/h is done in just 3.7 seconds, with top speed de-restricted to 280 km/h!
