Audi TT clubsport turbo

The designers of the Audi TT clubsport turbo engineering prototype, which was unveiled on 13 May 2015 in Reifnitz am Wörthersee, were inspired by the legendary Audi 90 IMSA GTO from 1989. But the engineers were in new engineering territory. The more powerful 2.5 TFSI engine is even more dynamic thanks to an electric biturbo. In the lower speed range, the torque is thus increased by up to 200 Nm.

But it is not just the power of the five-cylinder engine that is enthralling; its unmistakeable, throaty sound is also thrilling. The exhaust system is designed for a minimum backpressure, with a sidepipe discharging straight after the racing silencer. The 2.5 TFSI is cooled by a water cooler from the world of motorsport. Power is provided by the car’s own 48-volt onboard power supply, another important technology for the future from Audi. The power of the Audi TT clubsport turbo is delivered to the road effortlessly via the quattro permanent all-wheel drive, whose multi-disc clutch is seated on the rear axle for better weight distribution. A coilover suspension makes it possible to adjust the trim height of the body and the rebound and compression stage of the dampers with high precision. The tyres fitted on the wheels with a 9.5 J x 20 format are from the standard range, unlike the carbon-fibre ceramic brake discs which are particularly light and resistant to abrasion. Track widths of 1,736 mm at the front and 1,729 mm at the rear give the compact sports car a powerful presence on the road.

When the side mirrors are included, the car is 1.97 metres wide – 14 centimetres wider than its engineering prototype. The angular wings form add-ons in their own right and are open at the front and rear, so the air flows through them and cools the brakes. The single-frame grille and the large air intakes, which continue the light signature of the matrix LED headlights with their vertical bars, are also optimised for maximum air flow.

The manually adjustable rear spoiler is an evolution from the Audi Sport TT Cup, but 20 centimetres wider. The wing is also made from carbon-fibre-reinforced plastic (CFRP), as are the air intakes and the large splitter at the front, the wings and side skirt trims as well as the bulky diffuser at the rear.

The show car, which was originally painted in ferrotitanium, was reconfigured in motor­sport colours to mark the 40th anniversary of the legendary record-breaking Pikes Peak climb and presented in Colorado together with the original Audi Sport quattro S1.
