A performance-focused show car based on the all-new TT has been unveiled by Audi at the current Geneva Motor Show.
The four-cylinder, 2.0-litre TFSI engine in the TT quattro sport concept delivers 414 bhp at 6,700 rpm. Its specific output is 207 bhp per litre of displacement – more than 2001’s victorious Le Mans R18 racing car, which combined turbocharging with FSI direct injection for the first time in an Audi petrol engine. It also makes a maximum of 450 Nm of torque (331.90 lb-ft) available from 2,400 to 6,300 rpm, and even at 1,900rpm is able to deliver over 300Nm (221.27 lb-ft).
Tipping the scales at 1,344 kilograms, helped by paring back interior trim and equipment, and by the production car’s Audi Space Frame construction and aluminium panel content, the TT quattro sport concept achieves a power-to-weight ratio of 308 bhp per ton. As a result, the four-cylinder engine enables the car to go from 0 to 62 mph in a claimed 3.7 seconds.
“With our Audi TT quattro sport concept show car, we wanted to demonstrate what the new TT’s technology can do if you take it a step further,” said Audi boss Ulrich Hackenberg. “This car is designed for racing – an extreme driving machine for the motorsports enthusiasts among our customers.”
The flat Matrix LED headlights, enlarged air intakes and broad “Singleframe” grille with its quattro logo and dark diamond patterned centre section dominate the study’s front view. A splitter made of carbon-fibre-reinforced polymer (CFRP) rounds off the front end at the bottom and increases the downforce on the front axle.
The regular TT wheel arches, which frame 20-inch wheels and semi-slick tyres, are extended by a further 30mm, and are connected by sill extensions. Their lower segments are also made of CFRP.
At the rear, the wide CFRP diffuser is delineated by vertical edges and it surrounds two large, fully circular tailpipes. Large air outlets are positioned on the sides beneath the taillights, while a large, fixed wing increases the downforce on the rear.
Underneath, a modified chassis – MacPherson suspension with aluminium components at the front and a four-link layout at the rear – gives the concept sharper handling, helped by a 54 per cent to 46 per cent weight distribution and a stiff set-up which brings the body closer to the road than the series-production TT.
