Dr Ulrich Hackenberg, Audi's chief technical officer, said, "With our quattro sport concept we wanted to demonstrate what the new TT’s technology can do if you take it a step further.
"We shall use it to achieve a new position for the TT, and also for racing," said Hackenberg. "The car will be a track-focused quattro GmbH product, but it will not be RS-badged. It's designed as an affordable Club Sport version of the TT rather than something like a GT3 car."
Audi's concept, which is based on the recently revealed TT, packs a 2.0-litre turbocharged engine that produces 414bhp and 332lb ft of torque.
That means the engine – which features a forged crankshaft, a newly developed turbocharger and a gas-flowed cylinder head – produces 207bhp per litre, eclipsing the likes of the Mercedes A45 AMG's 178bhp per litre.
"When I arrived at Audi I asked the engineers for more power from the 2-litre TFSI engine," said Hackenberg. "They offered 400bhp. I told them to keep going, so now we have 414bhp thanks to 1.8bar of boost."
Power is sent to all four wheels via a six-speed dual-clutch transmission and Audi's quattro system, with the resulting traction allowing the concept – which weighs 1419kg with a driver – to make best use of its power.
Audi has worked to improve the TT's dynamic capabilities too, with lower and stiffer suspension. Other upgrades include 20-inch alloys with centre-lock fitment, semi-slick tyres, a carbonfibre spoiler to boost downforce and a 'single-frame' Audi grille.
Inside, the interior resembles that of the series-production TT but features Alcantara trim, low-slung bucket seats, four-point harnesses and storage for two racing helmets.
The new Audi TT quattro sport concept isn't mooted as a replacement for the RS variant, but Audi has clearly suggested that it is now looking to do more with the RS's five-cylinder engine as a result of the quattro sport's output.
Hackenberg concluded, "The quattro sport is a car for the motorsports enthusiasts among our customers."
