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.
