The new Audi TT quattro sport concept, an "extreme driving machine" capable of 0-100kph in 3.7sec according to its maker, has been unveiled at the Geneva motor show.
Audi's concept, which is based on the recently revealed TT, packs a 2.0-litre turbocharged engine that produces 414bhp and 46kgm 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.
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.
Dr Ulrich Hackenberg, Audi's chief technical officer, said, "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."
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.
Hackenberg added, "It's a car for the motorsports enthusiasts among our customers."
