Audi has revealed at the 2014 Geneva Motor Show the all-new 2014 Quattro Sport Concept. Under the hood of the German prototype is an updated four cylinder 2.0 liter TFSI engine rated at 420 horsepower and 450 Nm peak of torque. 

According to Audi, the engine weights only 150 kilograms and is able to offer 210 horsepower per liter of displacement. 

The Audi quattro sport concept tips the scales at 1,344 kg (2,963 lbs) and sprints to 62 mph (100 km/h) in only 3.7 seconds thanks to a quick S tronic dual-clutch gearbox sending output to the quattro all-wheel drive system.

The flat Matrix LED headlights and the broad Singleframe grill dominate the study’s front end. The grill’s striking frame displays the quattro logo and holds the dark diamond-pattern grill.
Through their pronounced edges, the substantial air intakes – which also feature diamond-pattern grills – appear almost like inserted airboxes.
 
They thus illustrate a key element in the new Audi TT’s design language: elements like the greenhouse and wheel arches create the impression of being individual bodies, thus producing the typical tension. The show car rests on 20-inch wheels with a central locking mechanism and semi-slick tires.

The show car interior has been reduced to the essentials, doing away with numerous components that are dispensable on the race circuit.
 
The door panels have been stripped of armrests and speakers – the interior is characterized by Alcantara. A dominant diagonal strip of Alcantara acts as a door pull handle, the door openers feature a filigree design. Low-set racing buckets serve as seats, featuring black four-point seat belts with white accentuating stripes. The luggage compartment offers space for two racing helmets.
