The Audi Sport quattro concept was unveiled at the 2013 Frankfurt Motor Show to commemorate the 30th anniversary of the original Audi Sport quattro. The show car features angular flat C-pillars, as well as the rectangular double headlights featuring Audi’s Matrix LED technology, a spoiler at the lower edge of the rear window, rectangular tail lights, 21-inch wheels, carbon fiber-ceramic brake discs, bucket seats with integrated head restraints, multifunction sport steering wheel, two driving modes (race and setup) in virtual 3D displays, Audi MMI control unit, and air conditioning. The doors and fenders are aluminum, while the roof, hood, and the rear hatch are made of carbon fiber-reinforced polymer. The front suspension features five control arms per wheel while the rear has track-controlled trapezoidal link.
Power is from a 4.0 TFSI V8 engine rated at 560 PS (412 kW; 552 hp) and 700 N·m (516 lb·ft), along with a disc-shaped electric motor rated at 150 PS (110 kW; 148 hp) and 400 N·m (295 lb·ft) (for combined power 700 PS (515 kW; 690 hp) and 800 N·m (590 lb·ft)), mated to an eight-speed tiptronic transmission. A liquid-cooled 14.1 kWh lithium-ion battery is in the rear, and the show car’s range is claimed up to 50 km (31 mi) on electric power alone.
At the 2014 Geneva Motor Show, Audi presented the new 2014 Audi TT Quattro Sport Concept. It is powered by a 2.0 L four-cylinder TFSI engine that can produce 420 PS (309 kW; 414 hp) and 331 N·m (244 lb·ft) of torque. It uses Audi’s Quattro AWD system and an S Tronic dual-clutch transmission.
