Audi has unveiled the revised Sport Quattro concept ahead of the car's public debut programmed for next week at Frankfurt Motor Show.

The Audi Sport Quattro was introduced in 1984 and was brought back to life towards the end of 2010 by a concept which was rumored to enter production but never did. Now, the Ingolstadt-based automaker has revised the concept and will show it in several days at the Frankfurt Motor Show.

Dressed in bright yellow, the 2013 Sport Quattro is an evolution of the previous concept and carries a similar large hexagonal front grille and redesigned taillights united by thin red bar. Audi kept the air outlet on the right side of the bonnet and decided to redesign the alloy wheels as well as increase the size of the two exhaust pipes.

The power door handles are now painted in the same color as the body, while the front bumper has gained considerably larger air vents. We also notice the aggressive LED headlights, 21-inch alloy wheels shod in 285/30 R21 tires, a rear spoiler and carbon fiber ceramic brake discs. The fenders and doors are made from aluminum, along with carbon fiber reinforced polymer (CFRP) roof, engine hood and rear hatch. The 1,850 kg (4,078 lbs) concept is 4602mm (181.18 inches) long, 1964mm (77.32 inches) wide and 1386mm (54.57 inches) tall, with a 2784mm (109.61 inches) wheelbase and a trunk capacity of 300 liters (10.59 cubic ft).

Open the doors and discover an uncluttered, driver-focused cabin with very few buttons and knobs. There are digital instrument clusters, including the centrally-mounted rev counter flanked by the Le Mans map on the left and lap times on the right. Several other virtual 3D displays are available and can be selected from the multi-function sport steering wheel.

At its heart is a 4.0-liter twin-turbo V8 TFSI engine generating 560 HP (412 kW) and 700 Nm (516 lb-ft) of torque. The conventional power unit works together with an electric motor that has been installed between the V8 mill and the reworked eight-speed tiptronic gearbox. The 150 HP (110 kW) and 400 Nm (295 lb-ft) electric motor takes its energy from a liquid-cooled lithium-ion battery mounted at the back which has a capacity of 14.1 kWh.

Thanks to this hardware arrangement, the 2013 Audi Sport Quattro Concept has a combined output of 700 HP (515 kW) and 800 Nm (590 lb-ft), good enough for a 0-62 mph (0-100 km/h) run in only 3.7 seconds and a top speed of 189.52 mph (305 km/h). It can travel on electric power for up to 31 miles (50 km) and has an average fuel consumption of 2.5 liters / 100 km (94 mpg US or 113 mpg UK) with CO2 emissions of 59 g/km. These impressive figures are also possible thanks to the engine's cylinder on demand (COD) and start-stop systems.
