Audi Sportback Concept previews the future A7 |

At the Detroit Motor Show, which is happening as we speak, the Audi Sportback Concept was unveiled. Though the German carmaker didn’t confirm, the concept most likely previews the future Audi A7 four-doors coupe. A proof that the project is quite advanced is the technology behind the Sportback concept. Under the hood there’s a 3.0 liter V6 TDI clean diesel which delivers 165 kW (225 hp) and 550 Nm (405.66 lb-ft) of torque and with only 156 g/km (251.06 g/mile) of CO2 emissions, it meets the emission standards of all 50 U.S. states and the Euro 6 standard scheduled to take effect in 2014.

Featuring a new 7-speed tiptronic gearbox and quattro permanent all-wheel-drive system, the Audi Sportback Concept is able to sprint from 0 to 100 km/h (62 mph) in under 7 seconds and up to a top speed of 245 km/h (152 mph), while managing to achieve a fuel consumption of 5.9 l/100 km (39.87 US mpg), which is, we must say, incredible.

The car looks pretty good, with several styling influences from other VW Group cars (the headlights are similar to those from the Audi R8, while the rear part reminds us of the awesome Lamborghini Estoque, even though Audi mentions that it’s inspired by the A5).

Update: We’ve also added a short video of the concept, released by Audi.
