The premium unit of German brand Volkswagen, Audi is famous for its unmatched interiors and not just us, but even GM seems conscious of this fact. GM’s Vice President of Global Engineering, Karl Stracke is the one who has gone public with his viewpoints regarding the Audi interiors quality. As per Karl, GM is fast-improving the quality of its interiors but it is still to meet the benchmark set by Audi. Karl mentioned that he recently drove the Corvette Grand Sport and he did like the performance but what did not convince him were the interiors. GM is putting in serious efforts to improve the quality of interiors and the company has recently started a program that lets the company engineers test competitor’s products every Friday at the Milford Proving Grounds.

Pretty lightweight but packed with goodies, the new Audi A8 is in direct competitor to the BMW 7 Series, with Mercedes-Benz S-Class, Lexus LS and Jaguar XJ considered as secondary rivals. The new technology advances installed in the car include the new-generation MMI system, the latest quattro AWD system and the regenerative brakes. As for what sends power to the wheels, a wide range of engine is available, out of the which a 184kW (250hp), 550Nm 3.0 TDI engine or the 4.2 petrol V8 that churns 274kW (373hp) and 445Nm of torque.

Looks damn cool, don’t you think?

Slated for an early debut next year at the Detroit Auto Show, the 2011 Audi A8 is one of the most thought-after luxury sedans. Caught testing on the Nurburgring circuit, rumors have it that the upcoming model comes with new engines. Apparently there’s the new 6.5L V12 which replaces the 6.1L variant for a monsterish output of over 500 horsies, or the supercharged V8 capable of churning 400 hp. Mileage is also on the priority list for Audi which means the new A8 lineage will also include a 2.0L diesel option mated with twin turbos that sport some 200hp. For those who can afford it, sales will begin late 2010. [via Autoblog]
