Wow, who would have guessed that Audi would take its A3 hatchback and turn it into a sedan? This car is described by Audi as a "concept technical study," but it could also be called a winner. The front end treatment is reminiscent of the handsome Quattro Concept, the engine is a 2.5-liter five-pot turbo (ah, the heritage) making 403 hp and 368 lb-ft, the transmission is a seven-speed dual-clutch affair and this concept has all-wheel drive. The real A3 is due in the States in 2013 as a 2014 model. If it looks anything like this, there should be plenty of interested parties.
