Audi took advantage of its TechDay Quality event where the company informed us on the methods it uses to achieve quality standards in series production vehicles, to reveal at least one photo of the 2010 A5 Sportback, that of the five-door coupe's tailgate. Using the process of elimination, we also found a few more photos shot during the event that may be of the A5 Sportback but we aren't entirely sure - they could be depicting the A5 Coupe. In any case, hit the jump to check out the pics and a new promo video or click here for details on the Sportback that is set to go on sale in Europe this fall.
