There goes Audi's surprise premiere; the first official photos of the firm's Detroit Show Sportback concept have been leaked into the internet. The first thing that caught our attention on Audi's concept study is without doubt the Sportback's rear-end and the similarities it shares with the Lamborghini Estoque saloon that was unveiled at last year's Paris Show. There's no official info on the car yet, but our sources state that the Sportback Concept will find its way into production as the A7 by mid-2010. And yes, it will be based on the A6 using the same powertrains, including the 3.0 TFSI turbocharged V6 and the RS6's twin-turbo 5.0-lter V10. Click through to see the leaked photos and tell us your initial thoughts.
