Audi A7 breaks cover

This is Audi's new A7--the sleek, upmarket liftback previewed by the Sportback concept at the 2009 Detroit auto show. The A7 aims to provide the company with a stylish but practical rival to contemporary four-door luxury cars such as the Jaguar XF and the second-generation Mercedes-Benz CLS. Revealed at a gala presentation in Munich on Monday, the A7 is the second liftback model launched by Audi recently, following the smaller A5.
