Audi's A7 belongs to an emerging class of four-door luxury cars styled to resemble coupes. It's an exclusive club that includes the likes of the Porsche Panamera and BMW 6-Series Gran Coupe.
The overall effect is dramatic as these cars swap the formal roofline of a sedan for a sporty fastback look. This often reduces rear headroom, but sometimes creates more versatile cargo space.
All-new for 2012, the A7 enters its sophomore season essentially unchanged. At the heart of its appeal is Audi's Quattro all-wheel drive system and a supercharged 3-liter V6, which gives the A7 V8-like performance.
