The A6 is often forgotten when thinking of mid-sized executive sport sedans. After undergoing a redesign in 2009, little changes for ’10. The 3.2-litre FSI V6, 3.0 TFSI V6 and 4.2 FSI V8 cover a broad spectrum of outputs, but as in other Audi products, the V8 feels outgunned by the newer supercharged V6. Quattro all-wheel-drive is standard, along with a six-speed automatic transmission. Inside, the A6 still impresses with its detailing, materials and quality construction. New Special Edition package adds all the tasty bits together on the 3.0T.
