There is much to love about the A6. Its cabin is airy and comfortable, with firm, supportive seats. Its styling is crisp, clean and modern, though the front is dominated by a massive and controversial grille.

Underway, the A6 boasts sharp, precise steering, and a firm ride. In high-speed corners the quattro models feel like they're on rails, one of the benefits of Audi's superb all-wheel-drive system. Braking and handling are excellent, whether on dry pavement or when hurtling through a torrent of rain.

V6 and V8 versions are available. The well-equipped V6 model delivers brisk acceleration, while the V8 qualifies the A6 as a high-performance sports sedan. The S6 is for serious drivers who don't mind trading comfort for performance.

Most cars are redesigned every five years or so and this latest-generation A6 was launched as a 2005 model. It's larger and roomier than the previous-generation version, and features dramatically changed styling.

What's new for 2007: a more powerful V8 engine for the A6 4.2 and the introduction of the high-performance S6.
