Most vehicles 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. If you believe the best time to buy a new car is in its second year of production, then the time to buy the A6 is now. The newest generation of vehicles typically have the latest in safety features and engineering, and some studies suggest quality is higher in the second year of production because the bugs have been worked out.

For 2006, the A6 lineup has been filled out to include an Avant, or wagon, as well as a new front-wheel-drive model.

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 grille that's somewhat controversial. There's nothing controversial about the driving experience, however. 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 hurdling through a torrent of rain.

V6 and V8 versions of the A6 are available. The well-equipped V6 model delivers brisk acceleration performance, while the V8 qualifies the A6 as a high-perforance sports sedan. Either way, the Audi A6 deserves consideration by anyone shopping for a luxurious sports sedan in its price range.
