Audi A6

The A6 holds its own among luxury sedans. It got a new 300-hp, supercharged V6 engine and some minor cosmetic alterations. Handling remains responsive and secure, the seats are very comfortable, and the interior is beautifully finished. The new engine comes close to delivering the power of a V8 with the fuel economy of a V6. The ride is not as comfortable as it ought to be, though, and controls are needlessly confusing and difficult to use.
