2010 Audi A6

Quattro All-Wheel Drive
For negotiating curvy canyons or snowy streets, Audi's famed quattro all-wheel-drive system (available on 3.0 and 4.2 trims only) gives the A6 a real advantage.

Multi Media Interface
Although it subjects its operator to a learning curve, Audi's MMI system is a sleek solution for the control of in-cabin technology.

From the driver's seat, the A6 comes across as one serious sedan. Leather surfaces are inviting, though seats are on the firm side. They're satisfying for long-term touring, however, with helpful but not intrusive support and bolstering. Backseat riders get plenty of headroom and knee space, but the center passenger must suffer the indignity of a stiff perch and a high floor hump. Fully calibrated gauges are especially easy to read, though the MMI (Multi Media Interface) control can be a handful. Don't expect an unobstructed view over the left shoulder, but visibility is good otherwise. An electronic dashboard button opens a glove box that is short on space.

The new look of Audi is evident across the A6 body. Up front, a bold trapezoidal grille – tall and split into two elements – is flanked by available xenon headlamps and cool LED daytime running lights; LEDs also comprise the rear taillights. Designer Achim Badstubner says it's the kind of dramatic front end that promises "overtaking prestige on the Autobahn," informing drivers who see it coming in the rearview mirror that a serious machine is on its way.

While the newly improved 3.2-liter V6 is more than sufficient to move the A6, the few extra dollars spent on the 3.0-liter supercharged engine is probably well worth it. It's simply a matter of how quickly you wish to be moved, and how important it is to have quattro all-wheel drive underfoot. The 3.2-liter V6 is smooth, quiet and refined, delivering excellent low-end torque for quick starts, as well as respectable highway fuel economy, but it's only offered with front-wheel drive. The V8 turns the A6 from quick to remarkably quick, but you'll pay a premium at both the dealership and the gas pump.
