The S6 is the high performance version of the Audi A6 sedan. Better performance means a 5.2-liter V10 producing 425 horsepower and a combined fuel economy of 16 mpg. The Quattro all-wheel-drive system and Tiptronic automatic six-speed transmission are standard as well. Inside, you'll find the latest Multi Media Interface (MMI) which controls entertainment, communication, and optional navigation features via the dash-mounted LCD screen and other center console-mounted controls.

While not a perfect system (and easier to use than BMW's iDrive system), it has been improved significantly for 2010. Another cool new feature is real-time traffic information - surely necessary in everyday work commutes. If the $76,100 base price is something you can manage, then be sure to take the S6 out for a spin when considering your next high performance luxury sedan. Audis rarely disappoint.
