Our Take

from the Cars.com expert editorial team

Vehicle Overview
The S6 is a high-performance version of Audi's A6 sedan, which is covered separately in the Research section. While the A6 employs V-6 or V-8 power, the S6 has a 435-horsepower V-10. Both cars were lightly restyled for 2009. Competitors include the BMW 5 Series, Mercedes-Benz E-Class and Infiniti M.

The S6 packs a standard six-speed automatic transmission and Quattro all-wheel drive. The S6 comes only in one trim level, Prestige.


Exterior
The S6 looks the part of a gussied-up A6, with bumper-mounted LED lights in place of the A6's lower fog lights. Unique front and rear bumpers and aluminum trim on door- and windowsills complete the package.

The most distinct visual changes between 2008 and 2009 versions of the A6/S6 are in back. The trunk gets new chrome accents, and the taillights drop the '08 model's squared-off design for something closer to the new A4's: They're wider and carry around to the trunklid.

The S6 comes standard with 19-inch wheels.


Interior
Besides unique leather seats with S-line logos and thicker side bolsters, the S6's wraparound cockpit sees few changes from the A6's. The S6 does come loaded, though, with standard heated leather upholstery, power front seats, a moonroof and a navigation system; a Bose stereo with a six-CD changer and full iPod/USB compatibility also are standard.

Audi's Multi-Media Interface places a control knob with a few shortcut buttons around it ahead of the center console. Like B...

Audi's Multi-Media Interface places a control knob with a few shortcut buttons around it ahead of the center console. Like BMW's iDrive and Mercedes-Benz's Comand, MMI governs various navigation and stereo functions through a central dashboard display. A third-generation MMI system is in store for the 2010 A6/S6, with improved graphics and better usability.

The short list of options includes heated rear seats and carbon fiber interior trim.


Under the Hood
The S6 is stoked by Audi's first-ever V-10 engine, a normally aspirated (not turbocharged, not supercharged) 5.2-liter with direct injection. It combines the generous torque characteristics of a high cylinder count with the high-rev output of a 7,000-rpm redline, delivering 398 pounds-feet of torque at 3,000-4,000 rpm (with 90 percent on tap at 2,300 rpm) and 435 hp at 6,800 rpm. Audi cites a zero-to-60-mph time of 5.1 seconds, a quarter-mile time of 13.4 seconds and a top speed electronically limited to 155 mph.

The S6's Quattro all-wheel-drive system sends 60 percent of the torque to the rear wheels as a default, and up to 85 percent when called upon. The previous generation of Quattro for both cars split the torque 50/50, front/rear. The change gives the Audis equipped with the new Quattro dynamics closer to those of a rear-wheel-drive car.


Safety
Both the A6 and S6 are rated Top Safety Picks by the Insurance Institute for Highway Safety, thanks to their top performance in frontal-, side- and rear-impact crashes.

In addition to the required frontal airbags, the S6 includes seat-mounted side-impact airbags for the front passengers, and side curtain bags that deploy along the front and rear side windows. Antilock brakes, traction control and an electronic stability system are also standard. Seat-mounted side-impact airbags for the backseat are optional, as is a blind spot warning system.

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
