- High-performance version of the A6 sedan
- Twin-turbocharged 4.0-liter V-8 engine, making 420-hp
- 0-60 mph in only 4.5 seconds; Quattro all-wheel drive is standard
The 2014 Audi S6 is the high-performance version of Audi’s midsize A6 luxury sedan, adding more power and performance to a package that was already high on refinement and comfort.
The S6 is targeted squarely at the performance versions of competitor’s midsize luxury sedans, like the BMW 550 and Mercedes-Benz E550. There are not many changes for the S6 this model year, only the addition of an exterior package that adds black paint, trim pieces, and unique 20-inch wheels. Stylistically, the S6 shares pretty much all of the same DNA as the A6; the basic profile and shape of the two cars is identical, as are the dimensions. The S6 just takes the A6’s concept and sharpens it from certain angles, with added side sills, more aggressive looking air intakes up front, and quad exhaust tips in the rear. Adaptive xenon HID headlights with LED accents are standard, with a full LED headlight setup optional.
Under the hood is a 420-hp, twin-turbo 4.0-liter V-8 that makes 406 pounds-feet of torque and is mated to a seven-speed dual-clutch automatic transmission. Audi’s Quattro all-wheel drive system is standard for added traction. Even on performance machines, fuel economy is now a factor with rising fuel prices so it features cylinder deactivation technology, helping the S6 return an estimated 17/27 mpg city/highway. Keeping things steady on the road is a standard adaptive air suspension which can adjust the ride height for different scenarios.
Inside, the S6 combines Audi’s usual dexterity and aptitude for constructing high-quality interiors and adds more standard features on top of the A6. Every S6 comes with leather upholstery, bolstered sport seats to keep you in place during cornering, quad-zone automatic climate control, sunroof, and Bluetooth connectivity. Also standard is Audi’s MMI system, which has a touchpad on top of the controller that can accept letters/symbol inputs drawn by hand, making entering destinations or other operations a breeze. Optional features include satellite navigation, Bang and Olufsen sound system, and HD radio.
The 2014 S6 got a full five-star overall crash test rating from the NHTSA, the highest possible. Standard safety features include eight airbags, four-wheel antilock disc brakes, and an electronic stability system with traction control. There is also a long list of available safety technology, including adaptive cruise control, forward collision warning, night vision with pedestrian detection, and blind spot monitoring.
