Audi's midsize S6 sedan is the company's high-performance midsize luxury sedan. It sits in the same big power company as the BMW 550i, Lexus GS F, and the Cadillac CTS V-Sport. It's the oldest model in that group, but it gets some updates for 2016 that include an extra 30 hp for the twin-turbo V8 that brings the total to a nice, round 450 hp. That power runs through a seven-speed dual clutch transmission and Audi's quattro all-wheel drive. The quick-shifting seven-speed is possibly the best gearbox in the class.
Along with the revised engine is a revised interior. The updated MMI infotainment system is one of the best in the business. The rest of the interior is extremely well finished, although as with many Audis the design can look somewhat cold at times.
Amongst its fellow super-sedans, the Audi excels at straight-line speed and an exceptionally smooth ride (especially next to the track-tuned Lexus GS F) thanks to its air suspension. It's the long-distance cruiser of the group, but the S6 falls short in the handling department when the roads get twisty.
The S6 comes in just one trim level, but that is very well equipped. There are LED headlights, sunroof, motion-open trunk, and sunshades for the rear windows. It has a surround view camera, automatic high beams, and self-parking. The seats are heated both front and rear, with the front occupants getting eight-way adjustable sport seats. There is four-zone climate control to keep all passengers comfortable. The MMI infotainment system is attached to a 14-speaker Bose stereo with satellite radio. It also has 19-inch wheels and a power-adjustable steering wheel.
Optional equipment includes a Driver Assistant package that adds pre-sense collision detection, active lane assist, and stop and go capable radar cruise control. A front seat package adds 14-way power adjustable front seats trimmed in Valcona leather and with a massage function.
Fuel economy is not likely a priority for buyers of a twin-turbo V8, but the S6 is estimated to achieve 13.3 L/100 km city and 8.8 highway.
