Who says that three times is the charm? The Audi S6 begs to differ, a car entering its fourth generation. If speed is what you are after, look no further because this compact sedan delivers. The upgraded twin-turbocharged 4.0-liter engine offers a resounding 420 horses, but is not as fast as the V10 that was featured in the third generation edition. With 406 pound-feet of torque, there are few other cars in this class that can beat you pound-for-pound on any given Sunday. You’ll take heart with the comfy 7-speed auto-clutch with all-wheel drive, something that will give you plenty of shifting to do when cleaning house off the line. The adaptive air suspension (which can be sport-tuned optional) literally glides the car like it’s floating on air. Two popular, and equally as pricey, interior packages exist, with some minor differences between the already luxurious interior and the prices they are being offered at. You’ll love the rolling Wi-Fi, night vision, sports-tuned ceramic brakes that can stop on a dime and LED headlights that can actually adapt to different conditions. The built-in seat massagers are helpful but not really worth the maintenance. A voice and hand-recognizing GPS system is a little over the top. Then again, you get what you pay for.Read more Read less
For 2015, the Audi A6 gets standard 18-inch wheels and headlamp upgrades across all trims; HID headlamps for the Premium and Premium Plus while Prestige trims get advanced LED headlamps.
Stylish interior; strong performance; advanced safety features; MMI Touch interface; magnificent high-end audio systems; impressive fuel-efficiency from TDI diesel
The 2015 Audi A6 is a mid-size luxury sport sedan that offers strong performance while also delivering all-weather confidence and good gas mileage. Interior and backseat space are also a bit better than in other rear-wheel-drive European sport sedans, and the interior appointments themselves stand out as more fashion-forward. Audi claims best-in-class fuel economy for the 2.0T model, which achieves up to 25 mpg city, 33 highway. The TDI clean diesel offers even more impressive fuel economy, with returns of 24 mpg city and 38 mpg highway. Advanced technology--whether for safety, information, or entertainment--is where the A6 really shines. It offers blind-spot monitors, a night vision system, a head-up display, parking sensors, adaptive cruise control and other leading-edge safety features. The A6 is also ahead of the curve with its excellent MMI Touch system, which includes a simplified interface and a scratch-pad controller that accepts input addresses by tracing individual letters. Meanwhile, the S6 remains a performance standout, with performance capable of propelling it to 60 mph in just 4.8 seconds.
