The 2016 Audi S6 is a performance-focused variant of the regular A6 sedan, belonging to the fourth generation which was produced from 2011 to 2018. Powered by a potent 4.0-liter turbocharged V8 engine that makes 450 horsepower, the S6 sends this power through a seven-speed automated manual (S-tronic) transmission, and complements it with the brand’s surefooted Quattro all-wheel drive system. Inside, the S6 features a plethora of luxury appointments, superior build quality, and a packed technology roster. Tech highlights include Audi’s MMI infotainment system with navigation, 4G LTE data services, and a Bose surround-sound audio, all accessible via an 8-inch display screen. Safety features include antilock brakes, stability control, a rearview camera, and front and rear parking sensors, with options including night vision assist and adaptive cruise control. For 2016, the S6 received slight exterior revisions and improvements in horsepower over the previous year.
