2018 Audi S6: What's New, Specs & Features
Last updated August 4, 2026
The 2018 Audi S6 was mostly a carryover, with LED headlights becoming standard on the Premium Plus trim. Its 450-hp twin-turbo V8, standard all-wheel drive, two-trim lineup, safety features, and infotainment system otherwise continued without major changes.
About the 2018 Audi S6
C7.5 generation (facelifted C7), final U.S. model year before the 2020 redesign.
The 2018 Audi S6 is a fast, understated luxury sport sedan for drivers who want serious speed without a flashy look. Audi’s pitch is the blend: twin-turbo V8 power, standard all-wheel drive for year-round grip, a roomy five-seat cabin, and high-end materials that make it easy to use every day. Compared with louder rivals, the S6 leans more toward discreet style, strong traction, and an upscale interior than attention-grabbing drama.
The Premium Plus delivers the core S6 experience with a 450-hp twin-turbo V8, all-wheel drive, diamond-stitched leather sport seats, navigation, Apple CarPlay, Android Auto, and Bose audio. The Prestige uses the same performance hardware but adds a head-up display, surround-view cameras, a power trunk lid, and rear sunshades for greater everyday convenience.
