2017 Audi S8: What's New, Specs & Features
Last updated August 4, 2026
The biggest change for 2017 is that Audi consolidated the U.S. S8 lineup into one higher-output configuration. The separate Plus trim name disappeared, while the sole S8 carried the 605-horsepower setup; otherwise, this was a light-update year.
About the 2017 Audi S8
3rd generation S8 (D4/D4.5), late-cycle year; 2017 is the first full U.S. model year sold only in the higher-output S8 setup.
The 2017 S8 is Audi’s full-size performance luxury sedan for buyers who want very high speed without giving up comfort, quiet cruising, and a richly finished cabin. Its identity is the mix of a powerful twin-turbo V8, standard all-wheel drive, and executive-sedan luxury. Compared with rivals, it stands out by pairing understated styling with very serious straight-line performance and confident all-weather traction.
The 2017 S8 is a discreet, high-performance luxury sedan with a twin-turbo 4.0-liter V8, an eight-speed automatic transmission, and standard all-wheel drive. Its luxury equipment includes massaging front seats in diamond-stitched leather, navigation with handwriting input, a 14-speaker Bose audio system, and a head-up display. Blind-spot monitoring, a 360-degree camera system, and a rear collision-preparation system add driver assistance.
