2020 Audi S6: What's New, Specs & Features
Last updated August 4, 2026
The 2020 Audi S6 returns to the US as an all-new, C8-generation sedan after skipping the 2019 model year. Its headline change is a 444-hp twin-turbo 2.9-liter V6 with 48-volt mild-hybrid assist, replacing the previous generation’s V8.
About the 2020 Audi S6
C8 generation, first US model year for this S6 sedan; the prior US S6 ended with 2018 and there was no 2019 S6 sedan.
Audi positions the S6 as a luxury sports sedan that mixes serious speed with everyday usefulness. The appeal is understated rather than flashy: strong acceleration, standard all-wheel drive, a quiet upscale cabin, and the latest cabin tech from the redesigned A6, all wrapped in a sedan that still works as a daily driver. It stands out from rivals by pairing Audi’s restrained styling with real performance and all-weather confidence.
Audi positioned the 2020 S6 as a quick but understated luxury sedan suited to everyday driving. Premium Plus has adaptive air suspension, heated leather sport seats, navigation, dual touchscreens, and a 12.3-inch digital instrument display. Prestige keeps the same performance hardware and adds features such as adaptive cruise control with lane-centering assist, a head-up display, quieter glass, soft-close doors, and heated rear seats.
