2021 Audi S6: What's New, Specs & Features
Last updated August 4, 2026
The most important change for the 2021 Audi S6 is that its upgraded digital instrument cluster becomes standard across the lineup. This is a light equipment update, not a redesign, and the powertrain and body carry over from 2020.
About the 2021 Audi S6
Fifth-generation S6 (C8), second U.S. model year after the all-new 2020 redesign.
The 2021 S6 is Audi's understated performance midsize sedan. Its appeal is balance: strong twin-turbo V6 power, standard quattro all-wheel drive, a quiet upscale cabin, and a tech-heavy dashboard, all wrapped in a sedan that does not look as loud or aggressive as some rivals. For most shoppers, it is the choice for fast daily driving, year-round traction, and premium comfort without giving up subtle styling.
The 2021 S6 is a performance-focused luxury sedan offered in Premium Plus and Prestige trims. Both use a 444-hp twin-turbo V6, an eight-speed automatic transmission, AWD, and adaptive air suspension; Prestige adds features such as adaptive cruise control, lane support, a head-up display, heated rear seats, and soft-close doors.
