Last updated August 4, 2026

About the 2021 Audi S5
2nd generation (B9, US-market 2018-2024), second year after the 2020 refresh.
Audi positions the S5 as the more emotional, design-led performance version of the A5 family. It blends strong turbo V6 power, standard all-wheel drive, and an upscale cabin with more style than the mechanically similar S4. The appeal is everyday usability with real speed: buyers get luxury-car comfort, secure year-round traction, and a choice of sporty coupe, practical Sportback, or open-top Cabriolet body styles.
The 2021 S5 remains a sporty luxury model offered as a coupe, Sportback, or convertible, all with a 349-hp turbo V6 and standard all-wheel drive. Premium covers the essentials, while Premium Plus adds a 12.3-inch digital instrument display, adaptive cruise control, and a surround-view camera. Prestige focuses on luxury technology with a head-up display, navigation, premium audio, upgraded lighting, and automated parking.
