2022 Audi S6 Review

Think of the S6 as an A6 on steroids. Structurally the two cars are the same, but the S6 comes with only one high-performance engine option — a twin-turbocharged 444-hp 2.9-liter V6. Audi also upgrades the S6 with height-adjustable air suspension, though a conventional coil-spring suspension is optional. Every S6 is equipped with all-wheel drive and an eight-speed automatic transmission. Like its abridged-roof stablemate, the S7, the S6 comes outfitted with a pile of tech features. Most obvious are the twin screens that dominate its dashboard and control all the climate and infotainment functions. But it's the S6's design and materials that make it special. Supple leather in a variety of colors and striking wood inlays make for a modern and clean interior presentation that's distinctly Audi.

BMW's M550i, the Mercedes-AMG E 53 and even Cadillac's CT5 V Blackwing are worth considering in this class. All of the German competitors are all-wheel-drive and offer similar if not slightly better performance. And they all cost about the same as the S6. So does the CT5-V Blackwing, but it's a rear-drive monster with 668 horsepower from a supercharged 6.2-liter V8. Go, America! Read our Expert Rating for all the details on the S6.

Based on the standard A6, the S6 is a higher-performance version of Audi's midsize sedan. It offers more power from its twin-turbocharged 2.9-liter V6 (444 horsepower, 443 lb-ft) as well as an eight-speed automatic transmission with paddle shifters. All-wheel drive is standard. It's available in two trim levels, Premium Plus and Prestige.
