Overview
Although it’s based on the sober A6 sedan, the 2024 Audi S6 turns up the heat with a 444-hp twin-turbo V-6 and sharper handling. This more athletic version of the S6 feels much smaller than its mid-size shape when hustled through corners. Its powertrain packs a punch, too, hitting 60 mph in just 4.0 seconds at our test track. On the inside, the S6 is luxury-car rich, with high-end features such as massaging seats, fine materials, and impeccable fit and finish. A host of screens dot the S6’s dashboard, with two large ones serving as infotainment and climate controls, but if you’re not comfortable with touch-sensitive controls this setup may be a turn-off. The S6’s other fault is that it may be a bit too unflappable. It lacks the drama and difficult-to-rein-in nature of other sports sedans, such as our current favorite, the Cadillac CT5-V Blackwing.
What’s New for 2024?
The S6 adopts a new grille design for 2024 that features aluminum inlays with matching side vent accents and mirror caps. New LED headlamps further dress up the S6’s look and feature a new contoured daytime running light. Ascari Blue and Grenadine Red Metallic are new colors for the exterior, and the cabin can now be had with Olive Tree and Ash Volcanic Gray wood trims—or you can select microfiber trim instead.
Pricing and Which One to Buy
Upgrading to the Prestige model costs more but it unlocks a lot of features, including a hands-free driving mode, a head-up display, matrix-design LED headlamps, automatic high-beams, soft-close doors, a power-operated trunk lid, a leather-wrapped dashboard and center console, an in-cabin fragrance diffuser, and heated rear seats. We’d add the 19-speaker Bang & Olufsen stereo system and the cool night vision feature that helps identify animals and pedestrians in the dark.
Engine, Transmission, and Performance
While the last-generation S6 was powered by a throaty 450-hp 4.0-liter V-8, the 2020 model comes with a more complex powertrain. The standard 2.9-liter V-6 is twin-turbocharged and uses a 48-volt hybrid system to power an electric supercharger for additional boost. Altogether, the system pumps out a robust 444 horsepower. An eight-speed automatic and Audi’s Quattro all-wheel-drive system are standard. At our test track, the car leapt to 60 mph in 4.0 seconds; the S7—the S6’s shapelier counterpart—managed to blast to 60 mph in just 4.1 seconds. On curvy roads, the S6 proves to be a lovely partner. It disguises its size and feels sportier than we anticipated, especially with the optional rear-wheel-steering system.
Fuel Economy and Real-World MPG
As expected, the S6’s fuel economy has improved over the outgoing V-8 model’s. The new car earned EPA estimated ratings of 18 mpg city, 28 mpg highway, and 22 mpg combined—an increase of 2 mpg, 4 mpg, and 4 mpg, respectively, over the old V-8-powered S6. We haven’t had the chance to put this car through our 200-mile highway fuel-economy test, but the mechanically similar S7 delivered a 28-mpg result.

Interior, Comfort, and Cargo
Like that of the A6, the S6’s interior serves to highlight Audi’s tech-driven luxury ethos. The design is sleek and modern, highlighted by fine materials, soft leather, and genuine wood trim. Four-zone automatic climate control is standard, as are a power-adjustable heated steering wheel, adjustable ambient lighting, diamond-stitched leather upholstery, and 12-way power-adjustable heated front seats. Going with the top-spec Prestige model adds the Extended Leather package, which wraps the dashboard, armrests, and center console in supple leather. Though we haven’t tested the S6’s cargo capacity yet, we expect it will hold the same amount of stuff as the A6—that is, six carry-on suitcases inside the trunk and a total of 20 cases with the rear seats folded.
Infotainment and Connectivity
The S6’s dashboard is dominated by digital displays. The main 10.1-inch infotainment touchscreen rests above a secondary 8.6-inch display. The upper screen handles functions such as navigation, audio controls, and other entertainment features while the lower one provides access to vehicle settings, climate control, and the like. All S6 models come standard with Audi’s Virtual Cockpit digital gauge display and an onboard Wi-Fi hotspot. Apple CarPlay and Android Auto integration are also included.
Safety and Driver-Assistance Features
Like the A6, the S6 offers a host of standard driver-assistance features with more high-tech ones available as options. For more information about the S6’s crash-test results, visit the National Highway Traffic Safety Administration (NHTSA) and Insurance Institute for Highway Safety (IIHS) websites. Key safety features include:
- Standard automated emergency braking with pedestrian detection
- Standard lane-departure warning
- Available adaptive cruise control with hands-free driving mode
Warranty and Maintenance Coverage
If Audi’s standard warranty seems a little basic, that’s because is it. Rivals such as the BMW 8-series Gran Coupe and the two-door Lexus LC offer more value in the form of a complimentary scheduled maintenance program or longer powertrain warranty.
- Limited warranty covers four years or 50,000 miles
- Powertrain warranty covers four years or 50,000 miles
- No complimentary scheduled maintenance
