Both sports saloons and estates are available. It’s best known for its refined V6 diesel engine, advanced technology and refined looks. The Audi S6 is designed for those who want sports-car pace without missing out on space and practicality. As part of the performance line-up based on the A6, the S6 has gone through several generations. Models built after 2019 feature a high-performance 3.0-litre V6 diesel with mild-hybrid technology. The S6 competes with the BMW 5 Series 540d and Mercedes-AMG E 53, distinguishing itself with a blend of strong acceleration, high-grade interiors and quiet efficiency. Recent S6s come well equipped with state-of-the-art features, such as Audi’s Virtual Cockpit and adaptive suspension, so they feel suitably luxurious for the class. This is a compelling choice for drivers seeking comfort and speed in one subtly stylish package.
Impressive acceleration – the saloon does 0-62mph in five secondsGrippy on winding back roads, thanks to Quattro AWDSpacious cabin and boot, with plenty of legroom
Choice of driving modes is unnecessarily complexHigh purchase and running costs Some rivals offer easier-to-use infotainment systemsThe Audi S6 comes standard with a strong selection of safety features, including multiple airbags, stability and traction control, and ISOFIX child seat mounts. Advanced driver aids such as parking sensors, a rear-view camera, and auto emergency braking are available. Higher-spec models may add adaptive cruise control, lane-keep assist and traffic sign recognition.
For recent models from 2019 onwards, the S6 is powered by a 3.0-litre V6 diesel engine with mild-hybrid tech, delivering 344bhp. Pre-2019 models can be found with petrol V8 engines, including a twin-turbo 4.0-litre version. All feature Quattro four-wheel drive and an automatic gearbox.
Most feature the Virtual Cockpit digital display, a 10.1-inch main infotainment touchscreen. Expect navigation, DAB radio, Bluetooth, wireless device charging, Android Auto and Apple CarPlay. There’s also a secondary screen for climate and other settings, with higher trims adding premium sound, head-up display and more advanced driver assists.
The 3.0-litre V6 diesel S6 can achieve around 36.2mpg on the official WLTP cycle. The older petrol S6s return around 24mpg, so running costs are higher. Real-world figures may vary depending on driving style, especially given this car’s performance potential.
Check for a full service history and signs of careful maintenance, as neglect of performance cars can be costly. Listen for odd sounds from the suspension or brakes and test all tech features in the cabin. Due to its power, inspect tyres and brakes for excessive wear. It’s always wise to get a professional appraisal like The AA Vehicle Inspection.
The S6 enjoys a solid reputation, though complex engines and electronics can mean higher repair bills if issues arise. Although Audi lags behind BMW and Mercedes according to owner surveys, these are generally reliable cars. Routine servicing and proper care can help ensure they stay that way.
