2016 Audi S6 Performance and Engine

Twin-Turbocharged V8 Power

Under the hood sits Audi's legendary 4.0-liter twin-turbocharged V8 — the same basic architecture shared with Lamborghini and Bentley platforms. In the S6, this engine produces 450 horsepower and 406 lb-ft of torque, delivering a 0-60 mph time of around 4.4 seconds. It's shockingly quick for a full-size luxury sedan, and the power delivery is smooth, linear, and relentlessly satisfying.
 

7-Speed S tronic Transmission and Quattro AWD

Paired to the engine is Audi's 7-speed S tronic dual-clutch transmission — a gearbox that shifts with razor-sharp precision in Sport mode and settles into smooth, unobtrusive behavior during everyday driving. Combined with Audi's legendary Quattro all-wheel drive system, this S6 delivers planted, confident handling in any driving condition — whether you're merging onto the 5 Freeway or carving through the canyons above Orange County. The Quattro system provides genuine driving security and inspires real confidence behind the wheel.
 

Audi S6 Prestige Features and Interior

What the Prestige Trim Includes

The Prestige is the pinnacle of the 2016 S6 lineup, and it shows. Expect a cabin loaded with Bang & Olufsen Advanced Sound System audio, Audi's MMI Navigation Plus with voice control, full LED headlights with dynamic turn signals, a panoramic sunroof, heated and ventilated front seats in fine Nappa leather, a heated steering wheel, and Audi's driver assistance suite including adaptive cruise control and lane departure warning. The interior quality is simply on another level — soft-touch surfaces, aluminum inlays, and sport bucket seats with S6 embossing make this feel like a proper driver's cockpit.
 

Technology at Every Turn

The 2016 S6 Prestige includes Audi Connect with available 4G LTE Wi-Fi, a rearview camera, parking sensors front and rear, and Audi's Multi Media Interface which was one of the more intuitive infotainment systems available in this era. It's a car that still feels modern and capable from a tech standpoint, even nearly a decade after production.
 

Audi S6 Reliability and Ownership

The 2016 Audi S6 has earned a reputation among enthusiasts as one of the most satisfying and rewarding German luxury sedans to own — provided the buyer goes in with eyes open about maintenance expectations. The 4.0-liter TFSI V8 features Audi's cylinder deactivation system, which shuts down four cylinders under light load to improve fuel economy. This system is generally dependable but benefits from regular oil changes with the correct specification oil. Carbon buildup on intake valves is a known characteristic of direct-injection engines like this one and can be addressed with periodic walnut blasting services.

Owners consistently praise the S6 for its blend of everyday livability and track-day capability. The adaptive air suspension, standard on the Prestige trim, delivers a composed and comfortable ride around town and firms up admirably when you want to push. At 151k miles, a well-maintained S6 still has plenty of life ahead of it — many owners report running these well past 200,000 miles with routine care. A pre-purchase inspection from a qualified Audi technician is always a smart step at this mileage.
