2015 Audi S6: What's New, Specs & Features
Last updated August 4, 2026

The biggest change for the 2015 Audi S6 is better standard equipment: full LED headlights and a head-up display became standard. It is otherwise a light update, with the same twin-turbo V8, all-wheel drive, and basic design as the 2014 model.
About the 2015 Audi S6
4th generation S6 (C7, 2013-2018), pre-refresh year; 2015 is the last U.S. model year before the 2016 facelift.
Audi positions the S6 as a high-performance luxury sedan that blends V8 speed, all-weather traction, and daily-driver comfort in a body that looks more understated than many rivals. The OEM emphasis is on luxury plus power: strong acceleration from the twin-turbo V8, quattro grip, adaptive air suspension, and a richly finished cabin with sport seats and major tech already built in. It is meant to be fast and polished in equal measure, not a stripped-down track special.
The 2015 S6 is a performance-luxury sedan that blends strong acceleration with executive-car comfort. Its 420-hp twin-turbo V8, all-wheel drive, adaptive air suspension, and sport differential support its performance side, while heated Valcona leather sport seats, navigation, and a head-up display give the cabin an upscale feel.
