About the 2015 Audi S8
3rd generation S8 (D4, 2013-2017), mid-cycle refresh year
Audi positions the S8 as a full-size luxury sedan that delivers very quick acceleration without looking overly dramatic. Its identity is the mix of strong V8 power, AWD traction, adaptive suspension, and a richly finished cabin with advanced comfort and technology features. Compared with rival high-performance luxury sedans, the S8 leans toward understated design, year-round usability, and a balance of quiet long-distance comfort with serious speed.
The 2015 S8 is a full-size luxury sedan that blends a discreet appearance with serious performance. Its twin-turbo 4.0-liter V8, adaptive air suspension, and AWD support the performance side, while 22-way heated, ventilated, and massaging front seats, four-zone climate control, and a 14-speaker Bose audio system give it a highly equipped cabin.
