2015 Audi S8

The 2015 Audi S8 is one of GAYOT's Top 10 Luxury Sedans

With 520-horsepower on tap from its 4.0-liter turbocharged and direct-injected V8, this mammoth sedan has the speed to match its size. Refreshed slightly for 2015, the flagship Audi, constructed primarily from aluminum, mates elegance with excess in a high-performance, surprisingly agile sedan. With quattro all-wheel drive standard along with a limited-slip rear differential, the S8 handles curvy roads like a much smaller sports sedan. Though our test car's optional 21-inch wheels with 275/35/R21 summer tires compromised ride quality a little bit, it was a trade-off we'd gladly make for handling and road-holding unlike anything else in this class.

The 2015 Audi S8 also features one of the most elegant and inviting interiors in a car. Befitting the sedan's hotel-on-wheels mission, the seats are supremely comfortable, noise is nearly nonexistent, and all surfaces are high-quality and pleasing to the touch. Our Moonlight Blue Metallic press car featured the $5,500 Audi Design Selection, which added full leather dash surfaces, a glossy piano black glaze to the shift knob and black Alcantara headliners. We also sampled the optional Bang & Olufsen sound system with its trick retractable tweeters, a fun touch.
