The 2007 Audi S8 is a luxury high-performance sedan from the German automaker's flagship A8 series. The S8's power primarily comes from its 5.2L V10 engine that generates a whopping 450 horsepower. A six-speed automatic transmission routes power to all four wheels (all wheel drive), assuring a guaranteed grip under all driving conditions. It comes swathed in premium materials including Valcona leather seats with Alcantara inserts. The tech department isn't slack either—the S8 is equipped with Audi's MMI (MultiMedia Interface) which provides navigation, audio, and climate control settings via a pop-up 7-inch color screen. On the safety front, features include stability control, anti-lock brakes, and a full complement of airbags. The Bi-Xenon adaptive headlights swivel to illuminate corners as the car's electronic brain commands.
