About Audi S8
The 2015 Audi A8 is the German luxury automaker's flagship sedan, meant to take on executive haulers like the Mercedes-Benz S-Class, BMW 7 Series and Lexus LS. The A8 has traditionally flown a bit lower on the radar compared to those 5-passenger high-end sedans, but it has more than enough power and pomp to play with the best. In addition to being the only full-size luxury sedan equipped with standard all-wheel drive, the A8 offers a variety of trims and two lengths, standard or the long-wheelbase A8 L. Several engines are also available, including a turbodiesel that earns the A8 class-leading fuel economy of up to 36 mpg or, at the other end, a 12-cylinder behemoth. For the performance-minded, the S8 takes this sedan to another level.
