The 2009 Audi S8 is the sport version of the flagship Audi A8. The 2009 Audi S8 is a carryover from the 2008 Audi S8 and uses the same 5.2L V10 which produces 450 horses. This is the same engine used in the Audi S6 and its cousin, the Lamborghini Gallardo. The S8 has one transmission available and that is the 6-speed Triptronic automatic. The Quattro AWD comes standard. The Audi S8, like other S models in the Audi lineup, features more aggressive suspension, wheels, tires, exhaust, and styling, which all add up to a more thrilling driving experience when compared to the plush Audi A8. Options on the 2009 S8 include radar-controlled adaptive cruise control, sunshades, a powered trunk lid, heated rear seats, a rearview camera, Sirius satellite radio, power door close assist, and full leather interior. The 2009 Audi S8 is a great alternative in a world where most people gravitate to the BMW 7-series and the Mercedes S-Class. This is the perfect car for ski-trips with the family, thanks to the Quattro AWD, or blasting down the highway, thanks to the 450 hp V10 and S-tuned suspension.
