The 2009 Audi A8 is separated from its competition thanks to its all-wheel-drive quattro system that comes standard. The A8 offers an especially distinctive, comfortable interior and strong lineup of high-tech interior convenience features, especially in the flagship W12 6.0L guise. The S8 pairs all of the A8's technological wizardry with the same V10 engine used in the Lamborghini Gallardo, making the S8 not only extremely luxurious, but also an excellent performer.
