The 2009 Audi A8 is a full-size premium luxury sedan loaded to the brim with the company's latest technological advances. More than just a showcase for Audi design and engineering, the A8 serves two masters: The driver and the chauffeured. Every bit the equal of such makes as the Mercedes-Benz S-Class, BMW 7 Series and Lexus LS, the A8 appeals to those who have the cash, but might prefer not to flaunt it quite so much. The A8's subtle styling is alluring without being flashy, a traditional design that stands the test of time long after other cars have become dated. Offered in regular or extended wheelbase versions, and with a choice of a V8 or the proven W12 engine, the A8 is all about style, sophistication and success.
