Audi's all-aluminum flagship will be redesigned for the 2011 model year. Styling follows Audi's trend towards more angular lines, while all-LED headlights denote the A8's top-of-the-line status. The electronics are more advanced than ever, and the US version of the A8 will feature a more powerful version of the familiar 4.2 liter direct-injected V8 with a new 8-speed automatic transmission.
