Highlights of the Detroit Motor Show

Audi A8
A full-size luxury sedan more than 16.8 ft. long, this Audi is powered by a V-8 engine and enhanced by a lengthy list of electronic features, like radar to help during lane changes. The restyled 2011 A8 is the new flagship of Audi's fleet of expensive cars. It is built on an aluminum space frame, and its big engine is equipped with direct injection so it consumes 27% less fuel. The car also uses ultra-efficient LEDs both inside and out.
