Narrow headlights flank a large, five-pointed grille with a Mazda logo. The wheel arches and belt line are well defined. For 2007, Violet Gray and Smokestone are new colors, with the latter available only on the sedan and wagon.

Built on a 105.3-inch wheelbase, the Mazda6 sedan is 186.8 inches long overall. Base sedans get standard 16-inch tires, but all other editions ride on 17-inchers.
