BMW chooses not to attract undue attention to the 2006 M6’s impressive performance potential, opting instead for subtle design changes to mark the car as distinct from the 6 Series. For starters, the M6’s body is lighter through the use of aluminum, plastic, and sheet-molded compound body panels. In combination with its all-aluminum chassis and suspension, the 2006 BMW M6 boasts a power-to-weight ratio of seven pounds per horsepower, as well as a 53.5/46.5 front/rear weight distribution. Additionally, the front and rear fascias are unique to the M6, the side sills and rocker panels have a bolder design, and the roof is carbon fiber. Satin chrome window trim, M-design side mirrors, and four stainless steel exhaust outlets are also part of the package, and the M6 can be painted in several colors, four of which are exclusive to M-badged models. Clearly, though, the M Double Spoke wheels and the M badges are the most obvious tip-offs that this variant of the Six is the M6 and not the 650Ci. For now, the M6 is only available as a coupe, but a convertible is on the way.
