Based on the all-new 6 Series, the 2006 M6 adds a touch of understated aggressiveness to BMW’s sleek four-passenger coupe. The front end features a unique air dam that acts to cool the large engine and cross-drilled brakes, whereas the muscular sides are accented by side gills in the fenders and distinct mirror housings. Fitted to the rear is a diffuser that helps maintain high-speed stability, and quad tailpipes. Of the seven available colors, four are specific to the M: Silverstone II, Interlagos Blue, Sepang Bronze, and Indianapolis Red.

Like most BMWs of the past several years, the 2006 M6’s rear end is of the tiered, bubble-butt variety. For those who find the look unpleasant, Fisker Coachbuild will soon be offering the Latigo CS, a rebodied 6 Series with a much more svelte tail.
