From a design perspective, the M Coupe looks much like the updated 2006 BMW Z4 M Roadster, a model accented by revised fog lights and air inlets, the BMW signature kidney grille, and a tail marked by reworked taillights and a sharper body line. However, the coupe adds 11 pounds and an arched hatch that incorporates a subtle spoiler, under which resides a 10.6-cubic foot cargo area. Five-spoke, 18-inch alloy wheels are unique to the M model and wear 225/45 high-performance tires up front, with 255/40s fitted to the rear. Other M exclusives include chrome dual exhaust pipes, a rear diffuser, and white gauges with red needles.
