2003 BMW M3
BMW made a limited run (less than 1,400 units) of the M3 CSL (E46) machines between June and December 2003. The CSL (Coupe Sport Lightweight) received an aggressive weight reduction campaign, more power (up to 380 hp), and sharper handling characteristics than the standard M3, courtesy of larger anti-roll bars, stiffer spring rates, and semi-slick racing compound tires (Michelin Pilot Sport Cups). From the exterior, the CSL is distinguished from its standard sibling with a different wheel design, larger integrated rear spoiler and a large air intake hole on the left side of the front bumper. Weight loss was achieved through use of a carbon-fiber roof, trunk lid made of sheet molding compound, lighter exhaust manifold, thinner rear glass, carbon fiber front bumper, rear diffuser, interior door panels and console, lightweight racing seats, removed sound insulation, and the removal of side air bags. The M3 CSL's engine differs from the M3 with different camshafts, carbon-fiber intake manifold and alpha-N engine management. Several other features available in a regular M3 as standard such as air conditioning and radio were also deleted, although these options could be added at the request of the owner. SMG II sequential manual gearbox was made standard. Owing to the small production run and the complications and expense of clearing DOT and EPA standards for the North American market, BMW never exported the CSL to the United States, although some parts from it were later made available on the regular M3 as part of an optional Competition Package.
