The E46 generation of BMW M3 was introduced for the 2001 model year. This latest M3 was part of the E46 3 Series and was powered by BMW's S54 3.2L straight six engine, which produced 338hp. Two body styles were built, a coupe and a convertible. These body styles were offered with two transmission options, leading to four main variants being built: Coupe Manual, Coupe SMG, Convertible Manual, and Convertible SMG. Other notable E46 M3 variants included the M3 Competition Package (ZCP), which was built in Manual and SMG versions, and the M3 CSL. In production until 2006, the E46 BMW M3 was replaced by the E90 BMW M3 for 2007.
