The BMW Z3 M Roadster was the top of the line variant for the E36/7 Z3 Roadster. Introduced in 1998, the M Roadster featured a 3.2L inline six engine. Initially, the M Roadster was fitted with BMW's S50 engine (S52 in North America), but in late 2001, BMW fitted their updated, and more powerful S54 inline six engine. Regardless of engine, the Z3 M featured a 5 speed manual transmission that sent drive to the rear wheels. Built until 2002, the BMW Z3 M Roadster would eventually be replaced by the Z4 M Roadster in 2006.
