A high-performance Z3 model was introduced by BMW in 1998, the M Roadster.
Apart from the more powerful engines - 3.2L units borrowed from the updated M3 models delivering 321 hp - the new M Z3 Roadster featured a redesigned exhaust system, an aerodynamic body shape, revised braking and a new transmission. This model was available for both European and North-American. The US-sped models received an engine update in 2001, being fitted with a powerful 315-hp 3.2L S54 unit and a 5-speed manual transmission. The BMW Z3 M Roadster was discontinued in 2002, after it was produced in about 15,000 units.
