BMW M Roadster

This car is based on the BMW Z3 and the M Coupe. European M Roadsters built 1998 to 2001 had the same engine (S50) that powered the 1995 to 1998 M3 Evo with 321 bhp and 350 Nm (258 ft·lbf). North American M roadsters built from 1998 to 2000 had the 3.0L S52 engine (based on the regular M52 engine) with 240 hp and 320 Nm (236 ft·lbf). In 2001 BMW revised the M Roadster with the 3.2L S54 engine. This was the highest specific output naturally aspirated production engine ever made by BMW (not counting S70/2 GTR LM engine from the McLaren F1 LM) when it was applied in the M3. In M Roadster form it produced 325 bhp (320 hp) and 353 Nm (261 ft·lbf) of torque. BMW only produced the S54-based M Roadster for two years, discontinuing it after the 2002 model year.
