# 2001-2002 BMW Z3 M Roadster S54 The final iteration of BMW's Z3 M Roadster received the legendary S54 inline-six from the E46 M3, producing 315 horsepower—a substantial upgrade over the previous S52 engine. This swan-song model transformed the quirky roadster into a genuine performance weapon. Enthusiasts celebrate its raw, communicative driving experience, precise steering, and intoxicating engine note that revs eagerly to 8,000 rpm. The combination of compact dimensions and serious power creates an engaging, old-school sports car feel increasingly rare in modern BMWs. Critics note its controversial "clown shoe" styling (coupe version), firm ride, and limited practicality. The S54 is mechanically robust but requires diligent maintenance, particularly regarding VANOS systems and rod bearings. Today, it's ideal for driving purists seeking an analog, weekend backroad carver. Clean examples have appreciated significantly, making them collectible modern classics rather than daily drivers.
The S54-powered Z3 M Roadster requires expensive maintenance including VANOS system repairs ($1,500-3,000), rod bearing replacements every 60-80k miles ($2,000-4,000 preventatively), and subframe reinforcement ($1,000-2,000). Rear shock mounts commonly fail. Insurance rates are high due to performance classification. Parts are costly, but the S54 engine is generally reliable when properly maintained.
