The E85 Z4 M Roadster (2006-2008) paired a hand-built 3.2L S54 inline-six, shared with the E46 M3, with a six-speed manual in a compact, rear-drive roadster body. It added a stiffer chassis, limited-slip differential and M-specific suspension, delivering around 343 hp at 7,900 rpm. It is the only Z4 with a true M engine and a sought-after analogue sports car.
The high-revving S54 is one of BMW M's finest engines, and its use in a lightweight open two-seater gives a raw, mechanical driving experience that modern turbocharged cars rarely match. Low production numbers and a manual-only specification have cemented its standing as a future classic.
