Design, development and variant notes
The M54 has an aluminium block with iron liners, double-VANOS, DISA intake, electronic throttle and Siemens MS43 management. The North American M54B30 ZHP version used revised camshafts and calibration.
The S54 is more closely developed from the S50 than the M54 and has an iron block. Wikipedia identifies MSS54 management, with MSS70 in the later Z4 M; S54B32HP is the higher-output M3 CSL version.
