Two M54 engine variants will be added to the E39 for the 2001 M.Y. starting production
9/00. The M54 B30 and M54 B25. The M54 B30 engine will replace the M52 B28TU of
the 528i and become the 530i. The M54 B25 engine equipped 5 Series will create a new
model, the 525i, it will become the entry level 5 series.
The design objectives for the M54 engine were:
• Lower emissions
• Maintain fuel economy
• Increase power and performance.
The 540i/it will use the A5S 440Z automatic transmission with Steptronic as standard
equipment and continues to have the optional 6 speed manual. The 525i and 530i
models will use the A5S 390R (GM 5) with Steptronic as optional equipment until March of
2001 at which time the GM5 will be replaced by the A5S 325Z (5HP 19).
