The M54B22, the junior engine in the M54 series (which also includes the M54B25, M54B30, and S54B32), is an evolution of the M52TUB20. It has a new cast iron crankshaft with a stroke of 72 mm (it was previously 66 mm), lightweight pistons, modified 145 mm forged connecting rods, and an old aluminum cylinder block […]

The M54B25, a highly popular 2.5-liter engine in the M54 series (which also includes the M54B22, M54B30, and S54B32), replaced the M52TUB25 on the BMW production line in 2000. The M54 and M52 differed in that the new engine’s cylinder block was still aluminum with cast-iron sleeves and a cast-iron crankshaft; connecting rods (145 mm) […]

Originally installed on the redesigned BMW E46 and E39, the BMW M54B30 engine was developed in 2000 based on the M52TUB28. The M54B22, M54B25, and S54B32 are among the new motors in addition to the M54B30. Cast iron liners are used in the aluminum alloy cylinder block, just like in the M52B28TU engine. BMW introduced […]

By adapting its geometry to the M51’s specifications, the 2.5-liter BMW M57D25 engine was developed based on the 3-liter M57D30. cylinder block made of cast iron. The M57D25 employs a twin-shaft cylinder head with four valves per cylinder, in contrast to the M51. The camshafts are rotated by the timing chain, which has a high […]

Since 1998, Munich vehicles have been equipped with M57 series motors, which have taken the place of the diesel M51. The new M57D30 engine was built using the same cast-iron cylinder block as its predecessor, but it has larger cylinders. This aluminum DOHC head has twenty-four valves. The timing chain, which has an enormous resource, […]

The M60B40 served as the model for the small V8 M60B30, which had a cylinder block with a short-stroke cast crankshaft (stroke 67.6 mm as opposed to 80 mm for the M60B40) and a cylinder diameter of 84 mm instead of 89 mm. Pistons and connecting rods were replaced, respectively. Cylinder heads from a 4-liter […]

The M60B40 engine block has a forged crankshaft, nickel-plated liners, and a 90° camber aluminum construction. Since the end of 1994, the piston has also changed, and the block has been swapped out for a more dependable aluminum one. Each aluminum cylinder has four valves, two camshafts, and hydraulic compensators. The intake and exhaust valves […]

In 1996, the M60B30 was superseded by the new junior V8 BMW M62B35 model. This engine was based on the M62B44 engine, which had its cylinder diameter reduced to 84 mm and a short-stroke crankshaft installed in its block. Only since 1998 have the sleeves changed from nikasil to alusil. The upgraded motor had new […]

A new, modified M62 series took the place of the M60 engines in 1996, while the upgraded M62B44 engine took the place of the M60B40. The 4.4-liter power unit’s predecessor, the M60B40, served as the model. Its cylinder block was modified to accommodate a larger cylinder diameter; the sleeves were originally made of nikasil, but […]

The M60 was replaced by the BMW M62 engine, which was manufactured between 2001 and 2003. When the BMW X5 E53 was first introduced in 1999, it immediately became known as a dynamic sports SUV, and the standard 4.4-liter M62B44 engine didn’t seem to have enough power. The M62B46 engine emerged as a result of […]
