The S54 with the internal engine designation S54B32 is an engine from BMW M GmbH and was introduced in 2000 in the M3 of the E46 series. The engine is not based on the M54 engine of the BMW AG vehicles, but was developed from its predecessor, the BMW S50B32 , mainly installed in the BMW M3 of the E36 series . The S54 is a 3246 cm³ high-speed in- line six-cylinder petrol engine. The engine has a camshaft adjustment for inlet and outlet ( stepless high-pressure double VANOS ). He weighs 212 kg.

development

According to many, the BMW S50B32 sports engine installed in the BMW M3 E36 had reached the maximum output level. The main reason for this was the constructive effort involved and the cylinder spacing, which was already almost exhausted. This stood in the way of a further increase in displacement and thus an increase in performance. As part of the extensive revision, the design features of the S50 were adopted (gray cast iron block, single throttle, double VANOS, manifold, etc.), but almost every detail was revised to a large extent. There was still a slight increase in displacement against the S50B32 from 3.201 cm 3 to 3,246 cm 3 and an increase of the rated speed of 7,400 min -1 min to 7,900 -1 achieved. Thus, the output compared to the S50B32 by almost 7% from 236 to 252 kW, the torque of 350 Nm at 3250 min -1 to 365 Nm at 4900 min -1 (see also data web link auto motor and sport.de).

In the BMW E90 M3 , the successor to the BMW S65 , a high-revving 4-liter V8 engine, was used.

There is also a P54 version with 2 l displacement from 2003 (see picture). The cylinder head and the one-piece cylinder block are made of aluminum, with the block having inserted gray cast iron liners. The engine weighs 137 kg. The pistons are forged box-type pistons and the connecting rods are high-strength steel connecting rods. Six high-performance pencil-type ignition coils with integrated ignition drivers are used for ignition. The BMW Motorsport 12A-R6 engine control unit uses three powerful microprocessors; the injection takes place cylinder-selectively.

S54B32

S54B32 E36 / 7

  • BMW Z3 M Roadster E36 / 7 and M Coupé E36 / 8 (04 / 2001-07 / 2002) (lower output due to different exhaust system)

S54B32HP

S54B32US

  • BMW M3 E46 US version (2000–2006) (reduced performance, since the exhaust gas catalytic converters are arranged in the manifold due to stricter US emissions regulations)
