There is therefore no direct successor to the S38, however the BMW S50 engine took over as BMW's high performance straight-6 engine. The S38 is based on the M88/3 engine. Compared to the M88/3, the S38 has a lower compression ratio (9.8:1), simplified exhaust manifold, catalytic converter , dual-row timing chain and
