All Gas engine e28's sold in the US came with electronic port fuel injection, oxygen sensor feedback systems, catalytic converters, air conditioning and a power sunroof. Common options include power windows, central locking, fog lights and an on board computer. Some e28's came with electrically adjustable seats, electrically adjustable sport seats and a high fidelity sound system.
The baby six motor found in the 524td and 528e models is known as the "M20". The M20 is a 12 valve SOHC inline six cylinder design. It had seven main bearings and seven cam shaft bearings, a rocker arm type valvetrain driven by a composite rubber timing belt. US market M20's came with cast aluminum acoustically tuned, common plenum intake manifolds and a single throttle body. This motor was first available in the european market for model year 1976 in a 2.0 L carbureted version. It later grew to 2.3 L in the E21 323i, then 2.5 L in the E30 325i and also 2.7 L in the 325 and 528e models. It is also very similar to the later 24 valve motors as in the E36 and E46 three series models, with the same basic block dimensions.
The big six motor found in the 533i and 535i models is known as the "M30". The M30 is also a 12 valve SOHC inline six cylinder design. It has seven main bearings, four camshaft bearings and a rocker arm type valvetrain. US M30's also came equipped with cast aluminum acoustically tuned common plenum intake manifolds and single throttle bodies. Unlike the M20 it has a chain driven valvetrain. Its larger dimensions allow for a longer stroke and larger bore, which makes for almost 3.5 L displacement in later motors.
The M5 came with a big six motor known as the "S38". This motor is similar to the M30, but has a 24 valve cylinder head, duplex timing chain, dual overhead cam layout and shim and bucket style valvetrain. In addition to the top end revisions, the S38 also had six individual throttle bodies and intake trumpets fed by a cast aluminum intake plenum. This motor was designed for high power and durability at very high engine speeds. In the E28 chassis it was one of the fastest sedans in the world for its time, and it remains legendary among enthusiasts today.[citation needed][1]
