The BMW E28 535i, manufactured from 1984 to 1987, boasts the M30B34 engine—a 3.5-liter inline 6-cylinder petrol engine that is part of the revered M30 family. This engine series is celebrated for its durability and smooth operation, attributes that have cemented its place in BMW’s engineering history.
Designed with a cast iron block and an aluminum head, the M30B34 features a single overhead camshaft (SOHC) and two valves per cylinder, a setup that prioritizes reliability and efficient power delivery. As a naturally-aspirated engine, it eschews the complexities of forced induction, favoring a purer driving experience that highlights mechanical simplicity and direct throttle response.
Historically, the M30 engine family has been pivotal in establishing BMW’s identity as a maker of sporty sedans that do not compromise on reliability. It is particularly well-regarded for its balanced performance, offering substantial power without the trade-offs in longevity that often come with more aggressively tuned engines.
