Each BMW fanatic has an opinion on the model’s biggest engine. Some argue for the S85 and its V10 theatrics. Others swear by the bulletproof appeal of an M30, or the fashionable perfection of the B58. But when we’re speaking concerning the engine that actually formed BMW—globally and particularly right here in North America—there’s just one actual reply.
It’s the M10.
I’ve spent years driving, reviewing, researching, and writing about BMWs. I’ve talked with engineers in Munich, collectors in North America, and old-school mechanics who’ve rebuilt extra engines than most individuals will ever see. Throughout all of that have, one theme retains coming again: the M10 is the inspiration. The blueprint. The explanation the remainder of BMW’s story even exists.
This isn’t nostalgia or romanticism. It’s historical past. And it’s actuality.
The Engine That Saved BMW
The M10 arrived in 1961, at a time when BMW was barely holding itself collectively. The corporate wanted an engine that might help a number of fashions, meet new emissions and effectivity calls for, and keep dependable in international locations with dramatically totally different climates and gasoline qualities. The M10 did all of that, and it did it for practically three many years.
It powered the Neue Klasse sedans that rescued BMW from monetary collapse. It powered the 1800Ti/SA—the model’s first road-legal homologation particular. It powered the 1600 and, ultimately, the 2002, which grew to become the model’s first true gross sales success outdoors Europe. And later, in a very totally different universe, the identical engine block powered the most absurd turbocharged Method 1 energy unit ever created. No different BMW engine has a résumé even shut.
The M10 and the American Breakthrough
Ask any long-time BMW proprietor within the U.S. the place the model actually started right here, and most will level to the 2002. It wasn’t the quickest or fanciest automotive in the marketplace within the late Nineteen Sixties, but it surely drove otherwise. It felt tight. It felt awake. It felt engineered. The M10 was the explanation.
American patrons on the time have been used to large-displacement V8s and numb suspensions. The 2002 confirmed them one thing new: a small German sedan with a free-revving, keen engine that made on a regular basis driving really feel enjoyable. This wasn’t advertising and marketing; it was mechanical persona. The 2002 grew to become an icon due to the way it drove, not due to the way it was marketed.
With out the M10, that second by no means occurs. With out the 2002, BMW doesn’t set up its identification within the U.S. And with out success within the U.S., BMW doesn’t develop into the worldwide powerhouse it’s at the moment.
A Workhorse With Infinite Potential
What units the M10 other than different legendary BMW engines is how a lot BMW requested of it—and the way willingly it complied. Designed as a easy 1.5-liter four-cylinder, it grew right into a two-liter unit, tailored to carburetors, mechanical injection, early digital injection, and ultimately full turbocharging. It remained clean, predictable, and sturdy in every little thing from a Neue Klasse commuter to a 2002 Turbo. And even with all of the adjustments, its primary structure stayed the identical.
That stability is what let BMW flip the M10 into the M12/M13 Method 1 engine. The identical block that moved households round Europe through the week grew to become the bottom for a 1,300-horsepower qualifying grenade that launched BMW to the 1983 F1 World Championship. Mechanics who labored with these engines nonetheless say the true quantity was in all probability larger.
The M10’s DNA By no means Went Away
The M10’s affect didn’t finish in 1988. You continue to see it in engines that got here lengthy after: The structure that outlined the M20 straight-six owes its existence to the M10. The M50, M52, and M54—engines that constructed BMW’s popularity within the Nineties and 2000s—carry ahead refinements that began with the M10. Even the fashionable modular engine households observe the identical rules: compact design, balanced internals, and room to evolve.
The M10 wasn’t the loudest BMW engine. It wasn’t the largest. However it was essentially the most versatile and most impactful.
Why the M10 Is the Most Legendary BMW Engine
