BMW’s Secret Weapon in the EV Era Is Still an Engine Plant in England

In an industry racing headlong toward batteries, silicon, and kilowatts, BMW is quietly doing something radical: perfecting the internal-combustion engine.

While headlines fixate on EV sales charts, BMW Group’s Hams Hall engine plant near Birmingham has just crossed a milestone that matters far more to driving enthusiasts—25 years of building engines that still make cars feel alive. Since 2001, more than 7.6 million engines have left this unassuming factory, powering everything from humble MINIs to the kind of Rolls-Royces that glide rather than drive.

And no, these aren’t museum pieces. They’re modern, turbocharged, emissions-scrubbed, hybrid-ready combustion engines that prove ICE tech still has meaningful evolution left in it.

The Beating Heart of BMW’s “Technology-Open” Strategy

BMW likes to talk about being “technology-open,” which in plain English means:
We’ll build EVs—but we’re not throwing away engines that still outperform them in the real world.

Hams Hall is the backbone of that strategy.

This single UK plant builds:

  • Three- and four-cylinder turbo petrol engines for BMW and MINI
  • V8s for BMW’s high-performance lineup
  • And the last production V12 on Earth, built exclusively for Rolls-Royce Motor Cars

Yes—the V12 still lives, and it’s hand-assembled by specialist technicians before being shipped to Goodwood, where Rolls-Royce installs it into cars that cost more than a house. That alone makes Hams Hall a kind of mechanical sanctuary in a disposable digital age.

Old-School Power, New-School Intelligence

What makes Hams Hall special isn’t nostalgia—it’s how modern it is.

BMW has transformed the entire factory into a fully connected digital twin. Every machine, robot, and production cell is mirrored in software. Every vibration, temperature spike, and torque setting is logged in real time. Engineers don’t guess—they simulate, predict, and optimize before problems ever occur.

And then there’s SpOTTO.

Yes, that’s a robot dog.

Developed by Boston Dynamics (as “Spot”), SpOTTO patrols the plant using cameras, microphones, and thermal sensors, scanning machines for faults, leaks, and wear. It feeds all that data into BMW’s digital systems, turning Hams Hall into something closer to a living organism than a factory.

The name isn’t random either. SpOTTO honors Gustav Otto—the man whose father invented the four-stroke engine. That’s about as poetic as industrial automation gets.

A Factory That Got Greener Without Getting Slower

Here’s the part no one expects from an engine plant: it’s one of BMW’s cleanest.

Since full production began, Hams Hall has reduced its energy use per engine by 61%. Despite building far more engines today than it did 20 years ago, the site uses roughly the same total energy. All externally sourced electricity now comes from renewables, and natural-gas consumption has been steadily cut.

In other words, BMW didn’t wait for EVs to go green—it cleaned up combustion itself.

That matters, because for the next decade at least, most BMWs will still be powered by engines. Making those engines cleaner and more efficient is just as important as selling EVs.

From i8 Three-Cylinders to Twin-Turbo V12s

Hams Hall’s résumé reads like a BMW highlight reel:

  • In 2001, it launched series production using Valvetronic, BMW’s throttle-less variable-lift valve system
  • In 2006, it began building engines for MINI
  • In 2013, it became the exclusive producer of the three-cylinder engine for the BMW i8, one of the most technically advanced sports cars of its era
  • In 2022, it took over V8 and V12 production, cementing its status as BMW’s combustion crown jewel

Few factories on Earth can go from eco-hybrid triple-cylinders to twelve-cylinder luxury engines under the same roof. Hams Hall does it daily.

Why This Matters in 2026

BMW could have walked away from combustion. Many brands are trying to.

Instead, it doubled down.

By investing in places like Hams Hall—alongside massive EV facilities in Austria, Germany, and China—BMW has positioned itself to win no matter which way the market swings. If EV adoption stalls? BMW has world-class engines. If hybrids dominate? Hams Hall supplies them. If luxury buyers demand V12s? BMW still builds them.

That’s not hedging. That’s engineering confidence.

And as long as places like Hams Hall exist, the idea that the internal-combustion engine is “obsolete” remains what it’s always been:

A misunderstanding of just how good these machines have become.
