Plot Twist: Mercedes-Benz Says ‘Nein’ to BMW Engine Partnership
Remember when your brain broke trying to imagine a BMW engine powering a Mercedes? Well, buckle up because that fever dream just got murdered by reality. Mercedes CTO Markus Schaefer completely shut down rumors about sourcing BMW’s 2.0-liter turbocharged engine. Honestly, we saw this coming from a long way off.
The Rumor That Had Everyone Losing Their Minds
If you want to know more about the back story, click here. Initial reports suggested Mercedes was in talks to source BMW engines starting from 2027. This sounded like automotive fan fiction written by someone who’d never met a German engineer.
The alleged deal would have involved BMW’s turbocharged 2.0-liter four-cylinder appearing in Mercedes vehicles. This would make every car enthusiast question their understanding of brand loyalty and engineering pride.
Think about it logically, though: Mercedes letting BMW engine tech power their cars sounds insane. This would be like Coca-Cola asking Pepsi to make its secret formula instead. The sheer audacity of suggesting this partnership shows how desperate some people think the industry has become.
Why This BMW Engine in a Mercedes Fantasy Never Made Sense
Mercedes has already developed its own FAME (Family of Modular Engines), which covers all displacements and meets Euro 7, China 7, and US regulations. Why would they throw away millions in research and development to buy engines from their biggest rival?
Mercedes has been building engines since before your great-grandfather was born, and suddenly they need BMW’s help? The math simply doesn’t add up when you consider the engineering pride and brand identity at stake here.
The Real Story
Speaking at the IAA Mobility Show in Munich, Schäfer flat-out dismissed the reports and confirmed Mercedes will not use BMW’s B48 engine. He literally said, “There is no truth to this,” which is corporate speak for “whoever started this rumor needs to touch grass ASAP.”

The timing of these rumors, coinciding with EV sales struggles, makes perfect sense, though. Nothing generates clicks quite like suggesting sworn enemies might become best friends. Some reports even speculated that this could help BMW secure their Steyr plant operations permanently.
What This Means For German Engineering
This whole situation perfectly illustrates why brand identity matters more than cost savings in the premium segment. Mercedes didn’t spend 138 years building their reputation just to slap BMW engines into their cars and hope nobody notices.
The rejection also proves that despite industry consolidation trends, some rivalries run deeper than quarterly profit reports. Mercedes would rather develop ten new engine families than admit BMW makes something they actually need.
Conclusion
The Mercedes-BMW engine partnership was always automotive clickbait disguised as a serious industry analysis. Mercedes just served it the corporate equivalent of a restraining order and restraint. Sometimes the most obvious answer is the right one: competitors compete, period.
