Recent rumors about Mercedes-Benz adopting BMW engines in future models have now been officially dismissed. Markus Schaefer, Chief Technology Officer at Mercedes-Benz Group, confirmed during the IAA Mobility Show in Munich that the company has no plans to rely on external powertrains, especially from a rival like BMW.
Speculation had circulated that Mercedes might use BMW’s 2.0-liter turbocharged B48 engine in compact vehicles and plug-in hybrid versions of the C-Class and E-Class to reduce development costs and comply with Euro 7 regulations. However, Schaefer firmly rejected these claims, emphasizing that Mercedes has already developed its own advanced engine family, known as FAME (Family of Modular Engines). This platform, introduced four years ago, includes four-, six-, eight-, and twelve-cylinder engines designed to meet EU7, China 7, and U.S. emissions standards.
Schaefer further highlighted that Mercedes is completing development on a new high-performance V-8 engine fully compliant with strict regulations, while V-12 engines will continue to remain part of the lineup. He stressed that the brand’s combustion engines are fully modernized and prepared for the future, with no outsourcing needed.
The official denial arrives at a critical moment, as Mercedes balances electrification with a continued commitment to internal combustion. For instance, the upcoming GLC will offer both electric and combustion-powered versions at similar price points, signaling a major shift in the company’s strategy. With this announcement, Mercedes reinforces that its engine identity will remain entirely “Made in Stuttgart.”
