Cummins, Daimler truck sign medium-duty engine pact

Under a strategic partnership announced this year between Cummins and Daimler Truck AG, Cummins will invest in the further development of the medium-duty engine platform and its global production and delivery starting in the second half of the decade for Daimler Trucks & Buses.

As a result, Daimler Truck AG will no longer invest its own funds in the further development of its medium-duty engines for the Euro VII 2025 emissions standard, which is expected to be Europe's final step in tightening emissions regulations as the continent works toward phasing out fossil fuels entirely.

Stateside, the implications will be that the same platform will eventually replace the Detroit DD8 and DD5 engines as available power plants in North American trucks. Current Greenhouse Gas Phase II regulations governing heavy truck emissions in the U.S. are already in place through model year 2027.

The Daimler heavy-duty engine platform (HDEP) for the heavy-duty vehicle segment of Daimler Trucks and Buses will remain in the Daimler Truck AG portfolio. The HDEP engine family will continue to be manufactured by the global production network in Mannheim and Detroit, Michigan, and fitted in heavy-duty trucks, in touring coaches as well as in third-party products worldwide.
