Cummins will launch the diesel X15 engine for the heavy-duty on-highway market. As the next product in the Cummins HELM 15-liter fuel agnostic platform, the diesel X15 will be compliant with U.S. EPA and CARB 2027 aligned regulations at launch.
“We have applied our decades of experience with the X15 to our next-generation product and believe these investments will serve our customers well into the future. The next generation X15 is the next evolution of technology, truly proving to the world that we never stop innovating,” said José Samperio, vice president, North America On-Highway at Cummins. “We are working hard to ensure the new product delivers our brand promise to customers for the important jobs they need to do every day.”
Maintaining the reliability that has met the needs of a diverse customer base since the inaugural X15 launch in 1998, the next generation diesel X15 will retain the same ratings of the current X15 (up to 605 hp and 2,050 ft.-lb. of torque) and optimize powertrain integration with Eaton Cummins and Cummins-Meritor.
“Today, we re-introduce our fuel agnostic engine platforms with a name that captures the innovation that powers us forward: the Cummins HELM platforms,” said Jane Beaman, vice president Global, On-Highway Business, Cummins.
“With higher efficiency, lower emissions, and multiple fuels, the Cummins HELM platforms give our customers control of how they navigate their own journeys as part of the energy transition. They can choose the fuel types that work best for them, their businesses, and their goals.”
This next-generation engine is designed to have the capability to meet future emissions regulations beyond 2027 without the need for significant architecture changes.

“This new architecture expands on the legacy of the X15 engine. All teams involved recognize how important this product is and what it means for both Cummins and our customers’ future as the base architecture will carry us through the horizon of diesel technology and alternate fuels,” said Jonathon White, vice president, Engine Business Engineering, Cummins.
From its inception, the next generation X15 was developed with Cummins’ fully integrated powertrain in mind. The X15 architecture utilizes a belt-driven, high output 48-volt alternator and aftertreatment heater solution.
Customers utilizing EX ratings (requires Eaton Cummins Endurant and GPS look-ahead data) with Cummins Meritor axles, brakes and drivelines will experience additional drivability through features such as predictive gear shifting, on-ramp boost and hill roll out.
