Daimler Truck North America subsidiary Freightliner announced Oct. 5 it will offer the new Cummins X15N natural gas engine in its heavy-duty Freightliner Cascadia trucks.
Cummins is providing the engine as part of a collaboration with the truck maker.
The X15N is designed for heavy-duty and on-highway truck applications. It has 400-500 horsepower and 1,450 to 1,850 pound-feet of torque.
The engine will be offered for the Cascadia 126” BBC for both sleeper and day cab configurations. Production is targeted to begin in 2025.
“We have a number of customers that continue to run natural gas trucks today, and our goal is to provide those customers with the products, like the X15N, they need to operate successfully for their business,” said Greg Treinen, vice president of on-highway market development at DTNA. “The new X15N natural gas engine option for our Freightliner Cascadias complements our portfolio of solutions that help our customers run their fleets efficiently and sustainably.”

Freightliner noted in the announcement that the engine can significantly reduce life cycle greenhouse gas emissions of heavy-duty trucks when operating on renewable natural gas. This can range from a 90% reduction to even a negative carbon footprint, according to the company.
“Our end-user customers are looking for ways to achieve their sustainability goals, and the X15N is essential to our commitment to help customers reach net-zero greenhouse gas emissions and improve [nitrogen oxides],” said José Samperio, vice president and general manager for North America on-highway operations at Cummins. “The X15N, an industry first big bore natural gas powertrain with power and torque curves almost identical to diesel, will help longhaul fleets see improved economic and environmental performance.”
Freightliner also said that the engine achieved lower nitrogen oxide levels than the 2024 Environmental Protection Agency and California Air Resources Board standards.
