Freightliner has announced it is offering the Cummins X15N natural gas engine in its Cascadia heavy-duty trucks.

“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, on-highway market development, Daimler Truck North America.

“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.”

The engine can be spec’d in Cascadias with a 126-inch BBC in sleeper and day cab configurations, with production to begin in 2025.

“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 NOx,” said José Samperio, Cummins vice-president and general manager, North America on-highway.

“The X15N, an industry first big bore natural gas powertrain with power and torque curves almost identical to diesel will help long-haul fleets see improved economic and environmental performance.”

Cummins notes the X15N’s emissions can range from carbon-negative to a 90% reduction in CO2 emissions, depending on the source of the natural gas.
