Freightliner Offers Cummins X15 Natural Gas Engine

Freightliner, a Daimler Truck North America subsidiary, has announced that it will offer the new Cummins X15N natural gas engine in its heavy-duty Freightliner Cascadia trucks. This engine, designed for heavy-duty and on-highway truck applications, provides 400-500 horsepower and 1,450 to 1,850 pound-feet of torque. It will be available for sleeper and day cab configurations of the Cascadia 126″ BBC, with production targeted to begin in 2025. The engine is expected to significantly reduce life cycle greenhouse gas emissions when operating on renewable natural gas, ranging from a 90% reduction to a negative carbon footprint. Freightliner highlighted that the X15N achieved lower nitrogen oxide levels than the 2024 Environmental Protection Agency and California Air Resources Board standards.

‘”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.”‘
