‘Fabulous’ year for Cummins X15N natural gas engine
From tough terrain across the United States for UPS to steep grades in Canada, Cummins’ X15N natural gas engine has spent its first year proving it can handle heavy hauls while delivering near-zero emissions at a lower fuel cost than diesel.
It’s been a year since Cummins launched its X15N natural gas engine and its résumé keeps growing. With up to 500 horsepower and 1,850 lb.-ft. of torque, the X15N is the trucking industry’s most powerful natural gas engine yet. It continues opening doors to heavy hauls that were previously closed to natural gas.
Released ahead of 2027 emission standards adopted by the Environmental Protection Agency and the California Air Resources Board, the X15N has been meeting those strict regulations while delivering what customers describe as diesel-like performance.
The green profile gets even better for fleets and owner-operators using renewable natural gas (RNG), which has the lowest carbon intensity score of all transportation fuels.
Growing RNG availability has made the X15N an even stronger option for fleets.
“It’s been fabulous,” Cummins Product Manager of Natural & Renewable Gas Engines David King said recently in a Cummins Power Onward podcast. “We’ve had people refer to it as a gamechanger for the industry. There’s been a lot of excitement. A lot of customers who were natural gas customers with us are adopting but also customers who have never used natural gas are trying it out and moving some of their fleet over.”
