Clean Energy Fuels launches new demo truck program
The initiative showcases the 2026 Freightliner Cascadia Gen 5 equipped with Cummins’ natural gas engine, advancing low-carbon trucking in North America.
Clean Energy Fuels announced the launch of its second heavy-duty demo truck program, featuring the 2026 Freightliner Cascadia Gen 5 day cab powered by the Cummins X15N natural gas engine. The new truck will debut at the American Trucking Associations’ Management Conference & Exhibition (ATA MCE), held October 25–28 in San Diego, before entering real-world operation with its first fleet partner.
Building on the success of Clean Energy’s earlier Peterbilt X15N demo, the new program offers fleets a hands-on opportunity to test the next generation of low-emission, high-performance trucks. The program will give carriers nationwide the chance to experience the truck’s performance while refueling at the company’s extensive RNG station network
“The Cummins X15N is a game-changer,” said Chad Lindholm, Senior Vice President at Clean Energy. “Providing equivalent power and torque as its diesel equivalent, yet allowing fleets to claim significant carbon and NOx emission reductions with a fuel that is priced at a big discount to diesel.”
After its launch, the demo truck will tour major freight corridors across the U.S., including California, Texas, Arizona, Illinois, Ohio, Michigan, Pennsylvania, and Florida. This tour is part of a multi-year initiative running through 2028 and beyond to help accelerate the adoption of cleaner heavy-duty transport solutions.
