Together with Arizona-based company Knight Transportation, Cummins managed to test the new X15N natural gas engine in Southern California. The latter will be launched in 2024. Due to the participation of another partner within the project, the truck was fueled exclusively with Clean Energy ultra-low carbon Renewable Natural Gas (RNG) anchored by Clean Energy’s station in Carson, California.
The Cummins X15N natural gas engine delivers diesel-like ratings as well as durability and reliability to allow fleets to significantly reduce their carbon footprint without sacrificing capability. The X15N offers the industry a solution toward achieving their sustainability goals, including the ability to run on renewable natural gas. The field testing with Knight-Swift will continue through full production of the X15N powertrain in 2024.
