Knight Transportation, the Phoenix, Arizona-based fleet, is reporting early results of its field test of Cummins’ new X15N natural gas engine, calling the early testing “successful.”
The fleet has been running a truck with this engine in Southern California. The truck is fueled exclusively with Clean Energy ultra-low carbon Renewable Natural Gas (RNG) anchored by Clean Energy’s station in Carson, California.
“The feedback in the development process is invaluable to the products long-term success for our customers. The suite of integrated Cummins technologies used on these trucks from engine, aftertreatment, and fuel storage to transmission, axles and the digital features that pull them all together in their most optimized form demonstrates the value of our next generation of product to our customers,” said José Samperio, vice president of North American on-highway business at Cummins Inc.
The field testing with Knight-Swift will continue through full production of the X15N powertrain in 2024.
