Peterbilt Motors Co. announced the availability of its new Cummins X15N natural gas engine on Models 579, 567 and 520. Orders are scheduled for production in the third quarter of this year. The X15N is optimized for weight, space and durability, the company says. This makes it ideal for short-haul, long-haul, refuse and construction customers requiring a larger displacement engine, which also significantly reduces emissions, it adds. “The new X15N natural gas engine provides another environmentally friendly solution for Peterbilt customers committed to sustainability and reducing their carbon footprint,” said Jake Montero, Peterbilt assistant general manager, sales and marketing, in a statement. With ratings up to 500 horsepower and 1,850 pound-foot of torque, the X15N offers up to 10% fuel economy compared with the ISX12N. The product also offers improved low speed drivability and extended service intervals for reduced maintenance costs. Peterbilt says that the X15N is designed to meet the stringent 2024 and 2027 EPA and CARB regulations. Customers can place orders for the Cummins X15N natural gas engine option through any of Peterbilt’s more than 425 dealer locations in North America.
