Kenworth delivers 15-liter natural gas-powered truck to UPS

Kenworth delivers 15-liter natural gas-powered truck to UPS

The truck is equipped with the Cummins X15N, which Kenworth says will meet CARB and EPA Requirements for both 2024 and 2027.

In a ceremony at Kenworth’s Chillicothe, OH plant, Kenworth delivered the first T680 daycab with a 15-liter natural gas engine to UPS in late February. The Cummins X15N-equipped Kenworth T680 runs on Compressed Natural Gas (CNG) and is the first of several trucks utilizing the new powerplant that Kenworth says it is delivering to UPS. According to Cummins, the engine produces between 400-500 hp with up to 1,850 lb.-ft. of torque. 

The first UPS truck has the engine rated at 400 HP with 1,650 lb.-ft. of torque, according to Kenworth, and it came paired with an Eaton Endurant HD Automated Transmission and a 175-diesel gallon equivalent (DGE) fuel delivery system.


Kenworth says that the Cummins X15N will meet upcoming 2027 EPA emission requirements and CARB 2024 Low NOx standards, with CO2 and NOx levels are both 90% below current EPA standards, along with a fuel economy improvement of up to 10% over Cummins’ 12-liter natural gas engine.

“We’re thrilled to be the first company to acquire the T680 with the X15N 15-liter natural gas engine,” said Anthony Marshall, UPS’s vice president of maintenance and engineering. “This new truck enhances our worldwide fleet of over 18,000 alternative fuel and advanced technology vehicles, which are essential for achieving our target of 40% alternative fuel in our ground operations by 2025 and carbon neutrality by 2050.”
