Werner Enterprises and Cummins Inc. have announced that Werner will begin validation and integration of Cummins' recently announced 15-liter natural gas and 15-liter hydrogen internal combustion engines in its vehicles. Cummins will begin integrating these new powertrains in Werner trucks in the second half of 2022, starting with the 15-liter natural gas product. The 15-liter natural gas engine announced in October of 2021 can be paired with a Cummins Eaton Automated Transmission Technologies Endurant HD Transmission and Cummins Fuel Delivery System, ensuring a purpose-built and fully integrated natural gas powertrain.

Other transmission pairings will be available at launch for specialized applications. The 15-liter engine will offer ratings up to 500 horsepower and 1,850 ft-lbs of torque, while not requiring selective catalytic reduction (SCR) to meet 2024 California or Environmental Protection Agency emission standards, providing a potentially carbon-negative solution when powered with renewable natural gas (RNG).
