PACCAR and Toyota Motor North America announced an expansion of their joint efforts to develop and produce zero emissions, hydrogen fuel cell (FCEV) Kenworth and Peterbilt trucks powered by Toyota’s next-generation hydrogen fuel cell modules. The expanded agreement supports ongoing development and commercialized zero-emission versions of the Kenworth T680 and Peterbilt 579 models featuring Toyota’s hydrogen fuel cell powertrain kit, with initial customer deliveries planned for 2024.

PACCAR and Toyota say they have collaborated on FCEV truck development for the past several years, including a pilot program that deployed 10 Kenworth T680 FCEV trucks at the Port of Los Angeles. The companies say the pilot provided both Kenworth and Toyota with real-world feedback that further enhanced the performance and range of the vehicle.

Designed for use in heavy-duty commercial vehicles, Toyota’s heavy-duty fuel cell electric powertrain kit was recently awarded the Zero Emission Powertrain certification by the California Air Resources Board (CARB). Toyota will begin assembly of the modules in the United States in late 2023.
