Peterbilt, Cummins to work on SuperTruck II program

Peterbilt and Cummins will be embarking on a five-year program to develop technologies under the U.S. Department of Energy (DOE) SuperTruck II program. The technologies will double freight efficiency to achieve Greenhouse Gas Emissions (GHG) requirements set forth for model years 2021, 2024 and 2027.

“Peterbilt is proud to support the DOE’s SuperTruck II program in cooperation with Cummins,” said Darrin Siver, Peterbilt general manager and PACCAR vice president. “We will work together to build on the success of our original SuperTruck program.”

“Cummins and the entire team is focused on developing technologies that can transform the industry and help our customers be more successful while continuing to be great stewards of the environment. Combining some of the best technical minds available for this project, I am confident that we can reach our goals and deliver results that are a win for our customers, a win for our organizations and a win for the environment,” said Wayne Eckerle, Cummins’ vice president of research and technology.

Peterbilt will work to improve aerodynamics by 15% in all wind directions, which will provide customers an up to 7.5% improvement in fuel economy. This enhancement will decrease aerodynamic drag and rolling resistance.

Peterbilt will work to improve fuel economy and efficiency through technologies including auxiliary systems such as air compressors, power steering pumps and cooling pumps. To reduce rolling resistance, Peterbilt will team with tire manufacturing partners to investigate alternative compounds and tire configurations for optimized surface contact.

On the original SuperTruck program, the Peterbilt and Cummins team demonstrated a 66% fuel economy improvement and 76% freight efficiency improvement over the baseline truck. Advanced aerodynamics, predictive cruise control, chassis light-weighting and battery-based A/C systems for idle reduction led to these improvements. These options are now available on Peterbilt’s Model 579 EPIQ.

After holding steady on the forecast since last July, ACT Research has pushed 2024 Class 8 production and sales expectations up in February, as published in the latest release of ACT's North American Commercial Vehicle Outlook.

“In addition to an improving economic outlook, the decision to boost the forecast, despite near-term inventory risks, reflects the industry’s ability to more aggressively sell into Mexico and export markets, while maintaining strength in domestic vocational,” said Kenny Vieth, ACT’s president and senior analyst. “The 2024 market is atypically bifurcated: considerable strength remaining in U.S. and Canadian vocational markets and Mexico helps offset otherwise weak demand in U.S. and Canadian tractor markets, LTL excluded.”
