DENTON, Texas  – Peterbilt announced today that it will be working with Cummins to develop technologies under the US Department of Energy (DOE) SuperTruck II program.

“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,” added Wayne Eckerle, Cummins vice-president of research and technology.

Peterbilt says it will be working to improve aerodynamics by 15% in all wind directions, which will provide customers an up to 7.5% improvement in fuel economy.

“Peterbilt recognizes customers’ needs for reduced fuel costs,” said Scott Newhouse, Peterbilt chief engineer. “Our aerodynamic and fuel saving initiatives align with the goals of the SuperTruck II program.”

The SuperTruck II program is a five-year program between Peterbilt and Cummins. They worked together before 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.
