Cummins to Develop Next-Generation Engine for Military Combat Vehicles

Cummins Inc. signed a $47.4 million contract to develop and demonstrate a technologically advanced engine for the next generation of U.S. combat vehicles.

The National Advanced Mobility Consortium awarded the contract for the Advanced Combat Engine to Cummins, which will be supported by San Diego-based Achates Power Inc.

Together, they plan to reduce heat rejection by 21%, compared with current Cummins-supplied combat vehicle engines, improve power density by more than 50% and reduce fuel use by 13%, compared with current typical combat vehicle engines, according to Cummins.


“We are confident we can achieve significant improvements in mobility, power, range and fuel economy, creating combat vehicles that are safer, faster and have clear advantages in the field,” said Wayne Eckerle, vice president of corporate research and technology. Cummins is based in Columbus, Ind.

The Advanced Combat Engine is a key component of the Army’s 30-year strategy to modernize tactical and combat vehicles, with potential for future production configurations being used in the Bradley Family of Vehicles and the Next Generation Combat Vehicle, according to Cummins.

“This award builds upon 14 years of extensive development by Achates Power to modernize and optimize the opposed-piston engine,” Achates Power CEO David Johnson said in a statement. “We are pleased to support Cummins on the Multi-Cylinder Advanced Combat Engine Technology Demonstrator program with our strengths in opposed-piston engine technology to deliver a superior engine for combat and tactical vehicles for the U.S. Army.”
