Cummins and Navistar International announced Monday another step forward in their partnership by extending their long-term agreement through the next two emission cycles, with Cummins being selected as Navistar’s preferred supplier of medium-duty and heavy-duty big bore engines for International Trucks and IC Buses in U.S. and Canada.

“We’re excited to deepen what is an already strong partnership with Navistar, spanning more than 80 years,” says Srikanth Padmanabhan, president, Engine Business, Cummins. “Navistar is a critical partner to Cummins and we believe the International LT Series trucks paired with the Cummins X15 Efficiency Series and Eaton Cummins Endurant HD transmission provides the best fuel economy, improved uptime and overall TCO for our mutual long haul customers.”

With Cummins’ successful launch of the 2021 Greenhouse Gas complaint X15 Efficiency Series engine this year, International Truck customers will receive the reliable and highly fuel efficient 15-liter product available, the companies say.

“The Cummins engine paired with Navistar International vehicles showcase technology-driven innovation that delivers the performance heavy-duty customers have come to expect to meet the demanding transportation needs of today and tomorrow,” Padmanabhan says. “Extending this relationship through a long-term partnership ensures that both companies will be able to collaborate and meet the challenges of the next emissions cycles and beyond.”

The Cummins B6.7 and L9 engines will continue to power the International MV and HV Series trucks, as well as Navistar’s IC Bus CE and RE Series school busses.

“This new long-term agreement with Cummins, in combination with our proprietary powertrains, will offer International customers the most competitive and fuel efficient engines in the market while reducing our investment requirements to meet future emissions regulations,” says Phil Christman, president, Operations, Navistar. “The extension of our partnership allows both companies to optimize future research and development investments in existing technologies as well as the flexibility to invest in advanced technologies.”
