Navistar International Corp. today (Oct. 22) announced it has reached definitive, long-term supply agreements for heavy-duty diesel engines and emissions aftertreatment technologies with Cummins Inc.
According to a news release, Navistar will offer the Cummins ISX15 in its International ProStar, PayStar and 9900 models. In addition, Navistar will utilize the proven Cummins Emission Solutions aftertreatment system for the company’s proprietary heavy-duty big bore engines.
“This agreement represents a natural extension of the long-standing relationship between Navistar and Cummins and our history of collaboration in serving our mutual customers,” said Troy Clarke, Navistar president and COO. “With the addition of the Cummins ISX15 and the use of the proven Cummins aftertreatment system, we are on a clear path to providing customers with proven, reliable and fuel-efficient clean engine technology.”
Engineering teams from both Cummins and Navistar have been working in close collaboration over the past several months to integrate vehicle, engine, and emissions aftertreatment systems. With a formal, finalized agreement, the teams are now focused on a swift, well-executed and high-quality launch.
Navistar will begin its initial pilot builds of the International ProStar+ with the Cummins ISX15 in November 2012 with first customer shipments in December 2012. The International ProStar+ with MaxxForce 13 and the Cummins Emission Solutions SCR-based aftertreatment system will enter initial pilot production in March 2013 with regular production to begin in April 2013.
The remaining line-up of heavy-duty truck models will transition to SCR-based clean engine technology in a phased launch throughout 2013 based on volume and customer demand.
During the transition, Navistar will continue to build and ship EPA-compliant trucks in all vehicle classes using appropriate combinations of earned emissions credits and/or non-conformance penalties.
