Navistar and Cummins finalize supply agreements

23 October 2012

Navistar announced that it has reached definitive, long-term supply agreements for heavy-duty diesel engines and emission aftertreatment technologies with Cummins. Through these agreements, Navistar will offer the Cummins ISX15 in its International® ProStar®+, PayStar® and 9900 models. In addition, Navistar will utilize a urea-SCR based aftertreatment system supplied by Cummins Emission Solutions for their heavy-duty big bore engines.

Navistar announced earlier that it will discontinue its MaxxForce 15, non-SCR diesel engine once it runs out of NOx emission credits, while the remaining heavy-duty engine models will transition to SCR-based emission technology.

Engineering teams from both companies have been working in close collaboration over the past several months to integrate vehicle, engine, and emissions aftertreatment systems, said Navistar. With a formal, finalized agreement, the teams are now focused on a swift, well-executed 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 with the Cummins 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 emission 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 a combination of earned emissions credits and/or non-conformance penalties (NCPs), said the company.
