Navistar International and Cummins have reached definitive, long-term supply agreements for heavy-duty diesel engines and emissions aftertreatment technologies. 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.
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 (NCPs).
