Navistar announced that the first International ProStar+ Class 8 on-highway tractor equipped with the Cummins ISX15 and SCR-based Cummins Emission Solutions aftertreatment system rolled off the production line this week at the companys Escobedo, Mexico, plant.
In July, after several years of trying to meet EPA 2010 emissions standards through its In-Cylinder Technology, Navistar announced it would add Cummins' urea-based aftertreatment to its engines to meet EPA 2010 limits and position the company to meet greenhouse gas rules in advance of 2014 and 2017 requirements.
Engineering teams from both Cummins and Navistar have been working in close collaboration, fully integrated and co-located in a dedicated section of Navistars headquarters in Lisle, Ill.
These initial saleable ProStar+ with ISX15 units will be added to Navistars existing test fleet as the companys engineering team begins its final validation processes prior to the launch of customer units in December. Navistar has secured orders for more than 1,000 ProStar+ trucks with the ISX15.
The International ProStar+ with MaxxForce 13 and 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.
