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 company’s Escobedo, Mexico plant.
“This is a great accomplishment for Navistar and an important milestone as we bring our first SCR-based Class 8 trucks to the marketplace,” said Troy Clarke, Navistar president and COO. “The entire launch team and hundreds of others working behind the scenes are committed to a high-quality launch and this achievement is another proof point in our progress.”
Engineering teams from both Cummins and Navistar have been working in close collaboration, fully integrated and co-located in a dedicated section of Navistar’s headquarters in Lisle, Ill.
These initial saleable ProStar+ with ISX15 units will be added to Navistar’s existing test fleet as the company’s engineering team begins its final validation processes prior to the launch of customer units in December. Navistar says it has secured orders for more than 1,000 ProStar+ trucks with the ISX15.
