Navistar’s First International ProStar+ With Cummins ISX15 (SCR) Rolls Off Production Line
First SCR-Based Clean Engine Technology Milestone Reached as Company Prepares for Customer Deliveries in December, Full Production in January


ESCOBEDO, NUEVO LEON, MEXICO — November 15, 2012— Navistar International Corporation (NYSE: NAV) announced today 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. Together, the teams have been laser-focused on a flawless execution of the launch plan, with a high attention to detail while defining and upholding stringent quality metrics.

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 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 (NCPs).
