Navistar International Corp. said Monday it has reached long-term supply agreements with Cummins Inc. for heavy-duty diesel engines and emissions aftertreatment technologies.
Through the agreements, Navistar will offer Cummins’ ISX15 engine in its International ProStar+, PayStar and 9900 models.
Navistar said it will also use Cummins Emission Solutions’ aftertreatment system for its proprietary heavy-duty big bore engines.
“This agreement represents a natural extension of the long-standing relationship between Navistar and Cummins and our history of collaboration in serving our mutual customers,” said Troy Clarke, Navistar’s president and chief operating officer.
Engineering teams from both companies have been working closely in the past several months to integrate vehicle, engine, and emissions aftertreatment systems, and with a formal, finalized agreement, the two are “focused on a swift, well-executed and high-quality launch,” Navistar said in a statement.
Navistar said in early August it would add Cummins engines to some of its truck models after earlier announcing it would adopt selective catalytic reduction technology to meet federal emissions standards, after earlier following a different technology path.
The company will begin its initial pilot builds of the International ProStar+ with the Cummins ISX15 in November, with first customer shipments in December.
The International ProStar+ with MaxxForce 13 and the Cummins Emission Solutions SCR-based aftertreatment system will enter initial pilot production in March, with regular production to begin in April.
The remaining lineup of heavy-duty truck models will transition to SCR-based technology throughout 2013, based on volume and customer demand, Navistar said.
