Navistar Adding Cummins ISB SCR Diesels

Posted on September 3, 2013

Saying that it did not foretell a departure from manufacturing their own engines, Navistar International Corp. said it has expanded its medium-duty engine offerings to include the Cummins ISB 6.7-liter engine for International DuraStar medium-duty trucks and IC Bus CE Series school buses.

International DuraStar trucks and IC Bus CE Series school buses with the Cummins ISB will be Navistar's first medium-duty vehicles with selective catalytic reduction (SCR) emissions aftertreatment. Navistar said it will begin taking orders immediately for trucks and buses with the Cummins ISB with initial truck builds later this month and regular production for trucks scheduled for December. Regular production for CE Series school buses is scheduled for late-January 2014.

When asked if this announcement might add to the perception that Navistar might eventually exit the engine business, Bill Kozek, Navistar president North America Truck & Parts said, "we are not exiting the engine business."

While the Cummins ISB is a new offering for Navistar's medium-duty trucks and buses, Navistar said it has gained experience packaging and manufacturing medium-duty trucks with the Cummins ISB since 2010 through its Ford Blue Diamond joint venture.

The Cummins ISB allows Navistar to meet the needs of its truck and bus customers by adding a proven mid-range SCR engine to its line-up, the company said.  The company will announce the next steps of its comprehensive mid-range SCR engine strategy at a later date. In the meantime, Navistar will continue to offer EGR-only versions of its mid-range engines utilizing its medium-duty emissions credits, saying those credits could extend through at least “next year.”
