Navistar International Corporation announced the expansion of its medium-duty engine offerings to include the Cummins ISB 6.7-liter engine for International DuraStar medium-duty trucks. “Adding the proven, market accepted Cummins ISB to our line-up is a key part of our strategy to offer our customers the most comprehensive medium-duty truck offerings,” said Jack Allen, Navistar Chief Operating Officer. “The ISB will complement our existing engine offerings and will be a catalyst as we look to improve our medium-duty truck business in 2014 and beyond.”

International DuraStar trucks with the Cummins ISB will be Navistar’s first medium-duty vehicles with Selective Catalytic Reduction (SCR) emissions after treatment. Navistar will begin taking orders immediately for trucks with the Cummins ISB with initial truck builds later this month and regular production for trucks scheduled for December.

Industry Acceptance of Proven Engine/Chassis Combination

“Medium-duty truck customers from across the industry have extensive familiarity and confidence in the Cummins ISB. Adding it to our proven DuraStar products, along with our industry-leading dealer network, will provide customers with a winning combination,” said Bill Kozek, Navistar President, North America Truck and Parts. “Customers seeking commonality in their engine line-up have expressed significant interest in combining the Cummins ISB engine with our chassis and we anticipate straong demand and orders as a result.”

While the Cummins ISB is a new offering for Navistar’s medium-duty trucks, Navistar has gained extensive 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 customers by adding a proven mid-range SCR engine to its line-up. 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.
