Navistar International Corporation has announced the expansion of 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.
“The ISB will complement our existing engine offerings and will be a catalyst as we look to improve our medium-duty truck and bus business in 2014 and beyond,” said Jack Allen, Navistar executive vice president and chief operating officer.
“Customers seeking commonality in their engine line-up have expressed significant interest in combining the Cummins ISB engine with our chassis and we anticipate strong demand and orders as a result," added Bill Kozek, Navistar president, North America Truck and Parts.
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 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.
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.
