Navistar International Corporation is expanding 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 engine will be available for order immediately.
"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 and bus offerings," says Jack Allen, Navistar executive vice-president and 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 and bus business in 2014 and beyond."
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.
While the Cummins ISB is a new offering for Navistar's medium-duty trucks and buses, 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 and bus 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.
Navistar and Cummins teams worked side-by-side over the past year to launch the Cummins ISX 15-liter engine in the company's Class 8 trucks--including the International ProStar, PayStar 5900 and 9900i models. In addition, the teams continued their close collaboration this past spring and summer as Navistar added the Cummins SCR aftertreatment system to its proprietary MaxxForce 13-liter for the successful launch of ProStar, WorkStar, TranStar and PayStar models. That same level of teamwork will continue as Navistar leverages the experience and learnings gained during its heavy-duty SCR launch for its medium-duty launch with the Cummins ISB.
