International Truck begins production of International WorkStar with Cummins ISB6.7 engine

International Truck announces that it has started production of its first International WorkStar vocational trucks powered by the Cummins ISB6.7 engine. Both the WorkStar and the International DuraStar medium-duty truck are available with the ISB6.7 as an engine option.

"Production of the WorkStar with Cummins ISB6.7 is an important milestone in meeting the needs of vocational customers by providing a comprehensive offering of proven components," says Jeff Sass, Navistar Senior Vice President, North America Truck Sales and Marketing. "The WorkStar with Cummins ISB6.7 gives customers a winning combination of performance and strength."

The WorkStar boasts multiple-frame rail options, a double-sided galvanized steel cab protected by an extensive five-step corrosion protection process, and comes standard with the Diamond Logic electrical system—the most advanced multiplexing architecture available in commercial trucks.

The addition of the Cummins ISB 6.7-liter engine expands the WorkStar model's extensive powertrain options, which include Navistar's proprietary 9.3- and 13-liter offerings.

WorkStar is also available with a suite of traditional manual and automated-manual transmission offerings from Eaton and fully-automatic offerings from Allison. The Cummins ISB6.7, rated up to 325 hp and 750 lbs.-ft. torque, features flexible horsepower and torque ratings, with higher ratings specifically for fire and emergency applications.

"The International WorkStar with Cummins ISB6.7 is the right truck for a large portion of our vocational customers," says David Hillman, Vice President and General Manager, International Truck Vocational Product Line. "Customers don't have to compromise. They can have it all—efficiency, comfort, capability and now the proven Cummins ISB6.7 engine."
