Navistar Inc. announces the launch of its heavy-duty International WorkStar vocational trucks powered by the company's 13-liter engine with Selective Catalytic Reduction (SCR) emissions technology. The WorkStar is the fourth heavy-duty International truck model to transition to SCR technology since December 2012.

"With the launch of the WorkStar with our 13-liter SCR engine, we continue to make great progress in our engine transition strategy and customers are benefitting from our expanded product line-up," says Bill Kozek, President North America Truck and Parts, Navistar. "We're well positioned to continue our positive momentum and we are on schedule to complete the SCR transition in our remaining heavy-duty truck offerings by early August."

The company's portfolio of SCR-based heavy-duty trucks also includes the International ProStar, International PayStar 5900 Set-Back Axle and International 9900i—all available with the Cummins ISX15 engine. In addition, Navistar's proprietary 13-liter engine with SCR was launched in the ProStar in April and is now available in the WorkStar. The remaining lineup of International heavy-duty truck models will transition to SCR emissions technology in a phased launch in the coming weeks based on volume and customer demand.
