Navistar, Inc. said Tuesday it will relaunch its heavy-duty International WorkStar vocational trucks to include company’s 13-liter engine with Selective Catalytic Reduction (SCR) emissions technology.
The WorkStar is the fourth heavy-duty International truck model to switch to SCR technology since December. The phasing-in of SCR technology is expected to conclude next month.
“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,” Bill Kozek, president of Navistar’s North America Truck and Parts, says.
The company’s portfolio of SCR-based heavy-duty trucks already 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 is made available in the WorkStar. The remaining line-up 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.
The heavy-duty WorkStar model includes two variations – 7600 SBA (46″ set-back axle) and 7600 SFA (30″ set-forward axle). Both models feature a 113″ from bumper to back-of-cab.
