Navistar, Inc. announced the launch of its heavy-duty International WorkStar vocational trucks powered by the company's 13.0L 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, according to the company.

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 13.0L 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, according to the company.
