Navistar Launches WorkStar With SCR

Posted on August 14, 2013

Navistar has announced the launch of its heavy-duty International  WorkStar vocational trucks powered by the company’s 13 L engine with selective catalytic reduction (SCR) technology from Cummins Emission Solutions. 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 L SCR engine, we continue to make great progress in our engine transition strategy and customers are benefitting from our expanded product line-up,” said 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 diesel engine. The 13 L engine with SCR being used in the WorkStar was launched in the ProStar in April. Navistar said 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.

The WorkStar truck is available with engine ratings from 365 hp with 1250 lb.ft. of torque to 475 hp and  1700 lb.ft. of torque and in 4x2, 6x4 and 8x6 axle configurations.
