Navistar Rolls Out Heavy-Duty Truck with SCR Emissions Tech

Navistar Inc. has debuted the International WorkStar heavy-duty vocational trucks featuring the company's 13-liter engine with selective catalytic reduction (SCR) emissions technology.

‘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 lineup,’ says Bill Kozek, president, North America Truck and Parts, for 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 WorkStar is the fourth heavy-duty International truck model to transition to SCR technology since December 2012. 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 of which are available with the Cummins ISX15 engine. Navistar's 13-liter engine with SCR was launched in the ProStar in April.

The WorkStar is available in configurations from 365 hp/1,250 lb-ft torque up to 475 hp/1,700 lb-ft torque.
