Navistar Inc. has launched its International TranStar regional haul tractor with MaxxForce 13 engine with Selective Catalytic Reduction (SCR) emissions technology.

The TranStar is the fifth heavy-duty International truck model to transition to SCR technology since December 2012. 

“We continue to rapidly increase our 15-liter and 13-liter product coverage and we remain on track to complete the SCR transition of our heavy-duty truck offerings,” said Bill Kozek, president North America Truck and Parts, Navistar. “The trucks we are building today are the highest quality trucks Navistar has ever built and they offer improved fuel economy with the same off-the-line responsiveness.”

Today, the company’s portfolio of SCR-based heavy-duty trucks includes the International ProStar, International PayStar 5900 Set-Back Axle and International 9900i with the Cummins ISX15 engine. In addition, the International ProStar, International WorkStar and the International TranStar are available with the MaxxForce 13 engine with SCR.
