Navistar marks completion of heavy duty product transition to SCR

Navistar, Inc. today announced its International LoneStar on-highway tractor with Cummins ISX15 engine with Selective Catalytic Reduction (SCR) emissions technology is now available for order. The LoneStar is the company's final heavy-duty Class 8 on-highway truck model to incorporate SCR emissions technology since Navistar began its SCR transition in December 2012. 

"We now offer a full lineup of SCR product offerings for our Class 8 customers and we have completed each launch on time—and with the highest levels of quality," said Bill Kozek, president North America Truck and Parts, Navistar. "Throughout this transition, we have seen an improvement in customer confidence reflected in our Class 8 order share and we are already starting off strong with our medium-duty transition as we move into 2014."  

Navistar began its Class 8 SCR transition in December of 2012 with the on-time launch of the International ProStar with Cummins ISX15 and then the International ProStar with MaxxForce 13 with SCR in April. The company's portfolio of SCR-based heavy duty trucks also includes the International PayStar 5900 Set-Back Axle and International 9900i with the Cummins ISX15 engine as well as the International PayStar, TranStar, and WorkStar with the MaxxForce 13 engine with SCR.

Navistar announced in early September that it has received more than 11,500 orders for Cummins ISX engines since December 1, 2012, and more than 6,000 orders for MaxxForce 13 engines with SCR since March 1, 2013. 

International LoneStar Features
The LoneStar has been wind tunnel validated to be arguably the most aerodynamic long hood premium conventional truck ever designed. The LoneStar features exceptional ride and handling, class-leading quietness and a luxurious and functional interior. Starting at 500 hp and 1850 lb. ft torque, three ratings are available for maximum hauling power and performance.

"Customers specifically asked us for 15-liter power in the LoneStar," said Kozek. "This combination is what originally made the LoneStar popular and with the re-launch of the LoneStar with the Cummins ISX15 and SCR technology, our customers can turn heads and do so with reduced emissions and increased efficiency."
