Navistar has announced that it continues to invest in its severe service and medium duty product lines by expanding vehicle enhancements and powertrain choices on International brand vocational truck models.
In addition, the company will add selective catalytic reduction (SCR) emissions technology to its high horsepower mid-range engines starting this summer.
The company’s medium-duty SCR transition began in September 2013 with the International DuraStar and the Cummins ISB 6.7L engine.
MaxxForce 9 and MaxxForce 10 engines with SCR will be available exclusively on the International DuraStar and International WorkStar vehicles.
“Our medium-duty transition to SCR started strong with our DuraStar with Cummins ISB6.7 and we have high expectations for this chassis/engine combination as we see the construction market continue to rebound,” said Bill Kozek, Navistar’s president of North America Truck and Parts.
“We also know a number of our customers require more horsepower and torque and we’re pleased to offer these customers an expanded engine choice by adding SCR to our 9L and 10L engines.”
The International TerraStar, the 2014 American Truck Dealers Medium Duty Truck of the Year, will also be offered with added enhancements.
The Allison Optimized 1000 Series transmission with an optional sixth speed is now available exclusively on the TerraStar. With the addition of the sixth speed, the close ratio, fully-automatic transmission offers improved fuel economy, lower engine noise and optimized performance, noted Kozek.
The TerraStar also features a refined front suspension with a redesigned front spring and bumper. The suspension offers a smoother ride especially when driving over rough terrain, he said.
All International vocational trucks also feature the International Diamond Logic electrical system, a customizable truck computer module that integrates communication between the truck and exterior equipment like plows, dumps and spreaders.
Navistar announced earlier this week that it now offers new Diamond Logic feature bundles for the vocational market to help customers quickly identify the most widely used controls and then customize to their needs.
