Navistar adding SCR to MaxxForce 9, 10

Jason Cannon March 7, 2014

Navistar, Inc. says it plans to expand vehicle enhancements and powertrain choices on International brand vocational truck models and add selective catalytic reduction (SCR) emissions technology to its high horsepower mid-range engines beginning this summer.

The company’s medium-duty SCR transition began in September 2013 with the International DuraStar and the Cummins ISB 6.7 liter engine. Navistar says MaxxForce 9 and MaxxForce 10 engines with SCR will be available exclusively on the International DuraStar and 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,” says Bill Kozek, President, North America Truck and Parts, Navistar. “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 9-liter and 10-liter engines.”

The International TerraStar, 2014 ATD Medium-Duty Truck of the Year, will also be offered with added enhancements. The Allison Optimized 1000 Series transmission with an optional 6th speed is now available exclusively on the TerraStar. With the addition of the 6th speed, the close ratio, fully-automatic transmission offers improved fuel economy, lower engine noise and optimized performance, the company says. The TerraStar also features a refined front suspension with a redesigned front spring and bumper. The company says the suspension offers a smoother ride especially when driving over rough terrain.

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.
