Navistar Class 8 Vehicle Achieves Five Percent Fuel Economy Improvement

Navistar has announced its International ProStar linehaul and regional haul tractors are now available with the company’s 13-liter engine and Eaton Fuller Advantage Series Automated 10-speed transmission. The new ProStar offering delivers up to five percent in fuel economy improvement.

“Every percent of fuel economy improvement makes a difference, and pairing the aerodynamics of our ProStar with technologies from Eaton Fuller helps our customers maximize their fuel savings,” said Bill Kozek, president of North America Truck and Parts, Navistar

Additional benefits of the ProStar with the 13-liter engine and Eaton Fuller transmission include optimized engine and transmission communications, intelligent shifting and downspeeding, which allows the engine to operate at lower revolutions per minute (RPM), to use less fuel without sacrificing performance.

As part of the engine and transmission combination, the Eaton Fuller Advantage Series Automated transmission will be offered in one rating combining Navistar’s 13-liter engine rated at 450 hp and 1550/1750 lb. ft of torque for linehaul and regional haul applications in the United States and Canada.

The company’s portfolio of fully automatic and automated manual transmissions also includes Eaton Cummins Smart Advantage, Eaton UltraShift Plus and Allison TC10 transmissions.
