Navistar announces 5 percent fuel economy improvement with ProStar

Navistar said that its International ProStar tractors equipped with the company’s 13L engine and an Eaton Fuller Advantage Series automated 10-speed transmission is achieving a 5% increase in fuel economy compared to a 2011 ProStar.

Navistar made the comparison of a model-year 2015 ProStar powered by the 13L SCR engine with the Eaton Fuller Advantage  transmission to a model-year 2011 ProStar powered by 13L EGR engine and a 10-speed manual transmission, the company said.

“The increased availability of automated transmissions helps us address the driver shortage issue by reducing the variance between experienced and inexperienced drivers,” said Bill Kozek, president of North America Truck and Parts, Navistar. “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.”

According to the company, additional benefits of the ProStar with the 13L 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.

“The benefits of automated transmissions have driven considerable acceptance in the industry,” Kozek added. “Automated transmissions now make up 30 percent of the market in North America with the trend continuing upward.”

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