Navistar, Inc. announced its International ProStar linehaul and regional haul tractors are now available with the company’s 13L engine and Eaton Fuller Advantage Series Automated 10-speed transmission. The new ProStar offering delivers up to 5 percent in fuel economy improvement.
“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.”
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.
“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 ft/lbs 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.
