LISLE, Ill. — Navistar has announced its International ProStar with 13L engine and Eaton Fuller Advantage Series 10-speed automated transmission now delivers up to a 5% improvement in fuel economy.

The combination is now available for order.

“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.”

Other benefits include optimized engine and transmission communications, intelligent shifting and downspeeding, which allows the engine to turn at lower rpms, saving fuel.

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

This package will be offered with Navistar’s 13L engine rated at 450 hp and 1,550/1,750 lb.-ft. of torque for linehaul and regional applications in the US and Canada.
