Increased fuel efficiency for ProStar

International Truck & Engine Corp. has announced its new heavy-duty ProStar Class 8 tractor benefits customers with more than 4% better fuel economy “than the nearest competitor.” This is thanks to the ProStar demonstrating 9% less aerodynamic drag, International said.

To get the most fuel efficiency, International recommends spec’ing trucks with patented features including:

· A “pod” air fairing on the roof, which reduces drag by up to 20%, allowing for up to 10% improved fuel economy.

· An aerodynamic mirror that can reduce drag by up to 2%, allowing for up to 1% improved fuel economy.

· Chassis skirts that run along the side of the cab and cover the fuel tank and battery box reduce drag by as much as 7%, allowing for a 3% improvement in fuel economy.
