The widespread application of new aerodynamic technologies on tractor-trailer trucks could cut US fuel consumption by nearly one billion gallons per year,

Four TMA members—International Truck and Engine Corporation, Freightliner LLC, Mack Trucks, Inc. and Volvo Trucks North America—representing 75% of the US market for Class 8 trucks teamed with the DOE to study a variety of design improvements that would reduce aerodynamic drag and significantly improve fuel efficiency.
