"We are pleased to see the fuel-savings fruits of this collaborative effort between government and industry," said Robert Clarke, president of the Truck Manufacturers Association. "We hope and expect that the results of this joint effort will lead to the implementation of more aerodynamic technologies on tractor-trailer trucks, which directly contributes to our nation's goal of energy independence and cleaner air."
Technologies that improve truck aerodynamics in several key areas were displayed today outside the U.S. DOE headquarters, including:
The two-year study was funded by the U.S. Department of Energy FreedomCAR and Vehicle Technologies Office through the National Energy Technology Laboratory. Clarke applauded the government-industry joint effort, saying, "The truck manufacturing community greatly values the government's support of efforts like this one and looks forward to expanding the scope of cooperative research in the future."
The combined effect of all aerodynamic improvements on one vehicle could result in as great as 23 percent reduction in aerodynamic drag. For every 2 percent reduction in aerodynamic drag, there is a 1 percent improvement in fuel efficiency.
"To put this in perspective, if every tractor/van semi-trailer combination truck in operation in the
