Reductions of aerodynamic drag in the 20-25% range through the use of several established drag-reduction devices and minor design changes have been demonstrated on three large sales-volume 1974 and 1975 model American automobiles. Comparisons of test techniques were made by testing one automobile both full-scale and as a 0.4-scale model in two different wind tunnels. Another vehicle was tested both full-scale in a wind tunnel and by the coast-down technique. Good comparative results were obtained.
