This article discusses how the principles of aerodynamics can be used to improve the efficiency of cars. It has been found that, as a rough rule of thumb, a 10% reduction in drag can result in about a 3% increase in fuel economy in EPA composite testing. Basically, there are two ways to reduce drag: reduce the frontal area and reduce the drag coefficient. Since there is a limit to how much the frontal area can be reduced, it's a maximum reduction in drag that the aerodynamicist must seek.
