AERODYNAMIC DRAG OF CARS. CURRENT UNDERSTANDING, UNRESOLVED PROBLEMS, AND FUTURE PROSPECTS

It is shown how important air drag really is when improvement in fuel economy is desired. Attention is focused on the two main properties of the body, namely air drag and weight. Realistic driving conditions are used as a baseline. From the constraints which must be observed during the design of a car, the degree of freedom left for the aerodynamicist is deduced. The components of air drag is then discussed in order to indicate present understanding of the mechanisms involved. It is shown how present knowledge about air drag is applied during the course of actual car design and development.
