The Influence of Wind Tunnel Tests on Body Design, Ventilation, and Surface Deposits of Sedans and Sport Cars

This paper describes wind tunnel tests with full-scale vehicles and scaled-down models. The influence of design features, air resistance, and lift on driving performance and safety are analyzed. Ventilation systems and air pressure conditions are discussed as well as the precautions taken to reduce surface deposits. The various operating modes of the new wind tunnel developed for Daimler-Benz AG are also described.
