Abstract: This paper reviews use of scale modelling in automobile performance evaluation. A scale model has been used to experimentally evaluate the automobile aerodynamics in a wind tunnel. Three cases have been considered, they are model without polish, model with polish and model with add-on, a load on the roof. Drag coefficients in all the cases have been computed and compared. Empirical relations can be used to predict drag coefficients on other than test speeds.
