This paper discusses the aerodynamics of a generic, enclosed-wheel racing-car shape without wheels investigated numerically and compared with one-quarter scale wind-tunnel data. Because both methods lack perfection in simulating actual road conditions, a complementary application of these methods was studied. The computations served for correcting the high-blockage wind-tunnel results and provided detailed pressure data which improved the physical understanding of the flow field. The experimental data was used here mainly to provide information on the location of flow-separation lines and on the aerodynamic loads; these in turn were used to validate and to calibrate the computations.
