This study reports aerodynamic computations of a model car body using various turbulence models. Simulation results were compared with data from wind tunnel tests, for two rear slant angles. The results indicate that RSM simulations gave slightly better predictions of the drag coefficient in both cases. All turbulence models performed reasonable well for the 25° case. However, none of the models could predict observed separation on the rear slant in the 35° case. Consequently, they all failed to predict the massive recirculation zone in the wake.
