Abstract
In this experimental study, we have analyzed aerodynamic performance of the four representative types of passenger car vehicles, different types of side window angles, different types of engine hood angles, and the angle difference of the roof line in order to comprehensively analyze how the aerodynamic performance varies with different shape of vehicle. Experiment results showed that the rear window falling at aa certain angle lowered aerodynamic performance, angle difference of the lowered roof line did not affect aerodynamic performance, and the back window line falling at certain angles had no visible effect on aerodynamic performance. Back window line leaning towards front side may help enhance styling aesthetics, but aerodynamic performance decreased. In case of rear diffuser installation, aerodynamic performance also decreased.
