ABSTRACT
The goal of this research is to emphasise the influence of the ground clearance of a car on its main aerodynamic characteristics, drag and lift. Were performed two set of measurements according with SAE requirements concerning quality of the stream in test chamber for two speeds, vair = 25 m/ s and vair = 33 m/ s , with the underbody of model reproducing a Venturi tunnel configuration. In the beginning of the paper are presented the used experimental facilities and the data system acquisition. The obtained results reveal an improving of the aerodynamic characteristics for cars with decreasing of the ground clearance, when the Venturi effect is accentuated.
