Abstract: Models of the passenger car without and with rear spoiler (types S1 and S2) are created using SolidWorks software. The ANSYS software/Fluid Flow (CFX) module was used to analyze deeply these models based on the numerical approach in order to achieve higher speed for vehicle with maintaining the stability of the car at the same time. Results of the numerical analysis proved that the spoiler has great influence on the longitudinal stability incensement, especially under high speeds conditions. While the shape of the spoiler is not significant factor on the stability. The lift force was reduced 7.6 times when used the spoiler (type S2) compared with to the vehicle without spoiler. While the drag force was increased 12% when used the spoiler (type S2). It was analyzed the influence of existence the rear spoiler on the passenger car, as well as the effect of the shape and construction dimensions of the spoiler on the longitudinal stability. It was developed integrated approach that included the design and numerical analysis of the vehicle stability. It was proved based on the developed approach how can reduced the negative effect of some factors in order to enhance the stability of the vehicle.
