In this article we have to intend an effective numerical model based on the Computational Fluid Dynamics (CFD) method to obtain the reduction in drag forces around a passenger car with Spoiler & VGs together. This experimental work of the test vehicle and grid system is constructed by ANSYS-14.0. FLUENT which is the CFD solver & employed in the present work. In this study, numerical iterations are completed, then after aerodynamic data and detailed complicated flow structure are visualized. In this work, model of generic passenger car has been developed in solid works-10 and generated the wind tunnel and applied the boundary conditions in ANSYS-14.0 workbench then after testing and simulation has been performed for the evaluation of drag coefficient for passenger car. In another case, the aerodynamics of the most suitable design of Spoiler and VGs both are with the passenger car and analyses for the evaluation of aerodynamic coefficients for passenger car. The addition of spoiler with VGs results in a reduction of the drag-coefficient 4.35% and lift coefficient 18.83% in head-on wind. Hence, the drag force can be reduced by using add on devices on vehicle and fuel economy, stability of a passenger car can be improved.
