The present work deals with aerodynamic drag reduction of an urban-concept car for energy-efficient competition. Several modifications have been proposed to the original design of the urban-concept of the car. In order to investigate the effect of the proposed modifications numerical method has been developed. In the numerical method three-dimensional governing equations have been solved numerically. Turbulent flow is modeled using k-epsilon model. The two designs have been simulated at five different inlet velocities. The inlet velocity varies from 10 m/s to 20 m/s. The velocity contour, velocity vector and pressure distributions have been plotted. The results show that the proposed modifications improve the performance of the proposed design. At the given inlet velocities, the aerodynamic drag coefficient of the new design decreased 26.63 % in comparison with original design. It is recommended to modify the original design of the urban concept car by implementing the proposed modifications. The new design will improve the performance of the urban concept car.
