Automobile aerodynamics characteristics have great effects on cost of fuel, driving stability. Predicting it by using Computational Fluid Dynamics(CFD) technology can decrease enormously experimental time of new automobile in a wind tunnel, save large amounts of money, minimum the cycle of automotive research.The physical and mathematical models of the car-like body are set up,and the boundary condition is defined as well as the aerodynami characteristics of the body are calculated. The result generated accords with the references.
