In this study, AVWT (Automatic Virtual Wind Tunnel) is developed to estimate of vehicle aerodynamic performance. For the first step of using AVWT, engineer set boundary condition and mesh condition on the main window. As engineer executes AVWT, aerodynamic analysis of vehicle is performed from pre process (mesh generation) to post process automatically. In order to secure the accuracy of AVWT, drag coefficient values of using AVWT are compared with those of experiment for the three typical DrivAer models (Notchback, Fastback, and Hatchback). As a result, the error of the difference between the result AVWT and experiment is less than 5%
