The invention relates to the field of aerodynamics, and discloses an automobile wind tunnel first corner section test device which comprises a steel flow channel collection port, a corner flow deflector and a flow deflector lifting device. The steel runner collecting port comprises an airflow inlet section and an airflow outlet section, and the corner flow deflector is arranged between the airflowinlet section and the airflow outlet section. The flow deflector lifting device comprises a flow deflector lifting bracket, a flow deflector lifting truss and a flow deflector guide device. The flowdeflector lifting truss is connected to the top of the flow deflector lifting bracket. The flow deflector lifting bracket is arranged on the peripheral side of the steel runner collecting opening. Theflow deflector lifting truss is movably connected to the top of the corner flow deflector. Only the first corner section flow deflector is lifted through the flow deflector lifting device, the steelflow channel body of the fir
