The invention discloses an automobile downward pressure adjusting device which comprises two tail wing devices, an airflow channel and a hydraulic pipeline. The tail wing devices are located at the tail end of the airflow channel. Each tail wing device comprises a main wing, an auxiliary wing and a driving mechanism, wherein the main wing is located below the auxiliary wing, a plurality of upward-extending auxiliary wing positioning plates are arranged in the middle of the main wing, the upper ends of the auxiliary wing positioning plates are hinged to the tail end of the auxiliary wing, and the front end of the auxiliary wing is close to the tail end of the main wing; and a vertically-arranged rotating plate capable of rotating relative to each main wing is arranged in the middle of each main wing, and the other end of each rotating plate is hinged to the middle of the corresponding auxiliary wing. The driving mechanism comprises a main wing cylinder, an auxiliary wing cylinder, a rotating auxiliary cylinder and a base. The hydraulic pipeline comprises a hydraulic pump, a main wing pipeline, an auxiliary wing pipeline and a rotating auxiliary pipeline. According to the automobile downward pressure adjusting device, air resistance and downward pressure on the left and right sides of the tail of an automobile can be adjusted, so that the adhesion property of the automobile is improved, and tire loads are lowered.
