The invention discloses a deformable tailfin system which comprises two tailfin structures, airflow channels and hydraulic pipelines. The tailfin structures are arranged at the tail ends of the airflow channels, and each tailfin structure comprises a main fin, an auxiliary fin and a drive mechanism, wherein the main fin is located below the main fin, the front end of the auxiliary fin is close to the tail end of the main fin, the ends of the same sides of the main fin and the auxiliary fin are both provided with an end plate, the main fin is fixedly connected with the corresponding end plate, and the auxiliary fin is rotatably connected with the corresponding end plate. Each drive mechanism comprises an auxiliary fin cylinder and a base, wherein a rotation auxiliary cylinder is arranged on the base. Each hydraulic pipeline comprises a hydraulic pump, an auxiliary fin pipeline and a rotation auxiliary pipeline, wherein the auxiliary fin pipeline is used for connecting or disconnecting the two auxiliary fin cylinders at the same time, and the rotation auxiliary pipeline is used for switching on or switching off each rotation auxiliary cylinder independently. Multiple parallel strip-shaped through holes are formed in the front side of each end plate and located above the corresponding auxiliary fin. The deformable tailfin system can adjust the down force and air pressure on the left side and the right side of the tail portion of an automobile, so that the adhesion property of the automobile is improved, and the tire load is lowered.
