The invention discloses an active resistance reduction shark fin antenna, a method and an automobile, and belongs to the technical field of automobile resistance reduction. Comprising a shark fin antenna, a pressurization gas storage module and a control module, the top of the shark fin antenna is provided with a plurality of gas nozzles, the shark fin antenna is internally provided with a gas injection module, and the gas nozzles are communicated with the gas injection module; a lifting module is arranged at the bottom of the shark fin antenna; the pressurizing gas storage module is communicated with the gas injection module; the control module is used for obtaining a vehicle speed signal and controlling the operation states of the air injection module, the lifting module and the pressurization air storage module according to the vehicle speed signal. The height and the jet speed of the shark fin antenna at the top of the automobile can be actively regulated according to the change of the running speed, the aerodynamic resistance of the whole automobile is reduced, and the purpose of reducing energy consumption is achieved; the problem that wind resistance of an existing vehicle is difficult to reduce is solved.
