The invention provides a racing car tail wing and a racing car, and belongs to the technical field of aerodynamics. The racing car tail wing comprises a main wing plate, side wing plates, a cylinder and a driving mechanism, wherein the main wing plate comprises a first arc-shaped curved surface, a second arc-shaped curved surface and a transition arc surface smoothly connected to the front ends ofthe first arc-shaped curved surface and the second arc-shaped curved surface, the curvature of the first arc-shaped curved surface is smaller than that of the second arc-shaped curved surface, and arotating cavity with slits in the upper portion and the lower portion is formed in the front end of the main wing plate; the side wing plates are symmetrically arranged at the left end and the right end of the main wing plate; the cylinder is arranged in the rotating cavity, the center line of the cylinder coincides with the center line of the rotating cavity, and the upper arc face and the lowerarc face of the cylinder protrude out of the corresponding first arc-shaped curved surface and the second arc-shaped curved surface through the corresponding slots. The driving mechanism is connectedwith the cylinder and used for driving the cylinder to rotate. According to the racing car tail wing, the wheel road holding effect can be improved, and the effective work of a propelling system is improved.
