The invention discloses an empennage capable of reducing wind resistance and a vehicle with the empennage. The empennage comprises an empennage body, a first air supply part, a flow guide part, a mounting part, an empennage lower body and a second air supply part. The spoiler body comprises a first air supply part, a flow guide part and a mounting part which are connected, the flow guide part is arranged between the first air supply part and the mounting part, and the flow guide part is suitable for guiding gas flowing through the surface of the flow guide part when an automobile moves; wherein the first air supply part is provided with an air supply curved surface, the projection plane of the first air supply part in a coordinate system XOZ is an air supply plane, the air supply plane is provided with a coordinate point M close to one end of the first air supply part, and the included angle between the tangent line of the coordinate point M on the air supply plane and the X-axis direction ranges from 12 degrees to 17 degrees. When the vehicle runs at a high speed, the structure can reduce the size of the trailing vortex at the tail of the whole vehicle, reduce the wind resistance of the whole vehicle and increase the pressure at the tail of the vehicle.

    本发明公开了一种可降风阻式尾翼及具有其的车辆,包括:尾翼本体、第一送风部、导流部、安装部、尾翼下本体和第二送风部。尾翼本体包括相连接的第一送风部、导流部和安装部,所述导流部设置在所述第一送风部与所述安装部之间,所述导流部适于引导汽车运动时流经其表面的气体;其中,所述第一送风部具有送风曲面,在坐标系XOZ的投影面为送风平面,所述送风平面具有靠近所述第一送风部一端的坐标点M,所述坐标点M在送风平面上的切线与X轴方向的夹角为12°‑17°。此结构在车辆进行高速行驶时,能够减小整车尾部尾涡大小,降低整车的风阻,增大汽车尾部的压力。
