In the case of road cars, road safety is the primary factor. The geometry of high-speed road cars has no regulatory restrictions. In addition to the high engine power and effective shape, they can use various types of additional movable aerodynamic e

The aim of this study was to extend the safety limits of fast moving cars by the application, in a controlled way, of aerodynamic forces which increase as the square of a car’s velocity and, if left uncontrolled, dramatically reduce car safety. Thi

In this paper, experimental and numerical results are presented on an active car wing with a moving spoiler placed beneath it. It was shown that movement of a small element, i.e., the spoiler, can result in a significant change of downforce generated
