Sports cars are designed in such a way that the drag force experienced by them is minimal. Drag is the component of the aerodynamic force parallel to the relative wind, or free stream velocity, acting on the center of pressure of a body. The drag is a force that slows down a moving body. The more streamlined a body is the lower would be the drag acting on it.
