When a car is traveling at high speeds, according to aerodynamic principles, it encounters air resistance. This creates three aerodynamic forces around the car's center of gravity: longitudinal, lateral, and vertical. The longitudinal force is considered the main aerodynamic force.
To effectively reduce and overcome the effects of air resistance at high speeds, rear wings are designed. Their function is to create a fourth force on the car: a greater adhesion to the ground. This force offsets some of the lift, effectively controlling the car's buoyancy and reducing the drag coefficient. This allows the car to stick closely to the road, thereby improving driving stability.
