Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object.
Automotive aerodynamics is the study of the aerodynamics of road vehicles.
The best way to improve a car’s aerodynamics is by reducing its drag.
Downforce describes the downward pressure created by the aerodynamic characteristics of a car that allows it to travel faster through a corner by holding the car to the track or road surface.
It is very important to produce a good downward aerodynamic force because it affects the car’s speed and traction.
The most aerodynamic cars are streamlined; meaning that they would have no sharp edges.
Automotive aerodynamics can be studied by using computer modeling or by testing the car through wind tunnels.
The wind tunnel includes a rolling road which moves at the same speed as the air flow.
Drag Coefficient is a commonly published rating of a car's aerodynamic smoothness, related to the shape of the car.
Multiplying a cars drag coefficient by the car's frontal area, gives an index of total drag and is sometimes referred to as drag area.
