“Aerodynamics” mostly used for the airplanes and the science of applied aerodynamic is to improve airplanes and automobiles both. Aerodynamic concept of cars is studied with computer modeling and wind tunnel testing.

Main reason to use aerodynamics in cars are to decreasing the drag, noise of wind, minimizing emission of noise, avoid lift force at high speeds. Aerodynamic concept cars integrate wheel arcs and their lights for small surface. Fastback are used in these cars to cross the air pressure smoothly, means they don’t have spiky edges. To produce downward force of aerodynamic, smooth and flat floor is used in the cars. Air smash into engine bay is used for incineration and cooling, and then move out under floor. Aerodynamic concept cars needed a seal from high pressure which surrounded the gear box to low pressure which surrounded the wheels. These cars are well known for fuel efficient and safer for passengers.
