The aerodynamics of the automobile is the study of the aerodynamics of road vehicles. Its main objectives are to reduce drag and wind noise, minimize noise emission and prevent unwanted lifting forces and other causes of aerodynamic instability at high speeds. Air is also considered a fluid in this case. For some classes of racing vehicles, it may also be important to produce aerodynamic force to improve traction and, therefore, cornering capabilities.
The drag force of the aerodynamic drag increases significantly with the speed of the vehicle. As early as the 1920s engineers began to consider the shape of the automobile in reducing downforce at higher speeds. In the 1950s, German and British automotive engineers systematically analyzed the effects of automotive friction for higher performance vehicles. In the late 1960s, scientists also realized the significant increase in sound levels emitted by cars at high speed. It was understood that these effects increased the intensity of sound levels for land uses adjacent to a nonlinear rate. Soon highway engineers began designing highways to consider the effects of drag speed produced sound levels, and automakers considered the same factors in the design of the vehicle.
