Throughout this site we use many technical terms, and given the breadth of readership our site enjoys, sometimes we are remiss and incorrectly assume everyone knows what we are referring to. For those that do not, here are some explanations of the technical terms use.
Science of the effect of air on a body moving through it. The study of physical forces at work when a body passes through the air. In the automobile world, the term aerodynamic drag is used to describe the resistance that the air exerts on a car moving at speed. By changing the body shape of a car to reduce dynamic drag, the energy output of the engine can be better utilized either in the form of reduced fuel consumption or improved performance. The French auto manufacturer Citroën pioneered the development of aerodynamic passenger cars with the DS19 in 1955, and have remained leaders in this field.
