WebDrag coefficient (C d) is a commonly published rating of a car's aerodynamic smoothness, related to the shape of the car. Multiplying C d by the car's frontal area gives an index of total drag. The result is called drag area, and is listed below for several cars. The width and height of curvy cars lead to gross overestimation of frontal area.
