Drag Coefficient

The drag coefficient or C sub d, is the number given to quantify the drag (resistance) of the vehicle through the air. It is a key design element of any vehicle, but only half of the equation of the vehicle's true aerodynamic ability when considered without the frontal surface area of the vehicle.

Here are some of the drag coefficients of the most basic shapes:
