| This CFD output of a R35 GTR shows wake turbulence and form drag. These are both pressure induced drag phenomena. |
Drag equals= ½ D x Cd x A x V squared
Where D equals air density, A is the frontal area of the car, Cd is the coefficient of drag (which is often commonly published for a car) and V is the velocity of the car relative to the air. A car like the R35 GTR has a Cd of .28 and a crappy car like an old B13 Sentra has one of .42.

| Some drag coefficients of common shapes. |
In short, less drag means more speed with the same amount of power. Sometimes in the quest to kill lift and make downforce we may increase drag. There are some tricks that can be done to reduce drag. Sometimes you must balance drag and downforce together to get the best compromise for the best performance. Stay tuned, in the future we will explain some common aerodynamic tricks and devices that you can use to improve your performance. Some are actually cheap and easy for you to make yourself.
