I have to slightly disagree ChazInMT, the template is for an idealized 3D shape, and the way it's often used/abused in the forum is in 2D profile only with little consideration for the resulting vortexes. And when used, it is affecting only the upper aft canopy above the tires or pick-up truck bed.
I've explored this issue from several angles in an attempt to gain a better understanding, going from a 2-part body to a 5-part body. See thread linked to below.

If there is another way to enclose the wheels of this car without adding mass (area), I'm open to suggestion.
As mentioned in the 2012 Mustang verses the 1978 Escort thread, the frontal area is as important as anything else affecting the drag.

With a drag coefficient (cd) of just 0.24 it is better then the Mercedes Benz Streamliner with a cd of 0.25.
