1993 ford mustang: Coefficient of Drag 0.40 (sedan):0.36 (hatchbacks); 0.38 (GT)
i dont know if this will help but here it is any way
drag = coeficient x density x velocity squared x reference area
two
The drag equation states that drag D is equal to the drag coefficient Cd times the density r times half of the velocity V squared times the reference area A.
