Aircraft aerodynamics presumes zero separation,low to nil form drag,and a majority of surface friction drag ruled by wetted area.
Ballistic aircraft aerodynamic drag is ruled by shockwaves.
--------------------------------------------------------------------------
Automobile drag is ruled by flow separation and the differential between the forward stagnation pressure and the base pressure of the separated wake.
Moving the separation point back is the only way to achieve the lower drag.
Lowest drag is achieved when there is zero wake.Fully boat-tailed.
While the 'front' of a car is not un-important,it is the 'rear' of the car which is most important.
