This is the normal Aerohead extrapolation from justifiable data to unjustifiable application.
The shapes Aerohead described are just that - shapes. They are not cars - or even vehicles of any type.
They are not in proximity to the ground; they of course do not have wheels or cooling openings or doors or surface roughness. Three of the shapes have perfectly circular cross-sections.
The lift of the shapes is not shown; nor is the drag when there is a yaw component to the airflow.
To me this is all a bit like showing a picture of a coil spring, stating the equation for coil spring stiffness - and then saying:
The take-away, is that because of this equation, anyone desiring to know the state-of-the-art for coil spring design, has available to them, off-the-shelf technology, from which to design the suspension of their project from the get-go.
