Which left only the dimensional analysis.
Some of the solar cars winning the World Solar Challenge are already using the template. The lowest drag 'car' ever measured uses it. It was relevant to them. What do I make of your comment?
The 'template' works in their wind tunnels and CFD, but not at EcoModder?

This forum is called Eco
modder.
Modifications to cars. So we're interested in what will achieve good results on our cars.
Now that the template has been proved to be largely invalid in doing that, you move the goalposts to now this site being about developing ultra-low drag cars from scratch. If we were in fact doing that, I think all five(!) low drag shapes that have been published in the literature would make good starting points.
But as far as I know, that's not what we're doing here.
