Want low drag? Don't follow a template.

But isn't that his point entirely? That low drag can be achieved without the/a template?

It is irrelevant whether it was for styling or drag, it achieves low drag, and doesn't follow the template.

"I have understood there can be attached flow with even steeper curves, but the the lowest drag is achieved if you follow the template." where is the evidence for this claim?

The template, I am pretty sure, without wheels, theoretically has a drag coefficient of 0.09.

Many solar cars with wheels, that are real, have drag coefficients around and lower than 0.09. But also none, of the many papers I have read about solar car design, say "we used an arbitrary template as the starting point".

I don't see what is relevant about being a mechanical engineer, mechanical engineering and aerodynamics are completely different things.

(I am not saying the template is useless, but it has many claims, and I have seen contrary evidence elsewhere in scientific research papers (not just in Julian's videos))
