I'll be posting some 'streamlined' cars of the past,soon I hope,and you'll see that some were designed for plan-view,with fineness ratios which would mimic a streamlined section,rather than a streamlined body of revolution.
A section of 3.92:1 has the lowest drag,so the boat tail angles are more generous.

Hmmmm...... I think we have a different objective. I am after BUILDING a car. I am looking for information to help me build my cars.
For my purposes, 22 is not an acceptable number as I don't think it will work in the real world.
And I don't have a windtunnel, so I'm after something pretty simple to implement.
