These numbers use a baseline Cd of 0.25, which is a stock Insight with mirrors, grille openings, and stock underbody coverage.

I'm seeing the stock Insight at 30 % aft-body.
If I use Cd 0.25 and add the Sunraycer's original wheel fairings,I'm seeing Cd 0.241 at stock length.
If I run the tail out to 50 %,and with cooling system mods( ductwork) we might be looking at Cd 0.163.
With a one-wheel range-extender trailer with gap-fillers taking it out to 80 % template,Cd 0.119.
