I found the teardrop image in your
gallery:
It may be a distortion in the photograph, but that image is actually more like 2.7 to 1. So I corrected it back to 2.5 to 1 in photoshop (not the original - just the following picture) and then followed your instructions to compare these cars:
Your CRX is the closest example of following the shape.
Most surprisingly, the excellent GM EV1 is the furthest from the "ideal" profile!
Kamm's own design follows very closely up to the last 20% of the roof line where it dives down. (All these cars - except mine - are in your gallery ... "other vehicles 1 & 2".)
And for my design, it's not perfect. It's not very clear from this picture, but there's a diverging gap between the cardboard and the teardrop "outline" roughly comparable to the Prius & Insight examples. I'd still like to tuft test it before raising it up though.
