If anyone has measured the CdA of their cars before and after aeromods, I'd love to see your results.

I measured the Cd of my modified 2003 Beetle some years back. (By coast-down) I have my calculations around here somewhere, but no clue where to find them. Result: Cd = 0.31 with the modification. I didn't measure before, but the published number is 0.38.

Tim, mind if I try to move this onto the EM wiki so people can edit it themselves?

That would be great Ben. I had talked to Darin about it before and we basically put it on the back burner.

1995 Alfa Romeo 146

Cd = 0.31 (source: internet forum)
Width = 67.4in / 1712mm (source: Alfa)
Height = 56.1in / 1425mm (source: Alfa)
Frontal area = 22.06 sq ft / 2.05 sq m (using 0.84 multiplier)
CdA = 6.838 sq ft / 0.635 sq m

I think I got my sums right!

Currently working on converting it to the wiki for community editing. Might take a while to brute force the formatting

Well, that took quite a few hours: Vehicle Coefficient of Drag List - EcoModder

Should simply adding and editing things, though

Added Jeep Wrangler to the list. Its really pathetic to look at next to everything else on the list Anybody else got info for Cherokee, Grand Cherokee, Liberty, or YJ and CJ models? I believe YJ was actually worse(its hard to believe.) Also, I'm gonna try to get top off Cd.
