I wrote this down one time, I don't know where it came from but here it goes: The CD for a 240Z is .476 , and that there is under 20 sq ft of frontal area.

Such beautiful lines on what is that a 240-Z?

Somewhere I have a C of D link bookmarked with many cars listed, did a search and the best I could find is the above.

EDIT: .41 to .42 isn't all impressive for this VW (better than the Z's near .48), and I assume it has a more or less flat floor pan too. I'll admit that a bit perplexed by some of this.

Looks like it might be the SP2 from the profile

Still better C of D than a brick though, right?

I was showing brick-like vehicles when I started this thread, suppose we could or should keep to that theme?

It's your thread of course, but that would exclude thin-fendered, wedge shape vehicles.

Not at all, show whatever sucks, but it is disappointing to see my beloved 240Z pictured. I don't drive it for mileage though; it's a track racer and the bad aero helps me take load off my brakes entering the turns.

Hi my motorhome must come under the heading UNAERODYAMIC but freebeard has given me some pointers to help clean it up. Look at my profile and hope it has photo of it.

So what's worse, a Cd of 0.42 and A of 20 (rough guess for 240Z area) or Cd of 0.21 and A of 50 (typical SUV area)?

[freebeard]

A 0.21 Cd SUV might be a stretch limo with a fineness ratio of 2.78:1 or whatever.

I guess the Clark Cortez I owned qualifies as a brick ...with an 8" bevel on the windshield edges.

How about that one ?

I'd love to see this disaster in a windtunnel.
