I don't think the old Dodge Daytona and Plymouth Superbird come anywhere close to fitting the aero-template.
Have these Cd numbers ever been independently tested and verified?
Yea, the wing was so tall so that the trunk would open, and just had to be a drag source too.

I found this, in an attempt to answer my own questions.

FINALLY!! Production 1969 Dodge Charger Daytona in a wind tunnel
Quote:
This is the car from the WPC Museum, so the scoops do not have openings, since the car has 70 Charger fenders on it.
Nevertheless, here's a photo to accompany the words below:
(this was probably the first test ever for a production Daytona [according to Romberg, they were focused on the race vehicle]; the 0.37 CD was also exceptional for its period, and also the vehicle came in at -0.14 rear lift thanks to the 23 inch rear wing).
So - THIS production Daytona measured at .37
The .29 figure we have all learned to quote is for the much lower RACE version with side glass.
The .29 appeared on the Daytona drag study graph prepared by Gary Romberg and found in the "F" body aero study booklet..............
I got this email with the photo from the Chrysler tunnel. I have no further info on details
other than the posted quote and that it happened in June, 2012! What's a few years waiting for info like this?

FINALLY!! Production 1969 Dodge Charger Daytona in a wind tunnel
Quote:
Don't see a plain old CD number. But the old paperwork references CdA (Drag coefficient x frontal area) for comparitive purposes from a 1971 performance estimation memo:
Wing Cars 7.0
1971 race cars 9.5 (Street Road Runner 10.2, Dodge 11.2 - both with windows up)
1970 standard body cars 10.3
The G-series tunnel tests say the standard 1971 cars had roughly 300 hundred pounds more rear lift compared to a Daytona.

Can someone reverse the math and deliver a Cd number to us?
