Drag Coefficient?

[alleydude]

Does anyone know what the advertised drag coefficient is on the stock '84-90 and '91-96 'Vettes? I can't seem to find that information anywhere, and I'm curious how it compares to other cars.

From the Tech Center Knowledgebase on this site, the drag coefficient for the C4 is 0.33.

Actually it was from the Model Center.

Thanks for the help. I couldn't find it, and the '91 data is very incomplete.

Re: Drags...

Coefficient of drag by years:

'73 .325 (X-882 Mid-Engine 4-Rotor Wankle Corvette)
'80 .443
'84 .34
'86-'90 .33
'91 .29
'96 .31
'97 .29
'98 .29/.32 (Conv't)
'99-'03 .29/.32/.31 (Fixed Roof Coupe)

GM Precept a five-passenger diesel-electric sedan's CE is .163.

Interesting figures, for sure. I hope this isn't too stupid of a question, but how do these figures compare to a "regular" modern sedan. Like, .31 for my '96 sounds like a cool number, I don't have any reference point to compare it to, therefore it means nothing to me.
