COD all generations / C5 wins
I'm back as myself. I had to use my wives name Sharon because of some technical glitch.
Anyway, I never finished my topic about COD for all generation Corvettes in my last topic.
It was brought up that we were moving backwards with the new generation in every way; with I believe is not the case. Lower and wider is the way to go as far as handling is concerned. The C6 is taller and more narrow, not the way to go. It was brought up that the C6 has the lowest COD of any generation, which is simply not true. In my opinion it is obvious just by looking and comparing them. The open grille on the C6 is going to raise the drag by catching air. The C5 will not, no open grille. There are other features about the C6 that raise its COD as well. It was also brought up that aerodynamics would be measured in the same way, which is really not the case, but is very similar in final outcome. This is not to say that any generation is better than the other. Some things are timeless, if they are good, they will always be good. COD is measured in wind tunnel tests. The C6 does not have the lowest COD. The C5 does. The chart below proves the fact of the matter.

So, how does the article in Corvette Fever compare to what the factory says the numbers are for each generation?

I don't know who to believe
Who has other independent sources to verify their info?
The source that sells the product?
"Hey, mine is the best, i know because i make and sell them, why would I lie?

Interesting that Corvette Fever used the C5Z. It has a higher COD that the coupe. I read somewhere the C5 Coupe has the lowest COD of any production Corvette. Can't remember where I saw it.

I didn’t want to brag, but my car isn’t stock. I not only added muffler bearings but the exhaust bearings as well! BOTH!!!.
A tricked out special 1.73 rear end. A big wing on the back and raised it by 6 ”. The guy t the store said just those things will not only boost the HP by at least 300, will cut the drag by 25%. The guy at the store also told me not to tell anybody or so the secret will get out. Everybody will start doing it and mine won’t have any of those special features that I have. It only cost me $3,000!! He said “no pain, no gain” He said I could easily peg out the speedometer!!!!!!!

Back to the main topic.
Perhaps the C5 has a lower CD than the C6 -- but I would not be surprised if the C6 has a smaller frontal area and less overall drag.
And if they measured CD's at night................................... ..

"CDA is a better real-world number because size does come into play when we are talking about drag in terms of how much horsepower is required to reach 100 mph. So even though one car may have a slightly worse CD (C6) than another (the C5), it can actually be more aerodynamically efficient if it's smaller and has a better CDA."
