I would guess 1 count means 1 pound of drag.

I think Chevy got the marketing down packed now. They see if they market a car real good, then it will sale. Not to mention the Camaro pretty much is a hot commodity and could pretty much sale itself, but marketing does help alot.

What is 1 count of drag mean???

Either way I'm glad they made all these improvements. They'll really pay off when I drive it to work each day.
http://en.wikipedia.org/wiki/Drag_count

Quote:
A drag count of 1 is equal to Cd of 0.0001. So if, for example, the steady state drag coefficient is 0.0200 and someone sticks a hand out the window adding 5 drag counts, the new drag coefficient would be:

0.0200 + 0.0005 = 0.0205 or 205 drag counts.

Drag count is used as a crude measure for the change in drag coefficient (it is not a direct measure of drag as it is associated with a reference area, it is only valid for use as a relative assessment of change).

Not to go off topic, but why do you think that GM decided not to put a true racecar driver to lap the ring? I am just curious. I do not know the background of the driver who did the 7:41 but I know its not a racecar driver. Im almost willing to bet that this car very well could have done a 7:35 or so.. In any event, extremely impressive time coming from someone who does not race cars for a living!!!

From what I have heard, he was not a "Professional" but none the less, is a fantastic driver that happens to work for GM

Here is a video of him talking about the new Cadillac ATS, which I think is their version of the ZL1

Yes, I know it doesnt matter, but I was just curious as to why not? Maybe it didnt matter to GM or maybe they wanted to leave a little on the table (other manufacters stating "could you believe what they would have got if they used a racecar driver?"). Again, I was just curious and wondered if there was any true reasoning behind it that I may have missed.

thought ATS was the next gen platform... CTS-V is Caddy's ZL1.

After watching videos of the ATS I would have to disagree.
The same developers of the ZL1 are here talking about how Cadillac needs to be above and beyond anything else they have today.

I don't understand how that makes a difference. They're always trying to make tomorrow better than today. ATS is Alpha based and next generation, while the 2012 ZL1 will be Zeta based. There could very well be both a -V and ZL1 on the Alpha platform as well, but I still see the -V as the ZL1 of the Caddy.

Does increased downforce, which helps decrease drag, improve fuel economy?
