"08 Owners please HELP!!!
My apologies to all of you and to Road & Track. My brother lied! That was his idea of a joke. Guess you all know what I feel like! 
The original message was:
Is it true '08s have A/C issues??? Although I haven't gotten the latest Road & Track, my brother sent me this very disturbing quote:
"The Corvette Z51, ostensibly reworked for 2008 to appeal to the more enthusiastic driver, includes a number of controversial features that GM doesn’t trumpet with anything approaching the sonorous tones of the LS3’s optional performance exhaust system. Of utmost concern to those of us—and we know who we are, don’t we?—who thrive on performance, is the inclusion in the United States of vehicle technology designed for the European market. This technology, effectively designed to reduce CO2 emissions, disengages the air conditioning compressor whenever the driver accelerates above a factory-set marker. This marker continually adjusts based upon on-board computations that measure a number of variables including acceleration, fuel consumption, as well as ambient and engine temperatures. While admirable from a technological standpoint, this renders the new Corvette nearly undrivable in hot-weather climates such as Las Vegas and Palm Beach."
If this is true, I'm going to seriously think of killing my order for an '08!

That is nothing new, high performance GM cars have had that feature for a very long time. I remember my 95 Trans Am did the same thing, whenever you went full throttle the AC compressor would disengage above a certain rpm. They do this to protect the compressor from being spun too fast.

I've had my 08 for about a month now, and its hot out. Upper 90's all week. The AC has worked perfect.
Although a couple years ago when I had my 05 I ran it at the drag strip. The first run I decieded to keep the AC on, just to see what it would run with it on. I noticed at the end of the run it was shut down.
It must shut down right at red line, which I don't get close to during normal street driving.

It's been 100° here for the last 2 days. No problem with my 06 that shuts off the A/C compressor when you go WOT.

GM has been doing this in some fashion or another since the 80'S.. What are you getting so worked up about??? AND if its done in stuffy old Europe, you think the frogs(french) wouldn't complain.. CHILL..

I know that it's been a common practice to shut down the A/C compressor at WOT on many cars for many years. My '94 Mustang GT did that. This is obviously a different issue. Maybe some people missed this part of the quote:
"This technology, effectively designed to reduce CO2 emissions, disengages the air conditioning compressor whenever the driver accelerates above a factory-set marker. This marker continually adjusts based upon on-board computations that measure a number of variables including acceleration, fuel consumption, as well as ambient and engine temperatures. While admirable from a technological standpoint, this renders the new Corvette nearly undrivable in hot-weather climates such as Las Vegas and Palm Beach.
Now I don't know about some of you, but I was around when things like this reared their ugly heads back in the '70s. Cars got to the point where they barely ran at all.

I've got an 08 Z51 M6.......picked it up about 2 weeks ago.
It's been in the upper 80's to mid 90's just about every day here in the Chicago area.
The air conditioning has worked great - very cold.
Don't even give it a second thought.
You're going to absolutely love the car.

What they wrote about was a theoretical interpretation of engineering information they obviously didn't understand. They don't say that they actually experienced that problem.
All cars are hot tested at desert proving grounds. Do you really think one of the big three would sell a car that the A/C didn't work in hot climates?
Or is a magazine writer sitting in a cubicle reading technical data coming up with a controversial spin to put on something he knows nothing about.
I've ridden in 08's on blazing hot days, the A/C works fine.
Cars in recent years have used more complex ways of determining when to momentarily disable A/C. It used to be, cut and dry, at WOT the A/C clutch disengaged. Not so anymore, now many factors are taken into the calculation. Many have noticed the LS2 if you just go wide open briefly the A/C doesn't disengage. But hold it wide open long enough and it might disengage briefly.
Nothing new, just another missinformed rag writer.

Alot of cars have this "feature" - My Nissan maxima used to shut down the compressor at high revving speeds above 120 -
Dont drive like a nut with the A/C on anyway , bad for the car.....
