U R welcome. Yeah, just normal driving should not be an issue. Glad to hear that so far everything is AOK!!!Wow..another one.
My 17 is supposed to be out of that mess but who knows. It’s not being tracked and 1600 km street use and no issues so far. Of course it was the same for my 15.
Got to recognize the misery of the guys buying them and not being able to track the car though.
The comments section underneath is more entertaining than the article.
Good post though. Thanks.
Have you tried the DEI heat blanket on the catalytic converter?Flyboy,
congrats on the car.
Driving the twistys is one thing; tracking it is another.
On a track we are using 2nd, 3rd, 4th, 5th gears, and revving up to redline, repeatedly.
This is what is causing the overheating... especially in an A8.
The supercharger is pumping that gas/air mixture in at an increased volume,
which then creates hotter burn (and power), which heats the engine coolant up more,
and creates hotter exhaust. Combine that with the A8 transmission now working harder,
along with its cooling lines going through the radiator... all this is causing the engine temps
and transmission temps to climb. Once they hit that "magic" threshold... bingo... "Limp mode".
Yep that sucks for sure. Time to pick up a Viper for a track car and use the Vette as a daily driverI haven't, but another person I know has tried the GM attempt at wrapping the exhaust.
Still not anywhere near enough.
Essentially we need to get MUCH more cooling at the radiator/coolant,
and install a separately plumbed transmission cooler.
For the M7 cars, the separate transmission cooler can be installed behind the
right front bumper fascia.
But for the A8 cars, that space is already taken up by the A8 transmission cooler.
Take a look at the new ZR1... GM has addressed this overheating issue with extra
cooling behind both sides of the front bumper fascia. And there are additional separate
(not plumbed into the radiator) coolers for the transmission.
Actually LG motorsports has a "package" solution... but it is over $10K US.
Others have provided partial solutions... a larger radiator, a larger transmission pan
to coerce more transmission cooling, etc.
It's really frustrating for us who track the car..... take 3 or 4 hot laps,
then cool it down for 3 or 4 laps. Conservatively use 3rd, 4th, and don't push to
redline too much.

ddgermann said:They found the solution to this issue and said it is in the driving method. I drove the crap out of a 17 Z06 M7 there for 2 days and never had a problem in 85 degree temperatures. Although I was not doing mega laps only a few at a time full on.
For all its worth? It's worth alot..thanks for the reply and fully agreed.It's never been much of a headline on our forum, and we have a lot of 2015 and 2016 Z06 owners. To my knowledge no one here has had much for a problem. But that being said, it's my opinion (for all it's worth) that in some areas, for every one that has an overheat issue, a hundred more will jump on a Class Action Law suit. For the ones that do have an actual problem, hopefully it gets ratified.
