Pobst and MT liked it!

This does not bode well for track rats: "when Pobst pulled back into the pits after his fourth lap, it wasn't because he wanted to stop. The car had flashed an oil-temperature warning on the back straight."
Over temp in 3 laps?

^ That's a bad sign.. car will be a rocket for the flyer TT lap, but won't be able to last a full HPDE session with an instructor or very advanced driver flogging it.

I clearly understand Pobst' need for more power. When a chassis feels good it always feels like you can make use of more.
Interestingly though this car get's smashed in the mouth at Road Atlanta by current well driven C5Z06 Race Cars even with Pobst at the wheel of the C7Z06. You don't have to spend even half the money of the new Z06 to go as fast or faster as long as you can drive.

I guess they are talking about the A8 above!
But!
This is a great sign: Its 22.5-second lap on the figure eight is the second-fastest production car we've tested behind the Porsche 918's 22.2 seconds; the Z06's 1.16 average lateral g is the highest we've seen from anything that wasn't a race car.
A heavy freaking RWD car doing this stuff!!!

I am just kidding!!It's a super cool car but most street cars are typically junk without mods in a roadcourse environment. Well prepared and well driven race cars go around them like they aren't even on for just a single lap and they can do it for the length of an entire race. The jury is definitely out as to whether or not this new car is up to the task of 3 day track events. We will see soon enough and I can't wait to run against them. Next season is going to be lot's of fun!!

For us it will be interesting to see how this plays out in actual track environments and what modifications are going to be required to make them reliable and able to maintain a high level of performance lap after lap. When they get hot my guess is they will pull timing reducing power output and lap times will slow.

with all the comfort of new C7 Z06 ?
stripped down rebuilt race cars with slicks..... compared to a street friendly , street legal comfortable street/track toy ? not fair... u think ?

You can't compare full race car times to a street car. I know both of those guys and race with them. Those cars, like mine, are gutted full race cars down to about 3100 lbs with driver and full aero. More importantly they're on full race tires, which make a MASSIVE difference. The C7Z < 1:30 time is amazing on street tires. Especially in a car I could daily and drive across country whenever I wanted. It's very disappointing that this thing seems to be good only for a few hard laps before it gets hot.

Turn 12!
The Auto is old news, but, excessive heat soak is hot off the presses!?

Not heat soak... the MT article stated Probst got a "High oil temp" warning; assuming engine oil. Also, the car looks like a dog on the top end in the videos. Only hitting low 150s is horrible for a 650 horse car. My 385 rwhp aero'd race car hits 150 out there. I guess the thing pulls timing, heat soaks, and/or that rear spoiler has tons of drag vs. a proper wing.

I just was looking at a MT video!

While the automatic makes the Z06 the faster car, limited vehicle availability meant we could only run performance tests on a manual

Yeah it appears the yellow was manual and white was auto. The guy going sub 1:30 in the auto is astounding. It's astounding in any street-tired car, but being an auto is even crazier.

Good points... just watched the MT video... may be some hope yet as Probst was flogging the A8 for the hot laps. No mention of overheating the MN7 car and no specification on which "oil" got hot.
