Honestly I dunno.

I just know that Pobst's car in that R&T video overheated after 4 laps at Road Atlanta. His car was an 8AT.

Also aren't you curious why there was no commentary fro Pobst after his test drive? Usually there's almost always some feedback by Randy. Not this time. Odd, no?

GM still hasn't figured out the overheating issue with that transmission which is why ALL current production Z06s are in 7MT guise. Look around dealer inventory and there's only the 7MT available. I don't think dealers can even guarantee a delivery date for the 8AT even for customers who have put down a deposit and ordered an automatic.

car and driver just tested the z06 w/z07 package. acceleration figures were about identical to the gt3, except it was a little slower to 60 than the gt3.

so much for having an extra 175 hp and double the torque.

And lower top speed

C7 Z06: 186 mph
991 GT3: 195 mph

So much for all horsepower.

I wouldn't call it a scandal as it's really the norm of most cars marketed as race proven etc with a heavy track spin. Very few cars are suited to track duty beyond 3-4 hot laps. Getting to 4 laps with a driver of Randy's ability is actually pretty good

In fairness to the Z06, it's going to have a hard time putting the power down at low speed due to being RWD but front engine. From say 60 to 120 mph, I suspect that accel of Z06 will clobber the GT3.

I still think it's a great looking car, but given the choice between a 458S and a GT3 RS + dedicated track car, I picked the latter.
Exactly. Which is why I have kept my 458 and didn't try to get a special. On the street I would rather have an italia anyway.

I think you have to consider the GT3 in it's own light.

Would you be ok if the same thing happened to the GT3?

well it also trapped 126 for 1/4 mile, same as the gt3.

... because of the inability of the Z06 to put power down at low speed. And let's keep in mind that these are supposed to be track cars, not drag racers, and accel from 0 to 60 is of limited importance at the track.

This is zero surprise to me. The z/28 and prior z06 does the same. A magazine article documented that and I have video of one that barely pulls a boxster on the straight. A friend of mine who is an engineer for Chrysler says GM is notorious for not addressing cooling issues.

This is probably why there is no ring time and why the z/28 time was done in the rain

I have different expectations on a GT3 - it's that reputation that keeps people coming back to the brand. My track days are not club days, but any car is allowed, you see probably 60% pcars, 20% Fcars and a smattering of others here and there, with Lotus probably being the next most common.

The guys running 650S, Audi R8s etc all face major problems with brake fade, overheating, oil consumption etc. People should do their research before buying a car based on magazine and media hype.

trap speeds are indicative of horsepower. Actual 1/4 time is a factor of traction AND hp. Trap speed is a good indication of what kind of power the car is making regardless of traction

this says how good the 458 really is.
