edit: the article says the GT-R ran a 1:38 and the ZR1 ran a 1:40... that should read 7:38 and 7:40
I have no doubt that with a track that's not damp, some more tuning, and some more runs, the ZR1 will run a faster time than the GT-R... the question is, though... how much faster. It should run significantly faster than the GT-R for the price.

 

Great video. The ZR1 sounds dayam good. With they had some video of the Camaro test car working the Ring.

 

Too bad the rumor mill says the GT-R VSpec is running 7:25. But then again the original rumors for the base GT-R started with a 7:15.

 

I wish I was a rich man.

 

What would you define as significantly faster? I would think a few seconds (2 or 3) would be pretty good improvement. The Vette should be able to do that, but we won't know for sure for a while.

It's hard to say how hard they were running the car without actually talking with the person doing the driving. So I wouldn't put a lot of weight into the numbers from the shooter. It just ends up being more bench racing.

On another note, Does anyone know if they actually have certified times for the GT-R? I have seen the 7:38 quoted, but doesn't it have to be certified for it to really mean something? Certified might be the wrong word but I know they do something like that.

 

What does a Z06 run on that course?

Z06 = 7:40

 

The GT-R runs a 7:38.5 for 65k, the C6 Z51 runs a 7:59 for ~48k, and the Z06 runs a 7:42.9 for 72k

For 100k I was hoping for a Carrera GT-matching time of 7:28... especially since they've been saying they could take any production car on any track anytime.

 

Truth be told we know almost nothing about the car running including the validity of the times. If a standard Z06 runs 7:42 it should stand to reason that a significantly more powerful and more track tuned ZR1 should be able to shave more than 3 seconds from that time.

 

Definitely... I would be shocked if it doesn't. I'm just saying what I'm hoping for is at least a 7:28... that's also what would be necessary for GM's claims to be true... and that's just on this track.

Keep in mind, though, that the ZR1 is substantially heavier than the Z06, as well.

 

I thought this topic was covered long ago. That was not a stock GT-R, and the times were falsified.

It will, regardless of the price.

 

Was it? Edmunds and Wikipedia seem to have accepted it as truth... what source says they were falsified?

 

The ZR1 may be heavier than the Z06 and base Vette for that matter but 620hp brings down the power/weight ratio to well below the Z06.
5.4lb/hp in the ZR1 and 6.2lb/hp in the Z06. 7.5lb/hp for the 436hp-LS3 Vette.

That's getting close to my CBR600RR ratio and I know how that feels!

With that ratio, more grip and better suspension over the Z06 should mean the ZR1 "should" be quite a bit faster. Like with all racing balance is everything and someone has to actually go out and drive the number.

 

Source? The Nissan engineers and test driver I'll see if can find the article - I may have to dig back a bit to find it. Basically the car was not stock, on race tires, and the car had a rolling start.

 

Probably should wait for some dry track times before everyone gets in an uproar . When the Turbo Cobalt SS was testing , it was running a few tenths off its best of 8.22 on a damp track . Im sure that time for the Z can be improved on .

 

:raises hand:

I think it's the best possible single measure of a vehicle's overall performance capabilities. Run the car enough times with enough different drivers, and the variables go away.
