I am a mere human and can't remember everything. They don't mention stereo at website though, only AC:

It's still caged stripper on half-slicks, good only for the track.

From 60 mph on the ZO6 is WAY faster and quicker than the GT-R. The GT-R just gets off the line quicker with it's AWD and electronics. Lighter, better aero, and more power is still faster in a straight line....ie. try racing a half mile instead of a quarter mile !!
BTW, isn't it possible to like all these cars without badmouthing the others ??

Lighter and more power, but I don't know about Aero... The top speed of the Z06 is 196mph. The top speed of the GT-R is 193mph. Since the GT-R only has 480hp vs 505hp, I think the aero is pretty well matched.

Aero better on GT-R.

The Aero on the GT-R is better than the C6? I dunno about that one I would have to see the Wind tunnel testing. The top speed of the ZO6 is computer/electronicly limited (I have no idea of the GT-R) and I know that the C5 body has gone 225mph (Lingenfelter prepped of course not stock) and the C6 is more aerodynamic than the C5. Also the ZR1 is supposed to be capable of excess off 200mph no official numbers yet. So all things being equal (according to R&T the performance was allmost identical Track time is suspect if you ask me) I would guess the Aero is in favor of the C6 just look at it. If I'm wrong though I have no problem with it.

BTW what is that in your avatar? An Irish Chihuaua?

GT-R
Drag area: Cd(0.27) x frontal area(25.0 sq ft, est) = 6.8 sq ft

Z06
Drag area, Cd (0.34) x frontal area (22.3 sq ft) = 7.6 sq ft

Top speed is also power, gearing, limiters.

Well, let's ask EVO at Bedford Autodrome:
1:21.7 Nissan GT-R
1:24.45 Corvette Z06

Suspects are everywhere!

Who knows, some photoshopped dog, but I find it hilarious.

Good to see they didn't unuglify it for the US market.

Based on the tests and what not for the GTR straight line speed has the edge going to the Z06.

R&Ts same day test between the 911 Turbo, Z06, and GTR shows this but here is some data from the test.

C6 Z06:

0-30: 1.6
0-60: 3.4
0-100: 8.0
0-120: 10.7
30-120: 9.1 (good indicator of acceleration)

GTR

0-30: 1.1
0-60: 3.4
0-100: 8.6
0-120: 12.7
30-120: 11.6 (good indicator of acceleration)

Based on this information the GTR benefits greatly from having a AWD system however once the Z06 hooks up its lower weight starts to show its advantage. The Z06 goes from 60MPH to 100MPH .6 seconds faster then the GTR infact from 30MPH to 120MPH the Z06 is some 2.5 seconds faster.

Where the GTR on a race track gets its advantage from is its complex computer controlled AWD system along with its transmission gives it an edge. Its able to take full advantage of the laws of physics in spite of its hefty curb weight and less then ideal weight split.

I agree. The GTR is a badass car, but I'd take a ZO6 anyday, all numbers aside it has one thing the GTR will never have....good looks!!!

[chinamonty]

Well looks are a personal thing. I dont particularly like the look of the GTR but to me it looks much nicer than the Z06. As long as you are happy with the car you want why does any one else matter. If the Z06 is point something quicker over a 1/4 mile then good. I seldom if ever drive a 1/4 mile. So if that's your thing good. I dont see why people have to make one better than the other. they are different and different driving styles will get different results out of the same car anyway so comparing apples and oranges and strawberries makes little sense. The important thing to me is that you have choices of this type of vehicle without having to fork over the bikkies needed to get a Ferrari, Maseratti or Aston Martin (all of which have more pleasing designs to my taste).

No it's not. Top speed of the Z06 is NOT artificially limited. It's drag limited. At 196mph in 5th gear, the engine is near redline. The car does not have enough power to reach the same speed in 6th.

It doesn't matter what Lingenfelter did with the C6, becuase at those speeds, it takes a LOT of hp to overcome drag. That's why I said the Aero is pretty much even since it has a top speed of 193mph with less hp than the Z06. Given enough power (assuming there is no limit to the amount of power you can produce), any car can go 200mph. If the GTR had worse Aero than the C6, then given the GT-R has less power, there would be no way in hell it would be able to achieve 193mph.

Are you absolutely certain about that?

I was just saying that if you just go by top speed without knowing how much power the engines make, you can't really make any conclusions about the aerodynamics of the car. A very aerodynamic car may have a top speed of 170mph (for example), and another car that's less aerodynamic may have a top speed of 200 mph... The 170mph car may have 300hp, and the 200mph car may have 800hp, etc, etc. That's why you can't say the Z06 has better aero, based on what Lingenfelter or the ZR1 is capable of. Those cars have significantly more power.

Will you be the one driving the Pacer after we strap on the Pratt & Whitney?
A couple of tie downs and maybe a half-inch grade 8 bolt on the back and you should be good to go.
