It looks like they used a surface with relatively poor grip. That would heavily favor the AWD GTR. The GTR really is a great car for launching. I suspect if the test were all cars on a 20 mph roll the results would be much different.

Of course there is the issue that you can't outrun ugly....

GTR are hard as hell to beat. The difference between the GTR and other fast cars is the GTR will run those times consistently. Where as a zr1 will not. They shift so fast and launch so hard it's incredible.

Even on the corvette forums the guys who own zo6/zr1 complain about how fast GTR are and the only way to beat them is on a roll.

not even an audi fan but Id take the r8 with the lambo v10, a gated 6 spd and a drop top

ZR1 has launch control - it should be practically as consistent as any other car. The GT-Rs AWD system does give it a slight edge in consistency (can "always" find grip") but consistency on most of these cars is a moot point since almost all employ launch control. ZR1 is supposedly faster without launch control but of course, the driver has to then be very consistent (not going to happen).

Launch control can't help the fact that the ZR1's drive wheels only support about half of the car's static weight, and only about 2/3 under hard acceleration. The GTR's drive wheels support 100% of its weight under all conditions. HUGE off-the-line acceleration advantage, at least 33%!

Launch control in a rwd car is not the same as the GTR launch control. Like others have said the GTR drives itself. Therefor yes with a professional driver the zr1 is capable of low 11s stock but most of us are not therefor we usually run higher then projected numbers, especially on the street. When a computer is launching the car for you and SHIFTING faster then any human possible it's hard to out run that.

Which is why I said (and I quote):

"The GT-Rs AWD system does give it a slight edge in consistency (can "always" find grip") but consistency on most of these cars is a moot point since almost all employ launch control."

Launch control means that you're getting 95% of the grip available on a consistent basis. In a ZR1, that might make 0.1 or 0.2s difference. In a GT-R, virtually none. That's the advantage.

Secondly, while the GT-R's drive wheels support 100% of its weight at launch, the fact is that the rear tires still have the majority of grip available and they CAN be overloaded (ie, they'll spin) under aggressive launches. The car has enough power and weight shift to still spin its major load-bearing tires at launch. AWD doesn't mean you automatically can put all your power down.

The ZR1 launch control is COMPUTER controlled, just like in the GT-R. The driver only has to shift in the ZR1, whereas (as you pointed out), the GT-R can shift for itself. The ZR1 driver does not have to modulate the throttle when in launch control mode, which means that the only "factor" is shift time, which should be pretty darn consistent for most drivers.

surprised that so few votes for SLS Black. That car is oozes sexiness.

I know what launch control is I have it on my own car but having set set rpm at which the car launches at you still have to feather/slip the clutch just right or you'll spin. In the GTR he dose not have to slip any clutch, he just holds down the gas and goes, no driver error. Also I don't think your really taking into account how fast the GTR really shifts and how much time that shaves off a 1/4. I spend quiet a bit of time on the corvette forums and the guys who own zr1/zo6 always take about GTR. They will tell you how it's very hard for them to beat a GTR unless they catch them on a roll. You can't always speculate when taking drag racing because there's so many variables that come into play.

JonBoy

No, you don't have to feather the clutch in the ZR1. That's why I keep saying it. The car controls power output via the ECU so that you don't have to modulate the clutch. If the tires are slipping, it cuts power rather than force you to feather the clutch in any form or fashion.

Go read about it, then come back and argue about feathering/slipping the clutch in a Vette. It doesn't require it when using the launch control. 0-60 in 3.5s by Jalopnik. It isn't GT-R quick to 60 mph but it's really moving from 2nd gear onward, that's for sure.
