Heh. As long as the manual transmission exists and sits in the rear with the clutch up front, the clutch changes will be done via automotive proctology.

If you have Creditable facts showing the ZR1 beating the GTR in any competition, 0-60, 1/4 mile, or track, please enlighten us all.

Being a Vette fan, I would Love for the ZR1 to win.
Most races occur in Mexico from a 50-60 roll, and the Nissan would lose. It would have its hands full with a Z06 as well. To most people, that's all that matters....not 0-60 or 1/4 mile. At the end of a 60-150 roll race when the GTR loses, at least he can quote his superior 0-60 and 1/4 mile times.

Well I know of one that gets out in the metroplex in all conditions.

Based on how clean that car is my guess is that it got caught in the snow, not driven in snow.

Maybe if you read the entire post you would see I put down track times also, and GTR won. Even posted a video from Nurburgring, so I guess GTR won at everything.

and your right 1/4 miles aren't important, only whatever you can find ZR1 wins in. oh which is Lateral acceleration.

I hope the ZR1 can beat it, I love the ZR1. But once again, I don't care about your opinion or excuses, I would like to see facts.

look at the tire tracks behind the car in the snow.

I think someone needs to tell all those professional and amatuer racers that thier 1/4 mile track racing is worthless. 1/4 mile is very important for any car that is claiming power. I for one want a car that is fast from a stop to about a 1/4 mile as thats what is mostly done with it when playing around.

All cars are built to hit on a specific group of people. I think the ZR1 is more for the older, conservative people that still want to claim power when they want, and the GT-R is for the ones that are younger and more tech oriented and want to use the power all the time in every day places. Both are great cars and accomplished thier goal of clientel thay wanted. I love my vette but I do give props to Nissan for thier Z cars and GT-R cars. I think the next Z car is going to up there with the new stang as the 370 would beat the older model stangs before the new one came out.

I have mixed feelings on this. I do not want to see the Corvette go the way of Ferrari and be offered only with a puss-o-matic (call it what you wish, the DCT IS an automatic IMO). If it doesn't have a true manual gearbox, I'm not interested. I know the DCT can shift faster, blah blah blah, but I don't care. Don't want.

Although I do believe ZR1 is for all ages and for Performance enthusiasts, BUt it needs to take some points from the GTR, that HP isn't everything, thats why I hope with the C7 they beat the GTR.

Imagine a C7 with corvette HP & styling, and GTR Tech, that would be the ultimate.

I can't wait for DCT, it's the best and best for racing, thats why corvette put it in their race cars. But don't worry they will always offer Manual stick. They will most likely just replace automatic with DCT.

Actually, no they didn't. You're confusing technologies here. Corvette has always had a sequential gear box which is not the same as a DCT. What they were allowed to add this year are paddles for shifting. But the paddles are still driving the same sequential 6-speed transmission. That race car transmission will not find its way into a production vehicle. Way too heavy and too noisy for road use.

I hope GM's DCT is a copy of Ferrari's. That would be super sweet. If the rumors are true; I may buy the ZR1 since it would be extreme nice to drive with out the third pedal getting in the way of driving in any condition.

Comments?
It would be the best thing that ever happened to the Corvette.

Out with the "old" rowing the gears like the stone ages, in with the"new" quicker and faster way of doing things!

one thing I did read about the new GTR is that after 4 hard launches, it will have to cruise for 1.5 miles before it can launch again. I guess they are trying to keep it from getting to heat soaked or something and messing it up. They are very controlling of the GTR from what I hear but its a fast car that I would love to feel on launching. I guess I have to do some NTC rotations and/or a deployment to get me some serious OT (44 OT hrs a week when doing this) and save for the SC.

Yeah your right, I meant to say the Paddles shifting, Got to excited about the technology

I never heard that before, I wonder if that is the version over in Japan, it has quite a few restrictions over their.

My buddy has a C6 twin turbo he did himself, he's pulling 64Rwhp and he can only get 0-60 in 3sec, which is fast as hell mind you, but thats alot of Modding and HP to get .1sec slower than the GTR. I think Chevy needs to work more on down-force, Traction, and maybe AWD. AWD might add some more weight, but look at the GTR, it sure has more pros than cons.

My car has a launch mode only did once. It took off great but know it is a shock to the driveline even if my car doesn't limit it. Guess I should try more. But I am more of a corner fun person that just drag racing from a stand still. I have tracked manual cars and my paddle shift car. I love the paddle shift on the track, right foot gas left foot brake much better control.

And the DCT vs a standard paddles shift single clutch. Well we are talking maybe 0.1 second difference in a 1/4 mile. Is it really that big a deal? Is it worth the complexity of the system for .01 or .02 seconds a shift difference?

I think it's a bigger difference than ".01 or .02 seconds" It's a true Shift not an automatic shifting like whats in the Corvette now. Most people looking to win will take this technology. I don't want any lag in my shifts like they have in the paddle shifters they have now.

Yeah, it looks like the guy gave up and ditched it in a parking lot before calling a tow truck. On the other picture there was dry road behind and a light coating on the grass.

The reason you don't want to drive in the snow these cars is the summer performance tires and low ground clearance. The additional traction the AWD offers in acceleration is useless when you try to slow down and turn. You don't see these cars being driven around safely in snow. And why would you? That's what you have your pickup for.

I still say: DCT yes, AWD no

R u sure its only .1? In my last Audi the difference between the DSG and the manual in the 0 60 was .2 and Im sure the 1/4 mile would be even more as I would still have several shifts to go.
