ZR1 Chief Engineer: "GT-R won't be king of the ring for long"

[1SICKLEX]

The Nissan GT-R's 7:29 lap record won't stand for long if Chevrolet has anything to say about it. Speaking with InsideLine, Corvette Chief Engineer, Tadge Jeuchter, says that the ZR1, "will be able to take the production-car track record at any racetrack," and that although Chevy doesn't have a production version of the uber-Vette at the Nurburgring yet, they're expecting a lap time of "seven minutes, twenty-something seconds." That sounds like smack-talk to us. But while the ZR1 might have the potential to best the GT-R's 'Ring time, the 550-600 hp elephant in the room is the forthcoming GT-R V-Spec, which is already putting down (roughly-timed) laps around the North Loop in the 7:25 realm. Let the battle begin. We're making popcorn now.

[Captain-Obvious™]

yeah but how much is that vette gonna run somebody? vs the cost of the gt-r?

[Batlground]

It doesn't matter how much it cost. If you put a Z06 on the same tires that are on the GTR it would run faster lap times than the GTR

[_Christian_]

ZR1>GT-R

[blackshine007]

100k for the uber-vette, I think possibly 90k for the V spec.

[Mr. Clean]

i love imports but i'd rather buy the vette for the price....:2cents:

Well this is the tire setup that the GT-R ran those #'s on, nothing special

BRIDGESTONE POTENZA RE070R

Tire Front 255/40ZRF20 +45
Tire Rear 285/35ZRF20 +25

the GTR puts power down to the ground tentimes better than the corvette.i dont care i its the zr1 or what. with the vspec coming out, Nissan is aiming at breaking the ring record. chevy can suck it.

[1.8t]

What he is saying is that the Goodyear developed runflats absolutely suck ****ing balls....which they do. They don't have near the development that the Bridgestones have. My "supercar" tires on my Z51 package suck as well. They are something like a 120 treadwear rating but honestly feel like they have the grip of a 250 tread wear or so. I will put it this way, BFG KDW II's are an upgrade with regard to traction. They are a great tire, but they shouldn't be able to outperform a max performance summer tire. Stock runflats should perform on the level of BFG KD's and they aren't even in the same league.

such a fanboi. lol

[cdhtang]

americans car manufactures/tuners to bring their cars to taksuba, not only to Nurburgring, see what's their lap time.

[Thighs]

i couldve told you that the vette would destroy the gtr. v-spec or not, the vette is going to come out on top.

the vette has more power, weighs less, and has ALOT more torque. the corvette suspension is also ALOT better than the GTR. not just in setup, but in design and the way it distributes the load onto the chassis.

[Vteckidd]

IMO its 2 totally different classes of cars.

I mean its like comparing a C6 z06 to a Ferrari or Porsche.

The GTR is the new Jap SUpercar, the Vette, is , well, still a VETTE. Brute power, great handling, american sports car.

The people buying vettes IMO wont be looking at GTRs and vice versa.

They are two totally different crowds and buyers.

Id personally take the GTR cause i think it looks better.

[Thighs]

^^ true.

but were just talking about which one will be faster. my vote goes to the vette.

[JITB]

im gonna put my money on the gtr..

what tires does the zr1 use? b/c the gtr uses the run flats.. did they use those on the ring?

[man]

the GTR puts power down to the ground tentimes better than the corvette

That's what some of us like to call AWD and lower hp...

My old Camry put its power down 10x better than the GT-R, guess that makes it a better car.

lol X 10, the Vette runs a transverse leaf spring suspension just like the Model T. It's real advanced.

yes Stock JDM tires, and they are run flats

The GTR has my vote. I love the vette, but just like the new technology better.

so if the gtr does beat the zr1, its back to the 911...for the gtr haters...:)

[Bruce Leroy]

:stupid:


If i had to choose.. I would pick the vette

[Alan®]

I think the GTR will still come out on top perhaps regardless of wheter its the V-spec or not. Personally I wouldn't buy a ZR-1 the Z06 looks 10x better in person and in pictures.

No. 124K before dealer markup.

Right. 98% of the people in this world don't have the capability to take a car to its limit and these chassis and drivetrain electronic aids help average drivers look like better then they really are. I was at Road Atlanta and it felt to easy in my STI. I wanted a twitchy car to really drive the car. But that AWD kept me safe and i felt like i had a more likely chance of hitting the mailbox than the wall on turn 10. The simple fact is a Corvette is more of what a raw sports car is. The GT-R is proof that driving aids will make an average driver into a great driver.

Why do you think Ayrton Senna hated all driving aids?


chevy can suck it.

You had a chance, but you proved once again your an idiot.


I am confident that nothing but good things can come from this.

Until the new CAFE regulations hit and it will be 1972 again where hp disappeared.


americans car manufactures/tuners to bring their cars to taksuba, not only to Nurburgring, see what's their lap time.

That's a split case. Nurburgring has a way of simulating every kind of driving environment imaginable. Tsukuba is a flat 1.3 mile circuit best suited for full out race cars with almost no ground clearance. Why do you think a modern F1 car cant go through the Karussel? It's ok as a rough comparison but you don't need to go to japan what you can accomplish at Miller Motorsport Park. No other circuit in the world comes close to the "Ring. Not at that many corners.


IMO its 2 totally different classes of cars.
1. I mean its like comparing a C6 z06 to a Ferrari or Porsche.
2. The GTR is the new Jap SUpercar, the Vette, is , well, still a VETTE. Brute power, great handling, american sports car.
3. The people buying vettes IMO wont be looking at GTRs and vice versa.
4. They are two totally different crowds and buyers.
5. Id personally take the GTR cause i think it looks better.

Hitting your points in order.

1. You can compare them. They have been going against each other for 50 years.

2. GTR. The first REAL attempt from Japan at making a WORLD CLASS SUPERCAR!.
Vette = Americas sports cars that was brought up from an upside down bathtub to be a race winning GT car. (Starting in 1960 to todays P&M Cars) Even to the rest of the world, they know what a Vette is because it is our sports car and it will always be. I always say anyone that considers the Vette and Shelby Cobra a Muscle car is wrong.

3&4. You would think, but lets face it, Most of the people that can afford those cars, can't appreciate them like us and just see them as status symbols. Look at the Rappers putting 20" rims on Ferraris. They just don't get it, but because of them........Ferrari, Lamborghini, and Maserati are very profitable and are selling more cars then they have ever before. April 08 finished with 5/31 major auto manu having a succesful month (Subaru, Mazda, Nissan, Mini, and Jaguar cause of the XF selling more than all the other models combined.) Companies like Audi, Nissan, Chevy, Ford (GT), BMW (yet to come) and other realizing that there is a definete market for high end cars and approving production of these "supercars". Either way, we win in the end because even if they become used, we have a chance to own a great car.

5. Me too, but cause it's just that great of a car.


im gonna put my money on the gtr..

what tires does the zr1 use? b/c the gtr uses the run flats.. did they use those on the ring?


Rumor says a "zr1" has been seen at the track going around in "about 7:40", these claims are set by track bystanders and have the same value as Spanish F1 journalism. No pix nor confirmed stats exist yet.


so if the gtr does beat the zr1, its back to the 911...for the gtr haters...:)

It irritates me when people who don't understand things outside of the sports compact scene start comparing cars like the Vette, GTR, and 911.

[green91]

I really think the GT-R is going to be able to put down the power more efficiently and will overall take the zr-1.

[josh green]

I think it will get the same review that best motoring and top gear gave the vette. Cheaply made and loose suspension. If it does beat the GTR, im saying its b/c of power/weight.

[EJ25RUN]

i just realized that post took 40+ mins to finish.

Anyone else has something clever to add?

I reread what i wrote. That wasn't directed at you, it was a general statement.

[JITB]

I reread what i wrote. That wasn't directed at you, it was a general statement.

Oh ok, i agree with that statement tho...

I will say this.. without sounding like a fanboy. I dont really see the Zr1 being pushed to beat the gtr's record. In stock form. but i really dont know much on the zr1's suspension upgrade from the z06. i mean an extra 150+hp requires more than a stiffer spring adjustment especially for the ring.

I see it this way, if Chevy went out of there way to make the ZR1 as fast as these insane #'s being made by the GTR. It will lose some of it's true driver aspects. The more electronics, the less fun the car. No matter how fast it is.

Remember the ZR1 gives you a 6-speed with a clutch. Allot of people cant give that up. Why else do all Porsche's give you a 6?

The GTR is like a Pentium Processor......the latest and greatest.

The Vette is like a basic calculator. So simple yet we still use it.

[Thighs]

lol X 10, the Vette runs a transverse leaf spring suspension just like the Model T. It's real advanced.





so your saying that its better to have suspension that pushes up on the fram of the car and causes it to flex than suspension that puts little stress on the frame? ooooookay...

i think if coilovers were better, they would have ran them on the c6r. but they didnt.

and about the tires, the gtr was NOT on stock tires, it was on race tires.

they will be sorta close, but the c6r will be alot faster around the ring. that track is won and lost on the straights, and the c6r has more power and less drag. plus it weighs ~500 lbs less.

I don't know how i missed this.

Lol at really advanced. It was "advanced" in the 60's and then the 70's happened.

[Elbow]

Corvette > GTR all day long

[fight club]

does anyone have the specs on the spec-v?because thats what the arguement was truely about, the zr-1 being promoted as beating any production car and nissan laughing because of the amazing times cut with a regular gtr.

as far as the arguement that the gtr has all the drivers aids, do you think chevy is putting some guy off the street driving the zr1?no. so that has no bearing on the times.

as far as price, the zr1 is said to be 100k from chevy(both motor trend and road and track) and the stock gtr is 68k so expect 80-90k for the spec-v.

all and all, i think the zr1 will have no problem beating the regular gtr around the track. i cant make an opinion on the spec v.

regardless, the new gt2 pwns all.

[FoolsDrifFWD]

good stuff in here

I vote Vette. F all the nay sayers.

as much as you seem to know about this kind of stuff, im surprised by this.

the transevers leaf is a BETTER DESIGN than a coilover. coilovers = chassis flex. thats not a good thing. the leaf spring deflects most of its force onto itself in the center of the car, which causes ALOT less chassis flex. you can brace the shock towers on a coilover car, but thats adding weight, which the leaf already has less of. the leaf spring deflects most of its force onto itself in the center of the car, which causes ALOT less chassis flex.

you have no clue what you are talking about.
They ran stock Bridgestones, watch the first 40sec. of this Nissan Promo video and you can see them on the car.
http://www.youtube.com/watch?v=uGe_fyhQazg
also slick tires don't scream like that, it is the grooves in the tires that make the noise, slicks don't do that.

The Vette is the only car that still runs the transverse setup, the General just likes it that way, just like pushrod V8's. Also with the transverse leaf you can't change spring rates with out removing the whole suspension and it's hard to adjust ride height.

And the Pratt and Miller race cars "the C6-R you spoke of" got rid of the leaf springs and ran coilovers, so that tells you how good it is.

the same amount of pressure is still going to be applied to a point on the vehicle because the same amount of weight is still there.

i meant to say c5r, my bad. lol

and pushrod motors have advantages. for one thing, theres not as much to break. theres also less rotating mass inside the engine.

as far as changing spring rates, your right. but the shocks are where the most adjustment is used, so as long as the springs are keeping the car from rolling too much, its fine.

[green91]

the transverse leaf spring still applies pressure along the subframe assembly thats attached to the body, its still requires reinforcement to the body to handle the additional stress just like is done to the shock towers on a coil over setup.

If that was the case, we would see it in more applications. The biggest problem of a Transverse Leaf is its size and length. Added to that it doesn't allow for as much adjustment. A double wishbone multi link with coils is much more compact. One thing i want to mention as well is that going back to the Oldsmobile TransAm/IMSA cars and the pikes peak pro trucks P&M did, they have always worked with that setup and you typically stick with what you know works. I feel that GM is sticking with transverse leafs for the same reason they are sticking to pushrod v8s and fibergrlass.

I am so happy there is competition between automakers again if finally feels like the late 80s, early 90s again with the RX7, TT 300zx, Cobra, and Supra. Hopefully Mazda and Toyota will catch on. Hoping Mazda will do something with the RX-8.
