The new Nissan GT-R is already a modern day classic, a statement proven by the fact that Nissan UK received 700 orders in just 48 hours when they opened their order books. Nissan UK is trying to convince Nissan HQ to allocate more units to the British Isles, but since Nissan can only (hand) build 1,000 engines per month it seems unlikely that the request will be granted.

In the meantime, Nissan has quietly shipped a light-weight and heavy hitting GT-R V-Spec to the Nurburgring for testing. Where the regular GT-R boasts 480 hp, this turbocharged V-Spec should see at least 550 hp and is capable of a 7:25 Nurburgring laptime, 18 seconds faster than the GT-R.

The Nissan GT-R V-Spec prototype features a revised front splitter, additional air intake slits (presumably for extra brake cooling), new six-spoke wheels and what seems to be a new braking system. Upon closer inspection of the brakes, our spy photographer thinks that a carbon-ceramic brake set-up seems most likely.

We expect that the Nissan GT-R V-Spec will be shedding 150kg in comparison to the GT-R, not exactly in the featherweight class, through the use of various carbon fibre body panels and weight saving technologies. For one, the rear wing is taped up on this prototype leading us to believe that this is one of the carbon-fibre components.

I don't know who gave this time to the car, If It was Nissan Itself or someone measuring at the time, but I doubt that..since the Carrera GT did It In 7:28, which has more outright power and also power to weight ratio, lower centre of gravity, and lower weight.

toffytofik 04-09-2008 09:53 AM

Apparently the time was measured by the spy shooters, anyway that's just rumors. Nissan didn't claim anything yet. They just began testing it, experimenting with the set-up.

madpony 04-09-2008 10:39 AM

The normal GTR has worse power to weight ratio than all the cars it beat around the ring as well. It's a cornering car.

04RCSTI 04-09-2008 04:58 PM

I told you all this was coming..

styla21 04-09-2008 10:24 PM

The car looks great - and I love seeing weight-reduction being used as a feature in refining a sportscar. It is a true, and real performance addition (subtraction?), not some fancy marketing gimmick (carbon mirrors aside..). :thumbup:

But, I cannot accept that the V-spec will do a 7:25 lap time. It's physics defying, and on a comparable analysis to cars in that performance band, just cannot be compared (or justified).

Afterall though, it's not as if the opinions of some blazee photographers quantify factual timing. :-)

does anyone have a table of 'Ring record times for production cars?

Once it got off shaved race tires it didnt.

Just let them have their fun.... all the while you pass them on the track, and on the street ;)

I bet the GT-R badge provide extra aerodynamic efficiency and extra power. More importantly, it also provide anti gravity to counter it's own weight.

Those of us with the Sony Europe copies of GT5 Prologue, now have the GT-R Story HD movies in english (the Japanese copy of the game has Japanese HD movies :P) - and includes Nurburgring laps etc.

Hopefully they will appear in HD on MW soon so everyone can enjoy them.

I was really surprised at how slow the GT-R sounds and looks, even though it is going quite quickly, maybe the badges do allow it to defy the laws of physics in our dimension ;)

This is by far the most popular argument used to explain GTR' quickness. RE07R Potenzas aren't race tires.

madpony 04-10-2008 11:54 AM

*Someone posts more numbers/articles/reviews/tests of the GTR*

"OMG NO WAI CONSPIRACY. PHYSICS, PHYSICS, PHYSICS! STICKY TIRES. ALL CAR PERFORMANCE IS ON A LINEAR PROGRESSION WITH ALL OTHER CARS AND PLATFORMS BASED ON POWER/WEIGHT RATIO."

No they are not - but the superquick time was set with cut slicks - Nissan test team admitted as such already.

Reasoning. If you can't get past that, I don't know what to say. These lap times weren't verified or replicated by independent testers. Besides, we've been correct so far, as the GT-R makes whole lot more power than claimed.

The GT-R cannot bend the rules of physics. It's not a miracle car that somehow gets an exemption from common sense. But as we can clearly see, Nissan can lie about the car to make it look better. ;-)




Until Nissan officially makes the claim about the GT-R V-Spec lap times, I say hold your breath. Although, I can't trust Nissan anymore, and they just might use this particular lap time they just found on the web.

Every single lap (including the best lap of 7:38) was done with stock car on stock tires (Bridgestone Potenza RE070R RFT) and Nissan never confirmed otherwise. AFAIK, rumor that car was running "cut slicks" was started by PistonHeads and proven to be false later on.

The tires used in the video shown were not the same tread pattern as what the car has in stock trim ;)

Several interviews were performed where Nissan admired to using "cut slicks" ;) No rumors, retractions, or falsehoods ;)

A word from the journalist who was on the track while Nissan tested the car:
Quote:

There's been some confusion over the tires used on the GT-R during its 7:38 lap of the Nurburgring. Various sources have reported that cut slicks were used. This is incorrect, and stems from a language barrier at a press conference during the GT-R's debut at the Tokyo Motor Show.

Senior GT-R development engineering staff on hand at the 'ring trip I attended confirmed that production-specification (including the tread compound) Bridestone RE070 tires were used on the 7:38 lap.

The three pre-production cars Nissan had on hand during the final Nurburgring trip were production-intent configuration. The strongest car of the three (within production variation) was selected to run the lap, with no "hotting up" done to fudge the result.

PistonHeads translated Mizuno's quote as:
Quote:

'We used cut slick tyres' said Mizuno.

http://www.pistonheads.com/gassing/t...?f=23&t=455380
While he was talking about possible time on the dry track:
Quote:

Mizuno claimed a time of 7minutes 38 seconds, compared with 7:43 for a Porsche 911 GT3 and 7:32 for a Carrera GT, but he was anxious to point out that there had been “two wet patches on the circuit.” Indeed, he mentioned the “wet patches” so many times that you wondered why Nissan simply hadn’t waited for a dry day. Mizuno reckoned that a time of around 7:30 should have been possible in the dry, but that going much faster would have required hand-cut slicks, which isn’t “real world.”

You do know the you tube is a copy of an hd one right? Its quite obvious they are cut slick tires from the video, not to mention the nissan quote which is starting to sound like something out of hillarys mouth.

Seriously.. Why was auto sports time so much slower? Their both claimed in the wet afterall? Slower then the z06? and more in line with what wed expect. Is autosport paid by gm.. come on now.
Not to mention weve already seen data showing the z06 with way better acceleration and miniscule difference in grip.. on run flats.

79TA 04-11-2008 02:37 AM

Yes, magazines who use the same test driver for the ring have gotten other cars much much closer to their fastest lap time while the GT-R's 7:38 seems to have been a one time feat.

To be fair though, I'm not familiar with other testers replicating times of either the GT2 or Z06.

Sport Auto is usually about 6-8 seconds off factory times.....

Finally looked up some other test numbers for myself. Yea, the GT-R's numbers have a much larger discrepency.

Blimey! :banghead:

Sportauto with the famous driver Horst has driven the new Skyline on N-ring.

*7:50 --- 157.787 km/h -- Nissan GT-R, 480 PS/1750 kg, Horst von Saurma, partially wet track (sport auto 12/07)*

Horst von Saurma, chief editor of sport auto magazine, completed about 100 kms with the new Nissan GT-R at the Nurburgring Nordschleife. Best time he achieved was a 7:50 on a partiallly wet track especially at one of the key passages so called Kesselchen.

With all the electronic aids the handling is absolutely perfect, the driver doens´t feel how the drive-by-wire system really works as the GT-R stay on track like on rails, always has grip, doesn´t lose control, higly computerized and a perfect racer for the street. A time less than 7:40 is pretty much optimistic, 7:50 shows the true potential of the car. And when the price stays at the announced level, it is a real bargain.

Sport Auto lap time comparisons:
Ferrari F430 F1: 7:55 seconds
Ferrari 599 GTB Fiorano: 7:47 seconds
Porsche 997 911 Turbo : 7:54 seconds
Chevrolet Corvette C6 Z06: 7:49 seconds
Ford GT:7:52 seconds
Nissan GTR: 7:50 seconds

""Also it SHOULD be noted that the 7:50 Sport Auto recently got with the GTR was a Fahrberichte. This means they they are test driving it around the ring to describe more what the car feels like and their impressions of the car. Not to set a fast lap time. The important result will come when they do their Supertest."".

The "supertest" is when they actually take the car out and try to get the fastest time they can. They won't do it until the GT-R is on sale.

aaaargh these lap times are driving me crazy :tard:

RC45 04-12-2008 10:38 AM

doesnt matter anyway, the proof will be on the street, drag strips and road courses as owners and enthusiasts ue their car.

How it performs there is what counts - regardless of magazine penile-extension tests.

:)

Some will fear the DudZilla with nitrogen filled tyres - the rest of us will chuckle to ourselves quietly....

"Silly Lizard, Trix are for kids....." :twisted:

Bring it on... :laugh:

I do believe you hit the nail on the head with a quote and were completely oblivious to it.
They are waiting till the car is on sale..
I repeat:
They are waiting for the car to go on sale.

Now do tell us why they would do a thing like that and what that says about the car they drove.....


The reality is, even the other track tests from other sources do not reflect such a lap time from the gtr. It loses in acceleration in a range that happens often on that track. Its also behind on straights and long sweepers. Again not looking good.

The telemetry data from the fixed rand t test where they used a nissan test driver who owns a nissan shop even showed the z06 equal or better then the gtr in all but 2 corners. That should be a red flag.
