Looking at those figures, the GTR does the sprint in the same time as a 997 turbo, but it is over 100kgs heavier, and makes the same torque but at higher revs. Does that make sense?

[m3gtr]

no it doesnt. thats the bloody point...

you all have to realize that until the launch we are all speculating and wasting oxygen.

for the love of God, cut this out and wait for the launch like all good little boys and girls do.

I don't see, based on what you've just said, why it doesn't.

Tell us why it does then?

You haven't explained why it doesn't make sense to you, so clarifying it is going to be near impossible for me. I don't see where the problem is, and you haven't told anyone where you think a problem is, so any reply I make could be completely irrelevant to your concerns.

So, why doesn't it make sense to you?

Going on the figures presented (not official yet) the GTR is just as quick in a straight line. But is over 100kgs heavier, and doesn't make the same torque as the 997 turbo at the same revs (makes it later in the rev range). Unless it has far superior tyres, and the GTR's aero-dynamics cause half as much drag (joking) I don't see how the 2 could be exactly as quick as eachother in a straight line.

We are essentially comparing apples with apples here. Same top end power, both AWD (not full-time), both turbo etc.

What makes the GTR just as fast with the huge weight disadvantage it has?

I'm amazed that you picked up on the concept of aero, but completely forgot about gearing. If we're talking 0-100 and quarter mile sprints, gearing will play a far more important role than aero when it comes to their times.

Don't forget about the intended market of both vehicles. The GT-R, despite all the guff about it being a "luxury sports car to take it to the 911", still meant to earn that red R and be a road legal race car. That means a relatively close ratio box, to keep the engine on the boil and improve acceleration on the relatively finite-length straight of a race track.

Given that the GT-R is still a Japanese hero car (where most cars are limited to 180km/hr, and you can't legally go that fast on the street) and its biggest market will undoubtedly be the US (where 65mph is still the average highway speed limit) chances are the car will be geared a lot shorter to give better acceleration on the track.

The non GT range of 911s are meant to be road cars, and so in their domestic market (where you can sit at 250km/hr+ on the "freeway") their gearing is going to let their owners just monster people on the 'bahn while not banging off the limiter, as well as beat their speed-limited BMW, Mercedes and Audi competitors when it comes to V-Maxing.

Most of the Euro supercars also like to brag about their 320km/hr+ top speeds and standing kilometre drag times, whereas the US / Japanese ones tend to focus more on the 0-100km/hr & 0-400m times, so once again the gearing required to optimise those times could separate them.

The other thing I can think of is the gearbox. If they're comparing the 997 Turbo against the DSG equipped GT-R, the GT-Rs faster gearchange (and probable launch control) could also overcome the power / weight deficit.

[HotPlates]

I agree. Gearing can play a huge part in launches. Maybe the GTR will have different gear & throttle modes ranging from subtle (city driving) to aggresive (launching), as with Ferrari's and the like.

hey guys you do no the news that 3 GTR's were tested recently at the nurburgring again and they were only 3-4 seconds of the porsche carrera GT, they have demolished the 911 turbo's time and are trying to get the carrera GT now.

[GT-R LM]

"The Nissan GT-R development team has made another run at the Nürburgring record books this morning--and the Porsche 911 Turbo is no longer its target. Sources intimately familiar with Nissan's latest test sessions inform us that the group is now gunning to beat the Porsche Carrera GT--a remarkably lofty goal considering that that Walter Röhrl reportedly piloted a Carrera GT around the 'Ring in 7 minutes 28 seconds. Another Carrera GT, driven by Horst von Saurma, managed a lap time of 7:32.

Our sources tell us that, thus far, the Nissan has fallen short of the Carrera GT's record-time, but not by much. Our mole tells us that some wet sections of the track slowed them down, and that with optimum track conditions, some heroic driving could still reel in the Porsche Supercar. Nissan reps would not divulge any specific lap times, but they hinted that something under 7:35 may have been achieved. Regardless, it's clear that Nissan's goal of overtaking the 911 Turbo has been achieved in a big way.

Stopwatch drama aside, Nissan also gave us some new eye-candy by removing most of the camouflage that has been a staple of GT-R sightings for more than a year now. Although not in showroom shape, the latest GT-R test cars give us our clearest look yet at the prototype's front bumper and headlights, and the GT-R badge is now prominently displayed in the grille-opening, and on the trunk lid. We also managed a pretty revealing interior shot as one GT-R prepared to launch. The rear vinyl camouflage has also been removed, and now only flat-black paint remains to obscure the GT-R's true styling. This is as close as we're likely to get to an undisguised car until the car's Tokyo Show debut.

In their most recent 'Ring runs, Nissan rented the track early Monday morning, and had three GT-R prototypes--spaced one-minute apart--all taking their best shots. One of the GT-Rs was reportedly driven by Horst von Saurma--the same 'Ring specialist that drove the Carrera GT to a 7:32 lap time. Another driver was said to be a Japanese driver named Shimizu--possibly well-known racer Kazuo Shimizu. The third GT-R pilot went un-named.

Nissan will likely continue their assault on the Nürburgring--and on the Porsche legacy--for the rest of this week. If the GT-R manages to do the seemingly impossible and unseat the Carrera GT, we'll let you know."

I read this article a while ago. Unfortunately it's 'hearsay'. We'll have to wait for the official figures.
