Just yesterday, it was reported that the Nissan GT-R lapped the Nurburgring faster than the Porsche 911 Turbo with an unofficial record time of 7:38. Earlier this morning, Nissan engineers took the GT-R at the Nurburgring circuit once again for high-speed testing and set yet another record (unofficially).

New reports from the KGP spies say that Nissan engineers hinted that the GT-R lapped the Nurburgring somewhere under 7:35. With a time like that, the Nissan GT-R is setting its sight on the Carrera GT. Walter Röhrl has reportedly lapped the Nurburgring in a Carrera GT in 7:28. Another Carrera GT run, by Horst von Saurma, was clocked in at 7:32.

as a reference, z06 did a best of 7:42, 4 seconds is alot.

I will stick with what I said earlier about this...

http://www.thscc.com/phpBB/viewtopic.php?t=6470

Given equal rubber, drivers and with the cars at stock HP (no ringers) the Skyline is not going to beat the Carrera GT.

I am not trying to downplay the capabilities of the Skyline as even with a ringer engine and tires the pucker factor would be off the chart to run times like that. But in my VASTE experience in driving the Nordschleife (via various simulation style racing games :oops: :wink: ) I can say that with the given assumption of a modern suspension and skillful driver, quick lap times are generated by…

* Power
* Power
* Power
* Tires

Even a high power to weight ratio is not going to guarantee quick times. The long runs uphill from Bergwerk to just short of Karussell, Dottinger Hohe to Hohenrain-Schikane and Hocheichen to Adenauer Forst requires power to go fast. I would guess that those sections when added together would take up nearly ½ of the distance of the track. With adequate power (which the cars we are talking about have) the rest is down to suspension setup, driver ability and good tires. So if you have a turbo car in which you can just keep turning up the boost... It is impressive for the engine technology, but is less impressive when compared to NA cars.

I am sure these are not available, but I would be more interested in seeing for the following.

Section times for…

* Metzgesfeld to Bergwerk (tricky downhill run to Bergwerk with odd camber turns. Mix of fast and slow speed turns)
* Karussell to Dottinger Hohe (mix of slow to medium speed technical and higher speed sections over rougher section of track)

Speed trap (top speed for)...

* Fuchsrohre (how fast can you manage during the downhill run toward Adenauer Forst)
* Angstkurve (measure of how fast you are going uphill toward Karussell as well as a measure of how quick you can take this high speed decreasing radius turn)
* Burgwerk (medium speed turn that sets you up for the uphill climb)
* Antoniusbuche (what is your terminal speed after the long straight that started at Dottinger Hohe)

Richard

PS: I WILL drive the Nordschleife for real some day. 8)

We will have more details on this in the next few days at the product launch. Maybe they will have more of the ring's run information.

Then add to that debate the cost of the cars being compared. Full out fastest car is all well and good. But if a $30K car is 2-4 seconds slower on a 7:30 minute run than a $150K car. Well... there is something to be said about that.

The CGT listed for $440k. I'm sure the Skyline will be well north of $50k. Comparison is still valid, just helping you with the numbers.

Not well north, but North.

Starting is $60K, top of the line is $72K.

I had no idea how much each car cost. I was just throwing out numbers. Thanks for the clarification on just how obscenely different the prices are Donnie. :wink: Now that's not to say I wouldn't take the CGT over the Skyline if I was being offered one for free...

I know doing the ring is bragging rights and all. I just love to see the cost of the vehicles being compared. Puts it into perspective just how much money some companies have to spend to be competitive.

Not to nitpick, but $10k more is "well north" of $50k when you're talking about *those* kinds of numbers. In my mind, 20% == "well north", anyway. Saying "north" only would mean something more like $55k or so.

I'm just sayin'... 8)

I'd also bet dollars to donuts that the Skyline that lapped that fast wasn't one you could buy for $72k or at all. Like Richard said, it at least had something special in the tire department, and I'd bet it was way more than that...

Now that we've asertained that Nissan cheated and preped the skyline for the run. Lets get the scoop on what Porshe did to the carrera when it made its attempt at the record. Is anyone Naive enough to believe that that car was not preped to the nines for the run???? Get real, Nissan and every other manufacturer is doing the same thing when it comes to setting records. You may not be able to buy the skyline that ran the ring but you won't be able to buy the CGT or the Z06 that ran it either or the radical or any of the record setting cars. I don't see how you can talk about equal rubber, drivers and stock hp when one car costs 72K and the other 400K. Its patently obvious, to everyone except die hard porshe fans, that if Nissan wanted to compete in the 400,000 dollar market they'd kick the shit out of Porshe, they're almost there now with an auto of much less cost.

My favorite was BMW's X5 LeMans that Hans Stuck ran a 7:49 in - aluminum body, 700+HP V12, 311kmh on the straight :shock:

I don't see how you can talk about equal rubber, drivers and stock hp when one car costs 72K and the other 400K.

As far as I know there is no official keeper of track records at Nurburgring. If there was, it would only be those generated during sanctioned races in which cars fit into classes, etc. So obviously anyone can show up and do what they want and beat their chest and claim to be king of the hill. For example the recent record set by a Radical as the fastest street legal car. Technically correct, but we all know the Radical is far from a true street car (still would love to have one).

Here is a decent list of lap times...

http://en.wikipedia.org/wiki/Nordschlei ... _lap_times

This includes the Skyline time. And as I mention above, the times for street cars is pretty much the honor system.

Could Porsche be showing up with a ringer? Sure. But I am guessing that they have little reason to do so especially since they don't have a history of inflating performance figures for their cars. Also, does Porsche need to go and prove anything to Nissan? No. Nissan apprently is using the Porsche 911 turbo as it's benchmark. I think that says a lot by itself and may explain why Porsche may not feel the need to "cheat".

Regarding the Carerra GT, I am sure Porsche setup the suspension (alignment, ride height) and probably have good tires on the car, but not race rubber. I would be suprised if they did have a ringer engine. If they try to load the deck at all it probably is via driver selection. Which for them is a no brainer as they have a number of good drivers they have close relationships with (or are on the payroll).

The 7:28 time that is listed for the Carerra GT is not the only time for that car. There is also a 7:32 time listed by different driver. I can easily see a four second lap difference being attributed to conditions, driver, etc. Someone (most likely a European car magazine) is going to buy a Skyline and see what it will do on the Nurburgring. Its not like any of this is a big deal or related to world peace :) but the truth will come out after the car is released and then we will see what the true times are.

Sign me up as a die hard Porsche fan! But I am puzzled about the "kick the shit out of Porsche" comment. There truly is nothing to back up that comment at all. If we want to talk about true super cars, then let Nissan bring one to the market and then we can talk. Otherwise what you are saying is pure speculation.

What Nissan is doing is apparently building an excellent sub-100k car. And what we are really talking about is how well a 100K car is doing when compared to a 400k car (which is a legitimate comparison.) But if you graph lap times to car cost, you are going to see a "knee" on that curve. Above that knee you are seeing diminishing returns when it comes to spending money to drop lap times. Or the car becomes less and less a “street car” (i.e. Radical and the Donkervoort) I haven’t drawn the graph, but my guess that the real sweet spot (bang for the buck) is for those street cars doing around 7:40-7:50 (911 GT3, 911 Turbo, Corvette Z06, etc). And again, I am guessing that this is where the Skyline will end up, but not in the sub 7:30 territory. Frankly any large automotive company could one-up the other if they wanted. It is just a function of how much money they want to spend to develop the car and how important the image of that car is to them. I can understand why the image of the Skyline is important to Nissan.

If you want to talk about Porsche getting their ass handed to them. The lets talk about how the motorsports division continue to insist that the 911 is the right platform for GT racing vs. building something like a GT version of the Cayman to compete against Ferrari.

The "ringer" thing in Porsche is the driver that they are using for the Nurburgring time: Walther Rohrl he is not young anymore but he is a hell of driver, ex. Rally champion etc. If the newer Porsche are handling that well is partly because of him as one of the test driver.

Having driven the ring a few times, power as lot to say regarding lap time, the uphill section are a killer if you don't have power. You just put your foot to the floor and wait. I would love do it in fast car, my car will be fun but I'm sure the uphill section will still be long.

From the wikipedia entry:

"10:08 - Ford Transit driven by Sabine Schmitz for an episode of Top Gear (Series 6, episode 7; Bridge to Gantry within tourist traffic) "

Anyone who didn't see that episode, check it out, it's hilarious.

That episode is great. I wish there was an unedited version of the in car/truck view for the entire lap.
