Click above for a high-res gallery of the Nissan GT-R

As expected, Nissan has responded to Porsche's claims that the GT-R isn't quite as fast as they say it is. In fact, representatives for the German automaker suggested that Nissan may have used racing slicks to achieve the 7:29:03 lap time of the Nürburgring. Says Nissan, "The final word from us is that it was done on absolutely standard tires which are available to customers in the showroom. They're not trick tires – absolutely standard tires, normal road tires."

Despite the allegations, Nissan is remaining calm about the issue, adding that the fast time was set by its racing driver, Tochio Suzuki, and achieved using the GT-R's optional Dunlop tires. Could it be that Porsche purchased a model with the slightly slower Bridgestones? Maybe, but can having the right tires could account for a 25-second lap time difference? In any case, Nissan's taking the high-road, falling short of suggesting that Porsche's drivers are slow. Thanks for the tip, Ed!

      I think it's great that Nissan built the GTR and it can compete with the 911 Turbo, a car double its price. But Nissan's marketing and direct comparison to the 911 Turbo isn't to steal 911 sales, but rather sales of cars closer to its price range, such as the M3, S5, CLK, etc.

      I saw a mention of the NSX, which is perfect. The NSX was built to compete with Ferraris of the day for half the price, which it did. The NSX wasn't built to steal sales from Ferrari, however. Mainly to prove that performance can be attained for less. Many people buy Ferraris because they're Ferraris. Many people buy Porsches because they're Porsches.

      Folks Porsche know something or they wouldn't have given Nissan the lip. Expect to hear more from Porsche on this, they will eventually embarrass Nissan, hide and watch.

        How will they de-embarass themselves?

      well done Nissan

      Missing an important factor here, Porsche stated that they had one of their development engineers make that laptime, not their official Porsche test driver Rohrl. Hardly an adequate driver to push the driving potential of the GT-R.

      No other manufacturer is disputing Nissan’s claims. Porch should stop sulking an finally realise their ancient design is past it’s sell by date.

      The GTR is probably by far the MOST overrated car in the history of the automobile, hands down.
      It has SO much hype from both the press & playstation-playing teens that they are selling one a couple blocks away from my house at a Nissan stealership for $50,000 Markup!!! On a $76,000 car!? How do you justify that?

      First let me say, one non-race compound tire to another(of which both are considered high performance) isn't going to make a 25 second difference at the Nurburgring.
      You fanboys think the GTR emits magic fairy dust out of the exhaust. How can a car that has the same flywheel HP, 75lb ft less TQ, weigh 406lbs more, and trap 5mph less on the 1/4 mile, yet has the ability to best it by 25 seconds on the fastest(highspeed) track in world? It doesn't make sense.
      I mean, correct me if i'm wrong, but it was beat by the ZR1 by ONLY 3 seconds!?
      It has 158 more HP, 174lb ft more tq, weighs 575lbs less, only manage a 3 second gap? It just doesn't make sense. There is no magic involved. Nissan's #'s just don't add up.
      I'm with Porsche all the way. Everyone is just upset because someone over at Porsche finally had the balls to come out and call BS on Nissan.
      I think it's time for Nissan's product people to put their PS3 controllers down, call up Porsche, and organize a little race over in Germany.

        When someone comes in with $126,000 and says I want that car in the window!!! That's justification, fanboi.

        911s are good for one thing, drag racing. That engine sitting out back gets you a good launch off the line and then it's ALL LIABILITY, ALL THE TIME. They go around corners like a sack of potatoes in a shopping trolley. DEAL WITH IT.

      Don't forget that they used a US-spec version which is limited to 156 (and no GPS like the j-spec to increase the limit). How much do you think that would slow it down on the longer straights? 25 seconds worth? Quite likely.
        • 6 Years Ago
        First off, Porsche's not going to do something stupid like that - Their own cars are limited, and if they're going to take one set of limiters off, they may as well take off the others.

        Second, note that the Nissan PR crew has said nothing about the engine being stock, or running stock boost - This is the area where most of us suspect the GT-R's performance numbers come from. Again, compare the ZR-1 and the GT-R on the straights - The GT-R matches the ZR-1 foot for foot, even though the ZR-1 should have an extra 160 horsepower and 500 fewer pounds. The GT-R's all-wheel-drive won't help it accelerate much at speeds greater than 70 miles an hour, and most of the corners at the ring are safely above that.

        Finally, If C/D has found that the press GT-R was running more boost than the actual production cars, what makes you think they didn't jack the boost through the roof for the last lap on the ring? IIRC, the GT-R was reporting times at most in the high 7:30's up until the record-setting lap, when it suddenly drops 10 seconds. From my racing experience, you don't make those kinds of gains suddenly after several months of testing, not unless you've been weighing the car down with lead bricks. If you try and tell me that Nissan has been overweighting a development car, on a track for which the sole purpose of establishing an engineering team is usually to fine-tune suspension settings, I suspect you are not quite qualified to participate in this discussion.

        With regards to the ZR1 and GTR having similar straight line speeds, I believe it was reported that there was a stiff headwind when the ZR1 ran.

        Regarding the 7:38 vs 7:29 times for the GTR, the 7:38 was run during non-optimal conditions. The drivers reported that a few corners were wet and knew they could go faster. Sure enough, they went faster.

        You say that Porsche would remove the limiters. Nissan themselves has said that removing the limiters on the GT-R are difficult, leaning towards impossible, for non Nissan people. I doubt Porsche threw a ton of money in trying to remove a limiter for something as minor as this test. Also, the referenced C/D article showed that it wasn't a ponied up press car. They had two that tested below, and two more that tested right in line with the press car. These 4 were customer cars. They said it's the best performance bang for your buck, and they said that it appears they really are creating more than the official HP.

      "standard tires available to customers in the showroom" That sounds like political speak to me.

      Now if they said "The same exact tire that comes on every GTR out of the Nissan factory to your showroom floor" I would be more convinced.
        • 6 Years Ago
        No you wouldn't you obviously don't want to be convinced.

      It does seem a little petty to do what Porsche is doing, but there have been more than a couple accusations with people not being able to come close to the times Nissan is claiming the car can put down. I mean on a race track 25 seconds is just absolutely massive and I could certainly see how that could raise some serious suspicions. It really isn't unheard of either for car manufacturers to give journalists "special" cars to help generate publicity.

      I drove both at the ring on the Gran Tourismo. Porsche wins!.

      OK, all of 911 haters or rear engine haters better go suck your thumb some where as I am going to hit you with a fact: 911 based racers are the most successful in racing history and have an unmatched history. I will start you with a few OVERALL victories that no other model (or manufacturer for that matter) can claim: LeMans (935), Daytona (935,GT3,911RS), Monte Carlo Rally (911R), Sebring (935), Paris Dakar (959). So in summation, the car that owns the best competition record in history are based on the Porsche 911 and are all rear engined. The rest of the Ring argument is all BS, no factors seem to have been controlled for making all times released by anyone suspect at best. Anyway, I seriously doubt I will ever be able to drive on the Ring in any car as neat as the 911, GTR or ZR1, so this is all bench racing anyway.

      Every article i've ever read that compared the GTR to the Zo6, put the nissan slightly ahead, usually between 1 and 3 seconds per lap, regardless of the distance of the track. Which includes, this months lightning lap at virginia, where the nissan cranked out a 2.56 (very good) and the zo6 last year ran a 2.58. And that's on what's basically a 3 minute lap track.

      Now on a track as wide open as the ring, nissan claims to be 14 seconds faster than the Zo6.
      I'd almost say for sure, the vette is faster in the straights, based on power to weight and likely aerodynamics.
      Lets just say for arguments sake, that we can double the nissans lead from what it did in virginia.

      Still, where the hell did the other 10 seconds of the lead come from?

      Nissan, invite the press out to witness the run and examine the car.
      That will end all of this. Although we all know it won't happen.
      But i'll sure as hell bet that if GM was accused of cheating, they'd break the car out and prove it.
      That's the same reason they didn't bother to accuse GM of anything.
