I dont know, i was refering the ring thread in the comparison forum. I just checked the link and they said "This overarching do-all philosophy dictated the GT-R's all-wheel-drive system and run-flat tires mounted on 20-inch wheels. Customers will have a choice between Bridgestone Potenza RE070R summer tires and Dunlop all-season rubber."
I believe the ZR1 time, but too bad it looks like it came straight from a pep-boys store i want to see the Pratt & Miller C6RS throw it down at the ring
Porsche has accused Nissan of cheating in the GT-R's record bid at the Nurburgring racetrack. Porsche has just run its own back-to-back tests with the Japanese company's GT-R supercar and says it could not get within 25 seconds of Nissan's claimed record time of seven minutes 29 seconds in April. It also found its 911 Turbo and GT2 were both quicker than the GT-R. "This wonder car with 7:29 could not have been a regular series production car," says August Achleitner, the 911 product chief for Porsche, speaking to the CARSguide at the Australian press preview of the latest 911 Cabrio. "For us, it's not clear how this time is possible. What we can imagine with this Nissan is they used other tyres." He believes the time achieved by Nissan with ex-Formula One driver Toshio Suzuki would only be possible with a semi-slick race-style tyre. Achleitner says Porsche took a standard GT-R, running on regular road tyres, and ran it around the Nurburgring within two hours of its own cars, on the same day with exactly the same weather conditions. He says there was no tweaking of any kind and the GT2 and Turbo both ran on regular Porsche road tyres, the Michelin Sport Cup. "We bought the car in the US. We drove a GT-R with new tyres," he says. Achleitner was initially protective of the exact lap times, which were run during a program when Porsche also compared its upcoming four-door Panamera with a range of potential rivals. But he eventually revealed his team clocked the GT-R at 7 minutes 54 seconds, with the 911 Turbo managing 7:38 and the GT2 getting down to 7:34. The laps were not run by Porsche's usual hot-lap specialist, former world rally champion and race winner Walter Rohrl, but one of the company's chassis development engineers who is an expert on the Nurburgring. Achleitner says the back-to-back comparison was run because Porsche was concerned by Nissan's claims for the GT-R, which is heavier than the 911 with similar power. "The Nissan is a good car. I don't want to make anything bad with my words," he says. "It's a very consistent car. But this car is about 20 kilos heavier than the Turbo . . ." In the end, Porsche believes its testing has achieved the right lap times for the Skyline GT-R and benchmarked it against its own 911 heroes in the right context. "For us it has been clearly the result. This technical puzzle now fits together. With the other numbers we had problems to understand it," he says. - Herald Sun they have my full support!!!
also, as I said in the other thread, "the production GT-R�s top speed is limited to 113 mph, just another proof/hint that they were cheating, with a top speed of 113 mph it never would have achieved that lap time, it was said before that they were using scrubbed tires >>> www.supercars.net/PitLane?viewThread=y&gID=3&fID=0&tID=165119
That also depends on what you call a semi-slick. If you call a Pirelli P Zero Rosso Corsa or a Yokohama AVS Sport a semi-slick, I'll have to agree with you. But if on the other hand you're refering to "regular" slicks with cuttings, I'll have to say no because even with thin layers of water, the cuttings may not be enough to drain away more that 2-3mm of water, specially on very wide tires.
Horst von Saurma-Jeltsch, sport auto chief editor and driving all the cars the Supertest, already drove a few laps with the GT-R (when invited by Nissan) and achieved a 7:55
Yep, that's true. After reading the text, now I say Porsche is bluffing! The GT-R is just 20kg heavier than the 911 Turbo, with the same power, etc. And still, they made N'ring in less 16s than the GT-R??? Now THAT doesn't fit! If they said it could do it 5-6s slower than the Turbo, I'd buy it. But no way that difference is real! I'm not saying they falsed the GT-R time, I'm saying they did it with the 911. Please, someone test the Turbo to unveil Porsche's BS. Unless these measurements start being done by independent comissioners with the same measurement rules, this will keep on happening.
one thing to note is that the GTR also underperformed what it was "supposed to" in several other 3rd party tests.
just take a look at the power-to-weight ratios, explains everything, the GT-R really doesn´t fit and never fitted into the scheme
Haha, Porsche is always the shepherd at the gate when it comes to enforcing rules. Remember the FIA-GT back in 03/04, when they complained that the M3 BMW was running was using a V8 and not based on the production I6?
