Porsche Accused Nissan of Falsifying Production GTR 'Ring Times.

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.

Yeah man. That's some fishy shit.

cheater slicks im sure...or they actually used a v-spec/modified GTR on that lap

I saw my first GTR a couple weeks back. Nice looking car. Interesting article though.

welp, nissan made their claim today, swearing up and down it was on the optional dunlop tires...which are basically racing tires for the road, but they arent that much better than the bridgestones on the porsche.


They hinted that it was likely driver error on the porsche side

There has to be a minority somewhere around nurburgring to blame.

Usually the manufacturers only make these claims about rival companies' cars in their promotional videos. There's so much wrong with drawing conclusions from a chassis engineer's lap in cars he knows in and out, followed by a car he's barely driven.
Hopefully this leads to a regulated challenge.

i absolutely blame the blacks

I DIDZ IT!!!!

I shat in the intake manifold WHEEE!!1

I could do that in a Van, 7.29

I cannot believe Porsche actually published this. All they're doing is diminishing themselves.

I expect the GT-R ran it just fine on the optional Dunlops. I also fucking love how Porsche is calling Pilot Sport Cups "regular road tires" - they're R-compound tires with a wear rating of 80! You can buy them pre-shaved because they're so soft that they chunk off if you drive them hard with full tread depth.

There are two possible morals to this story - Porsche is either a sore loser, or (surprise, surprise) their 911 chassis engineer is much better at driving Porsche Turbos than he is Nissans. No shit, eh?

It doesn't matter because the Corvette ZR-1 is still faster and the Viper ACR tore the shit out of all of them.

And the near bog standard V-Spec beat the 620bhp Corvette. Your point?

I think his point is the porsche is now slow

The point is that Porsche is whining about the GT-R beating the lap times of two of their models when in fact there are 6 or 8 other cars including the Carrera GT that have beat the lap times of the Turbo and GT2. Also, the ZR-1 and the ACR beat them as well so why isn't Porsche going after Chevy and Dodge?

And the V-Spec isn't official yet because it isn't a production vehicle and still in testing. The unofficial time is 7:25, which is one second faster than the ZR-1.

i guess they dont respect japmobiles very much

Nissan fires back

Consistent with industry benchmarking practices, we are aware that several auto makers have purchased the GT-R for their own testing and evaluation. Like all GT-R customers, we recommend that any auto maker buying a GT-R should follow the recommended run-in procedures, service schedules and maintenance to ensure the maximum performance from their car....In addition, we offer performance driving courses for prospective and current GT-R owners to help them get the best performance from their car. We would welcome the opportunity to help any auto manufacturer with understanding the full capabilities of the GT-R.

Ouch

cat fight!
