7:38

Scans should arrive shortly.

In summary:

16 Seconds faster than the Turbo
11 Seconds faster than the Z06.
2 Seconds faster than the GT3
5 Seconds slower than the GT2
On par with the GT-R (although a second faster at Hockenheim)

 

Sounds like he needs more seat time.

 

Sounds like a ZR1 is about as fast as the GTR around the ring. I mean it would only be fair to let HVS have more seat time in the ZR1 seeing as how the desired results have not been achieved through this test.

so apart from so called street legal race exotics like the Gumpert, the ACR etc. Porsche is still Ring King, or not?

 

The ZR1 completely stock has lapped the 'Ring in 7:26.4 with GM egineer, Jim Mero driving, the GTR with R-compound tires and T. Suzuki driving went a 7:26.7 and the fastest Porsche CGTonly went 7:28.7 with Walter Rohl at the wheel. Its easier to drive the automatic GTR then having to actually have the talent to be able to drive the manually shifted 6 speed of the ZR1.

Let's break this down again:
ZR1: 7:26.4 completely stock
GTR: 7:26.7 R-compound tires
CGT: 7:28.7 completely stock

 

amen.

 

Shhhhh don't tell the GTR drivers that a 605 lb ft RWD manual transmission car is harder to drive than a paddle shifted AWD 435 lb ft car!

 

Having owned vehicles with different engine/drivetrain layouts all I can say is that a R/R engine car like a GT2/GT3, a F/R car like the ZR1 or a M/R car like the CGT or a F/AWD car like the GTR each one of them will have a different inherent handling nuances, so the way that you drive them is probably going to vary from car to car, so I would not really qualifiy that as having more or less talent. With the exception of rally car drivers and drivers that race on ice, those guys are nuts

BTW: IIRC the GTR was running the OEM Dunlop's so probably not R-compounds, not sure about the boost though, easy to tweak things around on FI cars, who knows given how ECU's are tuned to adapt these days maybe even running higher octane fuel can increase the HP as well.

What is considered stock varies from vehicle to vehicle, the 997GT2 and 997GT3 both came from the factory with R-compound tires, IIRC the Ferrari F430 Scuderia also came with R-compound tires from the factory as well. (other vehicles like the Exige, Elise, M3CSL, etc, etc come to mind as well)

At the end of the day laptimes at the ring gives you an idea of the potential performance of a particular vehicle.

That being said because of the many different variables involved, even such simple things like alignment specs, tire pressures, new tires vs old tires vs mid-life tires, green engine vs broken-in engine, type of gasoline used, etc can affect the handling/performance of a vehicle (thus laptimes), take a Viper ACR, or a Porsche GT2 or a GT3 with their adjustable suspension at what point is a vehicle considered stock vs non-stock?

Overall it is nice to know that manufacturers are pushing the performance/handling envelope of their vehicles.

Cars like the CTS-V that are civil and yet can do a sub 8-minute laptime at the ring are a good sign for auto enthusiasts (regardless of brand or marque affiliation)

At the end of the day if you have the car-nut gene in your DNA be happy with what you enjoy driving or are planning to drive in the future

Just my 2 cents.

 

The GT-R lapped the 'ring in 7:26.7 on the stock Dunlop SP Sport 600 DSST runflats that are fitted to the base model GT-R. This was verified by Porsche and Car Magazine UK. In fact the only only reason Porsche had representatives there was to inspect the damned tires. The only non-stock component used was the Nismo wheels.

Dunlop has not and will not develop an R-Compound run flat tire. There is simply no need for a run-flat race compound tire. The two requirements are at opposite ends of the spectrum.

 

You cannot inspect a tire by looking at it so how then did Porsche verify the tires? Please show us where they did so and stop add-libing your own drivel.

 

very well put. too many arguments going on about one car being better than another.

 

Great post as well, I prefer to vote for my sports car of my choice with my wallet. Instead of putting on a cheerleading skirt for a car I don't even own so I can insult people over te internet!

 

i assume they read the label on the side wall.............................................. .................................................. .................................................. .................................................. .................................................. .................................................. .................................................. .........lol jk but seriously porsche was present for the runs they made in April, as was general media coverage.

as far as inspecting the tires, i dont recall any specifics on what they exactly looked at. however im sure they took the liberty of fully inspecting the car. again not 100% sure... just sayin.

 

and there you have it folks

 

From what I've read, Nissan stated that particuar run was performed with R compound tires, but who knows the source was the Nissan Press room according to Wikipedia.
