Car and Driver scan, performance Options

Oh, thank you Mr. Brain Police. We'll never do it again. You're soooo right. You are important.

Gee,touched by an Angel. I feel better now. Don't You? Sugar Plum Fairies dancing in my head...

I think the biggest thing that bothers me about the changes for the US spec car, other than the softer suspension, is the seats for fat asses. I'm 6'2" 170lbs. I think I might be swimming in these new barco lounges they put in our cars. I may as well order up some Recaro's now. I bet I can find an interested buyer for some R35 GT-R seats.

Drink some milkshakes. Eat a cheesburger.

Hmmm

Seems you did that a tad too much before that silly post.

Feel better now?

[allegretto]

Well, you see...you can control the boost via bluetooth. So, the Nissan guys were linking to cell phones the drivers were carrying and then via bluetooth, they would up the boost during the middle of the tests and then bring it back down to stock when no one knew. Yeah...that's the ticket.

What's the code for that option? Gotta get one!

So if this is Nissan's test mule instead of C&D's, how will Car and Driver do dyno tests and comparison's with it? Did they say they will at the end of the story?
I wonder will Nissan allow them to keep the car that long? Will they be using a different car those tests? Then too how will this validate the tests if they are using different cars for this purpose?
Maybe MoPho can shed some light on that?

550 is correct.

It's probably more like 520 but we won't know until someone pulls the engine actually measures it. Wheel and hub power can be measured but I don't think anyone can know for certain what the drivetrain loss is for a given vehicle.

Thanks for your reasonable post and tone given the circumstances.

Not at all, 550 is correct. Nissan can claim 480 all they want, but I was told well before the car was released that it would have 550 hp. The reason Nissan wouldn't dare say anything about it having 500 or more HP has to do with certain levities against cars in that horsepower level.

Thanks for the scans and MoPho thanks for your info and comments. Either way the fanboys from Porsche / Chevy can really complain much. What makes them think that the 997TT and Z06s that were provided to the magazines weren't ringers themselves? In any case after an exhaust + ECU if the car wasn't making 550 it will be then.

BTW I calculated the GTR's combined fuel economy with the gov's formula I found on wiki. We'll have to pay some gas guzzler tax.

^^^^ I wont even touch that horsepower debate with a long shovel, only to say this: The car has been run on countless dynos and none have come close to 550 hp at the crank(given drivetrain loss). I also got the over 500 hp but I was also told to wait and see what the end result(production cars) will have since different configs were tested.
That's all I will say about that hp debate...

Oh, flattery will get you nowhere.

And you the resident IP attorney?

See how much You mean? Hope I can sleep tonight.

We only had the car for a few hours, any future tests will have to be done with a different car (that will likely be a final US production car)

Then this will be messed up then isnt? If they tested a mule they should test the production car too then. See what I mean? What is the point of releasing this story with a test car, then they will do dyno and comparison with another car?
It does not make sense to me.
As much as I am fan of the GT-R this just dont work for me and I am sure others will agree, to make this 1/4 mile time validate,then the dyno and comparo SHOULD be done with the SAME car.
This simple: when we compare the trap time here (especially), with the time done by R&D, there is a huge disparity!!! I know what the JDM car does already, I am satified with that but the US market is different. Help me understand here, I am a bit slow on the take.

Ummmmm, did any notice the barometric pressure was measured at 25.75 ? Ok, that is lower than any measurement of any hurricane ever...

MoPho - I have heard over the years that Car and Driver & Motor Trend "correct" their times. Is there any truth to this?

First off, the test mule was only a "test mule" in that it was wired up to be able to do all kinds of engineering measurements, for all intensive purposes it was very close to production, if not the final iteration (according to Nissan)
You are also assuming that they won't retest the next car to see if there is any disparity between early production and final production.

Quite often car magazines test preproduction cars in order to get an early story out on the car, and of course this car is the story of the moment.

I can't speak to what MT does, but yes, C/D does correct for weather. They also run the car in two different directions to limit the effects of wind and average out the runs.
The reason for the correction is because cars can't always be tested at the same time or in the same place/conditions, so the correction attempts as best as possible to reduce that variable

It's an older article but this kind of explains it (they use a VBOX on the west coast too now) http://www.caranddriver.com/features/all/2...cars_feature__4

Thanks for the info.

Do you happen to know what the uncorrected times where for the GT-R?

[reillydog]

LMAO

Sorry, I don't, I do believe they were pretty close to what was published
