High speed ride now getting dangerous

[HSimon]

This problem has probably come as a shock for everyone?.Why does the problem only arise on the road and not on the track?.I thought this car was the be all, and end all of performance and especially,handling.I wonder why all the reviews from all the press, and all the videos have not highlited this problem before?.Nissan will have to sort this problem.I hope they do,regards, SIMON.

Well they can`t sell a car in Germany flying off the road above 180 km/h while it actually can be driven at 290 km/h+.
180 km/h i can go in a 10 year old crap car.
It is just an assumption but 30k EUR difference is not peanuts.

Since no one knows I will just wait and test one when they are available and road legal here.
If it sucks against the Audi S4 i will simply buy that one as it is my other favorite next to the GTR and well suited for German high speed roads

Just my opinion,
I have had a gt3 rs type 997 and when i was on road with irregularity at 200km/h on straightline the rear of the car was bumping right to left and i was in need of compensate each bump to the direction.
The bad things was that if you are not prepared to this then the direct steering on the car was increasing the effects (you bump in your seat moving the steering in the same time) and should finish really bad and more if you release brutaly the throttle at this time.
The tramlinning was also a problem cause of the tire really made for track that redirected every deformation of the road to the steering.
When i was on track this problem was not here and the car was really paste on the line i choose.
I don't know if you understand me (dont know how to explain it in english).

TokyoGTR, First: You guys are barking up the wrong tree. This car needs lower unsprung weight. Get carbon 911 Turbo brakes on it, even if they don't have the stopping power of the Brembos, and get lighter-weight 19" wheels and non-runflat tires with a leeetle bit more sidewall on them. I think the handling will massively improve.



My experience: I still have the limiter, 190kph, and after several 20 minute stints pegged I'd say it was stable and nowhere near dangerous at those speeds. This was on pristine, totally empty highways in Chiba, our tax dollars at work. Higher speeds, I dunno, I can't see it suddenly getting yet more dangerous in a Jekyll-and-Hyde manner.

OTOH if you are talking about the elevated highways S or E of Tokyo which seem alot rougher as well as having lots of expansion joints, then I'd go one step further, even at 50kph the GT-R is really skittish.

At these speeds, the worst highways are like a rocking horse on normal or a hard rocking horse on R, but an actual pogo stick on comfort--the car actually bounces multiple times.

Finally, I think the car's tuning is so biased towards the N-ring, which I understand is fairly rough and has lots of camber/altitude changes in corners, that I would have expected it to hunker down at speed.

Ja sicher, aber an der hinten dem besten GTR wurde "911 Turbo DSG" geschrieben sein...

I do wonder if there is more work to be done here, i agree that V spec version with lower unsprung weight might help. You know its funny, Audi thought they sussed everything with the mark 1 TT, untill their customers started crashing them!

As Coilin Chapman always said, final R+D is done your the 1st customers!

I thought by the all of the Autobahn testings and in-cabin vids of such testing that the R35 is stable up to 180MPH (not km).

So now the tramlining gets worse the faster you go? I thought the opposite.

This is so dissapointing...

They should go "The Legend Is Real" (Disclaimer: Up to 180km/h only)

we should all be writing to our dealers demanding a response to this. We are all taking a leap of faith and its only right that we are handled accordingly

Yea, report that you dont want a car that cant be washed or modified either...if there is a problem, they will fix it, they will have to or the car and their company will cease to exist.

This just seems a bit odd to me. Maybe we in the US are used to rougher roads or something? I thought one of the key features/functions of the body design was to use the aero to apply downward force on the car to keep it planted. At higher speeds this would become more apparent.

This is interesting news for sure. Looking forward to some input from other owners as well.

I say you come drive around Dallas, TX for a week or two and enjoy the uneven concrete roads here. They're good enough to kill all the enjoyment in your daily commutes. Driving my Zed on those roads turned-out to be about 50% enjoyable and 50% aggrevation.

bump bump...........bump bump..............bump BUMP!.............bump bump bump bump..........bump bump...BUMP!......bump.

I am just getting itno this thread a little but what about more agresive front and rear airos to hopefulle reduce some of the bounce and achive that squating feeling that was mentioned above. I might be completly off the wall but what is the thought

[vishnus11]

This sounds like a bunch of BS to me - to put it concisely.

This car isn't your average Malibu. It was engineered by the best to beat the best in EVERY possible environment.

1. Quite a few journalists have taken this car up to 180+ mph. One article clearly stated that they took the GT-R to around 190mph, with a Porsche 911 Turbo following behind, and stated that the car felt rock solid and planted at that speed.

2. Not one single automotive critic has even voiced concern over this so-called phenomenon

3. The car makes 300lbs of downforce on each end at 193mph. NO lift - downforce.

It sounds like the OPs opinion is somewhat valued by some of the board members, but could you honestly for one minute believe that the handling of this car at high speeds is remotely 'dangerous'. What a joke.

Nissan GT R Drivability

"One of the most interesting tests the Nissan GT-R had to pass in the case of high-speed driving was to be able to cruise at 300 km/h (186.4 mph) and allow easy conversation."

feel free to come to japan and drive me if you want.

frank, yes, it does not happen on the straigh tline of the aqualine but on the older roads line chuo and tomei. my mate in his RS4, as i stated before, said the back end of my car was bouncing all over the place. i drove behind him and his car was steady as a rock.

yes, it hunkers down BUT the car is SO high up that this is causing some of the problems. aftermarket suspension lowers the car significantly. now if someone can come up with a lowering kit AND springs without changing the suspension then i'll give it a go.

as for whether my opinion matters or not, it's just me giving you all my unbiased opinion. i'll gladly take the car back out with my mate and have him video what happens at around 200kph on slightly bumpy highway surfaces. btw, yes, it's literally on and off. there's nothing gradual about it at all.

and as franks says, it's bounces around like mad sometimes for no apparant reason.

so, the options are: lower the car somehow and keep stock springs and shocks OR change the entire suspension and have it lowered anyway.

they made the car so high up to clear bumps and ramps in carparks which can be quite sever in japan.

i've done 3000kms on it now, some on fuji speedway, lots of hakone turnpike and loads on chuo, tomei, shuto and aqualine. most of this hard driving was done unlimited, no speed limiter. before the speed limiter was removed i never ever noticed a problem.

mate, i can keep my mouth shut in future and just let you all find out all this stuff for yourself instead.
