GTR Nismo Nordschleife time (im)possible in AC?

I just took 458, MP4-12C and GTR for a quick spin on the 'Ring before heading to bed and I did 7:31/32 in all three of them with 95% grip and default setups. If you take a look at their real life lap times it would mean I'm right at it with the Ferrari and McLaren or 2-3s off (couple lap times posted). Especially that manufacturers "cheat" a little by not counting that short straight between the finish/start line.
Now as can be seen on the video below the GTR is 20s faster than the best lap times of the other two. 20s!

So is it something wrong with AC's version of the GTR? Or maybe Nissan did some "tricks" in order to achieve that time (like Honda for example)?
Of course driver is driving like crazy and I'm not trying to take away anything from him. Lol, just look at the video, huge respect to him. But amateurs don't drive factory "record" lap times either, so as I imagine the other two cars have their proper lap times set.

I know I'm not as fast as some of you guys, but figured that if I'm hitting pretty much the same times with the 458 & MP4, I should be close(-ish) to the GTR time too.

So maybe a little challenge for aliens?
Or someone knows what's the "story" behind that incredible lap time?

 

This was discussed a lot back when the car first came out. The lap Nissan did was with a car that had upgrades that they said would be available to customers. These upgrades never actually became available. I believe they also did some tuning specially for the car on the Nordschleife and who knows what tires they used. If I remember correctly William Levesque managed something around a 7:15 back then. My opinion then was that the car was still a bit too slow despite all of this, but the time Nissan did is not a great representation of what the real car can do.

It should be in this thread.

 

Yeah, did 7:15 back then, but then you also need to take off around 5 seconds. They don't do the small pit straight. Not sure how fast the car is now.

The 458 and 12C times weren't "flyers" IIRC. Not sure how seriously they should be taken.

 

Ah I see. Thanks guys.

 

I think the Nissan is a bit quicker then it was, not sure whats possible on optimum settings but may give it a run later. I did try in the earlier build and going side by side against the real car it wasnt even close conpared to the real car the . My RSR time was 7:20 I see but think I went a few seconds quicker around 7:17 then with it nit running which is about 7:11 minus the pit straight.

There is also now a nismo attack model available which you can buy and supposedly the same as the car that set the "official" lap.

Sorry for OT, but is that a reference to Honda Civic Type R's "fastest FWD road car" record? What's the story behind that record, what's the "trick"? I'm just curious.

 

Indeed. Just from the top of my head, roll cage, no AC. There was a thread about that record here.
Also on another forum some people were suggesting that it drives significantly faster on the straights, which would mean it had more hp than the stock one.

 

There some info about the N Attack package here that brings the upgrades to the real car. In conclusion, yes, the GT-R in AC isn't equal to the car (not just in model year) that achieved the lap time.

Well then I call Nissan's time BS.

 

Well yeah, it's disappointing. It created the impression that the exact car sold, or with upgrades sold by Nissan (which it didn't at the time) could run that time. On the other hand it's still amazing that the car is so capable with a few upgrades that make it still clock in under the competition in terms of price.

Either way, that's why you can't quite compare the times between Nissan and AC.

 

I really wouldn't use optimal grip for setting record and comparing them to real ring laps. I doubt ring is ever in perfect condition. I heard it's slippery even with clear weather and warm temps. That said, it's pretty high up.

 

"I just took 458, MP4-12C and GTR for a quick spin on the 'Ring before heading to bed and I did 7:31/32 in all three of them with 95% grip and default setups"

 

I generally run all tracks with green track conditions, 20-26° ambient (except for tracks I know are in very warm climate), some morning/afternoon time (affecting temperatures), often full or near to full tank.

 

@sarabwt: They're somewhat equal, I get similar times, with the MP4-12C being the fastest, GT-R Nismo and then 458, but it's a 4 second difference at most from slowest to fastest.Honestly, I think Nordschleife times are too much of a taboo subject and a somewhat weird proving ground in real life, you see all kind of advertised times, with different chassis setups, tyres, drivers, conditions, there are so many variables, if you'd try to come to a meaningfull comparison I think your brain would explode .
Recent hot hatch times, Corvettes, the GT-R's and even though I'm a bit of a Porsche fanboy, even their lap times are a bit...un-detailed.

 

I really didn't.
And won't.

I always use 95%, 96% or sometimes 97% grip when doing a "proper" lap on the 'Ring. If it's full layout then I'm also always using default setups with 60l of fuel (not in all cars as some has 40l etc.). On BTG I usually mess up with setup.
I don't really use 100% at all and not only on Nordschleife.

Fully agree with you. I treat it purely as an entertaining value. And as I already said the other time, if two cars are very close to each other on this track it doesn't really tell us which one is definitely faster. Since there are too many variables.
It's still cool to do some comparisons between AC and RL though.

 

I wasn't really aimed at you, just in general.

 

I was quoting the OP ;D

 

100% surface grip will be whatever the main road of the track uses in the data folder-surfaces.ini. So several tracks have 0.98 friction, including Nordschleife.

 

@V8_KB: I'm actually lapping all the street cars in AC on the Nordschleife in the same conditions so I can make a baseline for myself when racing, but it isn't incredibly conclusive, there's still a margin of error (driving skills), and so I tried to do them with the minimal amount of practice on each try (max 2-3 laps).I might upload them to YouTube at some point.
@saranwt: My bad, heh, I'm a bit tired.
By the way, talking about the Nismo GT-R's time, since we have the normal Stingray, do you think the Z06 would be able to get in the 7:20's? The chassis on the Z51 Stingray is very nice, some aero and more power+tyre grip would prove really nice on the Nordschleife, there's still something left to squeeze out of that chassis for sure.

 

I know that, but I doubt nords is grippy.
