This is the discussion thread for a recent post on GTPlanet:

They are basically pulling out full out race cars to clam the title lol
I believe they've said they made a few changes to the car on Rennlist, but nothing an owner can't do themselves. They spent a week just getting the car setup before the first run and claim its got more in the tank.
It is. By changes, they've been playing with the suspension over and over and over looking for the best setup.Weird. Everything I saw said the car was complete stock, Kumho even gave them a set of OEM tires to use too. If the car was modified it'd make it a little less impressive.
Except unlike Subaru who did use a race car to set a record, the Viper ACR is completely street legal (at least in the US).
I am not sure why but the car looks a little different than stock. Unless the wing comes stock?? Whatever the case that is a beautiful car and it is sad to see it go, however I will never see out the window of those cars since I am a broke ass gamer that only wishes!!

While doing research for this article I think one thing became pretty clear. Do not fit Kumho Ecsta V720 tires to the left front corner of your Viper.
The team hoped it could continue the runs and eventually break into the sub-seven second barrier. However, a series of misfortunes quickly dashed its hopes.
I still have a hard time believing in those lambo lap times at the ring. Lambo's are fast but they've never been known for handling, and they're heavy as hell. Yet they're beating hypercar laptimes. Doesn't seem right.
He was having a little trouble after 2 min. Around 2:48 he misses a shift (he did a few others before that), and check out that steering wheel action from 2:30 to 2:40. The thing is a beast.
I wish they would have put active wings on the car
But is there a shred of evidence it happened?Aside from the fact that Nürb is a pretty high average speed circuit despite all the corners the thing that the Lamborghinis have, the Performante in particular, is aero.
That and as of late they've actually been quite acclaimed for their handling, again the Huracan in particular.
So it was all done discreetly?Yes, there is. Lamborghini brought forth the data from the car to Jalopnik or some other auto reviewer. In addition, a VBOX company went through the onboard video and concluded the time was ideal compared to their Nurburgring data, only adding they wished Lamborghini used their VBOX for even better accuracy as a joke.
TMK, it all started from some YouTube video of a guy comparing the time to the 918's video and how times/speeds didn't match up to certain sections of the track; that Lambo sped their video up. It came off a bit biased and some of his claims didn't match what he was saying, according to those went in-depth. At one point, someone with knowledge of the 918 theorized that the battery pack could've been draining leaving performance lost on the table.So it was all done discreetly?
Afterwards Lamborghini simply posted telemetry?
None of which proves validity of any kind?
By an Italian manufacture with a reputation for hyperbole?
Just want to get the facts straight.
Edit: ok there is a video.
So why are people questioning it's validity?
RaceLogicReal or Fake? There is some controversy brewing over the recent video posted by Lamborghini showing a 2017 Huracan Performante clocking a 6m52s lap of the ring. This piqued our interest, so here is our (somewhat geeky) analysis:
The distance between the gantry and bridge is 1727m which was calculated in Circuit Tools using some customer VBOX data. This was then confirmed using the measuring tool in Google Earth. We then integrated the speed from the on-screen telemetry data on the Lambo every second using the built-in video time-stamps to obtain distance travelled. This data was obtained by stepping through the video in a video editor and entering the displayed speed every second into Excel. When integrated, the telemetry data made it 1728m from gantry to bridge, so the reported speeds and times between these two points on the circuits matched the real world distance precisely. This means that the speeds on the videos seem entirely realistic.
We then analysed the engine sound (using an FFT analysis) from the Huracan at top speed on the same straight, which showed a maximum of just under 7750 rpm on the rev counter. This analysis showed a strong peak at 640Hz which equates to 7680rpm for a V10. Therefore our opinion, based on both pieces of evidence, is that the video has not been speeded up. Next time, it would be a lot easier if they used a VBOX Video

It's certainly not an impossible time, and I love Lambo's, so I am happy to take it as legitimate.TMK, it all started from some YouTube video of a guy comparing the time to the 918's video and how times/speeds didn't match up to certain sections of the track; that Lambo sped their video up. It came off a bit biased and some of his claims didn't match what he was saying, according to those went in-depth. At one point, someone with knowledge of the 918 theorized that the battery pack could've been draining leaving performance lost on the table.
Either way, RaceLogic came to the conclusion the video was not sped up & the info shown matched what they expected to.
Couple their statement with this tidbit not shared. The 918 video used in the comparison used a VBOX from Race Logic as well.
Basically leaving us with a comparison of data pulled from a RaceLogic VBOX against data pulled from Lamborghini's VBOX, thaaaat ended up being supported as authentic by RaceLogic. Marco Mapelli talked in an article about how he achieved the time as well which gave some more insight.
