SSC Tuatara Top Speed run apparently faked?

[Hazmat1]

Detailed examination...

How do you do that without the one piece of definitive evidence? The GPS trace

[anonymous-user]

The GPS trace they recorded is what’s shown on the screen in the videos. Therefore the analysis we have seen already includes the GPS trace.

Edit: And if you had access to that trace you would not be any the wiser. It is the discrepancy between the trace and footage which is being called into question. A GPS trace can be falsified, which is why records are normally verified by Guinness, FIA etc.

Look there's a fundamental problem in that we know the rpm, gear ratios, final drive and what gear the car was in. Its a PHYSICAL IMPOSSIBILITY that the car can do over 293mph in 6th gear as it was throughout all the runs.

Also, no direct quotes from Dewetron. Please watch the Misha Charoudin vid with Robert Mitchell to understand this properly.

Is it possible to swap out the ratios in a CIMA transaxle box?

Their website is as clear as mud https://www.cimaingranaggi.it/en/solutions/product...

I did. And the Shmee video. They both say the same.

It's a great story. Will make a good Netflix series!!

I really don’t see the need for personal attacks?
The F1 thing was anecdotal, failure to understand that is on you.

From previous posts it does indeed look like hard GPS data is now being looked at, hopefully that will settle it without the needless a d unpleasant name calling

Would love to move some cacti and a couple of roads signs, film a speed run in a Sandero and watch the commentary community froth themselves.

One thing I don't get is the tyre factor.

I posted this on Shmees YT analysis.

" Can't argue with any of that. Another point though and please correct me but, when Koenigsegg did their run... Michelin were present. They came in support and to also gather data on their tyre.
Did they not temper going any faster (300 +) as they were just not sure if the tyre could take it? Granted this was a few years ago but still...
Then these guys rock up with no apparent support from Michelin, use the same tyre and 'claim' to fire off this speed record?
I'd love to know Michelins thoughts on this alleged record"

As said, the Koenigsegg run was a few years ago now and perhaps Michelin have improved the Cup 2 and /or taken that the tyre can reliably run at much higher speeds for a relatively short period of time in the tyres life?

Comments/thoughts on this from PH?

I did wonder this, more so from Oli Webb's perspective than anything else. Surely he would have wanted a few reassurances before attempting something that could easily kill him instantly? As well as safety of the road itself tyres would have been top of the list of things to have wanted to know the limits of.

Is it plausible that the car did do 331mph, but was so unstable at that speed, that they overlaid the gps data from that run over the video of the 280mph run for marketing reasons? The first thing I noticed when watching the Top Gear video the first time was how little the steering wheel moved, I was impressed at how incredibly stable it was at speed. Maybe at 331mph it was super squirrely, and would have spooked potential customers. Either way they need to explain themselves, and publish the full gps data set.

Even if they did it, the test driver was so scared he wouldn't do it again, It really shouldn't be about the record. I never heard anyone say that about Bugatti, but there budget was billions, not a few million.

In a twist to this, my friend who had recently returned from North Korea where he’s been used for fitting out old UK train stock for Kim was contracted to some work on the SSC.

He’s told me that the SSC engine was swapped out with a chipped intercity 125 diesel for the runs to be verified for the record. Meaning that the run will get the record for fastest car and train at the same time. Apparently Kim is pushing for diesel to be faster than maglev in 2021.

Make Diesel Great Again - MDGA is his slogan, again I don’t want to push conspiracies but I think this was taken from an American website when Kim was snooping around for plans on how to make the worlds fastest food blender.

Surprised nobody’s linked to this vid

In the run at 9:53 they are reaching 240mph at 7krpm in 5th and they reference mph.

I haven’t looked at theoretical max speed in 5th but the crux of one of the arguments was the theoretical max in 6th was 296. Not a massive stretch to say it would be in the realms of that based on the speed in 5th in this video.

Considering stradman veryron is relatively early - (254 mph) was a bit surprised the tuatara didn’t destroy it, if it supposedly has 330mph potential.

And you thought Shmee was annoying, this guy is on another level. Interesting none the less

Copy and pasting what I wrote on the other thread about why the GPS overlaid on a different run theory doesn't work :

That's debunked as in this VR video look down and to the right with your phone, you can see the GPS laptop giving the telemetry readout live, the gains in speed exactly match the gearshifts at the start for example. My theory is that the telemetry is being spoofed 'live' if that makes sense. Could be as simple as the laptop being configured to show a percentage over the Ecu/true GPS speed readout. This is given further credence as this time the speedo in front of the driver is totally non existant, it's been erased!

Wouldn't the simple solution be to do the run again? Its a production car so it should be able to do it more than once.

That's probably the one thing I would understand if this is a legit run. Whilst most of PH would understand that a speedo would understate the speed, many people would probably question why it's showing what would probably 20-30mph less than the GPS speed.

Speedos overstate though

Sorry that's what I meant, the sentiment is the same though: confusion.
