How Fast Is The "331 MPH" SSC Tuatara Really? This video will focus on three questions: 1) What do we know about the SSC Tuatara world record controversy? 2) How fast did the SSC Tuatara actually drive - was the 331 mph GPS speed accurate? 3) How fast can the SSC Tuatara go based on the specifications? We'll do some easy-to-understand calculus to understand how far the Tuatara actually drove based on the video, and use that to determine what the possible explanations are. In preparation for this video, I spoke with Jerod Shelby of SSC, Dewetron (the GPS company), Driven Studios (video production company), Oliver Webb (the driver of the run), and Shmee (the channel that explained the controversy to the masses). Check out the video for all the details!

Engineering Explained
I know us YouTubers say this all too often, but please watch all the way through! This story actually developed amidst my filming of this video, so the video will walk you through everything that happened, and at the end I get some answers to my remaining questions. Thanks for watching!
Petr Svetr
@Hybrid Life I ment he should have said that explicitly in the end instead of trying to be polite (or affraid of lawsuit:-D
Hybrid Life
@Petr Svetr He very clearly showed the answer to be that the run was fast, but not nearly as fast as claimed. Calculus doesn't lie about anything, much less simple things like time and distance.
Renato Maniago
@MrRadicalMoves I use 0.028 for 338 mph.
Jeff0500
@The Ranter That was the point of comparing it to the AGR.
Jey Cee
@Engineering Explained Now do the reverse calculation of crank power in Stradmans video where the Tuatara is on full power @9:40-9:54, sound->rpm->speed, from known transmission and tires, now feed your sheet and you will notice power is well under half of what SSC claim. Now go back and do your homework, for this week: Don't ever trust numbers given to you by someone known for lying! Frontal area is another one easy to debunk, the front view is in the gps overlay, use it to calculate real frontal area instead of the made up numbers SSC feed us.
chris britton
could this all be solved with one man standing at the highest speed point with a radar gun?????
Justin Higgins
Wheel and tire diameter affect the final drive ratio. You can have a 10 to 1 gear ratio with a 30 inch wheel, tire your still high geared.
John Smith
Yeah, just have a tachometer display and a camera showing the wheel rotations.
Lucas A
Still waiting for the re-do...

Math really isn't my strong suit, but you have an excellent manner of presenting data and helping me understand it despite that. Massive props, that isn't an easy thing to do.
Bill Kong
Tesla's gonna have a tough job making the roadster the "fastest car in the world period"
Bill Kong
simplest explanation is the time scaling is off. Everything got played back a little slow so our calculated distance is too long.

This didn't aged well 🤦
Erwin Estrada-jr
soo did they end up witha verified run?? no follow up 3 months later?
neil mchardy
No they didn’t. Bit like the Budweiser rocket which claimed to break the sound barrier but with any accepted scrutiny or timekeeping. All without a sonic boom.
Corazon del Oro
In RE gearing, you need to adjust for tire growth at high speed.
L. Thill
but how fast can it get me to the 7-11 for a slurpee

sooooo in other words SSC could reach a speed of 345 but that isn't too valid because of their credibility so I'd say the Chiron supersport is still the speed champion
Donovan C. Young
Them: We have the data to show this is real.
Us: Can you provide the data so we can verify it?
Them: No.
Us: Thank you for playing, NEXT!
Craig Worland
Too be Fair now they have tried twice and failed twice.

Moral of the story, trust but verify,
David Daimary
It did hit 240 on Stradman's channel in 5th. Two more gears to go so....
mjs28s
Why are we relying on the equpiment in the car for the speed?
Why are there not say ten different speed traps along each stretch of road?
It is pretty simple to time a car across a 66 foot distance, like in drag racing. The car breaks a beam and a timer starts. The car then breaks a second beam and the timer stops. The distance between beams is know, thus you get the car's average speed over a short distance. If they want to be more precise just shorten the length of the speed trap to minimize any additional acceleration in either direction.
All this GPS tracking, car instruments, etc. should only be used as a verification tool and not as the main validation method.
Ayan Dutta
Great video, I have also seen Jesko Absolut's video. While calculating the theoretical top speed of SSC Tuatara the transmission efficiency taken is 0.94 but for Agera RS the efficiency was 0.94*0.93 so taking that 0.93 into account and also 70Kg driver's weight Top speed is coming 337mph and taking the same conditions (Air density, Rolling Resistance, and Trans. efficiency) Jesko is giving 331.25 mph (533kph), though Jesko Absolut has less Cd, downforce, and mass, that 110kW extra power of SSC Tuatara will surpass the Jesko. in the top speed test. If Jesko had this 110kW more power it can achieve a top speed of 346.73 mph. Looking into the theoretical calculation, SSC Tuatara can beat 331mph as well.
Jonathan Schrader
i hope ur math is on point.. I believe the car can and did and will do it again... I believe in u too.. impressive simple math.. u kick ass
TheChzoronzon
I have bad news for you, man: you really can't belive two thing directly in contradiction, at the same time... unless you work forSSC, that's it

So this translated to 251.2mph, before it began to disintegrate lol

The Love Boat, soon will be making another run.
This car, probably not.
Qohen Leth
It's okay to pause for a second or two now and then.
Adrian Untalan
Look at the bright side, you are a lot less likely to get a speeding ticket with the speedometer reading higher than actuality.
Matt M
Bugatti Bolide?
Old men rule racing

But you cannot even guess the theoretical top speed based only on those factors..... I mean you can, if you couch it as totally theoretical, but if you couch it as potential.... which this video seems to do, you are in a world of problems.
Tyres: What are their tolerances.
Temperatures: How are you controlling them.
Pressures: How are they regulated
....f*ck it... this list will be a hundred points long if I list everything.
They already tried and rerun and failed because of elements like this though,.... temperatures I believe.
These guys faked it so badly, and they will need to provide the details regarding the science and engineering behind the individual failure points/elements, of the car, to ever realistically be considered to even have a "Theoretical" top speed of anything close to 350 mph.
b gg
Definitely no election meddling
RagingBlast2Fan
We're not trying to figure out if it was possible for the record to have been broken. The burden is on them to release unedited footage, or have independent observers there to observe the validity of the record. Their run is obviously invalid regardless of the mere possibility that it was broken. I might do whatever I want in my room, but to claim that I broke a record I would need to have and provide proof of it sufficient to satisfy a reasonable person, otherwise we're doing a disservice to not only to the current record holder, but also to anyone who is contending for the title in the future.
Jason
Thusly, according to my calculations... Henceforth, therefore and what have you...
Pete Rivero
Go to the salts flats for records. Simple?
A smart guy Codename47
I think it's 331 kmph, 🤣🤣🤣
robert köhn
They used a finaldrive of 3.454. Compare other videos off ssc like "brutal acceleration" or when stradman joined in the cabine and hitted 242mph. There yoy also see the rev of engine.
Notyo Info
You're freaking amazing dude 😁 thanks and keep it up! I'll be watching for that second run & more videos-:)
Hafizh Gozali
Jason, gonna need that Power Calculation on the New Hennessey Venom F5. just as a good comparison to the Jesko Absolut and SSC "Theoretical" Top Speed
anglin greaves
Maybe the settings got stuck on kmh😂
water1051
Is this a joke? You called Shelby to get it sorted out? The same guy who published the fraudulent results? Either EE has a very dry sense of humor, or I’m missing something.
water1051
How can you possibly say ‘a correction factor of 1.46’ with a straight face?
soccer2864
Guys can figure all this out.. but still don’t know what we said wrong 😂😂😂
Roger Pullin
At a base price of 1.9 million who really cares, sales tax where I live would be greater than $78K, and then another $182.00 a day personal property tax, just to let it sit in my garage, not me, I could not sleep at night.

312 people disliked this because accurate data and math doesn't win races or records lol.
(sarcasm)
BlueRice
its extremely hard to get a car go above 300mph. need massive engine power and aero need to be almost like a butter knife. the hardest part is probably tires. at that speed tires expand and could rupture very easily.
Nico Larsson
I think they took dyno data ... and added it to the video .. No air resistance in the dyno plus that resistance can be adjusted on the wheels. Regards Nico Larsson
Ps
I do not think the speed is from the GPS.
It is the real speed from the speedometer but from a dyno run.
water1051
This is a good theory, but I don’t think they would be able to accurately match the shifting.
dark ages
Tuatara takes close to 10 seconds to accelerate from 250mph to 300mph.
Please calculate the hp (power) necessary to accomplish this.
Utter BS.
dark ages
Tuatara takes close to 10 seconds to accelerate from 250mph to 300mph.
I think that this is utterly impossible for the given specs.
TANVIR AHMED
anyone know when will ssc again perform the top speed run ?
water1051
They have no intention of rerunning the car
merlin 13
Sorry folks but we got caught out with too many questions so we wont release technical data to prove our "facts", thanks for watching anyway.

We also won’t submit the data to Guniess WR

Yuri Kiev
Integration 101, lol.
Jim Ferry
I don't know fast cars, I drive boats and you feel the difference in maximum speed and 2/3 max. I also would never use Dewetron equipment again. You should never be able to dial in a correction factor. Lastly I typically have three GPS' on board not one. there is signal latency between GPS units. Anyway the car looks fast and has the power to put up big numbers.

Hmm sound's like they're hiding something
skruffy79
I think they left in the high DF gearing and then scaled results to the Vmax gearing.....maybe?...
water1051
Maybe, but this doesn’t explain a 20 mph reading from a standstill

Denis Bassom
Hilarious and very informative. This is as bad as all the UK built race engines that shipped to the US, rebadged and then suddenly gain 10% BHP. Still, stunning car whatever the numbers. Can't wait for the follow up.
Captain_Context
When he says "CORRECTION FACTOR" thats actually the cheating factor. The faking factor.
Captain_Context
@TheMattbrownbill Yeah as if Chrysler and GM wasn't doing exactly the same.
TheMattbrownbill
A VAG 'correction factor' 🤔?
Captain_Context
Its funny how they use the Koenigsegg run as base for corrections. Because they know Koenigsegg DIDNT CHEAT.
The Real James Pickering
This world speed record was verified by Donald J Trump.
Bryan Hall
Curious - what is the formula solved for Vmax? I admit I am lost solving for that with V in the equation used twice.
Phil Hawtin
Well done
Hart T
Koenigsegg wannabe
Erik 567
Maybe they need to have a rule that they must go through a designated speed trap for the record. All this extra ways of figuring is crazy and can be wrong.
adb012
Could it be that the video footage is not running at 100% speed? So that 1 second of video is not 1 second in real life?
Samuel Mills
Yayyyyy integrals I love thoseeeee
Cam L
Great video, but you keep using the term “possible” when you really mean “plausible” which makes us purist philosophers go crazy! 😄
Chris Cantrell
Dude I totally feel undereducated after watching your videos

Tony Bjorklund
Data Acquisition devices can have a lot more configuration issues to resolve before gathering good data than one would think. I have used a couple different packages in the past and you need to realize these are tools and you can use them in a variety of ways. Just like a hammer can make a fine adjustment or break a device. It’s all about how it is used.
I think it’s totally possible one of the settings (of which there are many ) could have missed something potentially as simple as elevation or had a mis step on the filtering of the velocity data. No matter what you think, the signals are never 100 percent pure and without noise it’s the natural state of things.
There’s a paradox that happens between filtering out the noise and getting very fast updates you can get one or the other pretty easy but getting both at the same time gets increasingly difficult as the sample rate increases because the events you’re monitoring are happening faster and getting noisier...
j0 m0
Google maps ain't that accurate....
Chirantan S
This guy Schmee is into high end luxury cars and rare cars. So it would not be too far fetched if it turns out that Koeniggsegg paid him to create the confusion!!
water1051
There is no confusion. The record was fraudulent. The only confusion is coming from SSC not publishing the data.
Mike Downs
why didn't anyone assume the correction factor was in the video footage itself. 30 frames per second instead of 24 frames per second.
That would explain the problem I believe.
water1051
Good theory, but it doesn’t explain a 20 mph reading from the GPS when the car is still stopped.
Dave Woff
All that tech and not a laser radar unit in the house?
water1051
No way, that would have showed the true speed of 250-260
David Telllez
SSC has a lot of press right now👏👏
Barry Joslin
“Theoretically it’s possible to scale and filter any input values...”
Maybe this math and “edited input values” explains the Nov presidential election in the US.

Simpler statement: SCC is just a bunch of bologna.
Magnus B
A 22 min video proving that SSC lied, but not actually spelling it out. That's some serious political skills 😁
Brent Bartley
Sounds like SSC brought max downforce package cars for a vmax run, either they screwed up and brought the wrong cars or their vmax gearboxes weren't ready or reliable for a vmax run and then fudged the data because their claimed speeds aren't far off the theoretical top speeds for the specs they claim for the vmax box but the speeds they seemed to have run by video analysis are close to the max downforce car's theoretical top speed.

Weird... the video I just watched proved they didn’t lie. 🤔

Roland Jacobsson
Just a guess, perhaps someone wanted to apply some low pass filtering like:
Vnew = a*Vprev + (1-a)*Vcurrent
But accidentally missed the ”1-” part :)
alex vagny
I don´t want to enter in the loop of comments questioning if one can trust on the organizations that certify world speed records.
Something interesting that I noticed here, is that the Cx has been declared as Cx=0.279 and then SSC has provided to this youtuber with Cx= 0.314 @ 500km/h with a set up to get just the necessary downforce for power transfer and no turn maneuvers (I assume due to compressibility effects). I know that SSC has measured the previous vehicle model (Ultimate Aero) at the NASA Langley Wind Tunnel and that nowadays nobody tests a ground vehicle in wind tunnels at more than (about) 230 km/h. I would appreciate if someone here has run CFD on different sports cars at very high speeds and calculated all the aero-coefficients (benchmarking 😄 )
russell hays
great video as usual... you do a great job explaining the math behind what you do.
daniel strayer
Was the camera frame speed verified?
