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 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.

    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.

    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.

    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.

    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.

    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...

    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.

    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 😄 )

    Okay, nice analysis. If I followed, the GPS data and the speedometer data displayed on the laptop (or was the just GPS data on the laptop?) don't agree with video, and the video analysis shows the lower speed. Questions: 1) If the laptop showed the speedometer, why would both the GPS data and speedometer be off by precisely the same amount? That's very odd that two independent speed measurement systems would be incorrect by an identical factor, isn't it? 2) Were the medians noted from the video feed from inside the car or outside? If from outside, then it could still be from the wrong video for the medians vs. the GPS overlay. 3) When's the new speed run scheduled?

In high cross wind conditions on the free way would it be safer to travel at a lower speed 50mph or higher 80mph if the cross winds are gusts of 40mph. I would guess that a higher speed would be safer but I’m not sure. Help

    slow down if there is crosswind because the car gets lift or less downforce. Same when you are exiting from a tunnel because you don´t know if there will be gusts of cross wind outside the tunnel.
