Is it? Back when I watched it, I learned a lot, looking in deep to the aerodynamics every week, technical information about development current and future.
TLDR: they probably used a smooth ground belt for more consistent and less wear-dependent simulation data because of their limited number of tests but underestimated the ground boundary layer and its effect on the ground effect cars caused by a rougher, more realistic road surface.
Thank you. Honestly the video didnt need to be that long. Felt some of them was just utter BS to extend the video for content. Seriously though.. how does explaining how a wind tunnel push and split air has to do with anything? Dude.. get to the point. Sooo painful to watch

Not very glamorous but I used to clean the carpets now and again at the Red Bull wind tunnel site. The scale F1 cars were amazing, even under the bodywork everything was duplicated for working out cooling and fit under load.
I want to thank Willem for turning up and explaining this stuff to us. For years I used to read magazines like Autosport and wonder about how teams either moved forwards or back in performance, and study the differences between aero on the photos of races. It always fascinated me, but of course I was basically just trying to guess. So I greatly appreciate this level of explanation. It truly puzzled me how Mercedes not just dropped the ball in their design but took so long to fix it. This explains an awful lot.
Would rather have the entire interview than your commentary. Not that the commentary is bad. But because such interviews are so rare. Can you upload the entire William Toet interview?
So Ground Effect era significantly altered how critical the surface texture of the track is to performance. Restricted wind tunnel tests for Mercedes combined with a test “road” surface that was too smooth meant their testing failed to demonstrate real world performance. Consequently, Mercedes spent a long time in the dark as to why their cars were performing so badly compared to their own expectations.

Great information, visuals, explained in a way that doesn't require expertise. Fantastic channel, I appreciate all your efforts, this is better than most stuff on TV, much less YT.

That was the best video about F1 aero I’ve ever seen. I’m so sick of being shown details of floor skirts and wings etc to try and get excited about each teams’ updates but this was informative.
Aerodynamics is a huge and very interesting subject. A close friend of mine develops small scale radio controlled speed run cars. Building and racing 1/12, 1/10 and 1/8 scale vehicles at over 100MPH is not as easy as some may think. One current project even uses active giro assisted steering, electronically adjustable spoiler and rear wing providing live micro fine control of aerodynamics and downforce. When You are changing the surface roughness of the paint on specific sections of a body shell to gain an extra one or two MPH You know it's going to be a fun week. Often wished we had a wind tunnel to test the RC cars in as doing all testing and development outdoors, effectively on track R&D, makes it so much harder to get consistent data but after seeing some of the complexity of wind tunnel calibration issues maybe we are better off with live outdoor testing. Always very interesting to hear from professionals who live and breath aerodynamics. Thank You for these excellent videos Sir. Keep up the good work.
Super detailed piece Scott. The information gained from U're vids comes in F1 increments. Little more here, a little more there. There's always something new to add to the picture. Many thanx & as always, best regards 👍👍
Thanks Scott, another belter, no pun intended. Makes a mockery of "Adrian can see air flow" and helps us recognise the complexity of aero. I don't particularly think Mercedes dropped the ball but rather were a part of the FIA's desire to level the playing field for the time limiting reasons you discussed. Almost feels a shame to be heading to a new rule set when the field is finding a balance but what a great season we are having.
Wow I actually did a project on the Prandtl Boundary Layer for a fluid mechanics module at university around 5 years. Haven’t heard it mentioned since then until now.
"Deliciuously Complicated" reflects EXACTLY the challenges of full scale correlation aerodynamics. Kudos on your excellent video and to Wilhelm for his super insightful comments.
Wow, what a great video. The explanations of how a wind tunnel works and all the factors that need to be taken into account for accurate data really helped me to understand the aero of these new (2021 and beyond) F1 car designs. Thanks!

It's a lack of institutional knowledge. The industry figured this out in the 80s, but by the 2020s, all those people likely retired. Few people were around to remember why they wanted the rough belt. And if they did remember, they might have thought they could try and run calculations to fix it.
@@lazydictionary Eh, I think it is probably the latter. I highly doubt top tier engineers working for F1 teams don't understand or know about these concepts. They probably just thought they knew better and could account for the variables in their calculations. They possibly had pressure put on them by Mercedes to keep costs and complexity down as well. Who knows though.
Thanks for the explanation! Brought me back to the old days when I took two fluids courses in my undergrad. It sure explains also why the ground-effect F1 cars are just so sensitive, especially to floor damage.
Turbulence per se is not a bad thing. In fact, turbulent boundary layers are prefered in areas where strong adverse pressure gradients exist to help avoid separation. You confuse turbulence and separation.
1977: Lotus founder Colin Chapman realized - thanks to a mistake in the manufacture of the side pods of the JPS78 Formula 1 car - that by putting a flexible slat on the bottom outside edge of the side pods, the car cornered significantly faster than without them - as standard F1 cars of the day only had wings for aerodynamic aids at both ends back then. It ultimately led to the JPS79 that gave both Mario Andretti and the late Ronnie Petersen the fastest (if not the most reliable) car in F1 leading to Andretti winning the driver's championship, Petersen (who had passed away from injuries sustained in the Italian GP) posthumously securing second place, and Team Lotus securing the 1978 Constructer's championship.
This should have been titled as a generalised wind tunnel & aerodynamics education piece, the Mercedes angle was just wedged into the last 2 minutes to give the video a clickable title
youtubers need to please the algorithm to get their videos shown, blame youtube. i would absolutely complain about a youtuber being clickbaity were it entirely unnecessary, but the algorithm gods must be worshipped if youtubers dont want their channels to just stop getting promoted
Could you maybe interview willem on how their workflow is, like which programs they use and how (like its said mercedes is using star ccm+, redbul is using ansys and williams openfoam etc) but how do they test and compare stuff to their windtunnel runs, how do they improve, how fine is their mesh (the "accuracy" how their model before doing cfd tests), do they use math or some sort of trial and error shapes if testing new parts for certain areas of the car etc. This is nerdy but super interesting!
Worked briefly at Mercedes F1 (Old Honda) in Brackley for the 2012 car. Amazing facility, Brawn would walk around the office and it was the days when Schumacher was still racing. Good times
More than 16 minutes into a 19 minute video, you finally describe the problem from the video title. You make very useful content but the title is misleading clickbait.
I was frustrated by this too. And the answer only took a couple minutes to explain. Plus there were two host read advertisements and three RUclips advertisements during the video. Way too many.
I think you misunderstand the whole video. Fluid dynamics is a very complicated topic and you cannot condense it into 3 minute video. The context that Scott provides is actually very important to the conclusion.
It's like when Uni students are complaining that they have to take "bullshit" courses like math and physics in the first few semesters. It's needed to understand the ones that they really want to study. The first 16 minutes (expect the ads) are needed to fully understand the last 3 minutes
Great content for a technically minded fan. Loved hearing about some of the more detailed aspects of running a wind tunnel, and linking that to Merc's performance issues. A nice alternative to hearing Toto or Lewis giving their view of things, that is obviously from a substantially different perspective.
Sounds good. A lot of talk about the rolling road and boundary layer air. But, the facts are that a 60% model in a wind-tunnel with air moving ONLY at 120 MPH will just give you data related to the full size vehicle traveling at 72 actual MPH! Mercedes created a great "lifting-body" design for their 2022 entry into F1.
I mean you could always pay for YT Premium I suppose if ad free is really your thing and it’s a deal breaker watching otherwise free content with a smattering of ads? Free choice is yours.
If only something like fluidjobs existed 5yrs ago when I graduated, I would maybe be somewhere completely different than I am now... But where I'm moving, there is sadly very few to none motorsport entities, and remote jobs are not quite numerous in the industry. Thanks to all the team for the video!
I find it really interesting that redbull went with the zero pod concept this year (Albeit less extreme) and it also ended their dominance. (Also less extreme) I wonder what was so appealing about the concept that even after Merc failed they decided to pursue it
@@lolomgwtfbbqqqq they did a wrong upgrade in Barcelona 2023 apparently, when they had the least time and even less with the penalty, so yes it affected them as well
@@lolomgwtfbbqqqq bro go read some articles, im not just talking shit, what did you think? and if that doesnt convince you, just look only one year later for the obvious effect
There are limits on Computational Fluid Dynamics (CFD) generally cadence fidelity. 25 Tflops I think depending on the last season manufacturer position.
What does this teach us: A good driver (like Lewis) only becomes champion if he is backed by the best engineers. If the engineers make a mistake, no matter "how great" that driver is, he cannot push that car to do miracles and win championships. In other words, Lewis was lucky to drive a Mercedes and not a Haas in the years when he won.
This is not news though. The competition for the drivers is not fair and never was. That's the result of the technical arms race we all love and enjoy seeing.
A brilliant video explaining some complex stuff so that even I think I understand. I now understand what a lamena flow wing is and some of the stuff my flying instructor tried to teach me about drag. Thank you
Gemini summarized this: Mercedes' wind tunnel testing issues that caused their F1 dominance to end in 2022 were due to the following reasons: Rolling Road Surface Roughness: The team used a smoother Rolling Road surface than the actual track, which led to inaccurate data on how the car's aerodynamics would behave in real-world conditions. Limited Testing Time: Mercedes was restricted to 36 wind tunnel runs per week in 2021 due to the aerodynamic testing regulations, which made it difficult to conduct enough reference runs to calibrate their data." Focus on Performance over Calibration: In order to maximize their limited testing time, Mercedes prioritized performance testing over calibration runs, which led to further inaccuracies in their data. These issues combined to give Mercedes a false sense of confidence in their car's performance, which led to them making poor design choices that ultimately ended their dominance.
Rigorous and detailed engineering/physics dialog. Good on you! Could you add a piece about the actual changes to the sidepods, T-tray, and bottom plate throughout their engineering recovery from porposing. Go Hamiton!
I‘m sure you know all the basics of aerodynamics to understand the conclusion. For all orhers it is important to understand WHY the road surface has this influence
WHAT A TOPIC!!!! F1 AERODYNAMICS!!!! YESSS!!! Actually, I was talking with one of my peers engineers of my work about the MB F1 that is the Power Unit Supplier for McLaren and Williams F1 and I was saying what Aerodynamics was so important in F1 and I used the comparison between McLaren and MB F1 cars… Using the same Power Unit and look what McLaren was capable to do with the Aerodynamics upgrades….

I came to write a similar comment. You could hear the passion in his voice as he was saying it. Good stuff
loved this video! very interesting how seemingly small things can make such a big difference!
You have too many ads.
Best explanation on this topic by far!
1977: Lotus founder Colin Chapman realized - thanks to a mistake in the manufacture of the side pods of the JPS78 Formula 1 car - that by putting a flexible slat on the bottom outside edge of the side pods, the car cornered significantly faster than without them - as standard F1 cars of the day only had wings for aerodynamic aids at both ends back then. It ultimately led to the JPS79 that gave both Mario Andretti and the late Ronnie Petersen the fastest (if not the most reliable) car in F1 leading to Andretti winning the driver's championship, Petersen (who had passed away from injuries sustained in the Italian GP) posthumously securing second place, and Team Lotus securing the 1978 Constructer's championship.
Excellent visual explanation of the differences between laminar and turbulent fluid flow.
This should have been titled as a generalised wind tunnel & aerodynamics education piece, the Mercedes angle was just wedged into the last 2 minutes to give the video a clickable title
Sad...
The life of a youtuber
And they are basing their facts on the opinion of a guy who wasn’t even there.
Amazing complaints 🙄
youtubers need to please the algorithm to get their videos shown, blame youtube. i would absolutely complain about a youtuber being clickbaity were it entirely unnecessary, but the algorithm gods must be worshipped if youtubers dont want their channels to just stop getting promoted
Truly Great “Stuff”!!!
Your presentation is invaluable.
Thank you 🏎️🏁
Your fluid mechanics lecture was more than all the classes I've attended in my college
0:12 they weren’t allowed to spend $400 million + on there car …
they was before covid
On catering? Like red bull
Their*
And they're not allowed to do 1000 km of secret tyre tests and get away with it anymore, the FIA has found new toys to play with 😂
love the fluid dynamics dive. A series going in-depth on the aerodynamics as well as testing and development of f1 cars would be amazing.
Could you maybe interview willem on how their workflow is, like which programs they use and how (like its said mercedes is using star ccm+, redbul is using ansys and williams openfoam etc) but how do they test and compare stuff to their windtunnel runs, how do they improve, how fine is their mesh (the "accuracy" how their model before doing cfd tests), do they use math or some sort of trial and error shapes if testing new parts for certain areas of the car etc. This is nerdy but super interesting!
Wonderful video! 👏👏
amazing that this channel has 1.27m subscribers but the contents are mostly just touching the surface of basic engineering and technologies.
Worked briefly at Mercedes F1 (Old Honda) in Brackley for the 2012 car. Amazing facility, Brawn would walk around the office and it was the days when Schumacher was still racing. Good times
More than 16 minutes into a 19 minute video, you finally describe the problem from the video title. You make very useful content but the title is misleading clickbait.
Welcome to RUclips where clickbait is the new normal
I was frustrated by this too. And the answer only took a couple minutes to explain.
Plus there were two host read advertisements and three RUclips advertisements during the video. Way too many.
I think you misunderstand the whole video. Fluid dynamics is a very complicated topic and you cannot condense it into 3 minute video. The context that Scott provides is actually very important to the conclusion.
Fast forward to where you want then. I enjoyed the context. So for me, GFC, and theres a reason hes got a channel and you don't. ESAD
It's like when Uni students are complaining that they have to take "bullshit" courses like math and physics in the first few semesters. It's needed to understand the ones that they really want to study. The first 16 minutes (expect the ads) are needed to fully understand the last 3 minutes
Fantastic video! Keep them coming!
Great content for a technically minded fan. Loved hearing about some of the more detailed aspects of running a wind tunnel, and linking that to Merc's performance issues. A nice alternative to hearing Toto or Lewis giving their view of things, that is obviously from a substantially different perspective.
Just on a completely different note, my boi Red Bull still rocking a World War wind tunnel
More of a Cold war era wind tunnel, that has since had 2 major component upgrades too
@@into_the_void It still nearly falls apart, google mk7 redbull windtunnel, ofcourse they use modern equip, but only modern equip that fits
It was used to design the RAF's Tornado fighter plane
@@quadrantalerror1121
Not the Spitfire?? 🙂
Sounds good. A lot of talk about the rolling road and boundary layer air.
But, the facts are that a 60% model in a wind-tunnel with air moving ONLY at 120 MPH will just give you data related to the full size vehicle traveling at 72 actual MPH!
Mercedes created a great "lifting-body" design for their 2022 entry into F1.
Two in vid ads and two RUclips ads and I gave up at 11min
Think it’s bad now? Look into RUclips about to roll out ads on paused videos, as well as targeting ad blockers
I mean you could always pay for YT Premium I suppose if ad free is really your thing and it’s a deal breaker watching otherwise free content with a smattering of ads? Free choice is yours.
Premium absolutely worth the cost ….equivalent to a coffee or two per week…so far.
Get premium, support your creators directly
brave browser or ublock origin, will never see a youtube ad again
If only something like fluidjobs existed 5yrs ago when I graduated, I would maybe be somewhere completely different than I am now... But where I'm moving, there is sadly very few to none motorsport entities, and remote jobs are not quite numerous in the industry.
Thanks to all the team for the video!
love all the weird bot comments
They never disssapoint
It was a great video with great insides!
haha they come into an f1 video like "WOAH MY BOYFRIEND WANTS TO BLOG LIKE THIS, GREAT CONTENT GUYS"
Just what a bot would say
So many ads
I find it really interesting that redbull went with the zero pod concept this year (Albeit less extreme) and it also ended their dominance. (Also less extreme) I wonder what was so appealing about the concept that even after Merc failed they decided to pursue it
So the ATR allocation did its job perfectly
Doesn’t explain why red bull did well
@@lolomgwtfbbqqqq Adrian Newey doesn't need a wind tunnel. He draws on his drafting table and his mind simulates the airflow.
@@lolomgwtfbbqqqq they did a wrong upgrade in Barcelona 2023 apparently, when they had the least time and even less with the penalty, so yes it affected them as well
@@NeumannKlaus you're seriously going to reference 2023? The year when redbull won every single race except 1?
@@lolomgwtfbbqqqq bro go read some articles, im not just talking shit, what did you think? and if that doesnt convince you, just look only one year later for the obvious effect
That Conveyor-Belt moving @180 is *nuts* Pretty cool you can also Steer too
WHAT, they limit the times they can do research???????!!!!!!! Thats nuts
Paraphrasing, yes, they limit (very expensive) wind tunnel time and thus money. Same money = more equal chances more level playing field.
There are limits on Computational Fluid Dynamics (CFD) generally cadence fidelity. 25 Tflops I think depending on the last season manufacturer position.
@@l.d.t.6327who cares how level the playing field is though??
@@disgruntledwookie369 “who cares” -> not me.
Interesting, so they're trying to limit throw money at the problem until there is no problem. Thats awesome.
Fantastic video! It makes me more excited about this sport!
What does this teach us: A good driver (like Lewis) only becomes champion if he is backed by the best engineers. If the engineers make a mistake, no matter "how great" that driver is, he cannot push that car to do miracles and win championships. In other words, Lewis was lucky to drive a Mercedes and not a Haas in the years when he won.
Very true. But don’t forget the checo-Redbull side of the same coin! Just because you have a quality car doesn’t mean you’re guaranteed success
And Max was lucky because only Redbull nailed ground effect cars and no one was able to catch until now which is Losing every race .
At the end of the day, to win a championship, you need the best driver in the best car. One doesn’t work without the other.
@@sadushukle2141 That's pretty self evident for any example for that matter, irrespective of it being Lewis-Mercedes or Verstappen-Red Bull.
This is not news though. The competition for the drivers is not fair and never was. That's the result of the technical arms race we all love and enjoy seeing.
A brilliant video explaining some complex stuff so that even I think I understand. I now understand what a lamena flow wing is and some of the stuff my flying instructor tried to teach me about drag. Thank you
Skip to 16:00 to hear about merc.
"Deliciously complicated" 😂
Thanks. I was only wondering the other day if wind tunnels have evolved to allow for pitch & yaw etc. the other week!
Gemini summarized this:
Mercedes' wind tunnel testing issues that caused their F1 dominance to end in 2022 were due to the following reasons:
Rolling Road Surface Roughness: The team used a smoother Rolling Road surface than the actual track, which led to inaccurate data on how the car's aerodynamics would behave in real-world conditions.
Limited Testing Time: Mercedes was restricted to 36 wind tunnel runs per week in 2021 due to the aerodynamic testing regulations, which made it difficult to conduct enough reference runs to calibrate their data."
Focus on Performance over Calibration: In order to maximize their limited testing time, Mercedes prioritized performance testing over calibration runs, which led to further inaccuracies in their data.
These issues combined to give Mercedes a false sense of confidence in their car's performance, which led to them making poor design choices that ultimately ended their dominance.
Awesome video!! I greatly appreciate the depth of the subject matter! Very well explained and written!
It would be great to see this kind of wind tunnel testing done on the Rally 1 WRC cars to understand their sideways grip and also how they jump.
Very good video. Complex topic and I still understand it (or at least I think I do). Thank you.
This video is amazing! Thanks for sharing so great insights!
4:45 just glazes over the fact the FAA regulates air speed...indoors...on the ground.
Indeed.
FIA, it’s the governing body for Formula 1.
Fantastic video, the best on aerodynamics easy to understand that I’ve seen. Subscribed.
Rigorous and detailed engineering/physics dialog. Good on you! Could you add a piece about the actual changes to the sidepods, T-tray, and bottom plate throughout their engineering recovery from porposing. Go Hamiton!
Willem is my favorite guest of yours, Scott!
I love these videos, I am learning so much so thank you for that, and keep it up!
RIP ChainBear
What happened
What!?
WTF?
Maybe the best technical F1 video I've seen.
10:30 siren
19 minutes long for a point that can be conveyed in 1 minute.
"How Wind Tunnels Are Used by F1 Teams" would be a more fitting title
I‘m sure you know all the basics of aerodynamics to understand the conclusion. For all orhers it is important to understand WHY the road surface has this influence
WHAT A TOPIC!!!! F1 AERODYNAMICS!!!! YESSS!!! Actually, I was talking with one of my peers engineers of my work about the MB F1 that is the Power Unit Supplier for McLaren and Williams F1 and I was saying what Aerodynamics was so important in F1 and I used the comparison between McLaren and MB F1 cars… Using the same Power Unit and look what McLaren was capable to do with the Aerodynamics upgrades….
That’s what I love F1 but specially, AERODYNAMICS!!! And @Driver61 and Scott Mansell bring to us!!!
So, BIG CONGRATULATIONS TO YOU SIR SCOTT MANSELL Sir Williem Toet! Big Fan of Mr. Williem Toet!!! I have been following him since late 80’s….
I have a masters in aero and all these principles are pretty basic and we learn them in year 1-2 of school. This won’t be where Mercedes messed up, it will be far more complex.
Excellent as always. I love these interviews like Jayemm with Steve Nichols
you did two midroll ads before 7 minutes? Bro, I gotta leave. I'm not hear for more commercials than a f1 production.
Just skip forward with the tap of a finger it’s not hard
Fast forward. How’s he supposed to earn a living doing this for free on RUclips???
