Hey guys, hope you enjoy the video! A side note that my aero course is currently on sale for Black Friday if you want to get in on that action: courses.jkfaero.com/courses/race-car-aerodynamics-the-definitive-course Worth noting too that that inboard bulge on the diffuser top surface on the 3D model is larger than I would've expected just to cover a gutter - perhaps they were running a stay or a pressure tap here too?

"Or you have a little bit of a mishap like Williams did and accidentaly release the 3D geometry of your car online"

Your mustache surprised me more than the reveal of the diffuser secret.

Do a breakdown of the stache

Loved this video! I love small quirky rule interpretations like these. Could you make a video about the 2026 aero regs? they might not be enough info about the actual design of the cars but the inwashing winglets and concept seems interesting, kinda goes against what you want and it does make me question what teams will do if they inwash the front tire wake, id love to hear your thoughts about it!

I'm a layman, but have followed F1 since the mid 90's. You're showing me stuff I'm deeply interested in, but in a way that I can easily understand, at least conceptually. I really, really appreciate that. Fantastic video.

i can't wait for the 24 cars i hope you make videos about them love your insight on them.

Actually this idea was first used by Rory Byrne on the Ferrari F2002, where he did put a step in the transition between the diffuser and the flat floor. Another of Rory Byrnes many ideas and concepts copied by others untill today, just applied best to that set of regulations. But the idea of pushing that even further was very clever!

next video Aerodynamics of an epic mustache!

I love this type of video. Thanks for taking the time to make these!

Thank you! You have a way of explaining what is effectively high tier motorsports aerodynamics in a way in which anyone who is even just slightly interested in aero can clearly understand and visualize. Thanks for keeping the channel going strong all these years.

Very nice graphics. Well done. Makes this complex topic easy to understand.

Very interesting! It's always nice to have a video from you..

best tech channel when it comes to f1 aero thanks mate you are a blessing

wow how did i miss this one!! so many questions from the past, now answered

This is such an awesome video. Really dig learning why some of the cool little tweaks teams ran existed.

Great video! You explained everything very well

I’m surprised that a coordinate system of of water lines, butt lines, and stations, referenced from a datum, similar to employed in aircraft design, isn’t utilized, to define the dimensions of the aero systems, in a standardized manner. Very enlightening presentation. Thanks for sharing.

Thanks for the video! It has been a long time. I already can’t wait for launch season 2024 and your analyses

I would love to see a video on your idea of an ideal formula car. Keep the same wheelbase or thereabouts, but have aero freedom. Would it be a more simple shape like the 1980s, or would it have the various flips and flops and flizzles. If it wasn’t for the limitations, would they have a much smoother shape?

Saw you in a WTAC video working on Feras' car. Was pretty cool.

Finally! Been waiting for a new video

I have a theory on McLaren, I think they pulled a bit of a Tracing Point; I postulate they copied RB’s floor from last season and are just now learning how it works. I know it’s not really relevant to the video but watching this video, it crossed my mind.

Your videos are a rare gem!

Really hope you are doing rewies on the new cars as always! :)

The gutter on the Ferrari example appears to be vented out to the sides somehow. I wonder if that yields a secondary benefit of allowing the boundary layer to reform at the edge of the gutter that helps tolerate a steeper gradient for the diffuser.

Excellent video, this reminds me that you were contemplating doing a video about the Fan of the Gordon Murray T.50. Seems to tie in with this video a little bit. Are you still planning to do this?

I’ve seen top fuel drag cars use that gutter aerodynamic factor in inlet ports. They could make running streams, run down the port and over the ports valve seat and into the combustion chamber.

Love the mustache. I've been trying to get mine that good looking

Hey Kyle, can you make a video where you explain how you design Wings, winglets and the transitions surrounding them? Also an other question: Why do you use the splines with pullingdirection points and not the ones, where the spline runs through your point?

Is it the new lighting that made Kyle looking much paler than before? Hope everything’s fine n take care mate

There’s no way there aren’t way more ‘worst kept aero secrets’ in 2022-23 F1 cars right? Would love to see more videos about overlooked features & details

hello, I really enjoy your videos, I am curious if the CFD runs are set up with "rotating" tires ? thanks !

Suggestions/request for a future video: Why don't the current F1 cars appear to lose any performance when they lose their front wind endplates?

Interesting video, thanks for sharing. Can you share insights as to why Mercedes seem to have struggled so much these past two sessions. The no-pod experiment caused so much porpoising and seem to have much higher drag than their primary competition.

I would like a video on the little wing Aston put under the rear jack point

Do you think you could have a place where people could ask questions about the aero stuff you do? because I have so many questions and I would love some answers!

Love the stache.

A great example of the old adage that there’s nothing new in F1. Williams (and no doubt others) had a similar feature in the early 2000’s as a work around for a very similar rule.

WAIT YOUR BACK !? YEAH

Is there anything in the rules that say you can’t have multiple radii in the “floor edge” box? So you could turn the floor up and the turn it back towards horizontal to make a long, shallow diffuser prior to the “diffuser” box.

I'd love a video about the wec cars

Will there be new f1 cars aero videos this year?🤞

It would be great to hear why all the teams changed the upper section of the tail end of the 2023 cars all started having a very narrow tail resulting in the very straight line heading to the rear wing versus 2022 where they sculpted a smooth transition. I havent seen any explanation for this change and all teams seemed to have made the similar change.

Could you please do an analysis of mythbusters golf dimples car?

Can you do a after season analysis based on the floors photos that goes public?

I would speculate that this is, perhaps, one of the cases where CAD rises above traditional methods of design (pencils and drawing boards). At least, from your great demonstration, it's easy to see that, just by playing with a single variable (in this case the max radius) one could arrive at a geometry like the "gutter". I am no saying that traditional design methods do not allow for such realizations, but it appears to me, at least, that drawing something in CAD does allow for a better visualization of the limitations imposed by the regulations, especially in regards to highly complex areas where multiple reg articles coincide.

I appreciate the explanation here but while this interesting subject in a very nuanced way I can’t help but think this is ultimately a bad look for the sport if the performance differentiators between the guys at the top and bottom are things like a 10mm step in the floor. I really wish the future regulations would allow more technical freedom since we now have cost cap controls and basically what will amount to a spec engine format in 2026. It seems like the tighter and tighter they write the rules the more you need a phd in aerodynamics to understand why the Redbull is winning every race.

Can you please analyse the 2024 formula 1 cars, I really enjoyed the videos of the 2023 cars analyse

I think it would have been good if you explained it a little more in the beginning. I wasn't sure if this was a feature on pre 2022 cars or post 2022 cars. Seems like it's used on both pre and post, but just saying when it was introduced roughly and that it's still in use etc would have helped me out a little. There was a bit of the assumption the audience is as familiar with it as you are.

I've wondered this for years now. Is attempting to use a forward kick line and some F1 specific rules the reason F1 will usually use a forward expansion diffuser? Or are there other benefits beyond just moving the kick line forwards? Ones you can actually speak of, of course. Would it translate to other non-F1 aero packages well?

What program is this?

Didn’t know the front wing is behind the front wheels nowadays 😂 oh midjourney

Williams releasing their designs online were hoping people copy them, so that they'd get confused and slow down, allowing Williams to close the gap =)

So pretty much right after you left merc they started making some wack aero lol. Maybe you were the secret

Teams: "We misinterpreted the rrrules"

Mr Movember, love it

Another GREAT detailed explanation of the theory of fluid mechanic/dynamics applied to the real world scenario of a Modern F1 car. But as a mechanical engineer, I do have one question that has been plaguing me the entire season. And I am asking you because you have actually worked for a modern F1 team in that department. With the underfloor shots of the Red Bull on full display for the past two years (courtesy of Checo) coupled with the wide open ended shots of its suspension layout, why is is so difficult for teams to copy and paste and even improve upon their concept of using the kinematics of a suspension for capturing and managing airflow underneath the car? Especially when you have to consider the VAST amount of brain power and computational power they have at their disposal. Once you did your floor analysis to show show Red Bull's approach for generating downforce was more exponential with a curved roof as opposed to everyone going for a linear maximum downforce model I just knew all the teams would realize that's the only way to really manage it with the limitations of the new suspension regulations. I am curious as to your thoughts about why my favorite team, your former employer 😊can't get it together, at leas conceptually?

Thanks.

The best teams ending 2023 es season were using front push-rod and rear pull-rod (McLaren and RedBull). Is this the way to go?

Patiently waiting for the 2024 breakdowns like 😇

RB is supposed to be scrapping RB19 and going a whole new direction next year. Most of the teams think they are playing catch-up with RB. But if RB is moving the goal posts then how could anyone really stand a chance, obviously RB discovered something, if you remember Christian Horners comments after the RB19’s floor was seen, he said something along the lines of “by the time they figure out what we’re doing we’ll be into something else”, that’s not a direct quote. Two questions for you..Why wouldn’t they try to improve on what they are doing to save costs? Second, what is really going to change, it almost has to be a side pod change doesn’t it?

Ridiculous. I love it

Imagine being in a motor sport so restrictive thst any liop hole, even if it isn't proven to help anything, is a good loophole.

Kyle, please use transparent colors! Sometimes your drawings make it hard to see what it's behind them :(

These are the reasons why i love F1. The engineers still find these little quirks with such tight regulations.

The moustache gives us truth.

kyle kyle kyle kyle kyle kyle kyle kyle kyle kyle please do more video please pllease

Shame on you, UKposts algorithm! Why did you hide this channel from me for all this time?!

I want to break freeeee

Please apply for a job as lead aerodynamic engineer at Haas, and help them improve 🙂

Was there a NDA preventing this video prior the end of season?

i think about you when you don’t post 😢

Kyle leaves Mercedes...... Mercedes become slower afterwards.....Hamilton Leaves . Kyle is the first domino.

Please return to Mercedes Kyle, they need you!

Bro are your eyes okay?

Could you have saved them from ZERO POD? :)

Hold up….Williams did what now?

Nigel Mansell has lost some weight

So you’re the reason the w13 & 14 have trash aero, they need you buddy

Could you open your eyes, please?

Dude how much is your baby crying?!? Man needs a sleep! 😂

Will ya repeat that mercedes intership before every single video?

ai thumbnail 💀

Cut the stash man

Also what is with all these 20 something dudes rocking mustaches again? Not saying kyle is one but ive notice A LOT of ppl doing this lately

Your mouth has an eyebrow

Love your videos, but PLEASE stop constantly moving your mouse around. It makes it impossible to keep attention on the part of the drawing your are referring to.

Sorry to say, but with your mouse bouncing around so much, it is impossible to follow which area you are pointing to. So I gave up.

your panning and zooming is too frantic. do better
