A heads up here that the JKF Race Car Aero Course will be going on 30% off sale for the first two weeks of July, get in while it lasts! Hope everyone enjoys the video!

Exactly the kind of video I need at 5:00 AM.

To me the Red Bull floor looks so much more advanced than the others we have seen. They are doing so many unique things. All the other teams under floors that have been seen so far look almost generic but Red Bull have some great sculpting. You can really see how the outer two barge board strakes work in this picture. And in the rear how they are minimizing porposing.

AMR engineers: "Write this down! Write this down!"

Kyle you’re amazing. These breakdowns make me appreciate F1 so much more. I’m sure other teams are benefiting greatly from seeing these photos and studying them just like you. However you verbalize it for us. Thank you

Fascinating, I need to watch it a few more times for understanding. I made underbody molds and attached vortex generators for Nissan GTP and Toyota (AAR) Champ Cars in the 90s. I only had limited knowledge then, but it was always interesting.

Could you do a 101-style video on vorticity? I get lift, drag, pressure, separation etc from my undergrad days, but vortices and what they're used for I've never quite wrapped my head around.

Enjoyed that. It's about creating and managing vortices. And Newey

Awesome video. This is exactly the reason I'm a fan of F1. The cutting edge engineering is fascinating. Thank you for all your superb aerodynamic analysis videos. They really help me think through what's happening with the airflow. Great job!

Since you worked for mercedes from 2018 to 2020 I went back to mercedes amg video for celebrating their 2019 WCC and when celebrating outside the brackley factory, I saw you behind Bottas, so cool

This is fascinating. Appreciate the technical analysis!

Your expertise is amazing. I really appreciate you providing access to your knowledge for free.

Thank you. I appreciate that you don't pretend to be absolutely certain about what's going on with these cars since you don't have the team's data. People who believe their educated guesses to essentially be facts are not good educators but you are..

Exellent work Kyle, I love your videos mate. The aero is maybe my favourite aspect of F1, so your videos are incredible

Thanks for another great analysis, Kyle!

It's crazy how even how this isn't a educational course type of channel how much this dude has helped me better understand things in some of my engineering classes intuitively

Fascinating. Kyle you're amazing. A very exciting video. I had to watch it a few times to understand it better. But very exciting. Hope we can still look under the underbody of the other cars. There are nice pictures of the Ferrari underbody.

It's very interesting to get explanation for the floor, thanks! You pretty often see the floor of the cars when they are removed from the track and it's very easy to spot the huge difference compared to previous regulations. But exactly what and how the differences are and the purpose of the shape of the floor is impossible for just a fan. So to get this in-depth breakdown is awesome and also give a hint of how complicated the floor is. Especially with all the creating of vortex and how important they are. Also I thought the fins in the front of the floor was there to direct the air under the floor but the outer two directed the air outwards which was interesting since I thought they really wanted as much air as possible under floor to create downforce.

I love how organic the design looks. Its interesting to have seen this evolution in aerodynamics design that started with inspiration from nature and were now able to mimic and exceed the beauty nature provides

And here we are a year later, RB underbody exposed again. Waiting for an update to this. :D

Was really hoping you would do this video. Many thanks!

Thanks for the in depth analysis.

Amazing video Kyle, really intriguing to know the technical side of F1. Thanks for the video.

I find this stuff fascinating. So glad I found this channel. Keep up the great work!

I have next to no idea what you're talking about, but I appreciate the effort you put to this. Well done.

Love your stuff, looks like you beat the official F1 contributors to explaining the RB floor. Great work!

Finally...the only review ive been waiting for 😊

no way i have been taking so much information that has helped create one of the most successful race cars of all time

Another great vid there! Would enjoy some DTM car analysis, also some very interesting aero vehicles in the Eruopean Hill climb championships. likewise the annual Pikes peak in the US, always an aero delight

You REALLY know your stuff. Well Done.

Excellent professional analysis - all the vorticity reminds me of how the dragonfly's angular wing is actually more effective because of the vorticity it generates, which is counter-intuitive to traditional models of smooth surface lift.

I was hoping you were going to do this analysis, thanks mate

It’s funny. On the F1 podcast earlier this season, Pat Fry was talking about the 22 Rules and said some something to the extent of “the rules are written on a way that allows a wing under the floor. Why you’d want that, who knows?” Well…

subbed! impressive stuff to learn from

great job as always thanks alot

Amazing video

What a great video. Be cool to see a comparison of all the floors for which there are photos. Not sure if all the cars from last year exposed their floors, but any comparison would be sweet.

This is so fantastic because it lets you appreciate the level of detail that goes into these aerodynamics without any actual engineering. Like if a rival team were to decide they liked this they would have to come up with an actual geometry and run analysis to see the numbers it generates and then incorporate that into a full model to see how it impacts the whole system.

Aston Martin furiously taking notes

Just goes to show the insider knowledge Newey retained from the previous ground effect era and what incredible detail they've put into action. Almost like a bird from underneath with it's wings being the modelling for venturi tunnels as that's what gives them the best aero gliding skills.

The picture shown at 18:00 shows a very interesting angle on the floor edge wing “skate” too and how red bull have designed it to interact with the folds and cutouts

Now if only we could get a good high res of the Merc floor, love your break downs on the aero and legality.

Great vid 👍👍👍

Great vid

Time for an update after Monaco 2023

18:40 - it's vertices again too - in a straight line

Kyle, very interesting as always. Perhaps I have missed it, but it would be interesting to understand the upkicks on the front suspension that seem to lead into the double bargeboard. And how does the double bargeboard work ? Does it load up the sides of the car at speed to help achieve variable sealing (ie reverse effect of the M-B stays as the rules do not rule out body work movement, just wing movement?).

thank you for the video mate. just a heads up on 2nd part of porpoising video, i'm egarly waiting for it. don't want to sound ungrateful, i really like this video alot.

Because Adrian Newey, that's why. GOAT aero master!!

Do you remember the days that RB had the engine exhaust flow directed at their diffusor? The front strafes appear to be serving a similar function of creating a vortex of outflowing air to the sides that create more "isolation" of underbody air.

Very interesting video! Thank you. By the way,I also heard that the Ice skate device can work as physical limit to porpoising as when it touches the ground the car can't go further down, do you think those devices can be resistant enough ?

any chance you can do a technical breakdown of the hoonipigasus? I'd love to see the differences they used for pikes peak vs f1

Love how “organic” the floor looks

Another great vid … thanks If I could make one observation… it’s difficult to see what you’re talking about with the legality boxes when you move the mouse around and change the focus of what’s being pointed to so rapidly

I was watching a video recently about an rc scale model of a top fuel dragster and it went into the aero or more correctly the downforce generation in them. The rear wing is obviously the most notable aero feature on them and that together with the front wing and it's massive lever effect means there is tonnes of downforce when they get some speed happening. I'd actually love to see a bit of an analysis of the aero forces on a typical dragster. The speeds are ginormous but I doubt there's any other vehicle with such a huge amount of downforce and such an apparent disregard for any reduction in aero drag.

Is there any chance you can do a video on the difference in effectiveness of duckbill wings vs GT style wings and when you would use each of them?

Horner will be spitting! Would be good to get a side by side comparison, see how advanced this is over the competition.

Please please please make a video on the new aprilia RSGP fairings. It's something that i always imagined could be possible but never thought would be applicable. I suspect they are trying to make downforce with ground effect since their new fairing is so close to the asphalt at max lean, but i don't have the experience to be sure and also a bike is a very different platform from a car.

Mercedes needs you back asap

And we got Ferrari, Merc and Red Bull floors this year too. Waiting for an analysis and comparison !!!

The RB underfloor looks alien almost. Fascinating

Outstanding Kyle. Thanku

Is there a possibility to get the CAD model of 2022 those reference volumes?

This is a bit off topic but can you make a video about the aero of Mercedes-AMG One?

Wondering if they have any party tricks involving those metal plates near the plank.

When another video Said that ground effect in f1 was like upside down aircraft wing, this isn't what I imagine

Interesting, according to the legality volume you can stick a keel separating the left and right side of the diffuser.

Do this kinda video with every "leaked" floor pic, plz

So much detail. I wonder how many teams would use these videos in a briefing for their aero departments.

Best waking up

Awesome tech video. I believe I know the answer but did this video potentially show Mercedes engineers anything they didn't know about the RB floor? Also seems to me once the they see these photos it should be much easier to simply copy? Or is this testimony to having to match the aero of the rest of the car?

my geek brother, thanks!

is it possible to download the legality box CAD model? Or can we find somewhere it?

It feels like I am watching something illegal... And I shouldn't be watching this, and you shouldn't be making this. But OMG I am loving it!

Thank tou

Finally I get a full picture of these Cars. A Model in my head I can work with. Interesting to see Red Bull having so many flow energising parts on their flor but still are the quickest on the Straights. I bet Aston Martin made big eyes when seeing these pictures. Though I have to say, seeing such sofistication so early kinda concerns me with future improvability of the Design, seen as they aren't near dominance like Mercedes was. It gives me hope for Ferrari.

What do you think about the porposing and how redbull is dealing with it better?

Kyle, absolutely brilliant video, as always. Thank you. A question; couldn't the 'ice skates' be serving the purpose of walling off some ait through its vorticity? You mentioned something similar, and I might be misreading the angles, but to me it looks like it could actually block some of the messy air from the floor cut outs, pushing it to the wheel, while allowing lower frequency smoother vortices to keep on towards the rear of the underfloor. And just to point, I know your target demographic is not the general public, but tbh even I at some points in this one lost a bit of my sense of direction while you rotated and moved your models around - when we are agents of the movement it is always smooth and easy to follow, but if other person is rotating the model, the lack of reference can be disorienting. I have no idea how to make it more accessible, but maybe you could investigate it?

What software do you use for CFD?

hi newer cars have wider tyres, and sporty cars have wheels (tyres) that require wider fenders and the wheels themselves stick out more to match the width of the fenders (vs cheap cars the wheels are tucked in). how do these 3 factors affect aero? - wide tyres, tyres narrower than rim, wide fenders, tyres tucked inside vs pushed out wide (not wider than fender). thanks (assuming no aero to deflect all air away, ie the underbody and side air is strong ...)

Pls show these in CFD or ANSYS or COMSOL so that the we can see the air flow cleraly and better understand of that floor

Do you have your own shop? im Located in Australia QLD, and looking for custom work for a time attack car.

Curious if you have any good reading material advice on tunnels vs. pure flat bottom or just tunnel development in general on a 100% track car. Redoing almost all the aero on my car and playing with the idea of developing a tunnel to improve ground effect and downforce over the flatbottom I am currently running.

Assuming every shape in this incredibly complex floor has a purpose, I’m blown away at what they managed to develop with limited tunnel time. Watching the Red Bulls on track, it’s obvious they nailed more than even the giant Mercedes in floor development. Speaking of limits, what is the tunnel time limit all teams are subjected to for new car development?

They have to create two channels the upper channel has to have a faster flow with a venturi at the beginning of the channel to pickup the flow from the lower channel.

Wow 11 points ago this had happened I didn't even remember this

Can you do Mercedes floor review as well ?

I wonder if anyone got photos of Russell's rolled car recently?

in principle this could be measured in a wind tunnel, right? however the design of it... hell hard, there are so many parameters/things to model... how about the drag?

Kyle you're doing AMR a favor. They got the topside and now the underside. Lol jk.

You definitely “geek out” on all those winglets and other devices. What I noticed and was looking at was the “plank” and how it was fastened and how the fasteners actually made the plank no longer perfectly flat as the fasteners were tightened they caused dimples in that plank. So that begs the question, as a aerodynamicist have you ever thought of theses types of issues, after all some mechanics are gorillas and others have a deft touch with there wrench’s. This can in one degree or another affect how all of the panels and surfaces interact with one another. Would you agree or disagree? If the teams go through all the trouble to tape up all the seems of all the panels each time they go out so it’s as smooth as possible, if you get a person that is screwing panels in so tight that they change the shape of the panels then what’s the use of all that fine tuning and testing?

One thing I can´t get my head around is the fact that, at least it looks like, only air passing through between the inner strakes is fed to the middle of the floor and to the diffuser, whereas the rest of the air is being outwashed to the side of the car to help seal the floor. That being said, it seems that the intake area of the air that is fed to the floor is actually smaller than the middle section of the floor, how does the air gain velocity then?

Anyone know how to model a f1 2022 floor in CAD?

Merc and Ferrari engineers obviously appreciating this…

Please RB19 too after Monaco now :)

Great video as always. Could anyone go into detail as to why having this vorticity through the under-tray and diffuser is beneficial?

What I'm seeing is that the floor is asymmetrical, quite remarkable! Thus, its probably circuit dependant, thus, circuit changing!! Newey = genius!! Dan fallows will probably be the first to properly adapt am's floor to the rb's.

Sometimes it is difficult to determine which way is which (front or back) when seeing the pictures or even the drawings. So please try to help us out here :-) Otherwise: Very interesting!

Perez gave us another more detailed look this year, too! lmao

I would have loved to have seen Horner's face when that floor was exposed to the worlds TV cameras 😂😂
