A quick reminder that my Aerodynamics course has now launched over at courses.jkfaero.com/ ! The number of people signing up so far has been amazing, exceeding my expectations! I hope everyone is enjoying it and learning lots! p.s. I'm working currently to bring PayPal as an alternative payment solution, looks like it should be available early next week.

kyle struggling to make a car inefficient enough to meet reg is gold

Amazing analysis and case study!! Peugeot designers would be fighting to have you on their aero team; they'd have a lot more artistic freedom hahaha

Love it, great analysis that quiets the critics. Love the rules of the LMH and the freedom it gives manufacturers.

Really great video. I now understand the motivation behind this category. Guess we could see a lot of manufacturer interest over the next few years.

Now THIS is what I like! Thank you! Great content! I haven't been paying too much attention to the regulations but seems a great way to get some OEM features on the cars. Much needed on WEC for my liking!

Who the hell unliked this video haha, I really like how you’re building these demonstrators in CFD!

I know you traditionally do racing performance related aerodynamics analysis but would you consider doing a video or two on fuel efficiency aerodynamics as in Aptera trike, Arcimoto trike, or even semi truck? It would help diversify reach in audience and potential students.

Nice one Kyle, that's one of your best yet. Keep up the good work.

Just love your videos. Not my area of expertise but been learning a lot from you. Thanks you for sharing

Fantastic video Kyle as usual, really enjoyed this one

Seeing you CAD up a car yourself like this was really instructive. I'd love to see you do something like that again in the future!

Theory of mine: The little parts in the front intake are there in fact to make the aero/drag worse to not overshoot the targets... also the cutoffs at the rear diffusor! With that little overbody aero i'd guess this thing is slipping through air like a hot knife through butter. Maybe they need some parts that create more drag?! Btw... this car just looks insanely good. Maybe best looking car ever... to me at least.

Great video, really nice of someone of your abilities to explain all the details 👍

I've just discovered this channel and I found a large variety of really interesting topics covered for a mechanical engineering student and formula SAE team member like myself.

I’ve been waiting for this.

Great work buddy. Your effort is impressive.

This is AMAZING! So interesting and informative. You earned a subscriber for sure this is such a well made video and well explained! Thank you

Awesome video, thanks for uploading this

Thank you very much. I learned a lot in a short time, my kind of teacher!

The car looks amazing. I am supporting Peugeot this year

This is my kind of video, just nerds out on how something works, you got a new sub ⬆️

Super interesting, one question I have is, given the single adjustable element constraint, would the central low-pressure of the floor allow for it to be treated as a fulcrum such that simple balance of the system can be achieved by just the front element? For example could a change on the front effectively stall the floor at the same rate or is the floor fixed in it's effectiveness?

Elite content. More of this, please

I just found this channel and I love it

Learning a lot! Thank you so much !!!

Amazing analysis of the car, Kyle. Lets see how the car does in testing.

Love the video. It would be awesome if you could make one specifically on the aerodynamical advantage of a footplate at the front wing of an F1 car.

Great video!

Awesome video! I would love to see you talk about Fusion 360 and/or your modeling process!

thoroughly entertaining and informative video!! Super awesome to gain an understating of how the Peugeot will work on a track!!! could you analyse the other current hyper car spec cars (the Glickenhaus and Toyota) for comparison???

Aero lessons for dummies - well I understood it! Brilliant vid

Awesome, awesome video.

Wow, amazing. I would love to see analysis like this of Red Bull X2010 :-)

Great to see the CFD analysis. Although the modeling makes it clear Kyle is an engineer and not a designer ;)

Great video! 👍🏾👍🏾

Fantastic video! Interesting that the regulations are set up to (sort of) encourage styling for aesthetic purposes.

It's right there in front of us! Kudos to the design team! They are taking the forward air Resistance and killing the rear Drag coefficients! This is a air conversion system.

First, Kyle your videos are incredible. I have been a ME for 5 years now, and wasn't sure what discipline I wanted to end up in. With other influences including your channel I have fully decided where I want my career to end up. I am finding all of the aero, suspension, and power train elements of all of LMP2, GTE AM, F1, Indy, and other racing divisions so intriguing that I am determined to seat myself in a development position in motorsport. I hope to be as successful as you, but as you have shown, it is obtainable which has opened my eyes SO MUCH. Thank you. As for adding PayPal for the course, will there be a fee associated? I'd much prefer a PayPal purchase if possible :)

I bet Jim Hall loves this!!! 😊

There is hope that the prototypes might recapture the beauty of earlier eras. I may again become a fan this upcoming season.

Holy crap I'm super impressed by that model you can just throw out like it's nothing hahah. Specifically if it's meant to run analysis on. Because I have made several CFD runs for my college team of Aero Design (RC aircraft) and I struggle massively when my geometry isn't super clean. As a struggling student and admirer of your work I would love to see that CAD video, I hope it's already out there

A review of the Vision 1789 aerodynamics would be a great watch. Also, maybe you could do a series reviewing the aero of the more extreme Vision Gran Turismo cars like the Mclaren Ultimate Vision Gran Turismo.

These lmh cars look beautiful. I'm excited to see what volkswagen's cars will look like.

i would love to see an aero analysis of the 2022 F1car. its probably the most overengineered aero concept ever. i think whats interesting is how they get maximum downforce with creating minimum vorticies to reduce dirty air. so i am very curious about the details of the floor, how they seal it etc

The Design is certainly something different, exciting imho and it aligns itself perfectly with the current road car design philosophy especially with the upright lights, as to the winglessness, which at least shows a different way of going about stuff instead of keeping with old formulas, Königsegg also removed the wing for the highspeed model adding two straight lines for side stability and probably quite a few more will follow with the design direction

Definitely rooting for Peugeot in 2023, for the sole reason their car just looks so freaking cool. Crazy how in a field with factory Porsches and Ferraris the Peugeot is the best looking.

Would definitely like to see you analyze some group c / imsa GTP cars. They had some huge downforce claims.

That Kicker as you call it on the back is actually a Kamm Tail wing … so no rear wing is just a generous interpretation of the design. It’s well done I admit and no doubt effective …

something I'd like to hear more about is the difference in downside and drag for prototype/ sportscars having a splitter Vs a front wing. Seems designers in the past have gone one way or another but I'd love to know the science behind those decisions!

These videos are always so interesting! I think I'd be fun to see an analysis on some old cars, like the crazy Pike's Peak Quattro S1

That video was awesome! How about handling? Would it be more on a knife edge or less? Thanks again for the off the charts -I wish I was more qualified to understand better- content.

As a video idea, because I am very interested in this: Could you do something like this (design a own car or aerodynamics) but with a front mounted engine, for example the Panoz gt1 or lmp1 car but as a modern interpretation. because I think it would be interesting to see if you can do a ground effect car but with a front engine. (just a front engine, so still a rear wheel drive car, not like the Nissan lmp1 car....)

I would love to see an aerodynamic comparison between an open wheel car with a halo, an open wheel car with a full aeroscreen, and an open wheel car with neither. I also would like to see some other miscellaneous aerodynamic experiments... like covering a car in fur, or using forward-swept wings, or some other crazy stuff like that.

The channels in the central front fairing is to direct the air to cool the engine, some to the air filter, and to provide some downforce, directing it to the back wings, across the wheels to the rear winglets, it's nothing to do with style, although you might think that because of the way that they look, similar to the lights. The side scoops are just to cool the brakes, no style thing going on either, it's simply to provide air and cooling to the brakes. The scoop in the centre of the car, across the roof through to the rear type of spoiler, is to push down the spoiler with a trumpet like outlet to increase the air out like a silencer on an exhaust, to provide downforce, clever

Great Vid. We've known for decades that cars with ground effects don't need wings. F1 in the ground effects era had cars that would in some races use a front wing and some races not. When the car had a front wing quite often it was there to balance the car front to back. when the front wing was missing it was the rear wing that was used to trim the car out. My bigest question about the 9x8 is how they balance the car out in changing condisions. We all know how rain effects what a car needs but a race track is a living breathing entity. Its total grip level can change especially in a 24 hour race. The tires can even react differntly from 1 race to the next or even 1 practice session to the next , so how do they deal with it. and what do they do if the main floor gets danaged slightly. the other cars can adress these problems by adjusting the wing

Kyle you should do an update video for this car now that the final version has been released!

Great vid, nice analysis Please what application was that ?

Would love to see your opinions on the next gen nascar.

Can you do an updated video of the 9X8? They showed off the actual race car in May I believe.

Please do more LMH and F1 aero videos.

I think the new rules will make for different looking cars with similar aero, and with power limitations we can have different designs but cars that are reasonably similar on performance. Here's to looking at more interesting designs.

I know maybe its hard. but this things is buzzing my ear What if you do some interview with Frank Stephenson (yeah now he has youtube channel and make a lot of new content) on how to design car that looks good but also has a lot of aerodynamics function. I want to know your response, Thank You

I would really like to see you designing the model step by step , Pls make one !

Love the analysis bud, ever thought of creating a community discord?

Reallly nice video. What CAD and CFD softwares you use?

Great and informative analysis and tutorial as always! I'd like to see analysis of these flying car prototypes. Less interesting, but maybe also worth a look, is the low drag coefficient on Teslas and what their secrets might be.

You should reference the TT mr1... I own one. Perfect example where you feel sorry for a full recall. I mean my TT has a considerable chunk of weights securely fastened to the left rear, along with a rear spoiler. At auto barn speed the original TT spun around(160-200kkph)

I remember watching this video when it went live, one of the first I saw of yours Kyle. Absolutely love the intent of the LMH regs, I'm still astonished and disappointed that on Peugeot has decided to go along this route. Quick side question: as the car that was cheekily entered into more le mans that it was really eligible for, how would the Porsche 962 fair for these new HyperCar regs? Would a new engine/hybrid system and a pick of paint be enough to make it able to take part in yet another le mans race it wasn't really designed for?

When the car was shown I was a bit surprised but after thinking about the concept it is quite obvious why they did it. The regulations are limiting the concepts quite much and with a set C_x and C_z I would also go for the diffusor instead of a wing to produce downforce because it is way less sensitive to drag and other conditions. With considering that Peugeot wants to win Le Mans and therefor might accept worse results on other tracks there is also no reason to place a super flat wing on the back. But the exhausts might be just a design for the lounge. They are really weird looking and (without doing a cfd analysis) look like they waste the airflow over the car that should be really efficient without them. One thing I am not sure about is the big height difference between diffusor and top of the rear. There should be so much bad air in between. And usually noone wants that in the rear of the car. Even with the regulations and the need for some drag I don't think it should be there. Nice video! Thanks for the work!

Great!!

Looove your videos. Thank you so much! Ehat cad software do u use? I have a dream of drawing my own car

please make a video on the cad modelling

Very cool and informativ videos but one question which programm ist this? Thank you for ur fast awnser and have a great one

With this "no rear wing" and having the regulations in mind( both examples with the same amount of downforce) you will have more downforce on the dirty air than a car with rear wing or is almost the same? Great video 👍👍👍

Cypertruck aerodynamics analysis would be very interest.

Can you use the CFD to show how to adjust the balance while changing the downforce levels please?

Would you be able to show a tutorial on how you mocked up this concept in CAD? Thank you.

I'd say it's got some inspiration from Ferarri's FXX and FXXK, which neither have rear wings to speak of.

This makes me wonder how many modifications would be necessary to convert any Koenegsegg to the LMDh rules

it looks almost seamless, i wonder how they would go about changing front and rear clips like you can on lmp1 cars

Is the CAD model you created somewhere availabe to download (at least for academic purposes)? :) Great video as always, would love to use a CFD study on this model for my aero students :)

Hi there. Awesome video. Are you going to analyse the aerodynamics of ferrari 499p as well? Unless you have already and I've missed the video...

The car looks marvelous, although if a driver chose to take a curb that would be slightly too high it seems like the race for him would be over at that point since the floor is the main aerodynamic factor on this car.

I keep thinking it's a Porsche, nice video

Video suggestion. Remember that Mastercard Lola car that that no wind tunnel testing and was therefore terrible? I wonder how bad it really was.

Do you think you could either share the model of the car or show how to make a model like it? Also do you think you could share what CFD software you use because I am very interested in CFD and I was looking into learning more about it.

Nice

Don't you think that the position of those exhausts help with downforce at that curve at the back, like how it would be with a blown diffuser?

i´m guessing one reason to why they did this is to stand out, and become something people talks about, while still being able to be competitive

Is there anything in the rules preventing the teams from getting their numbers from an unrealistic configuration? Such as the mentioned high ride height to reduce downforce for the relevant test and then get more downforce in the actual race?

Crazy thing its gonna be a road legar version of that car :O

What cfd and cad software do you use?

Very interesting ! What kind of CAD are you using ? 3 DS ?

Can you make a tutorial for step by step CFD analysis

Does this potentially make the car better at following and overtaking because it is isn't relying on over body aero?

Nissan built a front wheel drive prototype racer a few years back to get better aero and downforce while Peugeot built a wingless car for better styling. Why would Nissan go to such lengths when a wingless car would have been ok? Are the downforce requirements of the current Hypercar class lower than the prototype racers during the year that Nissan FWD racer competed? Edit: commented before watching the vid. The vid answered my question.

You mentioned using some inlets at the lower front corners for possible brake cooling. Would the direction of those internal ducts have a noticeable effect on the aerodynamic performance of the car?

Would a concave design wheel dissipate more brake heat than a regular flat design wheel?

This is funny im also named Kyle and im really interested in aerodynamics
