Then why do not only open the top front aera with vents? Maybe i'm wrong but a think it could suck the hot air before reaching the engine and reduce lift because no aera to lift?

Thank you for doing this video! Do you know or have an idea how much drag could be reduced by rounding the corners? I know it complicates the building process, but I’m always up for a good challenge.

May I ask how you got these simulations with the lines and how the airflow moves around the wing?

Lol, emotional support vehicles.

Perhaps the Brabham Delta wing had an outwash effect?

Nice work, its fantastic to see your design process. Isn't it great how the ROSSA rules are so open you can come up with your own unique way of solving the problem?! I'm also working on a RC speed vehicle with similar goals (albeit in the open class) but my solution is totally different!

Could you do full aerodynamic package of nissan micra K13? I'm curious how it can approve for track racing.

Was nice to listen while eating dinner. xdd

Great video, thanks for sharing your knowledge.

Shit man it's easy put a wing on the bonnet see easy just do it man

do you want to analyze one of my cfd simulations? pinky promise its interesting

Convex trailing surfaces tend to have vorticity attached to them which helps them with streamlining. It's hard to use concave shapes to guide flow, it will look like crap on most cars having U or C shapes on the top body work. Alternatively those convex shapes are flow killers in the underbody.

I was literally staring at the thumbnail like "is A4? or is 3 series?" xD

Nice work

Thank you👍

Hy guy, i from brazil, and i find this models? Please help me most fast posssible, Thanks!

Now if you did 'Hood Ducting' it would make a great benefit.

Potential video idea... The aerodynamic effect of "wind deflectors" on cars (also know as rain deflectors, window guards etc). Manufacturers often claim they 'improve aerodynamics' and 'reduce drag' but I can't find anything online analysing the subject. Please do a video about this I'd really like to know!

what about removing or cutting the rear bumper?

this is hilarious

I am building a Golf Mk2 for race event and this information is very helpful.

Danke brodix

Looks cool, doesn't affect performance to an noticeable extent, without it the loss would be bigger and increases practicallity for daily driving. I'm not a professional but I can say that's a clever idea

So, i have an 05 Honda HR-V and I've always been curious about why they came out with spoilers. Would you be able to look into this model specifically please?

you are my hero

this guys voice really helps to digest this dry and techincal video

The turbulent flow in my brain is provoking soo many eddies that can't be computed😂... Great explanation Phill, appreciate soo much your videos, but I'm just a simple guy, see a video from you and click like, hope some day, I can really lear something usefull to do some simulations in free CFD app of my future racing car project😅

Love how it jumps straight to the point

Very nice, Nelson. I appreciate the effort you went into in order to avoid using "big" and "scary" equations to describe the underlying physics, and went for an approach that would be easier to understand for a wider audience instead. I wouldn't mind seeing more of these videos in the future, though I enjoy your more "practical" videos on automotive aerodynamics as well. Either way, keep up the good work!

Oh wow! Definitely technical, but very informative.

The boundary layer between my brain power and the brain power needed to understand is immense

the flow of these thoughts was turbulent (it went over my head)

bird sam is a bird hugh is a bird it scary

Nice work

Check out the flow structure @ 4:07 behind the rear wheels, in the 'inboard loaded(problematic)' frame. Notice how it's dragging down the rear wing tip wake, swallowing the beam wing tip vortex, and the diffuser corner flow. I think a huge amount of performance is in that region, and that a heavily inboard loaded front wing strengthens the flow structure in the rear wheel because it connects with the upper wheel vortex shed off the front wheel.

yes WRC cars have the spoiler on the rear window

if i ever met Newey I would spend my time with him asking him to critique all the other bad designs of this era. he can probably comment immediately on whats wrong with some cars.

Please do a video showing how you created your model and ran you aerodynamic simulations.

I have an f3000 90b wind tunnel model

anyone know what software he is using?

I am trying to overcome the turbulence around my domestic car, to get a laminar flow of air from front to back. This last year I have been going down the 'Rabbit Hole' in every aspect to achieve this Learning on the effectiveness of a 'Under Tray', the effectiveness of 'Air-Curtains', 'Hood Ducting', 'Separation Edging', Adding a Lower 'Air-Dam' and blocking off the upper part of the grille to improve the aerodynamics and reduce the drag. Not having the Computer Capacity or Finances to research the CFD of my car I like to see if someone can do some tests to see he effectiveness of each of these as well as the effects of a Car-Bra, Bug-Shield, and other Add-Ons for the domestic car market.

What softwares were used for CFD? and what software was used to generate the model on the lazy susan? Nice video!!

What do you think about the factory Honda Civic EP3 TypeR rear wing? I think it's the nicest factory wing on a hatchback ever

Mate, I wish you had a BMW E82 1M to use for all your work :D

I heard from one of noriyara video this mod was used in 70s and 80s cars in japan and i remember the name of it was front jacket or headlight jacket

"do you even lift"

Awesome content. Please do one on front fender vents.

did i understand it correctly (and im realy not sure), that you find out, that a round/smoothed out front is more fuel efficient and more aerodynamic, than this 40 year old chunky car? wow. thats not impressive. i would love to see how you try to improve a model of the hyundai ioniq 6. or at least learn from the already done innovations and add them to your model and see what is changing.

bro left us on a cliffhanger
