Waiting to see the GR86 (and possibly the 86 after the restyling of the front bumper and rear spoiler) 😁
isn't it the same body car?
@@jerosajose the revised 86 has a considerably different front bumper and rear spoiler (more "wingy", I would say). I wonder whether the new bumper addresses the issue found in the video on the old one and the real effectiveness of the rear spoiler (i.e. if it does something or is just aesthetic)
@@YariNebbia oh okay
Thanks for the idea!
Yes! Would LOVE to see the 2nd gen BRZ and GR86 with and without the spoiler
I love how this is a channel about aero, usually a pretty serious topic, mixed with childish jokes. Keep it up! Oh and still waiting for the Jaguar D type ;)
I wonder how aerodynamic is second gen Prius moving at 650 kph
Plenty more where that came from, homie.
Lol. We have that on the list and just need to get around to it atm!
@@PremierAerodynamics
Do you have a Volkswagen GTI on the list? 👀😂
He casually upgraded Subaru's work with the air ramp
This was great-would love to see the second generation cars too.
Thanks for the idea!
@@PremierAerodynamicsplease compare with and without the ducktail spoiler. I installed one and felt that the rear was significantly more settled.
Now you mention GTR , i am curious about it . I remember back in national geographic channel the nissan people are really proud how boxy the car is intentionally made while working on aero , saying not every car needs to be fludic & smooth like 458 to work on track .
The my24 gtr make 0.026 cd and make front and rear downforce especially the nismo. The nismo gtr don't increase drag but its increase downforce
I have always thought the protruding nose of the R34 GTR was a restyle of a early Volvo P2 series.
@@improvedae86 I meant the R35 gen by the way
Thanks for the idea! We have it on the list.
Can you compare it with the gt86 to see how different front bumpers affect the car and also facelift gt86 bumper with the facelift spoiler
Thanks for the idea! We'll see if we can get a good model of it.
I’m surprised how little car aerodynamics channels there are. I’m glad to see one. That’s so entertaining and put out a lot of helpful information. very curious about the Alfa Romeo Giulia thoe
Thanks for the idea! We have some Alfas on the list.
i'd love to see the new 2024 updated Mazda MX-5
i would like to know how well behaves the roof of the car, as it is so short and the windshield is so steep, but they still put a little spoiler at the trunk so that means the flow keeps attached til the end?? pretty weird
Thanks for the idea! We have it on the list!
Id be curious as to the effectiveness of the small rear wing on the top end 86/brz models
Thanks for the idea! We are thinking about doing that too.
This is super important to see as an 86 owner who wants to get a bodykit
Definitely
If you could do one on the new Iconic SP concept car, I think it would be really interesting.
Thanks for the idea!
@@PremierAerodynamics Of course, would love to see it! 🙏
I love your videos and the acessable way to learn stuff about car aero. My Porsche 987 Cayman starts lifting quite noticably on the Autobahn; would be really interesting to see the reasons for that (besides that its a big wing^^). ...and I think aero analysing porsches might help get new people onto the chanel. Imagine the clicks on a 992 Gt3 RS-video. Thanks for all the learnings so far. :)
Thanks for the idea! We have a bunch of Porsches coming. The Cayman is a sweet looking car.
Hot dog?! 😂 I was expecting Mickey Mouse on the next slide, cool video.
Next time!
Appriciate the time for making such good video! Next question is where to find those air ramp on the aftermarket?
Thanks!
We don't actually have their manufacturing sorted out at the moment. If you like, you can give us an email (our email address is in our bio) and we can email you once we do have it sorted out?
loving the content, awesome as always. I know i asked already and you've said its on its way, but when you do the 3rd gen firebirds you should look into all the different body trims (i.e. Firehawk, GTA, and just base Firebird, they had different rims, wings, hoods, etc.) and some of the "turbo" cowl hoods were functional and acted as a air intake under full throttle, idk how that would effect air separation at the hood/windshield merge. Probably would have a seeable change since most of the cars that had then were 5L engines, that's a lot of air it can move.
Thanks, we'll see what models we can get hold of.
Please do one for the Iconic SP Concept!
We'll check it out!
"the car doesn't go that fast anyway" 💀
This is great!! I'd love to see how the 2ns gen BRZ compares, they did flatten the rear window, and there is a small air ramp. Thanks for the amazing videos.
Thanks for the idea! Okay, I haven't seen much of the new one yet.
@@PremierAerodynamics If it helps I have one in my yard. Subjectively lots more drag and downforce than the 1st gen. I've been looking all over for real data on it but the only thing I found was a clip of Subaru doing wind tunnel testing.
can you please do a series on gt3 race cars? it would be rlly educating to see which manufacturer has the best aero on their car :)
Nice one
Thanks for the idea! We actually just arranged to get a few models the other day. So, they're on the list.
Thanks for the video, I have a 2014 so this was really interesting
Glad you liked it!
Amazing content !
Appreciate it!
I pressed like! and requesting for GR86!
Thanks! And thanks for the idea!
I would love to see the new GR update compared to this.
Thanks for the idea!
🔥 make a q50 video🧎
Thanks for the idea! We'll get started on it. It may take a few weeks to run the simulation and make the video. So, stay tuned.
That Air Dam improvement was impressive, I wonder how aftermarket front lips affect the aero, they could add some small gains ot the other way around...
I'm guessing most of the lips I've seen will increase drag, especially if they're not true splitters. That little bit about rounding the leading edge of that splitter has me rethinking how I'll do mine, and I'm glad!
I think aftermarket air dams would work better because aftermarket splitters would have to be really long to have an effect because the car is quite far off the ground.
Nissan GTR R35 please.
We have it on the list!
Gotta do the S2000! The rear bumper creates a massive parachute under the car
Thanks for the idea!
Now I'm curious what changes on the face-lifted version with the tiny wing
Thanks for the idea!
Thank so much for this video I own frs and brz
Thanks!
Awesome video! It would be cool to see as many have mentioned the inclusion of the ducktail or other spoilers to the rear. I can see in your links the resources to go learn Openfoam which this has given me a kick for, esp when wanting to design my own parts for my 86 for time attack purposes, and this air ramp has given me something to ponder alot instead of working (thank you!)
Can i ask, do you source models/meshes online, do you generate your own? If someone wanted to learn how to do this sort of iterative testing with openfoam what would the complexity rating be?
Lol, happy that you've got something to get you out of work.
Can you make about Proton Waja? That sedan unexpectedly have such an excellent stability on corners
Thanks for the idea!
@PremierAerodynamics aye welcome! For a reference I drove Honda City and a lot of cars too, but Waja is arguably top 3 best handling that I ever drove, the other 2 that surpass it is an expensive car a Mercedes E class and Mazda CX-30
First time to your channel great vid… love the fact your tested an improvement mod.
Are you suggesting no rear wing is best?
For this car, a rear wing mounted at least 20 cm above the trunk would work. Below that, it would be really inefficient.
@@PremierAerodynamics I'm from the EU and here the car comes with a little "air fighter" styled wing. I’ve changed it to a ducktail and my butt says the car feels more planted but that could be buyers bias or maybe drag that just feels different?
Would love to see the new Prius
Thanks for the idea!
Hey I’m an aerospace engineering student, and would want to do such an analysis on my car (GR86 with a ducktail), but I’m wondering where do you get those 3d models?
Would love to see the FL5 Civic Type R
Thanks for the idea!
I wanna see a st185 Celica test but good luck finding a model to work with
Thanks for the idea! We'll see what we can get.
Do a gr yaris next pls :)
Thanks for the idea!
hey i like how you explain aerodynamics and i wonder if you could make a video about a car from a game ''BeamNG drive'' its not a real car but it is quite realistically designed, its called ''Civetta Scintilla''
Thanks for the idea! We'll look into it!
I can almost smell the RX-8 coming from here. It'll happen, surely ;P
Thanks for the idea, but I don't think that's the RX-8 you're smelling...
@@PremierAerodynamics I feel like you just gave a hint as to what the next car will be, and even though it's not an 8, i definitely won't complain ;)
Or you called me stinky. Either way, well said lol.
Lol, it was just a play on words.
do the 2015 Mitsubishi ASX/Outlander Sport please!
Thanks for the idea!
Great!
Where did you get the 3D model?
hi back again to suggest the 85-92 irocz camaro, i also wanted to know where you guys got your car models from
We have it on the list and just got hold of a model the other day. We often need to make them, or get other people to make them.
Chevy Corvette next please
Thanks for the idea! We have some version on the list!
Please discuss the aroeodynamics of the Peugeot 206rc ;-)
Thanks for the idea!
It would be awesome to compare it to a similar weight and power hatchback. 2013 Fiesta ST, maybe? 😊
More drag and lift, I guess?
Thanks for the idea!
Now I really wonder how this compares to the late 94-99 Celica because these are very similar shapes
Thanks for the idea! We have that one on the list!
Next, the OG aero champion -- G1 insight!
It's also very short, even shorter than the 86. How it overcomes the length problem and still achieves 0.25 Cd could be worth a chat
Thanks for the idea!
I usually watch Kyle Engineers videos but its really nice to see road cars for once! That said, I'd love to see an 09 370z ST analysed ;) Either way, looking forward to the next car !
Thanks for the idea! Kyle is a good watch.
Could you do Mazda Miata Mx5 to see how their jinba ittai design philosophy impacts aerodynamics?
Thanks for the idea!
Im curious to see the Toyota Celica gt-four st-205. Mainly to see what is happening over the bonnet as when driving in the rain at 100km/h the water is flowing to the front of the car. I guess the airflow may be detached
Cool! We might have to look into it!
Analysis sugestion: Opel Calibra
It's said it has the lowest CD ever achieved by a mass produced car.
Peace, amigo!
Thanks for the idea, amigo!
You know, I'd be extremely curious to know what this all means from the perspective of a hobbyist looking to upgrade their car. With the rear window being a sore point, would vortex generators help? What about an aftermarket diffuser or small mods one could reasonably do?
If you have a rear wing very low down, then vortex generators would help get faster moving flow there.
How much better is the ge2 BRZ/GR86 since subaru and toyota claim a lot of improvements?
Thanks for the idea!
Do the GR supra!
Thanks for the idea! We have it on the list!
Loving this channel. Would love to see an aero Analysis of the no windshield Aventador J concept from 2012
Thanks for the idea! We'll look into it.
Not sure its just me being dumb but the way you seem to classify stability seems a bit odd to me.
I would have thought having loads of downforce near the back and not much at the front would be "stable" as the car would want to keep going straight. It would be terrible for high speed agility/turning, but good for high speed stability. Whereas it seems youre saying downforce over the front js good for stability, regardless of the rear. But surely down force on the front with little on the rear would make the front very twitchy and the back floaty, which to me sounds like poor stability.
Good question. The answer depends on a few things.
The first is that most cars produce more downforce at the rear than the front because of the general shape and diffuser. That leads to potential understeer during corners. Having a more balanced downforce production makes it more stable.
As for straight line speed, it depends on where the power is coming from. If you have a rear wheel drive car, then more downforce over the rear wheels helps you put the power down and go faster. If you have a front wheel drive car, then downforce over the front helps do that. All wheel drive generally has a pretty even split, with perhaps a little more on the rear wheels.
The more downforce over the driving wheels, the more grip, and the faster you can go.
How about an ND Miata?? Would love to see the aerodynamics of a convertible, my back window never gets dry after a car wash, and driving in the highway!
Thanks for the idea! We have it on the list!
May I ask how do you get the model for the CFD? I’m planning to buy some existing 3D models and somehow recreate a fully enclosed solid model.
We often get people to make them, or modify them ourselves.
greag run down, waiting for a Gd sti :)
should be an interesting one especially comparing 04/05 vs an 06/07 with the rear roof vane
Thanks for the idea!
I've been hoping that someone would make this video for years at this point! Verus has their pictures, but to have someone talk it though is super helpful. Also, where is the air ramp in the model/what should it look like? Am curious how this might impact real world handling.
It's a gentle bump on the underside just after the front lip/splitter. It adds downforce to the front of the car. That helps reduce understeer.
Can we get a q50 aero analysis?
Thanks for the idea!
@@PremierAerodynamics was trying to send 5-10 USD for the idea like a super chat or something, anyway to send a one time payment for that sort of thing?
Thank you so much. I think if you go to one of our videos, like this one of the BRZ: ua-cam.com/video/j70r4qDRLfU/v-deo.html and then just below the video to the right, you see a few different buttons. Click the three dots, then there should be an option that says "thanks". If you click that, then you should be able to.
Thank you once again and we're really happy you like our videos.
curious about the air ramp youve added, would it be the same for the GT86? since the bumpers are sightly different, could you possibly do a video of the GT86?
You'd get a similar downforce effect. We have the GT86 on the list!
@@PremierAerodynamics awesome thank you for the reply, as for the air ramp you designed have you got a model of what it would actually look like on the car for it to be replicated on a real car?
Yep, we have the design.
pls do the mazda rx7 fc3s savanna infini turbo
Thanks for the idea!
Would love to see a video of the new GR86 and BRZ with and without the ducktail spoiler.
Thanks for the ideas!
It would be really cool to see an acura tsx 04-08, they seem pretty sleek and I always wondered where it could be improved.
Thanks for the idea!
You should make a video comparing the same vehicle against itself at different ride heights, as many performance (and riced) vehicles have coilovers or are otherwise used with lowered suspensions.
Thanks for the great idea!
Make a video about the schlörwagen
Thanks for the idea!
Do smth TERRIBLE like an exomotive exocet it look so cool but the aero must be so dang bad
Thanks for the idea!
This is some really interesting content. Recently I got more interested in car aerodynamics (I'm just a casual car fan without engereering background though), so videos help me understand things a bit more deeply. Since Mercedes Benz is well known for their aerodynamics and low drag coefficiencies, I do wonder how they achieve and if whether or not this come with caveats. Especially cars like CLA and EQS are pretty strong in their drag coefficiencies.
Edit: Just saw that you have a video about the EQS. Amazing!
Thanks for the idea!
Just a quick note on mercedes, they usually pinch the rear a lot to reduce the drag. That's a huge advantage.
Can you do a Miata? Either one is the generation would be fun. As we can see the different between open top and close top in a small tiny car. Please 🥺
Thanks for the idea! We have it on the list!
I had one of these, and the wind noise when opening the windows was unbearable, there was some kind of turbulence.
Wow, that is probably because of the A pillars. In the video, you can see just how large the vortices coming off them are.
I would love to see how a 8th gen Civic SI coupe would look! I havent seen any CFDs on them 🧐
Thanks for the idea! We have the Civic on the list!
Plz do the Miata, one for the soft top and one for the hard top
Thanks for the idea!
So gen2 simulation soon?
Thanks for the idea! We'll put it on the list. (I actually didn't know the second gen was out...lol)
Could you please do a ND mx5 RF in comparison of the soft top?
Thanks for the idea! We have it on the list!
Make video about w124 please
Thanks for the idea! We have it on the list.
Would be eager to see how the 2022 BRZ does compared to its older brother
Thanks for the idea!
can you do a comparision between the old gen and the new gen brz?
Thanks for the idea!
do you have a link where I can purchase your air ramp? that would be cool
Thanks! We don't, but if you like, you can give us an email (our email address is in our bio) and we can email you when we sort it out?
can u do the e46 330ci compared to the same gen m3
Thanks for the idea! We'll look into it.
to me it seems like they barely did any aero testing of this car, if just a simple air dam improved the downforce and drag that much
Their drag was pretty good for a car around then, but I think styling took precedence and aero took a backseat overall.
Hello, awesome video as always, could you maybe include previous cars in the Downforce/Lift table or maybe export the table/info to google docs or excel and leave a link in description? I am very curious to see how Valkyrie, LaFerrari, Koenigsegg and several others perform in this area.
Thanks for the idea! We'll see what we can do with the google doc.
Please do the ND miata RF 🙏🏻🙏🏻
Thanks for the idea!
Can you do the legendary Lexus LS400? As far as I know it has a pretty advanced aero for the time with a low .26 cd coefficient. The Skyline GT-R R34 V-Spec II would also be interesting imho.
Thanks for the ideas! We have them both on the list!
@@PremierAerodynamics Awesome, another request I have is a niche product but I drive one so, naturally, I am very interested to learn whether the fuel efficiency (the drag) can be improved on my vehicle. I drive a 2013 Lexus GS450h F Sport. I am curius if the drag would be improved if I cover the brake cooling ducts on the front bumper. Would be happy to help you with measurements and pictures for this one
I have a non-related question: in a hypothetical longitudinal rear-mid engined car, can you generate 500kg of downforce without a wing, so it would give space to a rear trunk in the place of the rear wing?
well i guess with a good enough ground-effect underbody 500kg is achievable
People really underestimate the underbody work. It is theoretically capable of higher downforce compared to the wing and will still do so with less drag. Unfortunately that needs a low ride height and stable roads so slapping on a wing is the popular choice. And wings provide more consistent df. Theoretically, aggressive under bodywork and a small spoiler can make a really good amount of df with very small amount of drag.
@@hrishikeshaggrawal I mean, luckly nowadays we have active suspension, so we can have high downforce when we need and high ride height when there're obstacles in our way, like a ramp or a bump.
@@leomux2004 no, its not good enough to make a difference. Just look at Peugeot's endurance hypercar, they went from no wing to having one. Their though process was that since race tracks are generally more flatter compared to normal roads, underbody based downforce would work, but even just smooth undulations ruin the airflow enough to cut all df
@@hrishikeshaggrawal Nope, after they added a wing, their car got slower, they were better WITHOUT a wing.
still waiting for the volvo v70 2nd gen and also the spoiler that they installed for R version how does it affect drag and downforce
Thanks for the idea!
Would be curious to see comparison between a 992 gt3 and a 992 gt3 touring
Thanks for the idea!
@@PremierAerodynamics thanks for your videos!
Could you do the Hyundai Staria? 80's wedge supercar front on what is essentially a sideways apartment building could be interesting.
Thanks for the idea!
@@PremierAerodynamics Oh man I am full of ideas, just lack the training, skill, knowhow and resources to test any of them. Like an actual CFD analysis of golf ball surfaces for vehicle aero where boundary layer separation is actually important. Another one would be the whole TVR Sagaris fender situation where they actually designed louvres to extract wheel well pressure but for some reason never actually opened the holes and left a "shark skin" surface... which leads back to the golf ball idea where what if a vehicle was covered in a shark skin surface like 200,000 tiny little Kammbacks? Some nights I think myself to sleep trying to resolve the issues of CVT gearboxes by imagining conical friction surfaces that could act like cones of sandpaper... Yes I'm fun at parties.
What software do you use for this kinds of stuff?
OpenFOAM.
We do courses to teach people how to use it in the link in the description, if you're interesting.
Thank you for helpful videos.
I would be grateful if you could feature
A90 Supra or,FD RX-7 with spoiler(Model:1999～≒Spirit R).
Thanks for the idea!
Can you do smart roadster coupe?
Thanks for the idea!
Do the Lucid Air pls
Thanks for the idea!
Can you do a honda fit
Thanks for the idea!
Fact :- subaru BRZ , Toyota GR 86 , Scion FR-S are same cars .
Small changes in suspension balance and interior trim but otherwise the same
First gen: BRZ, FRS, 86/GT86
Second gen: BRZ, GR86
And I remember back when it was released that the deal was that Subaru could only sell like 10% of the cars Toyota could. So, even though they were basically the same, there was a premium on the subarus because they were rarer. Not sure how long that lasted though.
@@PremierAerodynamics oh that's interesting 🤔
Can you do the Mazda Rx8?
Thanks for the idea!
can we get lotus elise series 1 vs series 2?
Thanks for the idea!
Time to 3D print an air ramp to put on my BRZ :D
Lol! Would be a cool idea!
There are way to reduce the drag on the frs flat underbody verus engineering has those , apr mirror smaller , rear diffuser, varus engineering , cut the rear bumper is important , air dam
Definitely. This car doesn't have much of an aero focus, other than general drag reduction. So, there are a lot of things that would work.
@PremierAerodynamics lve been thinking about this alot and not really quite sure if it will work semi trailer tire and wheel creat drag what If I build a larg wind deflectors like formula E would it work
Can you do the rx8?
Thanks for the idea! We have it on the list!
How long is the car list now?
