Enjoy the analysis everyone! For all my time attack viewers I'll be around the pits at World Time Attack Challenge Friday and Saturday so feel free to say hi!

[@ChevroletastragtcOPC]

Kyle i got a question i always wanted an answer, what kind of role weight takes in case of a crash. I mean the same car at the same crash speed but with a 200kg difference or/and different segment cars. I was arguing with a family member about this i said that even if a car is small/lightweight if it got a good safety equipment that will be the car to be in case of a crash and not a heavy SUV. Can you bring some light to the dark??

[@KYLEENGINEERS]

Hi Mar, depends on the crash, if you're crashing into another car you want to be heavier as then you will have more momentum than them and you will decelerate less (at the cost of them decelerating more/reversing their direction of travel). If it's just you crashing into a wall or tree, you would be better off with the car with better safety equipment.

[@Y3ll0wSoda]

KYLE.ENGINEERS if you did a video on the new Honda Civic Type-R's aerodynamics that would be awesome! Honda claims the body of the car is aerodynamically functional. would love to see your analysis on their claims.

[@Marco-nx5tj]

KYLE.ENGINEERS hey y don't you make a toy car that can glide

[@rallydrew]

I'm curious as hell about how the Ferrari FXX K little rear spoiler ends function if you could video analyze it for me, thanks! Just a suggestion.

[@paulbalamon2298]

I think you have found your niche in the youtube car sphere!! You should make Aero Analysis a playlist!! could you please analyse the regera

[@benwilson5724]

have you seen the new regera spec back end

[@willchen9014]

That is the most impressive underbody I have ever seen. Shows what can be achieved when aero isn't restricted by loads of regulations. I would love to know how it compares to current F1 cars in terms of downforce.

[@F1ll1nTh3Blanks]

The track version would beat F1 cars on certain tracks. That's my guess.

[@xavierrodriguez2463]

@@F1ll1nTh3Blanks only 3gs in the corners for the track version, impressive for a road car but the short wheel base and extra mass needed to make it more road usable kinda fucked it performance wise.

[@valkeitos]

@@F1ll1nTh3Blanks you underestimate F1 cars significantly

[@lucywucyyy]

im real hyped on this thing, i wasnt expecting it go go any farther than an idea so im glad to see they are actually expanding on it. it will be real nice to see a hyper car where the aerodynamics team has gotten significant priority over the aesthetics team. and honestly it looks even cooler now that its more aerodynamic. i hope this thing actually gets made.

[@BeyReaper]

I too like how the Aerodynamics team got control over the car more than the design team. tbh the car look very beutiful so i cant really complain.

[@lucywucyyy]

as long as i can play with it in video games il be satisfied lol

[@jbman890]

antsolja what are you guys talking about? There're 125 being built and all the owners already have heir order, infact a real one has already been built and shown to the future owners.

Hey Kyle, aerodynamics are starting to get relevant on motogp bikes this year. Can you make a video explaining the benefits? thanks!

[@afrog2666]

Valkyrie "update" is more like a completely different car.. Most of the key features apart from the general outline have been significantly changed. It`s basically a new design..

[@popeyeisgood]

would be nice to see you do another video of the latest prototype. very interesting analysis on the aero.

[@clubsport9334]

Subbed. Easily grasped info on a techo subject!

[@ordguy]

Love your videos. Now that the Valkyrie is finally being delivered (a number of differences from the old photos here) and since there is also an AMR Pro version, can you do a Valkyrie and Valkyrie AMR pro video?

[@nathanzhou9662]

The man added bargeboards and Y250 vortices to a road car. Neat.

[@eedesign878]

Good one. Interesting stuff.

[@DoctorGoFast]

Great video as usual. One question came up in my head. In case of loss of control during high speed cornering situation, could the car be thrown into the air due to not having a shark fin like structure and wheel openings like and LMP1 car? Keep up the good work and the great videos

[@cliffordbradford8910]

good point. It wouldn't be good if the thing backflipped at 200+ mph. Maybe that's part of the reason for venting the frin more and cutting away the area behind the rear tire.

[@DoctorGoFast]

Could be yeah. Still if the car is going against a wall of air at a 90 degree angle I would imagine that there could be a high pressure build up on one side of the car. Can't wrap my brain around that. Still this can all be a dumb idea on my side. Don't have the proper knowledge of aero like Kyle has.

[@christianponicki9581]

I doubt that'd be an issue; sportscars have gone decades without fins, and they had no problems like that, to my knowledge. The benefit of the fin seems so marginal that I wonder if it'd even be on most prototypes if it wasn't mandatory. The only major stability problem prototypes have continuously suffered from is backflips, which are caused by the mandated flat(ish) undertray. However, this car has enormous ground effect tunnels, so I doubt it'd ever experience flips.

[@EG3HC]

Chinese billionaires seem to have no problem crashing their hypercars in cities let alone at Vmax speeds...

[@SM-ll3hf]

Thanks a lot, this is gold. Thanks

[@jamesdenney9653]

Thanks for clarifying the effects behind the rear wheels. At first glance I'm thinking there's going to be a low pressure zone there that greats drag, kind of like the magic levitating screwdriver trick that uses a jet of compressed air.

[@jurandspychow3766]

Love your videos ! Could you please make an aerodynamic analysis of the VGT SRT Tomahawk X ? Mainly, because it has a very interesting aerodynamic flaps system. And its mental.

[@corsamc12]

Thank you so much for the excellent video! It addresses some of the questions I had for a long time. However there is one more thing I couldn’t understand, why the Valkyrie and so many sports cars recently choose to leave the back side of the rear tire completely open, instead of having some elements to manage the rear tire wake?

[@SQTOS]

These are the videos !!!!

[@gabrielwillames]

nice to know!thx

[@justinjohnson1766]

Thanks man.

[@epstar83]

Interesting videos! Would you ever consider doing a video about the Thrust SSC that broke the land speed record?

[@lordchiang]

this is impressive,let's see the gearbox can be how slim.will you do a video about the chinese NIO EP9?

[@JakobusVdL]

Thanks Kyle, great analysis and explainations. With the wheels being mostly covered, and the huge diffusers, will the downforce generated by the car be more consistent than a wings and open wheel F1 car? It doesn't appear to have the multiple winglets, tabs and slots that F1 cars have on their wing and barge board, what are the reasons such details aren't provided (or required)? And are there any estimates of the amounts of downforce this car will be able to generate? What sort of tyres will the Valkyrie run? Presumably something pretty special to be able to cope with the power, the speed, and presumably significant downforce.

[@KompletterGeist]

Hello Kyle. Love the video, very illustrative. However, I disagree strongly at some points! Let me elaborate: At 12:21 you are speaking about a vortex that builds up underneath that outward footplate. Now from my experience as an aero engineer in formula student I can guarantee you that this is not the case whatsoever. The air will just flow underneath that plate and build up a vortex on the edge of the diffusor-fence. The purpose of that plate, if you run it low to the ground, is to create a kind of gap seal. When the air is flowing through the tight space between the plate and the street it loses energy which will result in a smaller vortex compared to a diffusor without such a footplate. Another point I disagree with is that you said at 12:00 there is a HP behind the tire and a LP in the diffusor. That is also not the case. Directly behind the tire there is a low pressure region and since we are at the exit of the diffusor, the pressure won't be that low at that point. The thing that is probably forming the big vortex you talk about is very likely going to be the rear tire jet that is being sucked underneath the diffusor I am also a bit iffy on the front wheel plate with the outwards slope. I'm pretty confident that if this plate creates suction in any form, all that is going to be sucked is the front tire jet. I don't think it will increase the frontwing performance Ofc I could be wrong and I'm not as educated on aero as you but we run such an outward footplate on our diffusor and the vortex never formed underneath that plate no matter the ground clearance or size of that plate

[@KYLEENGINEERS]

Hi there, the vortex at 12:21 is something I have seen in practice with some of my large tunnel/diffuser, high lateral expansion designs on touring car bodies, so I can assure you it exists in quite a few cases. I have also previously discussed this diffuser footplate vortex with my old PhD supervisor (ex F1), and he has confirmed its existence (in fact he was the one that first put me onto it!). Regarding the HP/LP, again on the same designs mentioned previously, with high rear lateral expansion there is about a 0.5Cp differential between the outside and inside of the diffuser as we move towards the rear of the diffuser where the lateral expansion is forcing against the tyre wake. At exactly the rearmost point of the rear tyre, they are about even in pressure (which does extend back a little), and at the front and mid of the tyre the pressure is higher outside the diffuser body. The fundamental point I was making was that not specifically at the point directly behind the rear tyre, but more along the majority of the diffuser the pressure is higher outside than in, hence the air will flow inwards. And regarding the plate increasing the front wing performance, again it is something that commonly improves performance in more closed body, touring cars, as the more air you can evacuate from the front the better. They have opened the front up a lot compared to the previous model, but there is little doubt that having a vane guiding the tyre wake out will provide a clearer air path for extraction out from the front wing and will consequently improve performance. Take a look at something like the LYFE motorsports GTR for example. Thanks for watching! Out of interest, which FS Team are you from?

[@KompletterGeist]

Thanks for the answer! Well I suppose if you've seen such a vortex in practice then there is no doubt about its existence. Keep an eye on your inbox, I wanna write you a PM about that when I have time tomorrow :) Greetings from Germany

[@alexspizman2136]

KYLE.ENGINEERS you should do a video talking about the aerodynamics of the Chaparral 2J

[@rcnumbers3562]

The 2J had a lot of downforce but it didnt achieve this by using wings but because of a snowmobile engine in the back. That 2nd engine was sucking all the air underneath the car creating a lot of downforce and massive ground effect. Unlike wings this car's downforce was permanent. You know those GPS and Phone holders that you put on your car's windscreen? The vaccuum makes it so it sticks really well to the windshield. Ground effect also did the same thing. By removing the air underneath the car it created almost full vaccuum causing it to stick to the road really well.

[@fcs203]

Can you do a comparison video of AMG one and Aston Martin aero and determine what car will produce more down force and hence will be faster in your opinion?

[@srinitaaigaura]

The first model of the car was purely concept. I wasn't convinced at first there was any space for the engine and couldn't see any intakes anywhere. But it's evolving. Hopefully when it's done it will have a stellar paint job. I wonder how Adrian and Aston Martin are planning to keep the weight down with a hybrid powertrain.... time will tell. I wonder why no one has tried Fan assisted downforce till date. Will that lateral expansion in the diffuser is going to act like a rudder and keep the car very stable?

[@martijnschrama6779]

srinitaaigaura i guess you played too much gran turismo 🤗. I guess it would be very heavy🙁

[@jbman890]

srinitaaigaura it weighs 1030kg

[@srinitaaigaura]

There're homologation requirements that might cause this to go up. Racing designers always start with something inspired from the track, but when they have to bring it to the road, I've never seen a single instance where they actually managed to maintain their ambitious weight target. Still, the difference will not be much. But in terms of aero, this car is a whole other level of crazy. All other hypercars (and even the megacars) won't be able to touch it if they can pull it off.

[@ALPHARHYTHM0]

I believe the Ferrari 599xx had fans in the trunk pulling air from the underbody. I don't know how much it helped aero though. Check out out!

[@pranshupant1413]

Why isn't the throat of the diffuser tunnels closer to the ground on this car? Wouldn't we be able to extract more downforce by running it closer to the ground, thereby making better use of the ground effect? I have seen several diffusers especially in Formula SAE having no more than 3-4 inches of ground clearance and they seem to work quite efficiently. What are your thoughts on this

[@n0ch91c3s]

At the end you talk about the air at the rear of the car going down and in, slipping under the diffuser wall. Wouldn't the wake from the spinning rear tire prevent the downward air movement there?

[@TheBlackopsbeast360]

The original looks quite a bit prettier but I’d say I’d rather have a faster car than prettier

[@julesvereijken188]

Amazing video! But I still don't understand how they get the rear suspension this high up with current diffuser design 🤔. Is there an explanation for this? Greetings from the Netherlands!

[@Darion350]

If I had to guess, the center differential is mounted higher than normal with telescoping half-shafts to each wheel to prevent them from being pushed outwards during suspension travel. The suspension must be pretty interesting, too.

[@matejzrncik7879]

I was wondering, how does the rear radiator gets a clean air if there's huge amount of air extracted from the front wheel and front part of the underbody, almost in front of it ? If I look at it with my basic knowledge, I would assume that air from that big gap at 6:21 would push any clean air that goes around the side of the car outwards and therefore there would't be any high pressure air left for the side radiator. I would love to know how the air around that side of the car really works.

[@jacobkim3213]

Hi, can you do an analysis of the Lamborghini terzo millennio? The car looks awesome

[@saoz3]

most of that was styling, although it does have some similarities to this

[@euanbrownlie9093]

Did you spot the potential rear end cooling ducts behind the rear lights of the new design?

[@ckcoolic]

Isn’t the large vortex in the tunnel how the Eagle BLAT worked? This car seems to have a similar strategy to me.

[@luccadornellas5042]

What do you think about the Delage D12 and the Czinger 21C?

[@deadlyphoenix83]

So where is the rear axle and diff?

[@charleslamb4896]

Hey, what's the most aerodynamic shape? Everyone says it's a tear drop as water follows the path of least resistance but surely the viscosity of water interferes with this??

[@streameant]

are there any active aeros

[@danielberry777]

Wouldn't they want to vent the top of the rear wheel wells?

[@zahidarifi7848]

Can you do a vid between a the closest car that you think is like an f1 car aerodynamics analysis and put it up against an f1 car

[@j.orzech1109]

pls aero analyze the five factory gtm car!!!

[@Phos9]

Have you seen the formula X from project cars 2?

[@lucywucyyy]

imagine if a hypercar could get made entirely for performance with no aesthetics in mind like how most race cars are made.

[@fokjohnpainkiller]

antsolja The biggest concern are the safety regulations.

[@cyjan3k823]

antsolja race cars arent make like that I think There are rules that define how car looks

[@Hampus3313]

Not just safety regulations, you got regulations overall in order to be able to make it street legal. there will always be some compromize.

[@eedesign878]

This is way better than most of the entry or even mid level racecars. Only Lemans and F1 cars are better than this and they have also more drag than this. What would you change? Maybe add big wing only?

[@lucywucyyy]

of course it would still have to obey laws and rules i just mean pretty much all hypercars and supercars i can think of make sacrifices in performance for looks, even very performance oriented cars like the P1

[@Gjaeralaus]

Ok, I have a real oddball request/question: Would there be anything to gain if you took all of your radiators and put them in the back in order to try achieve an meredith effect (as on the P-51 Mustang)? Ignore added weight.

[@Phos9]

Gjaeralaus it’s not clear if this is true, but there’s been a bit of speculation that F1 cars have been doing this for a bit. Theory on F1 technical seems to be that they set up the ducting to accomplish this so long as it doesn’t interfere with generating downforce, and is a bit of a marginal optimization.

[@Gjaeralaus]

Interesting, thx for sharing :)

[@kaymaurischat8697]

The reality will maybe show how handle ground waves or dirty air , or just always to fast ? What will be the acoustic with different engines or compared to a more streamy Koenigsegg ? I would for sure drive it fast on some road conditions, if would afford one 😅 of ??

[@srinitaaigaura]

6.5 L NA revving to 11,000 rpm with a 12 to one exhaust system, it's going to scream like an old F1 car.

[@DoriFord]

If you noticed, the actual idea behind this project for Aston is to create low aerodynamic drag. So they didn't want to sacrifice drag in terms of downforce, thus actual downforce will be very low on the car if compared with a race car, but normal maybe higher than average for a road car. This car has no ground effect whatsoever, just Bernoulli's equation low pressure region and basic idea of less stuff getting in the way.

[@matthias18]

DoriFord so you think it will be for top speed ? maybe 400+ kmh ?

[@stardustb390]

Am I the only one who liked the older design more? it definitely looked more badass with shiny metallic grey/black rims mix, now it looks like a toy :(

[@Byrnzyy]

Why has it not got slicks on if its not roadlegal, or is it?

[@E9X330]

It is

[@jonienglish3231]

YOU FORGOT TO mention !!!!!!!!!!!!! AT WHAT SPEED DOES ALL THIS AERO take into EFFECT ?????????????????????????????????? if you stuck in Traffic just Doing 60 kph is this Aero working ?` or it just Works at 200 kph ~~~~~~~~~

[@BeyReaper]

Aston Martinis going to have to change the mirror situation on that car if they want it to be streel legal in the US. Tesla had somthing like that in their first car but they had to put standard side mirrors to make it street legal.

[@admkbldwn]

Not necessarily. Legalizing camera systems for side view has been under consideration for a while now, and could become reality within the next couple years with pressure from the auto industry. Even at this stage, the Valkyrie is still probably 2+ years away from launch.

[@mathewbsaenz]

What's funny is if it were the 90's, Aston Martin probably would've just released the first version by now. It would've been horrible aerodynamically but would still be praised because Aston Martin and simple 90's consumerism went hand in hand.

[@josephadam1]

I kinda like the original side profile more

[@hitta750]

How tf do you fit a v12 in that!?

[@SteezeN]

F1 cars had v12’s

[@cyjan3k823]

The question is Will it be better than Mercedes

[@m93sek]

As he mentioned in the mercedes video they have different focuses. Mercedes: drive train. Aston: Aero

[@srinitaaigaura]

Mercedes is using a tiny F1 1.6 L V6 with MGU-H and ERS with 4WD electric motors. This car is using a 6.5 L NA V12! Kind of shocking isn't it? Rimac is going to provide an ERS battery System (yeah, the same guys who built the Concept one and the Koenigsegg Regera's battery system). While the Mercedes engine needs a rebuild ever so often, the AM's will last forever. The Aero on this is in a whole other category of insane. It will destroy every other car on a track.

[@0ExG0]

The question is: what will the Ferrar and porche response to this will be.

[@GreatistheWorld]

Yes

[@jbman890]

Krzysztof Dolecki it'll set faster lap times but the project one has more raw straight line acceleration

[@sanjaysekar2903]

[@bjoe385]

I think it will be nearly as fast as a lmp1 car

[@neilmchardy9061]

[@streameant]

wtf is tyre jetting?

[@mdh00000]

Hi great videos thanks for taking time to make them, one request :) you did video about flat floor so can you make video of ground effect floor on same car model? I mean that center of floor is elliptical making reverse wing under the car. Will it work without side skirts sliders? like these : www.formula1-dictionary.net/Images/ground_effect_side_skirts_slider.png Will it make more drag in low and medium speeds? Thanks in advance for yours answer and analysis...

[@SLO722]

[@leksasdf]

They should put turbofans on this instead of the completely closed wheels.

[@tonytutone2003]

You do know they are 2 different cars right? Left is the Valhalla. Right is the Valkerie. Big price difference.

[@HannesHeuer]

As a German I ask myself how this will be legal everytime I see a valkery because our laws and the tüv are very very restrictive

[@sylvesterfranklin2686]

It's crazy that I had this idea and designed this car in high school back in 2004. I want to be a car designer professionally but don't have the money to go to the schools. To be an automotive designer it takes getting a BS. Yet I designed this car in high school and here it is today as the next big thing... Life is crazy.

[@wololo10]

They should've gone blown diffuser :(

[@alesksander]

Maybe yeah. But for example zirotech for heat protection is VERY VERY expensive (even if they use foils for protection is pain in ass for carbon fibre resin). From economic standpoint, maintenance and engine tuning maybe is better to get basics right first. Furthermore if we look pragmatically. If they put turbo engine in that car in future, all exhaust energy gets lowered so effect is even lower. And final nail in coffin for EBD. All that development of aero tools for PROPER gas exhaust testing and CFD , wind tunnels (lasers, smoke, optics) takes long time, is VERY HARD and EXPENSIVE. Even F1 teams failed flat in that area, not to mention boutique Aston Martin and its limited R&D money.

[@redhuntrr6143]

Should've called it an aston martin vortex

[@Phos9]

Based on the direction Aston has been going, that seems like a good thing. Sure, chop down the spoiler and then be forced to make the new awkward looking rear aerodynamically behave like the spoiler is still there. It’s like there’s something wrong with their brains.
