I’m having some trouble here too😭

[long crystal]

why the clown reaction

lol

[raven dock]

my teacher punished me by making me attempt to calculate the airflow off of a rear wing by eye

the red lines indicate that

the white and light blue are the shape, and everything else was just me noting roughly where different aspects of stuff should be

[bronze scaffold]

how can you calculate by eye?😭

[raven dock]

don't be late to lessons

[mild nacelle]

i cant add image here, but can someone please tell me what that wires (4 of em) thing is in mercedes w11 brake ducts

[bronze scaffold]

is it not the BBW technique?

[zinc bison]

Are you referring to these?

[mild nacelle]

yup

[zinc bison]

I believe theyre just more airflow deflectors/ components

[tall wyvern]

They’re debris guards

[mild nacelle]

But why just one section?

[tall wyvern]

That’s the caliper duct which is more at-risk than the disk + it’s regulated

[zinc bison]

What year is this, and how did Renault wind up in this position? Poor forecasting? Surely by the time its foggy enough to be unable to see apexes they bring the car in, let alone after a light layer of snow has fallen?

Why did mercedes initially go with the no sidepod design in 22? What were they trying to achieve?

[torn field]

The original concept of the car was a bit draggy so they tried to cut down the sidepod shape to minimize that iirc

[frozen peak]

Ok thanks

maybe it's an attempt to create vortices

pretty sure they’re similar to “bunny ears” - search them up, they help direct airflow down towards rear wing rather than above it

A lot of teams going for the overbite

[topaz lion]

the sidepods are way different. a smaller inlet, and a steeper undercut

now that i have seen the sponsor reveal video once again, they have already teased it

[fair heath]

taken from insta

2nd circle i made

because it looks like another outlet

[raven dock]

what else should I do for this front wing? I need to keep it minimal, and I'm aware the body is insanely raised, I'm working on the floor, and I just need clearance from the wing with it right now

[bronze scaffold]

interesting that they look like they’re loading the diffuser with that

[bronze scaffold]

Can we see the underside profile as well?

you could add a curved extrude to the side of the endplates asw to force airflow around/over the tyres

you could also curve the endplates so airflow goes laterally around the tyre

also vortex generators

as such

(regarding the endplate curvature)

[raven dock]

of the wing?

[bronze scaffold]

yeah

[raven dock]

it's basically just made of what you see on top

the blue plane is an upside down chord, and the yellow planes are just slabs in a funny shape

once I've finished the floor and made some sidepods and stuck the basic suspension arms and wheels on I'm going to revisit it

because then I'll have a better idea of what I'm constrained to, to keep the wing as similar size to the wheelbase as possible

[bronze scaffold]

hey, can anyone offer an explanation as to why the CoP being behind the CoG produces a restoring force to increase stability?

[tall wyvern]

Rotation is about CoG. Lift acts at CoP. If angle of attack increases, lift increases. If the CoP is behind CoG, the increased lift means there is a nose down moment, which lowers angle of attack and lift. If angle of attack decreases and lift decreases, the lift goes down which raises the nose and increases lift again. Aka stability.

[steady nest]

Are they adding some sort of cooling system in the cars this year?

[left geode]

Yes,there is the cooling system that will be installed in the car's halo if it's considered a hot race

sauber using LED lights to help with wheel changes

idk how it works tho

[prime mortar]

lights on the gun reflect off the wheel and show green when the nut is secured. Im guessing they use a sensor that turns the light green when the nut moves a certain amount under a certain force (to make sure it doesnt randomly turn green bc the gun rotated.

So something like:
Goal torque=x
Rotation=y
Torque=z
If y+z=x then green light.

[vapid quail]

that makes sense

This was already there in 2024 right?

[bronze scaffold]

I think a more efficient method would be a sensor that measures the resistance to the turning force - and if it hits a certain amount, you know the tyre has been secured properly. It would ensure that any faults with the wheel guns which cause slow rotation even with a normal level of torque would not deliver a green light.

Also a question - does anyone know where I can find dimensions to make a CAD model of the F1 tyre since 2022?

[prime mortar]

well my point is, if it strips a nut, that can cause a problem

Rb had them on the car 2023 but got banned later so

[charred shadow]

Well maybe some rules changed or the design we are seeing is a different approach

It's on the car anyway so it means the FIA saw it and was like "yeah it's fine"

For the people saying this is illegal, it's under the cake tin so perfectly legal. The regulations control the sealing of the cake tins so we don't get "blown wheel nuts" again, but under the cake tin is pretty wide open.

This looks like an elegant design to push air through

It's something that no one has done is these regulations

Everyone’s gonna have the flexi wings this year

Newey came up with those back in the day didn’t he? They made RBR remove it if I remember

Wasn’t it on Vettels car?

[iron shale]

SF-25

[left geode]

Yes, the flexible wings were a thing back in 2010, but again, you do need the wings to flex a little or else they would break or be too draggy from being too rigid at high speeds

[undone marten]

how exactly does a team "sandbag"?

do they remove some vital part or is it on the driver's part to slow down a little

[ancient juniper]

or just add weight to the car

[bronze scaffold]

seems that ferrari were NOT sandbagging

[amber kraken]

I'm rather curious about Danny Ric in the RB19. He supposedly clocked a P2 lap time during the 2023 Silverstone tyre test, despite spinning twice in it. Now we know that the RB19 fits Max's driving style but does it seem to also fit Daniel's natural driving style?

[lament rapids]

The car was build for max, thats why they have problems now. Adrian newey left the team and nobody really knows how the car works (my opinion) thats the problem with red bull

[true horizon]

Nah its incredibly difficult to build a car around a driver. That's what setups are for.

Some drivers are just able to take more performance out of the same car compared to their team mates.

Or a certain regulation period suits that kind of driver's driving style

[lament rapids]

Yes it is really difficult. But its really noticeable, that other drivers, except Verstappen, struggle with red bull, even if they drove other cars before. What is missing is newey who understood the car

There a lot of potential reasons why red bull is strugelling

[amber kraken]

What the hell happened to that right rear suspension?

https://www.youtube.com/watch?v=CaRG0Oguvhg&ab_channel=Formula1racesclips

[charred shadow]

It was probably already broken

Which is probably the reason why Gabriel crashed

[sour ether]

Some say the suspension was fairly stiff, so the strain put on it by the car sliding led to the snap. Not sure how plausible that is, especially considering it looks like there's some aquaplaning going on

[raven dock]

realistically, would it be possible for me to move the main intake to somewhere else on a car

like, it looks really weird, yes, and keeping the safety loop and halo is tough for safety

[urban quarry]

I mean where would you put it

[raven dock]

so, yk how red bull had the inverted L intakes?

stay with me here

what if somehow, that could connect to the engine

like, where the airbox would normally go to

[urban quarry]

You mean these guys?

[raven dock]

yeah

[urban quarry]

Now I might just be stupid, but is what you’re saying is, just remove the airbox and use the intakes on the sidepods to cool the engine?

[raven dock]

no

not straight just dump the airbox

take it off, yes, move it, and instead have special intakes on the sidepods in its place. in turn, on the top of the car, obviously there still needs to be the safety loop, and cameras, but there could also be a fin

sort of like how the MP4/4 never had an intake

[urban quarry]

Ohhhh alright

[raven dock]

I mean, I'm dumb as anything, never really done any in depth research of the cars

but the rules don't specifically state that an intake to feed the engine has to be on top of the car

or at least I never saw it, so it counts

[urban quarry]

Did some googling

You’d lose pressure from high speed airflow losing power

You would have better cooling and aero tho

[raven dock]

there needs to be some wedges

but I think I can work it out

[urban quarry]

Id gladly hear you out once you do

[raven dock]

I already started on it

[safe cloud]

Hi

[cyan badge]

https://fxtwitter.com/tgruener/status/1900091313887801504

[charred shadow]

It's weirdly beautiful

Am i wrong for thinking that?

[candid schooner]

It’s very interesting

And smart

If other teams figure this out quickly, could it be the end to their car advantage?

Sector 1 and 2, the car was very similar to the Mercedes and Max Verstappen, but Sector 3 the car flew in qualifying

Definitely interesting innovation, curious to see how other teams will take it

[charred shadow]

It's not only that, the front suspension is something that no one has ever done in these regulations

[marble stirrup]

[topaz lion]

this reminds me of mercedes tyre heating from the brake in 2018 for some reason

[mighty mist]

Surely other teams have their own versions of these parts? It’d be one aspect of their tire management. Ferrari had good Tyre deg last year so they should have something like this. It’s just not getting as much attention for those teams since it’s not on a strong car rn

[topaz lion]

yeah

[charred shadow]

I think it's all in the suspension

[cyan badge]

In addition, we can also consider two more aerodynamic appendages which bring the fluid mass downwards. Furthermore, it must be said that in this case the output flow has a great relevance for the management of the turbulence of the front wheel. These appendices from the downwash effect they take care of moving the vortex downwards which then detaches from the rubber itself.

The purpose of this solution is very attractive, as it is linked to other design choices made by the Woking team. If you remember, we explained that for the F1 car participating in the 2025 world championship, the front suspension of the MCL39 highlighted a high percentage of anti-dives, for aerodynamic purposes, emphasizing the risk of accentuating a thermal asynchrony on the axes of the car.

Doubts shared by Pierre Waché, technical director of the Red Bull. The Austrian team of F1 had real problems maturing some experience, in that the too marked anti-dive decreases the percentage of load transfer that activates the internal elements. Caution, we are not talking about the total share, but only of that portion which stresses the internal damping components. The load will then be unloaded on the arms.

If on the one hand aerodynamics are improved, however, on the other the energy that is developed in rubber decreases. This translates into the risk of a not indifferent thermal asynchrony, given that the front could heat up less. In the case of McLareninstead, with the solution designed ad hoc from the technical department, this type of problem is also avoided and the front axle can be brought to perfection.

[lament rapids]

Just look up in the reglement on the fia website

The exactly meaning is a secret of the team. But, as you can see on the picture, there are switches you can spin. ENG1 is the engine switch on position one. SOC1 is State of charge position one. (For example) The source of the picture is https://www.amalgamcollection.com/products/ferrari-sf-25-steering-wheel-2025

I am aware of this. Ive looked through some onboards and found out RBR's equivalent might be Burn 6 Mode 1, but im not entirely sure.

[lament rapids]

Only the teams know the exactly meaning, as i said

[keen sigil]

They activate Mode 1 before quali laps and change to Mode 13 afterwards, so its plausible to assume Mode 1 is full-push and Mode 13 is recharge mode

And Im going to retract the "Burn 6" statement

RBR

[lament rapids]

rb?

[keen sigil]

maybe, but now I would have to lie

[stray ibex]

does anyone know what article dictates the maximum fuel capacity of f1 cars?

[vernal wedge]

FIA Article 6.5 ?

[stray ibex]

The regs I found talks about the post-race sampling in 6.5

I think it's no longer mentioned anywhere

2021 had it in the sporting regs

now I think they put a max flow rate

serves the same purpose ig, dont feel like doing the math to make sure tho

[lament rapids]

Thats the problem with the flexible wings. If you make it too flexible it just snaps

[full steeple]

Also the air pressure. The wing is light, going 190mph to 80mph in 3seconds puts stress on the carbon which causes the flex and too much cause it to break itself.

[lament rapids]

Yes of course. The swirls of driving closely behind don't really help either

Hope they can fix it for japan and other tracks

I'm looking forward to Wednesday, what will be decided at red bull. Ralf Schumacher said that Tsunoda will be pulled up and Lawson should go to the junior team

[full steeple]

yes, Tsunoda is outperforming the A Team driver he shall take his place.

Liam needs practice and a faster car he cannot perform in a difficult car.

He is co uncomfortable in the Rb

[tall wyvern]

I think you might have this backwards. Unloading the wing lowers the stress.

[bronze scaffold]

The commentators did mention Tsunoda may have gone over a curb which unsettled the wing slots and perhaps slightly impacted its structural integrity, so the changing loads on the wing eventually ripped it apart

[full steeple]

You are correct I have the numbers backwards, thanks for pointing that out.

[dark snow]

Does anyone have the typical length ( or better yet the MCL38’s ) of a front wing end plate?

Printing a 1:1 car and I think I’ve got the scale too small

Research says closer to ~30 inches while mine is 13 inches

[neat kettle]

That’s not public info so you’d have to take your best guess at it

575mm is a good estimate

[dark snow]

I’ll scale to that then print this again then, thanks!

Way too small yeah

No worries! Very cool what you’re doing

That’s 22.6 inches so u don’t have to waste ur time searching it

[dark snow]

Yep Ty Ty

Just a cool summer project this year

Won’t be the entire car only part of the air box to the front wing

Like those simulators that cost your soul

[neat kettle]

You should use it as a sim in the end

Provided it’s durable enough

[dark snow]

Yo that’s gonna be cool asf

Moza wheels are nice I’ve heard

fitting everything is one of the last steps anyway

gonna be a tiny bit conservative

~460mm for the endplate tip to tip

[dark snow]

Corrected size

Split the piece on the right in half then scaled up

It might still be the tiniest small still but it’s way way more closer to scale

And goofed off with the one I printed

[amber kraken]

Another question. What on earth happened to Lando's brake pedal towards the final laps of the Chinese GP? The brake pressure was normal, according to his race engineer. But what made Lando's brake pedal to basically "go to the floor"?

[bronze scaffold]

Typically a loss of brake fluid or air bubbles in the brake line can lead to increased brake pedal travel, even if brake pressure is not reduced significantly

[bold viper]

Yo that is so cool what is it for?

[dark snow]

[short ether]

Really dumb question but can redbull have 2 differently designed cars 1 with max's overspecifcations and one for the second seat driver that isn't heavily modified and easier to drive?

[neat grove]

https://youtu.be/qyFZSGj20k4?si=a-kQkuC7gAsvWo1a

Red Bull knows this about Max's driving style. I wonder if they are analyzing their academy drivers styles to see if they can cope instead of just throwing them in willy nilly and hoping for the best.

This is very similar to Senna who wanted a really sharp front end, loose rear, and absolutely hated understeer. Sometimes it's just talent.

[tight cloud]

BAHAHAAHA

[dark snow]

New compared to old

Still smaller than real scale but I don’t wanna restart again

[dark snow]

new endplate is 495mm, still far off?

if its that drastically off then i guess ill start over again

but id really like to keep this one since its already taken up some days of printing and 1kg

[tall wyvern]

Just look how long the box is in the regulations

[dark snow]

Guess so yeah

Might stick with this one i think though

Final piece tomorrow

[lament rapids]

The base is the same car, just the setup for the drivers is different (depents how the drivers or engineers want it

[amber kraken]

Just goes to show how the F14T was an absolute wrestling match to drive

https://www.youtube.com/watch?v=Sei1tt2BKwI&ab_channel=yelistener

[left geode]

What's worse was that if Ferrari didn't went with the V6 with a smaller turbine, they could've been much closer than Mercedes than RedBull

From MotorsportMagazine article in 2014:
Furthermore, although the Ferrari F14T’s aerodynamic performance is believed to be quite respectable in isolation to the rest of the car, it appears still to be not the best in this area. In pre-season Bahrain testing Ferrari attempted to isolate its shortfall in pace by running the car disregarding the fuel flow limit in order to give approximate power parity with the Mercedes. In this form – which would be outside the regulations of a Grand Prix weekend – the car was only around 0.3s off the Mercedes rather than over one second when run to the regulation fuel flow limit. It indicated that although the power unit was responsible for more of the deficit than the aerodynamics, the aero was still lacking – a disappointing outcome when the concept of the car had been skewed in that direction, with compromises knowingly made on the power unit.

[ebon orchid]

pretty reasonable why alonso left ferrari after this car

[twin patio]

saw this

seems like they expanded a lot

[dark snow]

Endplate done, moving onto small aero surfaces rn then we start printing first large wing pieces tomorrow and through this week

Everything is printed with extra exterior walls so this can be heavily sanded to be smooth and flush before painting

Especially the “weld marks” with the 3D pen

[zinc bison]

How do we feel about the proposed V10 rules? Will the manufacturers like it? Who (Audi) will drop out?

[ebon orchid]

i dont think the engine manufacturers will like it very much

since they poured so much research and money into turbo hybrids

[quiet mantle]

I do believe some things should be left in the past, if sustainable fuels becomes more viable try V8’s first

[worldly ferry]

what do enginers mean when they say" we are target +3?

[naive needle]

For me it's probably just a political move to gain popularity now that the FIA elections are approaching.
Bringing back the V10s doesn't make any sense. F1 exists primarily as a testing ground for technology, and manufacturers are focused on developing hybrid technology.
Also, they've been working on the new hybrid engines since 2023-no one would want to throw all that work away.

[marble stirrup]

It means the car has 3 laps more fuel or energy than planned.

[uneven obsidian]

I love the hybrids

[topaz lion]

the target pit stop lap discussed in strategy plans prior to the race plus 3 laps

that's when they will pit

[fading cosmos]

Anyone know what this means?

[zinc bison]

I considered this too, however the actions of the FIA in the past since about 2000 indicate that that is not actually what the sport is about
Focusing on an issues like the hybrid technology when things that could be perhaps easier to implement such as the tuned mass damper that Renault made aren't implemented in road cars?
I feel that the idea that formula 1 is a test bed for road car technologies is also a cop out

[wintry mural]

f1 is insane

[violet smelt]

Basically, at the coordinates for Xc= -2030, the radius of the corner is 400, whilst at the coordinates for Xc= -875 the radius is 2500.

This means that the curvature of the part in question is a convex curve that increases between the Xc coordinates

[fading cosmos]

What confuses me is which part actually requires the specified radius. It’s hard for me to understand without a picture

[tulip meteor]

how do people access telemetry onboards???

[wintry mural]

[lost jungle]

So are the 2025 cars faster than the 2019 cars now? Or did the different track conditions give the 2025 cars an advantage? as the pole time was 0.081 secs faster

Which a pretty small margin

What are the criteria to be eligible to compete in an fp1 session? Could Shane Van Gisbergen, Denny Hamlin or Dale Jr. complete an fp1? Even someone like Kobayashi or Tom Kristensen?

[undone marten]

Do you reckon one day f1 will stay at the exact same speed because of the human limits of g forces?

we might be getting close to it

[raven dock]

from experience, split into the individual parts, most of a car could be carried through a house

even still, the individual elements could too

[amber kraken]

I'm still getting the feeling that the second Red Bull seat has the "Daniel Ricciardo Effect" in it

What I mean is that Danny Ric couldn't adapt his driving style around the McLarens, most especially with the 2022 McLaren, while Lando managed to adapt to its tricky quirks. Which is sort of similar to the Red Bulls' rather difficult adaptability for some drivers. Max is alright with it since he has the talents and driving style while Pierre, Alex, Sergio and now Liam had their own struggles with the RBR cars

[scarlet sapphire]

Engine meeting on Friday at Bahrain could lead to a different ratio of combustion/electrical power for the 2026 hybrid PUs. Right now they are targeted at a split of 55/45. Some manufacturers prefer 70/30 or 80/20 at least at the beginning.

making a 3d model rn and i wanna ask, what are the purpose of the black and slightly dented inward holes around the wheel cover?
i thought they were sensors the entire time but im not sure and im prolly wrong ash 💔

[naive needle]

maybe it's there to hold the wheel covers in place

[lament rapids]

Its to release the air of the tire, they are similar in karting. Or they are there to hold the rim and the cover together.

[lament rapids]

As he said

[dull agate]

ah, Ty both for the insight 🙏

[naive needle]

I did some research, and it turns out the smaller holes are indeed there to hold the wheel covers. The bigger hole is for the valve, as you can see in this video [https://youtu.be/RgdOJv-rcuU?si=MOQZirEATETVzB69] (4:15)

are there any official sources for f1 showcar models that have its parts separated (e.g: front wing, rear wing, rear wing flap etc) or would i have to make one from scratch?

[dull agate]

https://sketchfab.com/3d-models/williams-2024-30aadca90a4240b7800572cf75957853 found this on sketchfab

honestly, finding a fully textured accurate one is near impossible

but making one is also gon be hard, less impossible, but still going to take a shit ton of time

i have like 8 months of blender experience and im still not fully there yet (skill varies for everyone, it might take less time for you.)

but if you do pick up blender. best advice is keep at it even if youre ass

or just download that fw46 but youll have to texture it 😭

[reef plank]

yeah

just thought the fia would do something nice for once: obviously not

there are a few 2026 chassises on sketchfab but i dont have much blender experience to separate say the front wing and the sidepods

its just wheels, wheel covers, body and body 2

just want to analyse aero intake based on damage

[dull agate]

sorry but you gon have to do it yoself

its super easy

but

tedious as shit if you doing alot of it

It was infact a vortex

[sullen wedge]

what are mandatory race tyres ? Like are teams supposed to use atleast one tyre type for one stint before going softs 🤔 ?

[vivid walrus]

Teams are required to use two different compounds during a race, so out of the three available tire compounds they have to use at least two of them during the race

Doesnt matter how long as long as they do it

So they could technically do 1 lap on softs and the rest of the race on hards if it was possible

Así es como los equipos de F1 sellan el suelo con la normativa actual.
︀︀Cuando se diseña la aerodinámica de un F1, quieres impedir que la estela turbulenta de las ruedas delanteras entren bajo el suelo del coche. Al final, el suelo genera tanta succión que actúa como un aspirador MUY MUY potente. Estariamos inyectando aire con muy poca energía útil y solo "molestaría" al resto del flujo que viaja bajo el suelo, y al que SÍ se le puede extraer energía y transformarla en carga aerodinámica.
︀︀La solución que los equipos han encontrado es optimizar el encuentro entre el aire exterior a alta presión y el aire a baja presión del suelo, de manera que cada uno de los perfiles del "floor edge" actua como un "shedding edge" del que se desprenden varios vórtices que más tarde se fusionarán en un vórtice mayor.
︀︀Este vórtice actuará de barrera entre el aire exterior e interior del suelo.

If you look at the shape made by the recirculation bubbles in the wake of an Ahmed body, it's surprisingly similar to the shape of the McLaren diffuser near the crash structure. Placing bodywork in place of the wake stops the wake from forming, but gives you all the aero benefits

[past burrow]

I dont know he is using but as an automobil engineer student i can recommend some

[sweet tree]

Does more downforce always mean more drag?

[vast portal]

Depends on how you create the downforce. If it is created by wings, then it does create more drag. But creating downforce by floor and ground effect in general is less draggy

[sweet tree]

That's what I thought but I'm not expert

[sweet tree]

and do you get less dirty air from less drag?

[vast portal]

Dirty air isn't caused by drag. It is caused by air flow separation

[tall wyvern]

And also the upwash from the car/wings aka induced drag (and also generally from viscous losses from friction/reynolds stresses, which is friction but in the air itself rather than on a surface)

[latent lake]

F1 cars have wheels

[urban orbit]

Your a genius

[gritty spade]

Ferrari engineers,take notes

[marble sleet]

https://www.youtube.com/shorts/X76wiqjWURM

[sweet tree]

I'm really just trying to understand how dirty air is worse now because of the floors like people have been suggesting.

since I thought it was supposed to be better

[vast portal]

It was supposed to be better with these regulations, but as the development of the cars goes on, the teams find more areas where they can implement a new aerodynamic feature that doesn't always reduce dirty air

[sweet tree]

So it's not necessarily the floor's fault?

It's just teams developing the car

[vast portal]

The development plays the main role. Because the floor was particularly modified by the regulations to reduce dirty air. Great example are the aerodynamical regulations going from 2008 - 2009, the cars looked completely different.

[raven dock]

3ds max... and Microsoft paint

[raven dock]

it was a bit thin, yea

[dull agate]

not a bad first attempt tbh

my first attempt looked exactly like that lol, you gon have to keep at it while deep analyzing f1 cars and you def will be good

keep that shit up gang

some advice id give tho, air intake and that upper part of the engine cover needs to be higher (not totally above the halo but still a bit higher)

rear wing needa be a bit taller/bigger

Does anyone know why pneumatic valve springs don't get used in consumer vehicles? Even for performance based cars or sports cars? Is it cost or complexity or something else?

Surely the use of such tech unlocks an incredibly high rev range no?

[topaz lion]

so it's just derating

[left geode]

Yeah,but it's more like the ERS is disabled under certain speed or battery percentage to conserve it

[topaz lion]

yeah

[tulip vault]

the mclaren wheel cooling theories are really interesting

[lusty pendant]

looks like some changes for red bull

[stuck yarrow]

cost and complexity because pneumatic systems require specialised components like compressors and seals. just having more components in the engine already increases points of failures decreasing reliability for practically nil benefits since road cars dont rev all that high to begin with.

pneumatic valve springs were developed when cars began to rev above 15k rpms because at those speeds metal springs couldnt keep the valves closed without suffering from major valve float or outright failure.

road cars rarely rev beyond 9k rpm with very few exceptions pushing higher.

[stuck yarrow]

the ecu is brilliant, i wish id get to work with those things.

[jagged monolith]

mode 6 and start 5 is most common be the most power sended to the engine no?

[stuck yarrow]

huh

modes are defined by the teams and not standardised terminology

[jagged monolith]

i watch currently red bulls onboards so

i should watch others team onboards

[stuck yarrow]

each team has actually got their own ecu software which handles these things

to complement their engines

because each engine has its own maps and power delivery modes

[stuck yarrow]

i could never

too much work

good luck lol

thats dedication

[jagged monolith]

wait so if mercedes engine 100% is start 2 williams use the same?

[stuck yarrow]

nope

the modes have to suit the car as well, there still are differences in chassis and aero to be considered

and the teams develop the engines themselves after they get the engine from the team they bought it

so the powertrains start to diverge after a while

[jagged monolith]

well we all agree strat 12 is for pitlane lol

i see that aston martin with the upgrades they improve like 0

its kinda senseless to have a killer engine if your chassis constrains the cooling flow or you have packaging issues

maybe their chassis cant handle the power unit appropriately

also maybe their upgrades or integration are lacking despite the mercedes power unit

I have the same question. Why where the medium tyres so fast?

[stuck yarrow]

the soft compound was exhibiting overheating issues

the medium was able to maintain a temperature within its optimal performance window for longer

and therefore was faster for some

https://press.pirelli.com/pirelli-on-the-soft-side-for-miami-and-imola/?utm_source=chatgpt.com

it was the softest of all compounds for the season, c6

[near inlet]

Ah I see, thanks!

[stuck yarrow]

The turbocharger works best with the current powertrains because the narrow, compact V6 allows all six headers to route efficiently into the turbocharger with symmetrical flow, which helps spool the turbocharger faster and more evenly, whereas the V8 requires either twin-turbos or an overly awkward routing setup which only complicates the design. Additionally, the MGU-H integrates directly into the turbocharger to recover energy from exhaust gases, and the V6 layout makes it much easier to place the MGU-H directly in line with the turbo shaft between the turbine and the compressor, whereas the extra width of the V8 would once again require a more complex setup.

Another factor to consider is that the V6's 120 degrees crank angle means each cylinder fires evenly every third of crankshaft rotation, which makes the exhaust flow smoother and more predictable, perfect for the turbo to operate with little lag. @uncut peak

Now, the reason why the current hybrid powertrains don't sound as good as you might expect from a high-performance engine is that the turbocharger muffles the sound, the low RPMs compared to the previous engine configurations produce less sharp tones, and the ERS deployment effectively negates the roughness of power delivery, which further reduces the aggressiveness of engine tone. The engine would sound perfectly fine were they to: redesign the MGU-H to let the turbo spool more freely--in fact, the next set of regulations may bring better-sounding engines with its removal; increase the RPM band of the engine; tune the exhaust to produce better sounds.

Teams don't care though. Better sounds don't make the cars faster, and it may even harm performance.

Hello I have a question:
When a driver reports potential damage or wear down of any part of a car, how does a team detect it? Like I get the car is ridden with sensors but do they cover every cubic millimetre of the car?

[abstract pawn]

Sensors, driver feel or sometimes just visually by looking at the car through either the live broadcast or photos or just your own eyes from the pitwall

[stuck yarrow]

Sensors are strategically placed, which means that any failure of relevant parts will be detected by one or more of them sooner or later, even if only indirectly. Nowadays, teams collect massive amounts of data in realtime and it is up to the engineers to make sense out of them.

There are sensors for suspension load, brake temperature and wear, tyre pressures and temperatures, power unit statistics, gearbox and hydraulics, steering angle, and torque. Many others, but I can't name them.

When a driver says 'check the rear wing', for example, the engineers will try to compare the telemetry to previous laps or otherwise expected values, look for asymmetries in load and temperature, and check onboard footage and GPS data.

It's all picked up one way or another. Every issue with the car results in some measurable drop in performance or other sorts of anomaly in telemetry.

[tall wyvern]

The real answer is pressure taps everywhere

[raven dock]

screw it, I want to know what an inline engine would be like

[stuck yarrow]

Inline engines were actually considered the norm in the 50s and 60s, as the V shaped layouts weren't sufficiently fleshed out to be employed at the time. Early on, F1 teams prioritised simple and proven designs because they were easier to design, to cool and to maintain and repair, whereas the V engines were mechanically more complex due to crankshaft, dual cylinder banks, lubrication and cooling designs. At first, the engines were placed in the front of the car, so they worked best with narrow inline engines and so did the centre of gravity of the chassis, as opposed to the wider engine bay of the V shapes.

Generally, they tend to offer better reliability due to less moving parts, but they've been incompatible with the designs of the cars since the early 80s (with BMW's turbocharged inline 4, worth reading about) and especially after 88, when turbochargers were banned and V-shaped layouts made a comeback (this time to stay). In modern cars, and especially with the hybrid powertrain, they wouldn't work and even if they did, they wouldn't deliver as much power.

[raven dock]

fineeee

Mclaren is 2 points behind what Red Bull was at round 8 in 2023
But gap 1st WCC to 2nd WCC in 2023 round 8 was 154 points
In 2025 WCC round 8 its 172 points
So that means McLaren is more dominant than RedBull 2023 for now as of round 8

[rapid oriole]

Also if they were using the same points system McLaren would be technically ahead

I say technically because if a fastest lap point was available it may have changed who actually got the fastest laps due to people stopping to go for it

Ferrari's front and rear wing for Barcelona

[cosmic elm]

Flexi-wing
it flexes at high speed for more speed
but doesn't in corners
does the difference in newtons between straight speed and corners differ so much that it can differentiate between the two?

What is the use of a front wing? Only for more downforce as well? Or does it have different uses?

[restive bridge]

looks like it’s just got less downforce

which makes sense because spain

[tall wyvern]

Massively yes, but it’s not an on/off thing like you’re implying. It’s gradual over the downforce changes. The main reason is for balance, not for drag. The drag vs load slope for front wings is very flat.

[tall wyvern]

The main uses are downforce and well conditioned flow to the floor/rear of the car

[left geode]

And pretty much without the front wings conditioning the air to the rest of the car, the car would become a literal block on wheels with the amount of drag

well thats definitely not true

[snow phoenix]

you wanna debunk this?

the wheels are a draggy component so they create turbulence

[stuck yarrow]

yes try racing without tyres

[snow phoenix]

the air coming from the front wheel hits the rear wheel which means theres a turbulence right?

[stuck yarrow]

the car is a source of turbulence itself, doesnt mean you can remove the car

[snow phoenix]

there saying that the wheels dont cause turbulence/dirty air

and im like thats simply not true

it obviously does lmfao

[snow phoenix]

wait was my statement correct?

lol

some of these people in f1 technical just not giving the correct information on some things

i feel there should be some validity to some of these things

instead of just spouting nonsense lol

[stuck yarrow]

yes tyres are fundamentally detrimental to airflow smoothness because they accelerate passing air unevenly with their rotation and the also uneven shape of the tyres as they wear and get distorted by outside forces further this effect

[snow phoenix]

yup

[snow phoenix]

so theoretically if u put covers around the wheel there would be less dirty air right?

and also the water spray off of cars would be less right?

[stuck yarrow]

you don't want covers around the tyres because they ruin the cooling

Does more downforce always mean more drag?
Angel_ — 05/06/2025 11:34 AM
Depends on how you create the downforce. If it is created by wings, then it does create more drag. But creating downforce by floor and ground effect in general is less draggy
Vertex — 05/06/2025 11:51 AM
That's what I thought but I'm not expert
Vertex — 05/06/2025 11:52 AM
and do you get less dirty air from less drag?
Angel_ — 05/06/2025 11:54 AM
Dirty air isn't caused by drag. It is caused by air flow separation

[snow phoenix]

techinically

[sweet tree]

My question was answered a month ago

[snow phoenix]

well only to found a month later

that information that was given was factually incorrect

[sweet tree]

how so

[snow phoenix]

scroll up

[sweet tree]

I don't think anyone said this

[stuck yarrow]

are you applying the logic to the last bit angel said

[snow phoenix]

yes

lmfao

that last bit was wrong

and medici debunked it very well

[stuck yarrow]

that last bit is somewhat of an oversimplification because there is indeed a slight correlation between both effects though not directly, as they essentially stem from the same phenomenons. that is flow separation, vortex generation, and turbulent wake. in the case of pressure drag that is, which is a big part of total drag. flow separation is when the air detaches from the surface of the car and creates a low pressure wake behind it, and this also generates dirty air. vortexes are mostly generated by the wing tips and endplates, and also increase drag and disturb the airflow.

[sweet tree]

I'm trying to find where someone said that wheels aren't draggy

[stuck yarrow]

but that doesn't necessarily mean they're one and the same or proportional in nature though they generally go hand in hand in design

all dirty air involves some drag though.

[snow phoenix]

exactly

lmfao

[sweet tree]

okay 👍

[stuck yarrow]

ironically draggy features like rear diffusers and spoilers clean up the dirty air sometimes

[snow phoenix]

which means that the wheels are a dirty air component

ding ding

[sweet tree]

but nobody mentioned wheels?

[snow phoenix]

tyres i mean

[sweet tree]

nobody mentioned tires either

[stuck yarrow]

yeah

[snow phoenix]

or the 4 bits of rubber when they are spinning

ye

[snow phoenix]

no but we were saying that the statement of "drag isn't caused by dirty air" was incorrect

[sweet tree]

dirty air isn't caused by drag*

I'd like to hear Angel's rebuttal too

[vast portal]

I didn't say that. I said dirty air isn't caused by drag

[tall wyvern]

Not necessarily because the upwash behind the car is reduced angle of the attack for the car behind, which is dirty air but not drag. I would argue that dirty air is mostly a product of lift actually, and that drag is also a product of that lift and thus they are related - other than tyres which is just pure separation.

[stuck yarrow]

Increased lift implies in increased drag through induced drag, because of the vortex structures formed by pressure equalisation, therefore lift is indeed a great source of drag but not the only source in a car. Dirty air exists independent of lift as well, though you're right to point out that lift is a major cause.

But as I said dirty air and drag are not mutually dependent, they just happen to coincide because they share roots, one of which happens to be lift.

I do acknowledge my statement was too broad though.

[tall wyvern]

Drag is caused by upwash, not the other way around. The lift increases the up wash which increases the drag and also decreases the onset angle of the following car. Dirty air is mostly caused directly by lift either way.

[stuck yarrow]

That's partially wrong, and even then I don't see how any of that conflicts with my explanation.

Induced drag is caused by the generation of lift, resulting in vortices and downwash behind the wing, and by Newton's third law, upwash ahead also. These reorient the net airflow, tilting the aerodynamic force backward, and this is induced drag.

[stuck yarrow]

Upwash doesn't cause drag by the way.

As I said, lift causes upwash and downwash due to varying pressure across a wing or body surface, and my explanation above elaborates into how this translates into induced drag.

Tyres and suspension arms also contribute to turbulence, mostly tyres because their behaviour is extremely hard to predict and it takes intricate aerodynamic adjustments to adequately reroute the airflow and minimise their effect.

And you're essentially describing what dirty air does, not where it comes from--and that is the matter here.

[tall wyvern]

Not on a race car since the wing is the other way up.. what do you think the tilt of the vector is? It’s literally caused by the upwash. Aka the up wash causes an induced angle of attack which changes the lift vector. Aka the upwash.. causes drag..

[tall wyvern]

It’s change of incidence of the following car caused by upwash + loss in total pressure caused by losses due to shear stress and turbulent dissipation. In other words energy taken out of the flow due to viscosity.

[stuck yarrow]

I don't see how that conflicts with my view in any way. You just elaborated on my point on what dirty air is. It is indeed geometric distortion and energy degradation of the flow.

[stuck yarrow]

Indirectly.

It also depends on your perspective, because when I said downwash is the source of drag, it is from the perspective of the surface (that is, the generator), not the follower.

Your argument is fundamentally different from mine once you analyse from which perspective it is elaborated.

From the follower's perspective, upwash alters the angle of attack, reducing downforce and increasing drag due to a misaligned lift vector. To the follower, upwash causes loss of downforce and an altered drag profile. Dirty air as you said is an energy-degraded flow, in that there is loss of total pressure due to viscosity and turbulence, plus a geometric disturbance, which is the upwash reorienting the flowfield.

From the surface's perspective and my point on the discussion you started subsequent to mine, downwash causes induced drag as it tilts the aerodynamic force rearward.

While upwash may indeed affect the aerodynamic forces on the following car, that doesn't mean it's the source of drag generation itself, but the byproduct of upstream lift-induced flowfield deformation, specifically the pressure differential that creates lift and also produces both downwash behind and upwash ahead due to circulation and momentum conservation.

I essentially describe why the flow has its properties, whereas you've concerned yourself with how that affects the car behind, which is beyond my point. Drag is context sensitive, you always have to ask which drag, and on whom.

Technically, we're both correct but essentially about fundamentally different parts of a very same physical interaction, as we have chosen different observer viewpoints of the generator-follower pair. If we fail to separate the two, we risk conflating induced drag with performance loss from dirty air, which are indeed linked though not the same at all.

[sweet tree]

damn looks like yall had some fun

[tall wyvern]

Not indirectly, the tilting of the lift vector is caused specifically by the upwash. That’s why the 3D curve lift vs angle of attack has a shallower slope than the 2D curve. The increasing lift increases the upwash which decreases the effective angle of attack. It’s also why the induced drag increases with the square of the lift coefficient. The higher the lift, the higher the up wash and the more tilted the drag vector becomes.

Why would upwash increase the drag on the following car? It decreases both the lift and the drag on the car because the whole car is at a lower incidence.

[stuck yarrow]

Have you read the rest?

[stuck yarrow]

To the follower, upwash causes drag.
I got that messed up, dw. I was supposed to go a bit in depth about the aspects but I didn't get to finish this sentence.

Sometimes my messages get messy because I keep going back to earlier points to articulate better.

What I'm saying is that I don't care about the follower, which is whom you're basing your arguments off.

I'm talking about the generator. Drag doesn't produce dirty air. But the roots are effectively the same, in the case of induced drag.

Features that generally induce drag also tend induce dirty air.

There is a slight correlation between both, although not a proportion or a direct relation, as I said earlier.

They do exist independent from each other.

When I say every dirty air implies some form of drag, it means there has to be a disturbance in the first place.

Is there a rule regarding the number of pedals in an F1 car in the current regulations? Can, hypothetically, a team add another pedal for active-aero element in 2026?

Having just watched Canada 2007, specifically Kubica's accident, I have to ask; How necessary is the current size of the cars in relation to safety? and what features have been added since 2007? Kubica walked away from his accident with a sprained ankle, no? A 2007 car with a halo, size wise, would surely make the racing a little more exciting

[quiet mantle]

The cars are being shrunk a little next year

[zinc bison]

Yes but 4.58m in 07 to 5.63 metres long, and from 1.8 to 2 to 1.9 metres wide. Yes, I know about the fuel tank taking up space, but the cars are so fuel efficient now its negligible.

[violet smelt]

Not very. IIRC the only size change for safety cells occurred in 1997/98 other than the Halo in 2018.

Cars are this big because bigger car = more aerodynamic surfaces

Feel free to post it and we can try for sure

[junior dune]

What's that?

[vivid walrus]

Where exactly on track did you find it

[proud flame]

The straight after turn 9

[vivid walrus]

My best guess then is that it came off Hamiltons car after he hit the groundhog

Probably a floor piece

[junior dune]

There is no blood on it so how it would be a groundhog?

[vivid walrus]

Could be a secondary part that got hit after, doesn't have to necessarily be the actual part that hit the groundhog

[junior dune]

Probably

[proud flame]

I was wondering that too. A piece that was compromised in the groundhog impact and then tore from the car when accelerating under high G’s.

[vivid walrus]

Most likely

[proud flame]

What part of the track was the groundhog hit

[vivid walrus]

Pretty much exactly where you found that piece

Between 9 and 10 on the straight

My theory would be he hit the groundhog, a broken piece went under the car, and either broke into more pieces, or hit something else under the car and broke off that piece

[proud flame]

Oh wow ok that makes complete sense then.

They had staffed off that section of the track with security and no one was allowed over there during the track access. I found it at their feet without needing to go closer over to turn 9.

Makes sense why they closed access off but it didn’t at the time- had no idea Lewis hit a groundhog during the race

I just examined it very closely and found lots of tiny specs of pink inside the white coloured material. Can’t pick it up on camera but it sure could be blood. Definitely supports the theory’

[vivid walrus]

Yea, could also just be a coincidence. They don't allow access to the entire track during track walks anyway. At Monza it was only the main straight to the first chicane. But you said it was towards the end of the straight? That would make sense

[neat flower]

i have a question for a fluid dynamics expert

[tall wyvern]

What is it?

[neat flower]

how does rain or even higher humidity change aero?

humidity i assume lowers ambient air pressure because there are simply fewer air molecules and more water vapour

but the flow under a car in the rain. what happens?

[worldly ferry]

what does the rules say about when its mandatory a race to finish under the SC?

[late urchin]

what's the point of a VSC? I don't really understand what it does, compared to a yellow for a sector or a safety car. I think it's supposed to slow people down? But a yellow and a SC do the same thing.

[delicate jewel]

VSC is for less severe incidents than an SC. It just slows everyone down in their current position, SC bunches everyone up. Yellow just slows down a sector

[late urchin]

so what kind of incidents would be the difference between a yellow, a VSC, a SC, and a red flag?

[delicate jewel]

Yellow is more so someone just went off track, VSC may be a minor accident with debris on track or the car is near an exit, SC is most common and for debris and accidents, red flag is typically for when an incident cannot really be cleared with cars out on track (most commonly with street circuits)

[worldly ferry]

what is the diffrence between brake balance and brake migration?

[abstract pawn]

Brake balance is just how much braking is done at the front and rear

And brake migration is when the driver starts releasing the brake pedal, then the braking power will start moving toward the front for example

Meaning that the rear brakes release faster then the front brakes

[eager sphinx]

Theoretical thought experiment: The rule is that "all cars must have no more then 4 wheels, out of which only two may be driven wheels." This is obviously saying AWD is not allowed only 2WD. Though it leaves room for FWD which has been discussed before, it's just not good enough usually. But hear me out what about a "left wheel drive" or "right wheel drive" 2WD with a longitudinal drivetrain. What would that in theory even look like? Would it work in Indycar where it's an oval that only turns left, or a small circle track? I can find nothing concrete of anyone ever putting this on any vehicle. How much of a nightmare would it be and would it have any advantage in any situation?

[vivid walrus]

The main issue would be the axles

Axles go straight across the car to opposite wheels

They would have to rework the axles to be lengthwise rather than width

Which would probably be more work than needed

[eager sphinx]

Why do a lot of people misunderstand x mode and z mode. They're not for strategy or will be used by drivers in strategic ways, they are only available in their respective parts of the track and they will basically be always on for that part. "X mode will be used by default for every straight" (technical director's words). It's just a new button for the driver to press in a new "DRS zone" just not called DRS. There is zero strategy element, this feature is just to make the cars better and optimised for a whole lap and be able to recover energy efficiently

It's the MOM that is strategic, which is taking the place of the "you get a boost if you are within 1 second of the driver in front" role that DRS had, but better now because it's not limited to a specific zone. X mode and Z mode on the other hand aren't going to be relevant to battles in terms of when someone presses it because it's meant to be the default for both types of sections of the track. Overtaking advantage feature is now to do with energy. I've seen a lot of people mistakingly talk about x and z that way like someone decides when and where to use it to have an advantage

[inner cliff]

because not many people are as knowledgeable about f1 as u

[upper ivy]

I feel like the terms themselves dont help

"DRS" is an abbreviation and fully spelt out it gives an idea if how it works

"Mode X" meanwhile might as well mean anything

[fading cosmos]

i created these polygons but they intersect themselves, does anyone know what's wrong with my sketch?

[tall wyvern]

Your second point is wrong. Surely you checked.

[tall wyvern]

It’s X and Z because Cx is drag coefficient and Cz is downforce coefficient, it’s not random.

[upper ivy]

TIL

[fading cosmos]

this is my 2nd point coordinate

[tranquil imp]

This is giving me ptsd

[violet smelt]

Is this for the sharkfin? If so it looks correct that it intersects

[fading cosmos]

yeah it's the sharkfin, i try to adjust the sketch

[fading cosmos]

if i following the coordinates it look like this

[tall wyvern]

Maybe your xc is too far backwards?

[fading cosmos]

My XC is currently 1930 mm from XA. I changed it to 1830 mm, and I also moved XA to 10 mm from XF. Is this still correct according to the regulation?

[tall wyvern]

Yes but it is sensible to define xa as 0, and move everything else around that. Xc xa will never change, but you might want to move your front wheels without moving the chassis.

[fading cosmos]

but is this still acceptable?

[tall wyvern]

If xf is behind xa then yes

[fading cosmos]

Looks like I got it wrong, thank you very much

[raven dock]

how realistically possible is this AI generated model? I kinda wanna make a version of it

[vague storm]

i feel like its possible to be a real thing

[vast portal]

[amber kraken]

Wasn't this before the engine combusted itself?

https://www.youtube.com/watch?v=d8H0XupTo1o

[wraith acorn]

that was gasly

[old parcel]

It was incredible how with the last regulation (2014-2016) the f1 car used to reach massive top speed

[blazing saffron]

yeah it was Gasly whose engine blew after hitting top speed

[onyx niche]

2017 was a better year

in terms of engine performance

cuz party mode was not banned yet

[amber pond]

What do you make brother i don't understand??

A F1 car model??

[inner cliff]

no sir he is making a tuk tuk

[raven dock]

rigging my 26' car for assetto corsa, will say how it drives

[raven dock]

so... I might've messed it up somewhere, because I just got a new PB, and the thing is, I wasn't pushing

[mossy axle]

I saw something with the new regs about the wings being able to open, is that only if you are within a second of the car ahead?

[tranquil imp]

🤨

[zinc bison]

Is there no ground effect for 2026?

[thin mauve]

Quick question: with manual override mode in 2026, will there be any regulations as to when it can be used, like how DRS had zones and requirements like being a second behind

[vivid walrus]

Yes, there will be zones for (X and Z)? mode, not sure what other requirements there will be though

[torn field]

correct

[amber pond]

Wtf

[tall wyvern]

There will always be ground effect because.. the cars will always be near the ground

[azure wind]

just that ground effect wont be the focus

the surfaces above will be more important

[zinc bison]

Allow me to rephrase: Will the 2026 cars have Venturi tunnels?

[quiet mantle]

I’m pretty sure someone said in another chat no

[static breach]

Nope venturi tunnels are banned

And the floors will be far smoother too

So they won't be the primary focus for downforce but rather the wings will be

[agile karma]

Im sorry if this is wrong but won't that make the cars more affected by dirty air again? Seems like 1 step forward for two steps back no?

[static breach]

I don't think it would at least not as poorly affected as the current cars because at least the air coming from the floor would be less disrupted though I'm not the smartest so don't take my word for it

I'm not even in college yet so I'm going off what little I've picked up

[agile karma]

Sound like we are in the same boat then 😅.

All good i just was curious becuase I thought that's what caused dirty air in like 2014-2021

[static breach]

Back then it was mostly bargeboards and other similar things that caused dirty air to be that poor I'm pretty sure bargeboards were outlawed in 2021 though which you can see a small change in how easily the cars followed compared to previous years

[agile karma]

Oh good to know, I only started watching f1 in 2023, so I've only watched the highlight races from previous years. Do you know what made bargeboards worse?

[static breach]

Yeah I only properly started watching in 2023 too but I've been paying attention to it for a while I couldn't give you a proper explanation as to bargeboards though but I could try

[zinc bison]

They conditioned the flow down the entire rest of the car, leading to enormous amounts of turbulence for following cars

[agile karma]

Nah all good if you don't know you don't know. I'll google it thank you.

[zinc bison]

It was about creating clean air around the sidepod and floor edge, leading to vortices that negativley affected following cars
