We got a free wind tunnel look at the cars. This is awesome. Great video ❤

Did anyone see the vapor cones that the Ferrari was creating underneath the car infront of the floor, behind the wheels? I think it was during the Sprint Shootout. It would happen during the long Kemmel Straight. At one time, the vapor cone was sorta flashing in snyc with the porpoising. It would appear like a cloud, then dissappear when the floor bottomed out, then reappear as the suspension/floor cycled back up. It reminded me of fighter jets doing high g manuvers and you'd see a large vapor cone on the wings. No other car was doing that. I wonder why only the Ferrari's were experiencing that kind of phenomenon? Edit: It was in Qualifying. Q2 around 6:20 left in the round as Sainz passed Max into turn 7 and really noticeable in Q3 with 12 secs left as Sainz approaches turn 7

Fantastic insight to the mysteries of aero and down force. Brilliant analysis. Thank you.

Thank you, thank you and thank you again. I was watching the Spa race with Ms Octane who is as avid F1 fan as I am. I, being a mechanical engineer with an interest in fluid dynamics, was getting all excited with flow visibility in the rain and spray. I tried to explain this to MsO only to be met with cool indifference. Glad to see and know that I am not alone

awesome video! I thought the grand prix was ok, not super exciting but not completely boring.

FIA: no out wash RB: Nu Uh 🤓☝

I enjoyed the wings in the front clouding up as a generated downforce towards the end of The Straits. And obviously I enjoyed watching the cars and seeing how their Arrow packages are designed as the water flowed over them around them

Max could follow lewis so closely in sector 2 it was crazy

You never disappoint. Thank you sir - awesome analysis!

I also saw an interesting shot of the Alpine from behind into the sunlight where you could see what looked like outwash vortices on both sides of the car.

Nice. The floor of the RB now make sense as that is pushing out the air with the floor.

Many thanks, highly informative!

I was thinking about this all weekend, that Mercedes Aero department was fixed on the RedBull. I noticed that the flow around Max's car was different. I'm waiting for more analysis.

Cheers for this insight/analysis :)

That was fast. Thanks for covering this.

Thank you very much... from Brazil...

Yessss!!! finally clear shots of the real deal :O

Been waiting for this video since I originally saw the track conditions at Spa. Hopefully we can get some slow-mo shots!

Wow thank you for making all that so much more clearer!!!! They talk about that on all the professional podcast all the time but they never dive into why or why the tire wear is so poor on the Haas. THANKS

Excellent video and explanations!

Great video b-sport.

FIA: The racing will be better Newey: Not on my watch

I love this guy.

Amazing content. Thanks! #shorts

Could you mock up some additional aero concepts that could help the FIA reach their stated goals better? I think that would be a super cool video to see.

Great video

It's important to keep in mind that spray may not __entirely__ reflect the airflow around the car. In order to fully visualise the airflow you want small, very light particles like smoke that don't have appreciable momentum on their own, as this means they will not "overshoot" the flow-line of the air molecules because they are too heavy. However, water droplets tend to be quite large; the tyres aren't designed to fully atomise the water droplets. So the spray may not be an entirely accurate representation of how the air is actually flowing around the car, especially the stuff that's being squirted out of the tyre contact patch.

So why are cars unsettling so much after being overtaken? A recent example is Lewis and Checo, as soon as Checo went in front of Lewis, Lewis' front snapped. I've seen this so many times in the last 2 years. Also tire deg seems (key word is "seems" Im not sure if thats the actual case) bigger now than before especially when they in dirty air, which leads to cars just slotting behind another car in the 1.5-2.5 seconds range. It seems to me the new regs did nothing to improve racing.

Great video. Far too often F1 'technical analysis' fails to address the key question: is this characteristic better for performance? And if so, WHY?

Great Video! Really this is just a simple solution on reducing drag, I think Mclaren big jump really shows good this philosophy is. And I think the Aston Martin needs a whole new sidepod design ( Probably similar to Redbull's to reduce drag ). The Waterslides seems like Something Redbull wouldn't benefit as much as the car is so good already. Mercedes were adamant that this concept resulted in a loss downforce, I think they didn't realize it meant drag was reduced instead of overall downforce. Explains why they stick with the zero-pod concept over the winter, but really this video shows it really wasn't the case. Hope they take cues. I don't think it ruined cars to follow closer, Redbull took a simple solution and improved on it though updates.

@1:33 it's impossible not to create wake with open wheels car whether it's FIA intention or not.

Can you look at the wake of the Ferrari behind the front wing and in front of the floor , looked different to the rest of the grid

Apparently the red bulls were lifting in sector 1 loosing 0.5 seconds , it was theorised that red bull were lifting in eau rouge to save their plank

Went to a few spray parties in college😅

how did the redbull look compared to the mclaren? Considering the mclaren philosophy, they seem to be closest to redbull design wise. i wonder if that means the outwash is similar from this spray as well

This is very juicy. Can you go more in-depth? Like more comparisons and conclusions?

Amazing video mate! Newey and his team haven't only managed to create one of the best F1 cars of all time, they've also managed to make it difficult to follow, both because of its performance and his aero😂😂😂

Amazing analysis , wondering why f1 comentators haven't done this yet.

Interesting to see Red Bull running the wet set up car in the dry and then needing to lift in order to avoid excessive wear on barge board when under compression.

Really interesting, thank you. Should the FIA step in to stop Red Bull throwing the front wheel vortices outwards in order to improve the racing (cars being able to follow), as this season there has been some regression in this regard?

B sport can you look at the Mercedes bouncing and the red bull, if you go on board with max p1 lap the red bull bounces on the straights and in the corners but less so when the drs is open. Lewis DHL fast lap award the Mercedes didn't have drs was bouncing more but when it had drs was bouncing less than without drs but still more than the red bull. Spa must be bumpy in Places but also both cars had porpoising in several locations.

Surely at the example of the ferrari, you can see the redbulls has the same spray as the ferrari's

Awesome video! I thought the race was good relative to the rest of the year. Nothing special, but when Max runs away with every lead it takes away a lot of excitement for the winner

I'm not an engineer, but would that explain why teams struggle to follow closer behind the Red Bull when they have such a shot?

So not only they get better top speed, better down force ,better tyre degradation they are also making it harder to follow their car

All very good,.. But,.. How are they (redbull) doing it?!

If the FIA wouldn’t have raised the ride height because Mercedes complaining, wouldn’t the cars have less side wake? Thus be better at following eachother. Seems to me the closer the groundeffect floors are to the ground the less bleed over you get and the less disturbance of wake to cars behind? Have the FIA shot themselves in the foot?

Very interesting and well spotted. Seems like a workaround for Red Bull, with their reduced wind tunnel testing time 😄

The red bull might be putting more wake outwards but it isn't anywhere near as bad as the 2021 cars.

So why is the red bull rb19 car not getting any penalty from FIA due to the not following 2023 aero dynamic regulations?

Mmm... I liked your analysis and I don't want to say it's wrong, but... Isn't the direction of the water spray more dependant on the wheel angle? I don't mean the camber, I mean the angle that Mercedes was able to modify with the DAS. As far as I know, front wheels are not literally parallel, they are facing inwards a little bit. If the Red Bull have this angle bigger than other teams, it could explain the direction water spray takes. Anyways, great video! Now I want to watch the highlights at 0.25x in a big screen.

Need to use footage in the same part of the track as the RB (Kemmel straight) for a proper comparison.

Disappointing. So what happened with the constant adjustment to the regulations to prevent dirty air? Forgotten... Brawn left, and no-one seems to be doing anything... It wouldn't be the FIA if it succeeded in something...

So I've had a theory for a long time that the real answer to the spray is make like the Gen 2 formula E cars did and cover the front wheels. With that done, the amount of spray would be massively reduced, as it would lose all the momentum in the arch (this is all very luddite reasoning). It'd also have a net effect of making the cars less draggy and create a new way to use aero without creating outwash, potentially. Is there a reason F1 (and their fans) are so against having covered wheels on the cars? It's seemed a no-brainer to me since the Red Bull Gran Turismo concept from... I think GT4 or so, had covered front wheels. Worth some CFD tickets to put numbers on it maybe? I've love to know just how much of a difference it would make.

Propper content

You chose that title on purpose didn't you 😆

Since RedBull is going in against the spirit of the rules, they should be penalized. This video also clearly explains RB's advantage on how they are able to benefit from their DRS so much more than the competition. the issue here is that if the FIA allows this, then all the teams will follow suit, and you are back to square 1 PRE-22, with a lot of unneccesary money spend, and the whole problem is back. It essentially only worked for the 1st 1/2 of the '22 season. By now, it's all done and dusted. It's reasonable to expect that any reg change will cause this. The real problem however is not that the outwash or aero causes cars to have problems following. That is the genuine thought problem of the FIA. The problem is that following close, with a loss of aero, and increase in heat, can ruin your tires in as short as just 1 or 2 laps. The problem thus, is actually, not the presence of aerodynamic grip, it's the lack of mechanical grip - and this is greatly due to the artificially bad properties of the tires. if the FIA finally decides to use proper tires, that bring proper, respectable grip and endurance, then we're looking at a whole different situation. It will also improve racing under wet conditions. Less aero dependance is not really a solution. It is not the real problem, because you will always turn into a situation that that will be overcome. Mechanical grip is what is lacking, and that mechanical grip should be achieved fully independent of aerodynamics. There are two ways to achieve this, but there are 3 things needed to bring real success, best is 4 changes. The first is, as stated, to fix the tire issues. Make real, good, tires, and you are done. They can keep the different tyre compound mandate if they wish. The second is, to lower the overall curb weight of the cars. Make them shorter, and allow 'exotic' materials. The cost cap makes sure costs don't fly out of reality. A third solution, would be to open up the regs. The cost cap will prevent going too far on cost. but if you open up regs, teams can come up with nifty innovative designs, as long as they fit within safety margins. The fourth solution would be, to re-introduce fueling. This would also reduce the weight of the cars easily by 50kgs. Right now, they ride with 100kgs of fuel on board at the start. The cars are already super heavy. If you introduce re-fueling, by forcing the max fuel capacity to be 50kgs, then this will make the cars a lot faster and much more agile. 'But it is more dangerous to have fuel during a pitstop' - yes and no. The idea once was to reduce incidents because teams were trying to have too fast refueling leading to incidents. But now we have so fast tire changes that it creates such hectic we see much more 'unsafe releases', and it puts many members in danger. forced refueling makes the pitstops slower, and as such, less cost and pressure to change the wheels and make mistakes. It will also take away unfair tactics during safety cars or virtual safety cars to a margin.

So, outwash is still a thing. Thats literally what FIA want to remove from the previous regulation. Overtaking will be difficult if this continue, just like pre 2021 era. This reg need some update to prevent outwash. Maybe smalller sidepod or slimmer floor will do

Spa was boring. First time I thought about turning off the race.

It feels like your just making stuff up to be honest

if this goes against the intent of the regs, the fia should step in and close this loophole. otherwise more teams will figure it out and we will have no overtakes

I don't think this analysis is correct cause you're comparing apples to oranges - dry line vs wet line. They have different amounts of 'visualising particles' so you may not be seeing all that happens in either case.

So is RB going against the rules?

This shows where others lack. Tbh, I think redbull is best at aero. Adrian newey and the team he built is great at aero. Mercedes’s strength has been engine but because of the freeze they can’t do anything with the engine. Fia lost the plot here . They basically handed the championship to redbull . It makes no sense because f1 is more about powertrain than aero. Manufacturers are here because of the engine not aero . Redbull being an independent team has become great at aero as that has been their main focus as they always sourced their engines from outside.

Let’s hope Mercedes can get some improvements done before end of year… I feel the main issue for them would be their chassis design

So, in summary Merc good, RB bad

Crazy how these cars literally cannot race in any sort of wet conditions

Does this mean the secret behind RB19 super pace is because they are not fully complying to current regulations! Somewhat cheating?

pero esa comparacion es media pelotuda, el auto de mc laren pasa por la parte seca y el redbull va por la parte sucia que logicamente tiene mas agua por ende genera mas spray...

Why are you comparing cars and drivers at different positions in the track or in different situations (eg under braking or in acceleration), it's like comparing apples to oranges you can't really draw accurate or correct conclusions from something like this

Send this video to the mercedes engineers so they can fix the donkey

Never take rain into account regarding exact aerodynamics of a car. Water spray from rain goes all over the place and only sometimes helps with vortex visualization, only flow viz applied directly to car surface and itself being a special mixture of paraffin and pigment can show the flow on the car, but not around it. Water cannot really show the flow of air around the car because water is heavier than air and water spray goes all over the place. A nice attempt, but this analysis has not much to do with reality of the exact flow patterns because water spray behaves differently than air. To even draw comparisons between cars is, unfortunately, completely off the mark, as the conditions are almost always completely different. Whether it's the amount of water itself, or the wind, or the condition of the car - such things are completely meaningless. Sorry to say this, nice try, but the conclusions and statements, especially comparisons between different cars are completely worthless. Unfortunately, this is a fact. Waterspray does not make a track a windtunnel. Water is no air.The amount of water always varies completely at any time and the ambient conditions and the car is also never comparable. Sorry, nice as a gag, but in reality completely worthless.

just invented stories, you cannot see anything clear, it is just your interpretation.

So, is Red Bull cars not in the spirit of new registrations?
