This has to be the most excited I’ve been for future regulations

Things to do before dying: - travel the world - play bannerlord - watch 2021 cars running

who called it ground effect and not "downfloorce"?

i'm no aerodynamicist but this video was so well explained i kept thinking "oh okay that makes sense"

Hail to the mighty Chain Bear!

I'm pretty sure the somes teams with find a way to by-pass these proposals and come up with something totally different.

Getting rid of DRS and the ridicilous wing structures? Sounds plenty good.

i know its old news but just how cool is it, that we have an independent youtuber working with a massive outlet like Autosport?

Adrian Newey must be getting excited about F1 again. Max would be smart to stay at Red Bull

Your diagrams, images and animations are very explanatory. By using gifs, your commentary is made more effective, so a novice viewer can easily understand physics that, for a non-driver, may be hard to understand. This has greatly increased my understanding of F1, and the changes in 2022 that I did not 100% understand, but now have a better grasp. Thank you very much for making this video. I look forward to watching more of your content.

This is exactly what is needed for better racing.

The last time I was this early Hamilton and Bottas were still 1-2 in Hockenheim

Finally, "Autosport" has hired a "real analysist".

Did he just say "downfloorce" at 2:00? 10/10 pun if so.

So aero attached to the uprights and moving with them , somewhere Colin Chapman is having the last laugh... 1.5 chassis F1

OK Autosport, don't ever upload another technical video unless Chain Bear does it.

The team that gets the ground effect right will win the 2021 championship

Now we just pray that the FIA and F1 stand their ground against top teams who probably aren't keen on the idea of closer racing

These cars if they work as expected could be amazing and able to race closely for the first time in over 20 years

thank god it was chainbear explaining this

F1 should start working with you to explain these concepts to fans

As a graduating ME student, I really appreciate the perfect balance in your explanations between technical info and simplicity. Gorgeous graphics and great pacing in all of your videos. Really enjoying all of your content. Thank you!

2:47 I think you need to explain why speeding up the airflow leads to a drop in pressure. Non-technical people may feel it is not quite so intuitive to conclude this, I think. Simplistically people might think the "squeezing together" of the airflow would densify the air and make its pressure rise according to the p = rgh formula, where p is static pressure, r is the fluid density, g is the gravitational constant and h is the height of fluid above the pressure probe. (Weather presenters often quote this formula so it is known to many) Of course in fact air is not very compressible so the density won't change that much at the throat. The real reason for the pressure drop at the throat is the interplay between fluid pressure, speed and vertical level along a streamline. Bernoulli derived an equation for this: p/rg + sqr(v)/2g + z = constant. This implies that as the velocity of air increases along the same horizontal streamline, its (static) pressure decreases.

The graphics, and careful explanations in this video make it a joy to take in. Said another way- I loved it. Well done over there.

That ground effect might be the thing that finally keeps drivers from abusing all the curbs.

Excellent video, thanks for clarifying ground effect.

Great video, the explanation was simple but not superficial, very nice

They say the car will only lost 5%of downforce That is too ambitious

F1 2021 is gonna be like mid to late 90s champ cars with those floors. This is gonna be sick

Love these "Chain Piola" / "Giorgio Bear" videos 😎👍

Extremely well put together and interesting video. Well done.

Great video, very well researched and presents the info in such plain language. nice

The 2021 cars are gonna look fantastic with the sleeker and simplified bodywork designs.

Just remember Villeneuve vs Arnoux 1979 French Grand Prix. That's the type of racing ground effects can cause.

The animations on these videos are so painfully simple, yet extremely effective

So well put together, great video to explain this

No more vortices flying off rear wings? Those look so good on tv

Good explanation of the new design rules. I look forward to seeing this implemented. Hopefully, it will work as expected and make passing less artificial and more the result of grip, power and driver skill in making the best of it and another driver’s errors. DRS tends to make passing another car more of forgone conclusion. While I understand why DRS was necessitated due to the over reliance of wings to create downforce, it always seem to be a very flawed bandaid solution to the problem.

Me watching this in 2022.. you basically predicted what the cars would look like with your drawing at the end of the video, great job 😄👍

Good summary and explanation. Thanks. 👍🏻

FIA : Were bring back ground effect DRS : Am I a joke to you ? FIA : Yes , now jog on LMFAO

Chain bear just hinted that DRS could be eliminated! That will be awesome and history will remember current F1 as the dark days of artificially enhancing overtaking rules.

This needs reupload. It is so much more relevant now. Thanks!

Brilliant stuff, thankyou so much. Subbed!

These videos are exceptionally good.

I'm putting my money on RedBull for 2020.

Fantastic video. Keep up the good work.

Diffuser skirts attached to the suspension arm / brake duct structures is the kind of exotic yet philosophically simple(?) space magic F1 needs. Watching the slow motion shots of of these things plowing through kerbs is the kind of thing that would make us racing fans moist.

I'm excited for it. "Make F1 competitive and entertaining again."

Guys I really hate that plate cover on the rims. Hope that they will not include in the regulation.

From now on... let Chain Bear do everything. This was awesome !!

Really great explanation of ground effects! Love it!

We need Lotus back in F1

while closer racing is the objective, it never seems to either last, or be truly realized as two or three teams run away from the field.

Chainbear explaining stuff with Giorgio Piola illustrations is immediate Kreygasm

incredible job explaining this! high marks

It’s all about the WEC and Le Mans 2021 with the hyper car category. the Aston Martin Valkyrie and its 6.5l v12 it’s going to be mental

Thanks for this😁 I just hope the proposed changes actually work the way they're expected. Close racing is what we want😁. Also, is there any news on the engine regulations to be used for 2021?

I waited 12 days for this to be on Chain Bear's channel but I guess I'll have to watch it here now.

i've seen the term before but never really knew what it meant, thanks for the video ^^

I hate how the ground effect term is thrown around with ignorance in forums and on csome yt channels Ground effect is not banned...because diffusers are still legal and the floor still produces over 50% of the cars downforce. What IS banned are sealing devices such as sliding skirts which would drastically increase the amount of downforce from the diffuser

Ah! So that's how they're going to do it without the track damaging skirts

Great video, well thought out. This looks promising!

I'm so obsessed with ground effect, I've watched this video more times I can admit. Great vid.

If Ross Brawn’s study of bringing back refueling for 2021 is approved, we might see smaller cars like those back in the early 2000’s

I'm feeling for the sofa team, CB runs rings around them...

Great video Chain Bear! CAn I ask whatsoftware do you use for your animations?

What a fantastic explanation! Thanks so much!

The main question is whether pirelli can produce a tyre that's work properly

I shall attempt to contain my excitement with cynical sarcasm: I for one welcome our new fully-unsprung "really freaking stressed out member" monocoques.

wow an explanation of the venturi effect that actually explained how it works. Thank you i finally understand it.

Great video. As a long time but casual fan (I don't take notice of tiny aero package upgrades and the like) this explained it really well. F1 has some amazing talent right now and of course there has been some fantastic racing lately, but 2021 regs seems like it will unlock "real racing" again. Rather than DRS passes we should have much closer wheel to wheel racing even through corners leading to passes in new places we might have seen far less of currently. Now we can watch drivers competing even more fiercely, and one mistake will compromise you more now than perhaps in the past because your competitor will be right on your tail at all times and not hanging back to keep the superior airflow, and then relying on DRS to close the gap.

Why can't they just make a rule stating that a trailing car of predetermined design must be able to generate a set amount of downforce? That way it's up to the car manufacturers to fix the dirty air problem.

This is all in theory. F1 has a great reputation of hyping us up and then the teams find loopholes and someone will dominate and we are left with the midfield fighting close while one or two teams are winning. We’ll have to wait and see. Seems interesting though. I do look forward to seeing the teams interpretations of these new regulations.

I know nothing about physics and I was still able to understand all of this. Incredible explanation, thank you!

That really was so informative - well done Chain Bear! I really can't wait for 2021. In fact, I've always wanted ground effect to return in some form or other. It's also exciting in WEC with the Hypercars coming in. 2021 could be the year we all remember as the year of the motorsport revolution.

Sooooo, F1 just copied the current Indycar. Which is fine by me because they look great and the racing is phenomenal.

2:00 ...generate downFLOORce

DRS is planned as a possible workaround; it has been incorporated in the design but not "activated". The place where to put the mechanism is thought of and the overall "default" wing design is easy to change to have a DRS. So it might make a sudden return between seasons. Pretty much everything i've seen from the new rules has been great.

I remember the downforce days, don't remember seeing it at the time, but when they first introduced it had mechanics covering wings on cars to distract from real reason for corner speeds. Later there was the huge fan fitted to another car, to increase pressure differential under the car, which was like following turbo charged road gritter. But as you alluded to, safety wasn't as great a concern in those days, crashes could quickly turn fatal. But the new rules hopefully will reinvigorate the sport, while being safer for the drivers.

we need grid girls back from 2021

All of todays F1 cars currently use ground effect.

2:47 our reliable old friend Bernoulli's Principle

Great video. I wish that you had acknowledged the fans that may teams were using to create suction under the body of the car. You even had an image of a red car with the fan on the back. That is a big part of the downforce ideas from back in the day. also part of why they had the big block off plates on the sides of the car. It wasn't just the venturi effect but an actual vacuum created by the fans. The image of the car with the vacuum fan is at 3:55 for those who want to see it and understand what they were doing back then.

Gotta stay away from them kerbs then

Ed Straw: We must not look at the past to solve the problems that we have now.

Very well explained, thanks!

I watched like a half dozen videos on this and this video was by far the clearest and most detailed. Most other videos didn't even explain why the new ground effect was safer. Thanks for this!

And Indycar says, "You're welcome."

F1 taking a page out of Indy Car's book.

I would really enjoy a video discussing the difference between Towing and this lack of downside caused by turbulent air. Every time I hear somebody talk about a lack of downforce in a trailing car I just keep thinking isn't that something we want so that you can pass on a straight? I mean that's the whole idea of slipstream right? Or is this turbulent air different than slipstream?

Another problem with the oldschool ground effect cars was the suspension. That was made rock hard to keep the car level and maintain the area of low pressure. As a result the cars were extremely uncomfortable to drive. Colin Chapman tried to solve this with the dual chassis Lotus 88, but the FIA was having none of it. Nice to see the lessons learned from that car are being implemented now though.

No wheel covers please !!! 😳😳

So now redbull will dominate again!

Great video! Very well explained - Thanks.... (I came here via wing in ground effect research - LOL)

Another great content, Chainbear! It makes me excited more about the 2021 season!

I don’t want the wheel covers back. They looks so stupid, I know it’s for the aero and so on but still make it look great all around and not put some Prius wheelcovers

F1 teams watching this to develop their 2021 car leave a like

Chainbear is the only reason why I'm still a subscriber to this channel.

I'm looking forward to these changes!
