What Happened To F1's Blown Diffusers?
Vložit

- From 2009 all the way up until 2014 the F1 grid was home to a diffuser arms race, in the hopes of increasing rear end downforce. Once the infamous double diffuser was banned, we saw the rise of the blown diffuser, and eventually the even smarter reign of the Coanda effect exhausts, with Red Bull leading the charge with incredibly innovative designs, even to this day.
While these diffusers affected F1 development forevermore, we no longer see them on todays cars... so what happened to them? Jake Boxall-Legge takes a look down memory lane to find out why they were so impressive, and why we haven't seen these diffusers on F1 cars since 2014.

The lack of blown diffuser sounds in this vid disgust me
like, DISGUSTANG!
This is why I read the comments initially. Thanks, leaving.
Just listen to this years red bull. There's something going on mid corner with the engine map that sounds a lot like exhaust blowing.
@@tnexus13 it's just a normal thing for the Honda engine since their return in the V6TH era. go listen to the 2016 McLaren, have some eargasm.
Just saved me 9 minutes. Thank you SO MUCH!!
Teams: F1 is about innovation to find more performance.
FIA: You have too much performance so we are banning your innovation.
Teams: F1 is about innovation so we can win races and make money
FIA: You have too much performance and that's boring for fans and the show needs to be competitive and interesting in order for us to make money
Fixed that for you.
@@DapperHesher I mean the 80's and 90's had a lot less strict regulations than modern day f1. If the goal was to make f1 more competitive they failed by adding more regulations. I mean there are so few creative ways to catch up to the front.
@@dysonburt3309 Are the technical regulations WHY they're less competitive, though? That's pure speculation. A lot more than just that has changed over the years. The whole thing of crafting the technical regs of motorsport is waaaaaaaay beyond armchair opins in CZcams comment sections, IMO. There were stints of utter dominance in the '80s and '90s because one team had the sauce.
Honestly, budgets and resources are probably far more to do with the parade we see today than weather teams can innovate or not. It's a big assumption that cash poor and less staffed teams would all bring out miracle innovations and topple Mercedes or whatever... or are teams with more braintrust and cash just more likely to pull out the sauce in that scenario? I'd reckon the latter.
Lol the FIA just banned 'Quali mode' settings for races today.
@@DapperHesherNo I never said that regulations make teams less competitve but what I was saying was that when teams fall behind in the devlopment race, strict regulations make it harder for the teams behind to catch up. as well as to make innovations it takes a risk for the team who first designs it so if Merc devolop something new they have to spend a lot of resources to make it but teams that have less resources can copy that innovation for a lot less, in additon to if it doesn't pan out that invest of time and money is lost for Merc which they could have had working on their in less of a risky area for the car.
Banned: The Ferrari engines saga
I think we all know it’s banned
Once there is a budget cap, there is no point for regulations tightening. Lax them all. It upto the teams to decide where they want to use up their resources.
I didn't think of this, this is actually a pretty good idea.
Sounds great till you've got half the field taking wild bets & ending up being slow as Williams, then running out of money to fix it/evolve through the season... & eventually committing to always 'play it safe' going forward
Charlie might happen. What also could happen is teams venturing into unknown territory and then getting a gem on an innovation which can lead to f1 being ” a pinnacle of innovation”.
@@kishorkafle Maybe they stumble across something new, But I really think 'pinnacle of innovation' is much harder to achieve in 2020 than it was in the 70s-90s. The exponential growth is gone, its all tiny marginal gains now, the real innovation (if any) comes within specialised commercialised R&D units some teams like Williams or Merc/Daimler have. Diffuser for e.g. was so specific to just F1. Pinnacle now is more electric/ hybrid on mass scale, things like KERS 10 years ago helped, but we're beyond that now
Charlie again, never know what will be the next “big” innovation. Remind you, ground effect was all a fluke. I am not saying in just aerodynamically or engine wise. It might be the new battery, or chassis material.
They should only ban something midseason for breaching the rule or for safety reasons only. Innovation that still within the rule shouldn't be banned midseason.
Yeah. Imagine putting your team's future on the line to push development within the rules, only for the FIA to decide that they dont like you and dooming you for doing nothing wrong
@@aidanquiett668 Yeah, and what about something like “water-cooled brakes”, which was a less blatant version of cheating? Should that be allowed to continue for the whole season or do you agree with the Parc Ferme rule which caught it out but was introduced mid-season?
@@thethirdman225 things like that are ultimately the FIA's fault for allowing it in the rules, and imo shouldn't be banned until the end of the season.
@@fruitygranulizer540 Well, not really. The FIA doesn’t just randomly make rules. Mostly they do it in response to pressure. Unfortunately, without sounding like I’m particularly pro-FIA, most of what we hear in response is an embedded reaction that has its roots in the FISA-FOCA wars of the 1980s. This is largely a construct of English speaking teams. If you asked the Europeans, I think you’d get a different opinion.
These types of incredible engineering is what got me into F1. I love all these technical marvels and it makes me extremely excited for the 2022 season that will have the potential for so many more of these type of stories!
I loved blown diffusers and am so glad to have seen them for those years. Finding clever solutions is in F1 DNA. Brilliant advances should not be banned but eagerly embraced.
and shitting on them is in the FIA's DNA.
Ok, but think for a second. Blown double diffusers.
Think about the amount of destruction a team could bring with that
@@kotzilla.8_242 ok, but sealing skirts, double blown diffuser with a fan.
Ground effects blown exhaust and double defuser
@@Saxe_AXRL That car would make it through one lap in FP1 before being banned by the FIA
Seb would be unstoppable
Damn the 2014 regs really took away all the excitement from the sport
It was really the 2017 ones. The insane downforce and massive car widths make overtaking even more impossible
Allow all innovations but make sure that the following car doesn’t lose more than 80% downforce.
So: DAS, Blown Diffuser, Double Diffuser, Ground Effect, F-Duct. ALL legal. But still make these cars race able. That would be cool.
tbh that woulld be cool as different team will come up with different idea and making F1 look more different from now
Make it so that if the car gains a lot in an area, then it has to lose in another.
Yeah dont get why they cant just measure dirty air and say that you cant produce more than a certain amount
the fan car would be great.
Or just cover up the wheels. 90% of the dirty air issue is because of all the myriad flow conditioners trying get get the flows around and away from the stupid wheels.
I wanna know about the Banned Ferrari engines
Hell yeah! How the manage to get oil in the cumbustion chamber and mess with the fuel flow sensor.
Well thanks to the FIA we never will. And nor will anyone at Ferrari ever divulge. If they were innocent they'd be shouting it from the rooftops, enough said really.
they were cheats. nuff said.
@@fetusofetuso2122 Aren't they always? Just like dealers having the ability to roll back odometers and the story going hush hush in a hurry.
@@joshfoley8862 if ferrari makes them? yes!
I miss blown defusers, but given how much of the exhaust energy is taken up by the turbo and hybrid systems on todays F1 cars I don't think the gains from using such a system would matter that much. The extra power of the current 1.6 turbo hybrid formula cars makes up for the added down force from the blown diffusers. With a few hunderd more horsepower cars can simply tack on more down force elsewhere and overcome the added drag.
The real problem with F1 is that it now seems to reward incrementalism over large innovation. This really helps teams like Mercedes who can devote a massive ton of people to tiny details. The Red Bull and the Mclaren of old seemed to rely on crazy outside of the box ideas. (Yes i know about DAS)
Renault never got the credit it deserved, but it was the fall guy whenever redbull fail.
The genius of Adrian newey. I think the simulations need to be better visualiSed
renault
Best video guys - thumbs up. Love these technical insight...
The sound was awesome
Reading the comments here I sometimes think most of the watchers have only been following F1 for a couple of years. Banning things is nothing new. I've been watching F1 since the early 70's and every few years something was banned to basically stop one team from dominating or because the cars were getting too fast for safety. The Mercedes domination was the longest period I can remember with no change specifically aimed at stopping it.
I think it's great that they slipped through as they are currently looking into using the underside of the car for even more aero performance to get the cars closer together for 2022 and beyond. I'm certain that these definitely helped them to find possible solutions
Nice breakdown of the concepts!
Another great JBL video! 👍
love this series!
2011 was the best year for the look and sound of f1 cars
Henri Coandă was a Romanian inventor, aerodynamics pioneer, and builder of an experimental aircraft, the Coandă-1910 described by Coandă in the mid-1950s as the world's first jet
FiA always banning innovations. and regarding spending.
Thus a small fraction of viewers may quit on the competition tailgating. And without these Innovations. The cars will handle like trucks or hovercraft. Which puts drivers at Harm's Way
Fia it's actually helping innovation. Banning cool systems it put's those awesome european equipes to invent new systems even better than before you brainlet.
Interesting video!
Tuned mass dumper.. I would love to see this
yeah, what did it look like?
This was done I believe in the Renault R25.
@@sujendrannairtheywaharen2230 yep. This is a series about advances that were banned, so they ask what other banned systems we want to see in a video.
If I get another Formula E advert I’m gunna loose my mind. “Most dominant race in the championship” just what f1 fans need more of
Use adblocker lol
If they had F1 top speeds and used F1 tracks, I'd probably watch it, but I don't really like the slow, tight, street racing
Sadisticsalmon not to mention the fact the sound is beyond shit and the fan boost thing makes the whole series just one big shitty gimmick. I love almost all racing but ill never watch formula E. at least in MotoE, they follow motogp around for the season and its treated as a proper series.
Sadisticsalmon half the point of Formula E is to bring the racing to the people. They can’t do that on actual tracks for the most part. That, and these cars aren’t quick enough just yet for actual tracks.
jamiejosh96 That’s the most relatable comment I have ever read. Thank you so much for getting out exactly what people think!
It'd be cool to see a vid on active suspension as there are rumors of it making a resurgence with the new regulations coming
I would like to see a F1 car with all these technologies that have been banned
Can you make a video about the evolution of the area directly in front of the side pods. They used to be clear of bodywork thanks to the 2009 change in regs then became more and more complex over the years until we got to where we are today.
I want to see the Active Suspension, the Benneton traction control and most recently, the aero parts banned in 2008 (especially the weird arch above McLaren front wing)an the engine party modes.
What about CVT?
I would like you to take a look at the banned electro suspension that would automatically tilt the body according to what turn the car was going in
I loved them and the ingenuity that created them. I remember when red bull figured out their coanda exhaust they ended up going from mid pack in the speed traps to the fastest and therefore the fastest car in all areas
Not so much the technical side but the changes to driver/team communication rules would be interesting
After the past week a piece on the banned qualifying engine modes might be in order
It was banned. That's what happened. But NOT inadvertently. The RB7 was a mega ride in F1 history. Exellent post - lots of great information.
imagine how fast F1 would go if all this things are avaialbe ABS, traction control, blown def, f duct, s duct, slick tire, V12 engine, active suspension, Tuned mass dampers, Gas turbine engines, Rocket fuel and Flexi wings
can you make a video on car design change from 2008 to 2009... in 2008 cars looked so much futuristic and in 2009 they looked very simple..
The chimneys were cool!
Redbull and lotus sound was crazy
how many times will you guys make a video about this. it's beating a dead horse at this point
I want to see more videos on the engines, power output and tech @scarbstech
ooohhhh its not blown like a damaged term like a blown tire. its just the exhaust blowing on the diffuser lol. good vid
Everything Diffusor related, especially something that stabilizes flow, rather then adding downforce is welcome And should be allowed as it makes cars more raceable.
You forgot the best part of blown diffusers. The epic sound
People have to understand that while it’s really sad to see incredible innovations being banned like this, it’s for good reason. If every innovation wasn’t banned we’d have cars that are too fast for humans to drive. And even if humans could drive them, the risk of injury or death caused by crashes would be much much higher.
The tiny rear wings in the center over the brake lights always make me laugh.
3:06 no wonder the car caught fire twice in a season
All those resource points put into chassis only to have the reg changes kick them back down the performance charts.
3:50 What were they trying to do with the 2012 regs than caused them to inadvertently ban blown diffusers?
8:16
Why is it not viable now?
I know Regulations this and that and so on, but is it because the v6 isnt as strong as the v8 ( I mean just engine wise without the hybrid part).
As he said the cars exhausts have to go through the center line of the chassis now, so it’s not viable
would love a look at the twin chassis lotus
Well, that was outright cheating. I think they did an episode on it.
Possible to combine ground effect with blown diffuser?
Ground effect vid please
I miss the sounds of the blown diffusers
I think that the only things that should be banned should be on safety grounds. Other than that, just regulate the way you can use an effect. If blown diffusers offer a performance advantage, let the teams use them if it does not also pose a safety risk. Then if teams start throwing too much money at it, regulate it so it is more uniform, but not so that it eliminates the innovation.
I want a race between Ferrari 2019, Redbull 2012, Williams 1993, merc 2020, and Ferrari 2004 with Bridgestone of course
Active suspension from 1982 to 1993.. tell us about that saga.
Where do you get all the drawn images of aerodynamic details from? Would be good to know a source.
Giorgio Piola does them. He’s been doing it for over 40 years and he’s published a lot of books.
I love the fact that fia didn't ban blown diffuser they just make it impossible to do so,so technically the technology is still available if any team had the balls to do so
I with that I had lived the Motorsports technology boom in the 70's & 80's. Although the music, fashion, oil turmoil, & road cars, not so much.
does anyone know how the exhaust gasses exiting before the rear tires didn't heat overheat the tires?
Good question. The idea of Coanda is that a turbulent flow will remain attached to a surface for longer than a non-turbulent one (I’m reluctant to say laminar because it doesn’t apply to F1). I guess from this that the exhaust gasses would stick to the a Coke bottle waist of the car and exit between the tyres and the inner fairings.
❤😀🇬🇧. My mk1 mx5 used Helmholst resonance for the intake. Every 2 sroke since the MZ's uses a tuned expansion chamber (thanks Ernst Degner).. Then Yamaha, with its YPVS variable port timing. With several other cars/bikes using variable intake lengths . Less complex than phased VVT cam profiles. Now its possible to have complete, independant control over valve timing and pre ignition of a richer mixture, seperately, which ignites the main charge. We've come a long way from the side valve, OHV, HEMI, and Susuki' TSCC's.
Less rules more innovation...please.
Why did hybrid era have to put the exhaust in the middle?
to stop benefit of hot air, plenty generated in FIA meetings
I loved the V8 Blown Diffusers
I think this is the reason why Vettel spins so much and why he's never hit the Rebull heights. He needs the rear grip.
Bring it back for 2022 please
@LCP71 it’s also incompatible with the new aero regulations.
I miss the blown diffusers.
You keep showing alternate pictures of Lotus-Renault and Team Lotus (Caterham)…
Repost?
F1- we have listened to the fans and they want ground effect back
Fans- BLOWN DEFUSERS AND V10S
F1 engineers are so smart they could probably cure covid 19
@argh666 there's always that one person who takes the comments to literally 🤦
Bring back the fan cars.
these innovations were seen as awesome and fun, exactly what the FIA doesnt want.
Active suspension. It's madness that they won't allow this. It would revolutionise F1.
Imagine active aero
Active suspension was flat out dangerous when it malfunctioned.
Cars would completely bottom out when the system failed and it was essentially a death sentence for the driver
@@cuscoothriyas5163 Given only one F1 car has ever used active suspension, and that car won both worlds championships before it was banned, and all this was using computer and actuator technology from nearly 30 years ago, I have to say, on reflection, that you are talking absolute bollocks.
@@cuscoothriyas5163 That's exactly what it was doing, particularly in the case of Williams. They were essentially slamming the car onto the ground to stall the underbody and lower drag on the straights, then jack up and pitch the car to make the most downforce under braking and in the corners. It was really just making the car one big active aero device.
@@DapperHesher Not really slamming the car to the ground per say. When they were used they had to be specifically programmed for each and every circuit or it would bottom out and flat out render any control of the car moot as it would lift one or more of the wheels above the floor of the car, essentially making the car a sled you can't steer.
That said with computing having come as far as it has now and with fuel concerns at an all time high, now would be a good time to reintroduce it. Perhaps it might minimise or even negate the need for big wings which would cut drag down by quite an amount.
Those 2011 cars sounded all by themselves .
Next on banned quali party mode
It's so funny when looking back how dominant RB and Renault combo use to be, and once 2014 rolled up RB told that Renault engines are sh*t and they will leave F1 if they don't get Merc or Ferrari engines.
Sadly they didn't, as usual Marko never keeps his promises.
Can someone do something about the formula e ads please ,and how's about the Flexi wings that was used in the early 2000's as they were interesting
FE season will conclude soon. This is just their season finale.
I don’t understand why they would ban any of this
Look into the blown wheel nuts
I want to see FRIC
Why does the honda hybrid turbo era engine growl off throttle on over run ? Its always done it and has become more prominent again ?
The brabham fan car please
Aidan Millward has literally just done it here czcams.com/video/EaWkHI584bE/video.html
Forgot this happend
Wonder what the engineers will think of in 2022
Caught wind lol
when are we going to see these aerodynamic technology being used in road cars particularly to help minimize gas consumption.
Already use, compare with old car from the 60'/70' to modern car you can see.
Truck design too.
Gordon Murray's T.50 is about as close as you get, blowing infill into the Kamm tail area to drop drag during straight line performance. Blowing the diffuser itself likely creates more drag with the flow attached not the other way around.
Free development era.
Free ice cream.
Why did fia wanted ban anyways?
I think the hybrid era ruined f1 for me. Maybe that's just because the 2012 season was so magical.
I've waited 4..No, 5000 years for this post
Why does the FIA always want to ban innovations in F1? Serious question.
These things are done mostly in consultation with team engineers. The two biggest concerns are speed/safety and financial viability. Look at the way the 2021 regulations have been formulated. Look at the rules for the Coanda effect. All of that was done in consultation with teams. And that was all teams, not just Ferrari.
Notice how all the teams involved didn't directly copy another teams design not like a particular team now competing.
Tracing point seems a bit fishy but fucking genius. The only challenge for them now is to understand the car. They may be able to copy something but if they don't know how to use it, it may as well be chucked in the bin.
damn FIA
i wish they would open up the rulebook a little more
I wish they’d go to a spec formula.
@@thethirdman225 nah that defeats the whole point if F1
@@TheJGJR9 I know, I was being sarcastic. But if F1 is to survive, they will have to move increasingly in that direction.

It’s could be back 2026 new powder train lower high-put 1.6 L to 1L maybe 2 stroke in near future well exploited it’s a cheap way to increase downforce and the sound very radical too
Who's here after Mclaren's video on Silverstone?
