Why The Double Diffuser Was (Down)Forced Out Of F1

[@TechnoGuy11]

Yes, anytime I see anything about the "blown diffuser" I'm all in. Can't wait for that episode.

[@PinderXross]

Or the sneaky loop used to lull us here... ;O)

[@user-jh7tm1kn9l]

It wasn't banned It was basically unusable in 2014-now because the v6 turbo hybrids don't produce enough exhaust gasses to power double-diffuser

[@1312_PV]

@@user-jh7tm1kn9l I think the exhaust position has been regulated several times so teams cannot take much advantage of the blown difusser or coanda effect.

[@user-jh7tm1kn9l]

@@1312_PV the v6 turbo hybrids do not produce enough exhaust gas TO use the blown diffuser effect

[@1312_PV]

@@user-jh7tm1kn9l During the V8 era exhaust placement was moved at least twice to basically negate blown exhaust effects. The second time, after the teams started to find some advantage while using the Coanda effect to bring the exhaust gases back to the same position. Currently exhaust exit placement is greatly regulated: 1. Exhaust exit has to be 170-185mm behind the rear axle line. With blown exhaust, they were way forward, Lotus Renault was over a meter and a half forward of this line ONLY to take advantage of the blown diffusser. 2. Exhaust pipes have to be placed with their center point offset +-100mm of the centerline of the car. In the past they were at each side, going towards the rear suspension and difuser area. 3. Exhaust exit has to be 300-350mm above the floor. Considering how far back they are, it is already impossible to point them towards the diffusser area. 4. Exhausts have to be circular, no weird shape to channel the air. 5. The final 150mm of tailpipe have to point upwards at an angle of 5 degrees. They used to point them downwards. 6. Bodywork behind the exhausts is greatly restricted, making adding a monkey seat style wing that benefits from the exhaust's gas velocity impossible to fit. Surely less gas can make a difference, but considering that teams gained around two seconds a lap by the use of the blown diffusser I bet they would still love a couple tenths or whatever was left to squeeze with the new engines considered how hard they are to extract.

Honestly you guys didn't explain at all how the double diffuser actually worked or what loophole it was exploiting. You also didn't explain why it was forced out of F1, which is even worse because that's your title. Also, I swear I've seen the animation of the penny and the pyramid of gold of 6:23 a billion times now, I don't even remember what it was originally meant to represent with how many times its been recycled.

[@parthsoni1230]

It was used in their brawn gp video and described the part where honda sold the team for a single pound and contributed quite a lot of money for further development which would have been otherwise used for winding down the team.

[@Ropius777]

Yeh basically nothing interesting here at all, which shouldn't surprise me it's what i've come to expect from autosport.

[@henrik1743]

CYMotorsports videos are 100x better than this lol

[@joeogle7729]

The loophole was that they could make a hole in the crash structure that allowed them to make a diffuser within a diffuser. The middle bit in the brawn design sped the air up even more meaning more downforce. The bottom line is the car had 2 diffusers. I actually went through the technical regulations to find this for another project. the wierd thing is they didn't actually ban them until 2011 so most of the 2010 cars had them. Hopefully this helps and if someone else comes along to correct me thrn oh well.

[@MyMintus]

Can you make a video Raging?

[@brokenstyx]

Why was it banned? The title suggests some comment on why the double diffuser was forced out of f1, you just said "the regulations loophole was closed" ok yeah why?

[@FullOilBarrel]

It’s autosport

[@Spido68_the_spectator]

@Adrian Matthews No because a diffuser isn't supposed to create dirty air...

[@Spido68_the_spectator]

@Adrian Matthews Why did they want to reduce the diffusers ? Makes no sense

[@henrik1743]

CYMotorsports videos are 100x better than this lol

[@ayshachowdhurt2517]

Because essentially the rule was made to reduce the dirty air for cars behind, the double diffuser even though it technically followed the regulations it defeated the purpose of the rule (since it still created that dirty air) so was banned

[@Bahamuttiamat]

Great vid, but you forgot one important point. Toyota and williams got their own DD not by accident but information transfer. With honda pulling out, exiled engineers joined the toyota team and the toyota powered williams. That is how they inherited their own version of DD. That said, it wasn't the reason the brawn was so fast. It was outwashing front wings. The DD, much like DAS just added to the entire concept. According to paddy lowe, inwashing front wings killed the mp4-24, until the midseason upgrade.

[@fenhen]

This would suggest it was a last minute addition to Toyota and Williams, no?

[@Bahamuttiamat]

@@fenhen Possibly, hence the reason they didn't get the maximum from the concept. Even though both had DD, they weren't as ballastic like the brawn.

Good video, but I didn't get the answer - why were they banned?

[@sindhusojan8225]

For good

[@ventisette.]

McLaren and Ferrari managed to build them and get them working. That’s why. They were illegal but Mosley gave orders to let them go so McLaren and Ferrari would be set back, it was all political bullshit.

[@Bahamuttiamat]

Politics. Same with DAS, incidentally, the same team created both.

[@kuro9410_ilust]

[@FlyingMugen]

I'm very excited for the video on blown diffusers. Thank you for this one as well.

[@SiVlog1989]

It's usually the way the when the FIA make changes to regulations to reduce the potential of specific influences, be they aerodynamic or mechanical, it produces a bigger effort by teams to get some of the effects back. Case in point, when FISA tried to initially reduce the effect of Ground Effect cars in the early 1980's, like removing skirts and having a minimum ride height, they simply used rules trickery to get it back. Gordon Murray of Brabham got the most ingenious solutions, having a device that had the cars be at the minimum ride height with the skirts retracted when the cars were being scrutineered, but allowed the driver to have the car and skirts lowered to exploit Ground Effect

[@streamleazefishhouse]

The Brawn team only used 3 chassis for the whole season. It was a miracle win, and a pure team effort.. I will also point out that if the season was as long as they are now, they wouldn't have won because the car had almost no development and from Silverstone onwards the Brawn car only won 2 races and Button struggled to get heat into his tyres..

Could you also talk about some of the other innovations that Brawn had because the double diffuser wasn’t the only thing that gave them the upper edge. Also a look back at the Honda RA109 the car Honda was in development of before they pulled out and continued to develop even tho they had left F1....

Answer is rule changes. Save yourself from making the blown diffuser video because that also got banned due to rule changes, also V10's : rule change. Wide wings : rule change. Refuelling is about the only one which has a reason other than rule change as to why it's no longer accepted.

I have not watched one single video about F1 without the mention of the FIA banning everything. Its already getting annoying and I just got into the sport. To me it just seems so stupid if another team innovates and designs better than you well than get better. The FIA should've just implemented a spending cap a long time ago. Let the teams innovate however they like within the allotted budget.

[@lespaz1197]

that title joke almost derserves a downvote...

[@mitchtavio]

So why was it banned? You didnt actually answer the question...

[@TheZanzaroni]

In sports in general there is the rule itself and the intent of the rule. While the wording of the specific section allowed the double diffuser to exist its intent was to limit the section and therefore such trickery were eventually banned. The actual reason behind it is that it gave teams so much performance that the FIA was worried on safety grounds

[@advancegalaxy4771]

Ah yes Seb's bestfriend

[@everythingman987]

Why does the FIA ban every new innovation like this? Slow cars with many homologated parts and little to no innovative designs are boring. What kind of sick mentality leads an organization to ban every new innovation that comes along in the sport?
