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.
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.
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.
@@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 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.
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?
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
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.
@@assettodrifters1556 idk what actually is in the Ferrari engine as Binotto said it was closed confidentially as they don't want to release their engine mapping to the other teams but the 2020 engine is promising and puts more speculation because of the slowness of the car
@Matt Horkan mercedes is brawn , its a team that was owned by mercedes and changed its name but all the knowledge and experience of brawn gp members is used now on the silver arrow .
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.
I did a bunch of digging yesterday for any and every kind of video about this exact subject. Today. They just happen to release one. I’m now sure I’m in a simulation.
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
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..
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.
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.... Racecar Engineering has a article about it but I would love a I depth video about the car.
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.
“Its all about bending the rules and how u interpret it” and yet people claim so boldly that ferrari cheated with their engine lol. They found a loophole/grey area that even the FIA had problems where to really situate the “innovation” found by ferrari.
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
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.
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?
This channel would be better with an actual nice voice-over artist to listen to and better background music. Autosport videos just sound so bland, monotone and boring.

I remember that year. One of the years I legitimately did not watch. I don't mind watching F1 now, with the current Mercedes snorefest, but watching rampant exploitation of a rule's wording is just scummy. To this day I firmly believe nobody involved in the project deserved any of their success. You can't change my mind.

Politics. Same with DAS, incidentally, the same team created both.
simple: politics forefront before innovation

Its awesome to watch 🤩🥰
1:22 Did you notice how all of them have the Bridgestone B.
New F1 fan here: Those wheel covers were for brake airflow or wheel protection?
just better aero, the covers reduce the drag & turbulance on the wheels
@@aaronfox942 so im guessing they were banned too ?
@@sporehux8344 yep, banned in 2010 for safety reasons after a few instances in the previous year for the covers coming off at high speeds
wheel covers reduce drag thus higher top speed.

It should be allowed again to make small teams more competitive
