- Hahaha, blown diffusers go bbbbbbbrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrpppppppppppppppp
But not strictly a Red Bull invention. It had been tried before in the 80s and 90s but fell out of favour. But when Red Bull and Renault managed to get the exhausts to blow on throttle idle as well as while on the throttle, they became THE thing to have.
So how did it all start and how did it work? Let's have a look.

I like to think the blown diffuser sound is just a TH-cam video of an A10 gun sped up.
**BRRRRT**
Heidfelds sidepod exploded in Hungary 2011, his last F1 race
Gotta love the BBBBRRRRTTTTTT
F1 goes **BRRRRRTTT**
nah, it's the aforementioned GAU-8 but in slow motion
Speaking of driving one-handed, Schumacher spent a lot of time racing one-handed as he was constantly adjusting the brake balance wheel multiple times a lap.
I remember seeing onboard footage of him doing that and literally found it insane how he was able to do it all, but then remembering where his racing career started, along side how he raced Mercedes prototype cars at Le Mans too, he had probably perfected one handed driving already much prior coming to Formula One.
@@Cynderfan35 also to mention the era that he made his f1 debut was like a bridge between the tradition h pattern one and semiautomatic(modern era).
😊
@@Cynderfan35I mean I don't think formula3000 went to sequential transmissions until the late 90s, so the whole field knew how to drive one handed with a 6 speed while messing with biases and fuel mixtures. Schumi, rest his soul, really expanded into the inter-corner differential/traction control adjustments which is pretty ground breaking at the time.
Interesting side note: Martin Brundle broke his left leg in a sports car accident and when he came back to F1, as all the cars were going sequential, he was one of the only drivers who still right foot braked as he didn't have the strength in his left leg. Always wondered if it kept him from getting a win
The teams used their hands to control the F-duct because the safety cells had all been homologated at the start of the season, and they couldn't change it mid season. Only the Mclaren tub was homologated with a vent flap hole down near the leg.
Newey. I never cease to be impressed by his mind. He's done it again, as far as Gary Anderson is concerned over at The Race. I read a piece over the weekend where he went over how the whole rear of the Red Bull car, not just the DRS, is optimised for drag. So where Lotus/Team Enstone and Mercedes wound people up with Double DRS a decade ago, now Red Bull bring us... Triple DRS!
I like Formula 1 and engineering, and when...
I wouldn't be surprised if something with the rear wing is also stalling the diffuser when the DRS opens.
Gary Anderson is about as clued up about Modern F1 aerodynamics as your average primary school student. The man worked in the industry before computation fluid dynamics was even a thing, I wouldn’t really trust anything he has to say on the matter. In the industry there’s a well known phenomenon called the inverse Gary Anderson law, the idea being if Gary Anderson says something then you can normally assume the inverse is true.
The main key to Red Bull's current performance is the way the highly intricate floor and suspension interact to produce the same amount of downforce that other teams can only achieve by running big wing angles or running the car so close to the ground that it causes porpoising. On top of that, there's some aerodynamic magic happening between the beam wing and the DRS system opening, that increases the effective drag reduction on an already low drag car.
I’ve been going through your old videos (as I am a new subscriber and new fan of F1) and I wanted to thank you for turning me on to Adrian Newley’s “How to Build a Car.” Its a fantastic read. Did you ever end up reading it?
I used it as a textbook today. That’s the first time I’ve had to actually read it.
It’s a chonky boi of a book.
I ended up reading it in less than an entire weekend, and it was probably the only time i noticed these weird language devices that i have to learn about in A-level English (i currently have to go through that torture) because usually I find the texts in class to be this boring that i cant notice these bloody terms…
Anyways the book is a MUST READ and if anyone here really doesn’t want to spend money you can find free PDF versions of it online.
I loved the f duct. It was like the last hope of the old school McLaren fans. The team was great then. Remember CarTooned? It was a fun team to root for.
the good old days. Plus I think McLaren always has something about it kinda like Ferrari, just different. I hope McLaren have a resurgence.....
It is amazing how much work renault put into this (and the engines up to 2013) only for horner to slag them off in 2014. The Coanda effect used on the 2012-13 cars was just as impressive
IIRC, Red Bull had already voiced concerns about Renault in the V8 era, because they were already down on power compared to Mercedes and Ferrari, but as the engine was still good in driveability and Renault were very flexible they still found the relationship to be a good one.
It all went to hell when the hybrid engine was found to be performing poorly *and* unreliable.
@@Olivyay, I don't remember them actually commenting on the engine and not praising them.
Yep classic case of them focusing on the V8 at the request of Horner while not putting development into the hybrid.
Pedantry here but I think Heidfeld got lightly shot by his exploding sidepod in Hungary, not Melbourne. Great video as always!
Lotus’s front-exit exhaust is one of those things that I always hope will work, so that it upsets the order, but doesn’t.
Let’s hear it for kooky ideas.
Then they tried the tusk nose.
Heidfeld’s side pod blew up in Hungary.
Oooh... You just sneakily debuted some new jazz.
these cars sounded awesome under braking. i loved the renault in the rain blowing water out sideways from the car. so cool
They're not "loopholes", they're "Easter eggs." Adrian is the best egg hunter that F1 has ever seen.
"Surprise development mechanics for sense of pride and accomplishment"
then there was a happy conversation between Paddy Lowe and Newey about the coanda effect to still send some weaker exhaust gases towards the general floor area. Vettel also just trailed a bit of throttle with perhaps some clutch actuation to get around the cold and hot blowing bans. Great times for a Sebastian Vettel fan like me.
I knew Olivier Panis had a blown diffuser, because his engine note when he won at Monaco on 1996
I had a look over Mr Newey's historic racer. It's incredible. There's components doing three jobs at once! I swear, if a bird shat on it, he'd notice the change in balance!
Finding loopholes is a key part of motorsport, see the loveable rogue Smokie over in NASCAR.
A great storytime episode, go find it, its worth a listen.
football in the fuel tank , and 2" fuel hose 10m long stuff in Nascar..
Honestly, besides actual race day, this is my favorite part of racing, especially F1. Finding a way around the rules. It's kind of a lost art here in the US with Indycar and NASCAR, now that they are essentially Spec Series. I miss the days of a Turbine engine showing up for Qualifying at the Indy 500 or some manufacturer designing some crazy car for the retail market, so it qualifies to run in NASCAR. At the end of the day though, it makes me happy to know there still is a cat and mouse game going on.
Great channel. Always enjoy your videos and the effort you put into making them. Thank you.
Heidfeld's exploding lotus was at the Hungarian GP 2011
awesome video remeber this era well
I remember standing at pouhon Spa in 2011 when the Lotus with the forward facing blown exhausts went past it sounded crazy
Great amount of views in the time
Can’t wait for people to start watching all your productions
If I remember correctly, the ban Newey refers to in the 90s was having the exhausts themselves in the diffuser, not blowing over it or beside it between the tires and diffuser to combat tyre squirt.
0:50 good impression lol
That 2011 Lotus sounded beautiful. There’s a short video of it on yt.
6:43 nice reference
The 1992 Galmer INDYCAR had a blown defuser. They talked with the designer of the car on the Marshall Pruett podcast. It’s why the car was great on street circuits but had way too much drag on the ovals.
I just love how the best approach to designing anF1 car is essentially to "Air Bud" it. If the rules don't explicitly forbid it, it's fair game!
It was interesting, I've been rewatching the 2011 season (rewatching Seb's dominant years since he was my favorite) and the first year of the DRS was at a point where it wasn't a 'free pass' system because the rear wings were so narrow back then, and the DRS slot was very small. It worked better than it does now imo, and I wonder if 85mm is too big these days and should return to the 'letter box' style.
That mixed with the blown diffuser sound was super cool!
Should've gone a bit more into detail for 2012-2013 at the end, not off-throttle blown but still the coanda effect was smart.
Hey Aidan , I love it when an F1 Team comes up with some crazy thing , it may only gain a tenth, But is cool technology ,,4 front wheels , fans on the back,,etc..
What's your thoughts on that ??
Great vid as always! So will the next one be on how redbull lost out a lot early 2012 but then somehow got it all together for the latter half pf the season (at least for seb)?
The original blown diffusers requiring actual physical exhaust pipes running to the diffuser and not just aero wizardry like the 2010’s versions were banned mid season in 1994 if I recall correctly.
The Williams one was the best one (it was their front wing that kept stalling that made the A-spec FW16 such a beast to drive).
The Benetton one was a bit more delicate. The downforce it generated was a lot more binary and it was thus hard to get it switched on unless you were a confident left foot braker, allowing you to keep the throttle open mid corner with more precision.
Schumacher was, Lehto and Verstappen senior were not. Lehto’s neck injury pre season was as a result of a smash were the B194 basically just snapped on him at speed…
As an engineer currently working in F1 I would just like to point out when people use terms like ‘newey found a loophole in the regulations’, ‘newey had managed to exploit a hole in the rulebook’. That isn’t really how it works.
Those loopholes where not found by Adrian Newey. They would have been found by an aerodynamicist assigned to working on that specific area of the car.
Every F1 team, including Red Bull is a team of 500-1000 people. A team like redbull has an aerodynamics department of over 100 people not just an Adrian Newey. I know from friends who work at red bull that Adrian Newey is an extremely good leader, he’s good at pushing overall concept directions based on data and suggestions presented to him and most importantly he understands that aerodynamics is king in F1 and commands enough respect from the entire technical department to dictate compromises in the name of aerodynamic performance.
What people don’t realise about modern f1 is the level of detail which goes into every tiny thing on every car. That blown diffuser program by red bull was likely the result of 6 months work by a team of maybe 15-30 people compromising of external aerodynamicists working on the area, internals and cooling aerodynamicists working on the cooling, composites guys, mechanical engineers, system engineers etc etc etc. Getting the concept to where it was on track will have likely taken 3-4 wind tunnel programs compromising of maybe 5-10 30 minute runs. It will have required installation of systems on the wind tunnel model to simulate blowing at different exhaust flow rates. A lot of very clever people will have worked 60 hour weeks to get that concept over the line and transform it into a race winning car.
It can be very easy from the outside to point at one person (wether that’s Adrian, James Allison, brawn or even Dan fallows at the Aston team) and think they are entirely responsible for the fortunes of their respective teams. To some extend this is true, but it’s often more from an organisational, cultural perspective rather than those guys coming up with the ideas themselves. For every Newey there are a hundred engineers who work their asses off to make a great car and they deserve their praise when things go well just as much as the front men.
I wonder what broke at the culture of Mercedes, recon books will be written about that one
Yea but no one gives a fuck about some random aero guy who worked his ass off and showed newey the potential gain. Lol be real my guy, he gets no credir because he is replaceable
I think we found the guy who actually found the loophole that allows this year's Red Bull to be so fast :)
Been waiting for this one ... Thanks can you do another one on flexi wings esp rb6
I remember at the start of 2009 much of the conversation was “after two poor cars in 07 and 08, has Adrian Newey still got it?”. Yep.
love the v8 era. literally peak F1
I think the Lotus-Renault sidepods caught fire and blew up more than once, the one that sticks in the mind is Hungary. That happened to Heidfeld then they fobbed him off for Bruno Senna, which went well.
I was expecting that Coanda effect to be mentioned around 9:30 but I guess that's a video for another day!
8:50 thats spark cut, i had that on a car and it sounded awesome lol
Will be interesting to find out what the 23 Red Bull has that makes it so much faster. Something around the rear end stalling it at higher speeds.
7:37 close, it was indeed heidfeld, but it was in hungary and not australia. though i believe, and don't take my word for it completely, but i believe that the explosion was caused by the KERS battery, and not lotus renault's backwards exhaust design.
The Renault/Lotus R31's exhaust exploded twice, once in Barcelona and once in Budapest.
Memories
Hi Aiden, great video. Could you maybe do a video on the 2009 rule changes where they banned all of the aerodynamic fins on the cars to make them smoother. I believe the aim of this was to encourage overtaking but it would be interesting to look into the stats to see if the rules worked. Redbull ended up winning 4/5 championships that year and McLaren and Ferrari, sent into a spiral of decline which they still haven't left. Also maybe look at which cars were faster pre 2009 or post 2009.
Newey said in his book that Graham Hill died in a "(Racing) related accident". Not in a race.
Yes it was Nick's car the the power unit failed, i rember seeing the left side side pod blow out just as a Marshall was running by. Something from the car hit the marshal as he passed by.
Not sure if someone has mentioned it but wasn't Heidfeld exploding at Hungary? It was his last ever F1 race and he was sacked straight after.
Hallöchen💫
I loved the sound of the blown diffuser. What racing cars are supposed to sound like :-)
The Al-Gore-Rhythm 😅
I'd guess that 90% of the rule changes in the last 30 or 40 years have been because someone found a loophole.
My comment is for the Algor mortis FWIW
First..for the algorithm
Coanda!
4:55 with schumy left brook braking in a H pattern car, was he using the heel of his left foot for the clutch?
In 1994 he’d have had a flappy paddle sequential so need for heel toe.
@@AidanMillward so does this assume most drivers were still right foot braking even with paddle shift gearboxes?
@@hamdanali2036 The younger guys were able to switch, eventually. Coulthard was still right foot braking up until about 97 or so, whereas Barrichello took forever to convert. Some of the older guys who were so used to the old three pedal system still braked with the right foot, and it might have been part of the senna not being able to figure how Michael was so quick thing. Becuase Michael had it mastered so soon while Senna couldn’t get his head round it.
@@AidanMillward makes a lot of sense 👍🏾 i wasn’t born yet lol, ‘99. thanks man
Is this why they made the exhaust only come out of one pipe under the rear wing and far away from the diffuser?
Yes
I loved the sound of that Renault. There was a pundit who said it sounded like a tin man pleasuring himself inside a metal barrel...
Some beautiful music here: th-cam.com/video/BmGgvHflXgc/w-d-xo.html
imagine a blown double diffuser
That’s what the 2010 car was.
Serious question: Why do things that make the car go faster keep getting banned?
Al Gore rythm lmaooooooo
Wait what's this Mercedes double DRS?
They were stalling the front wing as well as the rear wing. Or something like that.
Funny how people say this was just the car seb is one of the best all time no doubt in his prime same car only man I can see beating him is senna himself or Schumacher
Seb loses his god like rear diffusers and starts spinning.
@@AidanMillward sorry but simply can’t blame just the loss of the bd that 2019 Ferrari chassis was a dog same car he most of 2010 he was behind in the chip 2012 was a dog I think he dominates hami boy in the same car
@@845_Mk6 you were doing so well until you said “Hami boy”
Plus didn’t see Kimi looping it every other race. 🤷🏻♂️
@@AidanMillward lmfaoooooo appreciate your time keep up the good content agree to disagree!
Al Gore rhythm 😅😅😅
If it's so good in F1, why hasn't it made it into road cars? God knows I could use more rear-end grip at motorway speeds.
They had to recall the Gen 1 Audi TT to fit a rear wing as it was unstable at over 70mph.
I wish I had a degree in aerodynamics and/or thermodynamics to understand half of this lol. These car designers have more creativity and ingenuity in their dick hairs than I do in my entire body.
The sound was rather silly, I'm glad it's gone Example: th-cam.com/video/BmGgvHflXgc/w-d-xo.html
