Thank you.
I love the compressed and simplified info here. well done
Matt Parsons information compressed and diffused
In 2 minutes I have learned more than from all those countless vague explanations throughout the years that I have never really understood.
Thanks Marc
My Golf Gti has a pseudo diffuser, thus ensuring that the back of the car is constantly filthy!
😂
@David Brackin my car emits pure oxygen!
@David Brackin Elon Musk, no thanks. I may have fudged my figures but there will be no buy back!
Didn’t think I’d like this, but after watching it, I’m sold. F1 tech in around 2 minutes, all you need is a sting and a end card and it’s done. Don’t matter if the video is 3 minutes long, as long as the content is around 2 mins it’s a killer concept!
this is what i call an educational video
Very nicely done👍 funny ..rushing through those last 6 sec🤣🤣
As they saying goes “ keep it simple.. Stupid ” this has to be the quickest and easiest answer to how a diffuser works. Looking forward to the rest of this series
This great can really seeing it catch on for newer fans
I was having a discussion about this a friend following the reveals if this season's cars, and I was having a hell of a time explaining this concept to this friend over text. This video made that a lot easier. Thank you!
I would hyperlink these to vids later in the race season when viewership might be higher and their relevance may be borne out again. This has expanded my understanding to include necessity and balance not just optimization. Consider a playlist. This is something you do very well although the 2 min edit-format may force you to cut to right to the chase. Offering details even spelling is helpful, for follow up Diffusion is the movement of a substance from an area of high concentration to an area of low concentration
Bernoulli's principle
Mummy, the shouty man is teaching me great things. :)
Haha
Wow Wow Wow... Great and simple explanation in 2min..👌👌
Was timing it for 2 minutes. Well done Marc! Does add a next question for me: #2mintech what is the purpose/effect of rake?
Gorkink, the same question popped up in my head right away! Trying to figure out what the pro’s and con’s might be. Red Bull has been very succesfull with the concept. They may be the kings of downforce! But is it due to the lack of engine power? “Waiting for the next episode of 2MinTech”
Carl, exactly!
Isn't rake just creating a full length underbody diffuser?
@@cornishcactus I believe so
Great! Simple clean and direct! Thanks!
Great segment, I love it
This was incredible!
Just awesome. Honestly I was like, Marc is never going to pull it off in under 2 min. Lo and behold! Great job, #needmore2mintech
This is such a cool idea, 2 mins to learn something potentially complicated that you might not normally get chance to dig into and understand, brilliant!! :-)
Nailed it Marc!👌💪👊 Being a short video I miss ur dogs being vocal in t background. 😢
Easy to understand,thanks
Can’t explain that any better myself well done mate these are going to be a good little segment
I like the 2 minute thing 👍
I enjoy the technical details, so maybe a 3 minute tech would be good for me and others like me. Yes, I'm an engineer. Thanks, and keep up the good work.
Great Video! Can't wait for more of them!
Really well put together video
Excellent explanation, thanks.
Now I can actually explain this concept to regular people. Thanks, Elvis!
You helped me today. Thanks
Nice one Marc........ 👌
Great explanation Marc you can finally catch your breathe :P , well done we love these videos :)
I can't believe you did it, you explained it very well in 2 minutes, you're amazing Marc!!
Nice one quick n simple
Venturi effect yay
Already loving 2mintech! Great idea, well presented.
Thank you Marc. I learned something on this sunday morning . Seeing how many questions you have received I believe you need to create an additional channel for these videos. #moredougdemuro 😎
That’s an excellent 2mins, never understood a diffuser before!
Great job , keep going .
thank you for this video
Fair play. That was awesome!
Make it 3 mins so you can take a breathe. Love your videos, keep up the great work.
Wow! Amazing! Super interesting but also super impressed that you managed to explain all that in just two minutes!!
Hi Marc,
Brilliant. Excellent concise explanation. Looking forward to seeing more!
Paul
NowI know what those big diffusers on Formula E cars do..thumbs up
Brilliant!
This is a great idea Marc 👍🏻👍🏻
wooooow!! love it!!! this 2mintech will be awesome. great start!
love these quick F1 tech features explanation...... gr8!!!
This was great, thanks Mark!
Simple, but explains it! Love your vids
good video explaining complicated process quickly and simply, keep doing these : )
Very good clear explaination!
perfect explanation
Nicely done sir. Good work.
Short sharp and very informative!
Brilliant Marc, thanks! Please keep this going on different topics💪
Awesome job an in-depth info. Thanks
Awesome!
#2MinTech is a brilliant idea. Well done Marc. Love the channel. Looking forward to next week.
This series is just amazing. Can't wait for more
Oh yeah! That #2mintech works buddy! Good job. Keep ‘em coming 😃
This is going to be a great series. Thanks Marc.
Well done Marc nice job!
Brilliantly explained Marc, keeping it simple #kuddos #2mintech
Great new series :) just bought your book, can't wait to read it!
#2mintech Suspension setup, dry vs wet. In the old days (70's,/80's) you could visibly see what teams did to adjust their car for different conditions. I remember seeing a Williams set up for wet qualifying with wide front track and a lot of toe out, just like we did in karting back in the day. Maybe that indicated they were struggling with the conditions that day but you don't see much of that anymore. Have the sophisticated diffs and electronics reduced the need for this sort of thing. I know 2 minutes to explain race car suspension tech is tough but I know you like a challenge!
Brilliant as usual👍
Great video, thanks mate
I like this feature! Marc on speed lol
Very good Video more of this.
Wow! And breathe now. I was actually nervous during the video, wondering whether you were going to finish in time. And you just made it, well done! Love these short explanations but you're going to have to talk a hell of a lot quicker still IMHO to do some of the suggestions for #2mintech I've seen....:-D
Very good explanation, very simple, but a bit too quick, I know that that the point, we would love to have may be a minute or two more? :)
And sky sports probably will be eating its words. Best of luck buddy. Love it.
Great explanation!
That was a simple and effective explanation Mark. Thanks for that. My question for #2mintech What is the purpose of razor like slits on barge boards, shark fins and other surfaces?
Neat.. Like it..
Love it
Now for next 2 mins please explain whats double duffuser and y brawn 01 was so successful?
Careful marc..Autosport will be nicking your ideas...great stuff!
awesome, keep them coming! #2mintech how does a wheelnut work?
I thought it was going to be a stupid idea considering your tendency to keep on droning (not complaining about that too; i love it). But boy i am glad i was wrong. I would love to know how
1. Airbox works
#2mintech
@Marc Priestley.... Well done, you need a few more colors of marker to it make more visually appealing.
Nice explanation. Can you add details of Brawn Double Defuser and how that improved the aero even more?
#2MinTech Hi Marc, great idea for the 2min Tech series! No idea how you managed it lol but great work! Could you do a section on the f1 clutch? and how different it is from what we know in regular road cars. Thanks mate
Great stuff! Really liked it.
#2mintech Q: Explain gurney flap
I watched like 50 videos on the diffusor principle now. And actually yours makes a lot of sense with the diffusor argumentation from the drag perspecitve as main argument! (Many other find dozens of wierd arguments, which all seem wrong to me). But I also find some aspects not quite clear.
First, Bernoulli's principle is valid along streamlines. It is more or less the conservation of energy along streamlines. So if a set of streamlins get accelerated this must be compensated by a reduction in potential energy (lower pressure) and vise versa. I don't see a logical argument, why the flow beneath the car must be faster than above the car, no matter how small the channel is. I could argue: a small channel probably has a larger resistance for the flow to be overcome and as we are more or less in the incompressible region of fluid dynamics (Ma
Hi Mark. Great Video. Can we get straight to the ignition technology that the teams are using these days in the ICE??
Bravo bravo
Great work @f1elvis! No pressure on that 2 mins ... excuse the pun ;) one more quick query on this for #2mintech how did this work in with the Brawn "double defuser" that helped them clean up in 09?
Here's a challenge. In 2 mins explain why diffusers reduce drag but not turbulence.
And, maybe the 2 wakes, the high and wide wake and the low wake.
#2MinTech How are teams dealing with the aerodynamic disturbance caused by the halo? How disruptive is it? And how come it isn't having a massive effect on performance even though it looks like it creates a hell lot of disturbance.
@Marc Priestley you make a mistake. The airspeed doesn't go faster ad the bottom as there is no defuser, than you have just a wing and the car goes up in the air.
The defuser is there to create a vacuum behind the car that sucks the air from under the car to speed the air up under it.
Good job! I expected you to accorate your speaking, once you neared the 2 minute mark!
Hi Marc
In 2 mins Can you tell us the advantages semi auto transmission has over manual , I feel this is the key to better RACING if we turn back to manual
rake!!!
Thanks for answering my question Marc and glad to hear I inspired you 🙌 I have another for you. Do you know why some of the teams are not using a large fin on the engine cover? (Alfa, Red Bull, McLaren) #askelvis
Hey Marc! - the change in gloss and matt varnish on the Red Bull car made me think of surface coating. I know there are experiments with aircraft using "sharkskin" type coating to reduce drag - du you know if this is also used in F1, and if not, why not? @
Marc, without the diffuser does the downforce still maintain at the rear due to the enlongated length of the area the low pressure moves through or is that a red herring. Or can it be traded off against the turbulent air?
Aerodynamics isn’t a strong point for me.
Great new content avenue with #2mintech
Can you do a 2 minute tech on the double diffuser like the one on the brawn GP cars? Still don't quite understand how it works
How exactly does the diffuser pull air from underneath the car? I understand one of the functions of the diffuser is to equalize the pressure below and above the car to reduce drag. However how the diffuser pulls air still confuses me. When the air hits the diffuser, the pressure increases, and I know pressure naturally goes from high to low. So how does the high pressure in the diffuser void pull the low pressure from underneath the car? Fluids was never my strongest subject in school haha.
The air is fastest at the entry to the expansion chamber, so by squeezing it through the narrow gap just before it expands, therefore accelerating it, the acceleration draws more airflow through behind it.
Super super vid
#2mintech ok marc so what was special about the double diffuser?
Geoff, very good question!
#2mintech I know this isnt a car/team question, but a racetrack question... why is the start line different to the finishing timing beacon ?
