Slipstream : Driving very close to the car in front of you What does it do? Reduces downforce, sends the wind over your car, helping you go faster, but also reduces stability around the corners, where this wind turns into dirty wind. On straights : Less downforce required for more speed On corners : More downforce required for more stability

[@Frank-jg4tq]

Thank you 🙏🙏

[@tzalwelweetwel]

This was so much better explained

[@user-hv7jv5zl3y]

^ agreed

[@pankaj3711]

Ll

[@dcrey7]

killed it

[@timzy4395]

Now I can see why Vettel keeps shouting "BLUE FLAG"

[@lwmartinez]

HAHA

[@timoficatalin3445]

well he has a point

[@StarryNightGazing]

Not sure that showing a McLaren while saying "allows for higher top speed" is a genius idea

[@spongeproskater]

Stargazer ,Alonso "it's a joke"

[@loek3577]

Nowadays it kinda is

[@cw0058]

🤣🤣🤣🤣🤣🤣🤣🤣🤣👍👍👍👍

[@vs-id9yr]

This didn’t age well

[@abramo7700]

can someone explain?

[@aslamnurfikri7640]

Next one should be tyres. How they work, how they are manufactured, and how they are treated during race weekend

[@robinvertuinsophangconstru7488]

Treat them with respect

[@jamieplaysagamie]

For the next one do how the halo will affect the performance of the cars

[@kingieav]

probably wont do much apart from a little extra weight

[@AtotehZ]

+Kingie AV That's not true. We already knows that it disturbs the air flow and air intake above the head of the driver. I don't think we'll see anything definitive before the teams give their own assessments however.

[@kingieav]

oh yeah myb forgot about that

[@mpaco9112]

The halo also makes the center of gravity slighty higher.

[@Random63R400]

That's something we can't answer for the moment the Teams must give their answers To your question

[@kabelosehanka8302]

Dude, thank you for this. These two things really confused me, but you explained it so well

[@chainbear]

Hmmmmmm

[@kienpham4382]

Hi Chain Bear

[@user-cg7tj7cu4m]

Get verified my dude

[@souravtambe5743]

Woo not yet verified ☹️

[@colinbriggs8998]

Thought of chain hair when I saw this video

[@lore-lv2yo]

Richer

[@sebastianespejoloyaga7603]

Suggestion: Downforce differences with the Halo.

[@LightSightTCR]

Suggestion: minigun on Halo

[@sebastianespejoloyaga7603]

Eerik L According to Mercedes' video "F1 explains: The Halo" at 1:29 it says: "This thing is quite bad aerodynamically".

[@jimutjayadev]

Eerik L anything around which air passes on the car affects its aerodynamics

[@jimutjayadev]

Eerik L lets see what aerodynamic appendages the teams come up with to better utilise the halo

[@jOoomOooo]

WTF DOES THAT MEAN ITS HARDLY DOING ANYTHING TO THE FLOW AT ALL I honestly doubt it would effect the downforce a lot but if anything it would help the air over the cockpit

[@Malwontae]

Matt: Top Speed... McHonda on screen... Thinking

[@tees6675]

very informative video WTF1. Well done!!!!

[@vettelloab705]

Great video keep this series going

[@Wingbar]

Guys I really really love your videos. I always click of the thing I’m doing to watch your vids! Keep going 💫

[@kianolner3818]

The goods and bads of refuelling

[@10babiscar]

Good: Keeps the engine running Bad: Makes your hands smell

[@benabdi]

Please explain safety car restarts to new comers, and what adventage they gives in terms of pitstop and so on

[@lucasvdh1938]

Ben Abdi you should check out chainbearF1 he has extremely detailed and informative videos about f1 rules and aspects!!!!!

[@benabdi]

Loescaas i said to the newcomers man. I've been following f1 since very young man. Newcomers don't know shit yet won't care about the truth. Have you seen current Interlagos curves? Curves are meant to be attacked, not watched behind a line

[@YannickMX2]

For the next one I'd like to know how much force there is on the steering wheel, torque levels generated by the wheel and comparision to a normal road car. Simracing steering wheel are becoming a lot stronger lately, but does stronger always mean that it is closer to the real thing?

[@AdrenaLukeYT]

All toasters toast toast

[@bjr2966]

I was actually thinking about what the difference was and 2 days later, this video is born.

[@superstar5042]

There is no difference between dirty air and splitstream. Its the same effect called by different words. Less air helps you on straight line with more max speed, but makes you slower in corners becouse you have less downforce.

[@billiejean6520]

I just love the work and effort that they put into F1 cars, for us fans to watch in enjoy

[@666CaptCarnage666]

Great vid man. I also recently got my "Bwoah" shirt I ordered from the store, love it.

[@ntst22]

You guys can try Undercutting, or getting Free pitstops under the safety car. Or even try explaining the new tire rules or Grid penalty system for 2018

[@armands3153]

Atleast i know, when Chain Bear F1 goes to another hiatus unexpectedly, I can count on you for simple explanation videos, though I'm more interested in more complicated mechanical things.

[@steveellis7916]

@WTF1 I would be interested in seeing a break down of a F1 tire, and the varying differences between the selections (wet, soft, extra soft, hard) etc

[@ollieoxley7382]

Love this series

[@garethbartlett3076]

Fantastic video really enjoyed this 👌👍

[@Matt231985uk]

Nice video! More like this please! Why not make a video on pit stops, race starts, crashes, strategy, tyres and more science!

[@AbhishekDantale]

Your best video till now. Keep it up

[@joelcontreras604]

Great post!

[@iamdanyc93]

Thanks for the insight; didn’t figure out there was a difference

[@githice]

Trying to understand this slipstream drama from Monza to Sochi.... I shall catch up somehow

[@silviomp]

Now that makes sense to me. Thank you! I get off the track every time I tailgate in curves at high speeds. Games are really realistic these days.

[@nicholascharles4399]

My suggestion is: The different types of track surfaces and how they impact tyre choice.

[@weatherfan1925]

Next, you should cover how a dry line forms.

[@GavinHitchens]

Do some detailed stuff about operating windows, could be for breaks and tyres or even about turbos and how the electric power torque fills to keep that operating window open

[@mazehew3946]

For the next one could you explain the difference between the nosecone shape most 2017 cars had, and the one that the toro rosso and mercedes had? (I know they have names, but I can't think of them, hope you understand what im asking) cheers!

[@wizsharif1357]

idk how i managed to make it here but this was the most interesting thing i’ve watched this week.

[@samratsaha6029]

Cool animations...keep this going

[@MrRay2364]

That's was awesome I didn't even know there was such a think as dirty air.Thanks man.

[@natjohno02]

Been waiting for this 😁😁😁

[@wafflesmartano]

Please explain how to use the safety car to make up a place/ save your lead and in general how to use it as a race strategy.

[@davidayona2037]

I just grabbed a great interest in the sport of F1and i want to understand a big more of it. Why do drivers start in the place they do at the beginning of the race? How the season works? And how are the champions decided?

[@strikeagario997]

Could you make a video about Ground effects for the next F101 episode?

[@gclarett]

Do a vid on G-forces and lateral loads on tires, body roll and drivers neck.

[@nigelswan1018]

Wow love that intro

[@AshwinDivakar007]

I finally understood dirty air. Thank You

[@quintenhendrickx8086]

Explain each tier and the pro’s and cons’s of each tier plz 😃

[@x_rod]

Glad that I can watch a video that isn’t on Buzzfeed levels from your channel.

[@emperorlelouch5696]

Wow, this all makes sense now. I was watching an anime and they mentioned this, so I was curious and now I understand. It's pretty cool.

[@rapid_tine_roddo1019]

Great vid but a question what do u think is the best and worst livery and u can do a top 10 list when all the liverys come out

[@armands3153]

Point Blank Well, all I definitely know that Haas won't be in the last place. :) Simple and not overdone that works very well.

[@klouczech]

Nice informative video. And low cooling in slipstream!

[@sambitparida4370]

This was literally the first question I had in my mind when I started watching f1

[@Ramraj07Manutd]

Best F1 channel on KZbin

[@jacklundy4344]

Suggestion: How much does wind affect the car?

[@johnchampion6926]

Ground Effects - Should they return to F1?

[@johnchampion6926]

Subi_fan I wouldn't agree fully with that, but definitely there has been some pretty dull races

[@vjollila96]

Yes and make wings simple kinda what indycar is doing for 2018

[@johnchampion6926]

Oh definitely, also it would be nice if they were brought inside the front wheels so they dont break off at Turn 1 every race

[@jakobkienast]

ground Effect takes place in present day Formula1 - it produces a quite big amount of Downforce of the car

[@johnchampion6926]

Technically, the cars at the moment don't have ground effects. Ground effects has been banned in F1 since the early 1980s. The cars do produce downforce underneath the car but it's a minimal amount as most downforce comes from the front and rear wings

[@Mike1-]

Great video thank you i was wondering how dirty air worked

[@rreichertnhs]

You guys should do a video explaining camber

[@acruzp]

This was a great opportunity to do a collaboration with a channel like Real Engineering, and you guys missed it.

[@maykues]

This guy sounds similar to the guy who gives me advice before a race in Gran Turismo Sport

[@SheetFiber]

Slipstreaming in straight is good, slipstreaming in corner you loose downforce.

[@satyaashokdowluri1129]

Can you explain the rules of f1, what all changes have to be made in the cars each session

[@johnvanoevelen2]

For the next oneyou should do Mechanical Grip 101

[@a.l.e.x8118]

explain what an undercut or overcut is basically the importance of strategy

[@f1visionary866]

Alexander Schlecker check out this channel, ‘Chain Bear F1’ they have lots of really short informative videos about all this stuff

[@Walker_41279]

What do I want in the next F101? Tyre degradation or Setup effects

[@ralph0x]

You should do the difference between understeer and oversteer

[@NGXII]

Does anyone know if there has been an effort by any team to optimize their aero package for running in dirty air?

[@evelozbert1851]

Next one are the tyres please Matty!

[@NANGSGARAGE]

Difference between undercut and uppercut and which one should Webber do to Vettel 😝

[@natteharry391]

NANGSTAGRAM TV You still in about that? Its almost 5 years ago

[@thatcarguy536]

How different tire compounds are made differently

[@zaccasey5932]

Do one on downforce

[@wetsocks4460]

To put it quickly going behind a car gives less air to push you back but it can sometimes make more air to push you back

[@jamesplaysgames9901]

I haven’t watched the video yet but it’s simple logic. While behind another car the affect of downforce is significantly reduced which is a benefit on the straights (higher top speed) but through corners you’ll lose time behind other cars because you need downforce to carry as much speed as possible through the corner.

[@SheetFiber]

Help me understand ground effect and the importance of diffusser

[@JosephGamer20]

I would like to see and know how “telemetry and sensors’’ work for a Formula 1 team I have have always wanted to know about that

[@ryanford5387]

Another way dirty air works is the hot exhaust fumes from the car ahead. Hot air is less dense than cold air meaning there is a less 'surface' for the wings and so on the 'push' on.

[@wingerplayz420]

Do on how halo will affect the 2018 cars compared to 2016 or 17 cars

[@kabirf1670]

If so, then why is DRS zone on straights and not while cornering? DRS is much needed in corners than straights, as on straights the car behind is getting the advantage even without DRS. Please explain

[@lanceward4665]

Drs reduces drags AND downforce, as in if you use drs in corners, you’ll be even slower than not using it

[@DanielZellmer]

Next Question: How many tasks have a driver to do since one lap? how many different settings for the wings, the gears, the pedals, besides the driving (spinning the wheel and look to the opponents), to drive as fast as possible?

[@_VHwK]

basically you could have just said, its the same thing, its only called dirty air in corners and slipstream on straights, because you use different traits of the air blowing against depending on where you are, and what you are doing

[@samthompson2130]

RIP xMattyg1, I miss your F1 career commentarys 😭

[@uyhu24]

ITS RACETIME ITS THE CHINEEZE GRON PROC

[@thatsidewaysdud7623]

MAGYAR NAGYDÌJ

[@jw8599]

perseus 'There's a prick on pole and a prick in 8th ... On prick tires'

[@Bazzookie]

F1 needs to make it so more downforce comes from the underbody like what they’ve done in Indycar to improve the racing. With the ridiculous budgets of F1 they probably could produce a lot of downforce underneath the car rather than rely on a front and rear wing (for the most part).

[@checo8446]

I think you could tell us how downforce actuall works

[@looktothefuture84]

You've been speaking to Alex, haven't you? He's bascially a racing driver you know.

[@boney_ak]

that base intro

[@shashidharshetty7457]

How about explaining Tyre temperatures

[@irfanalfiansyah4520]

Explain mgu k,h, ice, etc please

[@imranpatel4612]

Explain team differences and why some cars are so much faster. How much is down to the driver skill ?

[@ruanjrdn]

Make a video on the oil being put directly into the combustion chamber.

[@afcreative22]

I'm the 101st like on an F101 video. I find that pretty funny.

[@floherp]

Cool name for the series.

[@Luka-hc4de]

How does ERS work?

[@iuvdisuhb-ld3ou]

I like how he used his channel name on the cars

[@hlo4299]

what tyres to use on what track

[@Random63R400]

H LO It depends mostly on the loads u get from the corners after It's the track temperature and the track itself (is it a smooth track or a more bumpy etc)

[@ChandlerSeita]

you should pair up with ChainBearF1, he does the kinds of videos and i don’t want you to take over these types of videos so it would get hopi. more exposure and keep you guys on equal ground in the informative videos

[@sgxbot]

In short and not so complicated: Dirty air and slipstream are the same. Reduction of downforce/drag due to another car clearing the air in front of you allready which results in higher speeds on straights due to less drag/downforce and and lower speeds in corners due to missing drag/downforce.

[@sgxbot]

Drag and downforce are the same just called differently depending on the situation and if its good for the car in the situation or if its bad. Same with slipstream and dirty air. Its the same thing. Its simply less air pushing the car down and back which has different results depending on what the car is doing

[@superstar5042]

Yea. Explanation in video is really poor

[@snipasean7069]

I used to think dirty air was just the exhaust fumes when I was little

[@qsr6838]

Your not wrong that also make dirty air

[@imp4ktth]

tldr getting behind your opponent in straight line is good, but in corner is bad

[@latostime9849]

Not sure if this video still has valid argument cause i dont see this thing happen in actual F1 race in nowadays. Every driver are racing closely behind each other in straight line and even when in corner.

[@hoelefouk]

Just letting you guys know if you, WTF1, don't get this often, you guys are amazing.

[@abhishekbanerjee2679]

front wing components and their advantages ??

[@pikestance4219]

So the term "Dirty Air" is mostly a misnomer. Outside of the air being heated, it is really more of a lack of airflow than heated air. So low downforce tracks (faster corners) would actually promote more passing (racing) than high downforce tracks. It makes you wonder why here aren't more tracks with mostly high and medium corners. How different would racing be if it ran in late fall to early spring, rather the late spring to mid autumn.

[@Thrashmetalkicksass]

That's quite clear. So basically slipstream works well on the straights because it's a "predictable" environment in terms of wind but not in the corners, 'cause the wind goes all over the place, is that right? But there's one thing I've never understood: why is increased downforce always an advantage? Doesn't downforce create friction with the ground by making the car "stick" to it? Shouldn't this slow the car down? Thanks to those who will answer, if anyone will.

[@frdrcojerry]

0:36 any video of this ?
