F1 vs road car braking distance

[rvind92g]

I can even stop faster in my Smart Forfour. By hitting a tree.

[nikhiltcr1994]

that aint an M3!!!!!!! :P

[tiasboi3able]

bla bla bla who gives a shit

[CarleeSWE]

That is not an M3!

[gtino195]

thats not an M3, M3 has the air vent on each side, thats just a normal 3-series

[Nanospark5]

The Formula car is obviously going to stop quicker because it's a lighter car.

[tractorboydavidbrown]

did he say wanker at 0.14????

[skaterkid901]

As an M3 driver I suddenly feel very worried about my brakes now.

[Da2faan]

32 metres, is that all  :- (

[jnm98f]

The F1 car locked up the brakes.  He would have stopped quicker if he hadn't.

[Spoksy]

I can just feel the gforce, that god awful feeling that your insides will pop out of your chest

[gitrdonedavid]

Question how much more weight does the M3 have over the F1?

[manneredrock]

@gitrdonedavid F1 car weighs 600 kg, whereas M3 weighs 1300 kg

[neoc03]

@manneredrock - an F1 car at full speed weight almost 8000 pounds because of the downforce it generates

[manneredrock]

@neoc03 but as it loses speed, the weigh disappears

[ImTheSecretSquare]

@neoc03 Well, really what's important here is the mass, not the "weight" of a car based on downforce. The F1 has half as much mass as the M3 regardless of how fast it's going, so it has half as much momentum (mass * velocity) at the same speed, and momentum is what the brakes need to overcome.

[Master1906]

@ImTheSecretSquare No it isn't. It is the kinetic energy not the momentum

[TheGyldenlove]

@Master1906 No, it is the momentum, if you have twice the momentum you need twice the braking force to stop in the same amount of time (and since they are going the same speed, same time means same distance)

[Master1906]

@TheGyldenlove You are judging your theory based only on what you see on screen. Please don't argue with me. I am studying undergrad physics. I think I know. momentum is only useful when determing the relationship between 2 colliding objects and how one will impart some of it's momentum to the other. It is called the conservation of momentum. It has no relationship with the kinetic energy required to stop the vehicle in 'Joules' and is determined by many factors like normal reaction force etc.

[Master1906]

@TheGyldenlove I could write you an essay about this. Yes, the car stops twice the distance. That has no meaning without. You said 'Braking force'. Why would you say twice the braking force when the bmw clearly weighs 2x as much maybe more. Even with 4x as much braking force, you haven't thought about friction, reaction time etc... in short, do not come to a conclusion without thinking through the issue clearly taking into account all the factors and a little bit of intelligence will help.

[HiWd2]

@esukem genius*

[harrymilzy]

press 2 and he sais fucking formula! LOL

[devilselbow]

lmao and that's on the grooved tires. Imagine with slicks.

[district37nl]

holy shit gforces

[pvtdangles]

@esukem i did the calcs in 5 secs in my head when i was drunk dufus. and the last time i studied physics was when i was 14 .. why dont you take the calcs further genius and map the exact difference for a hypothetical non-downforce supercar with normal road car tires with a friction max of 1g stopping from 300kph compared with a 2010 spec red-bull rb6 with recorded max braking neg. acceleration starting at 6.5g's at 300kph ?

[bidefordrfc]

pfttt, thats nothing I once had a friend that went from 90mph to 0 instantaneously.....

mind you he did have help from a tree.. and wasn't around afterwards to comment on it....

[pvtdangles]

The difference when braking from 200mph would be even greater , f1 stopping force is proportional to downforce and downforce squares with speed. So there is 125% more braking force or thereabouts from 200mph for only 60% more speed

[madjh8]

Well, road car not exactly, my car will brake in more than100m of distance , tha M3 have very good brakes.

[BrotherYounis]

wow i was excited about getting my driving license soon until i watched this video, im a man f1 fan and i doubt that i will be able to put my f1 skills to use on public roads unless someone can happily donate me an f1 car :[)

[rottepung666]

they should have done from 186mph to zero then ya would really got your eyes open

[cvz1999]

its not m3, ok!!!

[pmlopmlop]

Wanna see the difference between a Pagani Zonda Cinque and a F-1 car.

Wasn't the pagani the fastest braking road car?

[Lemon0Tart]

@pmlopmlop yes bit it still wouldnt out break an f1.

[pmlopmlop]

@Lemon0Tart

I think it'll be rather close.

[CainG88]

Pointless test, the non F1 car is an M3, a £50k sports car, out of price range of probably 90% of the population. It has massive brakes. Why didn't they use a normal hatchback with front disc and rear drum brakes? Like a Punto or a Ford Cmax or something. A car most of us will actually be buying.

[jctevere]

@CainG88 Because everyone knows the Punto or Cmax will get destroyed and do terribly. M3 is a car that everyone renowns for its performance and handling. So pitting it against an F1 car shows how good F1 cars brake. If you put it against a cheap P.O.S. you will have skeptics saying the M3 or some other high end sports car would do better. You can imagine the Punto would do MUCH worse. You already have someone saying a Pagani might do better... lol

[robbie1490]

@CainG88 It's not a pointless test. That car is the same year as my bmw 330ci and its very very affordable, the m3 is about 3k more than what i paid. Plus i'm far from being rich.

[braceyoself777]

crazy how much distance 2 seconds are in that difference of time.

[Brylerce]

BMW M3 is my dads car

[toonarmy4ever1021]

god them brakes are good

[janssen70]

its looks like 120km/h

[cjwalsh7]

you couldn't stop that fast if you hit a wall!

[nazymann]

wasent even a m3-.-

[PATTYZ102]

@nazymann ya thats true 

[superhornet59]

So.. to improve road safety.. we should all drive.. F1 cars?

[Slipvayne21]

@superhornet59 lol, yep, i vote for you.

[machvelocy]

@superhornet59 count me in, lol

[nowheelspin]

@superhornet59 awsm idea!!!

[lifeisgood070]

.... lol now compare that to my truck lol... Drum brakes ftw.

[shumey7]

It takes it 2 seconds to get from 120-0. That's absurd! Anyone who doubts F1 as being the fastest and quickest is either ignorant or blind.

[Squawkerd]

@shumey7

Generally ignorant or proud, people don't understand downforce.

[shumey7]

@Squawkerd You don't have to understand down-force to appreciate how lightening-fast these things are. People who have ridden in a two-seated F1 car have said that the most impressive part of these cars is not the top speed. It's the breaking into corners and then acceleration out of them that blows people away.

[HerrenbachStyle]

i want a f1 to drive with it to work if i have only 5 minutes remaining xDD

[SuperRockstar206]

Vtec kicked in for f1

[scginda803]

in traffic. "Oh shit, woman in front of me on the phone just dropped her coffee, BRAKE."

"Geico squirrel in the middle of the road, BRAKE."

"Gotta get home b4 the game start, RED LIGHT CAMERA, BRAKE."

[2oldnot2]

That is why F1 drivers have to wear helmets - to prevent their eyes falling out...

[ASDFortuna]

Or maybe it would be safer if cars came standard with f1 tires and brakes

[VEVeight]

@ASDFortuna You would also have to shave another 400kgs off the car as well as creating extra downforce. Its not just the tyres and brakes.

PS If you were just being sarcastic, I'll slap myself now :-)

[kallo182]

Only for Imagine,

A Porsche 911 stays from 100Kmh (60mph) to 0 in 32 Meters.

A DTM Car stays from 100Kmh (60mph) to 0 in 18 Meters.

[bark1986]

all i can say right now is " sacrebleu " lol

[a10fjet]

I would drive an F1 car but where do i put my grocery bags?

[joyfulvulture]

lol...

[rossesc]

Mabye it would be safer if everyone drove f1 cars???

[tkelly27]

@rossesc

If the tires don't get hot enough they will not stop nearly as well. I imagine if you could keep the engine running at 40mph long enough to do the test, it wouldn't be all that impressive.

[davetupps]

That's not a M3 in any form. It's a M-sport E-46 coupe, More than likely a 330ci. The M3 distance and time would be shorter again. You can tell by the Bumper and the wing mirrors, Alloys are different too those are the MV2 spoke alloys (standard from 2002 onwards wth M-sport Trim)

[stoopefy]

flat spot, sorry I mean pointless

[LinkinPark9EVER]

F1 brakes for everybody in the world please :)

[dalilrafi]

@LinkinPark9EVER If you pay^^

[christofer128]

@LinkinPark9EVER or a 500 kg diet :)

[paulio2293]

and that isnt a shit car either.. imagine a shit car vs f1 car

[kfaslf]

the F1 stopped right away

[alexkvaskov]

wow

[kevincolvin]

My car can't even get up to 120mph =[

[Rocket432101]

@kevincolvin XDDDDDDDD

[kevincolvin]

@kevincolvin omg, i REMEMBER posting this!

[darijopotter]

@kevincolvin My car can't even get up to 120kmph

[magnum9987]

I think what he is saying in french is "I Surrender I Surrender"

[Claymore2408]

@magnum9987 LOL!

[TheGel73]

They should have done this top speed to 0, you should then check out the distance, it would have been phenomenal

[bigcomputer]

WOW!!

[MrJamDiaz]

FAKE !!!

[ScarTissue1990]

36m!! That's insane, that's a stopping distance for my golf at about 33-40mph!

[checkfoldcallraise]

thats gotta be painful on the neck. i think they wear hans device anyway.

[Stitch216]

Oh it is. HANS is designed to prevent basilar skull fractures though; it offers no assistance when dealing with the comparatively small braking G-forces in an F1 car (they max out at around 4.5G's of braking force). Skull fractures tend to occur at slightly higher G numbers/changes of momentum.

[magnum9987]

@Stitch216 You should see a TOp Fuel drag racing brake. They can go from 300mph-0 in so short a time that they generate 6 gs and can pop your eyeballs out of your skull. A Dude had to retire because he did that

[adrenalineboyzryan]

@magnum9987 top fuel cars also use parachutes, and the braking zone of a drag strip is uphill. Not a very fair comparison.

[lifeisgood070]

aw man... & that's a bmw M3.... I dare you to put up my car... you'd need a new track. it takes my toyota avalon over 450ft to do this.... lmao. I hate my car so much anyways.

[matheusgvb]

yes sander6san this time of 4s05 to do 120mph-0 (192 km/h-0) for a stock M3 is not believable... how can a M3 stop at 192 km/h faster than a Zonda Cinque, wich one does 200 km/h-0 in 4s40 (search on google to confirm) and is about 300 kg lighter, and has much more powerful brakes, etc etc?? so strange

[xcroatiaboyx]

thats a BMW M3 CSL :)

[sander6san]

Impressive from the M3. Given that a stock M3 62-0 is around 36m to 37m and additional 32 meters for 120-0 is not believable. Surely must have race brakes, upgrades, etc??

[DarkRoseProductions]

They should have had the M3 running behind the f1 car, see who stops first then.

[wilatemodel]

LMAO!!!!

[thytum]

man its not to compare, how heavy is the car? and the f1 ?? the most light witll stop more easy its clear.

[Harber3]

thats the point ... showing the difference

[ManOfMeans]

Tadi tyuah tyuah tadi tadi

lol - german

[inurkiewicz]

Really wouldn't like to be in the skin of that F1 driver, that must be fucking painful.

[chilby00]

@inurkiewicz are you kiddin..i'd sell my kids to be that driver

[Slashbag69]

@inurkiewicz Yeah, your eyeballs would be smooshed against the visor :P

[yutubehero]

i wanna see this demonstration with my buick instead of the bmw- 4 wheel drums, no power assist xD

[tzurka]

lol the F1 weights about 600 kg and BMW is about 1500kg , its normal difference for these machines.

[ed200007]

Where can I get those brakes

[racefactory900]

its where you can get the fucking tyres, not the brakes dude

[michaelthepsycho]

It's a combination of everything. Light-weight chassis, rotors, pads, calipers, aerodynamics and yes, tires.

[racefactory900]

obviously, yes. no need to be a know it all. just pointing out to the guy that tyres play a far more important part in braking distance than the brakes themselves on a road car.

[michaelthepsycho]

The way you said it, I had to do it :D Obviously, I understand you know your shit...

[racefactory900]

那没问题！呵呵。

[golfinguy55555]

fuck well no shit but of course the f1 would brake far less distance than a regular car

[thetourle]

The only way you'll slow down sooner than that is to hit a brick wall

[DORUKOZKAN]

haaha lets puts f1 brakes on all our cars so we never have too be afriad that we dont stop on time haaaha

[Dupster1234]

fark.....u see f1's sliding around like crazy sometimes this is awesome stopping powa!!!1

[damo1128]

lol i thought u said fake, i was about to be like wtf

[compdude47]

That's stopping on a dime!

[burritomaker69]

but thats not a m3

[Melo15xSTAT1]

DAMN!

[C20rules]

That's awesome!

I like how the M3 just keeps going long time after the F1 already have stopped. - but is the speed really 120 mph (193 km/h)?

The BMW M3 stops in 4,05 secs - that's an average deceleration of 13,3 m/s² (1,35 G)

 - that seems very fast for that car

If the speed is 160 km/h (99 mph) - wich is a common speed used for brake and acceleration tests.

The average deceleration of the M3 will be 11 m/s² (1,12 G) and for the F1 21 m/s² (2,14 G) - seems more correct.

[safeting123]

alright showoff

[racefactory900]

that's right man, 1.3g is too high for a road car, either the speed is wrong or it must have slick tyres which might pull something close to 1.35g.

I'd be surprised if that car, road legal would get more than 1.1g. 1g for the tyres coefficient friction and .1 for aerodynamic drag!

nice work! I think it is 160kmh too...

[champiforest]

great

[melok2]

good braking man hehe

[Poutross]

Impressive

[shckar]

ow!!!

[yoman2002]

amazing!!!!!!!
