- Could an F1 car drive upside down?
The whole world seems to think so, and in theory, they are correct. With some simple calculations, you can see that they generate their own weight in downforce at 120mph, and much more when going at speeds close to 200 mph.
Now, this wouldn’t be the first time a car’s been driven upside down on a ceiling, but it’s never been for more than a split second.
But F1 cars, with their ridiculous levels of downforce, could (in theory) be driven upside down indefinitely.
Well, today we are going to dive into the physics behind it. All to see if it’s actually possible, and if it is, then why hasn’t someone done it already?

How about doing it around the Hadron Collider tunnel? Sure you'd have to rip out the $4.75billion particle accelerator, but it's a small price to pay for awesome!!!

Let‘s be honest, if this was possible while spending non-insane amounts of money, Red Bull would have already done it as a marketing ploy
I think it’s more of a safety issue than a money issue. But Red Bull funded that space jump with Felix Baumgartner and that was definitely more dangerous & more expensive than driving a car upside down, so I guess anything is possible.
I think is little bit of both, money and driver safety, because they probably would need an specific place to do this and It would cost a ton of money, and second and most important the driver safety would be compromised at every time you look at it and extraction and everything related is dangerous due to the nature of the challenge

Monaco metro tunnel grand prix tune in next week from the normal monaco gp
Appropriately designed internal combustion engines have been able to run upside down in many applications. Clearly it's only an issue if you stick to using an existing F1 engine without modification. A suitably designed corkscrew ramp at either end of the tunnel could allow the car to remain on a flat surface with 4 wheels on the track at all times. I have no doubt that this stunt can be done with enough care and planning. Modern remote driving technology would enable it to be done without risking a driver's life.
Same thing I commented although more thorough. I agree
rotary engine should work fine regardless of position so take engine from old mazda 787b, add turbo and you will have more than enough horse power without adding much weight, you just need two fuel pumps in the tank, one on top second on bottom
@@czaja995 Don't think you would need to make any changes to the f1 engines nowadays, I would imagine they would be efficient enough even upside down, I could be wrong though
@@czaja995 Rotary engines cannot produce enough power... It's much less expensive to use an electric motor, at this point is better.

Exciting and dangerous
@@MGuairense

It's definitely possible, no doubt, especially because the car that gets this challenge will even have more downforce wings to make sure it doesn't fail.
It sounds possible. Imagine if they just slap two fans at the back to create downforce... (assuming the fans don't add a lot of weight)
@@decay2__ then they would have to make a brand new car, because the fans need skirts and other mods to work

If we would focus just on the "driving upside down" part and ignored the "getting there" part. It could be fairly easy, the engine wouldn’t have to deal with the change in orientation, if it would be installed upside down. So the only part that you would need to tackle would be getting to the sufficient speed, to stay on the ceiling. I imagine it can be dealt with in number of ways, maybe some moving construction that would support the car from underneath until it would reach the required speed or some sort of attachment to a rail on the ceiling that would hold the car. Although it's a question if an "F1 car" with engine mounted upside down, meaning it's inability to function the right way up, is still an F1 car
They can make engines for acrobatic planes that work upsidedown for decades now, I don't think it's impossible for an advanced F1 team to design something similar.
or just use an electric motor.
while it wouldn't "technically" be an f1 car it would be close enough for most people to be satisfied with the result and you dont have to worry about oil starvation. especially if the weight of the car with the batteries and motor(s) is equivalent to a ICE f1 car.
Why would you ignore the "gettin there" part though, that aspect is impossible to avoid...
@@sansxerife2008 You could theoretically pull it off in a vertical looped track: throughout a smooth enough loop you get a constant flow of air and therefore have enough downforce when driving upside-down.
Expensive af though.
Just a suggestion, you need the car to reach a certain speed in order to generate enough downforce to stay upside down. Instead of that, create a platform that can hold a fully functional F1 car and have clamps hold it to the platform and then put it into a wind tunnel generating as much wind as needed and then simply unclamp the car and see if the aerodynamics holds the car in place. Would that be better?
yeah sure thatd be easier but then you’re not driving a car on the ceiling, you’re just testing if a car has enough force to stay on the ceiling
A lot of the "facts" presented about how aircraft can fly upside down are, sadly, incorrect. My aerobatic aircraft can fly continuously upside down for at least 30 minutes, limited only by the design of the fuel supply system. There is a limitation of 30 seconds for "knife edge" flight due to oil starvation, but there is no system on the prop to "unload" the engine when the oil supply fails - in fact there is a system to INCREASE load to reduce engine RPM.
As for the pilot, 30 seconds inverted is plenty!
@Combat Mania I wish! Nope, just a hobby pilot flying the sort of plane you could find at some local flying clubs.
@Combat Mania I was 29 when I had my first flight. I was cash limited, so I was 32 by the time I got my license. I bought a share in my aerobatic plane when I was 36.

*Ferrari has entered the chat*
Wankel engines be like "what?!"
LOL at the picture of the Haas cars and the caption "Even these guys!" when discussing the 185mph speed requirement and stating "Any car on the grid today can easily do this..."
Bottom line, if the engine could run and you had a helical entrance ramp to the track, yes it could. That's what people are really discussing, the amount of downforce they have relative to their weight (much more than 1g)
As for practicality, you could build speed before the ramp, and the inverted track only needs to be long enough for 5 seconds at 180mph.
A forumla E engine with 1/10th the battery (plenty for this example) would weigh much less and would free up even more power.
Lmao, “Even these guys.” Almost spat my coffee out. 🤣
Pretty good video, but the Lærdalstunnel is the longest tunnel intended for road traffic, not the longest tunnel overall
I feel it's a bit misleading to say that reducing drag is a key philosophy of Formula E to make the Race distance possible. For 2 Reasons: Firstly, the reduced downforce reduces dirty air and therfore makes overtaking easier and the races become more interesting to watch - also, the cars are designed to be sturdy so they can continue racing somewhat competitive after contact and even Braking off the fenders and front wing. Due to the fragile aerodynamic structures, this would be impossible in F1. And second: Formula-E Cars don't deplete their Batteries during a Race. The Capacity is limited by software and different for each race. They deliberately reduce the Battery capacity to make sure that energy management must be a part of every teams strategy. They might be reduced even more after every safety car or full course yellow because during these phases the cars use less power and wouldn't have to save energy for the rest of the race.
So in summary i'd say I'm convinced: if they wanted, they could have much more downforce and stickier tires and still make a full race distance on one of their street circuits. Even though it's obviously impossible to reach F1 levels of performance on GP-Tracks for F1 race distances.
I doubt it’s misleading, he also references the correlation between vehicle weight and need for aero on lighter cars. The formula e Is around 250kgs heavier than f1. So it’s need for aero is considerably less. I’m sure if the ability for speed and longevity where there… the dirty air and fragility would hardly be an issue if it meant the car would benefit from it. Given it’s so fat and slow no need for wings, just charging ports
@@riz3nfpv306 I disagree. More weight means more force pressing on the ground but also more inertia to overcome. All positive effect of weight will always be overcompensated by negative effects.
The entire rulebook is build around short, thrilling races: tight tracks, attack mode, and uniform, robust chassis. Even the qualifying is designed to handicap fast drivers. Having a lot of down force is directly opposing this concept as it gives following cars a massive disadvantage.
But mainly, I wanted to say: range has never been an issue for formula e gen2 cars. If it was they'd use bigger batteries or shorter races. They artificially limit the range on purpose to enforce interesting tactics. So it's clearly misleading to imply that the cars struggle with a race distance, when it's obviously on purpose.
It's not misleading. That information just isn't in the scope of this video, and going that far in depth would send the video way off topic. It's clear you're passionate about Formula E, but there's a time and place for everything. This video was not the time and place for a huge info dump about the structural integrity and aerodynamics of a Formula E car. You're getting tunnel vision (see what I did there) about a very small part of the video.
Again, not misleading. It's concise for the purposes of the video.
@@8thlvlMage I get that it's not strictly misleading in the scope of the video - one still gets the point - but considering the scope, the reasoning behind FE aerodynamics was unnecessary.
I called it misleading because It's spreading a false picture of Formula E. I wouldn't ask him to talk about it more, just to not say stuff like: 'they have low down force because they are electric and need to save energy'. Because that's not the actual reason.
Bumps and surface imperfections are another factor that is hard to account for
Well once the car has decent force to the ceiling, greater than the car's mass, it should work alright as long as it doesn't slow down.
This was much more intellectually valid than it had any right to be. Well done.
Just wait for RBR to do it one day.
Looking away from a theoretical tunnel, building an actual tunnel to pull this of would cost Red Bull more than an F1 season
@5:08, the air-fuel mixture in a Top Fuel engine is under such high compression it's actually in a solid, gelatinous state. TF engines operate on the verge of hydro-lock by design, I suppose. At high enough pressures, fluids freeze or solidify, as-if they were cold, regardless of the high temperature present.
I could totally see Scott trying this one!😉
How about an engine that dynamically adjusts its orientation according to a reference plane. I guess it would require a lot of R&D to reduce energy loss and weight increase due to the added mechanical complexity.
just mount it on a rotating bar with the enter of weight below that bar so that gravity would hold the engine upside down. not much RnD to built that. just make sure that it cant rotate by the crankshaft rotation.
@@patrikjansen7831 The word 'just' is doing a lot of work there
@@DjDolHaus86 you could test it whilst being stationary and maybe use a few actuators, not what i would consider as a lot of rnd
@@patrikjansen7831 You seem to be overlooking the minor issues of packaging (space in the engine housing) and torque (if the engine is floating, what's to stop it spinning itself rather than spinning the wheels under load?).
Or you could use a boxter engine. It has horizontal pistons
What an absolutely amazing video! Loved every minute of it. More of these please!!
great and fun video, my compliments!!! Quick tip, you would multiply by 10 the quantity of viewers if you used kph intead of mph, as the vast majority of people in the world use SI units
Something I don’t think you considered with that 185 MPH requirement is the traction required to deliver enough torque to overcome drag. Drag is also proportional to the square of the velocity. So even with the equivalent of the car’s weight pushing it’s to the roof, you might not be able to deliver enough torque to the roof without the wheels slipping. You might even need significantly more than 185MPH
*1:55* Did you actually watch the video? Or just comment?
@@SamBrickell The way I phrased it isn’t quite right. He makes the assumption that the a net force equivalent to the car’s weight would provide enough traction. It might actually require more than this, it might require less.
Yes I did watch it😂
What about 186MPH?
The McMurty Speirling could do it!
Also it could stop upside down, reverse a bit(to show off) then continue on driving upside down. :)
The car weighs ~1 ton and makes ~2 tons of down force at a stand still.
Challenge Extended! :)
This video got me fascinated with F1 and I went a few months watching F1 series and informational videos, all because this video sparked my curiosity
very nice video, can you make one where you discuss weight itself and how it changed in f1
I think you could quite easily (by comparison) do this in the real world if attempting with a scaled down model version of an F1 car that uses an electric engine, one that is still quite large, maybe even (and I'm just guessing) as big as half size. Because model cars in general have an insane power to weight ratio and accelerate incredibly fast too. It wouldn't be quite as cool without a driver but I think it would still be very impressive to see it done in this way in real life.
In other words, we need to increase development into true electric F1 cars
Fascinating as always. Great video, thank you. ✌️😎
Wow, I just found your channel and I want to watch every video. Great topic ideas!
One way you could do it is instead of the car moving forward have it stationary in a wind tunnel that can generate 185mph winds then rotate the car upside down, all problems solved and the driver doesn't get hurt if it all goes wrong.
Yup that though occurred to me as well during this video. Also, everyone is thinking "tunnel." Why not just build a suspended track on some salt flats somewhere. Would be much cheaper and safer.
@@nicklangner Right thinking! Maybe there is no need for the salt flats either. If the track will be suspended from the beginning and just gradually twist around it axis you don't even eliminate the initial elevation chance of "running up to the ceeling".
@@xhornik My salt flats idea was more about a space without obstacles, like land speed record attempts. But dang! You took @Danny Howard and my idea and smashed them together. I like it! Throw on a frame with small wheels like a wheelie bar on top of the car (a small one that doesn't negate too much downforce), build your inverted section of track so the wheels of the frame are only a few centimeters off the ground when the car is inverted, and you might find a driver crazy enough to try it.
I think you could solve the 3 wheel problem you mentioned at the end of the video by turning the twist to either side, think how Zandvoort banks heavily, same principles I imagine, allowing drivers to drive straighter lines. It would end up looking more like a corkscrew rather than a barrel roll.
Also the exit of the upside down part should be opposite to the entry to ensure that the car isn't relying on any of their velocity in the circular motion to keep them stuck to the ceiling. (not sure if you mentioned that or not but I think you considered it defintily)
10:58 Yes it loses down force from the aero but you forgot to account that during the flip it gains "down" force from centrifugal effect.
Bro. U did awesome job with ur explanatios.. all the best👌🏻
Just waiting for Red Bull to finally do this stunt as a stunt. They're pretty well known for doing ridiculous stuff with their cars.
I mean Zhou did it at Silverstone, so...
I've seen some other video where it's been suggested that special structure would have to be built for this - something like "semi-tunnel" or letter C in section... would be expensive but not as a proper tunnel... and wouldn't disturb airflow... also being open from one side it would be easy to watch whole experiment.
Good morning sir..its always nice to hear you explain you informations..content are well spend time putting it tougher ...you keep doing what you enjoy best..i have learned so much for your vedios ..you a great weekend
How about a version of an old Porsche CanAm car. I seem to recall that they generated several G's of downforce using lexan skirts to reduce air flow under the car, and a fan to suck air out from under the car, generating very significant downforce. They could probably support themselves on a ceiling while stationary.
is the downforce of a F1 car distributed evenly between front/rear weights? This could be a challenge as well if they aren't.
They can be tuned for equal distribution
@@sidharthcs2110 correct, actually is something like 48% front
Not too far off the center, and if the downforce exceeds the gravity by a significant margin it should be a problem
Love your videos man
Wow this is great. I've always heard f1 cars could drive upside-down but can't believe I never thought of the fact you'd need double the weight of downforce, not just equal.
Design an f1 engine that works upside down.
Accelerate the car up to the required speed using a catapult similar to an aircraft carrier
That’s a good theory, you could catapult it to the needed speed, make the transition, and then fire the motor
@@spencerb311 You could suspend the car upside-down and pulled tight to the ceiling with some form of harness, accellerate it with the catapult, and then release it to run on its own once it gets up to speed.
The claim is that the vehicle could drive on the ceiling, not up onto the ceiling.
Was oil starvation accounted for?
In BeamNG drive running an engine upside-down will cause it to burn oil, damaging the engine to the point of a loss of power/torque or engine failure. This would cause a loss of speed resulting in a loss of downforce which would result in the car falling off the upside down road
That depends on oil sump system
You may have heard of "dry sump" engines, and the usual "wet sump" engines
Dry sumps help against oil sloshing into the pistons. Aerobatic planes have dry sumps for this reason
Also, see 4:40
Watch full video first, comment second
Even the super-serious Scott Mansel mocks the Hass :D gutting but still, quality content ^^
Great video!
How did he arrive at 2 G for the “upforce” ? It only need enough force for the tire to have grip to move the car forward and for the car not leaving the ceiling when there is a bump.
Simple:
1 G is used *just* to negate gravity - leading to a net force at the Tyre of 0G, which if you factor into your traction equation, a value of 0 weight = no traction. So you need in excess of 1 G.
The next problem is the Torque of the engine at high RPMs, if you had say 1.1 G of downforce, then the moment you go inverted, the wheels would start to slip, which would be less than ideal.
So 2 G would give the same traction as when the cars pull away at the start, However, I think this is still a little optimistic, as it's really a around 60-70 mph that the Aero is producing enough force to really use all the engine power.
@@MajesticDemonLord so you think that if I accelerate a car to 180 mph and maintain my speed. If I lower the force of gravity, it will immediately start to slow down. I would have thought just enaugh G to create the friction to transmit the power necessary to maintain speed.
@@richardlehoux Not quite, you're maintaining a constant speed, but due to the Aero, you have a lot of Drag, suddenly you reduce traction by 50% - what happens?
The George/Bottas crash comes to mind, the rear tyres would spin - which would snap the rear and then all that lovely downforce goes away.
You would likely need a higher speed to make sure that the car had enough traction on the rear to not spin the tyres.
Nice video mate.
LMAO - 4:12 Love your humor there!! "Even these guys" 🤣
Thank you so much for the video! What if you twist the road instead of driving up to the top of the "tube like tunnel"?? Make it a like a roller-coaster!!
I say put the internal combustion engine on a rotating gimbal, so it stays right side up regardless of the cars rotation :d
What's being overlooked is the stability of the suction up against the ceiling. If the cars moves away from the ceiling the upforce will diminish...and unstable change.
Sounds like a job for the McMurtry Speirling, a fan car which generates on the order of double its weight in downforce at zero mph.
Look into the tunnels in chicago to store stormwater.
It’s called the tunnel and reservoir project aka tarp tunnels.
It was made by the sameacgine that dug the chunnel and theyre indeed as big as youd need.
Theyre empty in the winter as theyre not needed.
The best way to do this would be a very wide tunnel shaped ramp, where instead of slowly going upside down and staying there, have it act similarly to a loop where the g force of the rotation holds the car down. This could be done similar to a tunnel because of the immense speeds of f1. Although this would still use the downforce to complete the steering required, it wouldn’t be the primary reason the car would stay upside down
great video keep it up xD
What about rotaries?
The mazda 787b i think was one of the first cars to produce its own weight in downforce and when really pushed, it could be tuned to develop up to 900HP:
The engine in this car is not a piston an it does not rely on gravity to extract oil since the oil is actually in the fuel itself like a 2stroke,.
The only issue then, would be the fuelpump which, with a plastic bag fuel tank, commonly used in aircraft to avoid air bubbles, could function in any orientation.
I am sure thames tideway in the summer is a very good tunnel for that experiment. Also roto engines might work inversely quite well too.
I’d like to see a circuit that loops upward into an indoor section with the pits at the top,kinda like the Team Sport Karting centre but on steroids
Instead of straight section of tubular track for inverted driving, what about making the tubular section in the turn at the end of a long straight. This way you can combine aero downforce with the centripetal force applied by, effectively, a 360 degree banked turn. Kind of like how a vehicle can remain inverted through a loop section of track, as long as it has momentum pressing it into the loop consitently through the entire loop.
so, with all these calculations and number thingies and bits ... I totally expect the next video being you actually doing it
Hydrolock was an issue with radial reciprocating engines. That's why you see ground crew rotating the props. Drain out any oil that drained down into the bottom cylinders
depending on the power needed, I would have looked at one or maybe two connected power heads from a 300 Eveinrude E tec, two-stroke can work in all positions, and perhaps lighter overall than electric? I'm looking forward to it, this will be a wonderful stunt, good luck!
Surely as the car transitions up the wall, unless done quickly it needs more downside 1/2 way up as the traction on the wheels needs to be grippy enough to support the gravity pulling the car down.
For the transitionning problem in a tunnel, coul a solution be like a hot wheel loop but with a very long inverted part?
Another year has passed and yet again we're taking another step closer to irl WipeOut races.
Tge distribution of downforce is also very important when calculating the center of lift.
Make something like a treadmill for the car, that can rotate. Would allow it to be done under controlled conditions and prevent the 3 point of contact issue on the transition
It would be super fun to watch! We can start testing in automated formula series. @FIA
Can't wait for your thoughts on the farce in Abu Dhabi.
I wonder if it would be possible with the next gen F1 power units. More electric power. Realistically you could get up to let's say 200mph using the ICE, and then use the MGU-K to keep your speed above 185mph for 5 seconds. But I do think the whole "flipping" part is probably the most difficult.
Would love to see one of the F1 teams try it in their wind tunnel tho, as a proof of concept.
Forces toward the track has to be equal or greater ( not exclusively equal ). The greater the orthogonal force with respect to the track relative to the gravitational force due to the mass of the car, the easier it is to remain driving upside down. The challenge is the transition from the upright position to upside down position while sustaining the effective operation of the engine.
would an above ground construction be easier and cheaper? no need to dig a tunnel, but the supports needed might undo the advantages. another thing to consider is that the entire track would have to be asphalt, as i assume all the grip calculations are done on asphalt. and i'm not too sure how well asphalt fairs when suspended on a ceiling.
Red Bull marketing team seeing this video:
“Write that down, write that down!”
Fuel Injection, pressure carburetors, inverted oil systems exist since World War 2 to solve the problems of inverted flight and negative Gs. I'm sure any engine maker nowadays could adapt existing or older engines from past championships for this challenge.
Informative.
Wouldn’t the pressure from down force be less upside down because gravity is pulling against your laminar flow so it’s not sealing in the back end, it would be pulled down and trial off.
Or would the F1 chassis essentially be creating lift and sticking itself to the ceiling if it was upside down because all the wings are usually an upside down airfoils to creat downforce and now they’d finally be the right way up?
The McMurtry speirling seems like it would work very well but that wasn't out when this video was made
Would be cool to see this done with a pre programmed computer controlled, or remote controlled vehicle.
Since the battery doesn't have to last long, you can use a smaller battery that powers a stronger motor. You can also use a fan car (banned in F1) to generate higher downforce without extra speed.
Possibly there could also be problems like oil starvation when driving upside down. I actually dont know how the lubrication system works on F1 cars and if its a dry-sump or wet-sump system, but assuming its using a wet-sump the engine would also endure damage when driving upside down
Dry sump with multiple scavenge pumps
now my mechanical mind is wondering how the KERS motor is interfaced with the rear axels, in sync with the engine? In other words, how do you properly integrate two power sources into 1 output?
From my childhood I remember watching a hotwheels vid where a driver drives the "Bad to the Blade" F1 upside down
Cool idea for a future track.
The subtle HAAS dig at 4:15 💀🤣
Really good luck driving in the ceiling of Lærdalstunnelen. Straight walls on the side, light-fixtures at the top and bumpy ceiling. Also, it's not the longest tunnel, it is the longest road tunnel (for now)
Could the issue with the ride-height change on transition be solved with active suspension?
Aircraft engineer here, if you have an inverted oil system like the redbull Air Race aircraft they could fly inverted pretty much indefinitely. The system just swaps the cranky case breather with the sump pickup with very little effect on performance. Also if said aircraft is pulling positive g's like at the top of a loop the inverted system is not required
They did talk about two stroke engines at one time. Two strokes can run in any orientation provided a proper fuel delivery system.

Would it help keeping the car grounded on the transfer from the floor to the ceiling without losing 60% of the down force if you added the old 80's F1 ground effects?
well as long as the car generates more downthrust than its weight it should be able to do so
we could probably test this in a wind tunnel just have the car sat normally run wind over it equivlent to what it would experiance at race speeds and then try to lift the car with the equivlent weight force for the car if you can lift it then it would fall if upside down
@driver61 i know this is late but what about the speirling mcmurty
