I believe there's a Porsche GT1(if I'm not wrong) car, which flipped and landed again, but spun out and went into the wall.
Even if somebody managed to flip a car like that and land on it's wheels, it would be undriveable.
The impact would destroy the suspension and most likely bend the chassis so bad, the wheels wouldn't even touch the ground, or atleast beyond the point of being able to steer.

I like how it took 3 cars to flip through the air for Mercedes to realize there was something wrong with their design.
I think they know their design is too aggressive after 1st crash. I'm rather curious why they can't do more to fix the car, like extend the length of rear suspension or something. Maybe they were already not the fastest cars, to fix the problem completely will make it much slower. So they only add the little frong wing only, and pray for miracle that never happened.
Because third time's the charm.
@@Richard-Gore they knew after the 2nd, because they didn't believe the 1st happened. No footage, light damage and the driver's word for it. Also, the car was still the fastest after they modified it (not enough) after the 2nd crash.
@@Richard-Gore I think it's because it was too late to fix any Fundamental flaws with the design so they put a bandaid on it and hoped for the best, which of course wasn't enough.

Here starts the explanation 3:50
You can simulate this happening perfectly in Project CARS 2. If you have the front rebound forces very high, with a high rear downforce balance, the air can get uder the car and...well fill in the blank lol.
Well.. i know what i'm doing tomorrow..
Wouldn’t high compression and low rebound damping on the front end tend to jack up the front of the car and encourage a flip?
@@mosca3289 was thinking the same thing
I did this in assetto corsa with the URD Mercedes Clr was crazy
You mean "the air CAN'T get under the car"... meaning that there is a diminished flow speed which increases the pressure culminating in a "lift" resultant force.
Man, the Germans really like sending Mercedes engines airborne in Western Europe, huh?

Wipple Wopple this is an underrated comment
Great comment, but.... Mercedes never made aircraft engines during WW2, only junkers and BMW IIRC
They all got shot down
You'd be amazed at what can fly in the right conditions. I once saw an inflatable river raft with 8 people lift 6' above the water in a head wind, hover for a bit and then flip over dumping everyone out before landing again.
The Porsche 911 GT1 also experienced a similar flip at Road Atlanta, so GT1 had well and truly gotten out of hand aerodynamically by then.
Im glad there now exists a video that clearly states it was the CLR that was flip happy, not the CLKGTR.
Im sick of seeing blame pointed where it doesnt belong all the time. 😐
Wait someone blamed the CLK GTR? That's facepalm worthy for sure 🤦🏻♂️

@@Raprada i see it a lot and it's definitely facepalm worthy
I also saw this happening a lot (mainly 10-12y ago when I was more into watching racing videos) and even remember the CLR being referred to as "CLR-GTR" in the title of one video. The CLK GTR and the CLK LM are quite similar although a trained eye shouldn't have trouble distinguishing them, but I've been always puzzled how many people mess up "CLK GTR" and "CLR" so often...it seems to be more about supposed appeareance similarities than name similarities, but the GT1 cars are SOOO different from the CLR!!! Totally don't get it about how it happens so much!!!

Ouch

Wait didn't like a BUNCH of people die when it happened in 1955? o.O
@@a.ndy.nonymous 84 people yeah.
Mercedes and Le Mans together were "benchmark" for safety measures in motorsport.
The famous 1955 disaster defined the whole destiny of motorsport and safety on tracks.
Well it took them a staggering 40 years until the safety on and round the track started to get to an acceptable level. Not impressed if your story is correct..
1955 wasn't Benz fault as it was proven later on
Other than a few circuits adding a chicane before the pits nothing really changed. Like the Goodwood chicane
I don't think motorsport should be unnecessarily dangerous but i do think it shouldn't abandon sport in pursuit of safety.
Safety is nice but people don't race or watch racing because its safe. So its of secondary importance to the sport itself.
If we only did what was safe we'd never have done anything, and we'd be extinct while we were still cavemen.

**Mercedes Car flips for the second time**
The team : _"I'LL FKING DO IT AGAIN"_
And this is why modern Prototypes have squares cut out above their wheels. To release the build up of pressure in a situation like these.
Thought I'd check to see if anyone else had already said that. Dumbreck was incredibly lucky that the owner of the trees (local govt? I honestly don't know) had cut down a bunch of them recently and he landed where they had been. When I heard that on the weekend, my blood ran cold!
In addition, the front overhangs were shortened to reduce front lift.
@@chrisdeo wrong. cars must have it as a safety measure. one would also release pressure to reduce drag behind the wheel (cut out wheel arch), not on top of it.
This is an old aero trick. The Dodge Daytona used this back in the day for added down force.
They are already in use but you are correct.

Jiggmin1234 Its funny enough that Webber is now notorious for flipping cars. Hell he flipped Redbull in 2010
@Chain Bear This is quite good as far as it goes - and it goes a lot further than most on this subject. Pitch sensitivity is one part of the problem. Static aerodynamic stability is the other part. As far as what initiated the take off is concerned, everything that matters has been covered. The only caveat I have is that you said the lift at the front of the car overcomes the _downforce_ but in fact the change in pitch angle probably does that anyway. What happens then is that the lift generated by the front of the car becomes greater than its _mass._ What happens after that is the bit people miss.
Pretty much all racing cars these days have a rearward weight bias. Even the front engine Nissan GTR that flipped at the Nurburgring with tragic results a couple of years ago was probably running a rearward weight bias. These days it's usually a function of all the heavy components being placed at the back. Rearward weight bias is generally desirable in vehicle dynamics... as long as the vehicle stays on the road.
You quite rightly pointed out that once the car starts to lift, the centre of aerodynamic pressure shifts forward. That is a classic illustration of dynamic instability. However, since the aerodynamic centre of the car is already forward of the centre of gravity, the car is statically unstable as well. Were it not for that fact, I believe the car would simply come crashing back down onto the road. That may have just as catastrophic results as flipping but the point, of course, is that this shouldn't happen at all.
Just to attempt to make this a bit clearer, when the CoG is forward of the aerodynamic centre, the vehicle is stable and should return to its original trajectory. That is called positive stability. When the CoG is aft of the aerodynamic centre, the vehicle is unstable and its trajectory is difficult to determine but it will be unlikely to return to its original trajectory. That is called instability. It's known in aerodynamic circles as divergence or flutter. This phenomenon has been tested in aircraft since 1914, long before they could travel as fast as a modern racing car.
The trigger of the flip is well discussed but the static instability of the car is what causes it to tumble. To me this represents poor design.
1950: "i bet we will have flying cars in the future
1999: "well yes, but no"
Webber is a pro at doing backflips with racecars
He can do backflip himself as well, when he won Monaco.
One year at Petit Le Mans a Porsche GT1 flipped in the exact same way.
Fishsticks yes, that was 1998, so that was actually a precursor to the Mercedes acrobatics the following year.
And a BMW V12 LMR crashed aswell
Jann Mardenborough also had a very similar crash in 2015 in a GT-R GT3, over the hill before flugplatz at the Nordschleife, sadly that one killed a spectator
Hellisoy yep, that was 2000.
that wasnt as bad since it was due to close drafting behind the opther car, the mercedes was even worse because it flipped on its own
Two things:
I knew a guy who used to run formula, Atlantic and IndyCar, he explained a lot about aerodynamics, and there were two aspects of this that people may find useful….
If they were running under body downforce, it behaves very similar to a magnet; great up close, not very great far away. And, the amount of pressure you generate is specifically dictated by the distance to the road surface. The closer the venturi tunnels are to the ground, the better it produces downforce. In this case, we see the effects of that full force: once the body got far enough away, it stopped production entirely and rapidly. This could be due to the pitch of the road and dirty air from the leading driver more so than the pitch in role of the chassis. I would doubt the suspension had enough pitch and roll in that spec - necessary to handle the weight of the downforce generated - to cause it to pitch and roll that violently.
The second compounds over the first, which is that an order to generate under body, downforce, the bottom of the vehicle has to be completely flat with as few open pockets as possible. This means that there is no place for air to escape under the car once it gets there, and this is by design. Once the front end had enough air, moving underneath it, as you said, it became a lifting device instead by virtue of the fact there was no place for air to go, and it began to create an air cushion more rapidly.
Hard to focus on the video when you have an ad popping up every 60 seconds. But, from what I could see it was a very informative video.

This also happened with a CanAm car at Le Circuit in Mont Tremblant, Quebec back in the seventies, before I went there for racing school. Le Circuit has the largest altitude difference of any racetrack in North America -- 85 feet! -- with at least one decreasing-radius off-camber turn that I clearly remember. As we walked the track on the first day the instructor showed us where the car caught air on a short but steep hill in the middle of a turn and flew like a paper airplane right through the tree tops for about a hundred feet.

This wasn't the first time that a race car flew away during an endurance race. In 1953 John Fitch made quite similar attraction with his Briggs Cunningham C5-R at Reims. Umberto Maglioli followed him and couldn't believe when the Cunningham took off, flew above the trees and telegraph posts then smashed to its wheels near the track in the fields. Fortunately Fitch had just minor injuries. In WW2 he was a fighter pilot and I guess he was the only fighter pilot who took off with a race car (and crashed that).
Red Bull secretly gave Mark Webber wings 😂.
I have a clear memory of watching that race. During the race, the Merc was on a part of the track with no spectators, but there were cameras. It reached the top of a small hill, and just kept rising. It DID NOT flip. However, it brushed against some trees, which made it spin like a frisbee. After reaching a height of perhaps 20 or 25 feet, it drifted off the track and landed, still on its wheels. By the time the "rescue team" arrived, the driver was sitting on a large rock near the car, shaken but uninjured.
Perhaps the most amazing thing I have ever seen, in many years of watching or attending motorsports. (Does anyone remember "Speed Week" in the Bahamas?)

Good vid to explain in detail what happened. I wonder who the race engineer for Mercedes was at the time?
Good explanation!
Great explaination! I can still remember seeing this crash during the live broadcast, it probably is the single most terrifying moment I've ever seen. Even all these years later, it still looks scary as hell every time I see it, and it never ceases to amaze me that Dumbreck survived this pretty much unharmed. While I have seen several fatal racing accidents happen live on television, the true horror of those crashes always came later on.
The Toyota TS020 had already the wheel arch cut-outs in 1998. I wouldn't also say that the CLR was expected to "flatten" the competition. After '98 and Porsche's exit, the Toyota's were pretty much the car everyone had their money on. And rightfully so, if you compare the TS020 chassis to anything else in that time, the TS020 remains a timeless beauty and a remarkable piece of design.
Great graphics/animations.

Now for a follow up looking at how a similar effect caused the early Audi TTs to fly.
I like how you just barely mention that Adrian Newey told them to withdraw. If one of the leading aerodynamic engineers of our time told you to withdraw, probably because he saw a problem, you should really listen.
Just saw the video and I had exactly the same thought hehe.
Well, I think he was working for some team at the time, so they wouldnt listen to a competitor telling them to withdraw...one rival less to beat i guess
@@Hernandeces He was with McLaren, who at the time were officially partnered with Mercedes and racing in F1 as McLaren-Mercedes

WOW! Great video.
I had no idea they reduced the height of the Mulsanne Crest as a result of the crashes! Seen the footage a thousand times. There's even footage that shows Webber's car on its head (but not the actual crash).
To add to this: The rectangular holes above the front wheels of prototypes , and louvers on gt cars, serve to keep air from packing into the front wheel arch creating lift. I am not sure on the date of implementation but they were added in the same spirit of safety targeted at limiting front end lift.
Thanks for another great video.
Yeah it’s odd. Most comments here refer to changes that really kicked in after the Toyota crash with Anthony Davidson as well as previously when a car took off in the Porsche curves. It took a couple of years really for the ACO and FIA to realize that this issue was a real problem. They introduced the cutouts over the wheel arches, the dreaded giant rear fin (to break air flow over the car and try and stop it taking off). One other major change was the floor. If you look now, there is a raised section on pretty much on all categories at the front. As well as stepped floors (no longer a giant flat area), the sidepods of the cars are now curved at the base, not 90 degrees. They have a curved radi to them and are no longer touching the floor. Again all designed to try and reduce underfloor downforce and reduce pitch sensitivity and the risk of taking off. Prototypes and Gt’s all have the same issue. Big flat underfloor area, get air under it and the car will try and lift. I have no issues with the changes as they’ve worked very well, just wish that rear fin looked a bit nicer. Lol. Oh and in case anyone’s forgotten, the Courage taking off at Monza. That was by himself, got sideways I think, air got underneath and he took off. A very scary accident too.
