Car explosion after crash


Do the real cars blow up that easily after a bad crash?

reply

definitely. In 1971 Herbert Muller had a big crash on the starting line of the 1000 KM at Nurburgring, his car exploded and he escaped the fireball with flames surrounding him. Unfortunatelly he died 10 years later in a similiar accident in the same race. Another example is the death of Pedro Rodriguez at Norisring in 1971, while Henri Pescarolo suffered burns on his face (can be still seen...) while testing the Matra at Le Mans. Le Mans is a very realistic movie and you can really understand how that race was (and somehow still is)

reply

John W Steed is correct. Plus, let us not forget Nikki Lauda's horrific crash at the Nurburgring.
Self-sealing fuel tanks are a very modern invention, and the cars of the era portrayed in "Le Mans" did not have them.

reply

No, generally not.

That is they certainly had a terrifying tendency to burn (often with huge columns of fire) but as an actual explosion, not commonly.

reply

In real life, most cars might not of blown-up in that fashion (the explosions in the film look like a bomb going off), but yes, in those days cars caught on fire often.

To add to what HMS Surpriser wrote: what's worse, especially in open-wheel cars at the time, the tanks were normally positioned in the sides of the cars, one of the most exposed areas of the car, easily suspectible to damage or puncture in an accident.

That first fiery crash in the beginning of the film, the one where McQueen stops at Maison Blanche and has a flashback to the accident involving him in the previous year, has some connection to a real accident that happened in Le Mans in 1969.

One of the Porsche 917 cars was to be driven at the start by the inexperienced John Woolfe.
That was the last year that the drivers ran to their cars at the start (some would not fasten their belts in order to get off the line quicker).

The 917s were unwieldy to drive that year, Woolfe lost control at Maison Blanche on the first lap, crashed, and the car split in two; Woolfe was thrown out and killed. The fuel tank also disconnected and caught on fire.
Chris Amon, driving a Ferrari 312P through the wreck, could not avoid the burning tank and had it lodged under his car, but luckily, he managed to get out of the vehicle without injury.

Burn, yes; explode, no. By 1970, fuel cells were used in most sports cars. It will take some research to determine if FIA required these at Le Mans in that year. These were steel boxes with rubber bladders. In a crash, if the box were hit sufficiently to deform, the bladder contained the fuel. Check the ATL website.

Grand Prix cars and Indy cars, did not have such cells until much later. Siffert and Lauda were burned in GP cars.

If you watch the pit stops closely, you will see that many cars used "Monza" type, flip open gas caps. Unsure of the year these were banned but probably before 72 when I started racing. In a rollover or heavy impact, the caps could pop open, sometimes releasing fuel and providing a flame path to the inside of the fuel tank. In general, fuel will burn unless it is under pressure. Explosions are possible in theory but in all my years, I never heard of one.

reply

flat0903 - Are you able to explain why the drivers had to get out of the car and have the engines turned off while pitting?

Also, many years ago, I saw a demonstration to demonstrate the strength of the fuel bladders are. A weight of metal was suspended from a crane and dropped 20 or so feet onto the full bladder. It did not burst. The weight was ten tons.

Snore, it's a LeMans specific rule that the drivers are required to shut the car off and exit during refueling. I don't know if it applies anywhere else, but LeMans has had that rule for a long time.

reply

Thanks, rockmail. But do you know the reason for needing to alight from the machine?

If you have some spare time and donero, this time next year in New Zealand, there will be a celebration of Bruce McLaren & his contribution to motor sport. It will attract the largest collection of McLaren race cars, other cars from a fabulous bygone era & there is a brand new race track built at a cost of one hundred & fifty million dollars to host the racing.

That is done during a driver change. It allows the crews to work on the cars. If I remember correctly, they can't do any work on the car while the driver is seated in the car.

reply

At Le Mans, the ACO (Auto Club of the West) requires all pit stops to be done with the engine off. Whether refueling, tire changes, work on the car, or driver change, turning off the engine prevents static electricity from igniting the fuel, misalignment of the wheels or crewman's arm injury if wheel spins, or driver managing to move the car forward on the jacks while stepping out of car or jumping a gear in launch. Having the car in operation just isn't good for anyone while maintenance is performed. Turning the car off allows for a safe pitstop and places an extra test on the machinery as it wears and tears through an endurance race. That's just how the ACO does it and rarely have you seen an ACO sanctioned pitstop at Le Mans or anywhere else on the FIA World Endurance Championship calendar, European Le Mans Series (Le Mans Series), or Asian Le Mans Series, where safety is of concern.

At times, there's often launch sequence ignition problems after refueling especially in the GT category last year there were a few in World Endurance Championship, where the fuel leaking out still ignites when the switch turns on, but there are safety mechanisms on the GT cars to deploy for extinguishing those fires immediately.

24 year old Belgian F1 driver Jacky Ickx won that race in 1969 by walked gently across the track and staying on the starting line until he buckled into the car safely. He had a ways to go, virtually a lap lost, but he spent the entire race fighting back to the lead and won it outright with another Jackie, Jackie Oliver and the Ford GT40. That political statement amid Woolfe's death ended the Le Mans start and installed the running start we see everywhere.

reply

The awful crash at the 1st start of the 1982 Canadian GP.

John Watsons McLaren, Italian GP 1981

Lorenzo Bandini 1967 Monaco Gp.

Niki Lauda German GP 1976. Niki was back in the 312 Ferrari 6 weeks later!!!

British GP 1973.

To name just a few. So sometimes they do blow up easily.

Very ghoulish stuff to watch.

Actual explosions are practically non-existant. None of the incidents you cited involved explosions, snoreflottado. It's a Hollywood thing, they believe every car must explode when it hits something. In the real world, it almost never happens. I would have thought that Steve McQueen understood this.

reply

Yeah, no worries. Agreed. I misinterpreted a 'fireball' & 'blow up' in the original question.

'The Simpsons' seem to understand & agree with what you write - having the absurdest things explode at the proverbial drop of a hat.

My favorite being the milk truck in season 1.

I was at the race in Montreal in 1982 when Riccardo Paletti burned to death. I'll never forget the smell of the black smoke. So yes, cars will burn in a crash, not usually, but sometimes, and when they are full of fuel at the beginning of a race, it's blazing fire.

reply

Cars, like many other things, burn. An explosion is extremely rare, unless you are talking about drag racers.

reply

This is really the closest thing I've seen to an actual "explosion" but it's really a big fireball. Horrendous, but both drivers survived. I find it very difficult to watch Tetsuya Ota once they get him out of his car (The red Ferrari that is the last one into the wreck and burns the most). I don't like the music being added but I haven't found a video of this without music.

I am not old enough to remember this era through my one experiences, but since the late 1970's I've been to literally hundreds of races (I used to attend my local track weekly for 10+ years) and seen many hundreds more on TV and cannot really remember any "explosions" but many fireballs.

I just watched this movie for the first time. I'm a big F1 and Le Mans fan so I appreciated the focus on the racing and almost total lack of dialogue.

When the crash happened and the driver attempted to run away frantically, I was trying to fathom WHY ? You've just been in an accident, you're injured, relax, help is on the way. Then I started to thinking "Its not going to explode is it ? It shouldn't. Seriously, it shouldn't..." Then BOOM!

As explained by others, they shouldn't explode. Sure, they can I GUESS. Burn, yes. It was an older, less sophisticated time but still, explosions didn't happen. A car (and driver) being engulfed in flames of course was a possibility, as evidenced by Lauda and others especially if the tank is ruptured but if the car had exploded I doubt they'd still be alive today. Most drivers die from the violent high speed impact and nothing more. They wear flame retardant clothing, not bomb proof. Your average fuel tank in an average car is designed to be safe, not 100% but close to it. Plus, most explosions come from things that are compressed.

Thats why its made fun of in comedies (Simpsons did a funny one on this, car runs off road, stops barely in time a foot away from a tree, driver exhales, then BOOM!!) but still shown in many a movie of course. Why ? Its dramatic and gives a reason to use explosives. Think of all the accidents you've seen or heard about, on the streets and in racing, how many times have you seen a car explode (or even on fire) ? Rarely, if ever. But in movies ? All the time.

reply

The same as tanks in WW2 films, Shermans caught fire very easily, but they DID NOT BLOW UP, as most movies have them doing. Unless, that is, they had HE rounds on board, but even then I believe it would take several minutes of intense heat from flames to charge the steel cartridges, so the instant explosions we see are just Hollywood fantasy, and the result is they've fooled many people into thinking it really happens.

reply

There is a fabulous scene in a Simpson's episode where Otto's bus is parked, bonnet up, wheels off, up on blocks, & a single leaf from a tree lands on the roof - kaboom!!!

What about the milk truck that crashes into a water hydrant.
