RIP Paul Walker

Oh man! You never really realise just how at risk you are in cars like that, I know it's a tough material but weight saving and positioning is a big gamble. Makes me glad I'm in a big saloon full of safety gear, at least at those speeds I might have a small chance depending on point of impact. How mad were the old school f1 drivers!?

even though they are road legal they should be RACED on the track where rubber tyres and the gravel pit is effectively your crumple zone. But seeing the chasis like that.....:eek:
 

Watching vids like this one is really bittersweet. Glad that they had so much fun, sad because they can no longer have that camaraderie. At least all of the casts in the various films have good times to look back on, even if you weren't a lead role.

Not much of a crumple zone! Nor side impact strength


Have you any idea how daft that sounds by coming out with that and just posting a picture (of what looks like a pretty open cockpit I must admit) as justification

Carbon tubs are waaaaaaaaaaaaaaaaaaaaaaaaay stronger than that of any steel box of a normal car.
Components are designed from the very outset to shear off that tub to take away the impact forces imparted upon it.
The crashed car looks a bloody mess because it did what it was designed to do and that was to come to bits.
However it sounds like it was the fire that killed him.
Any normal car and he'd have been dead from the actual impact.

I'm not sure how it's stupid. It just shows that once the superficial panels are removed there is very little else.
I guess you didn't read the earlier posts regarding carbon fibre. In that layup with probably a 6mm honeycomb it offers very little energy absorption. Obviously it is massively stronger than steel in the right load paths but steel can bend and take energy.

This is why the engine ripped out from the car. The spars will have very little side impact strength and the whole car lacks any real crumple zones for side impacts. With an impact and torsional stress on the car it's no wonder it looks a mess and it wouldn't need to be going that fast to do it

Then with fuel going everywhere you have a fire which starts the glue and coal burning (carbon fibre ). Again making it look even worse when we see the aftermath.

It will be interesting to see if they do put a speed estimation on the crash as I genuinely don think they have to be going crazy fast for the car to end up appearing like it did.

Interestingly the Aventador uses a carbon tub but with a space frame rear section and the tub looks a lot more substantial with decent sized sills which are part of the car. (This is first hand from what I saw in the factory on a tour)

In any case I think the passenger would have had no chance in any car but without the fire I think the driver could have got out.

Is that why BMW just ace'd NCAP in the i3? Oh no didnt think so. No doubt they could engineer the NHTSA pole test but once you get much more than 10 degree angle of approach on a test like that the carbon structure is working in its worse case - Compresssion.

In steel you use elastic and plastic deformation, in carbon you rely on the disintegration of the substrate to absorb energy as the microfractures in the material are the energy conversion. Problem is you end up with not much car left and hence there is real incentive to jettison the engines to reduce the kinetic energy the safety cell has to deal with. Typically the fact the fuel line from tank to engine doesnt break how its supposed to has a real chance of starting a fire as only a few ml on hot exhaust systems is enough to start big fire.


Back to story.

Still gutted by this really.... dunno why its effected me so much? :confused:
 
Mechanical failure. Explains a few things. I did wonder how an experienced race car driver, could easily loose control.

True, you wouldnt expect someone with his experience to 'bin' it, however having said that...

Cops said Rodas, 38, had been speeding

If he hadn't been hooning it on a public street, they both would have been alive today. Just goes to show kids, don't race on the street, race on a track.
 
Can't see enough to make any judgement on that, really.

Unfortunately, it does sound like a particularly poor decision to let rip in a Porsche on a public highway for the purposes of troubleshooting. A recipe for disaster, that truly ended up in one.

RIP to both of them. I'll always remember Paul for the F&F movies, and especially the utterly fantastic "Running Scared". A real shame.
 
Didn't think it would take long before the "accident" was blamed on some sort of mechanical failure, after all these Hollywood people are completely faultless and always awesome fantastic people.

mate if u lost control doing just 30mph and hit a tree you would 95% live to see the next day.

there is a reason for speed limits.

yea maybe u can over it by 10mph but looking at all the reports and damage, they probably going near 100mph.

that car would not explode in a simple 40mph speed

And if it was a mechanical failure on a track you could still end up dead.

I take it you stick to the speed limit on every road you drive on?
 
I thought that the film was in post production which is like editing now??

Stelly

Says it's in production, think thats just before post-production. I can't get over Kurt Russell is in this.

Susan Cooper (pre-production)
2014 The Expendables 3 (post-production)
Lee Christmas
2014 Heat (post-production)
Nick Wild
