New nose "submarining" in Melbourne collision?

Turns out Newey knows what he's talking about... again. I remember people on some forums calling him all sorts of things at the time he said it.
This could potentially be a major security risk. It's not rare something like this happens in braking zones.

there are lots of discussions about this going on in the melbourne thread, williams thread and 2014 design thread.

Whoa...

Two things strike me about the picture above...
1) almost none of the crash energy seems to have dissipated by the nose as it's supposed to because the car in front just rode up and over the crash structure. I can imagine this happening in a singe car crash with the car submarining under a tire barrier and it doesn't look pretty or end well for the driver. Given the potential problems this year with the hybrid braking system (which was found to have cause this crash incidentally) I can see accidents like this happening frighteningly often.
2) the front end of the Caterham looks so much better without the stupid vanity panel! Much more like the narrow and low noses on the pre-2009 cars.

Different angle. Look where KOB's head is. Scary.

The very first fender bender resulted on that. It's the perfect storm. Unreliable systems catapulting cars along the starting field and the low noses with matching rear impact structures.

Just look at the rear end of those cars. Every single aligned ram in will result in submarining.

I didn't know Newey had said this would happen until recently (shameful of me), but I did think that as their job was to almost destroy themselves in an impact, this sort of thing wouldn't happen. Happy to be proven wrong, the noses seem to just go from one extreme to the other, though.

First, you can't tell how far the tire is from his head in a shot like that.

Second, this wouldn't be a problem if they just used closed cockpits.

Not seen that photo of the massa rear ender before. Cant believe there wasnt more reported to charlie whiting about how close koboyashi was to getting a face full of wheel.
newey predicted this, I wonder what will happen if this type of incidents occurs again?

Nose tip should never be lower than rear crash structure. Or at least higher than the top of the diffusor so that it can't submarine. Guaranteed this will change in 2015.

You wish. It would interfere with the all mighty diffuser. Unafortunatly, they wont touch it.

This picture is crazy, Massa's car is completely off the ground. Any higher in the rear and it seems that compression fractures in the lower back could become an issue once the car slams back down.

[humble sabot]

he means by the regs changing the nose height rather than the diffuser height. We have low noses because they got too high, we had high noses because we wanted more air under the car than we had with the previous low noses, which everybody thought looked better. So now we have a situation where all the aerodynamicists are addicted to feeding as much air as possible under the car with rules that were supposed to make the cars look more like the old ones. Matching the nose height to either the top edge of the diffuser or the light on the rear crash structure seems like the most logical solution to the clear safety issues posed by last years skewer noses and this year's launch ramps

Or flat bottoms. All the way.
