In my highway travels I've seen lot of crashed Etios cars, most have taken the impact well with crumplezones working, and structure retaining its integrity. Quote:
Try driving a Etios without people on the back seat, the rear end just doesn't want to stay in line, if you enter a curve even at moderate speed it tends to oversteer, a inexperienced driver even touching the brake at this time will send it out of control. Its sibling the Liva is quiet stable in this respect. Rahul | ||

A pic to show where the said "zones" lie. The yellow and magenta marked are crumple zone components. ![]() I think that before the said zones are compromised, the impact has to go past at least the radiator and condensor with oil-filter, sump etc mostly joining the party. Nothing of the sort seems to have occurred here. In this case only the outer cosmetic components like bumper, headlight, grill, etc are damaged. Not sure if these too come into crumple zones though. If they do, I stand corrected. Last edited by bblost : 20th February 2018 at 19:00. Reason: formatting issue. | ||

Thanks for the update. I am happy to learn something new. However, I am still not sure if you have got it right. Maybe I am using the wrong words. Maybe 'crumple zone' is for protecting the car occupant. I am talking about the pedestrian protection. Your beautiful writeup has me confused. No offense taken or intended.

You're looking at the wrong thing in the diagram. You should be looking at the red circles that roughly indicate the crumple zones & passenger compartment. Quote:
The car has to absorb impact, and that happens in stages too. Eg. the bumpers absorb the softer impacts (or the initial impact in case of larger impacts), followed by other parts of the front end of the car, and then the crumple zones (perhaps even in stages). That said, the more a car deforms (in a semi-linear fashion) while keeping the passenger compartment intact - the better job it's done at slowly decelerating the impact for passengers. And when I say "passengers" -- in this case it would apply to the passengers in the Creta and the autorickshaw! Last edited by Rehaan : 20th February 2018 at 17:04. | ||

Please see the video posted above. The Creta just bumped the Rick and crashed into a concrete structure and sustained the damage. |

Coming to this case, the curling up of the bonnet, fenders and tearing up of the bumper all absorb crash energy. Hence, they are bound to get destroyed. As to why the auto rickshaw did not suffer damage, that is because the Creta hit the strongest part of the rick, ie the place where the medieval(read - Heavy) diesel engine lies with the entire transaxle. That is why it was pretty stable, except from suffering loss of directional control, which is obvious due to the hit. Had the directions reversed, ie Creta getting rear ended by Rickshaw, it would have been a different story altogether. | |

Because it was set into action here. From the 3rd pic, I could clearly see how the front-end cross member bowed inside. A thorough in-situ inspection would've helped further! Quote:

AFAIK, crumple zone implies the space between outer shell and passenger compartment and not merely any components but the components do share their part in assimilating the crash energy. Please correct me if I'm wrong. Last edited by Pferdestarke : 20th February 2018 at 17:55. | ||

Distinguished - BHPian ![]() ![]() | ![]() Guys, before it turns out to be another tin-box / European build debate. Damage to Creta, in the Creta- Piaggio accident above is not just due to impact between two vehicles. If you watch the video of the accident, you can notice that Creta took most the hit after going over an embankment. That will give a better understanding of the damages. Video of the same is shared by Parag in above post - Link |

| ![]() I don't know why people are still screaming "crumple zone". I strongly suggest people Google up "crumple zone" to see actually which parts are termed as crumple zones. I didn't name them myself. I see them everyday as it is part of my daily work schedule, kind of. As for the concrete "embankment," it was not a direct impact and acted as a big speedbreaker for the left front wheel, is what I can see. If it was a direct impact with the concrete thingy, the rear of the car would have lifted quite a bit more on impact and overall damages to the Creta would have been much more and it would have stopped right there and possibly even rebounded a few inches on impact. Here, it rolled forward. I think everyone has a different take due to the nature of this crash so there's no point breaking our heads on it. Everyone has their own view point and so in this case the discussion is seeming futile. Others might carry on, I'm done. |
