2010 Roof Crash Test Results

[Carlover0529]

Bigretardhalo is a big retard. Duh.

- If vehicle's unloaded weight is less than 2722 kg, than it is subjected to its unloaded weight x3

-If vehicle is between 2722 kg and 4536 kg, than unloaded weight x1,5 is used.

[Enjoyification123]

Haha p.o.s Kia

[copocol]

what a fake advertise,  just compare different time of pressure

[Apugueiro]

the tiguan is almost intact

[Apugueiro]

what a difference!!

[JENSDONT]

Love the Tiguan!! German quality!!

[SteelCity1981]

Sounds like ice cracking.

I guess someone died in that KIA? huh?

[buffyfoo]

@2002altima yepppp,, not the tiguan though, its amazing it got scruched a couple inches, way to go german engineering, v-dumb (i beleive) are the safest cars out there. ... les general, all german cars taht are newer are very safe

[neptoon07]

@mrdestoryit kia doesn't suck they are working very hard to make better cars the 2011 KIA Sportage got the Top Safety pick.

[nick76dune]

kia once again prooved its name for

KILLED IN ACTION

This test seems almost pointless... you might as well static test the bumpers too. They don't for a reason. All the cars will weigh different amounts so if it is on it's roof in a crash it is supporting it's own weight. So just saying not deflecting x amount under 15,000 pounds of force is stupid as it would take a much more violent crash to put 15,000 pounds of force on a Lotus Elise's roof than it would the roof of a full size SUV or even a full size car for that matter.

[tomytots]

You are correct if only considering a single vehicle accident roll over.

There are many situations where the roof is required to take a lot of force. Consider a truck tipping over on to your car for just one out of many possible examples.

You are right though, it would be more practical to know if a roof can hold its own weight. However, I think its a given that every vehicle can.

[bigretardhalo]

Well I can see your point but I do not think it is a given.... personally.... I think some cars would fail in that respect. If they are worried about collisions with a truck than 15,000 pounds of force even is pointless since the load in a semi trailer at max weight is 80,000 pounds. so even a half loaded semi in a slow speed crash or fully loaded straight truck would easily double the force of this static test. Again my opinion thanks for the other angle to look at I hadn't thought of that.

[BoberMcBoberson]

They didn't fully explain the test here. Your right it would be pointless to just drop a set 15,000 lbs on every vehicle. but that's not how the test is done (thought it looks that way in this vid). What they do, is test to see how many times the cars own weight it can hold. 4x and I'm not sure how many inches of crush Is considered a pass. Some cars make it bond 4x and some are flattened at 2 or 3x, hope that was helpful.

[bigretardhalo]

Thanks for the great explanation. I wish the video would have given vehicle weights and test results and scores to show us how they use this rating better. That does make more sense. I would still like to see some form of moving test like they do for front and side impacts as vehicle design can greatly impact which area of the roof takes the largest amount of loading. Thank you for the explination this test makes more sense now. I do hope they are working on a moving test though.

[Spyster007]

The pass mark for this roof crush test is not a standard weight but x amount of times the vehicles weight, so it still is gauged against the vehicles size, a lighter vehicle is allowed less force on the roof to pass the test.

[LoveTheCity123]

@bigretardhalo This test is not pointless. It is a extremely good test because it lets people know how their vehicle will react in a roll-over.

[bigretardhalo]

@LoveTheCity123 no it does nothing to show how a vehicle will react in a rollover it mearly shows the amount of weight the roof can support at a given amount of deflection. The fact that it does nothing to show how a vehicle will react was my original complaint.

[LoveTheCity123]

@bigretardhalo You don't understand what these test are for. They are putting 4x the weight of the car on the roof to see how much the roof would come down during a rollover, but sometimes when cars rollover, the usually land on their roof on one spot really hard, then comes the whole body, giving all of the weight of the vehicle on it. Believe me, these test really do the actual thing.

[bigretardhalo]

@LoveTheCity123 and you can do the same thing with a bumper and it will tell you the same thing as far as overall strength of the bumper even though the crash results may or may not be completely different at speed. That is why they crash test cars moving because two cars that have bumpers that hold up the same in a stationary test can have different scores due to how the load spreads from the bumper to the body when moving.

[buffyfoo]

@bigretardhalo the different weighed car are in things called "groups" the smaller car group, midsized group, and larger/luxurious group, and same with suvs, u should look into that

[bigretardhalo]

@buffyfoo please point me to the place in the video where they explained that thank you.

[jaffacake1578]

@bigretardhalo yes thats why they only put five times THE CARS WEIGHT on it

[taitai907]

@bigretardhalo As far I know, They put 4 times the cars weight on it.

[tigerboyz12]

i can't understand the graph

[whynot9899]

The graph showed two things in relation to eachother. The amount of weight, and how far it was broken, or pushed in when it was sustaining the weight. When the kia was at 5 inches of penetration it appeared to be holding about 8,000lbs from otherwise pushing the roof into the cabin of the vehicle. As the weight pushed deeper into the cabin of the kia strength increased probably from the compacted frame. This is best illustrated by crushing an aluminum can as small as you can and cant do more.
