yea but isnt that a form of a crumple zone? i mean if the bumper were just metal, the crash would have a HUGE jolt for the passengers. the way it is now, the car will crumple up a little, still no were near as much as a range rover or some other SUV's with crumple zones.
I understand why metal would be better for a lot of circumstances, but safety i dont think it is. I think Nissan would have a lot of problems if they had a steal bumper on one of there stock vehicles.
Check the ARB web site and you will see that they crash test them to ensure they crumple in a severe accident. Why would you want your bumper to disintegrate in a low speed accident? Wouldn't it be better to hold up in low speed situations, and crumple in high speed situation? Who would benefit from that kind of thing, a dealership/parts department? No, its the governments fault a 5mph accident just cost you $850 in parts. We have to design them to meet those standards right?
