对比一下此贴就知道后保险杆有没有用了,呵呵,你看后面的凯越头都快撞烂掉了,550的后玻璃都没有破吧,我是新手其他看不懂,反正550的车皮敲一下就知道厚梆梆的,有安全感啊,呵呵。

英文不是很好,这里说的只是保险杆,似乎没有防撞梁什么事啊!这防撞梁又是从哪里跑出来的?似乎根本没有所谓防撞梁的说法,只是车黑的杜撰啊!
Front and rear bumpers on today's cars generally consist of a plastic cover over a reinforcement bar made of steel, aluminum, fiberglass composite, or plastic. Some automakers design the bumper bar and its attachment brackets to crush in a low-speed crash to absorb energy. Polypropylene foam or formed thermoplastic sometimes is used in addition to or instead of crushable brackets and a bar. But frequently their main purpose is to serve as a spacer between the bar and the bumper cover and not as an energy absorber. Very few bumper bars are attached to the vehicle structure through mechanisms like shock absorbers.
这是原原本本从iihs官网上拷贝下来的。保险杠是指塑料外壳+加强杆,也就是我们所说的防撞梁,两个是共同作用的整体。保险杠的作用是在低速碰撞中保护脆弱而又昂贵的车身部件,所以一个合格的保险杠应当有足够的硬度、高度、宽度和长度。iihs的解释中没有提及保险杠在成员保护中的作用,所以基本可以肯定保险杠的主要作用是保护车身而非成员。
像前面某位550车主所给的链接中,550的尾部防撞梁够硬,而且够高(这其实是很关键的),后车追尾时,很容易插到保险杠下方,这就能够减轻自己车的损失(而且加重了后车的损失。。。。)。思域最大的弱点也在头部,一旦追尾他人,车头太低很容易在急刹之后钻到别人的屁股下面,所以开车的时候务必要小心。至于尾部,没有后防撞梁在小碰撞中吃亏那是一定的,个人还是建议要安装。

IIHS在美国是由保险业介入的,IIHS的成绩直接和保费挂钩的.....所以一个bumper spacer显得如此重要。
无论是在欧洲还是美国的测试当中,并没有体现bumper spacer对于乘客的保护。事实上个人认为后备箱的缓冲要远好于单独的一个防撞梁。
由此基本上可以得出这样的结论,在国内保了车损险+不计免赔的,bumper spacer就是个可有可无的东西了,反正出事了有保险。有了bumper spacer也不见得一定能起到什么作用,至少对于3箱车来说是这样。
