车的强度还是和重量(curb weight)有不少关系的,找到个证据

酸葡萄

this article is from edmunds.com,应该是比较权威的网站了. read following:

" {1 C& N' B- |/ H, V8 _2 UCompared to the previous-generation Lancer, the new car's wheelbase has been stretched 1.4 inches and the track has been widened 2.3 inches. Torsional rigidity has been increased an amazing 56 percent, while bending resistance has been improved 50 percent. Every detail of body structure, from the steering system's mounting points to basic structural design, was reviewed during development in an effort to maximize chassis integrity. For instance, the new Lancer repositioned the exhaust system to permit chassis cross members that are straight and strong.

最后一段说的很清楚了,as might be expected! 证明在正常情况下,(用超贵金属的不算啊) 好的设计可以增加结构强度,但重量也相应提高.当然不是越重越好,如果放个铁陀在车尾,重量是大,开起来也稳,但对整车结构强度没有任何帮助.

以前一个同胞所汽车强度只和结构有关，和钢板强度（一般厚的强度肯定大）没关，大概是自己开很薄的汽车的想自我安慰。我想那么用纸板做最好的结构岂不是最安全的？
