车的强度还是和重量(curb weight)有不少关系的,找到个证据

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

Compared 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.

Heavily updated
As might be expected, this increase in the strength of the Lancer's chassis adds to the car's curb weight. Depending on trim level, the new car is approximately 200 pounds heavier than the previous-generation Lancer.

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？
