扭转刚度是汽车的关键参数，用以衡量将车身框架扭转1度需要施加多少力。数值当然是越大越好。
以消费者的角度看，高扭转刚度车身的好处是什么？
在过弯时，它让你觉得“牢靠”，尤其是地面凹凸不平的时候。当车身受到悬挂传来的外力，它扭转的程度更小，因此车舱感受到的异响和晃动也会相对更小。
因为有这些好处，豪华车和运动车往往具备更高的扭转刚度。
不幸的是，许多制造商不会公布这些数据，即便他们的产品本身扭转刚度非常好。有些制造商会公布这些数据，但并不宣扬，或以此作为卖点。
数据来源都有据可查。比如欧美汽车工业传媒公布的信息（motortrend，car and driver等）；或者工业协会文件（例如SMDI，SAE等）；或者汽车制造商的个人采访。有些数据是根据多方信息推导而来，并不保证100%正确。
