Japanese cars have thin iron sheets. Are their chassis and engines heavier than those in Europe and America?

In fact, the safety of the car itself has little to do with the iron sheet thickness of the car itself. You don't know the structure of the car, but it's a fable. In fact, almost all automobile manufacturers do not talk about the thickness of steel plate when promoting the safety of their products, but emphasize the body structure, because the structure and the distribution of the force after stress are the key to safety.

It is true that Japanese cars have thin iron sheets, but the weight of their peers is similar. LaVida car weight 12 10 kg, Corolla manual low allocation 1265 kg, cvt version 1285 kg, 1.2 version 1280 kg. Sylphy 1204 kg, Honda Civic 1243 kg, Lingpai 1275 kg. In contrast, Volkswagen is not heavier than Honda Corolla, so the weight of the thin iron car must be the weight of the chassis frame and engine. Therefore, the safety of the car has nothing to do with the thickness of the iron sheet. This decision is related to frame design and steel strength, as well as active safety and passive safety. Of course, in the end, it is most important for drivers to drive safely. The damage of the thin iron sheet to the impactor is weak at the point where it is seriously damaged in the middle and low speed impact. As for the thin iron sheet in high-speed impact, the same is true.

Japanese cars still have a layer of foam outside the anti-collision steel beam, in order to protect the people who were hit and not die because of small collisions. So most Japanese cars look embarrassed after being hit. In fact, they only hurt the shell and foam, which can reduce the impact on people and cars. Some cars have a thin layer of foam or no foam outside the anti-collision steel beam. Once they hit someone, it is equivalent to hitting someone with a hammer, and even a light touch may kill them.

Let's put it this way: in the case of conventional collision, that is, collision experiments, Japanese cars actually have the same level of protection for passengers as European and American cars, but in other cases, such as fireworks penetrating hackers' doors and killing drivers, Japanese cars are as thin as iron. As for Japanese cars that save fuel, I'll take the 2.4 old Odyssey, which also costs fuel. Crown 2.5 and Reiz 2.5 may not save fuel, but a. stepless speed change, etc. It is fuel-efficient, but the level of fuel-saving is not obvious compared with the current European and American cars. Chassis, well, let alone the chassis of Japanese cars. To tell you a joke, a colleague of mine has always said that his hacker is the strongest in the chassis, and everything else is average.
