Why are Japanese cars so crashworthy compared with German cars?

Why are Japanese cars so crashworthy compared with German cars? Judging from the photos of the car accident, the minor collision was caused by the serious deformation and falling apart of Japanese cars. In fact, judging from the collision results given, Japanese is not bad. What is the reason for its serious deformation?

First of all, the task of the body in the event of a car accident,

The car body was hit first in the car accident. We have never heard that the car body is intact and the engine is hit, or the seat is hit. The first to be hit are four doors, the front hatch cover and trunk, or the side body. These parts are equipped with anti-collision guards when the vehicle is still white, and the hardness is actually very good. In addition, the overall hardness of vehicle electrophoresis will increase, so it should be more crash-resistant, but the performance of Japanese cars is not satisfactory. The fundamental reason is that the sheet metal performance of body-in-white is not excellent enough.

The characteristics of Japanese cars,

Japanese cars are famous for their stability, and Japanese cars are also made by businessmen. It is not surprising that the Japanese are smart enough to wring out the last drop of towel. A nut can save money, so it is not surprising that frame materials are saved. What's more, none of the models with large-scale recall problems are due to sheet metal recall.

Collision experiment, as we all know, collision experiment is a must for every car. Japanese cars performed surprisingly well in the crash experiment. I think as long as the experiment is an exam, it is actually a trick. We can see that the most important thing is what the humanoid doll in the cab looks like, whether it is a frontal collision or a side collision experiment. How about a taxi? The frame of the Japanese car will be perfectly folded, protecting the cab as much as possible, regardless of the deformation degree of the whole car. Japanese cars have also mastered this principle, so they can get high marks in the collision experiment.

But real life is not a collision experiment, and real car accidents will not collide according to the set route. Therefore, the performance of Japanese cars in reality is very general.

The final conclusion: In any case, Japanese cars have their own unique car enterprise culture, and the effective collapse in the collision will really protect the cab, but the thrilling deformation degree really makes consumers sweat. I hope that Japanese cars will be improved in body sheet metal, so that consumers can be practical.
