The current automobile safety concept adopts the collapse mode. Simply put, this mode means that during the design process, a large amount of hot-formed steel or high-strength steel is used for the cab parts that require strict protection. For wrapping, the material used for the crumple zone at the front of the car body should be relatively softer. The purpose of this design is to use the cushion of the material during a collision to buffer the stress generated by the collision, thereby achieving the purpose of protecting the members in the cab. .

It is important to note that currently, due to factors such as materials and costs, the collapse concept is only applicable to speeds below 64 kilometers per hour. That is to say, once the car's speed exceeds 64 kilometers per hour, Kilometers, the crumple zone method cannot absorb the stress generated during a collision, so there is still a risk of the cab deforming.

Generally speaking, whether it is the iihs in the United States or the E-CNAP crash test in the European Union, the performance of Japanese cars is remarkable. Except for the smallest individual models, due to the helmet lock space It is really limited, coupled with cost constraints, and the results of the crash test are not ideal, overall, the crash results of Japanese models are guaranteed. Many friends may say that this kind of crash test is actually a test-oriented design. However, in the test process of this kind of medium and low-speed rigid design test, there are still many models that cannot meet the passing standard, and they are expected to be able to survive a high-speed collision. Does it work?

Of course, many models will have various simplified configurations when they arrive in China, and Japanese cars are no exception. However, relatively speaking, the extent of this reduction is not too large. Some models even have different configurations when colliding with foreign models. The results are almost the same. For example, in the domestic crash test conducted by China Insurance Research Institute, the scores of Chinese and Japanese cars were both good and above. On the other hand, in other car series, there were even cases where the A draw one area was forced to break.

Generally speaking, Little Japan is still very shrewd in cost control. All designs are usable and sufficient. From this perspective, the car body sheet metal is indeed very thin, especially very soft. The so-called sense of luxury and class are not related at all. From the perspective of chassis texture, most Japanese cars use relatively cheap impact parts in the chassis, which gives people a loose feeling during driving. Of course, this There is no problem with this cheap impact arrow in terms of safety. Judging from market feedback, Japanese cars basically have no problem with shaft breakage. But why do many domestic car enthusiasts prefer Japanese cars?

From a performance perspective, Japanese cars are not compatible with performance cars at all. Since naturally aspirated engines and Cvt gearboxes were used in large quantities in the early days, this matching is more about daily driving. stability and ride comfort. Relatively speaking, Japanese engines are relatively reliable in terms of durability in long-term use. Leakage and oil leakage rarely occur, even if Japanese engines have entered the turbocharger system. Era, relatively speaking, is still slightly better in terms of quality control and stability. Of course, some car enthusiasts may say that Honda's engine oil increases and Toyota's engine oil is emulsified. Isn't this a shortcoming? This is of course a shortcoming, but it is mainly a problem of engine design and has nothing to do with engine manufacturing and durability.
