The Germans invented the car, and the Americans invented the assembly line of the car platform. But why is the quality of the Japanese car better? Is it true that only the Japanese pay the highest quality? Is the quality of the car produced in the Japanese factory better than other brands? ?

Here we must say that any responsible car brand, especially those who value their own brand value, attach great importance to product quality. In today's highly developed information, no one dares to take the world by big trouble. The rate spread. Like the Pinto car in the 1970s, in order to save the cost of 11 dollars, the development defects of the consumer at the expense of life, without correction. But this is only a category of development defects. In the quality of product manufacturing itself, there is no enterprise that does not do everything it can to reduce the failure rate.
In this way, all car brands should have sufficient quality assurance, what is the difference in failure rate?
The technical level of the car company is on the one hand, technology is the ability to guarantee the problem of solving the problem, but this is not the most important. Obviously, many of the century-old car brands, car brands with high enough manufacturing process, have higher failure rates than Japanese cars with civilian prices. It is said that the Japanese do things rigorously, so the quality of Japanese products is guaranteed, but the people who do things rigorously have Germanic, are there no quality guarantees for the products they produce?
The fault is not in the rigor of the manufacturing process. In fact, there are two general reasons for the failure of the car, one is the use of faults, and the other is the development of defects. The use of faults includes the use environment and age; development defects include all aspects.
The use of faults is better understood, and development flaws sound great, and terrible, because failures are probable, and development flaws seem inevitable. But it is not, because products that are on the same line often fail from development defects. This development defect does not generally fail, because the so-called development defects are adaptive to environmental changes.
Many military fans know that an aircraft has been developed and tested under extreme conditions such as wind tunnel tests, static pressure tests, and extreme cold tests. The same is true for cars. From the Dakar Rally, Formula One, to the ice and snow test drive made by some brands, it seems to be in public relations hype, branding, in fact, the first is to do the limit test. Even so, the development of each product can not adapt to the different needs of the global environment.
As a well-known example, dual-clutch transmission and direct fuel injection technology are indeed leading and mature technologies, but why do dual-clutch transmissions fail frequently in China, and fuel direct injection technology does not show fuel-saving effects in China? Don't blame the manufacturers who provide this technology. There is no problem with the quality of their products. Even the technology is mature technology, and there is no development defect in the general sense.
Yes, it can only be said that there is no defect in the general sense, because the elimination of development defects is subject to the premise, that is, in what environment. The use environment of the dual clutch transmission is afraid of overheating, and the direct injection technology in the cylinder is developed for high speed driving. Therefore, in the congested driving environment of China, the dual clutch transmission frequently shifts gears, which is easy to overheat and protect, causing the work to stop. While the in-cylinder direct injection technology is used in a congested environment, it will not burn enough, resulting in oil consumption. However, Chinese people's understanding of technology comes more from the introduction of concepts. As long as it is advanced in concept, it is suitable for unsuitable, so manufacturers have to cater to the psychological needs of Chinese consumers and are forced to adopt "advanced technology". Causes poor results or even increased failure rates. The cause of this failure is that the local development is not thorough enough.
What is the local development? The mystery is constantly being solved. The reason for the low failure rate of Japanese cars is actually very simple, that is, local development. For example, in Southeast Asia, do you like Toyota cars? This problem may seem to be brand inertia today, just like most Chinese people are predecessors like German cars. But how did Toyota get into the Southeast Asian market at the beginning?
It is necessary to know that Southeast Asia is a free market. There are not many barriers to entry, and it is the only way for shipping. Therefore, there is no question about which brands are not valued, causing Japanese cars to occupy the market. The real reason is one, and it is a particularly small reason - air conditioning and cooling. Yes, Southeast Asia is located in the tropics. The cooling demand for air conditioners is higher than many technology configurations. The Japanese cars represented by Toyota have seized this feature and worked hard on air conditioning and refrigeration, so they seized this opportunity. .
On the one hand, the European and American cars are platform-oriented, and the products around the world pursue the same development. On the other hand, because of the long history of car construction, self-confidence and self-confidence, the lack of local development and revision. Therefore, it will appear that the use of good dual clutch and traditional in-cylinder direct injection technology on the speed limit highway in Germany is also used in China. The use of good engines in smooth traffic in Europe is also on the Chinese roads that stop and go. The result is that high-tech, which is based on energy conservation and efficiency, has improved the high-tech failure rate on Chinese roads. Fuel economy has dropped.
Toyota's local development method and Toyota and other Japanese cars do not choose this method, their purpose is very clear, that is, the application of any technology can not be used to limit the user's conditions of use. The first Toyota car, which has maintained the automotive technology patent industry for many years, has quite advanced technology in engine gearbox technology. However, Toyota believes that automotive products are a whole service for users, not a platform for sci-tech. Therefore, when many brands in China have adopted the "in-cylinder direct injection" technology, Toyota still uses the "manifold multi-point EFI" technology, which seems to be backward in technology, but the fuel-saving effect is still Toyota's lead. More importantly, the most advanced fuel injection technology and gearbox technology patents are still in the hands of Toyota.
Another example is why Japanese off-road vehicles are used in remote areas such as mountains and frontiers in China, including military vehicles. The reason is not complicated, because the use environment in remote areas is even worse. Unpredictable oils, thin air, rough road conditions, and durable off-road vehicles are the first choice in these areas. Consumers who are accustomed to urban standards are more concerned with the "up power" and "compression ratio" of the engine. They believe that the higher the power and compression ratio, the better the engine, but once they leave the city, these two standards It became the root of the failure. The higher the compression ratio, the higher the oil requirements and the higher the oxygen content of the air. Therefore, Japanese cars that deliberately choose low compression ratio and low power engines have more viability than other systems in that environment.
On the other hand, most people only look at the number of transmission shifts, but there is no data to prove that the same displacement models are compared, the multi-position products are less than the gears. The car is fuel efficient. If the station is in exchange for the maximum fuel economy at the lowest cost, the lower the gear position, the lower the gearbox failure rate. However, when the market voice strongly demanded “upgradeâ€, the Japanese car chose a more energy-efficient gearbox solution.
The survey data shows that the Chinese people need to feel the driving feeling of “pushing back†and pay special attention to fuel consumption. At the same time, with the spread of urban congestion, manual gear can no longer exist as a solution. The AT automatic transmission can solve the push back feeling, but it can not solve the fuel saving demand. If the high-speed automatic transmission is launched, the failure probability and maintenance cost will also increase. If the CVT continuously variable transmission is used, the problem of fuel saving and low maintenance cost can be solved. However, since the working principle of the CVT has no gear meshing mechanism, the power loss caused by the shifting is eliminated, and the torque bearing capability is also reduced. So lost the push back.
In view of this, the local development concept has played a role, Toyota has recently developed a geared S-CVT gearbox, which not only maintains the shifting power loss of the continuously variable transmission, but also increases the torque caused by the gear meshing. Endurance. At the same time, it satisfies the contradictory needs of the Chinese people for “pushing back†and “fuel savingâ€.
Future localization Localization development is not only found in the Chinese market, but Toyota and Japanese cars have the concept of local development and come from successful experiences in the US market. The German car lost in the US market and came from the stubbornness of its own development philosophy. The success of Japanese brands in the United States is precisely because of their localized development in the US market, and even the entire R&D institution brand name is newly laid out due to the US market.
Many people in China believe that foreign good technology must be copied to China, otherwise it will discriminate against Chinese consumers. From a commercial point of view, it is not excluded that the cost and the maximum commercial benefit are the trade-offs of product configuration, but from the perspective of reducing the failure rate and improving the efficiency of use, local development is the source of product differentiation in the leading region.
In the future, as Japanese brands pay more attention to the Chinese market, there will be more localized development products, and even the possibility of localizing Japanese brands in the Chinese market (similar to Japanese luxury brands in the United States) will not be ruled out. The Chinese car consumer groups will gradually shift from concept demand to result demand. The successful experience of Japanese cars in the US and Southeast Asia will also be replicated in the Chinese market.
