Jin Yuankun looked at Li Zhongxin, and he frowned slightly. After thinking about what Li Zhongxin looked like, he slowly spoke: "When I was in China Automobile Group, I was engaged in laboratory work for automotive parts and vehicle testing, and I have experienced a lot of test and verification of automotive parts, so I will talk about the difference between domestic cars, joint venture cars and imported cars in the car design and development stage.

There is something called a system platform for automotive R&D and production. In fact, automotive R&D engineers design parts based on the system and verify through experiments that the designed parts meet the requirements of the system standards.

Classic European, American and Japanese models have mature system standards, and the design effect has been verified through years of experience.

Domestic car manufacturers have been working with joint ventures for so many years and know the standards, but they don’t know why the standards are designed in this way. What impact will change a certain design have?

I mean that domestic car manufacturers only understand the system design standards of some mature joint venture models in the domestic market. There is no other meaning, just to understand the standards, and the system contains too much content.

At present, joint venture manufacturers generally have their own brands, which is the domestic cars we are discussing today. Joint venture cars in joint venture factories are basically designed according to standards, and each part is basically verified according to the corresponding experiment. If it passes the experimental verification, even if it is unqualified, it is necessary to find a raw material supplier to re-provide the parts that meet the requirements.

Some of the old-fashioned cars of foreign brands have become distorted when they arrive in China. Due to cost reduction or the strong domestic joint ventures, some product verifications sometimes result in compromise conditions such as cost pressure.

For example, to verify the light-resistant performance of a plastic piece, the original standard requires 1,000 hours in the experimental state.

As a result, the sample will fail within 800 hours. If you want to improve it, the manufacturing cost of the sample modification will be doubled or even several times. Under cost pressure, the OEM may think it is acceptable for 800 hours, and the item will be left alone.

Because of the pursuit of profits, the reduction of standards and distribution of joint venture materials for vehicles is a common situation. The crux of domestic cars lies in money.

Domestic cars basically do not have their own completely independent standard system. The system standards that are copied from the east and the west are copied from the east and the copied one machine factory copying the standards of several host machines. The system standards of foreign manufacturers are mature systems that have been verified for decades and hundreds of years. Domestic cars are copied from the likes of this lack of scientific design basis.

Someone asked, don’t you all know the standards for joint venture cars? You can just follow the original standards. However, there are too many subsequent things, taxes, suppliers, repair shops, model design companies, and advertisers all need to spend a lot of money.

Some foreign automobile companies have more than hundreds of millions of dollars in seat design costs, which is just a design cost for design companies.

If our domestic companies want to create a seat design, can they spend so much money? The poor sales base is destined not to invest too much.

There is also the system difference. The verification level of some domestic cars here is constantly downgraded, and they even do not even verify it. The raw materials are right and can be loaded directly for vehicles. The same plastic parts joint venture car must pass 1,000 hours of high temperature exposure according to the standard, and domestic cars can be directly 300 hours. Qualified and loaded.

Many companies have their own models, except for the national forced inspection experiment, and do not do other tests if they can be done. Otherwise, suppliers will do it themselves and produce it themselves to verify it themselves. Isn’t this a joke, and they will also be judged as unqualified?

If you can't do it yourself, you will find the type of company you are in, which one is cheaper, and there are many third-party testing institutions, and there are often cases of experiments and suppliers doing fakes.

The most intuitive impression of people using domestic cars is that the main parts of the car are rarely broken (the core parts such as the engine are foreign brands), but there are many small problems. The plastic cracks today, and the door lock will break tomorrow, so it’s okay to open it.

This is the current situation of our domestic cars. Compared with our domestic cars, imported cars have much greater advantages. The mainframes, including engines, etc. are produced by the original manufacturer themselves. All other accessories meet the standards set by their country or the world. It is difficult to think it is better than domestic cars in China.

Also, among our country's joint venture automobile factories, only the two types of cars produced by Zhongxin Company and Volkswagen in Shanghai are of better quality. The quality of several new joint venture automobiles that have been launched recently is much worse. They mainly make money for money, and do not consider quality or many aspects at all." Jin Yuankun slowly spoke to Li Zhongxin while drinking tea.

"Oh, Mr. Jin said it very well. The current gap between domestic cars and foreign cars is basically clear at a glance. What is the difference between joint venture cars and imported cars? After all, joint venture cars are basically imported from foreign countries, and all kinds of technology and other things are also foreign?" Li Zhongxin thought for a moment and asked slowly.

"Domestic joint venture cars and pure imported cars are two concepts. Any model will be redesigned and loaded in China. There will be many changes in order to reduce costs.

For example, the standard ESPs abroad do not have this requirement in China, because Chinese passenger cars do not have this requirement, and any car must meet the corresponding national standards when it is launched.

But our country does not have such a standard requirement. What will manufacturers pursuing profits do?

Speaking of this, there is also the voc in the car, which refers to all non-metal parts in the car that volatile harmful gases. This is closely related to passengers and drivers. The air breathed in the car all year round will affect health. Each car manufacturer has a control value. To achieve the qualified value, it must have requirements for the raw materials and process usage of all components in the car.

However, so far, the country has only recommended standards and no mandatory standards. Moreover, this recommendation standard is basically lower than the standards owned by foreign car manufacturers. Joint ventures can reduce costs without using their own VOC standards. It is enough to meet the national recommended standards. It is necessary to control the VOC value and involve all non-metal parts of the carriage. A little reduction can save a lot of money. That is, Zhongxin Company and Volkswagen in the Shanghai Stock Exchange are doing a good job in this place, so there is also a big difference between domestic joint venture cars and foreign imported cars.

This is just my personal opinion and thoughts, and it does not mean that all Chinese auto manufacturers are like this. Our country's automobile development still has a long way to go." Jin Yuankun couldn't help but sigh at the end.
