In just a few years, the quality of domestic cars has suddenly improved so much?

A few years ago, I recommended domestic cars to my friends, and their first reaction was surprise! Then a lot of questions will be thrown out, whether the domestic quality is good or not, and whether the fuel consumption is high or not. The summary is that domestic production is not good! In order to get rid of the label of poor quality, both third-party research institutions and professional market consulting companies have made great efforts. The data given by them all prove that the quality of domestic cars is above the industry average, and individual brands even surpass many established joint ventures to rank in the forefront of the industry.

Speaking of domestic production, it is estimated that some people will refute it! The domestic products here mainly refer to veterans of independent brands such as Great Wall, Chang 'an, Chery and Geely. Their history of building cars is only over 20 years. In the environment of scarce and saturated resources, independent brands not only survived, but also became the backbone of China. Today, the market share of independent brands has stabilized at around 37%.

Call the wind and rain?

In fact, the development law of the automobile industry is similar. When the per capita car ownership reaches a certain scale, the overall efficiency of the car will stop growing and remain in a stable range. China has only 173 cars per capita, while the United States has more than 800 cars, and even Korean cars are several times as many as ours. According to the forecast, the peak annual sales volume of domestic cars is 42 million. Who doesn't want a piece of this big cake?

At the same time, overseas parts suppliers have also increased their investment, such as Schaeffler, ZF and Chinese mainland. Even Toyota, which has always been cautious about expanding production capacity, has increased its holdings of Kelimei. A large number of foreign-funded enterprises have flooded into China, but their own brands have tasted the sweetness, and their own brands can finally enjoy the treatment of joint venture brands!

An ordinary car has more than 10000 parts, and the body harness is more than 1000 meters long. If any part goes wrong, a subsystem will be paralyzed! Anyone with a little common sense knows that it is unrealistic for an enterprise to produce tens of thousands of parts. Not long ago, the professor went to an engine factory of his own brand. At that time, the engine R&D engineer confidently introduced that the thermal efficiency of our new engine reached 37%, and the power and efficiency were equivalent to those of international first-line manufacturers. It is estimated that some people here will argue that the quality should be at the joint venture level first! What is the level of joint venture? Let's start with the details here.

In fact, big breakthroughs often start with small details. After some observation, I found that many joint ventures have technology, and all of this domestic engine has it! For example, the mirror technology of the intake valve of Honda Accord hybrid engine, the piston oil channel cooling of Mercedes-Benz M264, and the single turbine and double scroll of BMW.

Further study, you will find that valves, pistons, rocker arms and turbines are timing chains, and almost all parts are provided by suppliers. In other words, car manufacturers don't even make their own engines!

No car company in the world makes cars, but it is done by itself, and everyone needs the cooperation of suppliers from all industries, Qi Li. For example, Toyota's best engine, many designs need the help of suppliers. For example, laser cladding, a technology that makes Toyota applaud, is actually a scheme of a Swiss company. If independent brands also cooperate with this company, the same technology will also appear on domestic engines.

Automobile manufacturers can draw world-class drawings, but to turn them into products, suppliers need to solve problems in technology, materials and reliability. For another example, Mazda's latest HCCI engine has a key component called cylinder pressure sensor. Without it, you can't work stably. However, a sensor in the laboratory is worth 65,438+10,000 yuan, and the cost of installing four sensors in an engine has gone against the sky! Finally, Citizen designed a satisfactory part for Mazda, which enabled the new engine to be mass-produced.

In the past, domestic cars always had various minor problems, and the reasons behind them were actually very helpless. At that time, supporting resources were scarce and the price was extremely high. Everything had to be done by yourself. Now independent brands only need to concentrate on technology research and development, and suppliers of engineering problems will line up to provide solutions! As for who wins the flop, it depends. ......

The quality of domestic cars has been greatly improved. The main reason is that the automobile market in China is too big. Now, the sales of 28 million cars a year have almost accounted for one-third of the global share. Several independent brands sold millions of cars a year. For such a big customer, the supplier can't bear to watch it delivered to others. After all, Party A is the father! Today, China's automobile industry chain is perfect, not to mention self-production and self-marketing, even if it is sold domestically, it is completely feasible.

The second joint venture?

China's automobile market is a joint venture, supplemented by domestic production. Although there are different opinions on the joint venture model, from another perspective, foreign brands were not rejected because of the disparity in strength at home and abroad in the early stage. In the middle stage, we will learn automobile production technology through joint ventures, and in the later stage, we will expand our own brands with experience and capital. In short, the domestic car survived.

If you have been to the factory of your own brand, you will find that there are many similarities with the joint venture brand, such as their assembly technology, quality management or testing standards. The most important purpose of joint venture is to cultivate talents. Take the technology research and development center of SAIC Group as an example. Most people have worked in joint venture brands, and some management members have held important positions in joint ventures between Volkswagen and GM. Do you think there are fewer talents with independent brands?

Here, the professor tells another vivid story. During the transition from "National Five Plan" to "National Six Plan", the emission upgrading speed of many joint venture vehicles such as SAIC Volkswagen and SAIC General Motors was not as fast as that made in China. There is a simple reason. SAIC has given priority to Roewe and MG. When they completed the switching and listing of National 6 early, the national 6 engine of the joint venture brand was still lying on the bench!

Most independent brands have established joint ventures with overseas car companies, such as Chery Jaguar Land Rover, Great Wall Crossbeam Automobile (BMW) and Geely Volvo (Volvo Asia Pacific), and state-owned enterprises have also established joint ventures. The difference this time is that the two partners have their own strengths and needs. Independent brands are not satisfied with producing low-end cars, and hope to get involved in high-end manufacturing! So there are new brands, such as Wei, Xing Tu.

The emergence of independent high-end brands means that domestic cars have kept pace with luxury brands, and many details of products have the shadow of luxury brands. With higher premium capacity, domestic cars can get rid of cost constraints and arm domestic cars in turn with high-end automobile technology. Do you think the quality is good?

China standard?

Because it used to be a joint venture vehicle, vehicle development was generally completed abroad, and almost a plateau, cold, high temperature and high humidity experiment was completed in China. There are many problems to be solved, such as NEDC or WLTP cycle in Europe, but the driving environment in Europe is different from that in China, so that the fuel consumption of the Ministry of Industry and Information Technology is quite different from the actual fuel consumption.

America, Germany and Japan, as automobile powers, all have their own standards. With its own standards, corresponding test sites and data accumulation, this is precisely the weak link of its own brand! In order to make the reliability and performance of domestic cars reach the first-class level, China began to formulate China standards and build professional test sites. For example, China Automobile Research Institute not only undertakes the task of technical consultation and standard system, but also acts as a think tank! Want to know the level of joint venture car, China Automobile Research Institute provides one-stop service. In fact, the state funded the establishment of such a company, so that domestic cars can take fewer detours, which can be regarded as quality improvement!

Good cars are all tested, but you have to have a professional test site. Today, the hardware level of domestic automobile testing ground is already very high. The Turpan proving ground of SAIC Volkswagen, the Guangde proving ground of SAIC GM, and the comprehensive proving ground of Chongqing Changan Automobile are all world-class proving grounds. Anyway, there are various environmental proving grounds in China. The longer the test mileage, the more data accumulated, and the quality is based on these data. Many self-owned brands of prototype vehicles have a total mileage of 3 million kilometers, and some even reach 4 million kilometers. Is it not durable?

Professor summary?

The good quality of domestic cars is partly due to the influx of foreign parts giants into China, who brought a lot of technology. In addition to overseas giants, domestic auto parts suppliers are also on the rise. For example, domestic cars with a size of less than 654.38 million are almost all made in China, not because the domestic parts are cheap, but because of their good quality and performance. This year, it can't be said that the performance of domestic cars is not lost to the joint venture at all, but the quality of domestic cars around 654.38+ million will not be much worse than that of the joint venture. At present, the technical reserve of independent brands in high-end cars is still relatively weak, so everyone is scrambling to establish joint ventures with luxury brands.
