A winter test detonated the car rim, and it is estimated that no one expected that a mediocre endurance test would cause such a long chain reaction. The siege of car companies is rareIt is rare to be able to let so many car companies point the finger at a ** evaluation, which is rare in so many years of development, after all, in the domestic automobile circle, there have been various ambiguities between car companies and ** for a long time, and it is also a daily operation to create "high points" for each other, and it is still a rare thing to tear the face so directly in this atmosphere. 
On December 6th, the understanding car emperor announced the results of the winter test, among which in the test of "plug-in hybrid group, unified WLTC standard pure electric range achievement rate", the endurance achievement rate of the M7 Zengcheng version ranked at the bottom, only 316%, in the face of such a dazzling data, Yu Chengdong couldn't sit still. 
The test of the pit people, mislead the people!Science and rigor are the basic rules that should be followed!The sharpness of the wording is in line with Yu's big-mouthed style, and it also shows the extreme dissatisfaction with the review, which believes that the vehicle was heated by air conditioning for a total of 71 minutes before the official test, and after the temperature inside the car reached 24 degrees Celsius, it continued to heat for another 40 minutes. In this process, there are more than 10 operations to open and close the doors and windows, of which the longest time is more than 3 minutes, which greatly increases the energy consumption, resulting in a rapid decline in power, which deviates from the user's real use scenario. 
Next is the Great Wall, with Weibei Gaoshan DHT-PHEV, Wei Lanshan DHT-PHEV and Haval Raptors respectively. 78% and 35The 83% achievement rate ranked first in this test.
VI. 8. Twelfth, the reason for the dissatisfaction is similar to the point of view put forward by the questioning world, and the Great Wall announced to the public that it is "tough".Breaking the news?Revealing the truth?If you dry it, you have to see the Great Wall", and announced the opening of the new energy test platform in the communication meeting on December 14. 
On the day of the communication meeting, Mu Feng, President of Great Wall Motors, said on Weibo: "The new energy environment testing capability built by Great Wall Motors is now open to the whole industry to provide more rigorous, fair and objective product testing. "This includes the opening of the new energy test platform, the opening of the Heihe winter test center, and all its new energy test equipment, as well as the provision of summer test equipment and test suggestions for the first class. 
Geely also participated in the controversy, Yang Xueliang publicly said on Weibo: "I also think that the evaluation process is unscientific, not rigorous, and the conclusions are not convincing, which not only misleads consumers, but also hurts the credibility of Chedi itself." ”
In this regard, the company also made an official response, saying that all projects in the 2023 Winter Test use unified test standards, which are in line with the user's use of cars in the extremely cold environment in winter, and there is no discrimination, and on the morning of the communication meeting held by Great Wall Motors, the winter test open day was held, and the car companies were invited to observe on the spot, and some online self-reports on this matter were held accountable. What do you think of the **review?Not for this winter test of the car emperor, only from the perspective of ** evaluation will actually cause some thinking. Now there are two points with relatively high traffic on the vertical platform of the car, either the beauty appears, or the comparative evaluation of multiple cars, one is to pull the best amount at the visual level, and the other is to bring out the topic through the competition between competing products. And we are now seeing more and more types of reviews, traditional, nonsensical, and scenario-based, basically varied, only unexpected, nothing can be done. 
Why do consumers love to watch comparative reviews?At this time, we must first answer the question, is the reliability of the official data higher or the evaluation data given by a third party is more credible?From the consumer's point of view, it is very easy to answer, I believe that most people will be inclined to the latter, and it is also easy to understand that the official data given by car companies is like Lao Wang selling melons and boasting, who will give some negative data when promoting their own products?This is also the fundamental reason for the birth of ** evaluation, people's subconscious will be more convinced of the information given by the third party, just like to find the appraisal themselves, the decoration to find the supervision, etc., I hope that professionals familiar with the industry will give some more professional evaluations and appraisals. Especially in the current new energy era, compared with the era of internal combustion engines, the most critical core element of the product has attracted everyone's attention, coupled with the characteristics of new energy vehicles, some "" congenital defects of power batteries, and low-temperature battery life This is also one of the pain points that have always existed in the industry, so consumers want to see what kind of actual performance the product can have in the real environment. Then it's time to pay attention to whether this so-called "professional evaluation" can be called professional. The evaluation is a set of systematic tests, and it is also a very rigorous test with a standardized process, so does the evaluation meet these requirements?It can be difficult, and most of them stay at the level of entertainment. No matter how big the battle is, compared with professional testing, there is a considerable gap in many aspects such as personnel professionalism, equipment and instrument accuracy, rationality of scene planning, fairness of test environment, test budget, etc., which is also one of the reasons why many car companies are dissatisfied with some evaluation results. 
In fact, not only the car companies are dissatisfied, but even the mass consumption has raised questions about some of the tests in the industry now, taking the battery life test as an example, the details of the power before departure, the test environment, and the test process have not been announced to the public, and then the key information of the vehicle that participated in the test, the mileage before the test, and the battery life of the vehicle itself does not seem to be strictly unified. So now this logic is very clear, the national standard is there, but not according to the national standard test, although in their own environment to achieve the so-called extreme, the test results are still inaccurate for car companies, and this evaluation has also had an impact on the reputation of car companies, misleading the public, naturally can not be accepted, so look at it, some of the so-called preset standardized scenarios are not as practical as putting them into the actual car scene to test. Really review or earn traffic?**What is the final result of the review?This may be the crux of the problem, after all, the car companies sell more or less cars will not have a great impact on the first, and there is no direct benefit deliveryNature is a topic, a car with a topic, a brand with a topic, and these together will also amplify the topic infinitely. 
In this environment, whoever has traffic basically has everything, and follow-up cooperation will follow. On this issue, on December 12, there was also a winter test list on the Internet that was suspected of understanding Chedi, which showed the rights and interests of "independent brand" and "luxury joint venture brand", of which the winter test driving fun version in the column of independent brand was directly 16 million yuan. As soon as this picture came out, it ignited the heat of this incident even more, and it was still emphasizing fairness and justice, and there was no differentiated treatment, although some people who understood the car emperor said that none of the 53 cars in the winter test had commercial cooperation, and no car company could interfere with the test and affect the test results, but the authenticity of this picture was not denied. 
For the current domestic automobile industry, the current credibility is not high, as mentioned earlier, the rapid development of China's automobile market in just a few decades has formed a tacit understanding between car companies and **, and even said that the overall environment is now lacking some real voices, this status quo for the subsequent development of the hidden danger is obviously buried. Finally, back to the matter of evaluation, from the perspective of consumers, there needs to be some judgment on the content of the evaluation, although it sounds nonsense to let consumers make their own judgments, but this is the reality of this industry;In addition, from the perspective of car companies and enterprises, for new energy, which has developed rapidly in a short period of time and is clearly the main path of subsequent development, it is necessary to unify a standard, which is responsible for consumers and is also a moral and technical constraint on itself. 【idailycar】
