Recently, the rims are once again "lively" because they understand the winter test of Chedi in 2023, and the results of the winter test in 2023 released by them have caused many car companies such as Huawei, Great Wall and Geely to openly question. Yu Chengdong, chairman of BU, Huawei’s smart car solution, and Yang Xueliang, senior vice president of Geely Holding Group, are all publicly "angry", and Great Wall Motor has publicly voiced that it will hold a "communication meeting to understand the winter test standards of Chedi" to explain the new energy winter test standards to users; At the same time, some manufacturers have made a lot of publicity, such as BYD ACC test and the endurance of Link 08. On the one hand, it is questioned by many big names, and on the other hand, it is sought after by many manufacturers. How can it be controversial to understand the winter test of Che Di?
Controversial media of winter car testing enterprises will not give way to each other.
In view of the results announced by Chedi Winter Test in 2023, the core of controversy among major manufacturers lies in whether Chedi’s test method is scientific and fair, and whether the test results are accurate. For example, in the endurance test, the pure electric endurance achievement rate of hybrid vehicles under severe cold conditions was tested, and about 20 vehicles participated in the test. Among them, BYD ranked first with 85.08% endurance achievement rate, and the extended-range version ranked last with 31.6% endurance achievement rate. Huawei, Geely and Great Wall Motor believe that there are irregular operations in the test process, such as abnormal heating and frequent opening and closing of doors and windows, which may affect the accuracy of the test results.
Yu Chengdong, chairman of BU, Huawei’s smart car solution, said on social media: "cheat people’s testing, science and rigor are the basic principles that should be followed". Yang Xueliang, vice president of Geely Automobile, also said: "I also think that the evaluation process is unscientific and rigorous, and the conclusion is unconvincing, which not only misleads consumers, but also hurts the credibility of knowing the car." The official blog of Great Wall Motor also announced that "if you fish dry, you have to look at the Great Wall", and a "communication meeting on understanding the winter test standards of Chedi" will be held to explain the standards of new energy winter test to the public.
In the face of major manufacturers’ disputes, Knowing Car Emperor also made an official response. Knowing the car emperor said, "In 2023, knowing the car emperor’s winter test, all projects use unified test standards, which is in line with the user’s extremely cold environment in winter, and there is no differential treatment. At present, the winter test of Knowing Car Emperor is in progress, and Knowing Car Emperor will hold the 2023 Winter Test Open Day in Mohe, and invite all participating car companies to observe on the spot. "
Since then, Knowing Car Emperor has conducted another live measurement of the highly controversial extended-range/plug-in pure electric vehicles, and some car companies, media and user representatives have been invited to experience supervision on the spot, aiming to show objectivity and fairness.
Is the winter test meaningful? Spending manpower and material resources is worthless?
Winter test is a test of vehicle performance in cold environment, simulating various extreme conditions that vehicles may encounter in actual operation in winter, so as to test vehicle performance, which is also a necessary action for various car companies when developing new cars. Knowing about Chedi’s winter test has triggered a scuffle of online public opinion. Under the chaos, can we get some valuable results from it?
Looking at the problem from the details, there may be some imprecise operations, or the variables are difficult to control. However, aside from the network controversy of the winter test, in fact, from the whole test results, there are still places worth exploring, and we can also get a glimpse of the overall development of the industry.
This time, more than 40 brands and 51 new models participated in the winter test, including established China brands (such as BYD, Geely, Changan, etc.), new car-making forces in China (Weilai, Ideality, Tucki, Gaohe, etc.), established car companies in China, overseas luxury brands (Mercedes-Benz, BMW, Audi, Tesla, etc.), overseas mainstream brands (Volkswagen, Toyota, etc.).
Judging from the test that has been completed at present, it is not difficult to find that the overseas brands that once "hanged" the China brand have now been rubbed by the China brand.
First of all, none of the overseas brands passed the first round of elimination in the ACC braking test. On the other hand, eight models of China brand were successfully promoted, among which four models, U8, Weilai ET7, Tengshi N7 and 11, were successfully passed in the 40km/h night backlight scene ACC braking. It can be seen that China automobile brands are in the forefront with absolute advantages, and they have sufficient confidence in technology.
In the low-temperature charging test list, China brand still occupies the leading role. The top five in the list are Aouita 11, Zhiji LS6, Haobo GT and Audi RS e-tron, among which the top four are China brand models. From the price point of view, the fifth-ranked Audi RS e-tron has exceeded one million, while the most expensive of other higher-ranked China brands is no more than 400,000 yuan. As an important test to test the performance of battery system, it is not difficult to see that China brand cars have established advantages in core technology. At present, the single test of smart car has not been carried out, but judging from the continuous deep cultivation of China Auto in intelligent technology, the final winner is self-evident.
The winter climbing project is a big test for vehicle control. Recently, the sudden snowstorm in the north has caused many traffic accidents, and it has also raised people’s concern about driving in ice and snow. Snow climbing can be said to be a comprehensive test of vehicle power, electronic body stability system, chassis, braking and other performance.
If ACC braking tests the intelligence level of the vehicle, then ice and snow climbing is definitely a test of the underlying hard power of the vehicle. China brand cars have also been proved by actual performance, which is not only intelligent, but also hard in handling. The first and second place of this project were won by Equation Leopard 5 owned by BYD and Tank 400 Hi4-T owned by Great Wall, and their climbing slopes reached an exaggerated 62% and 60%. It is worthy of praise that Geely’s smart Elf 3 has also achieved 40% climbing performance, comparable to the hard-core off-road vehicle warrior 917.
The results of other vehicles are mainly concentrated between 29% and 34%, among which the showdown between Haval Raptors and Cadillac IQ Ruige and the showdown between Gaohe HiPhi Y and Mercedes-Benz EQE SUV can be said to be the representatives of China brand versus overseas brands. Judging from the results, the Haval Raptors with lower prices have won the Cadillac IQ sharp song. In the contest between HiPhi Y and Mercedes-Benz EQE SUV 500 4MATIC, Mercedes-Benz EQE SUV 500 4MATIC won by 2% with high torque. From the video point of view, HiPhi Y is based on high-performance electric drive, CIC integrated chassis control and CDC continuous variable damping shock absorber, and its climbing trajectory is very stable, and it finally achieves the maximum gradient of 34%, ranking second in pure electric medium and large SUVs and tied for first in China brand pure electric medium and large SUVs.
Finally, the winter endurance test has always been the most concerned topic for new energy users. Previously, I knew that the public opinion war between car owners and car companies was mainly focused on plug-in/extended pure electric cruising range. In the battery life list of pure electric vehicles, although the top three are still unknown, it is not difficult to infer from the participating vehicles and the published results. The top three are ranked among Aouita 11, Gaohe HiPhi Y and Zhiji LS6.
Understand that the warm-up video of the car emperor reveals that the pure electric SUV with the longest cruising range is 420km. At present, the discount rate of the fourth place is about 5.3 fold. It may be calculated by 5.5 fold. The standard cruising range of the vehicle is estimated to be about 760km. From the selected models, the high probability is high Hip Hi Y. This is mainly due to the 115-degree super battery carried by HIHIY. If it is a long-life version driven by a single motor, the cruising range is as high as 810km. At the beginning of its listing in July this year, it also refreshed the cruising record of mass-produced pure electric SUVs.
At present, the discount rate of the car with the first endurance in winter test is 60%. From the video screenshots, the probability of the blurred dashboard is Aouita 11, and the battery carried by Aouita 11 is also not small, even 1 degree higher than that of Gaohe HiPhi Y, reaching 116 degrees, but the CLTC endurance is 700km, which is slightly weaker. If you look at the standard battery life of 700km, the final result should be comparable to Hip Hi Y.
After inferring two cars in the top three, the only remaining model is the Zhiji LS6. Since the launch of the Chengdu Auto Show, it can be said that the price/performance ratio is full, which directly steals the limelight of Tucki G6.
We put aside the rigor and fairness of Chedi’s evaluation for the time being. It is not difficult to see from the total score list that China brand has completely surpassed overseas brands in the new energy era, and we don’t comment on individual achievements, but from the overall trend, it is not difficult to see that China brand cars have achieved a real rise, which is worthy of praise!
Two days ago, the former Top Gear host Three Musketeers announced that they would stop The Grand Tour, which was later created. Fans lamented that the best car show in the world had disappeared. In 2012, Top Gear made a special issue of China, which was in the embryonic stage of China’s new energy vehicles, and the policy of supporting the new energy automobile industry in China had just begun. The entire China automobile market was still dominated by joint venture brands, and the China brand was labeled as "cottage", "low price" and "inferior quality". Ten years have passed quickly. Now, looking at the China automobile market, it has already been the world of China brand. BYD and Geely in the old car companies, Wei Xiaoli and Gao He in the new forces, etc., have opened up overseas markets one after another and won the respect of overseas users.
Ending:The great discussion caused by the 2023 winter test of Chedi is an industry debate on whether the test method is scientific and fair and whether the test results are accurate. No matter what the final result of the debate is, it is undeniable that a test or a media must be objective, fair and rigorous if it wants to have credibility. From the perspective of car companies, it is necessary to constantly improve technology and enhance the strength of products.
