Tesla will open the FSD patent, and the free one is the most expensive?

There is a free lunch in the world. Can you believe it?

Recently, Tesla CEO Musk said: "Tesla hopes to help other auto companies as much as possible … We are also very happy.License Autopilot /FSD or other Tesla technologies to companies in need.. "

As Tesla’s signature technology, FSD, if the patent is open, it is quite a pie in the sky for friends.

The spirit of "selfless dedication" also made domestic netizens shout: "Why can’t there be a person like Musk in China?"

However, don’t rush to worship, it’s not that simple behind Musk’s opening of FSD.Free may be the most expensive..

Tesla’s self-driving products can be divided into three categories: BAP (basic version of automatic assisted driving), EAP (enhanced version of automatic assisted driving) and FSD(Full Self-Driving Computer). Among them, FSD has the highest grade, and it needs to spend an extra 64 thousand yuan to choose and install.

It is worth noting that FSD is not really fully autonomous driving.

According to the classification of SAE (American Society of Automotive Engineers), there are 6 levels of autonomous driving, including L0-L5. According to this standard, FSD still belongs to L2 level.

Musk has repeatedly stressed that the FSD needs the driver to be ready to take over the vehicle at any time, and the steering wheel cannot be separated from his hands, so the FSD has not reached L3 level. But in fact, some functions of FSD have surpassed L3 and L4.

From the technical route, Tesla is a fan of the pure visual route. Since February 2022, millimeter-wave radar has been cancelled on all North American models.

Most mainstream car companies adopt multi-sensor fusion solutions, including "Wei Xiaoli", BYD and Volkswagen. The purely visual route is relatively small. In addition to Tesla, there are now manufacturers such as Toyota and Baidu Apollo to follow up.

?

There are two main reasons why FSD is highly respected.

First, FSD is self-developed for Tesla. Tesla is the only OEM that automatically drives the whole stack and realizes mass production. From algorithms, hardware to chips, Tesla has absolute control over the core technologies.

Recently, Drive Pilot, a Mercedes-Benz L3-class system, was approved for commercial use in California, USA, but it uses NVIDIA Orin chip.

Second, FSD is the closest autopilot technology to mass production at present. As early as 2021, Tesla had already pushed the version of FSD Beta V9 (the beta version of FSD software) to 2,000 American users. As of the first quarter of this year, Tesla has400 thousandA car owner pushed FSD Beta, and the user has accumulated driving.190 millionMiles (approx.306 millionKilometers).

From the timeline, Tesla’s research on Autopilot assistance system can be traced back to September 2013. It has been nearly 10 years since Musk disclosed the research and development of Autopilot on Twitter.

As far as R&D cost and R&D results are concerned, car companies in the field of autonomous driving that have not yet entered the market or entered the market late are facing enormous challenges. At this time, Musk said that he wanted to open the FSD technology, just like leaving a big "pie".

On the bright side, Musk hopes to provide as much help as possible to other car companies, but he is still a businessman in the final analysis. It is probably not that simple to "help the world" at this key node that started in the second half of new energy vehicles.

In 2020, a serious crisis of mobile phone chips broke out in China. Under the sanctions of the United States, the chips of many enterprises in China cannot be mass-produced.

After September 2020, due to chip sanctions, SMIC’s required equipment was cut off, resulting in the failure to mass-produce the 14-nanometer chip orders received; In 2020, even if Huawei successfully developed the Kirin chip, it could not be mass-produced due to the lack of key equipment.

And this core equipment is EUV mask aligner, which can only be produced by ASML (Advanced Semiconductor Material Lithography, ASML) in the world.

However, in the research of mask aligner technology, China started very early. In 1965, China Academy of Sciences had developed the 65-type contact mask aligner, and ASML was not established until 1984.

However, at that time, the concept of "buying is not as good as renting" prevailed, and finally mask aligner and other sophisticated technologies were dismounted after the 1980s.

As a result, as you and I can see, in 2020, China’s mobile phone was strangled by the chip.

Fates are always strikingly similar, and the development of mask aligner has somehow advised domestic car companies to take a rational view of Musk’s opening of FSD.

FSD has become a "moat" recognized by Tesla in the field of intelligence, and autonomous driving is the general trend of automobile development, and it is definitely a battleground for all families.

For autonomous driving technology, car companies either develop their own or choose to cooperate with suppliers.

For new power brands that are not so big and have not delivered yet, driven by short-term interests, the development mentality of "self-research is not as good as rent" will be amplified to the extreme by FSD. The cost of choosing FSD is lower than that of self-research, and it can also superimpose Tesla’s influence buff, which seems to be a loss.

But if some enterprises really adopt this way, then the whole automobile industry in China may be taken care of by Tesla.

On the one hand, the disguised "price war" will probably change the R&D mentality of the industry. Even if it is not free, the probability of the authorized price of FSD will not be too high, and the automatic driving results invested by domestic car companies will gradually become worthless, so how many can continue to persist?

Under the vicious circle, will autonomous driving technology be exactly the same as mask aligner’s dismounting, and the whole industry in China will stagnate?

On the other hand, if a car company chooses FSD, it will be deeply adapted from the aspects of software and hardware, and any kind of materials, equipment and even accessories may be stuck. Once stuck, can your car be built?

On the other hand, even if it is not sanctioned, Tesla will wait until the technology fault of friends reaches a certain level before charging at a high price. Is there any way for car companies that have chosen FSD not to follow?

In the case that the basic R&D and the underlying facilities are not clear, adopting FSD is to lay a "thunder" for yourself in advance. Once dependence occurs, it is a matter of time before you get stuck.

So, don’t be afraid to walk slowly, at least we still have the opportunity to catch up.

However, we don’t need to sell ourselves short in autonomous driving.

Self-owned brands such as Tucki, SAIC Zhiji and Aouita have gradually realized "automatic driving" under our feet.

Tucki introduced the city NGP to users last year, and it was opened in Guangzhou, Shenzhen and other cities. It can realize the functions of overtaking, changing lanes, merging/exporting roads and avoiding pedestrians in busy urban roads. However, the usage scenarios of Tesla FSD are almost all on the sparsely populated roads in North America, and the road conditions are far less complicated than those in China. Therefore, some usage effects of NGP in Tucki may be better than FSD.

In addition, the NCA of Aouita Expressway has been covered.259A city,300 thousandKm structured road, accumulated mileage has exceeded.1 millionKilometers; SAIC Zhiji has pushed the high-speed NOA function on L7, which will be opened in Shanghai, Suzhou, Hangzhou, Jiaxing, Huzhou and other cities.

Companies such as Baidu Apollo and Didi Autopilot are also promoting the process of China’s autonomous driving industry. Baidu’s "Radish Run" unmanned self-driving vehicle has been operating in Yongchuan, Chongqing; Dongfeng enjoys the Sharing-VAN "Spring Bamboo Shoots" driverless bus running in Wuhan; Didi has achieved mixed delivery in Shanghai and Guangzhou, and users can call a car on the APP to experience Didi’s autopilot service …

For autonomous driving, Chen Hong, chairman of SAIC, said: "SAIC cannot accept the cooperation of third-party companies in autonomous driving, and SAIC should take its soul into its own hands."

This is not only the soul, but also the confidence to walk independently and resist foreign technological hegemony.

We can’t make autonomous driving the next mask aligner, do you think?

Cheng Siwei: It is misleading for real estate to be selected for industrial revitalization planning.


  According to media reports, Cheng Siwei revealed that the real estate industry has been included in the top ten industrial revitalization plans in the State Council. In this regard, the reporter of Economic Half-hour interviewed Cheng Siwei exclusively this morning. He told reporters that when he gave a class to students, he said that he had expounded his concern about the real estate revitalization plan based on relevant reports, but the media completely ignored this premise and misled his meaning when quoting him.


  Cheng Siwei: The selection of real estate for revitalization planning is misleading.


  (Reporter: Yan Wenyu, Gu Ping, Xiong Manlin, Jia Yujia Camera: Shen Yan, Xu Sheng, Zhang Xiaoming)


  Yesterday, the headlines of many websites were all the same news. It was reported that the real estate industry had occupied the last place in the State Council’s top ten industrial restructuring and revitalization plans. As soon as the news came out, various media and websites reprinted it one after another. The real estate sector in the stock market was also on the move, and a large amount of funds flowed into real estate stocks. At the same time, controversy and opposition were endless.


  Let’s take a look at our follow-up report on this matter.


  Yesterday, on several well-known domestic portals, the news that "real estate has entered the top ten industrial revitalization plans" suddenly made headlines. At the same time, when searching for two keywords "real estate" and "revitalization plans" through search engines, almost all major websites reported or reprinted it, attracting countless eyeballs.


  On January 2nd this year, Premier Wen Jiabao of the State Council said that the State Council was studying the adjustment and revitalization plan of ten important industries. Subsequently, eight industrial revitalization plans for automobiles, steel, textiles, equipment manufacturing, ships, electronic information, light industry and petrochemicals were reviewed and approved in principle by the the State Council executive meeting. During this period, the non-ferrous metal revitalization plan has been initially approved by the State Council. So which industry will be selected into the tenth industrial revitalization plan of the State Council is full of suspense.


  Yesterday, with the news that the real estate industry has caught the "last bus" of the top ten revitalization plans, the market quickly responded. In yesterday’s stock market, the net inflow of funds from the real estate sector topped the list. Real estate stocks not only floated across the board, but also hit an average growth rate of 4.64%, breaking the weak trend of real estate stocks since this round of market.


  However, after the closing yesterday afternoon, some media said that real estate was unlikely to be included in the revitalization plan, which made many investors feel extremely confused. Economic Half-hour reporter traced back to the news that "real estate has entered the top ten industrial revitalization plans", and found that the media that first reported the nine industrial revitalization plans were all Xinhua News Agency, and the sources were all the State Council executive meeting. This time, the media that first reported "real estate has entered the top ten industrial revitalization plans" was not Xinhua News Agency, nor was it the State Council, but quoted Cheng Siwei, former vice chairman of the National People’s Congress Standing Committee (NPCSC), at an academic forum last Saturday. It was reported that during the speech, Cheng Siwei


  So, did Cheng Siwei say that the real estate industry has really entered the top ten revitalization plans, and through what channels did he get the news? The Economic Half-hour reporter made an exclusive interview with Cheng Siwei this morning.


  Reporter: "Cheng Lao, I saw such a news on the Internet yesterday that real estate was included in the top ten industrial revitalization plans. So, stimulated by this news, real estate stocks also rose by 4.64% on average. I wonder if you have noticed this news?"


  Cheng Siwei: "I have seen it. In fact, I told them at that time that it was not news, and they wanted to quote it. They told me that the secretary had already posted it, so there was no way, but in fact, this was when I was giving lectures to my students, and it was not a public report."


  On Sunday, some media reported that Cheng Siwei revealed that the real estate industry has been included in the State Council’s top ten industrial revitalization plans, and Cheng Siwei’s photos were also used in the report, while Cheng Siwei told reporters that he talked about this matter when he was teaching students, not a press release.


  Reporter: "through what channels did you learn that this real estate industry has been written into the national industrial revitalization plan?"


  Cheng Siwei: "First of all, I saw the news released by Securities News on February 17th from People’s Daily Online. I also printed it out today. The headline of this news is called, officials of the Energy Bureau said that the energy industry revitalization plan was replaced by real estate planning. In addition, on People’s Daily Online, if you click on it, you can also see the real estate industry in the top ten industrial revitalization plans, so I, I personally got the information from this aspect."


  Reporter: "Besides this news on the Internet, do you have any other channels to confirm what you have seen?"


  Cheng Siwei: "It seems that I read on the Internet that on the 22nd, officials from the Ministry of Housing and Urban Development also said that this was the case, because to be honest, as a scholar, I just expressed my views, and I can’t make any explanation on behalf of the government. This is just what I said on the basis of the published news, so I also said that it was reported that there was such a situation."


  The report on February 17th mentioned by Cheng Siwei is like this: "People from the National Energy Administration said that the plan to introduce another energy sector in addition to the nine major industry revitalization plans has been replaced by the relevant plans of the real estate industry"; The website mentioned by Cheng Siwei is a special page of People’s Daily about the revitalization plan of China’s top ten industries, which indicates a total of ten industries, and the real estate industry suddenly appears in it. However, unlike other reports on the revitalization plan, the so-called real estate revitalization plan has never heard from the the State Council executive meeting, and all the first reports are not from the news broadcast of Xinhua News Agency and China TV Station, but a media claimed that they were confirmed by an official of the Ministry of Housing and Urban Construction.


  Reporter: "Generally speaking, what is a channel and a formal channel for the release of such a plan?"


  Cheng Siwei: "As far as I know, the report is like this. He is planning one by one, first reviewed by the National Development and Reform Commission, and then submitted to the the State Council executive meeting for deliberation. Therefore, I think this procedure should be like this. Before the State Council officially passed, the content of the plan was impossible. Release."


  Reporter: "Take a look, this webpage is generally reported in this way. The topics are all called real estate listed in the top ten revitalization industries. Has it been confirmed?"


  Cheng Siwei: "Well, I don’t watch it. It’s inappropriate for him. In fact, at that time, I asked my secretary of the Chinese Academy of Sciences to tell them that it was simply a hype, not news."


  Cheng Siwei said that when he was teaching students, he said that he expounded his concern about the real estate revitalization plan based on relevant reports, but the media completely ignored this premise and misled his meaning when quoting him.


  Reporter: "Do you think this presentation is your original intention?"


  Cheng Siwei: "I think this is a bit misleading, which is what I said just now. In fact, this news was announced on the 17th, and when I spoke, I said that I was giving lectures to students, so it was reported that this should be very clear. But because I have repeatedly said that I am now from the National People’s Congress, even if I am the vice chairman of the National People’s Congress, I don’t care about the government, and now I have retired from the post of vice chairman of the National People’s Congress, so what I am talking about now is all. Therefore, I think it is a matter of the National Development and Reform Commission, the Energy Bureau and the Ministry of Construction, so I think this report is not accurate. "

New cars are piled up for the first time, and the price continues to be "discounted"! The Guangzhou Auto Show starts the final battle of the auto market

On November 18, 2023, the 21st Guangzhou International Automobile Exhibition ushered in the first professional audience day. ic photo

The Guangzhou Auto Show is the last large-scale auto show of the year, and it has naturally become the starting gun for the final battle of car companies at the end of the year.

This year’s Guangzhou Auto Show is still hot, and car companies have brought their blockbuster products and huge sales teams to the show. According to the organizers of the Guangzhou Auto Show, the total number of vehicles on display at this year’s Guangzhou Auto Show is 1,132, including 469 new energy vehicles.

It is worth noting that in the increasingly fierce competitive environment, car companies have accelerated the pace of new car launches in order to boost sales. There are as many as 59 cars in the world for the first time at this year’s Guangzhou Auto Show, and new car launches have been held intensively. Many brands have launched new blockbuster models, which will also add to the national auto market’s year-end impulse.

The competition for new products is intense, and price reduction is the main theme

New products have been an effective way for automakers to boost sales, especially in the first year of a new car’s launch. In the Chinese market, automakers have "rolled" the development cycle of new energy vehicles from the past five years or so to 48 months or even 36 months.

According to the organizers of the Guangzhou Auto Show, at this year’s Guangzhou Auto Show, there are as many as 59 cars in the world, including 8 first cars from multinational companies. In comparison, there were 38 cars in the world at last year’s Guangzhou Auto Show, including 9 first cars from multinational companies.

There are many models with high attention in the first car, such as BYD Ocean Network’s first medium-sized pure electric SUV, Hishi07 EV, Great Wall’s tank 700 Hi4-T, Huawei Hongmeng Cockpit 4.0-blessed Zhijie S7, Xiaopeng’s first MPV model X9, Li Auto’s first pure electric flagship model MEGA, and so on.

An employee of a car company participating in the exhibition told the surging news reporter, "This year’s Guangzhou Auto Show new car launches are so crowded that there are many overlapping parts in the same hall, and the leaders are simply selling cars at the top of their throats."

In addition, in this year’s model launch, it can be seen that car companies are cautious in pricing. The official price announced by many first models is lower than market expectations or lower than the price of previous generation models.

For example, the delivery price of Polaris 4 released by Polaris during the Guangzhou Auto Show was 299,900 yuan to 399,900 yuan. Compared with the price displayed at the Shanghai Auto Show in April, it decreased by about 50,000 yuan. It is not difficult to see from this price adjustment that in the face of competition in China’s new energy vehicle market, Polaris is eager to participate in it by reducing prices.

At the Guangzhou auto show, car companies have offered sincere discounts. Similarly, car company executives no longer give a negative or secretive attitude to the "price war".

"In addition to price, customer trust is also one of the factors to maintain brand competitiveness," Meng Xia, chief executive of Volkswagen’s passenger car brand in China, said at the auto show. "Volkswagen will not compete solely on price." He also said that in China, it is committed to providing consumers with excellent products at attractive prices, but not just reducing prices.

Volkswagen can be said to be the beneficiary of the price war in the car market. After launching a sharp price reduction of the pure electric ID family in July this year, the sales of the Volkswagen ID series soared. In particular, the Volkswagen ID.3 achieved a nearly four-fold increase in sales in the second month after the price reduction.

The car market has intensified, making it difficult for car companies to make money

Driven by a large number of new cars at the Guangzhou Auto Show, as well as price cuts and promotions by car companies, the auto market at the end of the year was generally optimistic.

The latest data from the Passenger Federation shows that from November 1st to 12th, the retail sales of the passenger car market was 538,000, an increase of 18% over the same period last year. The Passenger Federation believes that with the gradual strengthening of the car market, car companies are looking forward to working hard to achieve the annual target. The confidence of the car market is enhanced, and the year-on-year growth of the car market in November is expected to reach more than 20%.

The passenger association believes that this year’s car market can steadily reach the expected sales of 9 million vehicles in the whole year. Some institutions have also given more optimistic expectations.

Dongguan Securities believes that the fourth quarter is the traditional peak season of the automobile market, the national and local policies to promote the consumption of new energy vehicles are expected to continue to exert force, new products of car companies have been launched one after another, and at the same time, another round of price reduction promotions has been opened to stimulate further release of demand.

However, the increase in sales of new energy vehicles has not eased the current intense "involution", and the profitability problem is still a major problem plaguing car companies.

During the Guangzhou Auto Show, Zhuang Jingxiong, general manager of SAIC General Motors, was even more blunt, saying that selling new energy vehicles "is too embarrassing to say hello if you don’t lose money now."

Huatai Securities said in its latest research report that the auto industry discount rate has still been rising since November. The agency’s tracking data shows that the current average discount rate in the auto industry is 5.93%, compared with less than 3% in the same period last year. The latest data from the National Bureau of Statistics also showed that the price of new energy passenger vehicles fell by 4.6% year-on-year in October.

As competition in the auto market intensifies, the survival of the fittest in the industry is accelerating. Liu Jie, vice president of Li Auto’s business, said in an interview with The Paper and other media, "2023 to 2025 is the elimination stage of new energy vehicles. By the end of next year, the top few winners should have basically stabilized, and the new energy companies on the card table will further expand their market share in the later stage."

In fact, this year’s Guangzhou Auto Show has already seen the absence of many well-known brands, such as GAC Mitsubishi, which has just announced its withdrawal from the Chinese market, Weimaraner and Aichi, which are in business difficulties, and Dongfeng Peugeot Citroen, which launched a price war at the beginning of this year.

Guangzhou Automobile Chuanqi finally shines the trump card, and the luxurious sense of sports is brand-new Chuanqi GS3 real car.

The most intuitive change of the new car is the adoption of a brand-new design style language. The car design style continues the family design concept, the front face design is thick, the headlights on both sides are sharp, and the internal light groups are patchy and bright. From the side lines, the new car is still a simple sense of strength, the tradition of wide C-pillar can be continued, and in addition, it makes its sports atmosphere more intense. The tail design is still relatively rounded, and the taillight design also has a certain sense of advanced.

In terms of interior, this car is also very textured. The car uses a relatively sporty steering wheel in the car, which instantly improves the grade of the whole car. The top of the center console is covered with a large area of soft enamel, which improves the touch. It is equipped with an 8.0-inch LCD screen, which is clear and relatively young in design. The front row is also equipped with an automatic air conditioning control system to freely debug the most comfortable space atmosphere. Leather seats give passengers just the right support and soft and comfortable touch.

The length of the car is 4410mm, the width of the car body reaches 1850mm, and the wheelbase is 2650mm, which is quite satisfactory. In the same class, the wheelbase of Chuanqi GS3 ranks 70th. As an SUV, its body size does not occupy much advantage in its class, and its internal seating space is only basically enough. After all, it is limited by the length and shape of the body. Chuanqi GS3′ s skylight with a speed of 270T Jinzhi MAX provides a wider field of vision, which can create a better visual environment and good sensitivity for the rear passengers and increase the light entrance for the whole vehicle. Among the models of the same price and class, the trunk volume of Chuanqi GS3 ranks 47th. Spatial performance is limited by vehicle positioning, and the performance is acceptable, and the flatness is no problem, but the total space is average.

Chuanqi GS3 film speed 270T Jinzhi MAX version adopts 1.5 engine, with maximum horsepower of 177 and peak torque of 270, matching wet dual clutch (DCT) gearbox. The whole power parameters are superior in power performance among engines of the same class, which can provide better power performance. Ranked 34th among 80,000-120,000 SUV models.

Chuanqi GS3 has complete active/passive safety configuration, includingAutomatic parkingZero tire pressure endurance tireAutomatic parkingSteep slope descenthill start assist controlknee airbagHUD head-up displayAnti-lock braking (ABS)Braking force distribution (EBD/CBC, etc.)Brake assist (EBA/BAS, etc.)Traction control (ASR/TCS, etc.)Active noise reductionEngine start and stopSide safety air curtainWireless charging of mobile phonenight vision systemLED daytime running lightsForward reversing radarTire pressure monitoringSteering wheel heatingBody stability control (ESP/DSC, etc.)Rear reversing radarFatigue reminderRemote parkingChild seat interfaceLane keeping (LKAS)Equal configuration.

How "cold" is the cold wave? Big data tells you!

  Tell everyone a "cold" news, the strongest cold wave since the winter of this year is coming soon! It is predicted that from November 26th to 30th, the cold wave will sweep across China, and the temperature will plummet in most areas.

  Speaking of the cold wave, many people have memories dominated by it. As the "strongest" cold air, how "cold" is the cold wave? What is the strongest cold wave in history? The reporter interviewed Ye Dianxiu, a senior engineer under research at the National Climate Center and the chief expert of meteorological services at the China Meteorological Bureau, and asked him once and for all.

  1. What is the standard of cold wave? Is there a difference between the north and the south of China?

  Cold wave is a kind of cold air and a kind of disastrous weather. According to the national standard of cold air grade in China (GB/T 20484-2017) formulated in 2017, the cold air activity that makes the daily minimum temperature in a certain place lower than or equal to 8℃ within 24 hours, or lower than or equal to 10℃ within 48 hours, or lower than or equal to 12℃ within 72 hours is called cold wave.

  2. How strong is the "ability" of cold wave cooling?

  Monitoring shows that the average cooling rate of each cold wave in most parts of China is above 10℃. The average cold wave cooling rate in most parts of Northeast China, Jianghuai, eastern Jianghan, Jiangnan and southern China, as well as most parts of Inner Mongolia and northern Xinjiang can reach 12.To 14℃, more than 14℃ in most areas of Guangdong and Guangxi.

  The maximum cooling range of cold waves in Northeast China, most of North China, most of Northwest China, most of Huanghuai, most of Jianghuai, southern Jiangnan and most of Inner Mongolia and Tibet is above 20℃. Among them, the maximum cooling rate in most parts of Northeast China and Inner Mongolia, northern Xinjiang, northwestern Tibet and southwestern Qinghai can reach 25.To 30℃, more than 30℃ in some areas; The maximum cooling range of cold wave in Sichuan basin, most of Yunnan and Hainan is below 15℃, and that in other parts of the country is generally below 15℃To 20℃.

  3. How many cold waves occur on average every year in China?

  In China, cold waves mostly occur in late autumn, winter and early spring. In the past 30 years (1991-2020), cold waves have occurred 5.4 times a year on average in China.

  Since 1991, the most frequent cold wave occurred in 2021, with 11 times. Followed by 2009, there were 8 times, and the least number of cold waves was in 2017, only 2 times.

  4. Where did the cold wave affect our country come from?

  The cold air affecting China can be roughly divided into the following four paths:

  ① Northwest route: Cold air enters China from the White Sea and Barents Sea west of Xindi Island via Siberia and Mongolia in the west.

  ② Northern route: Cold air enters northern Asia from Kara Sea or Novosibirsk Sea east of Xindi Island, and enters China from north to south via Mongolia.

  ③ Western route: Cold air affects eastern China from west to east in Eurasia south of 50 degrees north latitude via Xinjiang.

  ④ Northeast route: Cold air from the Sea of Okhotsk or eastern Siberia affects the northeast of China.

  more thanPath,The first three paths are more common, while the last path is less frequent and less intense.

  5. What are the cold waves with large temperature drop in history?

  According to the monitoring results of cold air process, since 1991, the top five cold waves with comprehensive cold air intensity in China have appeared on November 4-9, 2021, March 11-14, 2006, March 18-22, 1998, February 14-17, 2020 and April 11-17, 2006.

  Cold waves often bring a wide range of severe cooling, strong winds and snowfall. Taking the cold wave process from November 4 to 9, 2021 as an example, the land area with the temperature drop exceeding 8℃ is 7.709 million square kilometers, accounting for about 80.3% of the national land area. Among them, there are 1.011 million square kilometers whose temperature drop exceeds 16℃.

  The daily minimum temperature of 172 national meteorological stations in Xinjiang, Gansu, Qinghai, Ningxia, Shaanxi, Shanxi and other places reached or exceeded the historical extreme value in early November.

  The daily precipitation of 151 national weather stations in Liaoning, Jilin, Heilongjiang, Inner Mongolia, Hebei, Tianjin, Shanxi, Shandong and other places exceeded the historical extreme in November. There is obvious snow in many places in the north, and the depth of snow in Inner Mongolia, Jilin and Liaoning is more than 40 cm.

  6. Where is the place most favored by the cold wave in China?

  In China, the frequency of cold wave is characterized by more in the north and less in the south. The areas most favored by cold waves include: Northeast China, western and northern parts of North China, northern and central parts of Northwest China, most of Tibet, Inner Mongolia and other places, with an average annual cold wave frequency of more than 4 times. Among them, there are generally 10 to 15 times in the eastern and northern parts of Northeast China, most of Inner Mongolia and parts of northern Xinjiang, and there are more than 15 times in some areas.

  7. In cold winter, are there more cold waves than in warm winter?

  The answer is no.

  There are obvious differences in judging factors and time periods between cold winter and cold wave, and the annual cumulative cold wave frequency is not necessarily related to cold and warm winter. Cold winter is a kind of climate concept based on the temperature condition of the whole winter, and the basic element of judging cold and warm winter is the average temperature of winter (December to February) for three months. The basic factors to judge the cold wave process are the daily minimum temperature (≤4℃) and the 24-hour (or 48-hour, 72-hour) cooling range (≥8℃, 10℃ or 12℃).

  Therefore, the number of cold waves in cold winter is not necessarily more than that in warm winter. For example, both 1998 and 2019 were strong warm winters, and the number of cold waves was 6, which was more than that of strong cold winters in 1983 (3 times), 1984 (2 times) and 1985 (2 times).

In simple terms, it is the plug-in version. We have a real shooting experience in front of it, so let’s taste this one together.

   

  First of all, you can see that in terms of appearance, the E9 uses a banner-type chrome-plated trim, officially called "Kunpeng Spread Wing", which seems to be closer to the positioning of new energy models.

  In terms of body size, the length, width and height are respectively: 5193/1893/1823 (mm), which is 3070mm, and is positioned in the medium and large MPV, which is on the same level as competing models such as Saina and D9.

   

  In terms of interior, the Trumpchi E9 continues the cockpit design of "Swan Wings", and has two interior themes of "Opera Palace" and "Yunshan Zhushui". The difference is that the Trumpchi E9 adds a 12.3 multimedia entertainment LCD screen to the passenger, forming a three-screen take-off visual effect.

  In terms of seats, the real model adopts a 7-seat layout of 2 + 2 + 3, in which the second row supports rich functions such as seat electric adjustment,/heating/massage, which is very close to the definition of land first class. Not only that, the second row is also equipped with a display screen on the roof, which can maximize the life in the car.

  In terms of power system, the Trumpchi E9 is equipped with a self-developed 2.0TM hybrid special engine + GMC 400 hybrid special transmission + 25kW · h magazine battery pack. Under this power combination, the WLTC operating condition of the whole car has a comprehensive battery life of over 1000km, and the WLTC feeds a hundred kilometers of fuel consumption of 6.05L. Among them, the 2.0TM maximum power is 140kW, the maximum torque is 330N · m, and the official 100-kilometer acceleration time is 8.8s.

  After a series of experience is not difficult, Trumpchi E9 is full of competitiveness, it has achieved a full standard in all aspects, and the newly added 2.0T plug-in system has greatly improved its competitiveness, combined with the pre-sale price of 33-390,000 It seems that there is no doubt that Trumpchi E9 will be a competitive luxury MPV.
