A few days ago, the author learned from relevant channels that the 2023 Guangzhou Automobile AION V Plus has added a 707-seat business model with an official guide price of 196,800 yuan. The difference between the new car and the cash is concentrated in the configuration part, while in terms of power, the layout of the front single motor is adopted. In addition, it is worth mentioning that the 2023 Guangzhou Automobile AION V Plus 70 Smart Collar Edition also fine-tuned the configuration, added the lumbar support function of the main driver’s seat, and the price remained unchanged at 189,800 yuan.

As a new model, the appearance and interior design layout of the 2023 Guangzhou Automobile AION V Plus 70 seven-seat business version is not expected to be much different from the models currently on sale, and from the price point of view, the new car will become the entry-level version of the 2023 Guangzhou Automobile AION V Plus seven-seat series. Compared with the guide price of 206,800 yuan, the 70-seat version lacks lane departure warning, lane keeping assistance, road traffic sign recognition, active braking, fatigue driving tips, lane keeping in the middle, front collision warning, wireless charging of front mobile phone, electric adjustment of co-pilot seat, heating/ventilation of front seat, memory of main driver seat, fragrance system in the car, ETC., and only supports constant speed cruise, but it has ETC vehicle-mounted device and openable panoramic sunroof.

In terms of power, the new car continues to be equipped with a driving motor with a maximum power of 165 kW and a peak torque of 350 Nm, and uses a ternary lithium battery with a capacity of 69.9 kWh as an energy storage device. Under NEDC working conditions, the pure electric cruising range is 500 kilometers. In addition, the 2023 Guangzhou Automobile AION V Plus seven-seat series models also provide a 600-kilometer (NEDC working condition) endurance version for consumers to choose from.

Summary: As a compact SUV owned by Guangzhou Automobile Ai ‘an, the 2023 AION V Plus currently on sale was first launched in August this year. From the price and positioning, its competitors in the market include SAIC Volkswagen ID.4 X, Nezha U and BYD Song PLUS EV.

The arrival of the 707-seat business edition has further lowered the price threshold of the 2023 Guangzhou Automobile AION V Plus seven-seat series. Of course, its configuration level has dropped to some extent compared with the previous entry-level version, and it is expected that some consumers with limited car purchase budgets and not relying on driver assistance functions will have certain appeal.

In recent years, policy support and increased demand have promoted the continuous growth of the number of two-wheeled electric vehicles. The overall development of the industry has made brand competition more intense, and intelligent transformation and safety improvement have become the focus of competition among two-wheeled electric vehicle manufacturers. It is in this situation that Company No.9 (689009·SH) quickly created its own differentiated competitiveness through true intelligence, and created one proud achievement after another.

Offline exceeded 5 million units! No.9 company refreshes the "acceleration" of two-wheeled electric vehicles in China

A thorough study of the history of No.9 Company’s entry into the two-wheeled electric vehicle industry will reveal that compared with other brands, more than four years is really not a long time. But it is this short time that Company No.9 has become an indispensable and irreplaceable existence in the industry.

Not long ago, the fifth millionth intelligent two-wheeled electric vehicle of No.9 Company successfully rolled off the assembly line, and it was only over three months since the fourth millionth one rolled off the assembly line. The amazing growth rate record took 27 months from the first million units, gradually shortened to 11 months, 7 months and 4 months, and increased by 1 million units in the last three months. This is rare in the whole industry. It can be said that it has refreshed the "acceleration" of two-wheeled electric vehicles in China and set a new benchmark.

Not only that, Company No.9 also won four market position confirmations: "Top-end electric vehicles sold nationwide", "Smart electric vehicles sold nationwide for two consecutive years in 2022-2023", "No.9 for every 10 smart electric vehicles sold by China Smart Electric Vehicle Brand" and "China Electric Vehicle Young People’s Preferred Brand", and it is a well-deserved leader in the smart two-wheeled electric vehicle industry.

Operating income reached 4.239 billion yuan, up 34.75% year-on-year, and Q3 performance of No.9 Company reached a new high.

In addition to the amazing success of 1 million units in three months, recently, No.9 Company released its financial report for the third quarter of 2024. The data shows that the company’s operating income in Q3 reached 4.239 billion yuan, up 34.75% year-on-year. The net profit attributable to shareholders of listed companies was 374 million yuan, up 139.07% year-on-year;

It is worth mentioning that, as one of the fastest growing businesses of No.9 Company in recent years, the intelligent electric two-wheeled vehicle achieved 936,300 units in China in the third quarter, and the cumulative domestic sales in the first three quarters reached 2,134,700 units, up 86.08% year-on-year. In addition, this year’s new product No.9 electric motorcycle M95c+ reached the top of the electric motorcycle sales list of Tmall, JD.COM and Tik Tok at the same time, No.9 electric motorcycle from MMAX2 110P won the first place in the electric bicycle sales list of JD.COM and Tmall, and No.9 electric motorcycle N70C won the first place in the electric motorcycle sales list of Tik Tok.

Each of these data proves the strength of Company No.9, and shows that it occupies an indisputable position in the two-wheeled electric vehicle industry. In the future, Company No.9 will continue to maintain this "acceleration", constantly improve the quality of its products and services in the fierce competition, meet the diverse needs of consumers for smart travel, and at the same time promote the high-quality development of the brand itself and the whole industry.

1905 movie network news On July 10th, the film premiere was held in Beijing. The director took the lead role of,,,,,,,,,,,,, and talked with the audience behind the scenes.

It has been nine years since its preparation, and it happens to be the same age as director Wu Ershan’s eldest son. For him, the film is also like his own child. "This is a mythical epic that embodies everyone’s dreams and talents. I want to express my feelings along the way with a famous Mongolian saying: Don’t hesitate because of the long distance, as long as you go, you will arrive."

When talking about why ChristianRandPhillips and Bo Huang were chosen to play Zhou Wang and Jiang Ziya, Wu Ershan said that in the face of these two familiar figures, the master wanted to find a solid basis from the historical texts and bring a brand-new feeling to the audience. "Xunzi described Yin Shou:‘Long and beautiful, the best in the world; The strength of the muscles is strong, and the enemy of a hundred people is also.’It is simply tailored for ChristianRandPhillips; The image of Jiang Ziya played by Bo Huang comes from the original novel "Romance of the Gods", hoping to present a Jiang Ziya that is different from the traditional image. "

ChristianRandPhillips, who returned to the big screen after many years, also said that it was a great honor to play such an important role. In order to achieve the status of Zhou Wang, she also paid a lot of attention to body management and even started to exercise at 3: 30 in the morning. Huang Bo described Jiang Ziya as a "valve" to adjust the tightness in the play. "In such an epic drama, the characters must be rich, and Jiang Ziya is a clue character to adjust the rhythm."

As a big fan of ChristianRandPhillips, being able to play the role of Queen Jiang is undoubtedly a dream-fulfilling journey for Yolanda. What’s more interesting is that her husband Xia Yu is also in the same crew. Yolanda said with a smile that when he joined the group, Xia Yu was not in the group, "so that I can appreciate idols more intently."

On the same day, Li Xuejian, a performance artist who plays Xibo Hou Jichang, also came to the premiere. He interpreted his role in this way: "Ji Chang suffered a great shame that human beings could not bear in order to realize his original intention. His original intention was to make the weak country stronger and his people rich. I have two sentences:‘By hook or by crook, you are not a hero.’Dedicated to Shang Zhouwang;‘What a hero if you don’t change your mind’Dedicated to Zhou Wenwang. "

　　Moderator Shui Junyi:

　　Good evening, everyone. Welcome to Global Sight, which is being broadcast live on the news channel. I’m Shui Junyi. Russian President Vladimir Putin published an article in The New York Times, which mercilessly attacked the US government, which caused an uproar among American media and politicians. The heavyweight Senator Menendez publicly said that he almost wanted to vomit after reading Putin’s article. The White House also made a fierce counterattack. What did Putin write to make Americans so angry? In addition, Syrian President Bashar al-Assad recently said in an interview with RIA Novosti that Obama must promise not to arm the opposition, otherwise he will not hand over chemical weapons. What does such a tough stance mean? Will it be the reason for the United States to attack it again? Today, our studio invited special commentators, Mr. Yin Zhuo and Mr. Song Xiaojun, to participate in our discussion. First of all, let’s take a short film to learn the details.

　　Commentary:

　　The dramatic situation in Syria has made progress again after Obama announced his request to Congress to postpone the vote on the military strike against Syria. On the 12th, the Syrian government submitted relevant documents to the United Nations on its accession to the Chemical Weapons Convention. The United Nations said that this means that Syria has officially started the process of accession to the Chemical Weapons Convention. On the same day, the Permanent Representative of Syria to the United Nations, Jaafari, said that in a legal sense, Syria has become a member of the Convention.

　　On the same day, the Russian media broadcast an interview with Syrian President Bashar al-Assad.

　　President Bashar al-Assad of Syria:

　　I want to reiterate that without Russia’s proposal, we would not discuss the transfer of chemical weapons with any country, saying that Syria was threatened to give up chemical weapons, which is a propaganda means of the United States, because Kerry and Obama always want to show the United States as a winner who achieved their goals through threats.

　　Commentary:

　　At the same time, in the interview, Assad once again denied that the Syrian government used chemical weapons. He said that the chemical weapons attack on the outskirts of Damascus on the 21 ST of last month was caused by terrorists to provoke the United States to use force against Syria. They have chemical weapons provided by foreign countries, and Syrian government forces have never used chemical weapons. In recent days, Obama’s plan to attack Syria militarily is under siege, and Russia’s plan of exchanging chemical weapons for peace has received more and more international support. Since Obama announced the postponement of the plan, the chemical weapons crisis in Syria seems to have begun to develop in a good direction. However, the game between the United States and Russia on the situation in Syria is still going on.

　　On the 12th, a long letter to the American people and political leaders was published in the The New York Times that day, and the author was Russian President Vladimir Putin. In the article, Putin warned the United States that "military strikes against Syria will only bring chaos and casualties." And pointed out that "many countries no longer regard the United States as a model of democracy, but only know how to play rough." For this article, the British "Guardian" said that while Putin extended a hand of friendship and cooperation to Obama, he repeatedly stabbed Obama’s wound with a knife. Just a few hours after Putin’s article was published, US Secretary of State Kerry flew to Geneva, Switzerland, and held talks with Russian Foreign Minister Lavrov on the Syrian chemical weapons for peace plan. The New York Times commented on the dramatic changes in the Syrian situation. Just as Obama hesitated, Putin stood in the center of the stage. However, some commentators believe that even if the proposal of exchanging chemical weapons for peace becomes a reality, it will still face many political and operational difficulties in real implementation. However, there are still variables whether the United States, Russia and Syria can reach a preliminary plan for the solution of chemical weapons. At that time, will the United States still put a military strike plan on the table, and how will the situation in Syria develop? Still worthy of attention.

　　Moderator:

　　There was a sentence in the second half of the short film just now, which I think left a deep impression on me, saying that Putin stood in the center of the stage just as Obama hesitated. Before the next conversation today, there is a very popular video from Russia today. Please watch it together. As we all know, the most popular column in the world, including China, is called "The Voice of China". Not long ago, it was said that Putin also made a good voice in Russia, and not only did he make a good voice in Russia, but he also won the turn of three tutors. This was the scene at that time, and the picture quality was average.

　　Let’s look at this picture and ask for advice. This is Putin’s side. In addition, of course, we have seen that Putin has many other sides, but it really surprised many people, including many Americans. Putin still has such a skill, that is, he wrote a commentary in the The New York Times, a best-selling newspaper in the United States and the western world, which suddenly caused such an uproar. What do you think of Mr. Yin?

　　Yin Zhuo Special Commentator:

　　I think Putin wants to light another fire, give Obama another push and push him down when public opinion, especially domestic public opinion, is unfavorable to Obama.

　　Moderator:

　　What do you mean?

　　Expert opinion: Putin "lights a fire" on Obama’s unfavorable public opinion.

　　Yin Zhuo:

　　Because we know that Obama decided to go to war this time, he had already crossed the red line, and now Bashar al-Assad’s regime has crossed the red line and decided to use force, and he has made a lot of hard words, whether your parliament agrees or not, I will use force, I have the right to use force, and so on. Now the domestic public opinion and the public opinion of the whole parliament are unfavorable to him. He feels that the number of votes is unfavorable to him and the possibility of passing it in the parliament is very small. Moreover, public opinion is widespread, and more than 60% of Americans oppose the use of force against Syria.

　　Moderator:

　　It is basically impossible to get such support in parliament.

　　Yin Zhuo:

　　In mainstream public opinion, in opinion polls, there is no such support. And Putin now, it turns out that he wants to stand on the moral high ground against Russia, that is, you used weapons of mass destruction as an excuse to use force against Syria. Of course, he is standing on the moral high ground, because big countries kill weapons, which is prohibited by international law.

　　Moderator:

　　The whole world opposes it.

　　Commenting: Putin severely criticized the abuse of power by the United States

　　Yin Zhuo:

　　But also killed many women, especially children, and children suffered a lot of casualties, so he stood on the moral high ground. On the other hand, now he has stood morally low, Putin has stood high, and Putin has clicked on this article again. You won the Nobel Prize, but you had better fight. You are a militant. At this time, Putin has become the commanding height of morality, but he is a militant. Put aside the use of chemical weapons, because Putin took it out because of the drastic measures. Bashar handed over the whole chemical weapons. Is it possible for you to use force? Now Putin stands on the moral high ground and asks him to promise not to use force. The United States will never promise. It is precisely because of such a contrast that he lost his moral points.

　　Moderator:

　　Let’s take a look at what Putin wrote on the The New York Times. In one passage, he said, "I doubt that many people all over the world now feel more and more that the United States is not a model of democracy, but only resorts to brutal force and forms gangs under the slogan of being either friends or enemies." In addition, he said that no matter how clear the target is and how sophisticated the weapons are, it is impossible to avoid civilian casualties, including the elderly and children, those who wanted to protect through action. "

　　In fact, he also said a passage, which we didn’t extract. He said that the United States should not always feel unique or different from the rest of society. You are actually a member of the international family. Therefore, in addition to some politicians in the United States, including the White House, who will immediately fight back later, many commentators say that Putin is very reliable. You see, he helped me in a difficult situation; Some people say that this year’s Nobel Peace Prize belongs to Putin. What does Mr. Song think? The so-called Putin gave Obama a hand at a critical moment, and now he is standing on such a commanding height to teach a lesson. Americans say not to think that Americans are unique in the world?

　　Expert opinion: Putin not only gave "steps" but also "helped them down"

　　Song Xiaojun Special Commentator:

　　Putin not only helped Obama, but also gave him a step and helped him. Therefore, in this case, it was Obama who was riding a tiger. The United States conducted a Gallup survey in the same period. The wars fought in the past 22 years, the Gulf War and the Iraq War, including Kosovo, were many times, including opinion polls. This time it was the lowest, 36%, like 82% when it was fought in Afghanistan, that is, in 2001, after the "September 11" incident, when it was fought in Iraq. But this time it’s 36%, and it’s still falling. How do you think Putin can get down this step? People give you a step to help you, what should they get? What I got was the good voice we talked about just now, and why he showed such an image this time, and even wrote this article in The New York Times, which shows that Putin is now facing internal problems in Russia, because local elections are about to be held in Russia. Moreover, Russia’s economic situation is not good now.

　　I saw the BRICS in the previous G20. In our BRICS countries, no one can do it except China, and the Russian people’s support rate for the United Russia Party is now declining. At this time, Putin has to use his personal charm to unite the Russian Party on the international stage, or win back the votes of his team in local elections, so he wants this.

　　Moderator:

　　But in any case, Obama is good, and his team seems to feel that Putin’s popularity is a bit overwhelming. Don’t forget Obama’s team. Some people say that they have always wanted to build Obama according to a star. Now there is a response to Putin’s high praise. Let’s listen to what he said.

　　Carney White House spokesman:

　　Unlike Russia, the United States represents the value of democracy and human rights in our own country and around the world. We believe that when children will not be killed by a dictator with poison gas, the global security level will also be improved.

　　Now 34 countries have claimed that the Assad regime was responsible for the use of chemical weapons that night.

　　I think it is also necessary to point out that it is a great irony to publish such a column, because it reflects the truly outstanding tradition of freedom of speech in this country, which is not shared by Russia. In the past few years, freedom of speech has greatly declined in Russia.

　　Commenting: The White House retorted and the war of words escalated.

　　Moderator:

　　Regardless of everything else, Carney typed it right away. There is no freedom of public opinion in Russia. Look, your president has to publish a commentary in my newspaper. But a very simple question may also be a hypothetical one, Mr. Yin, because we know that many things in Nobel are manipulated by Americans, and Americans will let Putin, if someone really nominates Putin for this year’s Nobel Peace Prize, is it possible? Is there a play?

　　Yin Zhuo:

　　Impossible, absolutely impossible.

　　Moderator:

　　Why?

　　Expert opinion: the United States will not give Putin the title of "peacemaker"

　　Yin Zhuo:

　　Because the Nobel Peace Prize has a very strong political ideology, its political ideology is on the side of the United States. Since it awarded the Nobel Peace Prize to Obama, it shows that people like Putin can never win the prize here, otherwise Putin will stand up against his own country’s system, so he wants to win the Nobel Prize. From here, we can see that from the White House spokesman, the leader of his parliament said that he was disgusting, and so on, we can see that Americans will never give Putin the title of peacemaker and let him win the Nobel Peace Prize. There is no possibility, and he will take various measures. Because now the initiative is not in Putin’s hands, the initiative is in Obama’s hands, and it is Obama, not Putin, who has the final say. Putin can only beat around the bush and say that you don’t want to fight. He can only persuade Obama not to fight, or exert pressure to really decide whether to fight or not. Who will win the Nobel Peace Prize in the end? Who will guide the outcome of the Syrian war? It is the Americans who have the final say, not the Russians, which can be judged.

　　Commenting: The fate of the Syrian government is decided in the ongoing negotiations on chemical weapons.

　　Moderator:

　　Another topic, let’s pay attention to Mr. Song. Today, the foreign ministers of the United States and Russia held a meeting in Geneva, which will be held in the next two days. It is said that the information leaked is not bad and promising. At the same time, however, Syrian President Bashar al-Assad had a saying that he accepted RIA Novosti and said very strongly that if you armed the opposition, I’m sorry, but I may not do anything about the transfer of chemical weapons. What does this sentence mean?

　　Song Xiaojun:

　　I think he is warning the United States and Israel not to push their luck. Putin handed you the steps, helped you down the steps, and I swept the ground under the steps. As a result, you have to give offensive weapons to the opposition, that is, the Syrian Free Army. Now it is the worst army to be beaten. It is not kind to do so, so it should be said. But in fact, Kerry and Lavrov must be laughing secretly, because everyone knows that this matter is very long. For example, in 2004, Gaddafi handed over chemical weapons, and Gaddafi’s chemical weapons were much less than those in Syria.

　　Expert opinion: Kerry and Lavrov "stole the fun" before the talks.

　　By 2011, when he was killed and shot down, his chemical weapon mustard gas was treated by 40%, and the chemical weapon raw materials were treated by 50%. This is a very long matter, and basically this matter is gone. In this case, the United States also knows that this matter is a face matter, which is Putin’s face and Obama’s face. As for whether this 1,000-ton chemical weapon can be disposed of quickly, everyone will forget it in the future. As soon as the heat of the two news cycles is over, everyone will ignore it. Other things, elections and other things. But it is a bit unkind to give weapons to the opposition at this time.

　　Moderator:

　　Of course, from Assad’s point of view, he must protect his own regime, but as you said, I am afraid that all parties, whether the United States and Russia or the US Congress, are a little snickered, which finally gives everyone a sigh of relief. Ok, our Global Sight will continue later.

　　Cctv news Recently, many places in Fujian have distributed epidemics. Recently, many places in Fujian have distributed epidemics. Fujian Big Data Co., Ltd. (hereinafter referred to as "Fujian Big Data") has implemented the work requirements of "fast, accurate, strict, practical and detailed" put forward by the provincial party committee, and leveraged big data to go all out to strengthen the information support force for epidemic prevention and control in the province, and help the province to carry out accurate epidemic prevention and scientific control.

As one of the core components of automobile, engine not only determines the quality of automobile, but also determines the temperament of automobile. Under the influence of manufacturers and media for many years, consumers generally understand what kind of output performance will be brought to the engine behind the parameters such as displacement, torque, horsepower and power. However, in the vehicle configuration table, the engine will have a label, engine cylinder diameter and stroke. What information is hidden behind these two parameters?

Influence of radius ratio on engine dynamic characteristics

????

Simply put, the cylinder diameter refers to the diameter of the cylinder piston (inner wall diameter), and the stroke refers to the distance from the retraction to the extension of the piston rod. We all know that engine power is basically determined by engine displacement, and engine displacement = π× square of cylinder radius× stroke× number of cylinders, so the product of cylinder diameter and stroke determines engine power.

?

Under the premise of constant displacement, engine cylinders can be designed into different combinations, which can be generally divided into three types: cylinder diameter > stroke, short stroke engine; Cylinder diameter = stroke, equal stroke engine; Cylinder diameter < stroke, long stroke engine. The ratio of cylinder diameter to stroke is called radius ratio, which is an important parameter to judge the high and low speed of the engine.

?

The design of short-stroke engine with large cylinder diameter will increase the engine area and occupy a larger space in the engine room, but relatively, the engine height will not be too high, so it can effectively reduce the focus of the whole vehicle and ensure high-speed stability and handling performance. In terms of power output, short-stroke engines generally have higher rotational speed, because after the stroke is shortened, the stroke that a single work pushes the piston will also be shortened, and the number of times of doing work in the same time will also increase accordingly, and the output power will be greater, with the disadvantage of low torsion difference.

?

The long-stroke engine is designed with a small cylinder diameter, so the engine occupies a small area, and the front of the engine can be designed to be shorter, giving space to the cab behind. However, the longer stroke leads to the higher height of the engine, which hinders the reduction of wind resistance and streamline modeling design, and the higher center of gravity is not conducive to high-speed handling performance. Generally, the engine with long stroke design will have a low speed of peak torque. Because the piston runs once in the cylinder for a long time, the dynamic acceleration is high, so the torque is easy to increase. The disadvantage is that the top speed is not high, and because of the long stroke, the jitter problem of the engine is obvious.

?

The performance of constant stroke engine is between short stroke engine and long stroke engine. Although the short-stroke engine has high speed and stable output, it has no advantage in spatial layout, so the equal-impact engine is a compromise method, which keeps a certain cylinder diameter and a certain stroke, for example, Subaru 2.0L FA20 engine cylinder diameter = stroke diameter = 86 mm.

?

Therefore, it can be seen that the longer the engine stroke, the greater the displacement of the engine, but if the stroke is too long, stability and bending performance should be considered, while the short-stroke engine has high speed, low vibration and stable operation, but the manufacturing cost will be higher. Therefore, at present, the cylinder diameter ratio of short-stroke engines is generally not more than 1.3: 1, and those that exceed 1.3: 1 are reinforced, and so are long-stroke engines.

Is it better to have a larger stroke or a larger cylinder diameter?

????

A good understanding of the relationship between cylinder diameter and stroke can explain why some cars reach the red line at 5000 rpm, and some cars still have no fuel cut at 8000 rpm. Even if the same brand has the same engine with the same displacement and different models, its speed will be different. So, what effect does the speed have on consumers?

?

From the performance point of view, the stability of high rotation output of short-stroke engine is king, the starting acceleration is not high, and the speed is its specialty. Of course, high speed certainly means high fuel consumption, because the piston runs up before a drop of oil is used up, so the engine with high speed has high fuel consumption and emissions, which is generally suitable for sports cars or sports cars.

Comparatively speaking, the long-stroke engine is more space-saving in design, and the layout in the engine compartment is more convenient and changeable. For car companies, even if a new model is introduced later, it can be easily adapted with a little optimization, so it is more popular, which is not necessarily a bad routine for consumers.

?

Short stroke, small reciprocating inertia of the engine, suitable for high rotation; On the contrary, long stroke, large engine inertia and good low torque. Therefore, long-stroke engines that are good at emitting large torque in low-speed areas are more suitable for vehicles that require higher traction but lower speed, such as off-road vehicles, SUVs, trucks and so on. This kind of long-stroke engine generally has good torque characteristics and good starting performance, and the long stroke makes the engine burn more fully, so the fuel consumption is less, so it is very suitable for ordinary people to use. Now many ordinary cars also use long-stroke engines.

?

With the development of science and technology, in order to save mold and design costs, some large companies use engines with the same diameter-to-diameter ratio for their sports cars, cars and off-road vehicles, that is, several engines with different displacement share the cylinder block, and only adjust the number of cylinders or ECU driving computer to meet the needs of different models. For example, Volkswagen does not name every engine with a displacement, but all engines that use a cylinder are called the same name, and the prefix of the name is the same. EA113 is the code name of the engine block. This series of engines have been used in the fifth generation GTI, Audi TTS, Passat B5 and other models of golf.

???

Yaston’s nodule

?

For Keyboard Man, it is the most basic skill to know the performance of the engine by looking at the parameters. It is impossible to determine the performance of the engine just by looking at the basic parameters such as displacement, torque and power of the engine. Cylinder diameter and stroke should also be considered as important information, which is also applicable to ordinary consumers.

There are many people who blindly look at the vehicle dynamic parameters when buying a car. In fact, the greater the value, the better the experience.

Next, look at the configuration. The BMW i4 is equipped with car networking, driving mode selection, remote control key, interior atmosphere light, traction control (ASR/TCS, etc.) and other configurations.

After reading this car, I believe you also have a general understanding. This level of models can often take into account the cost performance and practicality, and is often considered by most consumers as the first choice when buying a car.

I learned from Zhidian Travel that I have arrived at the store. The new car is built on CHN platform, with a length of over 5 meters and a wheelbase of over 3 meters, which is larger than the 001 with similar positioning, and the rear shape is similar. 12 will provide two power versions of single-motor two-wheel drive and dual-motor four-wheel drive, with a maximum battery life of 700 kilometers.

The staff of Aouita Experience Center said that Aouita 12 will start the test drive and make a small order on October 22, and will be officially listed on October 31, with an estimated starting price of around 300,000 yuan.

　　On May 24th, A shares fell into hot search again. At the close, the Shanghai Composite Index fell 2.41%, the Shenzhen Composite Index fell 3.34%, the Growth Enterprise Market Index fell 3.82%, and Kechuang 50 fell nearly 5%. A total of 4461 stocks fell and only 278 stocks rose.

　　Wind data shows that northbound funds sold 9.549 billion yuan in the whole day, and the single-day net sales reached a new high since March 15.

　　Why did A shares plummet? What do you think of the market outlook A number of fund companies interpret the performance of the market today.

　　Why did A shares plummet?

　　Bank of China Fund said that the main factors affecting the market today are as follows:

　　First of all, after a strong rebound in the early stage, the upward momentum of A shares gradually weakened. Since the bottom rebound of A-shares on April 26th, after three weeks of repair, the space for oversold rebound has basically been realized, and the oversold kinetic energy of A-shares is gradually weakening.

　　Secondly, the overseas interest rate hike cycle continues to strengthen, affecting market risk appetite. European Central Bank President Lagarde made it clear on May 23rd that the European Central Bank will decide to raise interest rates at the monetary policy meeting in July this year. At the same time, the Fed accepted more than $2 trillion in fixed-rate reverse repurchase for the first time, hitting a record high for three consecutive days. The excess liquidity and high inflationary pressure reflected by it may prompt the Fed to intensify policy tightening.

　　Third, today’s sharp adjustment of Hong Kong stocks and the sharp net outflow of funds from the north have affected the sentiment of A-share investors.

　　According to the Morgan Fund, with the control of the epidemic in Shanghai and the warm care of the policy, the temperature recovery of A shares has been more obvious since May. After accumulating a certain increase, the upward pressure on the market is greater, and it is not surprising that there is a staged callback. Kechuang 50, which had a good rise in the previous period, led the decline. First, there may be funds to settle some of the previous profits. Second, today, an innovative drug, White Horse, experienced a large decline as expected due to the research and development of new drugs, which increased market volatility.

　　ICBC Credit Suisse Fund said that the current overseas interest rate hike policy has been continuously strengthened, and the negative interpretation of the fundamentals and overseas situation in China has been extreme since this year. Since the Shanghai Composite Index broke through 3,100 points and rebounded at the bottom, the characteristics of the emotional game are still remarkable, and the index failed to break through when it approached 3,150 points three times. As a weather vane of funds, it has flowed out substantially in the past two days, which has suppressed the market participation sentiment to some extent.

　　How to look at the market outlook?

　　The Bank of China Fund believes that the most difficult period of the market may have passed, and it will be gradually repaired but the space is limited. On the one hand, the 429 Politburo meeting emphasized that "the epidemic should be prevented, the economy should be stabilized, and development should be safe", and the policy bottom has been formed. Recently, the central bank lowered the lower limit of mortgage interest rate and LPR interest rate, and the policy of steady growth has been gradually overweight. On the other hand, it is still necessary to observe the improvement of the following factors in the larger-scale rebound and even reversal of the market: first, the domestic epidemic situation has further improved; second, the steady growth policy has been further exerted and effective; third, the inflation in the United States has clearly dropped and the attitude of the Federal Reserve has turned to doves.

　　Morgan investment fund believes that looking forward to the future, the negative factors affecting the market in the early stage will be gradually eliminated, and A shares are expected to gradually bottom out. Yesterday, the National People’s Congress further deployed a package of measures to stabilize the economy, striving to push the economy back to the normal track and ensure that the economy operates within a reasonable range. The package of measures to stabilize the economy announced this time is not only timely, but also linked with relevant policies such as finance, finance, industry and supply chain, covering industries that were seriously affected in the early stage and key areas related to the national economy. It is expected that relevant rules will be implemented one after another to help the economy grow steadily.

　　According to the Morgan Stanley Fund, in this big environment, A shares may consolidate in the second half of the year under the marginal improvement of related factors. Investors can focus on the manufacturing industry whose predicament is reversed after the epidemic is controlled, non-essential consumer goods that benefit from economic recovery, and growth sectors with high certainty of industry development space and sufficient valuation digestion.

　　ICBC Credit Suisse Fund said that the current valuation of A shares is at the bottom of the market, the domestic and international environment is gradually improving, and the time when the market reaction is more intense may have passed. The the State Council executive meeting deployed a package of measures to stabilize the economy and decided to implement 33 measures in six aspects to further stabilize the basic economy. It is suggested that we should continue to pay attention to the infrastructure and real estate industry chain under the logic of "steady growth", the opportunity to repair the valuation of cyclical products under the logic of "inflation", and the growth sectors such as new energy power generation, consumer electronics and new energy vehicles with matching valuation and performance growth under the logic of "high prosperity".

　　CEIBS said that it is unlikely that the short-term market will directly enter the reverse trend. Because the current market has fully taken into account the impact of the epidemic, it is expected that the short-term market will still be dominated by shocks under the premise of the subsequent non-proliferation of geopolitical conflicts and other factors. Standing in the dimension of the whole year, we will continue to be optimistic about the new infrastructure areas with high growth and high certainty in the medium term.

Xinhua News Agency, Beijing, December 13 (Yang Yang) In early December, the 2023 China Entrepreneur Boao Forum kicked off on the shores of Qionghai, where many entrepreneurs gathered to discuss the new direction of industrial development and technological change, and to seek a new chapter of high-quality development.

During this forum, Landmap, a new energy brand under Dongfeng, did two things: it became the official designated car of the forum, providing high-quality car services for thousands of scholars and entrepreneurs, and comprehensively assisting the work of the forum; it held the 2023 Landmap Technology Day and the global launch conference of Landmap Chasing Light PHEV, showcasing the hard power of Landmap technology and products.

During the process, Lantu gained praise and recognition from guests and users by virtue of the comprehensive value of its products and strength. People saw the brand’s inheritance of Dongfeng Gene, which was released in 2020, and also saw its innovative measures that changed every time.

It’s not a good idea.Technology heats up, warms people’s hearts

When the northern country is in the cold winter, Boao, Hainan, is still wide and warm, and thousands of trees are competing. The 2023 Landmap Science and Technology Day is held here, which coincides with its theme – "Science and Technology Heating Up".

Technology is good and warms people’s hearts. Technology does not stay in cold numbers on paper, or gorgeous footnotes that decorate the facade. Technology should create value for users and truly empower their lives. From the technology day of Lantu, this point of view has been mentioned again and again, giving the "technology heating" a real touch.

Technology is heating up, and safety is the cornerstone. For a long time, Lantu regards safety as a "life infra". From vehicle technology to production and manufacturing, all requirements are strict and excellence.

Lantu creates "no dead ends in the whole car" safety protection

With the design concept of safety first, Lan Tu creates an ultra-high-strength cage-type cockpit body skeleton, which is not only developed according to the global super five-star standard, but also adopts 2000MPa integrated thermoforming laser welding door knocker, 2000MPa aluminum-silicon coated door anti-collision beam, through-type aluminum threshold reinforcement beam, TRB + Patch composite structure thermoforming A-pillar and other processes. This "rigid steel and iron bone "-like protection also allows Lan Tu to complete the 90-kilometer-per-hour super-beautiful standard rear-end collision test.

Technology is heating up and facing the future. At the Science and Technology Day, Landmap named its centralized SOA electronic and electrical architecture "Tianyuan Architecture". Lu Fang, CEO of Landmap Automotive, explained that Tianyuan Architecture integrates top-level wisdom into the hardware base to provide users with a different car experience than before, opening a new era of new energy!

How to be different from the past, the answer of Landmap is to let users participate in the customization of products through the "developer platform". This is also one of the keys for Landmap to build a "user-based technology enterprise". Landmap revealed that using the open 600 + service interfaces of Tianyuan Architecture, both Landmap users, software enthusiasts, and intelligent hardware partners can carry out scene creation and application development, making the car a fun and easy-to-use third space.

The product heats up, take care of it all

The 2023 Boao Forum for Chinese Entrepreneurs lasted for four days, and dozens of parallel forums and sub-forums were rich in content and splendid. Outside the venue, Lantu Dreamers and Lantu Chasers, as the designated vehicles of the forum, shuttled inside and outside the venue to provide quality travel services for guests, becoming a striking scenery.

On December 5th, many guests who participated in this forum were invited to participate in the "2023 Landmap Technology Day and Landmap Chasing PHEV Global Listing Conference" held that night. At the conference site, the beams of light shone, intertwined and changed, shining on the sharp and slender body of Landmap Chasing PHEV, shining in the expectant eyes of the audience.

At the press conference, Lu Fang, chief executive of Lantu Automobile, said that "the user says you can do it, and you are the user type". Wang Junjun, CTO of Lantu Automobile, said that "the technical man is not grandiose, but only focuses on solving the core problem".

Lantu Wang Junjun: "The technical man is not exaggerated, he only focuses on solving the core problem"

Shao Mingfeng, assistant to the general manager of Lantu Automotive Technology Co., Ltd., and the person in charge of Lantu Automotive Sales and Service Co., Ltd., made several "all-in-one adjustments", which became the climax of the entire conference. In his firm and confident statement, Lantu’s emphasis on user experience is also self-evident. The "Lanhai Power" carried by it is also the most worthy of attention.

Lantu Shao Mingfeng: "The user’s desire, chasing the light PHEV is all under control"

"Why is the brand upgraded and the experience degraded?" Faced with the current situation, Lantu took out the "Lanhai Power" hybrid technology, and the Lantu Chasing Light PHEV equipped with "Lanhai Power" also opened a "new era" of hybrid luxury cars.

Lan Tu is like this, constantly keeping the complexity to itself and the convenience to customers. This is also the confidence that Lan Tu can "take care of everything".

The brand is heating up to create a down-to-earth central enterprise

"Many of Landmap’s explorations are very down-to-earth, and they are what the car owners want, and they often think of going in front of us." Mr. Liu, the owner of Landmap FREE, said.

As Mr. Liu said, "grounding" is a major feature of this central enterprise. The so-called "grounding gas" is to think and think again from the perspective of users. In the words of Lu Fang, CEO of Lantu Automobile, it is "to make users feel that you can be trusted and relied on."

From a technical perspective, Landmap focuses on privacy and security that many people ignore. Although the application of intelligent elements throughout the vehicle, in order to avoid the data security problems that users worry about, Landmap has established national secret-level data protection. The process starts from the time the user places an order for the car to the whole life cycle of the car. "It can achieve privacy that no one can touch, no one can disturb, and no one can record. In addition, a physical privacy security switch has been added in the light chasing car," Wang Junjun said.

In terms of user relationship, as early as the 2023 Voyah Night user night held on August 19, Lantu showed its users a strong "affinity". Lantu executives and users formed a fleet of 400 Lantu vehicles to welcome users from all over the world at airports and train stations. That night, they gathered with more than 5,000 confidants from all over the world at the Lantu user night, completing a zero-distance co-creation and beautiful encounter. Before the Guangzhou Auto Show, 168 Lantu owners lit up the Guangzhou Tower at their own expense and called Lantu with the Guangzhou landmark, which also showed the two-way running between Lantu and users.

On the night of the release of the Landscape Chasing Light PHEV, the arrival of the star of the hit new drama "Queen of News", She Shiman, caused cheers. She Shiman turned into the recommendation officer of Chasing Light PHEV and recommended the new car to the guests inside and outside the venue: "Girls pay great attention to appearance, and the shape of the car is indeed very important to me. I think Chasing Light PHEV is the shape I like very much. It is elegant, atmospheric and full of aura.

This conference was particularly eye-catching due to the excellent performance of the chasing PHEV and the arrival of She Shiman. Many guests announced the grand occasion of the night in the circle of friends. Allowing users to "chase stars" on the spot is Lantu’s "retention benefit" for users.

In today’s auto market, car companies are no longer looking down on users from above, but they need to be down-to-earth and can play with users. Lan Tu explains with action: Central enterprises can do the same!

Lu Fang said that Landscape is a brand that shares weal and woe with users, beauty and beauty. In our understanding, the beautiful life drawn together with users is called Landscape.

After the listing of Landscape Chasing Light PHEV, next, I wonder what kind of beautiful story Landscape wants to draw with users?
