To say that the biggest event in the recent car circle is the Shanghai Auto Show, I’m afraid, and the major car companies seem to be gearing up to "do a big job" at the Shanghai Auto Show. This time, the most impressive thing about Shanghai Auto Show is the performance of new energy vehicles. If we say that new energy vehicles appeared in the form of "supporting roles" at the auto show before, then this time, new energy vehicles have become well-deserved "protagonists". The LECK brand has also brought its brand-new product-LECK 08 to the fans. Different from other models in the Lectra family, Lectra 08 is equipped with a brand-new EM-P super extended-range electric scheme, which has an output power of over 400kW and a comprehensive cruising range of 1400km, and can intelligently switch working modes according to the current demand, and combines the extended-range and PHEV modes. It can be seen that Linke 08 is fully prepared to bring something "different" to the market, so what kind of technical highlights does it have? Let’s take a look.

The comprehensive battery life is over 1400KM, and the long distance is really worthwhile.

As a new energy vehicle, the cruising range is naturally an unavoidable topic, and the appearance of the Lexus 08 has really eliminated the anxiety of cruising for consumers. The brand-new EM-P super extended-range electric scheme carried by Link 08 makes the whole vehicle excellent in battery life. One engine, three gears, three motors and a huge flat battery pack together constitute the most exquisite electric four-wheel drive system. At the same time, the battery pack on the Lectra 08 has a capacity of 39.6kWh, which also makes its comprehensive battery life reach 1400km, which is quite outstanding.

Not only that, the pure battery life of the LECK 08 has also reached 245km, which can basically cover the five-day commute demand in the middle of the week, greatly reducing the car cost of consumers. On the other hand, the LEICK 08 supports a maximum of 85kW DC fast charging, and the charging time of 30-80% is only 28 minutes. In other words, you can complete 80% energy supplement in the time of eating a fast food and drinking a cup of coffee.

What’s more, the flat-panel battery pack of LEICK 08 adopts the CTP technology of battery body integration, which makes the chassis smoother and safer. At the same time, it also supports 3.3kW external discharge in terms of functionality, which can make our outdoor life "call" at any time.

Intelligent switching of working mode makes it easy to handle various demands.

The bright spot on the Lectra 08 is far more than that. The brand-new EM-P super extended-range electric scheme on the Lectra 08 has a powerful electric control system, which will decide whether to start the P4 motor of the rear axle and when to adopt parallel mode or extended-range mode according to the current demand and road conditions. Compared with the traditional extended-range technology, the Lectra 08 engine can directly drive the vehicle, avoiding the loss in the process of extended-range power transmission and improving the acceleration performance; However, for the hybrid vehicle with traditional single-gear DHT structure, the energy consumption control of the Lectra 08 is lower, and the driving experience is close to pure electricity, smoother and quieter. After all, pure electric vehicles can bring drivers a sense of ease and a quieter and lower-cost car experience that traditional fuel vehicles can’t match. The following figure shows the different mode schemes that Link 08 can provide according to 15 common driving conditions, showing its all-around degree. Of course, Link 08 can provide more than that.

In order to reduce energy consumption, the P4 motor on the rear axle of LINKE 08 also adopts the first domestic IDA (Intelligent Dynamic Activation) technology based on drive shaft decoupling, which can automatically disconnect when it is not needed to work, reducing the driving resistance while saving energy. At the same time, the P4 rear-drive motor based on IDA technology based on drive shaft decoupling can achieve a long-distance high-speed endurance increase of 50km, which can alleviate mileage anxiety to some extent. This is unheard of in the industry and is second to none.

Write at the end:

For consumers, new energy technology and related technical terms may seem obscure, but consumers’ demand for endurance, driving experience and acceleration performance is real. At this point, the LEEK 08 and its EM-P super extended-range electric scheme have not only achieved technological breakthroughs, but also won the recognition of consumers, which also makes us look forward to its market performance.

　　[car home Electric Vehicle Technology] won an order of 500,000 yuan before it went on the market, which is enough to show that Tesla MODEL 3 is hot, and even quite a few people are purely "blind" and have no idea what kind of car it is before booking. Recently, a blogger in a foreign forum leaked the maintenance manual of MODEL 3, so the body structure and materials of MODEL 3 were exposed, and what does this mean?

● MODEL 3 is not a simple miniature version of MODEL S?

　　Tesla showed a subversive change with traditional car companies. MODEL S and MODEL X designed by former Mazda designer Franz von Holzhausen have also been recognized by most people in design, but the taste of "traditional cars" on MODEL S and MODEL X seems to be slightly strong. In contrast, MODEL 3 is a product that is more in line with future trends.

　　MODEL 3′ s 100-kilometer acceleration is less than 6 seconds, and the 21700 lithium battery with higher energy density is used. The cruising range of the two versions is 354km and 499km respectively, and it can be seen from the 8 cameras and 12 radars arranged on the body that it has the basic hardware of Tesla Autopilot 2.0. It is only a set of software programs to realize the high-level autopilot function. Therefore, it is still very powerful from the configuration point of view.

● Why didn’t MODEL 3 adopt an all-aluminum body?

　　Body material seems to be a means for emerging car companies to distinguish themselves from traditional car companies in the concept of building cars. All-aluminum body is considered by many people as the lightweight trend of future cars. However, why did the latecomer MODEL 3 change the material use scheme of MODEL S and MODEL X and adopt the steel-aluminum mixed body structure?

　　Aluminum alloy is light. Compared with the traditional steel body, MODEL S and MODEL X have greatly reduced the weight, so the power and economy will be improved accordingly. Of course, you don’t have to worry that the all-aluminum body is not strong. The technology of high-strength aluminum alloy has long been very mature. Through structural design, its strength can fully meet the requirements of automobiles. However, high-strength aluminum alloy is expensive, which is more expensive in manufacturing and maintenance than traditional steel. Therefore, at present, the all-aluminum body appears more on the relatively high-priced vehicles such as Land Rover Range Rover, jaguar XF and F-PACE.

　　Aluminum alloy is not only expensive in material procurement, but also more complicated in automobile manufacturing. Due to the material characteristics of aluminum alloy itself, in order to ensure sufficient strength, it needs a variety of riveting and welding processes in body-in-white assembly, and the natural processing cost will also increase.

　　Manufacturing cost is the main reason why Tesla decided to switch to steel-aluminum hybrid body, so it can further explore the price of products to attract more consumers.. Of course, this can also eliminate some consumers’ small concerns-the late maintenance cost of all-aluminum body is relatively high. When the car body is damaged by collision, it is difficult to reshape the aluminum alloy material. If the operation is improper, the parts are likely to crack or even break. After the damaged aluminum alloy parts, if the sheet metal process cannot be adjusted well, they can only be replaced as a whole. In addition, aluminum alloy materials need special technology to weld. Therefore, the all-aluminum body means that the later maintenance cost may be higher.

● What kind of body does MODEL 3 use?

　　Lightweight and low cost, so how does Tesla do it? Yes, steel and aluminum alloy are mixed and used. The following is the latest exposed Tesla body structure.

　　MODEL 3 uses ultra-high strength steel in the body side rail, A-pillar, B-pillar, roof side rail and floor beam, obviously to ensure the strength of the body main frame and improve the passive safety of the vehicle. For example, when dealing with frontal and side collisions, MODEL 3 can resist the impact energy and ensure the living space of the passenger compartment.

　　It is precisely because of the 25% small-angle collision test that the big brother Tesla MODEL S has not been able to get the "excellent+"evaluation on IIHS. Can MODEL 3 achieve better results through such strengthening measures? We can look forward to it.

　　The aluminum alloy material is concentrated in the tail, which may be related to the weight distribution before and after MODEL 3. We know that MODEL 3 adopts the form of pure motor rear wheel drive, and the rear bearing is subjected to more weight load of the whole vehicle, so in order to balance the weight distribution before and after, it is more appropriate to use lighter aluminum alloy at the tail.

　　Although MODEL 3 uses a large area of steel, due to the size, the vehicle weight is much lighter than MODEL S, and the vehicle weight is controlled at about 1.6-1.7 tons. The combination of aluminum alloy and steel combines various factors such as cost, power, economy and safety.

-Tesla’s internal side pillar impact test video is as follows:

More exciting videos are all on the car home video platform.

　　Perhaps the steel-aluminum hybrid body is also a trend in the future. Judging from the latest Mercedes-Benz S-Class and Audi A8, their bodies are made up of a variety of materials, the most representative of which is Audi A8, whose steel content has changed from 8% of the previous generation to 40%. Due to the progress of steel materials, the yield strength of ultra-high strength steel can reach more than 1500MPa, which is more conducive to improving the passive safety of vehicles. In addition, if the vehicle main frame wants to achieve a certain structural strength, the weight of this ultra-high strength steel may not be heavier than that of aluminum alloy.

● What does Tesla rely on to build MODEL 3?

　　At present, the main factory producing Tesla MODEL 3 white body is Fremont factory in the United States, which was once a factory jointly built by GM and Toyota. In 2010, Tesla CEO Musk bought the base for only half the estimated price at that time (about $42 million). Therefore, it can be said that Fremont factory still has some production experience in building steel body in white.

　　After MODEL S and MODEL X established brand image and recognition for Tesla, Musk began to take the more civilian product MODEL 3. In the face of greater shipments in the future, Tesla’s new Gigafactory factory will also play a role in providing lithium-ion batteries.

Summary:

　　Perhaps for consumers, how much aluminum alloy and steel are used is not so important. We only care about whether it is safe enough, whether the acceleration is not strong enough, whether the later maintenance is cheap, and so on. Judging from the price and positioning of MODEL 3, it is believed that the use of steel-aluminum hybrid body can also be accepted by consumers, because the later maintenance cost will be more affordable. What’s more, with the progress of ultra-high strength steel materials, perhaps the steel-aluminum hybrid body is also a development trend in the future.

Arguably, backed by big trees, there is no shortage of funds, resources and technology enterprises, and the mix should not be too bad. But from a realistic point of view, superior birth does not mean that you can easily succeed. In the automobile industry, many emerging "rich second generation" automobile manufacturing enterprises in recent years have encountered certain challenges in the early stage. The ultra-Vietnamese car is no exception.

According to public data, since its listing in October last year, the sales volume of Extreme Yue 01 has been in three digits. Two months before listing, the sales volume of Extreme Yue 01 did show an upward trend. However, since then, the sales of Extreme Vietnam 01 have turned sharply. In February of this year, Extreme Yue 01 only sold 147 vehicles. In April this year, the sales volume of Extreme Yue 01 was 362 vehicles.

It should be pointed out that, with the help of electrification, the recognition of local high-end models in China has been increasing, and the popularity has even surpassed that of traditional luxury brands. At present, there are frequent electric SUV models positioned at 200,000-400,000, and the sales of many models have reached thousands or even more than 10,000. In contrast, the market performance of Extreme Yue 01 is somewhat dwarfed.

To put it bluntly, as a brand of cooperation between Baidu and Geely, it can be said that it has gathered almost all the prerequisites that new car-making forces dream of, such as capital, technology research and development, and manufacturing system.

Driven by the joint efforts of Geely and Baidu, the car-making project of Jidu Automobile, the predecessor of Jiyue Automobile, has advanced rapidly. In just one and a half years, the limited edition of ——ROBO-01 lunar exploration, the first model of Jidu automobile, was born. ROBO-01 turned into 01 after a year of turning around because of the qualification problem of building a car. At this time, it was only two and a half years since the establishment of Distance Concentration.

From the product point of view, the ultra-01 is also remarkable.

Let’s talk about origin first. Extreme Yue 01 is developed based on the vast architecture of Geely SEA, and it is a sister car with the latest pure electric products of brands such as Extreme Krypton 001, Volvo and Polar Star.

Let’s talk about design Jiyue 01 has won three design awards: 2023 Red Dot Award, 2023iF Design Award and 2022GOOD DESIGN Award.

But the most brilliant thing is the intelligent level of Extreme Yue 01.

It is reported that Extreme Yue Auto decided to be a vehicle-level operating system SOA when defining Extreme Yue 01, and integrated it with electronic and electrical EEA into an intelligent architecture JET to realize global, end/cloud integration.

Moreover, Extreme Yue is also the second manufacturer to mass-produce pure visual intelligent driving solutions after Tesla. Extreme Yue 01 adopts a "pure vision" scheme based on high-definition camera, millimeter-wave radar and ultrasonic radar, and comes standard with a "ROBO Drive" intelligent driving system, and can subscribe to the ROBO Drive Max advanced intelligent driving system for 12 months for free.

In addition, Extreme Yue 01 also deeply integrates the technical capabilities of ERNIE Bot, Apollo, Baidu Map and Xiaodi.

It is worth mentioning that the system of Extreme Vietnam 01 is updated very quickly. Less than 5 months after listing, Extreme Yue 01 has pushed OTA 5 times. The latest V1.4.0 version has upgraded 200+ functions, including OCC(Occupancy Network Technology) visualization effect, two-way integration of SIMO and ERNIE Bot model, etc.

In the view of Extreme Vietnam and Baidu, the intelligent level of Extreme Vietnam 01 comes from the first echelon in China. Li Yanhong, founder of Baidu, once said that "Jidu will lead the Tesla generation in autonomous driving technology".

Such hard-core product strength also gave great confidence to Xia Yiping, CEO of Jidu Automobile at that time. He once said: "My goal is to sell 10,000 units a month. There is really no need to worry about building a car now, but it doesn’t mean that you can sell it if you build it. " In addition, Xia Yiping also revealed that "in 2028, Jiji will have the ability to deliver 800,000 car robots throughout the year".

However, the market performance of Extreme Yue 01 did not develop according to the official expectation.

From the anecdotal point of view, an objective factor is the fierce market competition. At present, the medium and large SUV market where Extreme Yue 01 is located has gathered competitors such as its sister cars Krypton 001, Tucki G9 and Zhiji LS6, and there are also star models such as Tesla Model Y at the same price. Fierce market competition objectively hinders the difficulty of "breaking through" from the market.

On the other hand, the core advantage of Ji Yue 01′ s intelligent driving has not brought too strong attribute bonus. Even if the intelligent driving level of Extreme Yue 01 is excellent, it can only be applied in a few big cities at present. The nationwide opening of PPA is expected to wait until after the listing of Extreme Vietnam 07. However, Tucki, Weilai, and Huawei all have more brand-name intelligent driving systems than Jiyue.

In addition, due to the low ownership of Extreme Yue 01, the users who have experienced the extreme Yue intelligent driving system are also limited, and the advanced intelligent driving system has not directly stimulated sales.

In fact, as we all know, one of the important reasons for the sluggish sales of Extreme Yue 01 is the lack of popularity and low sense of existence.

"From April 2023 to September 2023, we didn’t publicize it for nearly half a year. It takes only seven months for users to know more about Extreme, and it takes only four months for Extreme 01 to go public. " Xia Yiping said.

In March of this year, Xia Yiping pointed the finger at marketing when reflecting on the reasons for the sluggish sales of Extreme Yue 01. "When a user enters the Extreme Yue store, the first question to think about is not that I want to buy a car, but what brand is it, which requires us to solve the problem."

According to reports, from January this year, Jiyue Automobile began to make a big change in the entire marketing and sales team, and it personally led the team to start the reform of marketing and sales. Since the end of March, both the UD- user development department at the marketing end and the UO- user operation department at the sales end have undergone personnel adjustment. Xia Yiping personally took charge of the marketing end UD- the head of the user development department; Andy.Gao from Tesla is the head of the sales UO- user operation department.

In addition to organizational changes, Xia Yiping believes that the sales methods need to be adjusted accordingly. "In the past, many stores attracted users with simple and rude preferential policies, and sold things wrong," Xia Yiping said. "Extreme Yue 01 wanted to sell experience instead of hardware."

Xia Yiping put forward new sales requirements after focusing on sales. "Users don’t have to buy a car, but they should know the brand when they leave." At the same time, they also increased the live broadcast to publicize intelligent selling points to attract scientific and technological people.

In addition, the soon-to-be-listed second model, the Extreme Yue 07, will also bring new increment to the Extreme Yue automobile. However, in the industry’s view, it will take some time for Jiyue to get out of the painful period.

July 1, 2022 is the 25th anniversary of Hong Kong’s return to the motherland. Today, 25 years ago, Hong Kong returned to the embrace of the motherland, washed away the century-old humiliation of the nation and completed an important step towards the complete reunification of the motherland. Since then, Hong Kong has been reintegrated into the national governance system and embarked on a broad road of complementary advantages and common development with the mainland of the motherland, opening a new historical era of "one country, two systems", "Hong Kong people ruling Hong Kong" and a high degree of autonomy.

Over the past 25 years, relying on the motherland, facing the world and benefiting from innovation, Hong Kong has been constantly shaping its own modern features. The practice of "one country, two systems" in Hong Kong, like a seedling, has thrived in the storm and produced fruitful results. Especially since the 18th National Congress of the Communist Party of China, General Secretary of the Supreme Leader and the CPC Central Committee have made a series of important expositions and major decision-making arrangements on "one country, two systems" and Hong Kong’s work from a strategic and overall perspective, so as to promote the cause of "one country, two systems" to gain new experience and achieve new development. With the strong support of the central government and the mainland of China, and with the joint efforts of the government of the Hong Kong Special Administrative Region and people from all walks of life in Hong Kong, Hong Kong’s economy has continued to flourish, its position as an international financial, shipping and trade center has been continuously consolidated, the democratic rights and freedoms enjoyed by Hong Kong residents in accordance with the law have been more fully guaranteed, and various undertakings have made great progress, writing a new legend under the Lion Mountain.

When the situation in Hong Kong was once grim, the CPC Central Committee with the Supreme Leader as the core assessed the situation, made a major decision to improve the central government’s exercise of comprehensive governance over the Special Administrative Region in accordance with the Constitution and the Basic Law, improve the relevant institutional mechanisms for the implementation of the Constitution and the Basic Law, promote the establishment and improvement of the legal system and implementation mechanism for safeguarding national security in the Special Administrative Region, formulate the Law of the People’s Republic of China (PRC) Special Administrative Region on Safeguarding National Security, improve the electoral system of the Hong Kong Special Administrative Region, implement the principle of "patriots ruling Hong Kong", and support the Special Administrative Region to improve the oath system for public officials. A series of measures to treat both the symptoms and the root causes have promoted a major turning point in the situation in Hong Kong from chaos to governance. Practice has fully proved that in order to ensure the steady and far-reaching practice of "one country, two systems", we must always adhere to the principle of "patriots ruling Hong Kong". This is related to national sovereignty, security, development interests and the fundamental principle of Hong Kong’s long-term prosperity and stability. Only by "ruling Hong Kong by patriots" can the central government’s overall governance power over the Special Administrative Region be effectively implemented, the constitutional order established by the Constitution and the Basic Law be effectively maintained, various deep-seated problems can be effectively solved, and Hong Kong can achieve long-term stability and make due contributions to the great rejuvenation of the Chinese nation.

Walking through the mud, you know that the avenue is precious; After experiencing wind and rain, I feel the sunshine is more beautiful. The extraordinary course of Hong Kong’s return to the motherland for 25 years fully proves that the implementation of "one country, two systems" is conducive to safeguarding the fundamental interests of the country, Hong Kong and the vast number of Hong Kong compatriots. General Secretary of the Supreme Leader profoundly pointed out: "In the past 25 years, despite many storms and challenges, the practice of’ one country, two systems’ in Hong Kong has achieved universally recognized success." Facing the future, the Central Committee will continue to unswervingly implement the principle of "one country, two systems". With the deepening of practice and the continuous improvement of the institutional system, the superiority of "one country, two systems" will be further demonstrated, and the practice of "one country, two systems" will surely be more stable and go further.

Qian Shan is in the same vein, and all waters are of the same origin. The fate of Hong Kong has always been closely linked with the motherland, and national development has always been the greatest support for Hong Kong’s development. Today’s motherland is highly open and changing with each passing day, which is enough to provide strong impetus for Hong Kong to increase its advantages, expand its space and solve difficult problems with its size and vitality. In particular, the country’s construction of a new development pattern, the promotion of the "Belt and Road", the deepening of Guangdong-Hong Kong-Macao Greater Bay Area’s construction, the implementation of the "Tenth Five-Year Plan" and the outline of long-term goals for 2035 have created new major opportunities for Hong Kong’s development. On the new journey, the central government will further improve the policy system to support the complementary and coordinated development of Hong Kong and the Mainland, promote the innovation of Guangdong-Hong Kong-Macao Greater Bay Area’s institutional mechanisms, pay attention to the unique role of Hong Kong in building the Belt and Road Initiative, improve policies and measures to facilitate Hong Kong residents’ study, employment, entrepreneurship and life in the Mainland, and improve various mechanisms for in-depth exchanges and cooperation between Hong Kong and the Mainland in various fields. Facts will continue to prove that as long as we adhere to the principle of "one country", make good use of the benefits of "two systems" and find a correct position in the overall situation of national development, Hong Kong will certainly be able to cultivate new advantages, play a new role and achieve new development, so that the development results will truly benefit the vast number of Hong Kong residents.

When the wind is good, it is when you sail, and you are rushing to the future. For Hong Kong, "one country, two systems" is the biggest advantage, and national reform and opening up is the biggest stage. In the process of national reform and opening up in the new era, Hong Kong has a special position and unique advantages and can play an irreplaceable role. This position and role will only be strengthened, not weakened. Nowadays, Hong Kong’s development is back on the right track, with people’s minds stable, determined and secure. "Seeking stability and development" is the mainstream public opinion, and "opening a new chapter for Hong Kong together" has become a strong consensus. At the critical period of governance and prosperity, Hong Kong’s unique advantages such as marketization, internationalization, rule of law, numerous talents, diverse cultures, advanced infrastructure and excellent business environment will be fully brought into play. Hong Kong compatriots are not only fully capable and wise to manage, build and develop Hong Kong well, but also able to continue to show their talents in national development and even on the world stage. On the new journey, the vast number of Hong Kong compatriots will continue to devote themselves to the cause of national reform and opening up with sincere patriotism and the spirit of being the first. Taking advantage of the situation and taking advantage of the situation will certainly promote Hong Kong’s better development in the overall situation of national development.

After 25 years of hurricane and rain, and 25 years of spring and autumn, Hong Kong has once again stood at a new starting point. General Secretary of the Supreme Leader stressed: "The central government’s determination to comprehensively and accurately implement the principle of’ one country, two systems’ has never wavered and will never change." Today’s Hong Kong has a more solid foundation than at any time in the past, which can better safeguard national sovereignty, security and development interests and maintain Hong Kong’s long-term prosperity and stability. At present, our country has entered a new journey of building a socialist modern country in an all-round way and marching towards the goal of the second century. In the grand journey of the great rejuvenation of the Chinese nation, Hong Kong has much to offer and will certainly do. We firmly believe that the vast number of Hong Kong compatriots will carry forward the glorious tradition of patriotism and love for Hong Kong, work hand in hand with the people of all ethnic groups throughout the country, go forward in rain or shine, and constantly create a new situation in the cause of "one country, two systems". Hong Kong will certainly be able to create new glories at a new starting point and add luster to the Chinese dream of realizing the great rejuvenation of the Chinese nation!
