After the launch of MINIEV, it successfully opened up the blue ocean of mini pure electric vehicle market, but due to the low imitation threshold, many competitors appeared. In addition, after BYD and its birth, the design of front and rear double-row doors brought more practicability, further eroding the market share of Wuling Hongguang MINIEV.

In order to enhance its own market competitiveness, Wuling Hongguang MINIEV will launch the fourth-generation model, which not only adopts a design similar to Wuling Bingo, but also adds four-door versions. At present, the real pictures of the new car have been exposed. Let’s take a look.

The fourth generation Wuling Hongguang MINIEV has a relatively rounded appearance. Its front face style is similar to that of Wuling Binguo, and it is equipped with a large-area closed panel. Annular daytime running lights are added inside the headlight group, and the charging interface is set behind the front logo, which caters to the aesthetics of women.

The side is still the common four-wheel and four-corner shape of mini-cars to ensure the interior space, and a two-color body is adopted to enhance the sense of youth and fashion. In addition, the size of the lower hub is upgraded from 12 inches to 13 inches, and two styles of rim covers are provided. The style of the tail is also relatively simple. The ring taillight group echoes the front face, and the Wuling LOGO is continued. The reversing light and the width indicator light are moved to the bottom.

In addition to continuing to provide three-door and four-seat models, the new car also adds four-door and four-seat models to choose from. The dimensions of the two models are the same, and the mass of the latter is increased by 20 kg. In terms of body size, the length, width and height are 3256/1510/1578mm and the wheelbase is 2190mm, which is 192mm longer, 17mm wider, 36mm lower and 180mm longer than the current models. Although the performance of the second row space in the limited body may be average, it will be more convenient to get in and out of the back row.

In the car, the design layout of the fourth generation Wuling Hongguang MINIEV is also similar to that of Wuling Binguo. The interior color matching of brown and beige creates a sense of grade that is much higher than that of the current models. It is also equipped with a double suspended LCD instrument and a central control panel, and the air outlet of the air conditioner is decorated with silver material, which looks more fashionable.

In the power part, the new Wuling Hongguang MINIEV is equipped with a motor with a maximum power of 30 kW, which is consistent with the 2024 Youth Edition and the Advanced Edition. The maximum speed is 100km/h, and it is equipped with a group with a capacity of 16.2 kWh. The cruising range under CLTC conditions is 205 km. For reference, the 2024 Wuling Hongguang MINIEV is available in 120km, 170km and 215km endurance versions.

　　Go with negative "emphasis", or you will die if you don’t succeed.

　　Since the beginning of this year, it is an indisputable fact that Xpeng Motors’s competitiveness has declined among a number of new power brands, and it is under the competitive pressure of Weilai, Ideals and a number of new energy brands. Judging from the delivery results of new power brands in the first half of the year, Xpeng Motors lags far behind LI, Weilai, Zero Run and Extreme Krypton, and the sales of the above brands are all in.eightMore than ten thousand vehicles. Even Nezha cars.sixThe monthly sales volume is not as good as that of Xpeng Motors, but it is still in the first half of the year53769The result of this car is slightly ahead of Tucki.

　　Therefore, for Tucki at this time, there is an urgent need for a product with the right price, which can play and measure, and stand out in the market. TuckiMONA
M03It can be said that it took Xpeng Motors nearly four years to build the first intelligent pure electric hatchback coupe in China. Even at the press conference, He Xiaopeng stressed: "Tucki is willing to spend a little more time and cost to build a" nice and interesting "car for young people."

　　From the current point of view, TuckiMONA
M03It is still very powerful, with high originality, ultra-low wind resistance and perfect body proportion. Although the space and intelligent configuration have not been officially announced, according to the original agreement between Didi and Tucki, Didi will open the whole ecology for Xpeng Motors for the first time.

M03The performance will not be bad, and it is worth looking forward to.

　　At the same time, for the electric vehicle market,MONA
M03Could be subversive—15The price below 10,000 yuan can realize intelligent driving, and Tesla first achieved the fair-price intelligent driving model on the market. However, Tucki.MONA
M03In fact, the market segments in which they are located are also quite voluminous. The products of established car companies such as BYD, Changan and Geely have already formed a layout, and the price/performance ratio alone is not enough. It is also necessary to see whether more information officially announced later is enough to surprise people and ensure mass production delivery.

One thing that impresses me about this car is that it doesn’t make a fool of itself in this era. It really refunds money. The pricing before it was said was really a slot, but the speed at which people reduced their money by 30,000 yuan is really speechless. I will make an account for you. Before the top is equipped with dual motors, it will land 32.5 with insurance, return 10,000 JD.COM cards and 30,000 points. Plus this time, it will be 30,000 yuan, which will be combined inside and outside.

Secondly, at first, this car didn’t hold a press conference for several hours like an Internet company. Although there is Baidu behind it, it is also an Internet company, but fortunately, those slots on Baidu’s search engine are not available in this car at all. With Geely’s joint operation, I think the advantage is that all the highlights of this car don’t exist on PPT, and all the points are supported by facts, vehicles and other big names. Why are you far ahead of your friends? It’s better to say something.

Double-player word games are divided into three levels.

1. The first level of word games requires two players to stand on two numbers in a specified time, so that the sum of the two numbers is the number given on the blackboard.

2. The second level of the word game is to turn over the cards within a specified number of times, so that the two cards turned over in succession have the same pattern, and finally all the cards can be turned over to pass the customs (players need to remember the patterns on the cards turned over every time to pass the customs more easily).

3. The third level of the word game is that within the specified time, two players control the pen up and down, left and right, respectively, so that the pen is connected 1, 2, 3, 4, 5, 6, 7 until 27 in turn (it is not allowed to connect every other number, but must be connected in turn).

On August 31, the reporter learned from the Provincial Information Center that the Henan credit information sharing platform has realized data networking with more than 40 industries such as safety production, environmental protection and taxation, and monitored the status of credit subjects through online big data visualization analysis, realizing "every batch must be checked" and "everything must be checked".

Henan credit information sharing platform is one of the important contents of building a pilot province of social credit system and big data integration development in Henan. After the platform is networked, all departments and units can reward and punish credit subjects through online inquiry in the near future and system docking in the long term when using the platform to carry out administrative work. For example, when the transportation department handles the examination and approval of the business license, the staff members log on to the Henan credit information sharing platform and enter key information such as the name of the legal person of the transportation company, the unified social credit code, the organization code, etc., so as to inquire whether the parties belong to the object of rewards and punishments. For the parties who belong to the object of rewards and punishments, the platform will automatically list the types and times of red and black lists and the corresponding list of reward and punishment measures.

Before the end of this year, the data of Henan credit information sharing platform will be embedded in the "online" service process, which will be integrated with the data of Henan government service network to realize the whole process of joint rewards and punishments, such as automatic warning, automatic retrieval, automatic trigger, automatic implementation and automatic feedback. In other words, if a faithless person breaks his promise once, the result will be automatic restriction everywhere.

In accordance with the requirements for the construction of a pilot province integrating the national social credit system and big data, Henan should become an important information big data gathering and sharing center and development and application center in China, and take the lead in sketching out a multidimensional credit "genetic map" for five categories of subjects including government, enterprises, individuals, institutions and social organizations. The relevant person in charge of the Credit Department of the Provincial Development and Reform Commission said that in the future, personal credit will become the second "identity card", and trustworthy people can enjoy the benefits of renting a car and staying in a hotel without paying a deposit, while untrustworthy people may even have difficulty going out to take a taxi and shopping in a supermarket.

Welcome to car home, let’s explore the latest development of the national sixth Ruifeng M3. I believe many friends have some questions about the news that the price of Guoliu Ruifeng M3 model has been reduced by 30,000 yuan and the listing price of Jianghuai Ruifeng M3 1.5T National Sixth Edition. Don’t worry, next, I will interpret these key information for you in detail to enrich your knowledge base.

First of all, the reason behind the 30,000-yuan price reduction of Guoliu Ruifeng M3 model may be to enhance market competitiveness or respond to policy adjustment. The specific reasons need to be combined with market analysis and manufacturer strategy. For the common fault of Ruifeng M3, the lack of engine oil, we know that it may be caused by poor engine seal or failure to maintain it in time. Car owners must pay attention to regular inspection and maintenance.

Regarding JAC Ruifeng M3 extended version 1.8 national six model, it supports gas change, but it needs careful operation. After all, it can run 300 kilometers after gas change, which may depend on engine modification and service conditions. The launch of the 1.5T National Sixth Edition not only meets the higher emission standards, but also improves the power performance, providing consumers with better choices.

The official guide price of Jianghuai Ruifeng M3 1.5T National Sixth Edition is 838-94800 yuan, which indicates that it has been upgraded to a more environmentally friendly emission standard, and it also means that the price/performance ratio may be improved. If you are interested in vehicle parameters, Ruifeng M3 Sixth Edition has a body size of 4651x1765x1900mm and the powerful power of 1.8L inline 4-cylinder engine, which provides passengers with a comfortable ride experience.

Finally, the official guide price and configuration of the 2019 Ruifeng M3 are different, which meets the needs of different consumers. Whether it is a 5-seat or 7-seat layout, there are corresponding models to choose from. I hope this sharing can help you with the question of reducing the price of Guoliu Ruifeng M3 by 30,000. If you have any other questions, please feel free to consult.

Giant panda national park

Chengdu area

Chengdu area of Giant Panda National Park is located in the northwest of Chengdu Plain, involving Dujiangyan, Pengzhou, chongzhou city and Dayi counties, with an area of 1,459.48 square kilometers, including 1,145.01 square kilometers of core protected areas.

This area is a key corridor hub for gene exchange of giant panda populations in Qionglai Mountain and Minshan Mountain. The national first-class protected wild animals such as giant panda, snow leopard, takin, green-tailed pheasant and national first-class protected plants such as Davidia involucrata, clover and yew are recorded in the scope. According to the fourth national panda survey, there are 73 wild pandas in Chengdu area of Giant Panda National Park.

As an endemic species in China, the wild population of giant pandas is only distributed in Sichuan, Shaanxi and Gansu provinces, and the active area is less than 0.3% of the national territory. According to the fourth national giant panda survey report, there are only 1864 wild giant pandas in China, of which 80% are distributed in Sichuan.

In order to protect the authenticity and integrity of the natural ecosystem and explore a new model of ecological civilization construction that can be replicated and popularized, since 2017, the pilot system of the Giant Panda National Park has been launched in an all-round way, with the planning scope spanning Sichuan, Shaanxi and Gansu provinces. Among them, Chengdu area involves Dujiangyan City, Pengzhou City, chongzhou city City and Dayi County, covering an area of 1,459.48 square kilometers.

Looking at China, the national park system pilot is still in the exploration stage. How can Chengdu combine the deployment of the central government and the requirements of Sichuan with its own reality to protect the home of giant pandas? Chengdu has goals and rules. Focusing on the protection of giant pandas and biodiversity, and focusing on the main functions such as scientific research, public education, international exchanges, tourism and leisure, we will strive to establish an eco-civilized city model in which man and nature coexist harmoniously in the world.

At the end of August this year, four management and protection stations (Dujiangyan, Pengzhou, Chongzhou and Dayi) were listed in Chengdu area of Giant Panda National Park, and 28 management and protection stations were set up, and the management tentacles continued to extend downward. On this basis, Chengdu has initially established a three-level management system, which also means that Chengdu has entered a new stage in promoting the pilot system of giant panda national park.

How is the pilot going? Recently, reporters went to Dayi, Pengzhou and other places one after another to visit the construction of the Chengdu area of the Giant Panda National Park.

Entrance community

Dayi section will build a "Snow Mountain Town"

The infrastructure in Pengzhou section has been steadily advanced.

The entrance community of Giant Panda National Park is the core area that integrates the functions of panda conservation, popular science education, cultural display, logistics support and panda tourism.

Relying on the good resources of Xiling Snow Mountain, Xiling Town, Dayi County is planning the entrance community of Giant Panda National Park, where a distinctive "Snow Mountain Town" will be built. The person in charge of the project told the reporter that the project will closely follow the IP brand value of Xiling Snow Mountain, the spatial form of mountain settlements and the ecological characteristics of mountains and rivers, and have the functions of cultural sightseeing and leisure vacation, so as to create a tourist destination integrating mountain recreation, parent-child vacation, leisure entertainment, characteristic business and health vacation.

Dayi area of Giant Panda National Park involves 4 towns and 14 villages, and there are 26 wild giant pandas in the area, which is one of the closest distribution areas of wild giant pandas in Chengdu. With the goal of building a three-dimensional landscape painting park city, Pengzhou is planning to build the entrance community of Giant Panda National Park with high standards.

According to the plan, the core area of the entrance community will assume the core function of the panda theme according to the spatial structure of one master and two vice-masters, and Baoshan Leisure Area and Yufu Kangyang Area will make use of their existing advantages to form supporting functions. According to the person in charge of Pengzhou Yujiang Valley Tourist Area, a number of major cultural tourism projects have been packaged under the guidance of "Community Planning for the Entrance of Pengzhou Area of Giant Panda National Park".

At the same time, related supporting projects are also being promoted. At present, major infrastructure such as Pengzhou section of Chengdu-Wenzhou Expressway and rail transit in the Weihe River Valley have entered the stage of construction drawing design, and construction will start after the year. Relevant road pipe networks, greenway trails along the river and parking lots are also under planning.

defense mechanism

Improve the multi-governance mechanism of ecological protection

A New Framework of "Giant Panda Court"

At the end of July this year, the court of Chengdu District of Giant Panda National Park was officially listed, which opened the first practice of cross-regional centralized jurisdiction of environmental resources trials in Chengdu.

This is a professional court specially set up for the Giant Panda National Park. Through cross-regional centralized jurisdiction, it gives full play to the advantages of professional trials, focusing on environmental resources cases in Dujiangyan, Pengzhou, Chongzhou and Dayi, which belong to the Chengdu area of the Giant Panda National Park, further improving the multi-governance mechanism of ecological protection and building a new framework for judicial protection and co-governance of the Giant Panda National Park.

In addition to justice, scientific and technological means are also helping the protection of giant pandas. At present, an all-round ecological resources monitoring system has been established within the jurisdiction, and the construction of a wildlife monitoring database and an infrared camera monitoring real-time transmission system has been completed. Through technical means such as "looking from the sky, patrolling on the ground and comparing maps", the unified supervision of various ecological resources such as forests, wetlands, green spaces and wildlife in the park has been realized.

Co-construction and sharing

Building the Giant Panda National Park

Integrate into community development governance

In the first half of this year, a conservation area of giant panda habitat in the plateau collective forest in Dujiangyan City (hereinafter referred to as "conservation area") was established.

In terms of organizational system, the Protection Community Management Committee, headed by the main leaders of the "two committees" of the community, has been set up, and a patrol team for resource protection and comprehensive social management has been set up with 20 community representatives. In terms of management system, the "patrol management system" and "resource management and scientific research monitoring system" of protected communities have been improved, and the linkage mechanism of giant panda habitat protection has been established and improved. It is reported that since the establishment of the protected area, there has not been a case of poaching, deforestation, forest fire and other destruction of forest resources.

Dujiangyan City’s practice is only a microcosm of Chengdu’s integration of the construction of the Giant Panda National Park into community development and governance. Within the scope of the park area, some brand-new explorations have been practiced-

According to the person in charge of the Chengdu area of the Giant Panda National Park, Chengdu also encourages the indigenous residents to vigorously develop characteristic ecological industries such as bamboo and Chinese herbal medicines and the under-forest economy, and supports the surrounding communities of the Giant Panda National Park to moderately develop industries such as farmhouse leisure, accommodation and catering, and set up public welfare management and protection services in the protected areas to promote local residents’ employment and income, and share the natural ecological protection dividend.

Promote the coordinated development of the giant panda national park community with high quality, let the giant panda live in peace, and the picture of the national park where man and nature live in harmony is unfolding …

　　[Interpretation of car home’s fresh technology] With the development of electrification, more and more automobile manufacturers are considering replacing the traditional engine with motor drive. However, for plug-in hybrid SUV, the role of motor must be diversified, not only to drive the vehicle, but also to help the vehicle realize the four-wheel drive function and help the dynamic performance of the whole vehicle at all times. Based on the above requirements, Schaeffler put forward a solution, which is used for the two-speed electric drive axle with P4 frame. To put it bluntly, a motor is installed on the rear axle, but the highlight is that it is equipped with a two-speed reducer for this motor. At present, this product has been installed on Changan CS75 PHEV and (|). Today, let’s see if it is unnecessary to do so.

Read the full text in a few minutes:

1. Putting an electric drive axle on the rear axle can make the plug-in hybrid SUV realize the four-wheel drive function;

2. The Schaeffler two-speed electric drive axle has been mass-produced in Changan CS75 PHEV and WEY P8;

3. The natural special effects of the motor determine that it can use a reducer with a fixed speed ratio, but the fixed speed ratio will reduce the high-speed dynamic performance of the vehicle, and the bridge can not give more help to the vehicle in the four-wheel drive mode.

4. Schaeffler’s two-speed electric drive axle is equipped with a two-speed reducer, which brings better acceleration performance, more efficient economy and meets the complex mode of hybrid vehicles;

5. The modular design of Schaeffler electric drive axle can adapt to different models and platforms.

1. What is an electric drive axle?

　　When it comes to traditional fuel vehicles, everyone knows that there are engines and gearboxes, and when it comes to electric vehicles, there are motors and battery packs. However, electric drive axle seems to be a strange word. In fact, it is the name of a system. It can integrate motor, reducer, differential and electronic control system to realize the electrification of the drive system. According to the different installation positions, it is placed on the front axle or rear axle of the vehicle to realize the pure electric drive of the front wheel or rear wheel. It can also be applied to pure electric vehicles, hybrid or plug-in hybrid vehicles according to different vehicle types.

　　Using rear axle electric drive to realize four-wheel drive can save a lot of space and weight, make room for battery pack, and also save the cost of transfer case and transmission shaft. At present, this method of placing the electric drive axle on the rear axle is widely used in plug-in hybrid SUVs. For example, BYD Tang 100 adopts P034 frame, Changan CS75 PHEV adopts P134 frame, and Great Wall WEY P8 adopts P04 frame.

Second, does the motor need a two-speed reducer?

　　Changan CS75 PHEV and WEY P8 are equipped with Schaeffler two-speed parallel-axis electric drive axle. From the name, we can see the characteristics of this electric drive axle. One is that it has the function of shifting gears, and the other is that it adopts the layout of flat shaft.

　　During high-speed cruising, or overtaking, the pure electric vehicle is a little weak, and the motor keeps a high speed at this time, because it does not operate in the most efficient working range, and the efficiency of the motor is not as good as that of the internal combustion engine. At this time, you can add a gear to the reducer of the motor and pull the speed of the motor back to the constant torque area. In this way, the dynamic performance of the vehicle can be improved and the economy can be improved.

　　Seeing this, someone must say that since the two-speed reducer is so good, why not use pure electric vehicles? Because for most pure electric vehicles, the ultimate capacity is not the first. Moreover, pure electric vehicles can make up for the lack of fixed gear ratio reducer by selecting motors with high power density and high speed and excellent electronic control system.
