　(Reporter Shu Xiaotong from the News Center of Central Radio and Television General Station, Ya ‘an, Sichuan Province) Spring is warm and sunny, and when the flowers are in full bloom in Buzhoushan, the Central Radio and Television General Station led a team to go to Ya ‘an with Guangdong Jiushun Holding Group and Zhongzhu Holding Co., Ltd. to hold a discussion on the big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan", and to inspect the industry and big data industrial chain of the Economic Development Zone that has developed rapidly in Ya ‘an in recent years.

Yang Zongting, founder and chairman of the big data intelligent cultural tourism project of "Ancient Relics of Buzhoushan", introduced that more and more scholars and experts came to visit Buzhoushan, including China Academy of Sciences, China Academy of Social Sciences, National Astronomical Observatory, Central Party School, National Development and Reform Commission, Cambridge University, Columbia University, Stanford University, Washington University, etc., and CCTV News Center, Documentary Center and Central News Recording Film Studio also sent people to inspect and shoot. With the excavation of Sanxingdui cultural relics, more and more scholars believe that Kunlun Mountain and Buzhou Mountain are located in Ya ‘an, and Ya ‘an, Buzhou Mountain and Kunlun Mountain have become hot spots of public opinion.

Yang Zongting accompanied the executives of CCTV, Guangdong Jiushun Holdings Co., Ltd. and Zhongzhu Holdings Co., Ltd. to inspect Buzhoushan.

Zuo Yongzhong, president of Guangdong Jiushun Holdings Co., Ltd. introduced that "the ancient ruins of Buzhoushan" is a typical big data intelligent cultural tourism project, which is blank in China. Why do we choose Ya ‘an? Because Ya ‘an has excellent geographical environment and outstanding location advantages. It is 120 kilometers away from Chengdu and 115 kilometers away from Leshan, belonging to Chengdu’s "one-hour economic life circle". The project of "Ancient Relics of Buzhoushan" is located in Ya ‘an City, surrounded by Qingyi River in the west, north and east, and Zhougong River in the southwest, with Gongga Mountain in the west and Xiling Snow Mountain in the north. The vegetation on the mountain is good, the forest coverage rate is as high as 80% or more, and the clear spring gurgles all year round. The climate resources are superior, the air is fresh, and the maximum number of negative oxygen ions per cubic centimeter can reach 65830. Combined with the development of big data intelligent cultural tourism project, it will create a unique and original scenic spot with the theme of mountains and seas.

Geographically, Ya ‘an is a transitional zone between Sichuan Basin and Qinghai-Tibet Plateau. From a cultural point of view, Ya ‘an is a transitional zone between Han culture and Qiang and Tibetan culture. From the ecological point of view, Ya ‘an is a transitional zone between the central city and the natural ecological zone. In the past, Ya ‘an was the starting point of the ancient tea-horse road and an important node of the South Silk Road. Now, Ya ‘an has become an important intersection of the Sichuan-Tibet gateway transportation and logistics hub, the Chengdu-Chengdu Cultural Tourism Economic Belt, the Panxi Cultural Tourism Economic Belt and the Northwest Sichuan Cultural Tourism Economic Belt. Such a unique location advantage has greatly enhanced and broadened the development advantages of the big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan". Especially after the high-speed railway from Chengdu to Lhasa is opened to traffic, Ya ‘an will surely become the first choice for buying houses, living, leisure and vacation, and health care in different places in Kangzang area.

Signing ceremony for development and investment of big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan"

Yang Zongting, the initiator of the project, said that Zhougong Mountain was called Buzhoushan in ancient times, and it was recorded in the ancient Chinese historical document "Shan Hai Jing". Later, it became famous all over the world because Gong Gong was angry and could not touch Zhoushan. The "Dragon Cave" historical site recorded in China’s ancient geographical history "Taiping Universe" is located in the project area, which is the first of the eight scenic spots in Ya ‘an. There is Tianchi Lake at the top of Buzhou Mountain, which is called "Longhu Lake" by local people. There are many cliff inscriptions, eight diagrams stones, stone temples, stone beasts, stone squares and other relics in many places in the mountain. There is also an ancient scene of Longdong stone blooming on the mountain. Broken stone tablets and broken walls can be seen everywhere, with a strong historical and cultural atmosphere.

There are 5,000 mu of rest flower trees belonging to the rest family in Buzhou Mountain, and 3,000 mu in the scenic area, which were mistaken for wild jasmine by local people. The British Museum and the Royal Academy of Sciences have visited the country, and the conclusion is that the ancestral mountain of benzoin in ancient Persia spread to Persia and the whole Arabian Peninsula through the ancient Silk Road in Maiping six thousand years ago, and it grew and became a spice base for supplying the whole world. Nanshan, the president of the World Haiku Art Association, wrote "The Inscription of the Mountain of Not Being Surrounded" for the "Ancient Ruins of Not Being Surrounded", which wrote: The flower of Rest was born and raised in Sri Lanka 80,000 years ago, and the annual credit is granted in April, and the term lasts for a long time. Long-lasting fragrance, left a name in the world. Damascus, Persia, ruled the world in the Middle East, and benzoin was called the king, whose roots were traced back to Zhihu. Well, the ancestral court of benzoin incense should be inscribed with stones, so as to return the fragrance to elegance.

The ancestral hall of benzoin-the beautiful rest flower of Buzhou Mountain

Buzhou Mountain is called Shenshan Mountain, and there are still some ancient prehistoric plants such as Jin Sinan, Rest Flower, Emei Michelia, Dove Flower (Davidia involucrata), Taxus chinensis and Alsophila spinulosa. Jin Sinan, known as "Shenmu", has the functions of exorcising evil spirits, calming the nerves, expelling insects and exorcising evil spirits. It has been dedicated tribute wood for the imperial palace in past dynasties. There are countless existing animals and plants in Buzhou Mountain, such as God beast, God water, God fruit, God flower, God fish and so on. There are tens of thousands of rest flowers, yew, Jin Sinan, Emei smiling face and Davidia involucrata trees in the scenic spot. Besides, it is rich in natural green agricultural products, such as Mongolian Camellia, Tibetan tea, Tricholoma matsutake, mushrooms, yayu, yellow tangerine, loquat, cherry, bacon, jar meat, grass chicken, Duke of Zhou duck, yellow beef and so on.

Executives from Guangdong Jiushun Holdings Co., Ltd. and Zhongzhu Holdings Co., Ltd. visited Zhonghengtian SUV Automobile Factory.

Yang Zongting, the founder of Ya ‘an’s "Ancient Relics of Buzhoushan" project, loves collecting. Many of the cultural relics he collected in the local area over the past decades have attracted the amazement of experts and sinologists from Cambridge University in Britain, Harvard University in the United States and Columbia University, and some of them are even national treasures, such as the Yiji astrolabe of Buzhoushan, the remnant tablet of Buzhoushan and jade books. These discoveries have raised the importance of Buzhoushan to a higher position than Sanxingdui.

Join forces, Zuo Yongzhong and Yang Zongting shake hands in "the ancient ruins of Buzhoushan".

The folk song says, "Without Xi Wenju, there is no Bifeng Gorge". Known as the "Father of Bifengxia", Xi Wenju is also the president of China Metropolis Daily Research Association, the vice president of the World Chinese Newspaper Association, and the founder and president of Huaxi Dushi Bao. Xi Wenju thinks it is a great pity that Buzhoushan has such a good historical origin, such good natural science resources, and even the roots of Yijing and Taiji appeared here thousands of years ago, but Buzhoushan is idle in Ya ‘an. If the Bifengxia model is a bomb, then Buzhoushan is an atomic bomb! Recommended by CCTV, President Zuo Yongzhong specially hired Xi Wenju as the general consultant of the big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan".

Six wonders of the mountain: one is easy to change, the other is to rest in peace, the third is the sea of clouds, the fourth is the mountain spring, the fifth is the Buddha lamp, and the sixth is Gongga.

Zuo Yongzhong, president of Guangdong Jiushun Holdings Co., Ltd. said, "Bifeng Gorge is characterized by the natural landscape environment and private capital entering the tourism development, while Buzhou Mountain is a superb embodiment of the scientific and technological level and cultural self-confidence of the ancient Shu people 5,000 years ago, and it has real objects. This is the pioneer of human scientific and technological development, and its scientific and technological achievements stand in the forefront of all mankind, spanning 5,000 years. From the perspective of civilization, this is the forerunner of guiding human civilization, which is a super bright spot and even more distinctive than Sanxingdui. What really attracts people is to restore the mythical environment of Buzhoushan, let people enter the mythical world to experience enlightenment and reproduce the grand occasion of Shanhaijing civilization, which will become a unique tourist landmark in the development of China cultural tourism in the future. "

Yang Zongting accompanied the executives of CCTV, Guangdong Jiushun Holdings Co., Ltd. and Zhongzhu Holdings Co., Ltd. to inspect Buzhoushan.

The most important thing about the big data intelligent cultural tourism project of "the ancient ruins of Buzhoushan" is the opportunity advantage. Sanxingdui, the splendor of the ancient Shu kingdom, has made the world know China again, and know Buzhoushan again. Shanhaijing and Shanhaijing culture are getting hotter and hotter, which brings excellent business opportunities to the Buzhoushan project. Twenty years ago, Ya ‘an was famous for Bifeng Gorge, which became the model of western development and the engine of China tourism development. The successive appearance of these advantages has provided a profound cultural support system for the recreation industry of Wenlv, an ancient country with ancient ruins of Buzhoushan Mountain with mysterious cultural background of mountains and seas, and also created unprecedented development opportunities for the recreation industry. As a national demonstration city of forest tourism, Ya ‘an has been focusing on the benchmark positioning of "Lung of Abundance and Ecological Ya ‘an" in recent years, and is making great efforts to build a medical highland in western Sichuan. The launch and implementation of the big data intelligent recreation and holiday project of "Ancient Country with Ancient Relics of Buzhoushan" in Ya ‘an can be described as a golden opportunity.

Chairman Yang Zongting introduced that the infrastructure construction of the "Old Country with Ancient Relics of Buzhoushan" project is basically available, and the 15-kilometer scenic highway has been opened for operation; The planned 20 km tourist trail, 5 viewing platforms, 12 leisure pavilions and promenades are also under construction. Every weekend and holiday, the mountain is overcrowded, and the demand for catering and accommodation is in short supply. The scenic spot urgently needs to be expanded to meet the sightseeing needs of tourists.

With the cultural relics unearthed in Sanxingdui shaking the world, people pay attention to the mysterious ancient Shu country. It turns out that many stories recorded in the Classic of Mountains and Seas took place in Ya ‘an, especially the mythical figures such as Gong Gong, Zhuan Xu, Nuwa and Dayu all lived here. In addition, from the aspects of humanity, geography, landform, vegetation, animals and so on, it is consistent with the content described by Shan Hai Jing.

In Ya ‘an City, which is close to "the ancient ruins of Buzhoushan", the inspection representatives took a group photo.

"Ya ‘an Buzhoushan Ancient Relics Country" big data intelligent cultural tourism project is led by Yang Zongting and initiated by CCTV. Together with Guangdong Jiushun Holding Group Co., Ltd., it invests 3 billion yuan to jointly build a brand-new big data intelligent cultural tourism industry demonstration zone in Ya ‘an, which does not integrate Zhoushan mysterious cultural carnival, exhibition of Shanhaijing relics, cultural tourism and medical care. Three scenic spots, Zhuan Xu Valley, Nuwa Palace and Gonggong Tribe, are planned and designed for the project. These ancient buildings provide visitors with the magical landscape of primitive ancient Shu culture, and are entertaining around the fairy tale that Gonggong fought against Zhuan Xu and was angry with Gonggong, which forms the core scenic spot of the project theme.

The scenic spot of "the ancient ruins of Buzhoushan" also includes scenic spots and sightseeing routes such as Buzhoushan Shenshan Kangyang Sanatorium, Shanhaijing Creation Resort (seven-star), the annual Ya ‘an Buzhoushan Mystery Culture Carnival (cum Shanhaijing Culture Week), Buzhoushan Yiji Museum, National Western Landmark Observatory, Shanhaijing Museum, Shanhaijing Immersed Cultural Performance Center, etc. There are float parades and immersive performances of Shan Hai Jing in the three major theme scenic spots of "Ancient Relics of Buzhou Mountain", and visitors can intuitively see the scenes of Nu Wa, Zhuan Xu, Gonggong and tourists having fun together.

Zuo Yongzhong, president of Guangdong Jiushun Holdings Co., Ltd. said, "The Bifengxia model in Ya ‘an was born 20 years ago, and the world shook. Today’s Shanhaijing Theme Big Data Intelligent Travel Project will once again become the landmark of Ya ‘an online celebrity. ‘ The ancient ruins of buzhoushan ’ The Big Data Intelligent Recreation Project is a unique idea. Combining with the landform of the hills and seas described by the mountains and seas thousands of years ago, it will create a scenic spot with the theme culture of the mountains and seas as the main theme, and provide a unique theme park for the people of the whole country. This project will become a tourist landmark in Sichuan Province and a major tourist destination IP in China facing the ancient cultural theme of overseas tourists. The fundamental difference between this idea and the Bifengxia model is that it is full of mysterious cultural impacts and eyeball effects in addition to natural landscapes, bringing fresh tourist blood and a world-famous industrial chain of mountains and seas to Ya ‘an City, which is about to rise rapidly, and bringing a new wind to the cultural tourism industry in Sichuan Province. "

Sanxingdui culture has been popular all over the world, and there is a physical ancient cultural park in Ya ‘an-"the ancient ruins of Buzhoushan", which makes Ya ‘an rise against the trend and reproduces the tourism madness of Bifengxia mode 20 years ago. At this once-in-a-lifetime historical opportunity, the big data intelligent travel project of "the ancient ruins of Buzhoushan" landed in Ya ‘an, which will greatly enrich Ya ‘an’s cultural literacy, improve its cultural genes, become a unique platform for the cultural industry of Buzhoushan, bind tourism, sightseeing, science and technology, big data and health care together, launch a complete intelligent industrial chain, occupy the highland of ancient culture, and create a leading model for the development direction of China’s ancient cultural industry and big data intelligent travel.

CCTV led a delegation with Guangdong Jiushun Holding Group to visit the Digital Planning Museum of Ya ‘an Economic Development Zone.

At the invitation of the Ya ‘an Municipal Government, the Ya ‘an Economic Investigation Group, led by the Central Radio and Television General Station and jointly composed of Guangdong Jiushun Holding Group and Zhongzhu Holding Co., Ltd., visited key parks such as Ya ‘an Economic Development Zone, Yayun and Sports Center, visited Zhonghengtian off-road vehicle automobile factory, digital planning hall of Ya ‘an Economic Development Zone and supporting facilities for Olympic sports events, and reached a strategic cooperation agreement with the Foreign Affairs Bureau of Ya ‘an Economic Cooperation Bureau. In the conference hall of Ya ‘an Municipal Government, leaders from Municipal Economic and Trade Cooperation Foreign Affairs Bureau, Yucheng Economic and Trade Cooperation Foreign Affairs Bureau, Yucheng Natural Resources and Planning Bureau, and Gaobao Village of Zhougongshan officiated at the ceremony. Guangdong Jiushun Holding Group and Ya ‘an Zhougongshan Tianbao Tourism Co., Ltd. signed an investment and development agreement, and Guangdong Jiushun Holding Group and Zhongzhu Holding Co., Ltd. decided to jointly invest 3 billion yuan to build and develop the big data intelligent cultural tourism project of "No Ancient Ruins of Zhoushan".

Zuo Yongzhong, president of Guangdong Jiushun Holdings Co., Ltd. believes that the big data intelligent cultural tourism project of "No Ancient Ruins of Zhoushan" will rewrite Ya ‘an’s tourism history and cultural history. Through the project of "No Ancient Ruins of Zhoushan", people will enter Ya ‘an, experience Ya ‘an and examine another Ya ‘an different from the previous one. In this historical stage of economic and technological spurt growth, integrating historical elements of ancient Shu culture such as Sanxingdui, Maiping, Jinsha and Baodun will collide to form a brand-new cultural storm, which will cause a cultural phenomenon and make Ya ‘an a brand-new world-class cultural tourism highlight.

Because of the appearance of Sanxingdui, people have a new understanding of Sichuan and ancient Shu. In particular, many mysterious things revealed by China’s ancient book Shan Hai Jing appear in Sichuan and Ya ‘an today, especially the academic voices of Wawu Mountain as Kunlun Mountain and Zhougong Mountain as Buzhou Mountain are frequent, which makes people further eager to enter Ya ‘an and Buzhou Mountain, and opens the curtain of revealing the culture of Shan Hai Jing.

　　Sina Auto News The second-generation Changan Yidong, which was listed at the end of March, must have left the deepest impression on everyone, which is the brand-new exterior design and the space practicality that has continued from the first-generation model. Yidong’s market vitality is very strong, and it has been firmly occupying an important market position in the independent A-class car camp for many years. In fact, there are not many independent models that can adhere to the complete life cycle and realize the replacement. For Changan, if the replacement of Yidong only stays in the face value and space, it seems a bit "strong outside and hollow inside". This time, we were lucky enough to come to Chang ‘an Automotive Engineering Research Institute to perform a major operation on the second generation Yidong to see what progress it has made compared with the first generation in terms of driving quality.

　　Important chassis parts of two generations of Yidong vehicles were put on the scene. Zou Yi, a senior automobile engineer in Chang ‘an, emphatically introduced the differences in suspension structure between the two generations of mobile vehicles.

　　Although they are all rear suspensions in the form of torsion beam, the second generation of escape rear suspension adopts U-O Forming closed torsion beam rear suspension from German suppliers, which is more difficult in process. The biggest feature of the new rear suspension is that it reduces the weight by 20% compared with the traditional V-shaped torsion beam on the basis of ensuring the structural strength. The reduction of unsprung weight has obvious benefits for vehicle handling performance.

　　The improvement in technology is perceptible. Touching the inner side of the cross beam of the two-generation mobile rear suspension, you will find that the inner surface of the first-generation runaway has obvious burr feeling, while the inner side of the second-generation vehicle is obviously smoother, which feels like the effect after a steel plate is bent and butted end to end.

　　Facing the domestic road conditions, the hidden danger of the rear suspension of many models is not the fracture of the cross beam, but the stress fatigue is easy to form between the transverse and longitudinal beams. The welding area between the second-generation escape rear suspension beam and the longitudinal beam has been increased, and the official introduction shows that its reliability has been improved by 380%.

　　There are also differences in the arrangement of rear suspension shock absorbers between the two generations. We see that the shock absorber of the first generation model is located in front of the shock absorber spring and has a short length; The shock absorber of the second generation model is located behind the spring and has a long length. The purpose of adopting this vertical arrangement is to improve the efficiency of isolating vibration. After all, a longer shock absorber can provide a larger compression stroke and more adjustment space, thus improving the comfort of the rear row. In fact, if you pay attention, you will find that many luxury brands C-class cars and D-class cars also use this "super-long" shock absorber and arrangement. At present, this layout method has been used in Focus, Lectra 01 and other models, and the next generation of GM models will be equipped. Independent brands have also been gradually adopted, and the second generation of Yidong is one of them.

　　In order to improve the comfort, engineers have also optimized the bushing structure of the second-generation runaway suspension, and appropriately reduced the stiffness of the bushing, which can improve the filtering ability of the suspension to road vibration and help to isolate the road from fine bumps.

　　Changan engineer also demonstrated the process of adjusting the shock absorber for us. Engineers will put the designed shock absorber prototype on the bench for testing, and the bench will compress/expand the shock absorber at different speeds of 0.05, 0.1, 0.3, 0.6 and 1.2m/s for four times to simulate the daily road conditions. In this process, the system will generate the damping data of the shock absorber to optimize the shock absorber repeatedly. We see that there are throttle plates with different sizes and shapes in the shock absorber, each with different specifications.

　　For example, there are 28 different schemes of throttle plate in the above picture, and its working state and deformation can affect the flow of damping oil, and then affect the performance of shock absorber. Although the shock absorber does not directly reflect the "soft and hard" parts of a car suspension, these small differences can determine the final driving experience of a car. In fact, few domestic independent brands can independently develop, test and adjust shock absorbers like Changan, and most of them directly send the requirements to suppliers for them to do.

　　After the chassis suspension is developed, the vehicle will be handed over to KC test bench to verify the suspension and steering motion characteristics. The cost of the test-bed is about 20 million yuan, which can quantitatively simulate the load and wheel state parameters of the suspension under various road conditions or body postures. It takes 2 days for each prototype to be put on the shelf, collect data, and then complete a set of tests, in which the collection time of complete KC data takes 4 hours. Of course, it is impossible for a car to go through KC test only once, and the comprehensive performance of the chassis system needs to be adjusted and verified repeatedly. This process is extremely cumbersome.

　　For front-drive vehicles, vehicles tend to understeer during intense driving. It is impossible for a car to have no understeer at all, and engineers can only minimize this trend. In the second generation, the toe-in gradient of the wheel was optimized, and the relative positions of the internal and external mounting points of the steering gear were modified, which can slow down the trend of understeer to a certain extent, and then improve the handling stability of the vehicle in corners.

　　Chang ‘an has his own thoughts on driving DNA. For example, in terms of steering transmission ratio, the second generation of escape has not only pursued the feeling of comfort. Compared with the first generation model, its steering line angular transmission ratio is reduced from 3 laps to 2.83 laps. Most cars and SUV models on the market need about 2.8~3 laps from left to right, and sports-oriented models will take about 2.5 laps. From the change of the transmission ratio of the second-generation freewheeling steering, we can also see that Chang ‘an is not satisfied with "good driving", but should work hard in the direction of "fun+good driving".

　　For the adjustment of EPS electric power steering carried by the second generation Yidong, Changan uses a set of "robot" system that can quantitatively control the steering wheel angle and speed, and measure the steering wheel torque and body roll angle in real time. Engineers will set up different test forms, such as sine input, sweeping and catching up, to test the roll degree of the vehicle, the response speed of the steering wheel and the reliability of the steering motor respectively. It is worth mentioning that the second generation of escape has improved the power of EPS steering assist motor, so that the ease of use and reliability of the vehicle in extreme handling are more guaranteed.

　　In addition to the steering transmission ratio just mentioned, the steering force feel is also an important item in EPS adjustment. Engineers showed us two different forces used in the test, namely, extremely light and heavy. During the test drive, you can really feel the different performances of the vehicle under two kinds of dynamics. In the extremely light mode, the steering feel of the vehicle is almost zero, and it begins to respond when it touches the vehicle lightly; In the heavier mode, the steering power is obviously reduced, and the arm will be tired when rubbing the car and turning around at low speed. The engineer said that the steering power directly affects the communication between a car and the driver, and it is not advisable for the steering wheel to be too light or too heavy. Therefore, EPS should be adjusted in combination with factors such as vehicle positioning and suspension calibration, so as to achieve stability and give people some driving pleasure.

　　In April this year, the second generation Yidong achieved a braking performance of 35.6 meters in a public test, which is known to friends who know a little about cars-similar to many luxury brand sports-oriented models. This time, Changan engineers analyzed some reasons behind this achievement for us.

　　In this pie chart, we can see that the braking performance of a car excludes environmental factors, and the factors related to the vehicle itself include axle load, calipers, body posture, tires, ABS and friction materials. The second generation of escape is mainly optimized for the thermal stability of the brake system and the formula of the brake shoe.

　　Through CAE simulation analysis, the influence of different caliper fluid requirements on pedal stroke is simulated, and then the thermal stability of brake disc at different temperatures is simulated. Simulation analysis can greatly improve the efficiency of research and development, so that engineers can take as few detours as possible.

　　Of course, only simulation analysis is not enough. Chang ‘an also has its own braking system laboratory. For example, this is where the brake pedal strength and master cylinder pressure are tested. Why are the brake pedals of some models "soft" at the initial stage, and it is necessary to step on the vehicle deeply before the braking force is obviously released? This is the key issue. Generally speaking, there is a certain gap between the pedal and the master cylinder pressure, that is, the empty position of the brake pedal, but excessive defecation in the empty position will delay the release of braking force and even cause safety hazards. Although the second-generation Yidong 35.6-meter 100-kilometer braking performance is not directly related to fine adjustment, we can also see from here that Changan’s control over the details of driving experience is quite in place.

　　In terms of braking materials, the second generation Yidong has optimized the formula compared with the previous generation. The main improvement aspect is to control the thermal decay of the brake as much as possible when it is above 500℃, and reduce the sensitivity of the brake to pressure and temperature. In other words, in the future, car owners can use the brake pedal to control the speed more confidently when they are driving downhill on a mountain road for a long time, and the vehicle is not easy to "stop" because the temperature of the brake system is too high.

　　In the past, independent brands were still making efforts in terms of large space and high configuration, striving to win the favor of consumers with low prices and high allocation. With the domestic auto market becoming more and more mature, the car buyers have a deeper understanding of cars, and improving the internal quality of vehicles has become a hard bone that manufacturers have to chew. Two generations of Yidong, the first generation of models gain a foothold with high cost performance, and the second generation of models will inevitably improve their driving quality. You really can’t just look at the configuration list when buying a car in the future. If you don’t get in the car and drive it, it’s hard for you to know its inner beauty.

　　Cctv newsRussian President Vladimir Putin officially stated on the 6th local time that he will participate in the new Russian presidential election scheduled for March 2018 and strive for re-election.

　　All the Way

　　Since winning the Russian presidential election in 2000, Putin has served as three presidents and one prime minister. Some experts commented that after Putin took over the presidency, Russian society entered a new era. His road to the presidency is almost equal to Russia’s "road to revival". Let’s review Putin’s presidential road first.

　　Tough guy image

　　Over the past decade or so, Putin has won three presidential elections, and has maintained a very high popular support rate in China. Polls show that the Russian people think Putin is one of the most praiseworthy leaders in Russian history for hundreds of years.

　　On the international stage, Putin led Russia back to the center of the world stage. In 2007, he declared that he would "break the illusion of a unipolar world" at the Munich Security Conference, and in 2013, he published "Russia implores caution" in The New York Times, which was actually a warning. In March 2014, he made a speech on Crimea’s entry into Russia … … In the past decade, Putin has always been among the top three most influential people in the world.

　　Future challenges

　　In March this year, according to the Russian "Viewpoint" report, the poll data of the All-Russian Social Public Opinion Research Center showed that 74% of Russians indicated that they were prepared to vote for the current President Putin in the next presidential election, which was the highest in four years.Judging from the current situation, Putin’s chances of winning re-election are very high, but this does not mean that his presidential road will be smooth sailing.

　　Russia needs a strong leader. After the disintegration of the Soviet Union, Russians saw that without a strong leader like Putin, the country would not only be unable to develop, but most importantly, it would have no dignity internationally. In addition, Russia’s long-term economic structure that relies too much on military industry and resources also determines that centralized management forms are suitable for Russia’s development path.

　　Although there is little suspense in the outcome of Russia’s general election next year, the country’s development prospects are variable.If Putin successfully opens the "fourth term", can he "return you a miracle Russia" as people expect?

　　It is widely believed that if Putin is re-elected, his burden will not be light.. During his third presidency, Putin maintained domestic political and social stability, but encountered serious economic difficulties and the original economic and social development plan was not realized. This is not only influenced by the international economic crisis and western economic sanctions, but also caused by the unreasonable economic structure and inappropriate economic policies in Russia. In terms of foreign relations, Russia has gains and losses. Eurasian Economic Union was founded against the trend and developed difficultly. Relations with the West, especially with the United States, other NATO countries and European Union countries, have become more complicated due to the Ukrainian crisis, and the degree of military confrontation has been strengthened.If Putin is re-elected, it is bound to make some adjustments to domestic and foreign policies to face various challenges.

　　Wu Xuelan, Special Commentary of Wen Yi CCTV.

As a popular family car model, it is deeply loved by consumers. However, like any model, Volkswagen also has some shortcomings. This paper will list 20 fatal shortcomings of Volkswagen LaVida from many aspects, such as space comfort, reliability, maintenance and so on, to help consumers understand this model more comprehensively.

Although Volkswagen LaVida is relatively large in overall body size, the legroom of its rear passengers is relatively small. For consumers who need to ride in the back row frequently, the comfort may be affected to some extent.

The seat adjustment function of Volkswagen LaVida is relatively simple, lacking some advanced adjustment functions. This may limit the individual needs of passengers in terms of riding posture and comfort.

The storage space of Volkswagen LaVida is relatively small, especially in the trunk. This may limit the flexibility of passengers in carrying luggage and shopping, which is not practical enough.

Although the power of Volkswagen LaVida is not bad, its power performance may be average compared with some competitors. The power output during acceleration and climbing is relatively smooth, which may not satisfy the pursuit of driving pleasure and passion.

The suspension system of Volkswagen LaVida is relatively hard to adjust, which may affect the ride comfort, especially when dealing with potholes or bumpy roads.

The safety configuration of Volkswagen LaVida is relatively general, and it may lack some advanced safety functions and auxiliary systems, such as active brake assistance and blind spot monitoring. For consumers with high requirements for improving driving safety, they may need to consider other models.

Although Volkswagen LaVida has made some optimizations in engine technology and power transmission system, compared with some competitors of the same level, its fuel consumption may be slightly higher, which will increase the use cost.

The design of Volkswagen LaVida is relatively conservative, lacking unique design elements and fashion sense. If consumers have higher requirements on the personalization and attractiveness of vehicle appearance, Volkswagen LaVida may not be the best choice.

The rear seat function of Volkswagen LaVida is relatively simple and cannot be folded or adjusted, which limits the flexibility of passengers in storage space and ride comfort.

Although Volkswagen LaVida performs well in terms of stability and maneuverability, its maneuverability may be slightly inferior to that of some competitors. If consumers have higher requirements for vehicle handling performance, they may need to consider other models.

　　When it comes to electric vehicles, the first thing people think of is Tesla. This new generation of car company has quickly become a star in the automotive industry in more than a decade, and its stock market value has now exceeded that of Volkswagen and GM combined. Tesla has Model S, Wu has Model X, and the actively sinking Model 3 has made traditional car companies feel huge pressure, and it is quite unique. There are so many old rivers and lakes, is it true that no one can cure this menacing backlash? Porsche was the first to refuse.

　　The Taycan is Porsche’s answer. It’s been a while since the launch of the Mission E concept car and the launch of the Taycan, and the novelty of this Porsche electric car is gradually fading. But recently, the Taycan has finally come to Chinese consumers, giving us the opportunity to get up close and personal with it, and thus form a more intuitive understanding of the technical details.

　　800V电气系统是核心

　　保时捷Taycan采用纯电正向研发的思路打造，产品立项可以追溯到2011年。追求极致的保时捷工程师并没有选择奥迪e-tron那样的“油改电”模式，而是为Taycan开发了J1纯电专属平台，该平台未来还将应用于奥迪e-tron GT。此外，J1平台的宝贵研发经验将助力于打造更具兼容性的PPE平台，为保时捷电动车的后续发展奠定了基础。

　　保时捷为何大费周章将系统电压提升至800V？我们可以从高压输电原理中获得启示。在输电功率恒定的情况下，电压越高，电流越小，输电过程中因电流热效应造成的电能损耗就越小。Taycan的800V架构从根本上提升了三电系统的热管理水平，这对一台高性能电动车至关重要。同时，800V电压显著提升了充电效率，理想状态下充电功率可达270kW，这意味着仅需5分钟便可充入等效于WLTP 100km续航的电能。当然，充电功率还会受到充电基础设施的约束，为此保时捷将在2021年底前在国内建设超400根Turbo充电桩（800V、200kW）和超级充电桩（400V、120kW）。

　　性能强悍而持久

　　保时捷Taycan的在售车型包括4S、Turbo和Turbo S，均搭载前后双永磁同步电机，并以此实现了电动四驱。上述三款车型的0-100km/h加速时间分别为4.0s、3.2s和2.8s，对标全新911（992系列）的意味很强。对于电动车来说，实现不同量级的性能表现并不是什么难事，而在极限驾驶工况下打造稳定的性能才是最大的考验。

　　[car home New Car Launch] On March 20th, Kia China’s new energy strategy conference was officially opened. At the event site, Kia China released a medium-and long-term electrification blueprint, announcing a comprehensive transformation to an electrification brand, and accelerating and strengthening the investment in electrification products and services.

【 KIA EV6 GT 】

◆ KIA EV5 Concept Edition

　　In terms of appearance, as a concept model, its overall design is very avant-garde and exaggerated. Specifically, KIA EV5 Concept Edition follows KIA’s brand-new design concept "Opposites United", with a fully enclosed front grille and a light group with rich lines, which makes the front face of this car look sporty. At the same time, the car uses a large trapezoidal air intake with a blackened front bumper similar to matte material, which is young and fashionable.

　　From the side of the car body, the new car has a straight roof line, thus obtaining better head space inside the car. At the same time, the front and rear fenders slightly protrude from the car body and are full of muscle. In terms of the tail, the car adopts a similar double J-shaped taillight group, with the central Kia brand logo, which greatly improves the visual layering of this car.

　　In terms of interior, the center console of this car adopts a minimalist design style, with a penetrating integrated screen and a unique three-spoke multi-function steering wheel, which is very personalized. At the same time, the air conditioning outlet of this car adopts vertical narrow banner type, which is full of youthful feeling with the interior color matching of double color matching.

　　KIA EV5 concept car adopts borderless design, and integrates the shape of seat and console to enhance the feeling of space use and comfortable atmosphere. When the door is opened, the design of the rotating seat breaks the space barrier inside and outside the car, forming a brand-new layout. At the same time, the panoramic sunroof of this car is embedded with solar panels and supports free adjustment of lighting to meet the different needs and emotional States of users. It is worth mentioning that the light bridge is located on the panoramic skylight, which can be used to adjust the light in the whole internal space, and can also focus or diffuse the light by folding the light bridge.

　　At present, the official has not announced the specific parameters of this car, but the long-life version of CLTC has a cruising range of more than 700 kilometers and supports the function of external power supply (V2L). At the same time, the second generation remote control intelligent parking assistance system (RSPA2) will be applied to Kia cars listed in China for the first time. At the same time, the expressway driving assistance system (HDA2) with semi-automatic lane change, front/side/rear parking collision avoidance assistance (PCA) and parking distance warning (PDW) will also be equipped.

◆ Kia EV9 Concept Edition

　　　In terms of appearance, the car also follows Kia’s brand-new design concept "Opposites United", and adopts a distinctive vertical design. The special-shaped headlights on both sides and the matrix light source are very eye-catching, and also give the new car a certain sense of the future. In addition, the enclosed front grille also brings a tough style, and it is suspected that there is a vent design above the grille, which is helpful for heat dissipation and wind resistance.

　　　Coming to the side, unlike many new energy SUVs that emphasize smooth lines, Kia EV9 is more square and more like a fuel SUV. In addition, the new car will be equipped with a hidden door handle design, and the traditional rearview mirror will replace the electronic rearview mirror on the concept car. At the rear of the car, the shape of the taillights echoes the headlights from a distance, and outlines the muscular feeling of the tail. The rear windshield did not see the wiper, perhaps it was hidden inside the spoiler, and the details were very careful. In terms of size, this car has a body length of over 5000mm and a wheelbase of 3100mm.

　　　In terms of interior, this car uses white with low saturation and dark gray hue, and cooperates with many gun gray chrome-plated decorative pieces to create a simple and fashionable visual effect as a whole. At the same time, the car uses an unconventional steering wheel, and the connection with the steering column is located at six points of the steering wheel, and the rest remain suspended, which has a strong sense of science and technology. In addition, the large-size narrow-banner integrated screen and the unique hand pillow area have a prominent sense of fashion.

　　In terms of seat layout, KIA EV9 concept version adopts 2+2+2 seat layout, in which the second row of seats has massage function and the third row of seats can be electrically adjusted, which greatly improves the practicality. At the same time, thanks to the UWB digital key/digital grid/panoramic display screen/large-size HUD head-up display system and the installation of indoor atmosphere lights, EV9 will realize innovative interaction between drivers and vehicles.

　　In terms of power, the car provides a variety of power combinations, such as basic version/endurance version, single motor/dual motor, etc., and is equipped with an 800V high-voltage fast charging system. Through the fourth-generation battery and the second-generation battery management system, the charging speed is improved. Colleagues have also strengthened their cruising range performance. At the same time, the car will also be equipped with the highway automatic driving system (HDP), which is expected to achieve L3-level automatic driving. At the same time, EV9 comes standard with 10 airbags and is equipped with collision safety performance to improve safety. In addition, the KIA EV9 Concept Edition has a consignment performance of 2.5 tons, and is equipped with V2L external discharge function and a large-capacity front compartment up to 90L.

◆ Kia China’s medium and long-term electrification blueprint and product planning.

In addition, KIA will also cooperate with large dealer groups such as Simami, Jinlong, Xinhanma, Tongli, and Bradley to establish KIA City Store urban exhibition halls in the core business districts of first-and second-tier cities in China, such as Beijing, Shanghai, Guangzhou and Shenzhen. In the future, the official second-hand car replacement service will be launched. Kia will provide online evaluation, door-to-door inspection, door-to-door pick-up and delivery services for all brand owners, and Kia owners can also enjoy additional allowances and benefits.

◆ Edit comments

　　The new energy strategy conference of KIA China was full of dry goods, which not only released the product plan and the new energy operation plan in China in the next few years, but also brought two brand-new concept cars and a brand-new pure electric vehicle-KIA EV6 to consumers. It can be seen that Kia is determined to make a desperate effort in the domestic new energy market, which will further expand its target consumers and let Kia formally join the competition related to new energy vehicles.

　　It is worth mentioning that in recent years, China brands have gradually gained a firm foothold in the field of new energy, and have launched the latest research results in the fields of pure electricity and hybrid as well as flagship models with upward brand. It is foreseeable that in the future, with the addition of various KIA models, the domestic new energy market will be more lively and consumers’ choices will be more abundant. Let’s look forward to the answers given by the market. (Text/car home Zhouyi)

On February 7th, the Porsche Taycan has been well received overall since its launch in 2019, but its range has been criticized, which is slightly inferior to that of luxury electric vehicles of the same level. The 2025 Taycan will significantly improve its range and performance, while optimizing its appearance and technology configuration.

In terms of appearance, the new Taycan has not changed much, mainly including new LED headlights and improved front fenders. The high-end version will have a new light strip running through the rear of the car, printed with a glowing red "PORSCHE" logo, and the low-end model will also be available for a fee. The TurboS will also add decorative vents on either side of the rear bumper, which will not have heat dissipation but are said to improve aerodynamic performance.

All versions of the Taycan will be replaced with new batteries. The capacity of the standard version has been increased to 83.6kWh. The optional high-performance battery pack is optional on the Taycan and 4S models, and the Turbo model is standard, and the capacity has been increased to 97.0kWh. The new battery uses a chemical formula with a higher nickel content, which significantly improves the capacity while maintaining the same size as the old model. Thanks to this, the new high-performance battery pack is about 9kg lighter than the old model. Although the new car configuration has been improved, the TurboS has reduced the curb weight by about 15kg.

Charging speeds have also been increased, with peak power up to 320 kilowatts, provided that it is connected to a powerful enough 800-volt DC fast charging pile. Fast charging is possible even when the battery is at a low temperature. The new car will also come standard with a 150-kilowatt DC/DC converter, further enhancing charging speeds on the 400-volt network.

Thanks to improved powertrain efficiency and a larger battery capacity, the new car’s range has also been improved. According to the European WLTP standard, the rear-drive version of the Taycan with a high-performance battery pack can reach a maximum range of 677 kilometers, an increase of 174 kilometers compared with the old model; the TurboS’s range has been increased from 467 kilometers to 631 kilometers.

Another major hardware change is the new rear motor, which is lighter and more powerful than before. It still has a two-speed transmission design to improve efficiency at high speeds. The rear-drive version maintains peak power at 402 horsepower, but no longer needs to activate ejection mode to get full power. Porsche estimates its 0-60 mph acceleration time at 4.5 seconds, which is 0.6 seconds faster than the old rear-drive version.

The power of the TurboS is increased, but it needs to be unlocked gradually by the driver. The base output of the two motors is increased to 764 horsepower, and the new "overspeed" function of the SportChrono package can release an additional 93 horsepower in 10 seconds, which is activated by the button on the steering wheel driving mode selector. The ejection mode can further release the power, and the peak power is increased to 938 horsepower and the peak torque reaches 1100 Nm (the corresponding figures for the old TurboS are 750 horsepower and 1,050 Nm).

In addition to the base model and TurboS, the Taycan 4S and Taycan Turbo will also continue to be available, the specific parameters have not been announced yet. Both the Taycan sedan and the CrossTurismo wagon will be available in the United States, but the latter does not have a rear-drive version.

Other hardware upgrades include air suspension and adaptive shock absorbers as standard in all versions. The anti-roll bar system is still available as an option, but the 48-volt electrical system is replaced by a new electro-hydraulic ActiveRide system. As well as suppressing roll, the system compensates for pitches and nods during acceleration and braking, and provides a so-called "lean-in" feature that allows the Taycan to tilt slightly when cornering (similar features are already available on some Mercedes models). Unfortunately, the new Taycan still does not have a single-pedal driving mode, which Porsche believes will affect the purity of the driving experience.

The interior of the new car has changed very little. New filters have been added to the optional passenger side screen, which can only be seen from the passenger seat, allowing for legal video playback while driving. The digital dashboard has also been redesigned, and can now display a prediction of the maximum charging speed supported by the car based on the current battery condition. The user interface features a new generation of AppleCarPlay +, which can control functions such as air conditioning. Drivers using Porsche’s own navigation system can also plan detailed routes around charging stations and target battery levels.

The price of the new car has also risen, the entry-level rear drive Taycan is now priced at $101,395 (IT home note: currently about 731,000 yuan), Taycan4S is priced at $120,495 (currently about 869,000 yuan), TaycanTurbo is priced at $175,595 (currently about 1.266 million yuan), TaycanTurboS is priced at $210,995 (currently about 1.521 million yuan), the cheapest is $113,095 (currently about 815,000 yuan) Taycan4CrossTurismo, the new car from the summer delivery.
