Developing new seismic technology for structures to help high-rise buildings stand tall —— A record of Professor Lv Xilin, newly elected academician of China Academy of Engineering.

For 35 years, he devoted himself to the seismic research and teaching of building structures, and a new structural seismic technology was born from him and his team. He is actively committed to applying the latest seismic research results to engineering practice and escorting a number of major projects in China; He insisted on the road of international cooperation in seismic research and led the team to push China’s structural seismic research to the international stage …

He is Professor Lv Xilin, a newly-elected academician of China Academy of Engineering and an expert on earthquake resistance of building structures in Tongji University School of Civil Engineering. In November 2015, he won the "Science and Technology Progress Award" in ho leung ho lee foundation. In February 2017, he was awarded the Newmark Award by the American Society of Civil Engineers.  

Determined to do seismic research of buildings

This is a scene of the disaster area three days after the Wenchuan earthquake.

Here is a unit building in Qingchuan County, which was seriously affected by the disaster. The building is covered with numerous cracks. A burly middle-aged man is fearless, and the cat is the first to get in, looking at the damaged structure everywhere.

He is Professor Lv Xilin, the head of the expert group of Tongji University, the first batch of housing emergency assessment in Wenchuan earthquake-stricken areas of the Ministry of Housing and Urban-Rural Development. He volunteered at the first time after the disaster and rushed to the front line of earthquake relief.

Looking back more than 40 years ago, in 1976, when the Tangshan earthquake occurred, he was a sophomore in Xi ‘an Institute of Metallurgy and Architecture (now Xi ‘an University of Architecture and Technology), majoring in "Industrial and Civil Architecture". At that time, Xi’ an also had an obvious earthquake. "The earthquake caused so many houses to collapse in an instant and took so many living lives, which touched my heart very much." Lv Xilin recalled, "From then on, I was determined to go to graduate school and concentrate on seismic research of buildings."

After graduating from college, he wished to enter Tongji University, which has the highest strength in earthquake resistance in civil engineering in China, to study for a master’s degree in structural engineering. In March, 1982, he continued to study for a doctorate in structural engineering at Tongji University, under the guidance of Professor Zhu Bolong, a well-known expert from Tongji University. The topic of his thesis is the seismic research on a large number of masonry structures in China. He also became the first batch of doctoral students after China resumed the postgraduate enrollment system.

In December 1984, Lv Xilin successfully passed the defense of doctoral thesis and became the first doctoral student in structural engineering in Tongji University.

"There are still many unsolved problems in the field of building earthquake resistance, and there are still many unknown phenomena waiting for us to explore." Young Lv Xilin, with the enthusiasm of scientific exploration, embarked on the journey of seismic research of building structures. 

Play a good job in the new technology of structural earthquake resistance "combination boxing"

This is a building in Dujiangyan. In the middle of the first and second floors, a structural member with a length of about one meter can show its talents when a strong earthquake strikes. It absorbs and consumes the energy released by the earthquake, so that it no longer strongly impacts the house; Its seismic fortification intensity is increased from 7 degrees to 8 degrees. This is a new type of structural seismic device-"damper" installed on the H-shaped steel support, which comes from Lv Xilin’s team and has been widely used in the restoration and reconstruction project of Wenchuan earthquake-stricken area, the seismic safety project of national school buildings, and other important projects such as Shanghai Ganghui Square.

"Traditional reinforcement is generally to thicken the beams and columns of the building, which not only has a long construction period and high cost, but also shrinks the housing area." Professor Lv Xilin said that the adoption of new brace+damper technology not only greatly improved the seismic capacity of buildings, but also saved a lot of engineering time and cost.

In fact, the team played the "combination boxing" of structural earthquake resistance: "rubber bearing+sliding bearing+viscous damper". The "isolation bearing" is installed between the building foundation and the foundation. When the earthquake occurs, the bearing shakes, dissipates energy and reduces vibration, while the building on it is motionless, so it is soft and rigid. The flexible and innovative combined isolation and vibration reduction system has been successfully applied to major projects of Shanghai International Circuit and more than ten foreign construction projects.

He insisted that the research results should be closely combined with the actual project: "We are not seeking technology for technology’s sake, but we should fully consider how to make the seismic structure system more reasonable and safer, the construction easier and the project cost lower."

Team Lv Xilin pays close attention to the safety of complex high-rise buildings. Most of these over-code high-rise buildings are particularly complex in shape, changeable in internal space and ever-changing in structure, which poses great seismic challenges to their structures. Over the past 20 years, Professor Lv Xilin led the team to continue in-depth research and made new breakthroughs in the theories and methods related to seismic analysis and design of complex high-rise buildings. The results have been applied to the seismic design and performance evaluation of more than 50 major or key projects in China, such as Shanghai Tower and Shanghai World Financial Center.

The team’s technical achievement of "one lifting, two moving and three strengthening" to improve the seismic performance of existing buildings has also been successfully applied to the relocation and reconstruction of outstanding historical buildings such as Shanghai Concert Hall and Shanghai Jade Buddha Temple Daxiong Hall.

He often teaches students: "Don’t be bound by the existing seismic technology of structures, or even be bound and restricted by the existing codes." For more than 30 years, he led the team, constantly exploring, developing and breaking through the existing seismic technology of building structures, and won the second prize of national scientific and technological progress and the second prize of national technological invention …

As early as more than ten years ago, he began to pay attention to and introduced the concept of "recoverable earthquake-proof structure" for the first time in China. Since then, he has led the team to invest a lot of time in tackling key problems, and the results have attracted the attention of international peers.

"Teacher Lu’s high sensitivity to the new structural seismic technology, his accurate grasp of its future development direction, and his tenacious spirit of persisting in the identified fields all make our students admire and feel ashamed." His student Professor Li Peizhen lamented this.

In tackling key problems in scientific research, Lv Xilin never forgets to teach and guide students. "Earthquake resistance and disaster prevention is a public welfare undertaking, and we must have dedication." "The engineering anti-seismic technology is regional, and we must develop new technologies in combination with China’s actual situation." In recent years, many doctoral students he trained and supervised chose to work in Xinjiang, Northwest China, Southwest China and Northeast China when they graduated. 

Promote international cooperation in the field of earthquake engineering

Walking in Building B of the Civil Building where the Department of Structural Disaster Prevention and Mitigation Engineering is located, you can often see young students from abroad exchange and study here.

In April this year, Tongji University Joint Laboratory for International Cooperation in Earthquake Engineering successfully passed the acceptance demonstration organized by the Ministry of Education, and experts recognized its construction achievements.

In July 2015, the "Joint Laboratory for International Cooperation in Earthquake Engineering" was established in Tongji University, bringing together the strengths of China, the United States, Japan and Italy to jointly carry out research on major international frontier earthquake-resistant scientific issues. Lv Xilin is the director of the Academic Committee of the Joint Laboratory, which is also the fruit of his decades-long adherence to the road of international cooperation.

The internationalization characteristics of Tongji academic had a deep understanding during Lv Xilin’s study in Tongji Garden.

After staying in school after graduation, Lv Xilin took the initiative to go out and keep in close contact with international colleagues. Tokyo institute of technology, University of California, Berkeley, Italian European Earthquake Engineering Research Center and other internationally renowned earthquake engineering research centers have all formed friendly cooperation partners with him.

After the Wenchuan earthquake, Lv Xilin established the Guanghua Academic Forum in the field of earthquake engineering. In the past 10 years, the forum has been held for 8 times, and a group of colleagues from the field of earthquake engineering at home and abroad gathered in Tongji for each session to exchange the latest research progress.

In September 2011, Lv Xilin became the new editor-in-chief of the international academic journal "The Structural Design of Tall and Special Buildings". This is the first time that a China scholar has been the editor-in-chief of the magazine since it was founded more than 20 years ago. In 2017, he was awarded the Newmark Award by the American Society of Civil Engineers. Established in 1975, this prize is awarded once a year, and each time a scientist who has made outstanding contributions in the field of structural engineering and engineering mechanics is selected worldwide. Lv Xilin is the first China scholar to receive this honor.

He also actively encourages and subsidizes postgraduate students and doctoral students to boldly make presentations at international forums. His doctoral supervisor, Professor Ying Zhou from Tongji University School of Civil Engineering, felt deeply "benefited from this". During his doctoral studies, Ying Zhou had the opportunity to give an academic report in international forums. After staying in school, she went to Berkeley to carry out project cooperation, and grew up all the way on the academic road. Now she has become the vice chairman of the International Society for Disaster Reduction and Control, the winner of the National Natural Science Foundation’s outstanding youth fund, and the director of the structural disaster prevention and mitigation engineering department of Tongji University.

"We can proudly say that the scientific and technological level of earthquake resistance and disaster reduction in China has been ranked among the first corps after the United States and Japan, and the gap is narrowing. We are mainly lacking in the fineness of product manufacturing and earthquake research." Professor Lv Xilin said that the International Joint Laboratory focused on civil and infrastructure projects, major construction projects, long and long bridge structures, lifeline projects, long and long tunnel structures, deep-water foundations and large-scale energy facilities that can recover their functions after the earthquake. In the past three years, it has released 14 research topics to the world, and achieved results in discipline construction, talent training and introduction, international cooperation and collaborative innovation.

"Structural earthquake prevention and disaster reduction, there are still many things to do. I will stick to my original heart and continue to go in the direction we are looking for with the team. " Looking to the future, he is still full of confidence. (Ai Jiao)

 

China Seismological Network: The Hualien 6.9 earthquake in Taiwan is the biggest earthquake in China this year.

  According to the official measurement by China Seismological Network, an earthquake of magnitude 6.9 occurred in Hualien County, Taiwan (23.15 degrees north latitude and 121.30 degrees east longitude) at 14: 44 on September 18th with a focal depth of 10 kilometers.

  According to China Seismological Network, the Hualien earthquake with a magnitude of 6.9 and the Taiwan Province earthquake with a magnitude of 6.5 last night (September 17) were swarm activities in the same area, and the epicentres of the two earthquakes were about 14 kilometers apart. The earthquake caused a strong earthquake in Taiwan Province Island, and the earthquake was obvious in Fujian, Guangdong, Jiangsu, Shanghai and other coastal areas.

  In addition, China Seismological Network also pointed out that the Hualien 6.9 earthquake in Taiwan was the biggest earthquake in China this year.

  According to the earthquake information broadcasting robot, since January 1, 2022, there have been 533 earthquakes of magnitude 3 or above in China, including 388 earthquakes of magnitude 3.0 to 3.9, 105 earthquakes of magnitude 4.0 to 4.9, 30 earthquakes of magnitude 5.0 to 5.9, 10 earthquakes of magnitude 6.0 to 6.9, and 0 earthquakes of magnitude 7.0 or above. The largest earthquakes occurred in Menyuan County, Haibei Prefecture, Qinghai Province on January 8.

Canada held a gay pride parade, in which the Prime Minister and Syrian refugees participated.

Trudeau participated in the "Pride Parade". Oriental IC diagram

According to the British "Guardian" report, on July 3, local time, Toronto, Canada held a "pride parade" aimed at promoting gay equality and liberation, which is one of the largest "pride parades" in Canada.

Canadian Prime Minister Justin Trudeau appeared in the parade that day. A young man wearing a white vest beside him also attracted widespread media attention.

According to reports, this man is a Syrian refugee named Bashir McLeish. He is 29 years old and was originally an airline employee in Damascus. Bashir McLeish is a homosexual and HIV carrier.

Bashir McLeish (right)

He told the Canadian Broadcasting Corporation (CBC) that he was completely shocked when he found that the Canadian Prime Minister was with him in the parade.

"For me, the concept of’ pride parade’ is a dream in itself, and being able to participate in this parade is more like dreaming. As for being able to participate in this parade next to the Canadian Prime Minister, I have never dreamed of it in the wildest dream." He said.

According to the Guardian, in the middle of the parade, McLeish finally got up the courage to talk to Trudeau. He thanked Trudeau and the Canadian government for their decision to take in refugees. Trudeau said that his decision was based on the wishes of the Canadian people.

According to CBC, at the beginning of the civil war in Syria, the first destination where McLeish fled was Egypt. There, he returned to his old job and started the work of fuel coordination. However, his work unit refused to sign a labor remuneration contract with him, which led to his loss of his job. In addition, he was found to have HIV in 2014, and Egyptian law prohibits foreigners with HIV from working in Egypt, which makes his situation worse.

However, a Canadian-based NGO "Rainbow Silk Road" noticed him, and with the support of this organization, McLeish arrived in Canada in May this year and started a new life. "Rainbow Silk Road" focuses on helping sexual minorities (LGBT) from Syria get out of trouble.

According to the Guardian, after taking office at the end of 2015, Trudeau and his Liberal government announced that they would welcome Syrian refugees and said that they would provide assistance to the areas receiving refugees. At the same time, Trudeau also vigorously promoted the development of LGBT affirmative action after he took office.

In May this year, Canada announced the adoption of legislation to prohibit discrimination, insult and violence against transgender people. Anyone who publishes "hate speech" to transgender people based on gender will be punished by law.

Trudeau said at the time: "I sincerely believe that Canada can and must do more (in promoting affirmative action). This is not only for ourselves, but also for setting an example to the rest of the world. An open and free society is the greatest thing we can aspire to. "

In addition, according to the data of official website, the Canadian government, 28,640 Syrian refugees have arrived in Canada.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  The Ministry of Industry and Information Technology can be said to be a very authoritative official spy website. About half a year before the new car goes on the market, the new car declared by the car company to the Ministry of Industry and Information Technology will be publicized. Like the publicity of other national ministries and commissions, the publicity of the Ministry of Industry and Information Technology is also very rigorous and meticulous. That is to say, as long as the models are exposed in the Ministry of Industry and Information Technology, they are basically in mass production. Ok, let’s take a look at the new car catalogues published by the Ministry of Industry and Information Technology in recent batches, and see the new car situation that will be listed in 2020.

  Audi A4L

  Time to market: April 2020

  Highlights: the appearance has been greatly changed and new models have been added

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  As can be seen from the declaration drawing, the new car adopts the same latest design language as the overseas version in terms of appearance, and the hexagonal grille with a large mouth on the front face becomes flatter and wider, while the upper and lower sides of the grille are decorated with slender air inlets, and the left and right sides are connected with headlight groups with regular polygonal shapes. There are eye-catching grid LED light sources in the lighting groups, which still have strong recognition even if they are not lit.

  On the side of the car body, the new car basically maintains the overall line of the old model, but the waist line adopts a three-stage design that breaks in the middle, replacing the old one, which is more dynamic.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  In the rear part of the new car, the taillight area is mainly modified, and the internal light source becomes a grid corresponding to the front face. At the same time, there are chrome-plated decorative strips connected in the middle, which is more atmospheric with the rich chrome-plated decoration at the rear bumper.

  In terms of power, the new car is still equipped with a 2.0T medium, high and low power engine, with the maximum power reaching 252 HP, 190 HP and 150 HP respectively, which is basically consistent with the current one, but on this basis, the new car has decentralized the Quattro four-wheel drive system to a medium power version of 190 HP and 40TFSI, giving users more choices.

  The mid-term change of A4L has obviously increased the sense of sportiness from the front face, which runs counter to the luxury of the current models. Like A6L, it has started to take the sports route. As for whether the sales volume will increase after the official listing, let us wait and see.

  Audi Q3 Sportback

  Time to market: April 2020

  Highlight: the styling design of the coupe.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  As the coupe version of the new Q3, the new car continues the design language of the new Q3 as a whole, such as the same LED headlight group, hexagonal grille and S-line front enclosure. Q3 Sportback adopts a large-area hexagonal honeycomb grille, and the edge of the grille is surrounded by black lines. With the narrow and sharp headlights and the black elements in the fog lights on both sides below, it is full of sports atmosphere.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  As for the power part, the declared vehicle is equipped with 2.0T, with a maximum power of 162kW, which is expected to match the 7-speed powershift, and equipped with quattro four-wheel drive system. In addition, the official said that more power systems will be added to this product in the future. In addition, the new car will have two-wheel drive and four-wheel drive models for consumers to choose from.

  It was not long before BMW X2 was made in China, and its current sales volume was also suppressed by Q3. The next generation of Mercedes-Benz GLA did not continue its sports attributes, which means that almost no model in this market segment can be used to form a direct competitive relationship with Q3 Sportback. However, there are only 2.0T models in the power part at present. If you want to go further, you need to launch the 1.4T version as soon as possible.

  Lingke 06

  Time to market: or the first quarter of 2020

  Highlights: It is an entry-level SUV with a plug-in version.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  The front face design of Lectra 06 is different from that of 01 and 02 which have already been listed, but it is very similar to the Lectra 05 which has just appeared. In addition, the biggest difference between Lectra 06 and other known Lectra models is that this car comes from the same BMA platform as Geely ICON, not the CMA platform of Volvo XC40. The LECK 06 is smaller in size, with a length of 4340mm, a width of 1820mm, a height of 1625mm and a wheelbase of 2640mm, and its positioning is also lower.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  In terms of power, the fuel version will be equipped with a 1.5T three-cylinder engine, with a maximum power of 177 horsepower and a peak torque of 265 Nm, matching a 7-speed dual-clutch gearbox. The fuel consumption of the Ministry of Industry and Information Technology is 5.9L per 100 kilometers, and the PHEV version will be equipped with a 1.5T engine and motor combination, matching a ternary lithium battery pack. The comprehensive power is still unknown.

  Geely’s high-end brand Lectra has laid out three main products, 01, 02 and 03, as well as two derivative models, 01 PHEV and 03+. This year, Lectra plans to launch 10 brand-new products in China. 04 has confirmed that it will not be launched in the market, and 05 and 06 will be launched next. With the emergence of LECK 06 as an entry-level SUV, it can be seen that LECK’s product layout has explored the small SUV market and is ready to do a big job here. I believe that with the influence of the current LECK brand and the reputation of the model, the sales volume of 06 will not be too bad after listing.

  Saic Volkswagen Viloran Weiang

  Time to market: 2020

  Highlights: Volkswagen brand’s first commercialized MPV

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  The new car adopts Volkswagen’s latest family design language. The oversized mouth bent downward has a total of six thick chrome-plated strips, which is very domineering, while the front bumper part has five chrome-plated decorations on the left and right, which is in line with the popular through grille modeling. The visual impact of the whole front face is not small, which is in line with the preferences of Chinese people.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  In the rear part of the new car, a flat and slender C-shaped irregular polygon taillight is used, with a slender through chrome-plated strip connection inside, and a Volkswagen new car logo with letters below in the center of the chrome-plated strip, which has a good business temperament with the exquisite chrome-plated decoration at the rear bumper.

  In terms of power, the new car is equipped with a 2.0T engine with a maximum power of 220 HP, and the fuel consumption per 100 kilometers can be as low as 8.1 liters.

  In the domestic joint venture MPV market, Buick GL8 has been the world for many years. Although the price is more expensive than competing products, it still can’t stop selling well. However, Volkswagen brands have always paid insufficient attention to MPV, and there is only one domestic Touran L model. Will the launch of SAIC Volkswagen Viloran pose a threat to GL8? Let’s wait and see.

  Chang ‘an Ford Explorer

  Time to market: within 2020

  Highlights: the domestic version has been greatly changed and is more suitable for Chinese people’s preferences.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  Compared with the overseas version, the shape change of domestic explorers is quite obvious. Its front air intake grille adopts multi-banner air intake grille, and with sharp headlights on both sides, the whole vehicle looks more atmospheric and energetic. The thick bumper design at the top and bottom is also the core soul of the car, which highlights the visual experience of the hard-core SUV.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  The tail has not changed much, and it still looks simple. The design of the taillight is different from the imported version, especially with the plated decorative strip in the middle, which is more layered.

  In terms of power, the new car will be equipped with a 2.3T turbocharged engine of CAF488WQGR with a maximum power of 276 HP, which is expected to match the 10-speed automatic manual transmission and four-wheel drive system.

  Ford explorers got up early to catch a late episode. When the SUV exploded, the explorers were not made in China, and now they are late. This time, let’s see if the brand-new Changan Ford Explorer can give strength after listing. Ford also needs a flagship SUV product to cheer itself up and enhance the reputation of existing brands.

  Tucki P7

  Time to market: the second quarter of 2020

  Highlights: science fiction vehicle design

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  At the Guangzhou Auto Show in November, Tucki P7 just announced the pre-sale price (270,000-370,000 yuan after subsidy), which appeared in the new car declaration list of the Ministry of Industry and Information Technology. It can be seen from the information that the company name of the new car is still Haima Automobile Co., Ltd., and it should still adopt Haima qualification for production and sales.

  The new car still adopts the design language of split headlights announced at the auto show. The head and tail lights are all split, with low streamline lines, hidden door handles, body measurements of 4880/1896/1450mm and long wheelbase of 2998mm, which is very atmospheric and futuristic.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  Even if Tucki P7 takes the road of new energy vehicles, the pre-sale price has largely broken through the limit of its own brand cars. Such a high price, coupled with the label of the new power brand that makes consumers talk about color change now, will make the sales volume after listing really worrying in the future.

  Saic Volkswagen tuyue pure electricity

  Time to market: or early 2020

  Highlights: the battery life reaches 300km.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  In terms of appearance, the new car basically follows the design style of the fuel version, but the grille on the front part is filled with black bright decorative strips, which makes the grille basically completely sealed, in line with the consistent characteristics of electric vehicles.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  On the side and rear of the car, it is basically the same as the fuel version. Of course, the tail mark e-THARU indicates the identity of the new car electric car. In terms of body size, the new car has a circumference of 4453/1841/1632 mm and a wheelbase of 2680mm, which is basically consistent with the fuel version.

  Once listed, SAIC Volkswagen Tuyue has achieved good sales with the appearance of "Little Tuang". The launch of this pure electric version has met the needs of some consumers, which will further enrich the product pedigree and provide consumers who buy new energy SUVs with one more choice.

  Honda’s new UR-V

  Time to market: or the second quarter of next year

  Highlights: The front face has changed greatly, and there are two power versions.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  The new UR-V is a mid-term redesigned model, and the front face has changed greatly. The brand-new U-shaped large mouth front grille is painted in black, which is integrated with the headlights with the same black background design. The change of the tail is mainly due to the brand-new design of the internal cavity of the taillight group, and the thin chrome strip hook edge is added at the bottom of the taillight. As for power, the new car offers 1.5T and 2.0T displacement engines just like the current models.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  The most minor modified model, the biggest change of the new car focuses on the appearance, and the fine-tuned front face and tail make the whole car look more recognizable. UR-V and Crown Road are sister models, and their product strength is not much different, but the market sales of UR-V are not as good as Crown Road, the reason is that the design is softer and less domineering. The new UR-V looks more imposing than the old models by upgrading its appearance. In a word, the new UR-V of Dongfeng Honda is still worth looking forward to.

  Citroen C3L

  Time to market: 2020

  Highlights: High-site cross-border style

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  The shape of Citroen C3L is basically the same as that of the current C3-XR, and the headlights on both sides are connected with the penetrating chrome-plated middle net, which matches the oval air intake grille below, but it still looks a bit simple and honest, yes, this is French romance. The bumper is equipped with a black front lip, which is in line with the style of its crossover.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  The length, width and height of this car are 4505mm, 1748mm and 1513mm respectively, plus the wheelbase of 2655mm. In fact, this size is also very sufficient for domestic consumers. Although this car is an ordinary car, its chassis clearance from the ground can even reach the distance of SUV, which is superior to ordinary cars in terms of vehicle extensibility and vehicle passability.

  Although the height of the car body is great in practicality, the styling seems to have returned to the design level of French cars a few years ago. As for the market performance, it is better to give the answer to future consumers.

  Chang ‘an Lincoln aviator

  Time to market: or the fourth quarter of 2020

  Highlights: from CD6 rear-drive platform.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  In terms of styling, domestic aviators are basically the same as the imported models listed before, and the new car adopts the latest design language of the family, just like a scaled-down navigator.

A number of heavy-duty models are exposed. New cars that will be listed in 2020 will be the first to see.

  As synonymous with American luxury, Lincoln’s various SUVs have already captured the hearts of many consumers with their calm and atmospheric shapes. This time, as the second domestic model that Lincoln will launch, aviators will also join hands with adventurers to compete in the domestic luxury SUV market.

  Summary:There will be a lot of new cars announced by the Ministry of Industry and Information Technology in each issue. The above are just the key models selected. It can be seen that the new cars of joint venture brands are in a state of competition, and both the replacement and the small change are eye-catching. In the downturn of the auto market in 2019, manufacturers also know that in addition to the same environment, it is the best policy to rely on the hard power of products to make a breakthrough.

2020 Bugatti Veyron Car Quotation

Only one person can sit, and one tire is 160,000.

Bugai (||)ran Turio, referred to as Bugatti Vision GT, is the only one in the world and is currently in Los Angeles, USA. This car is not a production car, but a "super" for the track. Generally, a supercar can seat two people, but this car can only seat one person. Its body is made of carbon fiber, with exaggerated appearance, shark wings and the French flag on the detachable big tail. This car has many distinctive features, starting with the rearview mirror.

Mirrors are different. The rearview mirror of an ordinary car is lens-type, while the GT is camera-type, and the image is displayed on the center console. In fact, the rearview mirror of the future car should be like this, which can reduce blind spots. As we all know, the blind spot of the car is bigger than that of the car, and the blind spot of the truck is bigger than that of the SUV. If you use such a rearview mirror, you can eliminate literacy, but the cost is too high and it has not been popularized yet. I believe it will be possible in the future. Besides the rearview mirror, there are red things on the windshield and under the rearview mirror of the car. This is a quick-opening device for escape. If there is an accident on the track, the driver will not be trapped. In addition, there is a small window on the roof, which is also used to escape.

The steering wheel is unique and has the feeling of a spaceship. There are buttons on the steering wheel, such as start, wiper, flash, PN gear, and a Vion GT nameplate with Yamaguchi’s signature. This car was born for the track, so it uses a racing seat, a racing seat belt and the LOGO of Vision GT and Bugatti on the seat. These signs and signatures tell you.

A set of tires of Bugatti Veyron is about $40,000, which belongs to aviation grade like airplane tires. The tires were specially made by Michelin for Bugatti. The tires of Vision GT are Michelin, but the price is more expensive than Veyron. A set of tires costs 93,000 dollars, a tire costs more than 20,000 dollars, and a single tire is equivalent to 160,000 yuan. And there are only two sets in the world, and there is also one set at Bugatti headquarters. If the owner needs to replace the tire, he only needs to pay 80,000 euros, 20,000 euros for a tire, not including the wheel hub. The average family car is equivalent to the money of a tire. This car also needs maintenance from time to time. Basic maintenance includes: changing oil, cleaning car glass, adding glass water, checking tire pressure, etc. The cost is 20,000 US dollars. With a little maintenance, a family car will be gone.

This car has four independent remote controls. The height of the chassis can be directly operated by the remote control, and the track mode can be entered with one button. The low body can reduce the drag coefficient and make the car play its best performance. In track mode, the front bumper lip is about 4cm off the ground. Some people may think, how can such a low chassis drive on the road? Actually, this car is built for the track, so don’t worry.

The engine is the same as Bugatti, 8.0-liter W16 4 turbocharged, with a maximum horsepower of about 1,500 horses and a speed of 400 kilometers per hour. As for how much the car can accelerate in 100 kilometers and how fast it can run at the top speed, it has always been a mystery. The official didn’t really test it on the track, but only through a virtual simulator, with a top speed of 447 kilometers per hour. To get the real data, you have to go to the track and try several times. There is only one car in the world, and the owner has no intention of testing it to keep it mysterious.

A set of tires is worth $93,000 and a spare tire is worth  80,000. However, the car keys of this car are really ordinary, on the same level as ordinary (||)7 and (||). The biggest highlight of car keys is that they are too common.

How much is this car worth? The world’s only single-seat Bugatti Vision GT, worth $5.16 million to $18 million. What is this concept? It is equivalent to 20-70 (||) GTBs (US$ 256,550 per vehicle), equivalent to RMB 35.5-124 million. If sold to China, plus tariffs and miscellaneous fees is unthinkable.

Bugatti, you know, can only take one person, one tire is 160 thousand, and there are only two sets of tires. I hope this can help.
