『2018 modelXuan yi chun Dian』

　　The comprehensive cruising range of Xuanyi Pure Electric is 338km. According to the 2019 New Deal, it can get a subsidy of 18,000 yuan. However, according to the subsidy policy in 2018, the car can get more than 80,000 subsidies, with a difference of more than 60,000 yuan. At present, Dongfeng Nissan has not launched a sales strategy about Xuanyi Pure Electric. During the visit, some 4S stores in Guangzhou and Shijiazhuang did not have existing cars, and a 4S store in Beijing stopped selling until further notice.

Full text summary：

　　The landing of the New Deal in 2019 has brought new energy vehicles into the era of low subsidies. Many people predict that new vehicles will usher in a wave of price increases. However, through our visit, we found that the prices of new energy vehicles have not changed significantly, but the preferential margins of models in some regions have shrunk to varying degrees. Although Changan Automobile, BYD, and Great Wall Motor’s Euler brand have issued insurance plans, the time span is not long; Chery Automobile raises the guide price by releasing new year models. This "price increase" method is more clever and easier for consumers to accept.

　　It has been more than a week since the New Deal was launched, and most new energy vehicle companies have not announced their new sales strategies. After all, not every company wants to pay for the subsidy. What are these car companies waiting for? It may be the competitor’s action, and the latecomers can better find the balance between sales and profits. In the cold winter of the automobile market and the transition period of new energy vehicles to marketization, price increases are no different from risks! Next, we will continue to investigate the terminal sales of some popular new energy vehicles and the implementation of official price protection measures, so stay tuned.

For Shanghai Volkswagen Passat 2019, consumers generally think that it is a cost-effective and worthwhile model. This model has shown remarkable advantages in many aspects:

appearance design

The car body has been carefully upgraded, and its size has increased. The newly designed chrome alloy decoration makes the car body more atmospheric, and the lines are smooth, which outlines the dual charm of fashion and dynamic. The tail design is particularly attractive, and the ingenious layout of the hidden exhaust pipe and the letter sign below enhances the unique recognition of the vehicle.

power performance

In terms of power system, the 2019 Passat offers two power options: 1.4T and 2.0T. Among them, the 2.0T model is divided into high-end and low-end. It is particularly worth mentioning that the model equipped with DQ381 gearbox ensures the driving stability and ride comfort of the vehicle and meets the diversification of the driver’s power demand.

Comfortable configuration

The interior of the car is rich in configuration. The addition of panoramic sunroof gives passengers a wide field of vision, and the function of front heated seat provides extra comfort in cold season. The sunshade curtain installed on the rear window ensures privacy, while the active braking function provides additional protection for driving safety.

To sum up, Shanghai Volkswagen Passat 2019 has become an ideal choice for many car buyers with its excellent design, practical power and intimate configuration. If you are looking for a car that is both practical and quality, this car is definitely worth considering.

Within the budget of 150,000 yuan, Geely Xingyue L Zhiqing has rapidly become the new favorite of the family SUV market with its excellent comprehensive strength, and has become a high-profile online celebrity model. If we know its excellent performance and high cost performance earlier, it will become the focus of market recommendation. Now, let’s explore this amazing and well-deserved high-quality car together and unveil its mystery as a treasure-class product.

As another masterpiece of Geely automobile family, Xingyue L Zhiqing’s design deeply integrates the brand’s iconic straight waterfall net, with strong lines and strong business and sports atmosphere. The body is outlined with double waistlines, supplemented by exquisite chrome decoration, which gives the vehicle a sense of visual hierarchy and strength. The front face design is full and full of tension, and the clever use of chrome-plated elements further enhances the overall visual impact. The side contour is smooth, and the multi-spoke sports hub not only enhances the sports attributes of the vehicle, but also creates a stable and fashionable atmosphere. In the rear part, the penetrating taillights are simple and exquisite in design, which effectively improves the recognition and safety of driving at night.

On the power core, Xingyue L Zhiqing is equipped with an efficient 1.5T four-cylinder hybrid engine, matched with the advanced 3-speed DHTPro gearbox, and achieved excellent performance of fuel consumption as low as 4.0L/100km per 100 km, which is particularly prominent in the same class. It is particularly worth mentioning that its engine thermal efficiency is as high as 44.26%, which shows Geely’s profound accumulation and innovation strength in the field of energy saving and emission reduction technology.

Stepping into the car, the interior design of Xingyue L Zhiqing is also eye-catching. Three 12.3-inch high-definition large screens are patchwork, with Galaxy OS intelligent car system and Qualcomm Snapdragon 8155 chip, which brings users a silky operation experience and rich entertainment information enjoyment. The seat not only provides comfortable configurations such as ventilation, heating and memory functions, but also ensures sufficient seating space, so that even tall passengers can enjoy a spacious and comfortable ride. However, it is a pity that the co-pilot seat is not equipped with ventilation function, which may have a certain impact on the comfort of passengers in hot summer days.

In terms of endurance and fuel consumption, with its powerful battery pack and hybrid system, Xingyue L Zhiqing has achieved excellent performance with a comprehensive cruising range of up to 1300km, providing a solid guarantee for long-distance travel. At the same time, the fuel consumption level as low as 4.0L/100km also greatly reduces the cost of users’ cars, showing its excellent fuel economy.

In terms of intelligent technology, Xingyue L Zhiqing also performed well. Galaxy OS intelligent car system is not only rich in functions and convenient to operate, but also brings unprecedented intelligent car experience to users. However, it also brings some security risks, that is, drivers may be distracted by relying too much on screen operation during driving. Therefore, while enjoying the convenience brought by intelligent technology, we also need to pay attention to driving safety at all times.

Finally, although Xingyue L Zhiqing has excellent performance in charging and power consumption, due to its hybrid status, it has failed to enjoy the unique policy preferences of pure new energy vehicles, such as green license, which may become a factor for some potential consumers to consider. However, with its high cost performance, excellent fuel economy and comfortable driving experience, Xingyue L Zhiqing still occupies a place in the domestic medium-sized SUV market and has become the focus of many consumers. And this year’s new models are here, and 25 models of Xingyue have arrived at the store now. Go and test drive!

"Jinghua" shield machine, with a diameter of 16.07 meters, a length of 150 meters and a weight of 4,300 tons. Lying horizontally, it is even higher than five stories … It looks heavy, but it has high skills: it is a good hand at digging holes and a sharp weapon for tunnel construction, like an underground dragon, such as a "steel pangolin". The shield machine developed by Tiejian Heavy Industry, from running to leading technically, has become another "Made in China" business card after "China High Speed Rail".

Hunan Daily All-Media Reporter Cao Xian Correspondent Hu Qing

In Tongzhou District, Beijing, the west tunnel of the East Sixth Ring Road reconstruction project is under construction. On the ground, beijing-harbin railway got on the high-speed train and galloped by, but the passengers didn’t notice that a "steel behemoth" was steadily driving tens of meters underground.

On April 12, 2022, China’s largest diameter shield machine "Jinghua" successfully crossed the Jingha high-speed railway line. This behemoth plunges underground, causing no disturbance to the ground buildings, and controlling the surface settlement in millimeter level, creating a miracle of the construction of super-large diameter shield machines in China.

This "Jinghua" shield machine rolled off the production line in Changsha No.1 Industrial Park of China Railway Construction Heavy Industry Group Co., Ltd. on September 27th, 2020. Shield machine is known as "the king of construction machinery". China was once a zero foundation, and its technology and market were controlled by people. Nowadays, the domestic brand shield machine represented by China Railway Construction Heavy Industry has occupied two-thirds of the global market share.

Over the past 10 years, how did China shield machine strike back brilliantly?

1 "2 mm" see skill-

Buried in stealth, amazing years

Shield tunneling relies on many cutter heads embedded in the front circular cutter head. The cutter head rotates slowly, like a big mouth, and the cutter head is like a tooth, which "chews up" rocks and sand and transports them through the pipeline.

Shield construction is to dig tunnels under the ground, and there is no need to "open the belly" on the ground, which has little impact on road traffic. In the underground reconstruction part of Beijing East Sixth Ring Road Reconstruction Project, the tunnel shield construction section is about 7.4 kilometers long, and the excavation section size is six times that of the general subway tunnel.

"It is the first time in the world for a shield machine with such a large diameter to dig such a long distance at a time." Railway Construction Heavy Industry undertook the task of developing "Jinghua", and the R&D team faced unprecedented challenges.

The underground space environment is complex, and more than 50 risk sources are densely distributed on the ground. Super-large diameter, super-long distance, super-deep soil cover and super-sensitive environment, some authoritative people in the industry are worried: "Will domestic equipment work?"

Without two brushes, I can’t do it.

In the process of tunneling, the shield machine faces all kinds of interference caused by earth pressure, underground water pressure, mud in and out, and rocks in the way. The R&D team adopted a high-precision gas-liquid balance control technology, and an air cushion cabin was set behind the cutter head cabin, so that the pressure was indirectly transmitted instead of directly impacted. Figuratively speaking, it is the increase of pressure and exhaust; Sudden pressure drop, replenishing qi, and instantly eliminating pressure fluctuation.

"The underground’ movement’ is big, and what to do on the ground is not affected." Zhang Shuaikun, vice president of Railway Construction Heavy Industry Roadheader Research and Design Institute, said that during the excavation of Jinghua, the surface settlement was always controlled within 2 mm.

By June 1, the "Jinghua" had broken through 3,668 meters, and the excavation was more than half successful. In the meantime, a new record of 542 meters in a single month was created. "Whether it is size or technology application,’ Jinghua’ has reached the world’s leading level." Zhang Shuaikun said proudly.

On the network platform, the short video about "shield machine" has been viewed by millions of people. While enjoying the convenience of cars and subways passing through tunnels, people want to know why tunnels are dug quickly and well now.

In the 1950s, China put forward the plan to build a subway in Beijing first. The first phase of the 23.6-kilometer-long Beijing subway project took more than 10 years from construction to trial operation.

Before tunnel construction in our country, the traditional manual drilling and blasting method was used to drill, shoot and dig stone slag, which cost a lot of manpower, material resources and even life. "Compared with the current shield machine that digs hundreds of meters every month, at that time, it was greedy every day, and it could not dig dozens of meters in one month." He Qiping, the 58-year-old chief technology officer of China Railway Construction Heavy Industry, has worked as a tunnel for most of his life and experienced great changes in the industry. He said with deep feeling that it would take at least 100 years to build all subway lines in China at the same speed as that of Beijing Line 1. Because China has its own shield machine, the speed of subway construction has been accelerated for more than 60 years.

Compared with the predecessors in the industry, Zhang Shuaikun, born in 1980s, is lucky. His WeChat avatar is "Jinghua", and the blank space of the photo reads: Burying your head and sneaking, amazing years. These eight words have become the best annotation of the largest diameter shield machine made in China, and also a vivid portrayal of countless hard-working scientific researchers and industrial workers.

2 From "1" to "1000+"-

The "printing machine" of foreigners has become the "competitive machine" of China people.

Seen from the satellite perspective, the super factory of Tiejian Heavy Industry in Changsha, Hunan Province is a shining new industrial landmark.

Ten years before the birth of "Jinghua", Railway Construction Heavy Industry produced the first EPB shield machine named "Pioneer 19".

"Pioneer" broke the game in one fell swoop. "Let the’ foreign shield’ with an average selling price of about 150 million yuan quickly reduce its price by 30% in China." Liu Feixiang, Party Secretary and Chairman of Tiejian Heavy Industry, said.

In the 1990s, China imported shield machines from abroad for the construction of large-scale tunnel projects. Wu Min, vice president of Railway Construction Heavy Industry Roadheader Research and Design Institute, used to drive foreign equipment in tunnel construction units, and he often wondered "when can the domestic shield machine be used".

Foreign shield machines are expensive to sell and the service is more expensive. Foreign companies hold key technologies in their hands, charge high service fees, wait until working days to solve problems, and often refuse to accept the rectification and optimization suggestions of domestic contractors.

The rapid development of China is changing with each passing day. The high-speed rail and subway network are accessible, and water conservancy and mine construction are speeding up. Large-scale engineering equipment like shield machine is too important.

You can’t always be led by foreigners. In 2008, Tiejian Heavy Industry decided to specialize in customized underground engineering equipment.

Supported by the "863" project of the Ministry of Science and Technology, in 2012, China Railway Construction Heavy Industry launched an attack on the first domestic rock tunnel boring machine (TBM). Different from the shield machine that eats soft rock and gravel, the rock tunnel boring machine takes hard rock as the "next meal", which is also the weak link of the autonomy and localization of tunnel boring equipment in China.

Knowing this news, Wu Min gave up his job with higher income at that time and devoted himself to the development of the first domestic TBM.

From scratch, grope forward. For twenty or thirty big parts such as cutterhead, shield, main beam support and propulsion, a research team is set up for each part. Every data is accounted for over and over again, and it is pushed over and over again. More than 3,000 mechanical drawings have been audited.

At the end of 2014, the first domestic open TBM was rolled off the assembly line of China Railway Construction Heavy Industry. In participating in the construction of water supply project of Jilin Province, the highest monthly footage of this TBM reached 1,209.8 meters, and the bid was completed more than one year ahead of schedule, leaving the foreign brands that competed in the same field and ranked first in the world at that time far behind. "Very uplifting!" Wu Min is quite proud of this product.

Today, there are 40 shield machine production lines in Changsha No.1 and No.2 Industrial Parks of Railway Construction Heavy Industry, which has become the largest underground engineering equipment manufacturing base in the world. Over the past 10 years, more than 1,000 roadheader machines have been sent from here. The shield machine, once regarded as a "printing machine" by foreigners, has now become a "competitive machine" for China people.

Great country heavy weapon serves great country project. The western water conservancy project, with a maximum buried depth of 2268 meters, is all over the altered rock belt. The variable diameter open TBM solves the "stuck machine" problem that plagues the world excavation industry and successfully breaks through the barrier. In the Pearl River Mouth Tunnel of Shenjiang Railway, "Shenjiang No.1" advanced to the depth of 106 meters, helping to build a half-hour living circle in Guangdong-Hong Kong-Macao Greater Bay Area …

3 From "Apprentice" to "Teacher"-

China equipment accelerates the equipment world.

In the early summer, on the west bank of Xiangjiang River in Changsha City, the super-large diameter shield machine "Xingsheng" is being debugged, and the trip across Xiangjiang River will be started soon, which will help alleviate the traffic bottleneck in the central city of Changsha.

From Beijing to Changsha, Railway Construction Heavy Industry has developed 6 sets of shield machines with super-large diameter of 15 meters and above. The core technology of shield machine in China has become more and more mature and powerful.

Shield machine integrates advanced technology in many fields, such as machinery, electricity, liquid, light, control, engineering, etc. Its manufacturing process is complex, and its degree of autonomy directly reflects the industrial level and industrial chain perfection of a country.

Size, there are "super" and "tiny". A shield machine with a diameter of only 0.5 meters, "the sparrow is small and complete."

Technology, from running to part leading. Horizontal excavation, vertical shaft, inclined shaft, various modes and special-shaped sections are not a problem.

Market share from supporting role to leading role. The output of rock tunnel boring machine of China Railway Construction Heavy Industry has been the first in China for five consecutive years. The domestic brand shield machine represented by China Railway Construction Heavy Industry has climbed to more than 95% in the domestic market share, accounting for two-thirds of the global market share.

People have no me, people have my advantages, and China roadheader strode out of the country.

In 1950s, Soviet experts came to China to help Beijing plan the first subway line. Sixty years later, five shield machines from China Railway Construction Heavy Industry participated in the construction of the southwest section of the third interchange ring road of Moscow Metro, and were affectionately called "five golden flowers" by the locals.

The "Five Golden Flowers" proudly bloomed in snow, which overcame the extremely cold environment of minus 30 degrees Celsius, set a new record for local subway construction and became a model for overseas construction of shield machines in China.

On the eve of the Spring Festival in 2022, after more than seven hours of overseas connection, Railway Construction Heavy Industry finalized cooperation with an Italian construction company. China shield machine is about to enter the Italian market for the first time.

"Hundreds of technical parameters are compared one by one, and the attitude of the other party gradually changes from distrust to trust." Zhong Qing, an engineer from the Research and Design Institute of Railway Construction Heavy Industry Roadheader, said that China shield machine has comprehensive advantages in terms of price, performance, quality and service, and is more competitive than foreign brands. He said with emotion, "I used to be a teacher, but now I am a teacher." In less than 20 years, the change is too great. "

The reporter walked into the assembly workshop of Railway Construction Heavy Industry, but saw a shield machine being hoisted and tested in an orderly manner. The base label showed that the destination was Sri Lanka, India and Singapore. In the first quarter of this year, the amount of new overseas contracts signed by Railway Construction Heavy Industry increased by 9 times year-on-year.

Along the "Belt and Road", China equipment accelerates the equipment world. In 2021, Tiejian Heavy Industry ranked among the top 30 global construction machinery manufacturers and ranked first among the top 5 global full-face tunnel boring machine manufacturers.

Move the classroom into the workshop

I have a "billion-point" heart.

Deng Kangwei (a junior majoring in urban underground space engineering in Central South University)

It is accidental to choose the major of urban underground space engineering. On the weekend of my freshman year, I read several books related to urban underground space in the library and learned that the use of above-ground space is becoming increasingly saturated, and underground space will become the "main battlefield" for urban construction. So, when I subdivided my major, I chose this major.

This semester’s professional courses often talk about shield machines. As a young observer of Hunan Daily, I came to Tiejian Heavy Industry to observe the shield machine at close range. For me, it is like moving the classroom into the workshop and learning the principle and structure of the shield machine in front of books and drawings in class. It is a completely different experience.

It took me six hours to assemble the toy of shield machine building blocks presented by the enterprise, so I can experience the fun of "manufacturing" a shield machine. In fact, there are more than 30,000 large and small parts on a shield machine. From conventional diameter to the development of super-large diameter shield machine, technicians have devoted themselves to tackling more than 2900 days and nights.

I was deeply impressed by this statement that the shield machine has changed from a "printing machine" for foreigners to a "competitive machine" for China people. Scientific researchers have gnawed at the "hard bones" of core technologies, and industrial workers have developed the hard skills of striving for perfection, so that China’s independent research and development of shield machines is no longer subject to people, from zero foundation to mastering key core technologies, leading the world.

Walking into the super factory of shield machine, I saw the big scene of shield construction and became a "shield driver" as I wished. This "immersive experience class" made me feel the innovative power of hard-core technology, which made me feel "a little bit" and made a different plan for the future.

Urban underground space contains unlimited development space, and the future awaits us to change and create with broader knowledge and broader horizons.

　　[Global Network Report] According to Russian media reports such as RIA Novosti and Tass, the car of zahar Prilepin, a Russian writer and co-chairman of the "Just Russia-Patriots-For Truth" party, exploded in Nizhny Novgorod on the 6th, killing the driver and injuring Prilepin. Oleg Osipov, vice-chairman of the Russian Federal Security Council and assistant to Medvedev, chairman of the United Russia Party, said on the same day that Medvedev said in a telegram sent to Prilepin that the explosion in his car was a "despicable attack by Nazi extremists".

　　According to previous media reports, on the 6th local time, in Nizhny Novgorod, Russia, the car of zahar Prilepin, co-chairman of the Russian "Just Russia-Patriots-For Truth" party, exploded, killing the driver and injuring Prilepin himself. The Russian Ministry of Internal Affairs said on the same day that the suspect suspected of making this car bombing has been arrested. He is a man born in Ukraine, and the relevant Russian departments have characterized the case as a "terrorist attack". The investigation commission of the Russian Federation said that the suspect had admitted that he was instructed by the Ukrainian intelligence service. According to Ukrainian media reports, the Ukrainian National Security Agency said on the same day that it could not confirm or deny its participation in the car bombing.

　　The engine of a Boeing 787 Dreamliner of norwegian air shuttle Company broke down shortly after taking off on the 11th, and hot metal fragments flew out of the engine, which caused an "iron rain" in the Italian capital Rome.

　　The Times reported on the 12th that 25 cars and 12 houses were damaged to varying degrees in fiumicino, a suburb of Rome. Fortunately, no one was injured. Italian media reported that a man sunbathing in the garden was almost hit by debris. A small piece of debris burned the T-shirt he was wearing.

　　At about 4 pm on the 11th, the plane flew over the incident area at a height of about 400 meters, and the engine fragments about 5 to 10 centimeters long and sharp and hot fell, damaging the roof and car glass, setting the lawn on fire and leaving a small pit on the road.

　　Paula Dilazzaro, a resident, told the Italian newspaper Courier that the incident was "like the next big hail", but the sun was still there. "I went to the balcony, saw a steel storm, and then ran back to the house screaming". After the "iron rain" stopped, she found that a piece of hot metal smashed the rear windshield of her daughter’s car and set fire to a jacket on the back of the car.

　　The passenger plane, carrying 298 passengers, originally flew to Los Angeles, USA. After the incident, it spilled oil over the Adriatic Sea and made an emergency landing at fiumicino Airport.

　　Norwegian air shuttle said that the passenger plane "encountered technical problems a few minutes after take-off … … Then return to the airport and land safely. " The airline operator said that in view of the fact that the investigation is still going on, it cannot respond to media questions.

　　This passenger plane uses the "Trent 1000" engine made by British Rolls-Royce Company. This kind of engine has had many problems since it came out, and its high-pressure turbine blades are easy to crack, which once led to the grounding of passenger planes.

　　A Rolls-Royce spokesman said: "The aging rate of blades is faster than expected. We have found cracks that have occurred prematurely, but we have a solution." She said that the running Trent 1000 engine had never "airborne" metal fragments before.

　　Gregory Arlegui, an Italian aviation expert, said that the separation of metal fragments is a rare "non-inclusive fault". Although the safety of Boeing has been widely questioned due to two fatal air crashes, Arlegui believes that the focus of people’s attention on this incident will be the "engine manufacturer".

　　The shadow of the Peugeot 207CC left in Europe in the summer has not yet dissipated, and the new generation of Dongfeng Peugeot 207 has rushed to our eyes in the face of the cold winter wind. The unique temperament of the Peugeot 207CC division makes us think, and the European classic Lion King is running towards us quickly.

　　Although it is from Dongfeng Peugeot’s handwriting, its design has already reached international standards, with a steady atmosphere and personality. You will find the aesthetic balance of fashion, innovation and small cars in it. Generally speaking, it is not easy to design a sedan with a length of about 4m evenly and smoothly. There is an essential difference between the shape drawing and the real thing, mainly the placement of the internal components of the sedan. The short size of the sedan makes the rear axle and many parts of the suspension system often cause design problems for the trunk, so we often see the sedan with its tail tilted high. Dongfeng Peugeot 207 has put a lot of effort into the design of the rear, first of all, it makes the rear of the body look plump and thick, avoiding the height and frivolity of the trunk. The wide rear windshield matches the smooth lines of the trunk just right, and the large-size chrome lion logo on the curved luggage compartment lid makes the Dongfeng Peugeot 207 look quite large from the back.

　　The design of the front of the Dongfeng Peugeot 207 is self-evident. The wide smiley face design makes the lion eye headlights more sparkling, and the small round fog lamp also exudes charm. The U-shaped chrome lion logo is set against the honeycomb background, telling the pride of the lion. The wide front face is full of three-dimensional sense, the air intake with metal grille under the bumper echoes the black air intake on the engine cover, and the bumper extends in the direction of the wheel, which is cleverly combined with the fender. The original front face marks the birth of the latest generation of Peugeot sedans, making people unforgettable. Of course, the Dongfeng Peugeot 207 emphasizes the harmony of the whole vehicle and the coordination between the front and rear. The smooth streamline on the side has fully interpreted this point. A smooth curve wraps the small size and large space of the Dongfeng Peugeot 207 from front to back, making it particularly attractive.

　　The distance from Guilin to Longsheng is about 150km. Among the 50km of expressway, there is a section of expressway that is known as the most beautiful expressway in China. It winds between the beautiful mountains and rivers, like a silver streamer thrown in a picture scroll. We were fortunate to drive on this charming road with Dongfeng Peugeot 207. Since it has just been opened to traffic, there are very few vehicles. Except for the scenery, I can hardly see anything that interferes with my line of sight. With such a good opportunity, I decided to soar the speed of the car. The 1.6L engine brought not only the speed at the start, but also the acceleration in the middle and high sections was very good. It was easy to increase from 80km/h to 140km/h, as if it didn’t take much effort. The road ahead was still wide and smooth. I stepped on the accelerator to the bottom, the engine issued a uniform long sound, and the speed increased little by little again. The design of the Dongfeng Peugeot 207 sedan should enhance the balance of the vehicle at high speed. The control below the speed of 140km/h is very easy, and the direction is very sharp. As the vehicle speed rises further, the body begins to float, and it needs to concentrate on correcting the direction to deal with the impact of the road on the tires. Finally, I glanced at the speedometer and it has exceeded 170km/h, which is close to the maximum speed value given by the Dongfeng Peugeot 207.

　　Due to the fast speed of the car, the heavenly highway is gone in an instant, and we have crossed the edge of the mountains. I don’t understand why the ancestors of the Zhuang people settled in the depths of the mountains. We had to leave too many echoes of Dongfeng Peugeot 207 in the mountains. But the process of entering the mountain was beyond my expectations. The quiet lion did not even alarm the mountain gods, and moved quietly and quickly all the way. The twists and turns of the mountain road made me keep the gear below 3rd gear, and the undulating road conditions often pulled the speed very high. The excellent noise reduction effect of Dongfeng Peugeot 207 is the best way to repay this terraced picture. I can clearly feel that the noise of the engine is reduced, which is the function of the new sound insulation board, as well as the sound insulation measures around the engine and under the carpet. The improvement of the vehicle’s compactness is also the key to further weakening the noise. This is because many parts of the steel plate are lined, reducing the resonance, and the change of silence can be felt both inside and outside the vehicle.

　　In addition to the gentleman’s demeanor, the most exciting display of the Dongfeng Peugeot 207 is the style of the mountain road. The road leading to the Longji terraces is curved and narrow, and there are often trucks driving slowly under the pressure of speed, so you need to have enough acceleration and balance ability under emergency strain. Since the Dongfeng Peugeot 207 manual transmission is driven, the speed increase of the mountain road is relatively easy, and the vehicle is always in a strong torque output state. The low-speed torque output of this 1.6L engine has been enhanced to a certain extent. If you control it at about 4000r/min, there is no need to worry about the speed increase. Overtaking is only a matter of an instant. Smooth alignment on narrow mountain roads is the key to controlling the balance of the vehicle. The Dongfeng Peugeot 207, like its predecessors, reflects an innate adaptability to mountain roads. The car body is compact, the chassis is tough, and the direction of the lane change process during acceleration is very clear. The probability of a tire ringing when passing through a sharp bend quickly is also very low. The two sturdy swing arms of the Dongfeng Peugeot 207 rear axle should play a role. One swing arm enhances the toughness of the rear axle, and the other is a lateral stabilizer, so that the body can still run smoothly in a tilted state.

　　The interior space of the Dongfeng Peugeot 207 has been completely optimized. First of all, the material and assembly process have been greatly improved. The structure is tight, and the dark interior and three-dimensional dark fabric are dynamic. The manual transmission version uses a single-color dark interior with a sporty style, while the higher automatic transmission version uses a warm and elegant two-color interior. The design style of the instrument panel is very dynamic. The three unique chrome-framed round meters are on a black or white background according to different model versions. No matter which base color, it is full of sports. The trend of the air conditioner and the upper part of the instrument panel also use a fashionable silver-gray chrome-plated decorative strip, which also interprets youth and vitality as much as possible.

　　However, the biggest surprise of the Dongfeng Peugeot 207 came from the trunk, the rear seats can be manually removed, the shock absorbers and wheels have no impact on the luggage compartment, making it a regular rectangle, and the oversized volume of nearly 400L is enough to meet the needs of the family. The luggage compartment also does not affect the space in the rear and the rear view. The rear of the front seat backrest is slightly embedded, thus creating a more spacious legroom for the rear passengers.

　　Let’s take a look at this smiling sedan again. The market for such products is not only further enriched, but this time there is a well-proportioned athlete. With the appearance of the luggage compartment, the target customer base of Dongfeng Peugeot 207 will also be further expanded, attracting mature consumers. Of course, there is also the appropriate price.
