speed up apply the brakes oil consumption second rice rise A New Generation of Good Samaritan Tested 2013 Jetta 1.6L Automatic Transmission Evaluation Editor-Liang Wei:

We have tested the new Santana before. Now I don’t know what to say about the new Jetta. Everyone is already familiar with every detail. I don’t know why, the performance test results of the new Jetta are much slower than that of the new Santana. Perhaps it is the differentiation treatment specially made by Volkswagen Group for the two products. We can only understand it this way. In addition, as an entry-level model, the new Jetta is still a little expensive, and some discounts will be more cost-effective, so we can wait.

Evaluation Editor-Hu Zhengyu:

Finally put the new Jetta to the test. The public has created such a large number of regular troops with uniformity and no personality to fight, and they are good at doing business.

Evaluation Editor-Luo Hao:

There is nothing to say to the same family of family cars. It won’t let you down, but it will never give you any surprises, that’s all.

Huawei’s self-developed operating system has finally been unveiled.

On August 9th, Huawei Consumer Business officially released its brand-new distributed operating system "HarmonyOS OS" based on microkernel and facing all scenarios to the whole world at its global developer conference.

Huawei said that HarmonyOS OS is the product of welcoming the era of full-scene experience, and will give full play to its advantages of lightweight, compact and powerful functions, and take the lead in applying it to smart terminals such as smart watches, smart screens, vehicle-mounted equipment and smart speakers, and strive to build a cross-terminal integration and sharing ecosystem, reshape a safe and reliable operating environment, and create a new experience of full-scene smart life for consumers. In other words, Huawei’s smart terminal will use its own operating system in the future.

"As early as ten years ago, Huawei began to think about facing the future era of full-scenario wisdom. Users need a new experience that is cross-hardware, cross-platform and seamless, which completely breaks through the physical space." Yu Chengdong, CEO of Huawei’s consumer business, said when introducing the original intention of HarmonyOS’s OS development: "With the advent of the era of full-scenario wisdom, Huawei believes that it is necessary to further improve the cross-platform capability of the operating system, including the ability to support full-scenario, cross-device and platform, and the ability to cope with low latency and high security challenges. Therefore, the embryonic form of HarmonyOS OS has gradually formed. It can be said that the starting point of HarmonyOS OS is different from Android and iOS. It is a brand-new distributed operating system based on microkernel and facing the whole scene, which can meet the requirements of smooth experience of the whole scene, trusted security at the architecture level, seamless collaboration across terminals and multi-terminal deployment at one time. HarmonyOS should be born in the future. "

According to Huawei, HarmonyOS OS is designed to meet the high-standard connection requirements of intelligent experience in the whole scene, and it has four system solutions.

First of all, the distributed architecture is used for terminal OS for the first time, which can realize seamless collaborative experience across terminals. HarmonyOS OS’s "Distributed OS Architecture" and "Distributed Soft Bus Technology" shield the application developers from the realization difficulty of the underlying technology of the corresponding distributed application through the four capabilities of public communication platform, distributed data management, distributed capability scheduling and virtual peripherals, so that developers can focus on their own business logic and develop cross-terminal distributed applications like developing the same terminal, and also enable the end consumers to enjoy the seamless experience brought by the powerful cross-terminal business collaboration capability for various usage scenarios.

Secondly, it is determined that the delay engine and high-performance IPC technology can realize the natural fluency of the system. HarmonyOS OS solves the problem of insufficient performance of the existing system by using two technologies: deterministic delay engine and high-performance IPC. The delay engine can allocate the priority and time limit of task execution in the system for scheduling before task execution, and the task resources with high priority will give priority to scheduling, and the application response delay will be reduced by 25.7%. The compact structure of HarmonyOS microkernel greatly improves the performance of IPC (Inter-process Communication), and the efficiency of inter-process communication is 5 times higher than that of the existing system.

Thirdly, remould the trustworthiness and security of terminal equipment based on microkernel architecture. HarmonyOS OS adopts a brand-new microkernel design, which has stronger security features and low latency. The basic idea of microkernel design is to simplify the kernel function, realize system services as much as possible in the user mode outside the kernel, and add mutual security protection. Microkernel only provides the most basic services, such as multi-process scheduling and multi-process communication.

HarmonyOS OS applies microkernel technology to trusted execution environment (TEE), and reconstructs trusted security through formal methods. Formal method is an effective means to verify the correctness and no loopholes of the system from the source by mathematical methods. Traditional verification methods, such as functional verification and simulated attack, can only be verified in selected limited scenarios, while formal methods can verify all software running paths through data models. HarmonyOS OS applies formal method to terminal TEE for the first time, which significantly improves the security level. At the same time, because the code amount of HarmonyOS OS microkernel is only one thousandth of that of Linux macro kernel, its attack probability is also greatly reduced.

Finally, the unified IDE supports one-time development and multi-terminal deployment to realize cross-terminal ecological sharing. HarmonyOS OS relies on multi-terminal development IDE, multi-language unified compilation, distributed architecture Kit to provide screen layout controls and automatic adaptation of interaction, support control drag and drop, and preview-oriented visual programming, so that developers can efficiently build multi-terminal automatic running App based on the same project, realize real one-time development and multi-terminal deployment, and realize sharing ecology among devices. Huawei Ark Compiler is the first static compiler to replace Android virtual machine mode, which allows developers to compile high-level languages into machine code at one time in the development environment. In addition, Ark compiler will support multilingual unified compilation in the future, which can greatly improve the development efficiency.

Huawei also announced the evolution roadmap of HarmonyOS kernel and OS, and will take the lead in using HarmonyOS OS 1.0 in the smart screen products launched this year. In the next three years, in addition to improving related technologies, HarmonyOS OS will be gradually applied to more intelligent devices such as wearable devices, smart screens and car machines.

At the same time, in order to rapidly promote the ecological development of OS in HarmonyOS, HarmonyOS OS will open its source to developers all over the world, and promote the establishment of an open source foundation and an open source community, so as to jointly promote the development of HarmonyOS with developers and make suggestions on industrial or technological development through discussion.

Yu Chengdong believes that China already has a sound application ecology and a huge user base. In the future, Huawei will rely on China to build the HarmonyOS OS ecosystem globally. By focusing on new values, it will open up its core capabilities in communication, photography, full scene and AI, and work with ecological partners from all walks of life to create applications and services with better consumer experience, inject new vitality into the industry, and create a new experience and ecology with full scene intelligence. "We believe that the launch of HarmonyOS OS will greatly enhance the vitality and ecology of the industry. We welcome global developers to actively support HarmonyOS’s OS ecological construction and jointly create a full-scenario intelligent life experience for consumers. ".

[business card]

"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.

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.

Automobile Quan Huafu News At the end of 2023, there was an important model quietly listed in a controversy, which was Chery’s high-end new energy model-Xingtu Xingjiyuan ES. But before the Spring Festival in 2024, Xingtu New Energy added a new car: Xingjiyuan ET. In this way, the star-to-star era sequence has formed the lineup of Gemini models of cars ES and SUV ET.

Today, the model we test drive is the pure electric four-wheel drive version of Star Era ET, with the maximum power of 353kW and the maximum horsepower of 480 horsepower. The curb weight has reached 2339kg, the body size is 4955/1975/1698mm, and the wheelbase is 3 meters. Star Era ET battery pack is Contemporary Amperex Technology Co., Limited, and the wheel hub size reaches 255/50 R20. The size, space and power of the whole vehicle are enough to see and use.

Wild and hard enough to go out and play without any worries.

Accidents always come unexpectedly. At the beginning of the test drive meeting, it was actually a direct hard-core cross-country, opening the shoal and wading! It’s the first time to drive a new energy SUV across the river. I directly turned on the off-road mode of Star Era ET and slowly tried to drive the car into the river.

The feeling and sound of a behemoth with a weight of 2.3 tons pressing on the pebbles at the bottom of the river make driving gradually enter the state. According to the test drive coach, the wading depth of Star Age ET is 750mm, which is more than that of Bobcats.

After wading, there are conventional hard-core cross-country venues, bullet pits and cross-axle pavements. However, there is no pressure on medium and large SUVs such as Xingjiyuan ET. In the whole process, the torque at the wheel end of Xingjiyuan ET is distributed in place, and the wheels are locked as soon as they slip, and the support of the suspension is very tight. It can be seen that Chery Automobile’s "cloud structure" plays a decisive role in the adjustment and promotion of the whole vehicle.

Big enough and comfortable enough, and it is easy and comfortable to travel at home.

Having said that, the positioning of Star Era ET is, after all, an urban mobility SUV. After off-road measurement, the off-road capability of Star Era ET has made people worry about nothing, but what about the comfort and space of positioning home cities for mobility?

The wheelbase is 3 meters and the body size is close to 5 meters. Such parameters can be imagined in the interior space. Whether in the front row or the back row, the head space and leg space are more than enough, and the flat floor in the back row is also frequently praised by the teachers who participated in the test drive.

In the front cab, Star Age ET is equipped with the main zero-gravity passenger seat of the model. The support of the seat to the body is in place, which makes the human body feel comfortable. In fact, the armrest box is also a highlight, which can be moved back and forth for a certain distance.

Auto Quan Huafu Review: At present, Star Era ET only has 5 seats. For new energy vehicles of this size, 6 seats and 7 seats can actually be added later. Moreover, the official logo, in the second quarter of this year, Star Era ET will usher in an extended-range model, so that people with pure battery life anxiety have more choices.

Recently, the Interpretation of the Supreme People’s Court on Several Issues Concerning the Application of Laws in the Trial of Punitive Compensation Disputes over Food and Drugs (hereinafter referred to as the Interpretation) was released on August 21, and came into effect on August 22. This document regulates malicious high claims, continuous purchase claims and repeated claims, and all support punitive compensation claims within the scope of reasonable living and consumption needs. This is a wake-up call for the professional counterfeiters: do not let "counterfeiting" become "fake fighting".

For a long time, professional counterfeiters have played a complex and subtle role in the field of consumer rights protection. On the one hand, with their keen insight and mastery of laws and regulations, they exposed and cracked down on batches of fake and shoddy products, effectively purified the market environment and protected the legitimate rights and interests of consumers; On the other hand, driven by interests, some professional counterfeiters have gradually deviated from the track of justice, alienated "counterfeiting" into a tool for profit, and even resorted to illegal means to extort money, seriously disrupting the market order and damaging the authority and credibility of the law.

The promulgation of the new Interpretation is a powerful response to this chaos. It clearly defines the boundary of "knowing and buying fakes" in the field of food and medicine, and emphasizes that punitive damages must be within the scope of reasonable living and consumption needs, which is not only a further guarantee for consumers’ legitimate rights and interests, but also a profound norm for professional counterfeiting. It tells us that the law supports legitimate and legitimate rights protection behavior, rather than making illegal profits by taking advantage of legal loopholes.

The existence of professional counterfeiters should have been a positive force in the market supervision system and a line of defense between consumers and businesses. However, when "counterfeiting" becomes "counterfeiting", this force loses its due glory and even becomes a negative factor in the market. Malicious counterfeiters use legal loopholes to extort money in the name of "counterfeiting", which not only makes businesses miserable, but also makes the regulatory authorities exhausted, resulting in a great waste of social resources. In the long run, it will not only weaken the public’s trust in the law, but also cause more social contradictions and problems.

Therefore, we must be soberly aware that professional counterfeiting is not illegal, and their behavior also needs to be strictly bound and supervised by law. For those malicious counterfeiters who extort money in the name of counterfeiting, the law must show their swords, hell to pay. At the same time, we should also strengthen the education and guidance to consumers, improve their legal awareness and self-protection ability, so that they can rationally and legally safeguard their rights and interests.

In addition, the government and all sectors of society should work together to build a more perfect market supervision system. By strengthening the construction of laws and regulations, improving the efficiency of law enforcement, increasing punishment and other measures, a powerful deterrent to counterfeit and shoddy products has been formed. At the same time, encourage and support all sectors of society to participate in market supervision, and form a good atmosphere for the whole society to govern together. Only in this way can "counterfeiting" return to its true meaning and make the market environment clearer and healthier.

Judging from the recent automobile sales data, the sales volume of domestic brands is obviously higher than that of joint-venture brands, but in joint-venture brands, the sales volume of Japanese brands has dropped significantly, which also proves from another aspect that domestic brands are rising rapidly, especially in the field of new energy. Of course, many domestic brands still focus on fuel vehicles, such as the main sales models under the brand. When it comes to Changan brand, I really want to talk about the original budget of 110,000, giving up and finally choosing.

In fact, Changan Yidong’s car is very cost-effective, so we can’t be too picky about it, but after driving for 3 years, the owner expressed regret. Why? First of all, compared with Honda Civic, Changan Yidong is not a direct competitor, but I also believe that many people have seen Honda Civic, but now they have Changan Yidong, mainly because of insufficient budget.

Three years ago, the budget was more than 100,000 yuan to buy a car. At the beginning, Honda Civic, Hyundai Fista and other models were all under consideration. From the perspective of joint venture brands, the landing price of models with a displacement of more than 1.4T was basically around 140,000-150,000 yuan, but at that time, it was only more than 70,000 yuan. In fact, it is also possible to choose to buy some of the above models in stages, but after thinking about it, Chang’ an is much cheaper, especially 1.4T blue.

At that time, I took a fancy to the top model of Changan Yidong, and the final landing was more than 110,000 by stages. If I choose Honda Civic, it should cost more than 40,000 yuan. If I go back and choose again now, I would rather borrow more than 40,000 yuan. Now Chang ‘an Yidong has been in operation for three years. Apart from the commendable power performance, the interior and various configurations are not bad. Let’s formally talk about why we regret choosing Chang ‘an Yidong.

Changan Yidong 1.4T Blue Whale engine is still very powerful, especially with a 7-speed dual-clutch gearbox. However, judging from the performance of fuel consumption for three years, basically, the fuel consumption for commuting in urban areas can reach the standard of about 9L, and the high-speed fuel consumption is better, about 6L, which is still a certain gap compared with the 1.5T Earth Dream engine. As for the gearbox, the 1.4T power version of Changan Yidong has leaked oil. Every time I open the hood, I can see the oil on it. I wonder if it will affect the service life of the gearbox in the future.

After driving Chang ‘an Yidong for more than three years, I traveled more than 20,000 kilometers. In the first two years, there was no abnormality in the vehicle. In the third year, when the warranty period was approaching, within three months, the co-pilot touch panel failed, the steering gear of the steering wheel was abnormal, and the engine bracket was aging. However, the problem with the steering gear was the common problem of Chang ‘an Yidong, which was fortunately within the three-year warranty period, otherwise everything would have to be paid by myself, so I only traveled more than 20,000 kilometers.

If there is any problem during the warranty period, it will be repaired free of charge, so there is not much regret. However, in terms of face, it is the reason why I regret buying it most. At this time, some people will say that the car can travel instead of walking, but the reality is that many girls will not get on your car and play with others to take other better cars, which is why BBA is so popular in China. Changan brand is in the eyes of many people. It is the low price, so I subconsciously think that your income is not high, which will greatly discount your personal image. If you choose Honda Civic, I believe others will have a higher eye for people.
