In the domestic automobile market, with the continuous progress of technology and the diversification of consumer demand, as one of the core components of the automobile, the performance and reliability of the gearbox are directly related to the driving experience and the overall quality of the vehicle. However, although domestic gearboxes have made remarkable progress in recent years, there are still some products that have attracted much attention because of their high failure rate. This paper will analyze and rank the three domestic gearboxes with high failure rate in detail: universal 6-speed automatic transmission 6T30(MH9), Peugeot Citroen 4-speed automatic transmission AT8 and BYD 6-speed wet powershift 6DT35.

1. Basic overview

As an important gearbox product of GM, the general 6-speed automatic transmission 6T30(MH9) is widely used in old Cruze, Yinglang and other models. This gearbox was once favored by the market for its multi-gear design and relatively smooth shifting experience. However, with the passage of time, the problem of high failure rate is gradually exposed.

2. The main fault performance

• Computer board failureThe control module (computer board) of 6T30 gearbox is one of its core components, which is responsible for receiving and processing signals from sensors and actuators to control the shift logic of gearbox. However, according to the owner’s report, the computer board is prone to failure during use, which leads to abnormal operation of the gearbox, such as sudden shift, inability to upshift or downshift.
• The sense of frustration is obviousIn addition to the computer board failure, the frustration of 6T30 gearbox during gear shifting is also a common problem reflected by car owners. This sense of frustration not only affects the driving comfort, but also may cause additional wear and tear to the mechanical parts inside the gearbox.
• Abnormal sound problemSome car owners also report that they will hear abnormal noise from the gearbox during driving, which is usually related to the wear of gears or bearings inside the gearbox. Abnormal noise not only affects the driving experience, but also may be a precursor to gearbox failure.

3. Solutions and improvements

In view of the above problems, GM has upgraded and improved the 6T30 gearbox several times. For example, optimize the control algorithm of computer board to improve its stability and reliability; Improve the lubrication system and seals inside the gearbox to reduce wear and abnormal noise; And strengthen the quality control and testing in the production process. However, due to the large number of old models and the high upgrade cost, some vehicles may still use the original gearbox.

1. Basic overview

Peugeot Citroen 4-speed automatic transmission AT8 is an old gearbox product, which is mainly used in old models such as 308, 408, C5 and Sega. This gearbox adopts fuzzy control theory to realize the automatic shift function under different slopes and load, but it has exposed a high failure rate in actual use.

2. The main fault performance

• Unable to shift gearsThe problem that AT8 gearbox can’t shift gears is one of the biggest headaches for car owners. According to reports, this fault usually occurs when the vehicle suddenly fails to shift gears during driving, resulting in the vehicle not being able to run normally.
• Fault lightWhen the gearbox fails, the fault light on the instrument panel will light up to remind the driver. However, for AT8 gearbox, the lighting of the fault light often means that a serious fault has occurred.
• Shift logic confusionIn addition to being unable to shift gears, the shifting logic of AT8 gearbox is often criticized by car owners. Some car owners report that the shifting timing and logic of the gearbox are not accurate and reasonable enough during driving, which greatly reduces the driving experience.

3. Solutions and alternatives

Because the failure rate of AT8 gearbox is high and difficult to repair, many car owners choose to replace the gearbox or upgrade the model to solve the problem. At the same time, with the continuous progress of automobile technology and the upgrading of consumer demand, more and more models are equipped with more advanced and reliable gearbox products.

1. Basic overview

BYD 6-speed wet powershift 6DT35 is a gearbox product independently developed by BYD Auto, which is mainly used in BYD Tang New Energy and other vehicles. This gearbox adopts a wet dual clutch structure to improve the smoothness and durability of shifting. However, its failure rate is relatively high in actual use.

2. The main fault performance

• Abnormal sound and frustrationAccording to the owner’s report, the 6DT35 gearbox often has abnormal sound and frustration during starting and accelerating. This kind of fault not only affects the driving comfort, but also may cause damage to the mechanical parts inside the gearbox.
• Oil leakage problemOil leakage is another common problem of 6DT35 gearbox. The oil leakage caused by the quality problem or improper installation of the internal seal of the gearbox not only wastes resources, but also may affect the performance and safety of the vehicle.
• Shift logic problemSome car owners also report that the shifting logic of 6DT35 gearbox is not accurate and reasonable enough, which leads to untimely shifting or excessive shifting impact during driving.

3. Solutions and suggestions for improvement

In view of the above problems, BYD has taken a series of measures to improve and upgrade. For example, optimize the internal structure design of gearbox to improve its durability and reliability; Strengthen the quality control and testing in the production process to ensure the stability of product quality; And strengthen the construction of after-sales service system to improve customer satisfaction. However, due to the limitation of technical level and production cost, some problems may still be difficult to be completely solved.

To sum up, the universal 6-speed automatic transmission 6T30(MH9), Peugeot Citroen 4-speed automatic transmission AT8 and BYD 6-speed wet powershift 6DT35 are three products with high failure rate in domestic gearboxes. There are many problems in performance, durability and reliability of these gearboxes, which have brought many troubles to consumers. However, with the continuous progress of automobile technology and the intensification of market competition, it is believed that the overall quality of domestic gearboxes will be continuously improved in the future to provide consumers with a better and more reliable driving experience. At the same time, consumers should pay enough attention to the performance and quality of gearbox when buying cars to avoid unnecessary troubles and losses caused by gearbox failure.

　　Xinhua News Agency, Beijing, December 7 (a global hotspot) Putin’s real challenge in his fourth presidential campaign is after winning the election.

　　Xinhua news agency reporter

　　"I will run for the Russian presidential election."

　　On the 6th, Russian President Vladimir Putin said this when answering a question from a worker of Nizhny Novgorod Gorky Automobile Factory.

　　This is the fourth time Putin has participated in the Russian presidential election. At present, it seems that Putin lacks a strong campaign opponent and it is not difficult to be re-elected. However, analysts believe that Russia currently has a series of thorny problems in diplomacy and economy, which will test the winner of the election.

　　News fact

　　When Putin met with the workers of Gorky Automobile Factory on the same day, he said: "There is no better place than this place and this moment to announce (stand for election) … … Russia will keep moving forward, and no one can stop this progress at any time. "

　　Russia is scheduled to hold a new presidential election in March 2018. In recent months, Putin has been asked on many occasions whether to stand for election, but he has previously said that he has not decided yet.

　　According to a poll released by Russian polling agency Levada Center on the 4th, 53% of the respondents will vote for Putin in the upcoming weekend, and the second and third competitors will get 4% and 3% respectively.

　　According to a poll released by the Russian polling agency "Public Opinion" Foundation in November, 81% of the Russian people think that Putin has done a good job in the presidency, and 80% of the people have expressed their trust in Putin.

　　Remizov, director of the Russian National Institute for Strategic Studies, said that both Putin’s supporters and opponents are well aware of the election results.

　　[Depth analysis]

　　Analysts believe that since Putin was elected president for the first time, Russia’s status as a big country has been consolidated. In recent years, the Russian Air Force has shown its talents in Syria. Russia has resolutely defended its national interests through a tough foreign policy. Putin’s prestige has never been higher, and he is regarded by the Russian people as a symbol of stability and the realization of a strong country. At the same time, Putin gradually built a younger, more dynamic and more professional ruling team, and the political foundation was more stable, which provided him with organizational guarantee for focusing on the future.

　　On the other hand, the opposition camp, with complex members, lack of "leaders" and practical ideas and programs, is difficult to pose a practical challenge to Putin.

　　Public opinion generally believes that Putin’s challenge is not to win the general election, but how to deal with various problems in power after the election: how to reverse Russia-US relations and reduce the negative impact on the economy and people’s lives caused by confrontation and Western sanctions? How to alleviate the polarization between the rich and the poor and curb corruption? How to adjust Russia’s economic development model to adapt to the breakthrough technological revolution in the fields of finance, commerce, information technology and medical care?

　　[First Comment]

　　Putin’s election is reasonable and expected, and even being re-elected is considered to be only a matter of time.

　　From a little-known former agent to an "iron-fisted president" in charge of a huge country, Putin’s political career is almost equivalent to the contemporary history of Russian countries. In a sense, Putin has shaped Russia today.

　　In the past few years, Russia has experienced the pain of the Ukrainian crisis and the ensuing economic downturn. After drawing a painful lesson, Russia under Putin abandoned its previous unrealistic illusions about the West and established a global policy of turning to the East, taking the Middle East as a stronghold and opening up a "circle of friends" by sending troops to Syria.

　　Although the economic structure, living standards and corruption have been criticized, and the voices of the West are constantly singing down Russia, Putin’s high support rate and Russia’s stable social situation show that the road taken by Putin to lead Russia represents the will of the Russian people. As a leader who pursues stability, if he wins the election, Putin will undoubtedly continue his current domestic and foreign policy.

　　[Background link]

　　Putin was born in Leningrad (now St. Petersburg) in October 1952, and graduated from the Law Department of Leningrad University in 1975 with an associate doctorate in economics. He worked in the national security agencies of the Soviet Union, including in the GDR from 1985 to 1990.

　　Putin served as acting president on December 31, 1999, was elected president of Russia on March 26, 2000 and was re-elected in 2004. Because the Russian Constitution stipulates that the same person cannot serve as president for more than two consecutive terms, Putin did not participate in the presidential election in 2008, but became the prime minister of the government.

　　At the end of 2008, the Russian State Duma (the lower house of parliament) passed a constitutional amendment, extending the term of office of the president from four years to six years, which will apply from the newly elected president in 2012. In March 2012, Putin was elected president for the third time. (Reporter: Wei Lianglei, Wang Chendi, Zhao Yan; Editor: Shang Jing, Sun Hao, Wang Fengfeng)

　　Together in the same boat, together for common development

　　A century of changes superimposed on a century of epidemics, the international security situation continues to be turbulent, the world economy is facing downside risks, unilateralism, protectionism and hegemony are still rampant, all parties expect this G20 summit to focus on the theme of "common recovery, strong recovery", to provide new policy guidance for solving major practical problems in global development and improving global economic governance.

　　The attendance of the Chairperson of the Supreme Leader at the G20 Bali Summit is the first time that a top Chinese leader has attended a multilateral summit since the 20th National Congress of the Communist Party of China was successfully held. In the past nine years, the Chairperson of the Supreme Leader has attended all G20 summits and put forward a global economic governance concept based on equality, openness-oriented, cooperation-driven, and sharing-oriented. He advocated that development issues be placed in a prominent position in the global macro policy framework. He advocated innovative development and the construction of an open world economy. He advocated that all countries strengthen macroeconomic policy communication and coordination, and put forward China’s plan for improving global economic governance.

　　"We should put people at the center, enhance the fairness, effectiveness and inclusiveness of global development, and strive not to leave any country behind." At the G20 Rome Summit in 2021, the President of the Supreme Leader called on all countries to practice true multilateralism, create a future through united actions, and demonstrate responsibility for the world.

　　At present, changes in the world, times, and history are unfolding in an unprecedented manner. Standing at the height of the development process of human history, the Supreme Leader and Chairperson put forward global development initiatives and global security initiatives in 2021 and 2022, injecting strong ideological impetus into cracking the growing peace deficit, development deficit, security deficit, and governance deficit, which have been widely recognized and actively responded to by the international community.

　　Former United Nations Secretary-General Ban Ki-moon said that the series of initiatives put forward by the Supreme Leader provide effective solutions for all countries to address development challenges and promote common development, and are based on multilateralism to reinvigorate international cooperation and solidarity and guide the international community towards a more inclusive, sustainable and resilient future.

　　"The G20 not only belongs to the 20 members, but also to the whole world. Our goal is to make growth and development benefit all countries and people, and to make the lives of people of all countries, especially those in developing countries, better day by day!" The words of the Supreme Leader at the opening ceremony of the G20 Business Summit in 2016 expressed the common aspiration of the vast number of people who love peace and pursue development.

　　During the visit, the supreme leader will hold bilateral meetings with French President Emmanuel Macron, US President Joe Biden, Senegalese President Sall, Argentine President Fernandez and other leaders. "China is committed to promoting harmonious coexistence among countries, promoting cooperation and development, and is a beacon of hope in the current world full of uncertainties," said Luis Delgaro, director of academic research at the Center for Advanced Studies in the Development of Emerging Economies in Venezuela.

　　Muhadi Sugiono, an international relations expert at Gachamada University in Indonesia, said that he expects China to continue to play its role as a responsible major country, and to promote all parties at the G20 summit to focus on common interests, discuss and formulate good policies that benefit developing countries and promote global economic recovery.

　　Openness and integration, setting the course for Asia-Pacific development

　　"The vine of the sweet potato extends in all directions, but its tubers always grow at the root. In the same way, no matter how far it develops, China will take root in the Asia-Pacific, build the Asia-Pacific, and benefit the Asia-Pacific." When attending the APEC Business Leaders’ Summit in Peru in November 2016, the Supreme Leader used the sweet potato as a metaphor to vividly illustrate the determination and sincerity of China and Asia-Pacific countries to move forward and build dreams together.

　　APEC is an important economic cooperation platform in the Asia-Pacific region. Since China joined the organization 31 years ago, it has always advocated open regionalism, been committed to promoting trade and investment liberalization and facilitation, and economic and technological cooperation, and played a positive role in building an open world economy, supporting the multilateral trading system, and leading economic globalization.

　　At the APEC Economic Leaders’ Informal Meeting, the Chairperson of the Supreme Leader repeatedly expounded on the concept and significance of building an open, inclusive, innovative growth, connectivity, and win-win Asia-Pacific community of shared future, emphasizing that Asia-Pacific economic cooperation has never been a zero-sum game, a political game where you lose and I win, but a development platform for mutual achievement and mutual benefit. "This is looking at issues from the perspective of the overall interests of mankind," said Xu Qingqi, director of the New Asia Strategic Research Center in Malaysia.

　　China and Indonesia are at similar stages of development, with shared interests, shared ideas and paths, and their future and destiny are at stake. In 2013 and 2015, the President of the Supreme Leader visited Indonesia twice, where he proposed to the world for the first time to jointly build the 21st Century Maritime Silk Road. In July this year, Indonesian President Joko Widodo paid his fifth visit to China, and the two heads of state jointly established the grand vision of building a China-Indonesia community with a shared future.

　　In recent years, the new pattern of bilateral relations between China and Indonesia has continued to deepen. In 2021, the bilateral trade volume broke through the US $100 billion mark in a historic manner. The joint construction of the "Belt and Road Initiative" is actively connected with the concept of "Global Maritime Fulcrum". Cooperation projects such as the "Regional Comprehensive Economic Corridor" and the "Two Countries’ Double Parks" are advancing steadily. The two sides signed a memorandum of understanding on strengthening maritime cooperation, incorporating maritime cooperation into the China-Indonesia high-level dialogue and cooperation mechanism. President Joko said: "The good cooperation between Indonesia and China reflects the strategic nature of bilateral relations, which is positive energy for the region and the world."

　　Since the establishment of diplomatic relations between China and Thailand 47 years ago, the relationship between the two countries has shown strong vitality over time. "China and Thailand are one family dear" has become a broad consensus between the two peoples. Since assuming the presidency, the Supreme Leader has received Thai Prime Minister Prayuth to China five times. In July 2020, the Supreme Leader and Prime Minister Prayuth had a phone call, injecting confidence and impetus into the two countries to work together to tackle the challenges of the epidemic and promote practical cooperation.

The following article is from New Consumer Daily, written by Tang Zhixiao.

New Consumer Daily.

The products of Cailian are devoted to reporting and studying the new trends, new products, new models and new investments in the fields of big consumption and going to sea in China, so as to provide consumers, investors and researchers with the best information on consumption and going to sea.

Yesterday, Huawei’s new 30-fold screen Mate XT extraordinary master opened the pre-sale online and offline simultaneously.

Official website showed that the reservation ended on September 19th, and it was officially put on sale on the 20th. Up to now, more than 1.9 million people have reserved this mobile phone in Huawei official website, and the number of reservations is still growing.

"science and technology innovation board Daily" reporter learned from offline stores that at present, the extraordinary masters of Huawei’s three-fold screen Mate XT have been sent to stores all over the country. Some salespeople told reporters: "The prototypes of some stores in Shenzhen have arrived, and the quantity of arrival varies according to different stores. Some stores even have only two or three orders. "

The above-mentioned Huawei sales person added to the science and technology innovation board Daily reporter that it is impossible to disclose the specific price of the product and unpack the prototype before the press conference, otherwise it will be fined more than 500,000 yuan.

"At present, we only register the intended reservation in our store, not make an informal reservation. After the product is officially listed, the store will inform consumers to pick up the goods at the store in the order of registration. " The Huawei salesperson said.

It is understood that when Mate60 and Pura70 series went on the market, Huawei’s official direct stores also made spot reservations by means of intention registration. Booking users still need to pick up the goods on the spot within the time limit for booking stores, and only one store can be selected for booking.

Unlike direct stores, some dealer stores have invited customers to make reservations.

A Huawei dealer store told the science and technology innovation board Journal reporter: "We only accept reservations from members of Huawei Mall above V3, and we need to pay a deposit of 5,000 yuan. Due to the scarcity of goods, Mate XT extraordinary masters need to bind HUAWEI Care+ to buy together."

The dealer admitted that there must be a higher premium for the previous three-fold screen, and the possibility of tying other related accessories besides Care+ was not ruled out.

Outside the online store, the science and technology innovation board Journal reporter found that some "scalpers" also put the order of Huawei Mate XT extraordinary masters on the second-hand trading platform, and the pricing is basically around 20,000 to 23,000 yuan.

During the consultation, the merchant told the science and technology innovation board Daily reporter bluntly: "After the sale in the morning, there were many inquiries about the specific price of the 30% discount screen, and we didn’t know. The price marked now is only the price of the basic model (16+512GB). According to the selected style configuration, the price will be increased later. "

As early as February this year, it was reported that Huawei was developing a "three-fold screen mobile phone", which will be available in the second quarter of this year at the earliest.

In August this year, Yu Chengdong was photographed using a three-folding screen mobile phone on the plane. On the left of the three screens, there was a message list, and on the right, there was a webpage content. When all the screens were unfolded, the inner screen was much larger than the ordinary large-folding mobile phone, and a stylus was suspected to be hidden in the protective case on the side. Yu Chengdong also revealed in Dong Yuhui’s live broadcast room that "the next generation of folding screens can be imagined by others, but they can’t be made. We have been thinking about it for five years, and finally it may be coming out soon. "

On September 3rd, Huawei Terminal officially announced Mate XT, a new member of the extraordinary master brand through Weibo. Yu Chengdong, managing director of Huawei, chairman of BG and chairman of BU, a smart car solution, forwarded the Weibo with Mate XT’s extraordinary master mobile phone.

Some practitioners in the mobile phone industry believe that as a new form of folding screen, the cost of three folding screens is higher than that of folding screens. On the one hand, the screen is folded in and out at the same time, and the flexible screen is subjected to compressive stress and tensile stress at the same time, which is a huge test for the stress capacity of the flexible screen; On the other hand, the two reverse folding stresses will lead to the slippage of multi-layer and module structure, which will affect the stability and display life of screen module.

Recently, Voice Holdings has appeared in PHANTOM ULTIMATE 2, an ultra-thin and three-fold concept machine. From the product form, this concept machine adopts a zigzag folding mode. After being fully unfolded, the overall size is about 10.1 inches, and all the screens are on the same side, instead of having a screen on both sides like the current mainstream folding screen mobile phone.

A developer engaged in HarmonyOS application adaptation told the reporter of science and technology innovation board Daily that in terms of adaptation difficulty, the three-fold screen mobile phone is not high. "In the fully unfolded form, the application proportion of the three-fold screen mobile phone is similar to that of the tablet computer.

On August 30th, the tank brand brought its gasoline version, tank 500 Hi4-T Darth Vader and tank 700 Hi4-T to Chengdu Auto Show. At the Chengdu Auto Show four years ago, the tank made its debut; Four years later, the tank brand has 500,000 users, successfully activated the off-road market in China, and increased the market share of autonomous off-road to 83.1% with a market share of over 50%.

The gasoline version of Tank 400, which was unveiled at this year’s Chengdu Auto Show, is equipped with a brand-new 2.0T Miller cycle engine and the first domestic self-developed 9AT longitudinal transmission, which ensures the climbing ability and stability during off-road. The climbing ratio is as high as 57.24, and the minimum speed is 2.7km/h and the maximum torque output is 11000N·m, showing the low-speed and high-torque power characteristics required for extreme off-road.

At this time, the launch of pure fuel vehicles is not against the trend when the market share of new energy is 50%, but with a global perspective, it creates momentum for off-road in China and brings a more universal engine-driven version to China and regions with imperfect charging facilities around the world. In the future, the gasoline version of Tank 400 will be sold simultaneously in domestic and Eurasian markets.

This is also the technical value moat of Great Wall Motor with full power layout. In terms of power forms, tank brands have full power forms such as ICE, HEV and PHEV, and have various engine layouts such as 2.0T, 2.4T and 3.0T, as well as new energy power systems of 2.0th4-t and 3.0T Hi4-T, which meet the needs of different users around the world.

It is reported that the tank has specially set up an engineer R&D team for off-road use scenarios, formulated global calibration standards and established an off-road scene database. Up to now, Great Wall Motor has an R&D team of over 17,000 people, and has built six international laboratories around the world, with 11 world-leading test verification capabilities, and the R&D system is spread across seven countries and ten places.

For example, in terms of calibration, tank brands verify professional off-road in a harsh global environment. Every tank product has to undergo more than 3,000 rigorous tests in the past two years from research and development to listing. In Europe and Asia, where the temperature is-35 C, tanks are required to hold both fuel and Hi4-T models. In the Middle East, where the temperature is 50°C, tanks have to climb 120km/h on 16% ramps.

Hi4-T Darth Vader also appeared together. It is a highly customized and officially modified personality representative in the tank 500 series. With a brand-new blackening kit and deep black as the language, it combines introverted and profound, low-key and extraordinary with the current aesthetic trend and sports style, making it more personalized and fashionable.

Gu Yukun, executive deputy general manager of the tank brand, said, "Behind the sales volume of 500,000 is the tank’s persistence and love for technology, the courage to break the monopoly of high-end off-road, large displacement and multi-gear overseas technology, and the confidence of the Great Wall category innovation." To this end, Tanks released a brand night co-creation plan, which will create a brand night activity with time, place, personnel, guests and activities completely created by users.

In just four years, the tank brand entered the market with a new category, which not only firmly occupied a place in the market segment of hard+high-end luxury off-road SUV, but also led a group of independent brands to attack and expand overseas markets, and achieved great success. This requires not only practical and rigorous technology research and development, but also the courage to innovate and explore.

Edit =LAOT

At this stage, when it comes to new energy vehicles, everyone will always subjectively put the models of their own brands at a high level and the products of joint venture brands or even luxury brands at a low level.

It can only be said that the rapid development of independent brands in the field of new energy in recent years is beyond doubt, and their level is indeed high now. However, in the joint venture camp, not all new energy products created by brands are backward. For example, the EV5 launched by Kia, a Korean car company, is a model with relatively good comprehensive product strength.

We should judge the comprehensive strength of a product from the positioning of the car itself and its corresponding usage scenarios. It happened that Xiaobian had tested the Kia EV5 (picture | configuration | inquiry) in depth before. Today, I will share with you the actual performance of this car.

Kia EV5 is positioned as a pure electric compact SUV, combined with its unified front-drive single motor layout, it is not difficult to see that this car owner is playing a short-distance ride, and the main scene is daily home commuting. Such product positioning will obviously have a higher test for the practicality of Kia EV5.

First of all, the space, the length, width and height of KIA EV5 are 4615x1875x1715mm, and the wheelbase is 2750mm. As far as Xiaobian’s actual front and rear row riding experience is concerned, the space of this car is relatively good at this level, and the front and rear rows are relatively spacious, which is quite surprising.

In addition, KIA EV5 has many detailed designs based on practical attributes, such as the sitting design of the front driver and passenger, the small hook in the B-pillar area of the car, the front trunk with a certain capacity and the trunk with external discharge and anchor hook. All in all, KIA EV5 will make you feel the practical understanding of this car in detail, and also make the space as large as possible under the limited size of compact SUV.

Let’s talk about the performance at the configuration level. Kia EV5 is available in six different versions, which can be simply divided into the low, medium and high configuration version of the long battery life version and the low, medium and high configuration version of the standard battery life version. The configuration and price differences between the versions will be quite large. It is mainly reflected in active and passive safety, assisted driving and comfort configuration. The low-middle models are generally configured in these aspects, and the level of assisted driving is relatively low. The high-middle models will be rich and can reach L2 level, and functions such as automatic parking are also matched.

However, in terms of intelligent interconnection, the configuration of each version of the car is the same, providing the original car and CarPlay/CarLife. The whole system supports functions such as voice recognition of the main and auxiliary driving zones.

All in all, the performance of KIA EV5 in terms of configuration can only be considered quite satisfactory, and there is a big difference between low allocation and high allocation, which is also the consistent strategy of joint venture car companies.

Finally, share with you the dynamic performance of this car. KIA EV5 all uses the multi-link suspension structure before McPherson, which is a common configuration at this price and this level. However, the overall adjustment of the suspension will be more mature. When the speed is lower than 80km/h during actual driving, the support is basically sufficient, and the efficiency of vibration filtering is also relatively high. It is basically a trip to overcome the pit and hurdle, and the experience is good. However, if the speed is faster, such a suspension will be somewhat overwhelmed by the curb weight of 2030kg (long life version) and the efficiency will be reduced.

In terms of power, the maximum power of 218Ps and the peak torque of 310N·m, combined with the characteristics of electric drive, the acceleration of the front and middle sections is relatively good, and with the small body size, it feels a bit like a steel gun when driving. In terms of driving texture, the performance of this car can give a high score.

In addition, KIA EV5 provides a version that can run 720km under CLTC and is equipped with 88.1kWh battery, and a version that can run 530km under CLTC and is equipped with 64.2kWh battery.

Write it at the end

To sum up, KIA EV5 is remarkable for its spacious space, practical detail design, abundant power reserve and excellent driving feeling. Compared with domestic models of the same level, I think the advantages of this car lie in its utilization of space, ingenious design and more advanced adjustment of suspension level. If there is an opportunity, Xiaobian personally recommends that you try this car.

As for why KIA EV5 is so popular and its sales volume is mediocre in the case of distinctive personality and good product strength, Xiao Bian thinks that the main problem lies in the price. At present, the entry threshold of KIA EV5 is 149,800 yuan, but the model that can be bought at this price is a low-profile version, and the overall experience will not be very good. If you want to get a higher configuration experience or have higher requirements for battery life, the budget will be at least 170,000 yuan.

At this stage, spending 170,000 yuan to buy a compact pure electric SUV is indeed something that most consumers will not do. Therefore, Xiao Bian thinks that if Kia EV5 can give a cash discount of 20,000-30,000, the overall cost performance will be much higher. Of course, if the budget allows and there is a car purchase plan, it will not go wrong to take KIA EV5 into consideration, and the car experience it can bring you will not be too bad.

Being the first car in life is a good choice. Here are some reasons for combining product points:

1. Reliability: Jetta is famous for its durable and reliable quality. This is very important for the first car, because you want the car to run reliably and reduce the trouble of maintenance and failure.

2. Economy: Jetta usually has good fuel economy, which is very helpful for daily use and saving money. Especially for people who just started driving, affordable vehicles can reduce the burden.

3. Easy to drive: Jetta’s control is usually simple and easy to use. This is an advantage for novice drivers, so that you can adapt to driving more easily.

4. Repair and maintenance: Jetta has a high penetration rate in the market, so the cost of repair and maintenance is relatively low. Parts are easy to obtain and the maintenance technology is mature, which can reduce the cost of vehicle maintenance.

5. Brand recognition: As a well-known brand, Jetta has a certain reputation and recognition in the market. This may have a positive impact on your car purchase decision, and may be more valuable in future second-hand transactions.

6. Safety: Jetta models are usually equipped with a series of safety functions, such as anti-lock braking system, which can provide a certain degree of safety guarantee.

Of course, the ultimate suitability depends on your personal needs and preferences. When choosing the first car in your life, I suggest you consider your own budget, usage, driving habits and other factors, and make a full test drive and comparison. This will ensure that you choose the vehicle that suits you best.

The highlights of Jetta SUV are: design: the front face of Jetta SUV adopts family-style design elements with high recognition, the large-size air intake grille is more prominent, the lines on the hood are full of power, and the middle plaque enhances the overall sense of movement. The waistline design on the side of the car body is sharp, the decorative board is decorated around the window, the rim design is sporty, the exterior rearview mirror is wide, and the exhaust pipe is more powerful. The tail light of LED light source is used at the rear of the car, and the identification is further improved with the logo and tail light group.

-Interior: The interior design is exquisite, equipped with a 10-inch full LCD central control screen, the overall central control is simple, the steering wheel is light, the function buttons in the car are advanced, the electronic shift lever is younger, and the details are embellished and soft-packed. The seat is wide, the material is made of large-area stitching, and the interior looks more classy.

-Configuration: Jetta VS7 is equipped with basic configurations such as fatigue driving warning, uphill assist, brake assist and front.

-Driving experience: Jetta VS7 is equipped with 1.4T, which is matched with a 6-speed automatic manual transmission, which tends to actively upshift and can reduce fuel consumption. The dynamic response in the high-speed range is more positive. Switching to the sports mode when overtaking or running mountain roads after stepping on the accelerator will increase the power on call and make the dynamic performance more outstanding. The brake control is sensitive, the chassis is soft and hard, and the vibration can be filtered through the bumpy road section, and the driving experience with sports driving mode is better.

　　Speaking of automobile oil, I believe everyone is familiar with it. However, familiarity does not mean that you really understand it. In fact, those things about oil are not simple!

　　Engine oil is also called lubricating oil. If the engine is compared to the heart of a car, engine oil is the blood of the car. Its main functions are lubrication impairment, cleaning, sealing and leakage prevention, rust prevention and corrosion prevention, cooling and damping.

　　At present, the market can be simply divided into mineral oil and synthetic oil according to the different base oils. Synthetic oil can be subdivided into semi-synthetic oil and fully synthetic oil. Mineral oil has the lowest price and the worst performance; Fully synthetic oil has the highest price and the best performance. Theoretically, all vehicles are suitable for fully synthetic oil, but considering the cost of vehicles and the use environment, it is generally recommended that:

　　1. Cars or SUVs with a price of more than 200,000 yuan use fully synthetic oil. Because of its excellent aging resistance, the oil change cycle can be extended to 10,000 kilometers.

　　2. Family cars with a price of 100,000-200,000 yuan are usually used for commuting, using semi-synthetic oil, and the oil change cycle is generally 7,500 kilometers.

　　3. If it is a taxi, a used car or even a vehicle with an engine overhauled, mineral oil can be used, but it should be noted that the shortest oil change cycle is within 5,000 kilometers.

　　In addition to the type of engine oil, you can also choose engine oil according to the engine oil label, of which SAE label is the most commonly used.

　　When you get a bucket of engine oil, look at the lower right corner of the bottle. This "5W-40" is the SAE label, which indicates the viscosity grade of the engine oil. Among them, "W" is the abbreviation of winter, and the number in front of W represents the fluidity of engine oil at low temperature. The smaller this number is, the better the fluidity of engine oil at low temperature, and the better the protection of engine when the vehicle is cold started. Generally speaking, there are four grades of engine oil, namely, 0w, 5w, 10w and 15w, which respectively indicate the minimum working temperature of -35℃, -30℃, -25℃ and -20℃. In other words, if you live in the northeast, choose 0w engine oil to meet your winter use. If you are in Beijing, 5w or 10w engine oil can meet your needs. In addition, the low-temperature viscosity grade is only needed for northerners to buy engine oil, but it is generally not considered in southern cities.

　　40 in "5W-40" indicates the high temperature viscosity grade of engine oil. Generally speaking, there are four high-temperature viscosity grades of engine oil: 20, 30, 40 and 60. The higher the high-temperature viscosity grade, the more viscous the engine oil will be, and the better the engine protection will be when it works at high temperature. If it is a new car or a Japanese and Korean brand car, then you should choose a thinner engine oil; If it is a large-displacement or turbocharged car, it is more suitable to choose a thicker engine oil.

　　In a word, the smaller the number before W, the better, and the bigger the number after W, the better.
