Recently, 25 models were officially unveiled at FAW Audi dealers, and new cars went on the market. The official guide price was 427,900-656,800 yuan. As an annual redesigned model, the new Audi A6L has been continuously optimized in appearance design, interior configuration and scientific and technological functions, which has stabilized its market competitiveness in medium and large cars. It stands to reason that there will be no obvious price fluctuation. However, with the official arrival of the first batch of new cars, we found that the preferential strength of 25 Audi A6L models in the terminal market is also relatively acceptable. Under the condition of meeting the local license, and with the consumption of in-store insurance and in-store loans, it can basically reach a discount of 127,900 yuan, and the discounted price can be as low as 300,000 yuan.

The overall design of 25 Audi A6L models is basically the same as that of 24 models. The front face still adopts the classic hexagonal air intake grille, and the interior adopts the line chrome trim, and the headlight configuration in matrix style is standard, which has been partially upgraded on the basis of the previous generation. However, the elegant appearance of the 25 Audi A6L is cancelled, which means that the new model no longer provides the front face with multiple banners, which makes the design more sporty and fashionable. On the side of the car body, the dimensions of 25 Audi A6L cars remain unchanged, and they are still slender medium-sized and large-sized cars. Together with LED dynamic taillights, the overall design is coordinated and the business sense is relatively strong. There is almost no change in the rear of the new car, and LED taillights with dynamic turn signals and chrome-plated decorative strips surrounding the rear continue to be used.

From the interior point of view, the 25 Audi A6L models are still similar to the previous generation models, and this set of interiors can be said that there has not been much change in recent years. The full LCD driving computer in front, the embedded central control large screen and the 8.8-inch air conditioning control screen are all familiar designs for consumers. In addition, three multifunctional leather steering wheels, electronic gear handles and leather seats can be equipped with heating and ventilation.

It is worth noting that 25 Audi A6L models have been added, and the models with low and medium configurations are also equipped with panoramic sunroof configuration and lane departure warning system. In addition, the 25 Audi A6L also upgraded the electric steering wheel, the front headrest, the accelerator and the brake pedal with chrome decoration. From this point of view, the addition is still ideal. However, the new car has been downgraded in terms of seat material, and the suede material of the original high-profile model has been changed to imitation leather seats, and the quality monitoring system has also been cancelled. More crucially, the reaction speed of the 25 Audi A6L cars is slower than before, because the 5G signal is replaced by the 4G network, the network speed is slower and the distribution is obviously reduced. However, it is precisely because the 25 Audi A6L models have been increased and decreased, and the appearance adjustment is not big, which leads to the preferential strength of more than 100,000 yuan when the new car arrives at the store.

In terms of space performance, the 25 Audi A6L models have always been excellent, and the body size has not changed. It is still 5050mm long, 1886mm wide, 1475mm high and 3024mm wheelbase. Even if a lot of young sports elements are added to the change, there is no discount in terms of space comfort. Of course, the only flaw is that the head space in the back row is slightly smaller than that in the previous generation, but it will not be affected in terms of daily use, and it is spacious enough for sitting or pulling things.

From the point of power system, 25 Audi A6L still have 2.0T high and low power versions with output horsepower of 245Ps and 190Ps. In addition, there is a 3.0T 6-cylinder engine with 48V light mixing system with output of 340Ps, but most consumers will still choose 2.0T power system. In addition, 25 Audi A6L models are still equipped with a 7-speed wet dual-clutch gearbox, which gives consideration to dynamic response and fuel economy. If consumers buy a 2.0T high-powered version, they will also be equipped with a timely four-wheel drive system. As far as the same-class models at this price are concerned, there are really not many sedan cars equipped with four-wheel drive. Not only is there no such configuration, but there is not even one. This is also a bright spot for 25 Audi A6L models.

Generally speaking, the 25 Audi A6L models are further enhanced in luxury, intelligence and practicality, which is attractive to consumers in terms of design, configuration upgrade and power performance. More importantly, the diving in price really surprised me. However, the 25 Audi A6L models are also the last generation products, because the new models will be listed soon and renamed as. Therefore, it is time for cash to bargain-hunting.

In the automobile market, the choice of gearbox has always been the focus of consumers’ attention. As two mainstream transmission types, DCT (powershift) and AT (Automatic Transmission) have their own advantages and disadvantages. So, how to choose? This article will give you a detailed analysis from many aspects.

First, understand the basic principles of DCT and AT.

The core principle of DCT, namely powershift, is to split the manual gear into base gear and even gear, and then equip two clutches to drive them respectively. This design makes the shift speed faster and the power output more direct. AT, the automatic transmission, automatically shifts gears through the hydraulic torque converter and multiple pairs of planetary gear sets, making driving more convenient.

Second, the size and transmission efficiency comparison

In terms of size, DCT has obvious advantages Take ZF’s 9AT as an example, its length is 521 mm, while Volkswagen’s DK500 powershift is only 400 mm.. This means that in the same space, DCT is easier to arrange and provides more possibilities for vehicle design.

In terms of transmission efficiency, DCT also performed well. The transmission efficiency of dry powershift is about 90%-95%, which is close to manual gear. The wet powershift is slightly lower, accounting for 86%-92%. The transmission efficiency of AT transmission is generally in the range of 82%-90%. This means that under the same conditions, DCT can give full play to the power of the engine.

Third, driving experience and fuel consumption performance

DCT has fast shifting speed and direct power output, which brings more radical driving experience to drivers. At the same time, because of its high transmission efficiency, DCT is also relatively good in fuel consumption performance. AT is famous for its stability and smoothness, which is suitable for drivers who pay attention to comfort and convenience.

Fourth, reliability and maintenance costs

Regarding reliability, DCT and AT have their own advantages. As long as the heat dissipation problem of DCT is solved, its performance is better than that of AT in all aspects. However, in practical use, AT is trusted because of its mature and stable structure. In terms of maintenance cost, due to the complex structure of AT, once a fault occurs, the maintenance cost is relatively high; DCT, on the other hand, is relatively simple and has low maintenance cost.

5. How to judge whether the gearbox matches well or not?

When choosing a car, it is very important to judge whether the gearbox matches well or not. You can experience the shifting logic, frustration and noise of the gearbox through the test drive. A good gearbox should have smooth shifting process, low sense of frustration and good NVH performance.

VI. Suggestions on product positioning and selection

In the automobile market, different types and different price models are often equipped with different types of gearboxes. Generally speaking, high-end models prefer to use AT gearbox to reflect their quality and stability; The models that pursue sports style and cost performance are more likely to choose DCT gearbox. Therefore, when choosing, you need to make a decision according to your actual needs and budget.

To sum up, DCT and AT have their own advantages, and which gearbox to choose depends on your personal preferences, driving habits and actual needs. If you pursue aggressive driving experience and high fuel consumption performance, DCT is undoubtedly a better choice; And if you pay attention to comfort and convenience, then AT is more suitable for you. When making a decision, please be sure to fully understand the advantages and disadvantages of various gearboxes and weigh them according to your actual situation.

　　Recently, it is reported that Gree Electric and Weimar Automobile will carry out in-depth cooperation in intelligent related fields, such as intelligent manufacturing, intelligent interconnection between vehicle owners and so on, as well as vehicle manufacturing-related and high-end equipment output.

　　Gree said that the cooperation between Gree Electric and Weimar Automobile will also explore the possibility of cooperation in channels. According to the relevant person in Gree Electric who told the Securities Daily reporter, Gree has reached cooperation with many automobile companies such as FAW-Volkswagen, SAIC-GM and Dongfeng Honda, and the exploration path is basically similar.

　　According to insiders of Gree, Dong Mingzhu has always maintained a strong interest in the automotive field, and has promoted the cooperative relationship between Gree and car companies for many times.

　　Does the cooperation between Gree and Weimar Automobile further enter the overall manufacturing related industries, which means that Dong Mingzhu is one step closer to the realization of its "dream of building a car"?

　　Gree officially entered the whole vehicle manufacturing?

　　Recently, the cooperation between Gree Electric and Weimar Automobile has attracted much attention from the outside world. However, in fact, Gree Electric has held hands with many automobile companies.

　　It is understood that most of the projects and workshops of FAW-Volkswagen’s manufacturing bases in Chengdu, Foshan, Changchun and other places have adopted Gree’s high-efficiency centrifugal chillers. Gree also provided systematic solutions for the refrigeration station project of the comprehensive station building of the third base of SAIC-GM-Wuling Automobile and the production capacity expansion project of Dongfeng Honda Automobile Co., Ltd. in Guangzhou.

　　However, unlike the previous cooperation between the two parties mainly in the fields of automobile air-conditioning and central air-conditioning, the cooperation between Gree Electric and Weimar Automobile will be carried out in the aspects of vehicle manufacturing and high-end equipment output, and the banner of intelligent interconnection between car owners will be played.

　　Zhang Jianfeng, Deputy Secretary-General of china national household electric appliances commercial association, said in an interview with Securities Daily: "With the coming of the 5G era, many enterprises are discussing how to realize the interconnection of industry and technology. However, for the cross-border people in the automobile industry, it is still difficult to enter this field with high threshold, and cooperation has become the way for them to open up market space. Gree has been laying out in the fields of smart home and intelligent manufacturing, and has accumulated rich technology and resources. Cooperation with Weimar Automobile means that it has a deeper involvement in the automotive field, but Gree’s layout of intelligent manufacturing needs to be further spread. "

　　However, this time, does the cooperation between Gree and Weimar Automobile mean that Gree will fully enter the field of vehicle manufacturing?

　　In this regard, Jia Xinguang, executive director of china automobile dealers association, said in an interview with the Securities Daily: "At present, the cooperation between Gree and Weimar Automobile may be more in parts, intelligent manufacturing and intelligent systems, which is conducive to further promoting the intelligence of new energy vehicles, but it is difficult for the two sides to truly cooperate fully on the whole vehicle."

　　He believes: "In recent years, many companies have flooded into the field of new energy vehicles, but they have no clear understanding of the industry. The threshold of automobile manufacturing industry is high, which requires enterprises to continue research and development, and research and development can not stop, but also to build a large area of network, enterprises must continue to invest a lot of money and resources. However, among the newly entered enterprises, there are not many that can really make achievements in the automobile industry, and even many new entrants have died down. "

　　Will the enthusiasm for building a car be short-lived?

　　The timing of this cooperation is also critical, just during the period when Gree’s major shareholder is brewing Gree Electric’s equity transfer.

　　At present, the equity transfer has not officially landed, and there is still great uncertainty about who will take over in the future. At present, all parties are waiting for the answer.

　　"Although from this public information, we have not seen the specific details of the cooperation between Gree Electric and Weimar Automobile and the amount of funds involved, we can see the future direction of Gree Electric, which is still expanding in the field of smart cars in an attempt to expand the territory of intelligent manufacturing industry. Even if new shareholders come in, Gree’s future development path in the direction of intelligent manufacturing and car networking will not change much." Strategic analyst Hong Shibin told the Securities Daily reporter.

　　Gree Electric insiders said: "No matter how the shareholding structure of the company’s shareholders changes in the future, Gree Electric will still follow the existing planning route, and there will be no obvious changes. The future layout of the company is continuous and forward-looking."

　　Jia Xinguang believes: "At present, most cross-border people and traditional car companies jointly explore the potential market space in marginal industries, and it is still difficult to enter the core manufacturing field, but future cooperation will be the normal state of the industry."

Wow, fellow riders! Today, Xiaobian is going to give you a big story! You know what? At the just-concluded 2024 Tianjin Auto Show, the shoulder of our domestic luxury brand brought a heavy new car, which is the legendary "Guoya"! This is no ordinary new car, but a super luxury car that wants to wrestle with Mercedes!

Having said that, I can’t help but think of a paragraph I brushed in my circle of friends a few days ago:

"Lao Wang: I just bought a new car, which is more expensive than that!
Lao Li: Wow, did you buy Maibakh?
Lao Wang: No, I bought it! "

Yes, that’s it! Our domestic luxury car is finally going to make a big splash in the high-end market!

But wait, is it really that good?

Let’s take a look at the ins and outs of this "elegant instrument of the country"!

Remember watching the military parade when I was a child, the majestic red-flag car? That’s a special car for state guests! But now, as long as you pay 20 thousand yuan, you can book a red flag Guoya! What kind of fairy operation is this?

Actually, it all starts with the transformation of Hongqi brand. The former red flag, like a cold goddess, can only be seen from a distance and cannot be used for fun. But now? It has transformed itself into a big sister next door, kind but noble. Isn’t this change the epitome of the development of China’s automobile industry?

Speaking of Guoya’s motivation, that would be great. 4.0T hybrid system with maximum power of 360kW and maximum speed of 250km/h.. As soon as this data came out, my first reaction was: Is this allowed to take off?

Imagine that you are cruising Guoya on the highway, and your friends next to you are still worried about saving fuel. What about you? There is not only the surging power brought by large displacement, but also the energy-saving blessing of hybrid system. This is simply the rhythm that both fish and bear’s paw want!

Yan value is justice, which is more appropriate for Guoya. The body length of 5.3 meters, the large-size vertical banner with domineering side leakage and the chrome-plated front grille, as well as the red flag that can be lifted and lit, are simply moving works of art!

The interior is even more magnificent. Violet with ultra-white, terracotta brown with graphite black, spring wild green with rain ash ….. How does this color scheme sound like reading a poem? It’s probably more comfortable to sit in than a five-star hotel!

To tell the truth, when I saw Guoya going to compete with Mercedes-Benz Maibakh S-Class, my first reaction was: Are you kidding? But on second thought, why not?

Isn’t our high-speed rail in China already ahead of the world? Which field of mobile phones and home appliances is not killing foreign brands crying? Why can’t the automobile industry work? Besides, Huawei can build a car. What’s wrong with an old brand like Hongqi building a luxury car?

Some people say that the emergence of Guoya will stir up a pool of spring water in the luxury car market. But I think the water in this pool has already been turned upside down, okay?

Not to mention showstopper like Tesla, even sports car brands like Porsche and Ferrari are building SUVs. In this era when everyone wants to be online celebrity, how can there be a peaceful life in the luxury car market?

But then again, the emergence of Guoya may really bring some new possibilities to this market. After all, the label Made in China has changed from cheap to synonymous with high quality. Why not luxury cars?

Finally, I want to say that no matter whether Guoya can succeed in the end, its appearance is something to celebrate. Because it represents an important breakthrough in China’s automobile industry and represents that we are moving from a big automobile country to a powerful automobile country.

Then the question is coming. If you had a choice, would you buy Guoya or an imported luxury car? Welcome to leave a message in the comment area, let’s discuss this topic together!

Yes, BYD Seal EV has sentry mode. This function is mainly used for vehicle safety protection and theft prevention. When the vehicle is stationary, if abnormal behavior or illegal intrusion is detected around it, the vehicle will automatically take photos and videos and send an alarm to remind the owner. At the same time, the vehicle will automatically lock and start the anti-collision system to prevent further danger.

　　 As a programmatic document leading China’s social and economic development in the next five years, the "Thirteenth Five-Year Plan" has attracted much attention from the society since its promulgation. Among them, 12 articles with 25 chapters, such as implementing innovation-driven development strategy, building a new development system, optimizing modern industrial system, fully implementing poverty alleviation and strengthening socialist spiritual civilization construction, are all related to the Internet, and "expanding network economic space" is listed as a separate article in the outline, which is the first time that China’s five-year plan has planned the development of the Internet with such high specifications.

　　 China Netcom invited Wang Yukai, a member of the National Informationization Expert Advisory Committee and a professor of the National School of Administration, to visit the interview room to talk about his views on the weight of the Internet in this planning outline and the road map for China to implement the strategy of strengthening the country through the Internet in the next five years.

　　 What is the significance of "expanding the network economic space" being written into the outline?

　　 The article "Expanding the Network Economic Space" in the "Thirteenth Five-Year Plan" contains four chapters: building a ubiquitous and efficient information network, developing a modern Internet industry system, implementing the national big data strategy, and strengthening information security.

　　 In the Internet era, new technologies such as cloud computing, big data, mobile Internet and Internet of Things have been loaded, and the Internet can be deeply integrated with various industries, with many new formats and new values created. Many new growth points in generate have also spawned a new concept — — Network economy. In view of the four development directions of "expanding the network economic space" in the "Thirteenth Five-Year Plan", Wang Yukai believes that they have different meanings:

　　 Constructing ubiquitous and efficient information network — — "Without a strong network infrastructure as a support, a network power will have no foundation."China’s largest network scale and the number of netizens in the world, underdeveloped broadband network and a large-scale Internet industry have very high requirements for network infrastructure; Some experts predict that in the future, the Internet of Things can cover the Internet, and this form of connection between things, people and things, and people also needs high-speed ubiquitous network infrastructure construction as a guarantee.

　　 Develop a modern Internet industry system— — The Internet industry system now includes two aspects: consumer Internet and industrial Internet. Alibaba and JD.COM are representative enterprises that consume the Internet, and the "internet plus" action plan and the "Made in China 2025" action plan are aimed at building the industrial Internet. Internet can be deeply integrated with many industries, such as internet plus Finance, internet plus Manufacturing, Internet+Agriculture, internet plus Transportation, Internet+Education … … "If the industrial system relies on the Internet, it will bring great changes from production, circulation to consumption."

　　 Implementing the National Big Data Strategy — — "Raising big data into a national strategy has a lot to do with the value of big data itself."战略上大数据是一种数据资本；处理方式上它是用云计算发掘、处理的一种新技术；价值上社会、政府、数据挖掘公司都可以通过数据不断创造、产生新价值。

　　 强化信息安全保障——中国在互联网安全、国家安全保障还存在短板，除了高度重视堵住制度漏洞，打造互联网安全和国家安全体系还在于关键技术的自主可控。全国12亿手机用户，包括6亿多智能手机用户，绝大多数只用苹果和安卓两个手机操作系统，电脑则主要是微软系统。2014年我国光进口芯片就花了八千亿美元，远远超过进口石油花的钱。只有握住关键点，国家安全、互联网安全才能有所保障。我们要借助互联网经济的大框架，构建网络安全产业的保障体系。

　　 “网络强国”的实现有几重标志？

　　 2014年，最高领袖总书记担任中央网络安全和信息化领导小组组长。他在领导小组第一次会议中指出：我国已成为网络大国。同时也要看到，我们在自主创新方面还相对落后，区域和城乡差异比较明显，特别是人均带宽与国际先进水平差距较大，国内互联网发展瓶颈仍然较为突出。同时指出，没有网络安全就没有国家安全，没有信息化就没有现代化。

　　 Wang Yukai said that we have made great achievements in the development of the Internet in recent years. The number of netizens in China is close to 700 million, ranking first in the world, but the internet penetration rate is less than 50%, which is far from developed countries. The construction of network infrastructure is constantly increasing, and China Mobile, China Telecom and China Unicom are constantly laying networks throughout the country; High-speed broadband extends to villages and towns; There have been such internationally renowned enterprises as Alibaba, JD.COM, Baidu, Tencent, Sina, Huawei, ZTE and Lenovo. Network scale, network users, mobile phone penetration rate, network industry, network economy, including the level of social, government and enterprise informatization have all reached a relatively large scale.

　　 But we are not a network power yet. Network powers have the following signs: the Internet and Internet of Things infrastructure are at the world-class level — — Including network scale, broadband penetration rate, ubiquitous broadband, etc. There are a wide range of Internet applications — — Whether it is enterprise, government, social application, consumer Internet or industrial Internet, it should be widely used by all industries and ordinary people. Have the right to speak on the Internet in the world — — Including the country’s greater right to speak in the process of formulating Internet rules and participating in world cooperation; Have a clear Internet development strategy and plan — — Including the internet of things, big data strategy, network power strategy and relatively strong network security and national security protection capabilities. From these aspects, we still have a certain distance from the goal of becoming a strong country in the network.

　　 How to promote the strategy of strengthening the country by network to fill the shortcomings of people’s livelihood?

　　 The "Thirteenth Five-Year Plan" also includes 100 major projects and projects that the country plans to implement in the next five years. After preliminary combing, major engineering projects related to network security and informatization development include national cyberspace security, implementation of "internet plus" modern agriculture, cultivation of the fifth generation mobile communication (5G) as a new growth point, construction of high-speed and large-capacity optical communication transmission system, construction of Internet of Things application infrastructure and service platform, support for the construction of public cloud service platform, layout of cloud computing and big data center, acceleration of the construction and application of national unified e-government network, creation of an international channel for e-commerce, and construction of national network security and confidentiality technical guarantee.

　　 Wang Yukai said that nearly ten of these major projects and projects involve new Internet technologies, and if they are finally completed, we will be closer to the realization of the goal of becoming a strong country in the Internet. However, in addition to infrastructure construction and national security, we should also use the development of the Internet to benefit people’s livelihood. Through the application of the Internet in the fields of people’s livelihood such as medical care, education and social security, the development of the whole Internet industry will be stimulated.

　　 For example, 56 of the 86 counties in Gansu Province are poverty-stricken counties, and there is great pressure to get rid of poverty. For this reason, they have established an accurate information platform for poverty alleviation, and they can see the poverty situation of any family in the province in front of the computer. If a family was lifted out of poverty last year, but returned to poverty because of illness, it is required that the platform be accurate to who the family returned to poverty because of illness. This platform also makes use of information network technology for how to implement poverty alleviation funds and how to correct mistakes.

　　 What aspects should we make efforts to implement the strategy of strengthening the country by network?

　　 Wang Yukai believes that in order to ensure the smooth progress of the strategy of strengthening the country by network, the following aspects should be adhered to in the future:

　　 The state has issued a reasonable plan and strategy, and standardized it with a unified and authoritative strategic goal of strengthening the country through the Internet.Let the formulated strategy be implemented relatively, and there are more specific operational paths.

　　 Local governments should adjust measures to local conditions and implement relevant planning strategies.All localities can decide the key development areas according to the existing foundation, industrial form, positioning in the national market and industrial advantages to avoid repetitive construction.

　　 Infrastructure construction should not only play the role of the state, but also play the role of the market with the help of the market.If government departments make decisions and engage in construction alone, it may lead to waste of resources. Introducing PPP (government-social capital cooperation) mode in the construction of network facilities, big data centers and network security guarantee system, with the help of government and market, the major projects can be really useful in the future.

　　 Reform unreasonable system and mechanism, and remove obstacles to the application of information technology.Because the application of information technology and internet technology in government, enterprises and society may be restricted by traditional institutional mechanisms, and at the same time, departmental barriers and administrative barriers make communication barriers between institutions, forming information islands. Therefore, we should use the power of reform to remove the obstacles of unreasonable institutional mechanisms to the application of information technology, big data mining and application, and promote the implementation of the strategy of strengthening the country through the network.

　　Xinhua News Agency, Washington, August 18thBiden: Running for the presidency three times in half a century.

　　Xinhua News Agency reporter Deng Xianlai Xu Jianmei Sun Ding

　　I struggled with stuttering as a child, and later lost my wife and children due to car accidents and illness. I have been in politics for nearly 50 years and ran for the US president three times …

　　On the 18th, former US Vice President Joe Biden, who will turn 78, was formally nominated as the Democratic presidential candidate in 2020 at the Democratic National Congress. In the first two challenges, he stopped at intra-party competition; This time, can deus ex win?

　　This live video shot on August 18th shows Joe Biden celebrating after being nominated as the US Democratic presidential candidate in 2020. Xinhua News Agency reporter Liu Jie photo

　　Veteran politicians are ill-fated

　　Biden was born into a middle-class family in Pennsylvania in November 1942. When he was a teenager, he moved to Delaware with his family. He studied at the University of Delaware and Syracuse University and obtained a law degree.

　　Biden once wrote in his autobiography that when he was a child, his elders often discussed international and domestic politics, and he couldn’t wait to participate, which laid the foundation for his political career. After graduating from Syracuse University in 1968, Biden worked as a lawyer and became active in Delaware politics as a democratic party member. In 1972, he was elected to the Delaware Senate, becoming one of the youngest senators in American history.

　　During his 36-year career as a federal senator, Biden served as chairman of the Senate Judiciary Committee for a long time and twice as chairman of the Senate Foreign Relations Committee. He ran for president twice in 1988 and 2008, but neither was nominated by the party. In the 2008 general election, Biden withdrew from the intra-party competition and became the running mate of Obama, who was later elected president, and eventually became the vice president of the United States, and was re-elected four years later. Long-term political experience has enabled Biden not only to establish a deep foundation and extensive contacts, but also to accumulate enough experience in internal affairs and diplomacy.

　　Biden had many setbacks in his life. When he was a child, he was laughed at by his classmates for stuttering, and finally he overcame the language barrier by reciting long poems in front of the mirror. A few weeks after he was elected to the Senate for the first time, his wife and youngest daughter were killed in a car accident and their two sons were seriously injured. He finally decided to take office in the Senate after being persuaded by colleagues and friends. In 2015, his son bo Biden died of brain cancer, and he suffered a heavy blow again. Biden’s running mate Kamala Harris was Bo’s close friend, and this relationship was one of the reasons why he finally chose Harris.

　　The policy "turns left" and its implementation is doubtful.

　　The National Congress of the Democratic Party adopted a new party program on 18th, covering COVID-19 epidemic, economy, medical insurance, race, diplomacy and other fields, which was generally "moderate" and absorbed some ideas of "progressives" within the Party. This reflects Biden’s policy objectives.

　　The epidemic situation in COVID-19 and ethnic issues are important issues in this year’s general election. In response to the epidemic situation in COVID-19, the new party platform proposed to expand the scope of testing, strengthen contact tracking, and provide free testing, treatment and vaccines. Biden, who usually wears masks during the epidemic, also called for a national mandatory mask-wearing order. On the issue of race, Biden promised to solve the problem of "systematic racism" in American society within 100 days after taking office. He also took solving ethnic problems as part of his economic recovery plan, and promised to increase capital investment in education, employment, income, housing, supporting small businesses and other fields to ensure equal opportunities for ethnic minorities.

　　However, some American media have pointed out that Biden has refused the Democratic Party to turn left for decades, but now he has absorbed the "progressive" proposition for the sake of "unity". The current policy must be bolder than that when he was a senator and vice president. "This is a contradiction in itself." There may be a gap between his campaign promise and actual implementation.

　　The polls are ahead, but there are shortcomings.

　　Since the presidential nomination was locked in April, Biden’s poll support rate in the national and key swing States has been ahead of President Trump seeking re-election. According to a poll conducted by the Pew Research Center in the United States in June, compared with Trump, voters think Biden is more peaceful, more honest, more concerned about the needs of ordinary people and a better role model. On policy issues, Biden is less recognized than Trump in economic policy, and is more optimistic in justice, foreign policy, epidemic response, ethnic issues, national unity and so on.

　　However, it is worth noting that the poll conducted by the Pew Research Center from July to August showed that more than half of Biden supporters expressed their support for Biden because they opposed Trump, which was much higher than other options such as leadership, personality and policy stance.

　　Despite the lead in the polls, Biden is not without shortcomings. The first is the age issue. If Biden wins, he will become the oldest president of the United States when he was first elected. Polls show that about one-third of Biden’s supporters are worried about his old age and health.

　　Secondly, Biden’s current policy stance shows more signs of "turning left" than that in the pre-selection stage. The Trump campaign team is taking advantage of this in the near future and spares no effort to portray him as a "tool of radical left wing".

　　Thirdly, although Biden plays the "Unity Card", his ability to mobilize the enthusiasm of voters still lags behind Trump. However, affected by the epidemic, it is difficult for Biden to hold large-scale rallies and campaign activities. The current ratings of this year’s Democratic National Congress, which is mainly presented in the form of online live broadcast, are not as good as four years ago, which may make it more difficult to make up for this shortcoming.
