Huawei Mate70 real picture

On November 4, Yu Chengdong, Huawei’s managing director, wrote at 8.58am: "The most powerful Mate in history! See you in November!" Previously, the title of "the strongest in history" was used for the Mate 40.

On November 12, a number of digital bloggers posted pictures of the real Huawei Mate 70, with the iconic three-dig design still on the front. Huawei adopted this design for the first time on the Mate 60 Pro and is currently the only mobile phone manufacturer to adopt this solution.

According to the blogger, in addition to the screen shape, this machine also features a metal frame with a right-angle and chamfered transition design. The larger size of the power button increases the fingerprint recognition area, which means that this model will use side fingerprint recognition.

It is reported that the Huawei Mate 70 series rear camera module will return to the Huawei Mate 50 design scheme, using a large round module and equipped with a periscope four-camera module. In terms of configuration, the Huawei Mate 70 series will come standard with a 1.5K OLED screen, and the rear main camera is a domestic outsole sensor customized by Howell, with a built-in large-capacity battery. The processor should also be the latest model.

Previously, an official picture of a suspected Huawei Mate 70 was circulated online, showing various details of the model and marking the price of 8,599 yuan, but the publisher expressed doubts about the authenticity of the picture.

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."

　　The launching ceremony of biodiesel (B5) made from kitchen waste oil in China Petrochemical Gas Station was recently held in Zhuanghang Gas Station, Fengxian District, Shanghai.

　　Xu Kunlin, deputy mayor of Shanghai, said that the start-up of the pilot project of adding kitchen waste oil to biodiesel B5 at Sinopec gas station is of great significance, which indicates that the "last mile" of resource utilization of kitchen waste oil in this city is about to get through. He demanded that all relevant units continue to deepen the pilot work, oil supply enterprises should ensure the quality of oil products, and relevant government departments should further strengthen the division of labor and cooperation, actively serve enterprises, and lay a solid foundation for the promotion of the whole city next year.

　　Zuo Xingkai, Chairman and Party Secretary of China Petrochemical Shanghai Petroleum Company, said that the "normalization" of biodiesel applied to vehicles can not only eliminate the safety risk of waste oil returning to the dining table, but also help to reduce urban pollution, which is a major event benefiting the country and the people. Shanghai Petroleum has a great responsibility and a glorious mission to get this pilot promotion opportunity, and will do its best to do this low-carbon environmental protection project.

　　At present, Shanghai Petroleum has chosen two gas stations as pilot stations to fill biodiesel for the city’s transportation system and vehicles in specific industries. After a period of operation, it will be evaluated and then gradually opened to social vehicles. During the pilot period, the retail price of B5 biodiesel is 95% lower than that of vehicle diesel, with a discount of 0.30 yuan/liter, which encourages more social vehicles to use biodiesel.

　　It is reported that Shanghai has made it clear that the kitchen waste oil collected by the whole city will be given priority to the bus pilot project. As long as conditions permit, about 30,000 to 40,000 tons of kitchen waste oil produced in Shanghai can be transported to designated units to produce biodiesel. In addition, Shanghai promulgated the Emergency Support Measures for the Collection, Transportation and Disposal of Biodiesel Made from Waste Kitchen Oils, which requires that in case of market failure, the relevant disposal enterprises should be subsidized to ensure their normal operation.
