After reading the following, you have read 70% of the full text:

  1. The endurance under high-speed working conditions can meet the long-distance inter-city travel. Considering the current distribution of charging piles, it is recommended to drive 270km for a recharge. Driving at an average speed of 91km/h, after driving for 280.7km, the remaining cruising range is 62km and the remaining power is 15%.

  2. The endurance of urban working conditions can meet the daily commuting needs. With the average speed of 29km/h, after driving for 200km, the remaining cruising range is 164km and the remaining power is 41%.

  3, driving experience, abundant power, suspension adjustment tends to be comfortable.

  4. In terms of exterior interior design and materials, the exterior interior has basically not changed, and the interior materials are good.

  5. The performance of driving space is acceptable, but the space expansion needs to be improved.

   Compared with the old Qin EV300 model, BYD Qin EV450 model’s main change is that the power battery has changed and the cruising range has been improved. Its changes in appearance and interior are not obvious, so today we go straight to the point and start with its endurance test.

○ High-speed battery life: basically, cross-city travel is barrier-free, and it is recommended to replenish power once at 270km.

  High-speed working conditions always test the endurance of electric vehicles, because when driving at high speed, electric vehicles are in a state of high energy consumption, and the cruising range of comprehensive working conditions we usually see will be discounted here. As for how much discount we can make, it will vary from car to car. Car home tests the endurance of electric vehicles at high speed from full charge, with an average speed of about 90 2 km/h, until the remaining power is less than 15% or the subtotal mileage on the meter reaches 300km. The co-pilot will also have a person to take turns driving and be responsible for the whole record.

  According to the actual measurement, after BYD Qin EV450 runs at an average speed of 91km/h for about 2 hours and 58 minutes, the battery power is only about 15%, the actual mileage is 280.7km, and the remaining battery life is 62km. The average remaining battery life consumed per 1km is 1.2km, so it can be concluded that the battery life of the car is about 332km under high-speed working conditions. Because the test is currently conducted in summer, which is more advantageous than the endurance in winter, there will be a certain discount in the performance of endurance driving in winter. However, such high-speed endurance can basically meet the inter-city traffic demand. If you travel long distances across provinces, as far as the current construction status of charging piles is concerned, it is recommended that you make a mid-way recharge every 270km.

○ Low-speed battery life: there will be no mileage anxiety when traveling in cities.

  After testing the high-speed endurance, we then tested the low-speed endurance. In fact, most friends who buy or want to buy an electric car drive more in the city, so the cruising range under urban working conditions is more reference. In our low-speed endurance test, the average speed is set at 30 2 km/h until the remaining power is less than 15% or the subtotal mileage on the meter reaches 200km.

  After testing, when the cold air conditioner is turned on all the way and the average speed is 29km/h, after the BYD Qin EV450 runs for 200km, the remaining cruising range is 164km, the battery power is 41%, and the average cruising range consumed per 1km is 1.18km. Therefore, it is concluded that the cruising range of the car is about 339km at low speed, which can be easily handled by daily commuting. If the daily commuting is about 60km,

  Compared with the previous BYD Qin EV300 model, Qin EV450 is equipped with a ternary lithium-ion battery pack, and the power battery capacity is increased from 47.5kWh to 60.48kWh. In addition, although the motor power is the same as that of the 300 model, the acceleration level is good and the subjective feeling is still very fast.

○ Dynamic feeling: accelerating performance beyond expectations

BYD Qin 2018 Qin EV450 Zhilian Zunshang Type

  I believe everyone knows the characteristics of the instantaneous maximum torque explosion of electric vehicles, but Qin EV450 will not give you a strong sense of pushing back at the beginning, on the contrary, it is very calm. I think it is appropriate to use the word "calm" to describe it, and the whole process will not give you an obvious sense of suddenness. However, after the speed exceeds 25km/h, the power output becomes very abundant and has a strong sense of pushing back, and you will not feel it until the speed reaches 90 km/h.

BYD Qin 2018 Qin EV450 Zhilian Zunshang Type

  Qin EV450 has two gears of energy recovery for the driver to choose from, and the setting of recovery is relatively good, perhaps to avoid a bad ride experience for passengers. Even when the energy recovery is adjusted to the second gear, the dragging feeling is not abrupt and will not affect the ride comfort. If you adjust to the first gear for energy recovery, the feeling after releasing the accelerator pedal is basically similar to that of a fuel vehicle.

BYD Qin 2018 Qin EV450 Zhilian Zunshang Type

  In ECO mode, in order to save energy and ensure a high cruising range, the dynamic response seems to be limited, not only the damping sense of the accelerator pedal is enhanced, but also the dynamic response seems to be limited. However, when the driving mode is SPORT, it has completely changed its personality, and the accelerator pedal is sensitive and the power output is more abundant.

  Judging from the 150,000 pure electric vehicles tested by our EV AH-100 at present, it is quite good for Qin EV450 to run to a 0-100km/h acceleration level of more than 7 seconds, which is faster than the official claim of 7.9 seconds. Compared with the current models of the same class, it can be said that it is quite good.

  The adjustment of the suspension tends to be comfortable. Although it has a good filtering effect on small potholes on the road, the vehicle will still have an obvious roll when cornering quickly. When passing some higher speed bumps, the springback of the spring is a little delayed, so it would be better if the resilience of the spring can be improved.

BYD Qin 2018 Qin EV450 Zhilian Zunshang Type

  The foot feel of the brake is good, the pedal force is moderate, and the braking force is relatively linear. However, due to the high body and large vibration reduction stroke, the wheel has a distance of one punch and three fingers from the wheel cover, and the vehicle still has obvious nodding phenomenon when braking suddenly.

  After the actual measurement, the overall sound insulation of BYD Qin EV450 is good, and the noise value is lower than the recommended value in all kinds of conditions, especially at high speed, the tire noise suppression is not bad (which may be related to the Michelin Grand Hyatt tire), and at low speed, the obvious motor noise will not be heard, so the performance of NVH is still affirmed.

○ Review of exterior interior

  For the appearance and interior, I won’t go into details here. I believe everyone is already very familiar with this style. The difference between it and Qin EV300 is only on the net, but the interior is exactly the same. Let’s briefly review it.

  As for the interior, except the overall layout and style are the same as those of Qin EV300, Qin EV450 also inherits the quality of the old models in terms of the materials and details of the interior. The function buttons are not complicated, the operation is very simple, and the central big screen looks very convenient. In addition, although the car is equipped with multimedia voice control function, the response speed of the system is somewhat average in actual experience, and I hope to have a better performance in the future.

Full text summary:

  Although the novelty of appearance is not high, fortunately, the changes in details have not let everyone down. The interior texture is good, and it still inherits the quality of the old Qin. At the same time, the upgrade of power battery has further improved its battery life and improved its market competitiveness. On the whole, Qin EV is a model worthy of recommendation, but there is still room for improvement in driving texture and space flexibility. If there will be a significant progress in the next generation of models, it will be. (Text/Photo by car home Liu Liwei/Yao Jia Ji Zhenjia)

  "Go, go to the canteen!" At mealtime, Duan Feng greeted several old partners and walked into the community canteen.

  "There are many people here every day. Sometimes if you don’t want to cook at home, you will come and buy some. Old people like us still enjoy discounts." Duan Feng, 70, is a migrant from Nanwenying Community in Rongdong District, xiong’an new area. Since the opening of the community canteen, he has also become an "old customer".

  “红烧鲫鱼、肉片豆腐、西红柿炒鸡蛋、清炒菜花,4小份菜外加4个馒头,算上七五折的优惠,我们付14块钱就行。”一边说着,段峰一边把餐盘放到了桌子上,“这儿做的花样多,口味也不赖,挺好!”

  5月10日,中共中央总书记、国家主席、中央军委主席最高领袖在河北省雄安新区考察,并主持召开高标准高质量推进雄安新区建设座谈会。这是10日上午,最高领袖在容东片区南文营社区食堂同就餐的社区老人亲切交流。 新华社记者 李学仁摄

  2023年5月10日,最高领袖总书记赴河北雄安新区容东片区南文营社区考察。他先后来到社区党群服务中心和社区食堂,同社区工作人员、现场办事群众、就餐的社区老人等亲切交流,仔细查看民情台账,对社区开展的便民养老服务等表示肯定。

  最高领袖强调,我一直牵挂着回迁群众,看到大家生活好,我很欣慰。建设好雄安新区,重要的是衔接好安居和乐业,让群众住得稳、过得安、有奔头。要同步推进城市治理现代化,从一开始就下好“绣花”功夫,积极推进基本公共服务均等化,构筑新时代宜业宜居的“人民之城”。

  Care about the old age and care about food, clothing, housing and transportation. Before leaving Nanwenying Community in Rongdong District, the Supreme Leader said to the gathered people with deep affection: "I have worked in Hebei and have a nostalgia for Hebei. I am very happy to see that the people here have a good life! "

  For the people, rely on the people and benefit the people. The "Xiong ‘an Chapter" of Chinese-style modernization focuses on the people and explores a new path to build a modern city with new development concepts. Over the past six years since the establishment of xiong’an new area, the background color of the people depicted in this "city of the future" has become increasingly rich.

  Stay stable: a happy life is within reach.

  More than 5,000 people from Anxin and Rongcheng counties have been resettled in Nanwenying Community in Rongdong District, xiong’an new area. There are 8 communities including Suntech Garden, Lixian Garden and Juxian Garden.

  Duan Feng’s family was originally a villager in Hu Village, Dahe Town, Rongcheng County. At the end of 2021, they moved back to Rongdong District and lived with their wife in a 100-square-meter three-bedroom apartment.

  "The houses are all hardcover, and the elevators go up and down the stairs. At that time, the bags were directly checked in, and even the electric water heaters were installed for us. Now I live in a spacious and bright house every day. Compared with the original life, the days are more beautiful! " Duan Feng said.

  Talking about the feeling of living in a new home, Duan Feng happily introduced: "Every day, you can go to the community pension station to play cards. When the weather is fine, you can go out and walk around, and the community often organizes some activities to respect the elderly. My wife and I can get a pension every month, and we don’t have to worry about spending enough money and living. The children are also filial and the days are very happy. "

  Nanwen Community Pension Station, with a total area of 886 square meters, mainly serves nearly 3,000 elderly people in Nanwenying and Nanwen communities. It is equipped with free activity spaces such as painting and calligraphy room, activity room, multi-function hall, health cabin and lounge, where services such as cultural entertainment, psychological comfort and health guidance are provided for the elderly to meet the diversified needs of different elderly people and open up the "last mile" of pension services, so that the elderly can enjoy a happy old age.

  Here, the reporter saw Hou Dongqi, a migrant who was leading a dozen old people to sing. "When I used to live in the village, there weren’t so many entertainment items, but now I can’t pick them, such as singing, calligraphy, table tennis, clapping and dancing, and fan dancing … … Everyone can be happy! " Hou Dongqi said.

  Wang Weixiao, secretary of the Party branch of Nanwenying Community, said that the community party-mass service center can provide 45 government services and convenience services for residents, and through the joint construction of party building, it has built a number of neighborhood-level public service facilities such as community canteens, community museums, neighborhood stations, pension stations, sports activity rooms, and red e-commerce business incubation bases. Together with kindergartens, health service stations, and convenience business points, it has built a number of neighborhood-level public service facilities with perfect service functions, diversified service subjects, higher service quality and higher service efficiency.

  Nanwenying Community Dining Hall officially opened on February 1st this year, adopting the operation mode of "marketization+public welfare", opening to community residents and tourists, and offering exclusive discounts for the elderly: 60.70-year-olds can enjoy a 25% discount, 7180-year-olds can enjoy a 50% discount, and 81-year-olds and above can enjoy a 25% discount. The elderly have completed the real-name authentication and can eat when they brush their faces in the canteen. At present, Nanwenying Community has carried out real-name authentication for more than 1,000 elderly people.

  "In fact, we are still in the exploratory stage of the community canteen project, but we feel very worthwhile to see the happy smiles of the old people when they come to the canteen to eat, and we will continue to make this project bigger and stronger." Chen Churong, deputy stationmaster of the convenience service station of Nanwenying Community Party Group Service Center, said, "We will also provide food delivery services for special elderly groups such as the elderly, living alone and empty nests in conjunction with the community volunteer service team to further meet the personalized, diversified and popular home care service needs of the elderly in the jurisdiction."

  Live a safe life: "one call and one response" to promote the modernization of urban governance

  There are "aborigines" in xiong’an new area who turn farmers into citizens, as well as builders, relocated people and entrepreneurs. The General Secretary of the Supreme Leader clearly pointed out: "We are not building a beautiful new city, but just building a new city for the people to live a better life."

  Governing the city, under the "embroidery" effort. "It is necessary to promptly perceive the worries, worries and worries of community residents and solve them one by one." General Secretary of the Supreme Leader explained the "greatest achievement" of "benefiting the people" in this way.

  "At the beginning of the relocation of the relocated people, the Rongdong area faced problems such as the relocated people not adapting to urban life and the poor coordination and linkage of various construction and operation entities." Yang Shuo, director of the Community Construction Division of Rongdong Management Committee, said that responding to people’s demands in time and solving people’s urgent difficulties and worries have become the top priority of all work.

  To this end, Rongdong Management Committee actively explored a new model of community governance, launched a "one call and one response" working mechanism under the guidance of party building, and relied on "community — Community — The three-level grid of "Loumen", active service and all-round arrangement, forms two accounts and three lists, and builds a grassroots governance system with multi-channel appeal expression, multi-agent participation and multi-department linkage.

  “‘ One-call response ’ The working mechanism was first implemented in Nanwenying Community in Rongdong District, and 292 residents’ needs and demands were coordinated and solved, so that small things did not leave the community and major events did not leave the area. " Wang Weixiao said, "The general party branch of Nanwenying Community consists of 8 temporary grid party branches, 1 temporary community property party branch, 1 temporary community canteen party branch and 25 loumen party groups, forming a party building pattern of linkage from top to bottom and co-construction."

  At the same time, combined with the actual situation, Nanwenying Community, district construction units and resident units jointly carry out activities such as theme education and volunteer service to realize information exchange and resource sharing and jointly solve the needs and demands of the masses.

  In August last year, some people in Nanwenying community reported that the construction of the gas station project on the east side of their residential area caused noise to disturb the people, and there were security risks. Some people also showed excitement during the exchange of WeChat groups. Community cadres immediately contacted the district construction unit to coordinate the construction unit to stop construction at night, and directly contacted the planning department to understand the standardization of gas station site selection, and organized the floor chief and residents’ representatives to hold a residents’ forum and make policy explanations..At this point, the residents untied their hearts and the "contradictions" were successfully resolved.

  Under the guidance of the community, the residents’ sense of ownership in participating in community governance is gradually awakened. At present, Nanwenying Community has set up seven volunteer service teams, including "Firefly" and "Red women soldiers", which have played an active role in policy theory propaganda, human settlement environment improvement, contradiction and dispute mediation, and security risks investigation.

  In 2023, Rongdong District has held several joint meetings on community governance. Up to now, 373 issues such as mass disputes, house maintenance, structural transformation, community environmental sanitation, public facilities maintenance and electric vehicle charging and parking have been solved.

  Have a head start: a stable employment "rice bowl" at home.

  The General Secretary of the Supreme Leader stressed that it is necessary to give priority to employment, improve the guiding policies for employment and entrepreneurship, and strengthen the re-employment training for the labor force in the new district.

  In Nanwenying Community Party and Mass Service Center, there is a "people’s sentiment account". Although the account book is small, it records the major events, minor events and trivial matters of community residents.

  "Hello, do you have any unemployed college students at home who need employment registration service?" At 9 o’clock in the morning, Chen Churong began a day-long home visit to find out the situation of unemployed college graduates in the community and registered them in the "People’s Account".

  "We will regularly check the situation of fresh graduates and unemployed college students in the community. According to the job information provided by Rongdong Employment Service Center, we will accurately push them every two weeks, and everyone will push them at least three times." Chen Churong introduced that in addition to employment assistance for college students, the community has also set up odd jobs stations to summarize the information of nearby enterprises and post them on the bulletin board of the community to provide more intuitive information for community residents to apply for jobs and take part-time jobs.

  "Does our fast food restaurant still recruit people?" "What are the specific requirements for the post?" … … In Nanwenying community odd jobs station, staff often receive consultation calls from the masses.

  Flexible employment is an important channel to increase people’s employment and income. Compared with the traditional fixed working mode, odd jobs are more flexible and independent, and "odd jobs" play an important role in promoting the employment and income of older and difficult people. Since the establishment of odd jobs post, fewer and fewer residents are unemployed at home, and more and more residents are employed at home.

  Jing Dongying, 45, found a job as a "cook" in the canteen through the community. "8 hours a day, walk to and from work for 5 minutes, and pay monthly." Jing Dongying said.

  In order to ensure the high-quality and full employment of the relocated residents, xiong’an new area Rongdong Management Committee has established a "1+N" employment service system, set up Rongdong Employment Service Center and odd jobs post station, built a docking platform between supply and demand, and fully tapped jobs. Through special activities such as large-scale visits and policies to find people to serve at home, we can learn more about the employment status, skills, employment intentions and training needs of each household, record the "public sentiment account" in detail and upload the data to the smart community platform.

  In addition, Nanwenying Community also relies on the red e-commerce business incubation base in Rongdong District to train the relocated people for free. Combine the original local traditional industries such as clothing, plush toys, furniture and bags, develop new formats such as e-commerce sales, and encourage young people in the community to increase their income and get rich through live broadcast. The community red e-commerce business incubator base has carried out 14 training courses such as "network entrepreneurship training course" and "beautician and makeup artist", training 448 students and helping 294 people to find jobs.

  Since the beginning of this year, xiong’an new area has organized more than 80 recruitment activities of various types, providing more than 70,000 jobs for college graduates, migrants and rural laborers.

  Xiong’an new area has entered the stage of paying equal attention to large-scale construction and undertaking Beijing’s non-capital function relief, and the focus of its work has shifted to high-quality construction, high-level management and high-quality relief development.

  The hoof moves forward steadily, and the "city of the future" is growing day by day. Xiong’an new area’s construction is a Millennium project, and it will take a long time to make achievements. We can neither be impetuous nor wait for the important, but we must work hard and diligently. On the new journey, we must strengthen our confidence, maintain our determination, be steady and steady, do good deeds, adhere to a blueprint to the end, and work one after another, truly turn a high-standard urban planning blueprint into a high-quality realistic picture of urban development, and constantly write a new chapter in high-quality development.

Fuel-saving, more comfortable, 100,000 matching 6AT/CVT mainstream family car.

  With the rapid development of technology, in order to achieve better fuel economy and ride comfort, many models on the market are equipped with 8-speed or even 9-speed automatic gearboxes, and even manufacturers are developing 10-speed gearboxes. Of course, these models are expensive. For normal household use, CVT continuously variable transmission and 6AT can achieve both comfort and fuel economy. However, due to cost constraints, automatic transmission models below 100,000 yuan often use mature but relatively outdated 4-speed or 5-speed transmissions, but they are not rare. Here we recommend several models with 6-speed automatic transmission or CVT continuously variable transmission within 100,000 yuan, hoping to help you buy a car.

  

  ● Interpretation of CVT continuously variable gearbox-

  Related technologies: steel belt, chain, hybrid EVT.

  Continuously variable transmission is also called CVT, Audi is named multitronic, Subaru is named Lineartronic, and Nissan is named XTRONIC. The difference with stepped AT transmission is that its speed ratio is not a discontinuous point, such as several gears, but a series of continuous values, thus achieving good economy, power and driving comfort, and reducing emissions and costs. In view of its smooth acceleration characteristics, it is slightly inferior to other gearbox products in terms of pure performance.

  

  Advantages:CVT replaces the transmission gear of the traditional automatic transmission, and is driven by steel belt or chain. In normal automatic transmission, the shift impact and frustration disappear, which is the best among several types of gearboxes in terms of comfort. The gearless CVT gearbox has very linear power output and smooth driving, which can simulate infinite gears to achieve many balances of performance, fuel saving and exhaust emission. In addition, the CVT gearbox is light in weight and small in size.

  Insufficient:The disadvantages of CVT are also obvious. Compared with the traditional automatic transmission gearbox, the manufacturing cost of CVT gearbox is slightly higher, the transmission belt is easily damaged, and it can’t bear large torque. At present, the maximum displacement is limited to 3.5L engine models. In addition, the structural principle is inseparable from mechanical wear, and the service life of steel belt can’t be solved perfectly. Meanwhile, the smooth transmission characteristics also bring slow acceleration response, and the demand for intense driving is not as good as that of other automatic transmission models.

  ● Interpretation of AT automatic gearbox-

  Related technologies: 4AT, 5AT, 6AT, 7AT, 8AT, 9AT.

  AT automatic transmission, that is, using planetary gear mechanism to change speed, can automatically change speed according to the degree of accelerator pedal and the change of vehicle speed. The driver only needs to control the speed by manipulating the accelerator pedal. Hydraulic transmission+mechanical transmission-hydraulic transmission is the hydraulic torque converter, and mechanical transmission is the planetary gear set. This is the most widely used product in automobile transmission at present, from the earliest 4-speed to the highest 9-speed or even 10-speed at present, and the automatic transmission technology is advancing by leaps and bounds.

  

  Advantages:AT doesn’t use clutch to shift gears, and the gear changes little and the connection is stable, so it is easy to operate, which brings convenience to drivers and comfort to passengers.

  Insufficient:First, it is slow to respond to speed changes and is not sensitive to manual transmission, so many car players like to drive manual transmission; Second, the oil consumption is uneconomical, the transmission efficiency is low and the torque range is limited. In recent years, the introduction of electronic control technology has improved this problem; Third, the mechanism is complex and difficult to repair. However, with the development of technology, the gearbox above 6AT can solve a series of problems such as slow response and oil consumption.

  ● Interpretation of dual clutch gearbox-

  Related technologies: dry, wet, 6-speed, 7-speed, 8-speed.

  Powershift is different from ordinary automatic transmission system, which is based on manual transmission and belongs to automatic transmission. Besides the flexibility of manual transmission and the comfort of automatic transmission, it can also provide uninterrupted power output. In layman’s terms, this type of gearbox has two clutches, one for controlling the 1st, 3rd and 5th gears and the other for controlling the 2nd, 4th and 6th gears. When using the first gear, the second gear is ready. Similarly, the shift time is greatly shortened without delay.

  

  Advantages:Compared with the traditional planetary gear automatic transmission, it is more conducive to improving fuel economy and reducing fuel consumption by about 15%; There is almost no torque loss during gear shifting; When the high gear is in the preparation state, the upshift speed is extremely fast, reaching an astonishing 8 milliseconds, almost faster than the best manual gear driver;

  Insufficient:The development cost of double clutch gearbox is high, and the double clutch is precise and complicated, which leads to the high price of the car. The dual clutch gearbox is heavier and bulky than the traditional manual gearbox or even the automatic gearbox. The maximum transmission torque of dual clutch gearbox is low, which limits the modification space of engine; The gearbox lubricating oil needs to be replaced regularly according to the requirements of the manufacturer, and the replacement cost is not cheap; The failure rate is still slightly higher than the traditional mature gearbox system.

  ● BYD’s new F3 energy-saving version

  Gearbox: 6-speed dual clutch independently developed.

  Automatic transmission price: 65,900-72,900 (Huimin subsidies 3,000 yuan)

  BYD’s brand-new F3 "energy-saving version" model has been officially listed in China recently, with a price range of 51,900-72,900 yuan, and all departments enjoy an energy-saving subsidy of 3,000 yuan. The new car has been adjusted in appearance, power and configuration, which is expected to further strengthen the advantages of BYD F3 products, and at the same time, it is expected to become the lowest-priced model equipped with 6AT gearbox.

  ● Wheel hub style changes, increasing NVH improvement.

  

  

  

  The new F3 energy-saving version adopts a new wheel hub shape, adding another trendy element to the appearance; At the same time, NVH improvement, overall noise reduction and paint improvement have greatly improved the quality of the whole vehicle, and consumers will get a more comfortable driving experience.

  ● A variety of interior color matching styles, and the overall configuration has been improved.

  

  

  

  

  On the basis of the original color matching design, brown interior and dark interior are added to provide consumers with more choices. The high-profile models have dual navigation systems such as car TV, car Bluetooth, Beidou and GPS, and are equipped with the same level of seconds kill. In addition, automatic transmission models are also equipped with ESP whole vehicle stability system to improve driving safety.

  ● High ride comfort, space to continue cash.

  

  

  Although the wheelbase is still 2600mm, which is the same as that of the previous generation, it basically meets the daily requirements in terms of seating space, and the overall performance is that it belongs to the mid-range level in compact cars, and it is no problem to meet the needs of ordinary households.

  ● Sufficient power performance and brand-new 6-speed automatic gearbox.

  

  This model is equipped with a 1.5L naturally aspirated engine, with a maximum power of 80kW(109PS) and a maximum torque of 145Nm. The transmission system provides two options: 5-speed manual or 6-speed automatic. It is worth mentioning that the BYD DCT gearbox has adopted a new set-up, which has significantly improved fuel economy and smoothness.

  

  Summary:The features of the new BYD F3 energy-saving version are very prominent, and its extremely rich configuration is its killer. The new model has further improved the configuration. After the subsidy for Huimin, you can enjoy many leapfrog configurations for less than 70,000 yuan, which is believed to have great temptation for most consumers. Not only that, the latest 6-speed dual-clutch gearbox model is in the leading position in terms of technology and comfort.

  ● Changan Suzuki Qiyue

  Gearbox: Aisin 6-speed automatic manual integration

  Automatic transmission price: 99,900-121,900 (Huimin subsidies 3,000 yuan)

  Changan Suzuki Qiyue, which has just been listed for less than a short time, is a junior in the compact car market. Obviously, its struggle road is not so easy, but it has the cost-effective advantage of a joint venture 6AT automatic transmission model of less than 100,000 yuan. Many unique features are also one of its competitiveness, no matter from the body design or driving experience.

  ● Appearance continues. Concept car design is streamlined and dynamic.

  

  

  

  

  For friends who often pay attention to Suzuki models, Suzuki Qiyue is not unfamiliar with this new car. As early as the Beijing Auto Show in April this year, Suzuki released the prototype of this car-the –ALIVIO concept car. The production version of Suzuki Kaiyue we see today almost completely continues the design language of ALIVIO concept car, and at the same time, some adjustments have been made in details, especially the tail feels like a small steel gun.

  ● Numerous leapfrog comfort configurations

  

  

  

  

  The interior design is practical at home, and the shape of the center console is basically symmetrical. The color scheme with deep top and shallow bottom is also the most comfortable and practical color scheme. The configuration of the air outlet of the rear air conditioner was unexpected. You know, there are very few models with this configuration in this class. It seems that paying attention to the comfort of rear passengers has spread to the compact car market. At the same time, the high-profile models also have the steering wheel shift function, which is extremely rare in 100,000 models.

  ● The spatial performance is remarkable.

  

  

  Although the axle is only 2650mm, the space performance of Kaiyue is remarkable, and the experiencer with a height of 180cm has enough comfortable space, which is no less than the effect of some sports medium-sized cars, especially the rear leg is very large.

  ● The powertrain has excellent fuel economy, and Aisin 6AT is mature.

  

  In terms of power, Kaiyue is equipped with G-INNOTEC 1.6L all-aluminum VVT naturally aspirated engine and 6-speed automatic manual transmission from Aisin Japan. In today’s compact car market where supercharged engines are rampant, such power matching is slightly conservative. However, the official fuel consumption of 100 kilometers comprehensive working condition is only 5.3L, so it can be said that this is a mature and economical power choice in power matching.

  

  Summary:Kaiyue’s biggest killer is its superior rear-row experience and incomparably fuel-efficient powertrain. Apart from the engine, the 6AT gearbox is indispensable. In addition, the sun shade, legroom, and rear air outlet, which can be called leapfrog configurations, all appeared on this compact model. Changan Suzuki Qiyue’s design direction is very targeted to Chinese people. Obviously, it has done in-depth research in China at the beginning of the design, and the "non-mainstream" price is definitely the most urgent demand of prospective car owners.

  ● Hippocampal Familia M5

  Gearbox: modern 6-speed automatic manual integration

  Automatic transmission price: 88,900-118,900

  In 2002, the first generation of Familia Haima came out. In the past 12 years, three generations of products have achieved more than one million sales, which proved their own value. As the fist product of Haima Automobile, Familia gradually faded into people’s field of vision in the automobile tide. In order to enhance the brand competitiveness, a new generation of Familia Haima came into being in 2014, which was jointly built by many top international teams. The fashionable and dynamic shape changed from the calm style in the past, and the gearbox will use 6MT and 6AT, with leading technical content.

  The front face looks like the Buick family, and the overall design is fashionable and dynamic.

  

  

  

  At first glance, I saw a new generation of hippocampus Familia M5, which was very young in appearance and more catered to the aesthetics of young people. However, deja vu faces still make Buick Regal emerge in our minds for the first time. In particular, the shape of the net and the straight waterfall air intake grille are carved in the same mold, and the slender headlights and the sporty front bumper are full of charm, and the international fashion sense arises spontaneously.

  ● InteriorFashion design conforms to young people’s aesthetics.

  

  

  

  

  

  The new generation Familia M5 interior is also dynamic and fashionable, with exquisite materials and solid workmanship. As a whole, it adopts two color schemes of black orange and black rice, with black orange matching fully showing the sports style and black beige matching to create a warm home style. The center console is biased towards the driver’s side, with simple and generous design, clear operation interface and clear functional area; The fly in the ointment is that most of the central control materials are hard and plastic, which does not show a sense of grade, but the integration of carbon fiber elements is one of the highlights. In terms of function, compared with the old model, Bosch’s ninth generation ESP stabilization system is added, and the response speed is faster and safer.

  ● Satisfactory spatial performance.

  

The wheelbase of 2685mm is the leading level in the same class. Of course, for those super A+ compact cars with a wheelbase of more than 2700mm, there is still a long way to go, but it still creates ample rear legroom. At the same time, for the experiencers with a height of 180cm, both the front and rear head space are basically satisfied. It is commendable that the seat comfort is excellent in the same class, and both the wrapping and the support are satisfactory.

  ● Advanced engine technology and mature performance of modern 6AT.

The 1.6-liter naturally aspirated engine of Familia M5, a new generation, is the second generation product independently developed by Haima. Four technologies, such as plastic variable length intake manifold (VIS), aluminum alloy cylinder block and cylinder head, 4-1 tightly coupled exhaust manifold, and engine lightweight, are applied, and the engine performance is further improved, with better fuel economy, energy saving and environmental protection. At the same time, the combination of 6MT and 6AT gearboxes can be regarded as a higher level in the same level, and the actual use of 6MT gearboxes is clear, while 6AT gearboxes come from modern 6F24 models in Korea, so there is no doubt about the reliability maturity. The new generation Familia M5 inherits and promotes the Familia brand champion chassis gene, and the chassis is solid and steady.

  

  Summary:Familia M5 inherited the control advantages of the old Familia, and the upgrade of internal and external styling brought a sense of fashion and grade, making it easier to attract face-oriented consumers. However, in the market surrounded by many competitors, the power of 1.6L is a bit stretched, but the modern 6AT gearbox is still in the advanced ranks among competing models at the same level, not inferior to Aisin products.

  ● Dongfeng is popular-Jingyi S50

  Gearbox: CVT continuously variable in Bang Qi, Belgium.

  Automatic transmission price: 79,900-102,900

  Dongfeng Fengxing is the manufacturer of MPV in the impression. Although SUV models were involved later, Lingzhi, the MPV model it produced, is still an important part of the whole Dongfeng Fengxing. Last year, Dongfeng Fengxing launched the first family car Jingyi S50, and the listing of this family car also means that Dongfeng Fengxing has taken an extremely important step in the field of passenger cars.

  A design that satisfies the aesthetics of most consumers.

  

  

  

  Jingyi S500 has its own high recognition in design. The appearance created by the independent design team tends to be young and energetic, but the appearance that does not excessively pursue individuality conforms to the tastes of most consumers, and also conforms to the original intention of Dongfeng to create for young people.

  ● ESP is standard in the whole system, which is rare at the same level.

  

  

  

  

  

  The traditional T-shaped layout in Jingyi S50 interior is simple but very regular. It is worth mentioning that Jingyi S50 adopts all-black interior, supplemented by silver decorative strips, which makes the interior look equally dynamic and echoes the exterior design well. In terms of configuration, the ESP body stability control system from Bosch is the standard configuration of Jingyi S500. In addition, the top model is also equipped with side airbags and front and rear head air curtains. In terms of safety configuration, Jingyi S500 does have certain advantages compared with the same price model.

  ● Space performance is almost perfect at the same level.

  

  

The wheelbase of 2700mm is leapfrog, which brings a large space in the back row. For those who are 178cm tall, they can easily tilt their legs on the premise of keeping the front row unchanged, and the head space in the front and rear rows is also very plentiful.

  ● The engine comes from Mitsubishi technology. The CVT gearbox comes from Bang Qi.

  

  In terms of power, Jingyi S500 has two different displacement engines, 1.5L and 1.6L, which are different according to the different gearboxes of the engines. The 1.6L model is equipped with a 4A92 engine from Mitsubishi, with a maximum power of 90Kw and a maximum torque of 151 N m. It is matched with a 6-speed CVT gearbox that can be manually simulated, while the 1.5L model is matched with a 5-speed manual gearbox provided by GETRAG, Germany, and the 1.6L engine is matched with a CVT gearbox provided by Bang Qi, Belgium.

  

  Summary:As the first family car of Dongfeng, it can be seen that the manufacturer is still more careful. Although the appearance and interior have not been designed too much, the doctrine of the mean is indeed a relatively safe choice for a model used to open up the market. The performance in space is particularly outstanding. Both manual and automatic gearboxes are from famous houses, and the price of less than 100,000 yuan can also be a great help for Jingyi S50.

  ● FAW-Volkswagen New Jetta

  Gearbox: Aisin OEM 6AT automatic manual integration

  Automatic transmission price: 98,300-119,300.

  It doesn’t seem to be an exaggeration to say that Jetta is an "old friend" of China people. It has been nearly 24 years since the first Jetta was officially rolled off the assembly line in Changchun in December 1991, and there is no doubt about the reputation of the old Jetta. Now, the new Jetta has been on the market for some time. Judging from the current market feedback, it has not eclipsed the past aura. On the contrary, it still relies on the Volkswagen gold-lettered signboard and the powertrain that does not lose the same level.

  ● More popular design.

  

  

  The new Jetta is no longer a square-headed, square-brained model, completely getting rid of the shackles of the traditional impression in the past, but one thing remains unchanged: simplicity and mediocrity are still the main theme of the whole car. Compared with the old Jetta (4415×1674×1415mm, with a wheelbase of 2471mm), the new Jetta has a size of 4487/1706/1470 mm and a wheelbase of 2603.

  ● Interior design conforms to Volkswagen standard style.

  

  

  

  

  The classic of the public is that you won’t do too many articles on the surface. Only you have a deep experience can you taste the subtlety of the design, and the interior design is absolutely standard and popular. Limited by the cost, the new Jetta doesn’t have many comfortable functions, but it is completely sufficient for daily use, selling gold-lettered signboards.

  ● Space performance is enough for home use.

  

  

The exterior size of the new Jetta is not outstanding, but the internal space is not thin at all. The model with a height of 1.8 meters and a strong body sits in the car, and space is not a problem at all. Of course, if there are three male adults in the back row, the lateral width will be relatively crowded, especially in winter when wearing heavy clothes.

  ● Volkswagen E211 engine matches 6AT gearbox.

  

  The new Jetta is equipped with a brand-new EA211 series engine, with two displacements of 1.4L and 1.6L. Among them, the 1.6L automatic luxury type has a maximum power of 81kW/6000rpm and a maximum torque of 160Nm/3800rpm, matching the brand-new 6-speed automatic transmission, which is manufactured by Aisin Company of Japan and has excellent maturity and stability.

  

  Summary:Compared with the current competitors, the new Jetta is better than the competitors in driving comfort and driving convenience. Although the power parameters are not as good as those of some models with T, the overall matching will give you a more ideal driving experience, among which EA211 engine and 6AT gearbox are indispensable. In some details, the new Jetta will think more and give you more practical configurations, rather than a display, a very complicated operation and unreasonable control. In terms of price, including several thousand yuan discount, if there are not too many requirements for configuration, the automatic transmission can be done within 100,000 yuan.

  ● Dongfeng Nissan New Sunshine

  Gearbox: Nissan CVT continuously variable speed.

  Automatic transmission price: 89,800-112,800.

  When it comes to Nissan, I believe everyone’s first reaction will be to save fuel, have a large space and have excellent comfort. Adhering to these advantages, in February this year, Sunshine ushered in a small change, closer to the family-style front face changes, and the introduction of navigation system in high-profile models, which once again enhanced its freshness and practicality, while continuing to use the continuously variable powertrain.

  ● The new appearance is slightly changed, which is more in line with the family design.

  

  

  The appearance of the new sunshine has not changed drastically, but the details have been optimized to some extent. The enlarged X-shaped front air intake grille is more atmospheric, and the headlights with more sharp edges and corners make it more in line with the family concept. In addition, the chrome-plated decorative strip added on the periphery of the circular fog lamp area makes the whole front face more textured than the old one.

  ● Interior design conforms to Volkswagen standard style.

  

  

  

  

  Compared with the appearance, the new sunshine has changed more in the interior. Compared with the more moderate interior design of the old model, this change looks much more fashionable, and the design style of the three-position steering wheel is more suitable for the family style. At the same time, the new Sunshine will upgrade the DA navigation for car owners free of charge (except for the top and lowest equipment). The increase of this touch-screen multimedia system makes the new Sunshine keep pace with the times compared with the old one because the old one is not equipped.

  ● Excellent spatial performance as always.

  

  

Generally speaking, the sunshine space can still be ranked in the middle and upper reaches of compact cars with the same price. Although the shape data is not outstanding, the passenger compartment has been taken care of the most and the layout is reasonable. In addition, the comfort of the seat is also very good, which inherits the glorious tradition of Nissan and is worthy of recognition.

  ● Nissan’s most fuel-efficient powertrain: 1.5L+CVT.

  

  In terms of power, New Sunshine is still equipped with the same 1.5L four-cylinder naturally aspirated engine as the old one, with a maximum power of 112 HP (82 kW) /5600rpm and a maximum torque of 139 Nm /4000rpm. There is no change in the gearbox, and Nissan’s CVT continuously variable gearbox is still used, which has outstanding fuel-saving and smooth effect.

  

  Summary:The main change of the new sunshine lies in the appearance. A lot of chrome-plated decoration and the latest family design make the whole car look more atmospheric and should attract more home users. In terms of space and driving, it inherits all the advantages of the old model, which is energy-saving, easy to drive, smooth and comfortable, and its performance fully conforms to its positioning. Of course, it is inseparable from that advanced CVT gearbox.

  【 Conclusion 】Looking back on the past, it is quite gratifying to have a 5-speed automatic gearbox model in the choice of a 100,000-yuan family car. Most of them are 4AT gearbox models, which are not ideal in terms of fuel-saving effect or driving comfort. Therefore, most consumers prefer to choose manual models. With the continuous innovation of technology, 6AT and CVT gearboxes have become the mainstream, and both comfort and fuel-saving have just met the consumption crowd of 100,000 car buyers. Among them, many products come from many big-name manufacturers, such as Aisin, Bang Qi, Nissan, etc. There is no doubt about maturity and reliability. Even the 6-speed dual clutch independently developed by BYD is eye-catching and has better performance. Of course, how to choose between 6AT and CVT? I believe that fuel economy is the first, and good driving is the second. We will see after the test drive!

(Report)

Meituan buys medicine: After New Year’s Day, the demand for A and B drugs will rise, and Beijing, Shanghai, Guangzhou and Shenzhen can already "check at home".

On January 4, the National Influenza Center released the 52nd week of "Influenza Surveillance Weekly Report". The monitoring data showed that the positive rate of influenza virus testing in southern provinces increased this week, while that in northern provinces decreased. The A (H3N2) subtype (that is, influenza A) is the main type, and the proportion of B (Victoria) series (that is, B) continues to increase. During the same period, the Meituan Drug Buying Health Index on January 5 shows that the national A and B stream-related drugs oseltamivir and Sufuda have fallen behind after a short period of demand last week, and the search and order volume of drugs have shown an upward trend this week. At present, Meituan Pharmaceutical has opened a home express inspection service in Beijing, Shanghai, Guangzhou and Shenzhen. Doctors remind a variety of influenza and respiratory diseases during the epidemic period, and it is meaningful to identify the

According to CCTV news client side news, Shanghai Children’s Hospital’s recent outpatient and emergency patient test results show that the total number of influenza patients has not changed in recent times, but the proportion of outpatient and emergency influenza patients has risen from less than 10% in early December to more than 40% in recent days. But overall, there are still more A-stream patients than B-stream patients. Meituan’s health index shows that in addition to the growth of A-stream and B-stream drugs, the search for cough medicine dextromethorphan nationwide has nearly doubled this week. Nasal congestion, runny nose, cough, sore throat, and fever have become high-frequency terms for recent inquiries.

Figure: In the past week, right methorphan has nearly doubled, and nasal congestion, runny nose, cough, sore throat, and fever have become high-frequency words for recent inquiries (Source: Meituan Drug Buying Health Index)

From a city-by-city perspective, the order volume of oseltamivir Shenzhen has nearly doubled in the week; the order volume of Sufuda in Changzhou, Taiyuan, Fuzhou, Dalian and Shantou has more than doubled in the week; the order volume of dextromethorphan in Xuzhou, Taiyuan and Huizhou has more than doubled in the week. Overall, the jump rate in East China and South China is more obvious, and everyone still needs to pay attention to protection.

After the recent B-stream related news frequently appeared on the hot search, many netizens also said: "I thought that the A-stream was about to be sent away, but I didn’t expect the B-stream to come again. After I have symptoms, I don’t know what virus I have been recruited?" In this regard, the person in charge of the Meituan Pharmaceutical Pharmacy Service Center introduced: "Among the several epidemic diseases that have received high attention recently, the A and B stream has the characteristics of urgent onset, hot topic, headache, and muscle soreness all over the body. The body temperature often peaks within a few hours or 24 hours, reaching 39-40 ° C, or even higher; COVID-19 patients usually have fever, cough, shortness of breath, fatigue, headache, sore throat, and myalgia symptoms, and a small number of patients will have abnormal sense of smell and/or taste; while the common cold is mostly caused by viruses, a small part is caused by bacteria, and local symptoms are the main ones, including sneezing, runny nose, nasal congestion, sore throat, cough, etc. Generally, there are few fever symptoms, or only low fever. If you can’t tell the difference, you can test the results first and then treat it symptomatically. "

Ms. Fei, who lives in Beijing, has been sneezing frequently recently, has a runny nose, coughs, has a dry and itchy throat, and her whole body is sore. Because she doesn’t know what type of disease she is suffering from, she first ordered the "home express inspection" service on Meituan to buy medicine. She received the test report in about three hours and found that she was not infected with A and B. Then, Ms. Fei asked the doctor at the entrance of Meituan to ask the respiratory physician of Tier 1 hospital how to take medicine. The respiratory doctor who received the treatment asked Dr. Liu in detail about Ms. Fei’s specific symptoms and medication. According to the test results and the patient’s symptoms, it is more likely to consider ordinary influenza. Therefore, she prescribed relevant medicines for Ms. Fei and provided detailed medication instructions and health suggestions.

The relevant person in charge of Meituan Pharmaceutical Pharmacy Service Center specially reminded that antiviral drugs should be taken symptomatically according to the doctor’s instructions. You should not reduce the dosage or blindly stop the drug after the symptoms are relieved. You need to take it in sufficient quantities and for a full course of treatment under the guidance of a doctor. Similar antipyretics cannot be taken together. For example, ibuprofen and acetaminophen are both non-steroidal antipyretic and analgesic drugs. Avoid combining them to avoid overdose or toxic synergy. Do not take cold medicines containing the same ingredients repeatedly. Most compound cold medicines contain acetaminophen to avoid liver damage caused by overdose of acetaminophen. During the medication period, you should avoid smoking, alcohol and spicy, cold and greasy foods. It is not advisable to take tonic traditional Chinese medicine at the same time during the medication.

At the same time, the New Year’s Day holiday has ended, and the person in charge of Meituan Pharmacy Service Center also reminded that after the holiday, you should pay attention to the adjustment of work and rest, especially after returning from foreign travel, you should keep warm or take off clothes according to the specific situation. In addition, daily preventive measures are essential to block the spread of B stream. It is recommended that you pay more attention to your own situation and maintain good hygiene habits.

The innovative development of the digital economy will promote the green transformation of the industrial structure

  The government work report of this year’s "two sessions" proposed that "vigorously promote the construction of a modern industrial system and accelerate the development of new quality productive forces" as the first task in 2024. New quality productive forces are advanced productive forces generated by revolutionary breakthroughs in technology, innovative allocation of production factors, and deep industrial transformation and upgrading. Further promoteInnovative development and the promotion of high-end, intelligent and green transformation of traditional industries are important measures to accelerate the development of new productive forces.

  The previous report of the 20th National Congress of the Communist Party of China pointed out that it is necessary to "promote deep integration with the real economy and build a digital industrial cluster with international competitiveness."

Data elements are deeply empowered, which can help enterprises capture these market opportunities, develop products and services that meet green requirements, and promote the development of industrial structure in the direction of green transformation.

  Digital factors promote industrygreentransformationreturnexistWhat bottlenecks?

  The current digital economy-related industries are in the early stages of development, and there are some shortcomings in promoting the green transformation of the industrial structure.

  First, the energy consumption of industries related to the digital economy is relatively high. The rapid development of the digital economy has brought about the demand for large-scale data storage, processing and transmission, which requires a huge energy supply to support.Is supportThe critical infrastructure for big data processing and online services usually requires a large number of servers and network equipment, while big data processing requires large-scale computing resources and storage devices. These devices generate a lot of heat during operation and require cooling systems to maintain a stable working temperature. Cooling systems usually consume a lot of energy, resulting in increased energy consumption. Moreover, the development of the digital economy requires a large amount of data transmission and communication. The Internet, mobile communication and data transmission networks all need to consume a lot of electricity to maintain their operation and coverage. With the growth of the digital economy, the energy consumption of network transmission and communication has also increased accordingly.

  Second, the cost of digital transformation in traditional industries is high. First, the digital transformation of enterprises requires updating the existing technology infrastructure, introducing new software and hardware systems, and training employees to adapt to new workflows, resulting in higher technology update and training costs. Second, digital transformation may require closer collaboration and information sharing with suppliers, partners, and customers, which in turn incurs supply chain adjustment and integration costs. Finally, the digital transformation of enterprises also needs to ensure thatEnsuring the security and privacy of data may require additional investments, such as establishing secure data storage facilities, adopting encryption technology and implementing strict access control measures

  Third, the scope of digital economy empowerment is still insufficient. Traditional industries usually have complex business processes and traditional information systems. Introducing digital technology into these systems may require large-scale technical and system integration work. This may involve issues such as compatibility with existing systems, data migration, security, etc., resulting in slow digital transformation. In addition, the construction and penetration of digital infrastructure in some less developed regions is relatively low, and the popularization of digital skills and knowledge is relatively low. Therefore, these regions may face certain difficulties in carrying out green transformation and digital development.

  Policy recommendations to deeply empower data elements

  The first is to optimize the layout, improve equipment and systems and other measures to improve energy efficiency and promote the green development of the digital economy industry. Optimizing the layout can not only reduce cooling demand and reduce energy consumption, but also promote the effective use of renewable energy. For example, building data centers in the western region rich in air-conditioning resources, using natural airflow for alternative cooling. Moreover, the western region also has better wind and light resources. Through the matching update with the power sector, it can greatly realize the dependence on traditional energy and reduce carbon emissions. In addition, governments and regulators can strengthen environmental supervision of the digital economy industry and develop corresponding policies and standards to promote the use of more energy-efficient servers, optimized equipment configuration, and improved cooling system efficiency in data centers, providers, and operators, among others, in order to promote the development of a green and sustainable digital economy.

  Second, strengthen data infrastructure building and technology popularization, strengthen data privacy and security protection, and improve the enthusiasm of enterprises for digital transformation. The government can increase investment in data infrastructure in underdeveloped areas, including high-speed Internet, data centers, cloud computing platforms, etc. At the same time, strengthen data science,Talent training and skill upgrading in areas such as big data analytics can provide basic support for local enterprises to deeply empower data elements. In addition, clear and stable policies can provide a favorable environment for deeply empowering data elements, and the construction of laws and regulations on data privacy and security should be strengthened. Strengthening technologies and measures to ensure that user data is properly protected, and establishing regulatory mechanisms to supervise the compliance of data processing and use can enhance the good expectations of enterprises and the public for data elements empowering, and promote the further development of the digital economy, thereby providing stronger momentum for the development of new quality productivity.

  Third, promote data sharing and openness, promote data exchange and cooperation between different departments, institutions and enterprises, and remove "stumbling blocks" to development. The government can encourage enterprises and research institutions to conduct innovative research and development in terms of deeply empowering data elements by providing incentives such as funding and tax incentives. The government can also establish innovation support platforms and incubators to provide technical support and market orientation to help innovative projects land and grow. At the same time, by establishing data sharing platforms and formulating data open standards and policies, it can facilitate data sharing and openness among various departments and organizations, thereby encouraging the wide use and innovation of data elements, and opening up data channels for the green transformation of industrial structure and the development of new quality productivity.
