Science and Technology Daily, Beijing, October 17 (Reporter Gu Gang) Many mammals spend the cold season by hibernating. The lower the body temperature of hibernating animals, the more energy consumption can be reduced. But this is not all good. A recent study by the Veterinary University in Vienna, Austria, found that lower temperature tends to increase telomere contraction, which may accelerate cell death. To avoid this result, animals need to consume a lot of energy to repair cells.

　　Researchers have found that during hibernation, mammals with lower body temperature can reduce their physical exertion by more than 90%. In the absence of food, reducing energy consumption is very beneficial to the survival of animals. However, animal hibernation at low temperature can cause problems such as telomere contraction. In the experiment of forest Dormouse and garden Dormouse, it was found that Dormouse wintering at higher body temperature has longer telomeres, but it also consumes more energy. Researcher Julia Novak explained: "This seems to be a compromise between maintaining complete telomeres and cell survival, and minimizing energy consumption by hibernating at low body temperature."

　　The researchers also found that there are significant differences in telomere shortening between forest Dormouse and garden Dormouse when they hibernate at different temperatures. They were put into hibernation at 3℃ and 14℃ respectively in the laboratory. Dormouse consumes more energy at 14℃ than at 3℃, while chromosome telomeres are much better at 14℃. This new understanding supports the widely accepted hypothesis that hibernation also has a price.

　　Novak believes: "Deep hibernation is related to the cost at the cellular level, that is to say, the recovery of telomere length after shortening must be at the expense of animal physical consumption. Previous scientific assumptions may overestimate the benefits of deep hibernation in animals that can reduce physical exertion. "

　　Although hibernation has many advantages, the research also found that it has related problems. Due to the decline of immune function, slow response and increased oxidative stress, frequent awakening of animals from hibernation will also lead to a rapid reduction of energy reserves, and the up-regulation of metabolism is related to the production of reactive oxygen compounds, which will lead to a faster shortening of telomeres.

　　The length of telomeres is usually used as a sign of aging, which shortens after each somatic cell division. If its length cannot be recovered, the cell will eventually die. During hibernation, telomere recovery is destroyed.

　　This study is also of great significance to human medicine. Studies have shown that chronic human stress will accelerate telomere shortening. On the contrary, lifestyle changes will slow down telomere shortening, which will have a positive impact on the aging process of cells and the whole organism.

In today’s automobile market, the rise of new energy vehicles has become a major trend in the industry. As a new force in China’s new energy automobile market, Xingtu Automobile has launched its first brand-new medium and large SUV-Xingtu Xingjiyuan ET. On May 9, the car was officially launched. This time, eight models were launched, with the price range of 189,800 yuan to 319,800 yuan, and there were multiple car purchase benefits.

The length, width and height of Xingjiyuan ET are 4955/1975/1698mm and the wheelbase is 3000mm, respectively, and it is positioned as a medium and large SUV. In appearance, Star Road Star Era ET continues the consistent design concept of "Great Beauty and Minimalism" of Star Road Automobile, and adopts a closed front face design with through daytime running lights and LED headlights, which adds a sense of avant-garde to the vehicle. In addition, the body design is tough and powerful, equipped with 19/21 inch optional wheels, which enhances the fashionable and dynamic atmosphere. The luxurious texture of the tail design, the sporty semi-enclosed rear window spoiler shape, and the blackened through taillight group further enhance the layering and sporty atmosphere of the vehicle. On the whole, Star Road Star Era ET pays attention to the polishing of details in the design, showing the fashion and dynamics of new energy vehicles.

In terms of interior, Star Road Star Era ET adopts a modern and simple style, equipped with a 10.25-inch full LCD dashboard and a 15.6-inch central control car screen, which integrates the Star Road OS in-vehicle intelligent system. In terms of configuration, it also provides a number of configurations such as oversized canopy, leather steering wheel heating, mobile phone Bluetooth key, electric tailgate position memory, etc., which improves the driving experience. The overall design is simple and atmospheric, and the functional configuration is rich and practical, which meets the expectations of consumers for the interior of medium and large SUVs.

Star Road Star Era ET provides two power systems: extended range version and pure electric version. Among them, the pure electric version provides two modes: rear-drive single motor and four-wheel drive dual motor. The whole region adopts 800V high-voltage architecture. The rear-drive version adopts the maximum power of 230kW and the maximum torque of 425Nm. The Ultra version has a comprehensive power of 413kW and the maximum torque of 691Nm. The time from 0 to 100 km/h is only 3.8s s. Contemporary Amperex Technology Co., Limited Shenxing super-charged battery pack with two capacities of 77kWh and 100kWh is provided. The maximum cruising range of CLTC is 760km, and it can last 400km after charging for 10 minutes.

The extended range version is equipped with a 1.5T range extender and a rear-drive single motor. The maximum power of the single motor is 195kW, the maximum torque is 324Nm, the CLTC pure electric cruising range is 200km, and the CLTC comprehensive cruising range can reach 1518km. I have to mention that in a recent extreme endurance test, the extended-range version of Star Era ET ran 2,141.4 kilometers with full fuel and electricity! In terms of power output and endurance performance, the competitiveness of Star Road Star Era ET is not strong, and it is a proper strength player.

In the medium and large SUV market, the Star Road Star Era ET will face fierce competition, especially the L7/L8 of LI and the M7 of Wenjie Automobile, which continue to be popular in the medium and large SUV market. No matter the sales volume, quality or word of mouth, these models can bring full pressure to Star Era ET, so it is more difficult to stand out in the price range of 200,000-400,000 yuan.

The official listing of Star Road Star Era ET indicates that the development of new energy vehicle market in China has entered a new stage. As a brand-new medium and large SUV model, Star Road Star Era ET has shown outstanding competitiveness in appearance design, interior configuration and power system. However, in the highly competitive market environment, Xingtu Automobile still needs continuous efforts to enhance brand awareness and market reputation in order to win the favor of consumers. It is believed that with the passage of time, Star Road Star Era ET will open a new chapter in the China automobile market and lead the new trend of medium and large SUVs.

The fiery market of new energy vehicles is attracting more and more enterprises to enter the market, and Haier, the home appliance giant, is no exception.

Enterprise investigation shows that not long ago, Haier established a Katechi Automobile Technology Development Co., Ltd. in Qingdao. Its legal representative is Ren Xian Cun, with a registered capital of 150 million yuan, and its business scope includes research and development of emerging energy technologies; Automobile sales; New energy vehicle sales; Retail of auto parts, etc.

Searching for the relevant terms of "Qingdao Katechi" in the enterprise search will also lead to "Qingdao Katechi Zhixing Automobile Technology Co., Ltd." and "Qingdao Katechi Innovation Technology Co., Ltd.". These car-related companies, without exception, have the participation of Haier.

In August this year, some media reported that "Haier is planning to build a car, enter the field of complete vehicles and launch its own brand of automobile products".

After just over three months, Haier set up a new company in full swing, which inevitably caused public suspicion. However, on November 28th, Haier officially denied these so-called rumors, and explained that relying on its kaos industrial Internet platform, the company is currently building an industrial Internet sub-platform in the automotive field with relevant automobile companies, aiming at empowering enterprises in the automotive industry chain to digitally transform.

In other words, Haier is more willing to cooperate with car companies and adopt the OEM model.

Haier curve car making

As we all know, building a car is a "burning money" project, and the return period is long. At the same time, Haier is not the only enterprise that makes cars across the border, and there are not many real successes. Even if the new car is mass-produced, it will face the market’s doubts.

Haier knows this well, so it chose the "lightweight" way to enter the automobile industry. Not only do you not need to invest too much in the early stage, but you can also make money more easily by taking advantage of the technical advantages of the whole car companies without establishing a production line.

However, Haier has obviously changed its strategy for entering the automobile industry. In the early days, Haier, as a "small white", focused more on investing in parts suppliers and car networking car service providers. These include Feichi Magnesium, Botai Internet of Vehicles, and Tongming Hi-Tech, an auto parts manufacturer.

Later, with accumulated experience, it began to formally enter the vehicle manufacturing industry. In March last year, Haier and SAIC signed a strategic cooperation, and the two sides will cooperate deeply in the fields of intelligent manufacturing transformation, smart car research and development and application, car home interconnection, new energy and intelligent vehicle application promotion.

On April 10th, Haier Group reached a cooperation with Chery, and reached the cooperation intention in the fields of automobile industry Internet platform and factory construction, smart industrial park supply chain and procurement digitalization.

In June, Haier signed a cooperation agreement with Geely again. According to the agreement, the two parties will cooperate in the Internet of Vehicles and smart home interconnection, marketing channels and marketing innovation models, finance and Internet of Things payment.

In the industry’s view, Haier did not directly build a car, but entered the automobile ecological chain. Through its industrial internet platform, it can connect automobile manufacturing-related enterprises and intelligently connect two life application scenarios, namely car and home, thus realizing the Internet of Everything, which is somewhat similar to Huawei now.

Market potential is the key?

From a macro point of view, Haier’s choice of "cross-border" is also somewhat helpless. On the one hand, the depression of the home appliance industry has put pressure on the entire home appliance industry. According to the semi-annual report on all categories of household appliances in 2022 released by AVC, the retail sales of household appliances in China reached 338.9 billion yuan in the first half of this year, down 9.3 percentage points year-on-year.

On the other hand, the rapid warming of the new energy vehicle market is in sharp contrast with the home furnishing industry. According to the latest data of China Automobile Association, in October this year, the monthly sales volume of new energy vehicles was 714,000, an increase of 81.7% year-on-year, with a market share of 28.5%. From January to October, the cumulative sales volume of new energy vehicles was 5.28 million, a year-on-year increase of 1.1 times, and the market share reached 24%.

At the same time, for the future development scale prospects of the two industries, there is also a significant difference in data. According to NTCysd data, in 2021, the market size of the global home appliance industry will be about 1,351.9 billion yuan, and it is expected to reach 1,834 billion yuan in 2028. The industry estimates that the value created by the global automobile market every year is nearly 10 trillion US dollars, which is more than five times that of the home appliance industry.

Therefore, home appliance enterprises that tend to be "saturated" urgently need new profit growth points, and new energy vehicles just give an opportunity.

In addition, unlike fuel vehicles, smart cars have been integrated into the entire ecology of users, achieving a seamless connection between cars, homes and offices. As the second half to measure the success of the transformation, Haier has a natural genetic advantage.

As an important part of smart cars, Haier not only owns the world’s first scene ecological brand "Three-winged Bird", but also owns the platform of Haier Zhijia-Zhijia App. The number of daily users of this platform has reached tens of millions, and it is still growing. At the same time, Haier’s 300 experience stores are quite attractive to any car brand. This is why Geely’s Krypton brand was selected for display in Haier’s store immediately after the launch of "001".

It is worth mentioning that before Haier entered the automotive field, it was nothing new for home appliance companies to build cars. Midea, Hisense, Gree, Skyworth and other home appliance companies have already laid out the automobile industry. Just last month, Gree just got Tesla’s "chassis" order.

Therefore, for Haier, "building a car" is not an easy task, and the competitive pressure is still great.

May Day "I really want to see you" concert. Figure /IC

More than ten days after the Mayday concert, a huge wave of suspected lip-synching hit.

On November 30th, bloggers in bilibili released a video entitled "Identification of 12 Songs of Shanghai Concert in May", saying that six songs were suspected of lip-synching, and five of them were lip-synching.

A stone stirs up a thousand waves. Although the concert in the mainland has ended in May, the criticism has not died down. On December 4th, Mayday Weibo, a brokerage company, issued a statement saying that Mayday did not lip-synch during the tour, and the comments on "Mayday lip-synching" on the Internet were malicious attacks, rumors and slander, which seriously damaged the artist’s image. "Our company is actively cooperating with relevant law enforcement departments to carry out investigations, and I believe relevant departments will give us a fair result to set the record straight".

On the same day, the Law Enforcement Corps of the Shanghai Cultural Tourism Bureau said that it attached great importance to the alleged "lip-synching" sensation, and requested the organizers to cooperate with the investigation in accordance with the Regulations on the Administration of Commercial Performances. After the relevant situation was verified according to law, it would respond to the concerns of netizens in a timely manner.

Behind the lip-synching storm is the concert fever that continues to have a high fever this year. The Beijing News Shell Finance reporter combed and saw that since May, Mayday has sung in 12 mainland cities including Beijing, Hangzhou, Wuhan, Shenzhen and Shenyang, with 47 performances. Among them, there were 9 concerts in September.

The country is singing intensively, and the ability to absorb gold cannot be underestimated. The audience of eight performances in Shanghai reached 360,000. Even if the ticket income is calculated according to the lowest fare, the ticket income will easily exceed 100 million.

Mayday agency believes in music statement.

Intensive tour, singing 47 times.

May Day lip-synching is controversial and has been fermented for several days.

On November 21st, the last concert of "I really want to see you" in Shanghai Station on May Day came to an end. There were 8 concerts in Shanghai Stadium this May. According to Mayday Music, the total number of concerts in Shanghai is expected to reach 360,000.

On the second day after the concert, some self-media bloggers said that they had received a submission about lip-synching of the Mayday concert, but it didn’t arouse much splash. Until November 30th, a blogger in bilibili released a video about "Identification of the true and false singing of 12 songs in the Shanghai Concert on May Day". In the video, the blogger pointed out that six songs, Cheers, Being in Love, Being Satisfied, Missing Lover, Writing This Song for You and Don’t Listen to Slow Songs for Sad People, were suspected of lip-synching, and five of them were lip-synching.

Rumors of lip-synching are getting worse. On December 3rd, Believe Music said in Weibo that the Paris Concert on May Day would be broadcast live all the time, "singing for three hours all the time, and really singing until dawn". This voice did not respond positively to the controversy. Some netizens in the comment area said, "The whole live broadcast can’t prove that it was a real singing before."

How hot the performance market has been this year, Mayday is undoubtedly a microcosm.

In May, as the first stop in the mainland in 2023, six concerts were held in Beijing Bird’s Nest on May Day. It is believed that the number of people watching music reaches 100,000 each time, and a total of 600,000 people watch the performance.

According to the rough statistics of Shell Finance reporters, after the Beijing concert, Mayday took a short "rest" for 14 days and then devoted itself to an intensive mainland tour. From May to November, Mayday held the most concerts in September, with a total of 9 concerts. The performance cities included Xi ‘an, Nanjing and Chongqing. Followed by June, October and November, with 8 games respectively, during which they traveled to Beijing, Hangzhou, Guangzhou, Chengdu and Shanghai. In contrast, the least performance was in August, with only three performances.

On December 4th, Shell Finance reporter saw in official website’s "Mayday 2020-2024 World Tour" released by Belief Music that since May, Mayday has performed in 12 mainland cities, with 47 performances, and concerts in many cities often have three or four performances in succession.

It’s not new to travel to many cities in a short time in May. After the concert in Hangzhou ended in June this year, I went to Wuhan to sing nonstop in May, only two days apart. According to the statistics of Shell Finance reporters, during the tour, the longest stop time in May was 37 days, while the last concert in Shanghai was 20 days away from the previous one, and the opening dates of other cities ranged from 3 to 16 days.

It is believed that music is publicly announced. After the Shanghai concert, from November 28th, 2023 to January 14th, 2024, Mayday will also be sung in London, Berlin, Paris and other cities.

One ticket is hard to find, and hundreds of millions of ticket revenues.

Singing frequently in May, the ability to attract gold can not be underestimated.

In August this year, Mayday held three concerts in Quanzhou, Fujian, attracting a total of 120,000 people, about 70% of whom were from other places. The ticket revenue was nearly 100 million yuan, which brought more than 200 million yuan to the local tourism, transportation, catering and accommodation markets.

In November, tickets for the Shanghai Concert on May Day ranged from 355 yuan to 1,855 yuan, with a total of 360,000 participants. Even with the lowest ticket price for eight performances, the ticket revenue can easily exceed 100 million.

Fans are after it, and it is hard to get a ticket for the Mayday concert. The concert held in Beijing on Mayday at the end of May was to sing again after a lapse of four years. A Mayday fan told Shell Finance reporter, "Now, if you want to get tickets, you can only buy them from scalpers at a high price." With the heat soaring, the original price of 355 yuan stands tickets, the sales price reached 900 yuan. However, the original price was unified to 1855 yuan, and the tickets in the front of the infield were priced from 3850 yuan to 8800 yuan according to the distance of the seats.

Shell financial reporters found that Mayday concerts in Hangzhou, Xi ‘an and Guangzhou were exposed to many people selling scalper tickets.

The craze hit, and it also ignited the vicinity of the Mayday concert. Among them, the official single light stick 2.0 is sold in 140 yuan, and the combination price of light stick+protective cover is 190 yuan. It is reported that the light color of the light stick will be converted into different colors with the central control panel during the concert, so it is favored by many fans. It is believed that music, this light stick is sold online and offline through multiple channels.

The reporter of Shell Finance saw that the Taobao store of "Straw Mall", one of the channels, showed that this luminous stick had sold more than 9,000 orders.

In addition, it is believed that the official flagship store of Music Taobao shows that the store is selling 29 Mayday peripheral products. The cheapest one is "Inflatable Cushion Around Mayday FLYTO2021 Concert", which costs 55 yuan, and the most expensive one is "May Day 2023 Noah’s Ark Concert NOW&HERE Limited Edition Gift Box", which costs 635 yuan and has sold more than 100 orders, which is the highest-selling single item in the store.

Concert economy involves complex industrial chain.

Eye-searching shows that Believe Music Culture Media (Beijing) Co., Ltd. was established in 2007 with a registered capital of 2 million yuan, and the legal representative Xie Zhifen holds 92.5% of the shares of the company. Believe Music official website shows that the business of believe music covers record production, artists’ agency and concert production. Its artists include Jonathan Lee, Rene Liu, Mayday and Gaowu.

Shanghai Yunhua Culture Development Co., Ltd., the organizer of Mayday Shanghai Concert, was established in 2019 with a registered capital of 10 million yuan and legal representative Yu Feifei. The company is wholly owned by Shanghai Chinese Culture Performing Arts Co., Ltd.

According to the consulting report of Ai Media, with the resumption of offline concerts, the performance market is picking up in an all-round way. With the promotion of domestic economic development and cultural consumption upgrading, the radiation effect of performance economy continues to enlarge, and the performance market in China is expected to reach 90.346 billion yuan in 2023.

Jiang Han, a senior researcher at Pangu think tank, told Shell Finance reporter that since the beginning of this year, the situation that concert tickets are constantly being speculated but one ticket is still hard to find has aroused widespread social concern. There are multiple reasons behind the popularity of concerts and the high ticket prices. First of all, with the gradual recovery of the entertainment market, a large number of cultural and entertainment needs have been released, and the concert market has been loved by consumers because of its unique live experience and star effect. Secondly, the contradiction between supply and demand in the concert market is obvious, and the number of concerts and seats is limited, which leads to the shortage of tickets, which also leads to the increase of fares to some extent. In addition, scalper speculation has also aggravated the tension of concert tickets.

In Jiang Han’s view, the concert economy is actually a rather complicated industrial chain, involving multiple stakeholders. Among them, the most important source of income is ticket sales. Artists can formulate the ticket price strategy according to their own popularity, the scale and time of the concert, and attract different levels of audience to buy. In addition, commercial sponsorship and derivative sales are also an important source of income.

From the perspective of stakeholders, the chain involved in concert economy includes: artists themselves, brokerage companies, organizers, ticketing agents, sponsors, etc. Each role has its specific functions and interests. There is an intricate interest chain behind the concert economy, and all links are closely linked. If you want to dig gold in the concert market, you need to understand this interest chain and find a suitable positioning and strategy.

Zhang Yi, CEO and chief analyst of Ai Media Consulting, told Shell Finance that the concert economy is sustainable, and the market demand and local consumption demand will stimulate the continued growth of the concert economy, and the growth rate may decline to some extent, but it is also a normal phenomenon.

Regarding the lip-synching storm, lawyer Lan Tianbin, a senior partner of Jiangsu Fade Dongheng Law Firm, told the Shell Finance reporter that if the audience is deceived by lip-synching, the audience has the right to ask the performance organizer to compensate for the losses in accordance with the laws and regulations on the protection of consumer rights and interests after the exit; The performance organizer may claim compensation from the responsible performing arts groups and actors according to law. In addition, the cultural administrative department of the people’s government at the county level shall impose a fine of 50,000 yuan to 100,000 yuan; Those who provide conditions for lip-synching by actors shall be fined between 5,000 yuan and 10,000 yuan by the competent cultural department of the people’s government at the county level.

　　Recently, the research report of relevant institutions pointed out that palm oil will produce more chloropropanol esters and glycidyl esters than other vegetable oils in the process of high-temperature refining above 200℃. Subsequently, some media reports about the toxicity of chloropropanol ester and glycidyl ester in food attracted consumers’ attention. A few days ago, china food and drug administration released the second issue of Food Safety Risk Analysis in 2017, and organized relevant experts to interpret it.

　　Chloropropanol ester is the esterification product of chloropropanol compounds and fatty acids, which can be divided into 3- chloropropanol ester (3-MCPD ester), 2- chloro -1,3- propanediol ester (2-MCPD ester), 1,3- dichloro -2- propanol ester (1,3-DCP ester) and 2,3- dichloro according to the different types of chloropropanol. In recent years, it has been found that 3- chloropropanol esters are detected in cereals, coffee, fish, meat products, potatoes, nuts and hot-processed fatty foods with vegetable oil as raw materials. Especially, the reports of detecting 3- chloropropanol ester in refined vegetable oil and other foods are increasing gradually. Glycidyl ester is the esterification product of fatty acid and glycidyl ester. It is a twin brother with chloropropanol ester, and its formation mechanism is similar. In the process of oil refining, glycidyl ester is usually formed together with 3- chloropropanol ester, and the content of 3- chloropropanol ester is high, so is the content of glycidyl ester. 3- chloropropanol ester and glycidyl ester have become the new pollutants of vegetable oil that attract worldwide attention.

　　Second, some studies believe that these two substances have a low risk of harm to human health.

　　At present, the toxicological research on 3- chloropropanol ester and glycidyl ester is not systematic. The Hong Kong Centre for Food Safety assessed the exposure of people according to the content of 3- chloropropanol esters in biscuits, vegetable oils, cakes and other foods, and concluded that the health risks of 3- chloropropanol esters ingested through the above foods did not need special attention. The German Institute for Risk Assessment assessed the risk of glycidyl ester intake by European people through vegetable oil, and concluded that glycidyl ester intake by the general population through vegetable oil does not pose a safety risk to health. At present, the published research data in China also believe that the risk of glycidyl ester intake by the general population through food such as vegetable oil is low.

　　3. At present, there is no international limit standard for these two substances.

　　3- chloropropanol ester may be hydrolyzed into 3- chloropropanol in vivo. In 2012, the Joint Expert Committee of Food Additives of the Food and Agriculture Organization of the United Nations (FAO)/ World Health Organization (WHO) formulated the tentative maximum daily tolerance (PMTDI) of 3- chloropropanol as 2μg/kg per kg body weight. However, the corresponding limit standards for 3- chloropropanol ester and glycidyl ester have not yet been formulated.

　　Fourthly, optimizing the refining process can reduce the content of these two substances.

　　The results show that the content of 3- chloropropanol ester in oil processing raw materials and unrefined vegetable oil is extremely low, but the content of refined vegetable oil increases significantly, and its content level is related to the types of raw materials of crude oil. Compared with corn oil, rapeseed oil and soybean oil, vegetable oil with pulp as raw material, such as palm oil, is more likely to produce 3- chloropropanol ester. Optimizing the production process can reduce and control the production of 3- chloropropanol ester and glycidyl ester in vegetable oil refining.

　　Therefore, experts suggest: First, strengthen analysis and research to provide scientific basis for whether it is necessary to formulate limit standards for these two substances. Second, according to the characteristics of different oil raw materials, for example, some oils are suitable for cold pressing and some are suitable for hot processing, and different processing methods are established. Moderate processing can reduce the formation of harmful substances and avoid the excessive formation of various risk factors. Third, consumers should pay attention to nutrition collocation and food diversification in their daily diet, and take vegetable oil according to the dietary guidelines of China residents (2016) to avoid excessive intake.

[Photoelectric test after having a car] When it comes to buying a car, many consumers first think of our domestic brand models. Undoubtedly, many domestic electric vehicles have extremely bright data, and the cost performance is also high with the naked eye. Is the joint venture brand car really lacking? Today, we will test the pure battery life of a luxury brand car to see if it can save some face for the joint venture electric car.

Comment on BMW i5 in a word:

Although it is a trolley, the experience of using the i5 is really the same as that of an oil truck, and the key is to save money!

Advantages:

1, the front and rear rows of sitting posture is low, and the riding comfort is strong.

2, energy consumption is relatively low, more than 10 cents per kilometer.

3. The display effect of the rear entertainment screen is outstanding.

4. Good handling performance and accurate steering.

5. Adaptive kinetic energy recovery is easy to use

Insufficient:

1. The comfort in the middle position of the rear row is poor.

2. When the rear entertainment screen is turned on, it will affect the view of the rearview mirror.

This time, the photoelectric model is BMW i5 eDrive35L exclusive, and the battery life of CLTC is 536km. On the basis of this version, our test drive car is equipped with a lot of configurations, including head-up display, rear entertainment screen, Baohua Weijian audio and so on. It stands to reason that the endurance performance of the car should be lower than the official performance. Is this really the case? After fully charging the vehicle, we will start. The relevant vehicle settings and test roads are consistent with the previous tests, and they also appear in the form of tables in the video. You can refer to them.

After nearly 9 hours of continuous testing, we finally gave this BMW i5 exclusive model a run. In the end, its endurance performance was fixed at 600.1km, and the endurance achievement rate was close to 112%, which was more than ten percentage points higher than the previous 98% of Tesla Huan’s new version, and it was the first in the proper list! In addition, the energy consumption performance of vehicles is also excellent, with an average power consumption of only 12.6kWh/100km. These data mentioned above are very useful for a medium and large car. I have to say that ginger is still old and spicy!

However, i5 is not really a hexagonal warrior, and charging speed is its shortcoming. It is built with 400V architecture, and the maximum charging power is about 80kW on a 150kW charging pile. Compared with the current domestic 800V car, it is a bit not enough to see. I think the official doesn’t seem to say what its maximum charging power is, but some foreign media have measured 200kW on 600kW piles. When the next experience time is more abundant, we will also go to measure it.

After talking about the results of BMW i5 photoelectric test, let’s talk about three advantages and two disadvantages found during the test. Advantage 1, sitting posture is low. This is really not easy for an electric car. Whether in the front row or the back row, i5′ s sitting posture is relatively low. The advantage of this design is that drivers and passengers can easily find a comfortable sitting position. Drivers can also better perceive the dynamics of the vehicle.

Advantage 2, adaptive kinetic energy recovery is very easy to use. This is not the first time I have praised BMW’s adaptive kinetic energy recovery. It can automatically adjust the intensity of kinetic energy recovery according to the distance between the vehicle and the front vehicle. The closer it is to the front vehicle, the stronger the kinetic energy recovery is. If this function is used properly, the number of times of braking can be significantly reduced.

Advantage 3: Capacitive induction steering wheel can really make the operation easier, and it is no longer necessary to cater to the steering wheel perception with greater grip strength, as long as you put your hand on it, or even put a few fingers on it, which is in line with human nature.

After talking about the advantages, there are disadvantages. Disadvantages 1. After the rear entertainment screen is opened, it will affect the vision of the rearview mirror, and it is difficult for the driver to obtain the information behind the vehicle from the rearview mirror. If i5 has it, then the problem does not exist. In addition, when the rear entertainment screen is closed, it will also block part of the sky.

Disadvantage 2: Although the i5 is a five-seater car, only four seats can really sit comfortably. The back of the rear middle seat is hard, the head space is small, and there is an obvious bulge in the middle of the platform, which greatly affects the ride. It’s all gone. What’s this bulge for?

OK, that’s all for this BMW i5 photoelectric test. What new car do you want to see in the next issue? Let me know in the comments section.

[car home Nanjing Preferential Promotion Channel] is currently enjoying preferential activities in Nanjing, with a maximum discount of 28,000 yuan. At present, the minimum starting price of this car has dropped to 74,900 yuan. If you are interested in Roewe RX5, you may wish to click "Check the car price" in the quotation form to get a higher discount.

The design of hidden door handles keeps up with the trend, while the 20-inch oversized aluminum alloy wheels make the whole car more dynamic. The slender through taillights and segmented spoilers at the rear also add a three-dimensional effect to the rear.

In the era of small-displacement turbocharging and motor "rushing", as the last car company that insists on naturally aspirated engines, the persistence and awe of control has become the most touching spiritual core of the brand.

On September 26th, Mazda finally unveiled the heaviest "brand" this year, a new generation of compact car Changan Mazda (||). The new car has launched seven models, the price is 115,900-168,900 yuan, which is 10,000 yuan lower than the previous pre-sale price (125,900-165,800 yuan), which is almost the same as the guide price of the old models.

As soon as the price came out, the press conference became a large-scale real fragrance scene for "horse fans", and the industry’s concerns about "overconfidence" in pricing Angkor Wat were swept away.

In fact, for most consumers, 120,000 to 170,000 yuan does not have much advantage, and Mazda’s sales strategy in the domestic market has always been to insist on bicycle profit and not to lower the price. In addition, at this level, there were (||), (|| |), (|| |) and other "big screen" cars before, and then there were diversions. Mazda 3 Angkeira, which is five years old, can still maintain the monthly sales of about 7,000 vehicles. Even if it is replaced soon, it will not affect the sales performance in August. It is not difficult to see the "stickiness" of anquela fans in the domestic market.

On a global scale, (||) is also the best "endorsement" of Mazda brand. The data shows that up to now, the global sales volume of Mazda 3 Angkor Sela has reached 6 million units. This phenomenal car once became a family car totem for sports and manipulation.

Interestingly, at this conference, Mazda responded to the voice of "questioning" from the outside world, listed the so-called "four major sins", and expounded the highlights of the new upgrade.

For example, "the engine is an old model, and the soup is not changed." Although the much-anticipated SKYAIV-X did not arrive as scheduled, the SKYACTIV-G high compression ratio in-cylinder direct injection engine equipped with the new (||)Sela has also been significantly improved. Optimization. By optimizing the piston shape and ignition timing, upgrading the high-pressure three-stage injection technology and installing a high-diffusion injector, the combustion is more complete and the power output is more direct, which fully meets the national sixth B emission standard.

In terms of power, the new Mazda 3 Angkeira continues to be equipped with two naturally aspirated engines of the current model, 1.5L and 2.0L, with maximum horsepower of 117 and 158 respectively.

As we all know, while most car companies are committed to developing small-displacement turbocharged engines that meet emission standards, Mazda, which has always focused on creating driving pleasure, has become one of the few car companies that insist on naturally aspirated engines. In Mazda’s view, a car lost control and almost lost its soul, but at the same time, it had to take into account fuel consumption and efficiency, so SKYACTIV technology came into being.

The so-called Chuangchi blue sky technology, the biggest highlight is to achieve a high compression ratio of the engine, which not only maximizes fuel efficiency, but also saves fuel like a textbook. Since 2015, Sky Sky technology has been widely used in Mazda’s production models. In the following two years, Mazda’s sales in China continued to grow year-on-year. By the end of 2018, China had sold more than 1.14 million vehicles equipped with Chuangchi Blue Sky technology.

Apart from the engine, the most unacceptable thing for fans is that the rear suspension system of the new Mazda 3 Angkeira has been changed from the multi-link independent suspension of the current model to the torsion beam non-independent suspension, which really makes many consumers puzzled. In this regard, Mazda did not hesitate to explain that the SEB suspension on the new car is a technical patent specially developed by Mazda to realize the SKY-VA technology platform. Compared with the traditional suspension structure, SEB suspension has three characteristics: variable cross-section butterfly wing (the diameter of middle section and outer section is different), double-layer structure and seamless welding technology.

However, due to its unique structure, domestic component factories cannot meet the technical requirements. At present, SEB suspension is made by Nippon Steel of Japan, and all of them are imported. Therefore, the statement that the new Mazda 3 Angkeira "changed many connecting rods into torsion beams" to save costs is also "self-defeating".

Another example is the so-called "Japanese cars are unsafe". The new Mazda 3 Angkor Sela comes standard with 7 airbags and knee airbags. At present, this level of products are only equipped with (||)/(||) under TNGA architecture. Secondly, the new car also uses the world’s first 1310MPa high-strength steel cold-formed parts. The utilization rate of 590MPa high-strength steel on the car body is as high as 54%, ranking first in the same class.

Moreover, in terms of safety configuration, the new Angkor Williamson is also equipped with an upgraded i-ACTIV intelligent safety assistance system, including adaptive cruise, lane departure/maintenance, intelligent brake assistance, blind spot detection, reversing warning and other functions.

After the "four major crimes", it has returned to the advantages of Mazda 3 Angkeira, and its most distinctive design is particularly worth mentioning. The new car is equipped with a matrix air intake grille (with active opening and closing function), as well as a newly designed "soul wing" chrome trim strip and LED headlights (fog lamp integrated design). The front face design is simple, atmospheric and refreshing without losing the aesthetic feeling of science and technology. Especially the smart and beautiful side lines, the height of the front is reduced by 30mm, which echoes the rear. All adopt horizontal design, showing the beauty of coupe. On the brand-new Mazda 3 Angkeira, the "Soul Motion" design language, which has won the global annual design car award and the red dot design award for many times, has been upgraded to version 2.0.

On the whole, the new Mazda 3 Angkeira is still the familiar set of "creating blue sky technology+soul design". If you compare it to a fragrant rose, the "thorn" of this rose is equally sharp.

The first thing that bears the brunt is Mazda’s criticized air ride. You know, in terms of size, compared with the previous generation, the new generation Mazda 3 Angkeira adopted a "lateral adjustment" sedan shape. /1445mm, and the wheelbase is 2726mm. However, even if the wheelbase is optimized in data, the rear space of the new Angklin Morson has not been greatly improved, especially the protrusion in the middle of the rear seat, which has a great influence on the rear space. Ride comfort is hard to cater to China consumers who like "big seats".

Secondly, while most car companies are pursuing a cool central control screen and a highly intelligent car networking, Mazda has adopted an 8.8-inch central control screen. As for the in-vehicle system, the biggest role may be to support the interconnection mapping between Apple Carplay and Android Auto.

In terms of sales volume, Mazda’s annual sales volume in China is maintained at the order of 300,000 vehicles, which also makes the brand adhere to the development route of "small but beautiful". Take the brand-new Mazda 3 Angkeira as an example. Like its predecessor, its advantages and disadvantages are equally prominent, just like a rose with thorns, and lovers need not say more.

In today’s involuted automobile market, reducing prices to maintain competitiveness has become an important strategy for many brands, and in luxury B-class cars, many models have made big price cuts. As American luxury brand models, they have reached a very exaggerated price at present.

It is understood that the Cadillac CT5 is currently selling four models of 2024 models, with a guide price of 289,700-341,700 yuan. However, with the increasingly fierce market competition, the price of Cadillac CT5 has been continuously dropping, and many dealers have quoted a straight drop of 80,000 yuan. Recently, we found that in some car trading companies, the low-priced version of this car has nearly fallen below 200,000 yuan.

According to the news, the price of the luxury version with a guide price of 289,700 yuan dropped by 92,000 yuan, and the price of bare cars was 197,700 yuan, which can be said to be a historical low price. The luxury Pro and the premium version are priced at 94,000 yuan and 88,000 yuan respectively, and the bare car price is 205,700 yuan and 232,700 yuan respectively, which are the most favorable prices compared with most dealers.

Looking at the sales volume of Cadillac CT5 in 2024, it shows a downward trend month by month. In September, its sales volume was 2,964 vehicles, down 60.19% year-on-year. It is worth noting that in October 2023, the sales volume of Cadillac CT5 even exceeded 10,000 vehicles, but now the sales volume is sluggish, which is affected by the price war to some extent.

Back to the model itself, as a medium-sized car, Cadillac CT5 has a length, width and height of 4930/1883/1453 mm and a wheelbase of 2947 mm, and its spatial performance is also above the average in its class. In terms of configuration, Cadillac CT5 is equipped with a 33-inch curved conjoined screen, equipped with Snapdragon 8155, and also supports L2-level intelligent assisted driving. In terms of power, the combination of 2.0T+10AT is also attractive, with a maximum power of 174kW and a peak torque of 350 N m..

Generally speaking, the performance of Cadillac CT5 is actually good. Now the low-priced version is less than 200,000. Personally, it is still worth buying. If it were you, would you choose this car?

The requirement for people to buy a car now is not only comfortable, but also other aspects such as configuration, power, materials and workmanship are important reference factors. The richness of the configuration is closely linked to the cost performance of a car, and many people have mentioned it. The following small series will tell you in detail.

Let’s take a look at the appearance of Polo first. The front face style of Polo is very solid, and it is very recognizable with the penetrating net. Coupled with headlights, it adds a bit of exquisiteness. The car is equipped with LED daytime running lights, front fog lights, automatic opening and closing, delayed closing and so on.

Sitting in the car, the overall visual effect of Polo interior is very distinctive, reflecting the sense of design. The steering wheel of the car is eye-catching, made of genuine leather, and its shape is very fighting. Let’s take a look at the central control. The design of the center console is reasonable, which makes the interior style impressive and gives people a feeling full of elegance. Finally, let’s look at the dashboard and seats. The car is equipped with a stylish and generous dashboard, which looks strong in technology. The car adopts a leather/fabric mixed seat, which is wide and thick, further improving the comfort of drivers and passengers.

Polo matched with automatic manual transmission (AT) gearbox, the acceleration time of 100 kilometers is 13s, and the power performance is good, which is completely OK for daily use.

The performance of Polo trunk space is relatively good, the opening size is in line with the positioning of its family car, and the family’s storage needs can be met.
