    With the dream of "automobile power", he led the team to step into the "no man’s land" of scientific research again and again, overcome key core technologies, solve the problem of "stuck neck", and was determined to build "people’s car" with hard core "Chinese core".

    He and his colleagues are quite responsible, and it is difficult to attack the "core". They have successively completed the independent development and mass production of software and hardware of more than 30 controllers, and completed the loading application of 40 million domestic chips on the whole vehicle.

    Thanks to the efforts of him and his team, Wuling Hongguang MINIEV, known as the "people’s scooter" and the world’s single-model sales champion of new energy vehicles for seven times, has increased the localization rate of chips from 6% to 93% in three years.

    As a doctor of "returnees" majoring in combustion science, he has devoted himself to car-making for thirteen years, and always "burns" his burning dreams in the most efficient way in the process of transformation and cross-border.

    He is the "Eight Gui Model", the deputy general manager of the technical center of SAIC-GM-Wuling Automobile Co., Ltd. (hereinafter referred to as SAIC-GM-Wuling), the chief technology officer of control and software, and the deputy director of Guangxi New Energy Automobile Laboratory and professor-level senior engineer Liu Changye.

   "Black! Open up the second pulse of industrial governor. "

    "emergency! Urgent! "

    Put the hour hand back to the end of February 2022. Although it is early spring, it is still chilly. There is a tense atmosphere in SAIC-GM-Wuling. Due to the sudden interruption of the supply of imported chips, the steering controller of key components could not be supplied, and a large number of cars on the assembly line could not be off the assembly line.

    At that time, the "chip shortage" was sweeping the automobile industry. The price of some key components has skyrocketed. Although the price has doubled, it is still hard to find a "core", resulting in a shortage of controllers. SAIC-GM-Wuling introduced more than 40 measures to ensure supply before and after, but it still can’t completely solve the shortage of key components.

    "Before 2019, the controller was regarded as a’ black box’ by everyone, and it was purchased as a whole with parts. We don’t know its internal structure, let alone what chips are carried inside." Liu Changye said that it was not until the "chip shortage" spread in 2021 that enterprises deeply felt the pain of "sticking their necks".

    Production is facing stagnation, and engineers are in a hurry.

    I would rather fight hard than endure it. The grim situation has inspired everyone’s spirit of struggle and aroused the responsibility of "the more difficult it is, the more forward it is".

    "Black! It must be black! Key core technologies must be firmly in their own hands. " Liu Changye thought: "Perhaps the pain point of’ chip shortage’ is the key point to get through the second pulse of industry."

    As a result, the team immediately launched the "Black Box Action" to crack the internal mystery of the "black box" and determined to kill a bloody road on the unknown road of making domestic cars with domestic chips.

    The news of all parties was summarized in the technical center, and one of them attracted the attention of the team: a university in Shanghai with long-term and in-depth cooperation with SAIC-GM-Wuling has made a breakthrough in the application of domestic chips. Full of expectations, Liu Changye immediately went to Shanghai from Liuzhou with a research team of 20 people, and "chased the core" at full speed.

    "Our technology has no precedent for industrialization, and you are about to step into a’ no man’s land’." College experts told Liu Changye.

    The difficulties are far more than that. At that time, the COVID-19 epidemic in Shanghai was tight, so they had to move the scientific research equipment to the hotel, turning the hotel into a crucial place for the team, where they lived and ate. Lacking a testing ground, the underground parking lot became their testing ground.

    After fighting all night and repeated testing, the problems in the software code were found out one by one and corrected one by one. At the same time, Liu Changye also keeps in touch with suppliers, universities and Liuzhou base in production and logistics.

    Race against time. In just 8 days, the software development was completed, which solved the obstacle of related software from laboratory to industrialization. In another 6 days, 100% of the steering controller with domestic chips will be on the production line.

    This speed has shocked the industry.

    In the face of praise from all parties, Liu Changye, who started to set up a team to try to develop controllers at the end of 2019, was not satisfied. "We have mature and complete parts verification capabilities and technology industrialization capabilities, so that the technology of the institute can enter the market and enter thousands of households. There are still many ways to go."

    According to relevant data, in 2022, the global production will be reduced by 4.4 million vehicles due to chip shortage. The success of SAIC-GM-Wuling’s "Black-Breaking Action" ensured that 400,000 vehicles were successfully rolled off the assembly line, driving sales revenue to exceed 10 billion yuan.

    The "Operation Breaking the Black" has boosted everyone’s confidence. After that, Liu Changye led the team to further break through the technologies of software algorithm, domestic chip application and vehicle calibration, and successively completed the independent development and mass production of software and hardware of more than 30 controllers, realized the domestic substitution of 486 chips, and accumulated 40 million domestic chips in the vehicle. Loading application.

    Wade through the deep water and gnaw hard bones. SAIC-GM-Wuling not only solved its own technical problems, but also made domestic chips have rich application scenarios in the field of automobile manufacturing, which promoted the rapid upgrade iteration of domestic chips for vehicles and accelerated industrialization.

   "The software has no accidental failure"

    "There is no accidental failure in the software, and the probability of failure is 0, which is 100%." This sentence of Liu Changye is deeply in the heart of Zhang Zhongjun, the electronic architecture integration manager of SAIC-GM-Wuling Technology Center.

    In the traditional automobile manufacturing process, due to mechanical errors and other factors, there are occasional failures. In a new model development test, the body controller of one of hundreds of cars failed. As usual, Zhang Zhongjun attributed this to "accidental failure" and wrote it into the report.

    Unexpectedly, this was severely criticized by Liu Changye: "There is a problem with the software of this car, and it will definitely appear in other cars! We must find the cause of the problem and give a solution. "

    Although he didn’t quite agree with him, Zhang Zhongjun did as required. Because he knows that Liu Changye’s self-requirements and requirements for product quality are extremely strict.

    "We checked for a week and found that there was a mistake in the software program. We improved the scheme." Seeing the new report submitted by Zhang Zhongjun, Liu Changye finally smiled with satisfaction.

    The phrase "there is no accidental software failure" deeply affects the team-you must not let go of any suspicious problems.

    To overcome difficulties, we need courage and perseverance, and we need to find the right path.

    In November last year, when developing the key safety controller, Wang Wei, the test and experience manager, encountered an unprecedented problem. "This test is bulky and difficult. How to speed up the completion as soon as possible to reduce the supply pressure of the production line? How to solve the problem of high cost of collision test? This makes us feel at a loss. " He said.

    Just when Wang Wei was at a loss, Liu Changye told him, "Don’t be afraid of difficulties, do the right thing."

    Liu Changye broke through the traditional "hard-hitting" crash test method, took everyone to collect more than 30,000 sets of real vehicle data, conducted simulation tests through signal simulation, completed the target task in 10 days, and built a complete signal simulation test system.

    "Software testing is not only qualified acceptance, but also repeated verification in various complex environments, reverse analysis of all possibilities, and efforts to ensure safety and stability." Liu Changye’s words helped Wang Wei find the way to work and the mission of struggle.

    The ancients said, "Who dares to be wrong if the child rate is positive?" With Liu Changye leading by example and setting an example, the team worked as one, and the technical problems of "sticking the neck" were broken.

    "He proposed a long time ago to promote the localization of chips with decoupling thinking, eliminate the problem that chip software and hardware cannot be matched among different enterprises, and make the joint innovation of politics, production, learning, research and use more efficient and forward-looking. At present, the controller and chip application sub-laboratory of Guangxi New Energy Vehicle Laboratory is promoting scientific research innovation and technical iteration under such a concept. "

    "He has a huge knowledge reserve and is called a generalist in science. Once the data didn’t match, he personally deduced the mathematical formula. "

    "He is always full of energy. He forgets to eat and sleep when he does a project. He is often the last person to leave the office. Sometimes he replies to the questions raised by the team on WeChat at one or two in the morning."

    "He is rigorous and meticulous, pursuing Excellence, and his positive and optimistic scientific research attitude infects everyone in the team."

    ……

    In the interview, colleagues outlined the image of this "benchmarking" scientific research worker.

    In fact, Liu Changye is not a talented player born to build a car. From studying physics and combustion to studying engines, to focusing on the development of new energy vehicles and solving the problems of controller development … He constantly challenges himself, which is the intensive work and study for years. Those foreign language documents that have been turned over have been repeatedly tested for thousands of times. The lights that are always on in the office at night and the gray hair on his head are the testimony of the "post-80 s" technical expert’s diligent work and courage to climb the peak of science and technology.

   "Fighting spirit, changing the unknown"

    Interview with Liu Changye, we made an appointment at 8 pm. Through the window of Liu Changye’s office on the 5th floor of Wuling Hongguang Building of SAIC-GM, we can see that he is having a heated discussion with a group of people. It was not until half an hour later that the meeting ended that he came out and said apologetically, "Sorry to have kept you waiting!" "

    Walking into his office, there was a display screen for demonstrating PPT, two pieces of blue tooling, and various materials on the desktop … The most special thing was the form with a wall. "Key Controller Project Plan" and "Key Component Development Plan" … On the table, there are many key nodes, target tasks and development progress, and the time span is from 2020 to 2024.

    "When I have a sip of water, we’ll talk in two minutes." When we sit down, Liu Changye said. At this time, I saw Liu Changye’s eyes through black-rimmed glasses, which was a little tired.

    Before joining SAIC-GM-Wuling, Liu Changye studied physics and combustion, and went to Madrid University of Science and Technology and Delft University in the Netherlands to study. He was selected as the first batch of "National Project for Building High-level Universities" to jointly train doctoral students and went to Lund University in Sweden for further study.

    As we all know, new energy vehicles have no internal combustion engines. However, this expert who studies combustion is the first group of people who invested in the development of new energy vehicles by SAIC-GM-Wuling. Thanks to Liu Changye’s long-term study experience, he has developed his strong learning ability and logical thinking, which has become two sharp tools for him to carry out scientific research in the future. In his view, the internal logic of innovation and research and development are all interlinked.

    When studying in Sweden, the engine laboratory was next to his laboratory. "I was fascinated by the ingenious design of the engine in the laboratory. It was simply a perfect work of art." Speaking of which, Liu Changye’s eyes sparkled.

    After that, Liu Changye often went to the laboratory next door to observe. During the long-term exchanges, he deeply felt the gap between China and developed countries in car-making technology, and the seeds of dreams were quietly sprouting in his heart.

    "My parents are industrial workers and always respect and support my choices." The cold wind in Sweden gradually receded, and the moat of the castle began to shine, and winter went to spring. Standing at the crossroads of life, Liu Changye was a little confused in his heart until he met this engine. "I grew up in Liuzhou’s strong industrial and cultural atmosphere and watched the automobile industry surge. I am also the son of a worker, and I am always eager to use what I have learned. " Liu Changye immediately decided to go back to Liuzhou to work and devote himself to automobile research and development.

    In 2010, Liu Changye joined SAIC-GM-Wuling and was the second doctor recruited by the company.

    Nowadays, it has become the norm for "returnees" to return to their hometowns and doctors to enter the factory. Among the 4000 engineers in SAIC-GM-Wuling Technology Center, there are 26 doctors.

    Among the four apprentices Liu Changye is currently taking, there are two doctors. He also integrated the enlightened education of his parents into the process of mentoring.

    Alvin Wong, a post-90s doctor, is an expert in software testing and one of Liu Changye’s apprentices. "He always works late, but he never asks us to do the same." In Alvin Wong’s eyes, Liu Changye’s "being a teacher and a friend" is an example for learning and a yardstick for correcting mistakes.

    "When I first entered the company from campus, I always wanted to prove myself. In order to make an annual summary report, I want to present it in a bright way. " Alvin Wong said. However, Liu Changye told Alvin Wong that the road is simple, and it is not necessary to engage in fancy things in scientific research, but to be down-to-earth.

    Adhering to the fine tradition of "working hard and striving for self-improvement" and aiming at mastering key core technologies, SAIC-GM-Wuling is accelerating its global layout on the new track of new energy vehicles. A number of new energy vehicles, represented by Wuling Air ev, which shined brilliantly at the G20 Summit held in Bali, Indonesia in 2022, are shining frequently on the international stage with the expectation of Liu Changye and the team, and realizing the output of technology, standards and industrial chain.

    Under the leadership of Liu Changye, SAIC-GM-Wuling has set up a high-level scientific research team in the field of localization of automobile controllers and chips. On the stage of international competition, Liu Changye firmly believes that the self-controlled technology and reliable product quality will make the road for China automobile to "go out to sea" wider and flatter.

    In Kan Kan, Liu Changye described his dream of "automobile power".

    "Sorry, actually, I haven’t had dinner yet, and my brain can’t turn around …" At the end of our interview, Liu Changye said apologetically again. Only then did we notice that the sweets and biscuits on the table were used to satisfy his hunger when he was busy.

    Fighting spirit, changing the unknown.

    Out of Liu Changye’s office, there is such a sentence printed on the head-on wall. Looking back on the interviews in the past few days, from Liu Changye and his team, we can see the hope and confidence of China automobile industry to lead the world in the new energy track. (Li Bin Rongyao)

Choosing 7kW or 11kW for the zero-running charging pile depends on the actual AC charging power supported by your car. At present, most models of zero-running only support 7kW charging. Generally speaking, it is enough to choose 7kW. However, if you consider the need of upgrading and changing cars in the future and have applied for a 380V meter at home, you can also consider buying 11kW charging pile.

Comparative analysis of 7kW charging pile and 11kW charging pile for your reference:

Charging speed:

7kW charging pile: It belongs to the conventional household slow charging power, and can charge the vehicle about 7 kWh per hour. If the battery capacity of your vehicle is not particularly large and there is no special requirement for charging time, the 7kW charging pile can meet the daily charging needs.

11kW charging pile: The charging speed is relatively fast, and the charging amount per hour is more than that of 7kW charging pile. It is suitable for some users who want to charge more power in a short time. However, the premise is that the vehicle itself supports the charging power of 11kW. If the vehicle does not support it, the charging power will be limited and the charging speed of 11kW cannot be reached.

Installation conditions:

7kW charging pile: Generally speaking, the voltage of 220V can meet the use requirements of 7kW charging pile, and the requirements for the circuit are relatively low. It is relatively easy to install in most household electricity environments, and it is not necessary to carry out large-scale transformation of the circuit.

11kW charging pile: It usually needs 380V three-phase electricity to support its normal work. If your community or family does not have the power supply conditions of three-phase electricity, it may not be possible to install 11kW charging pile. When applying for the installation of charging piles, the power department will evaluate whether it can be installed according to your electricity consumption and the power facilities in the community.

Price cost:

7kW charging pile: The price is relatively cheap, and the cost of purchasing the charging pile equipment itself or in the installation process is relatively low. Moreover, due to its low power, in the process of daily use, the power consumption is relatively small, and the electricity expenditure is relatively small.

11kW charging pile: Due to its high power, the cost of equipment, materials and labor required for installation may be higher than that of 7kW charging pile. And in the process of use, higher power may lead to an increase in electricity consumption.

Future applicability:

7kW charging pile: It can basically meet the daily charging needs of most zero-sports cars, and most new energy vehicles on the market now support 7kW AC slow charging, with good compatibility. If you don’t plan to change vehicles frequently, or the future vehicle charging needs are similar to those of existing vehicles, 7kW charging pile is a safe choice.

11kW charging pile: It has better compatibility and flexibility. If you may replace different brands or models of new energy vehicles in the future, and these vehicles support higher power charging, then 11kW charging pile can better meet the future charging needs. When purchasing 11kW charging piles, pay attention to purchasing charging piles that can be compatible with 7kW. Many third-party charging piles can’t be compatible with 7kW. If it is necessary to be compatible with 7kW when changing models in the future, the charging power will be reduced to only 3.5kW, and the charging will be very slow. It is recommended to consider the nebula 11kW charging pile. Their 11kW is compatible with 7kW. If you are a Tesla (supporting 11kW) and want to change to a zero-run car (supporting 7kW), then only one pile will enable Tesla and zero-run to reach the highest charging power when charging, and one pile will be used as two.

To sum up, if you don’t require high charging speed, the power supply conditions in your area are suitable and you want to save costs, then 7kW charging pile is a good choice; If you are looking for faster charging speed, have the power supply conditions of 380V three-phase electricity, and are willing to bear higher equipment and installation costs, then 11kW charging pile may be more suitable for you.

The application process of household charging pile electric meter is as follows:

Preparation before application:

Material preparation:

Identity certificate: the applicant’s valid identity document, such as ID card. If the non-head of household applies, it is recommended to fill in the power of attorney and entrust the family to handle it. Both ID cards need to be prepared.

Parking space certificate:

Self-owned parking spaces need to provide proof of parking space ownership, such as real estate license, parking space purchase contract, etc.

A lease agreement should be prepared for renting a parking space, and the lease period should generally be more than one year (including one year).

Proof of car purchase: any one of the electric car purchase intention agreement, car purchase invoice, electric car driving license, etc. is used to prove that you own an electric car.

Property or related certificates: for the community owners, a written certificate that the property agrees to use the charging facilities for installation or an agreement on the use of the charging facilities for new energy vehicles is required; No property management area by the industry committee, neighborhood committees or neighborhood offices issued relevant certificates. The installation of charging piles in rural self-built houses requires the seal of the village Committee to agree to the construction opinions.

Determine the installation conditions:

Confirm that there is a power distribution room near the parking space, and there is a distribution box of the State Grid in the power distribution room, and there is space and capacity for installing electric meters.

Communicate with the property in advance to find out whether the charging pile can be installed in the residential capacity.

Application process:

Online application:

The provinces under the jurisdiction of the State Grid (North China, East China, Central China, Northeast China and Northwest China) download the "Online State Grid"; The provinces under the jurisdiction of China Southern Power Grid (Guangdong, Guangxi, Guizhou, Hainan and Yunnan provinces) download "Southern Network Online"; Download "Mengdian E Home" in the jurisdiction area of Inner Mongolia West Power Network.

After registering and logging in, click the "Electric Vehicle" section on the home page, then select "Charging Piles for Installation", provide the required materials according to the step prompts, and select "Charging Piles for Electricity" for power connection requirements.

Offline application: Go to the local business hall of State Grid or China Southern Power Grid, get and fill in the Application Form for Charging Piles, and submit the application form and application materials.

Audit and installation:

Review: the power supply department will review the application after receiving it, which usually takes 1-5 working days. The contents of the audit include the authenticity and completeness of the application materials, and whether the capacitance of the community meets the installation requirements.

On-site investigation: after the approval, the staff will be arranged to conduct on-site investigation to determine the installation location of the electric meter, and the property electrician may be required to cooperate to open the power distribution room.

Installation: The installation of electric meters is free, and it usually takes 2-3 working days to complete. Keep the phone open during installation so that the staff can contact in time.

Power grid companies in different regions may have slight differences in specific processes and requirements. It is recommended to consult the detailed requirements of local power grid companies before applying to ensure a smooth application process.

When new energy owners choose 11kW smart charging piles, nebula charging piles are the best choice. The following are the detailed reasons.

Home charging pile brand recommended nebula charging pile

Strong compatibility, one "pile" is multi-purpose

Xingyun 11kW charging pile is compatible with 7kW, which has obvious advantages. It can adapt to different brands of new energy vehicles such as Tesla, BYD and Wenjie. When there are vehicles with different charging power requirements at home or changing cars in the future, the nebula charging pile can cope with it. When other third-party 11kW charging piles charge 7kW vehicles, the power is often greatly reduced, and Xingyun can ensure that each vehicle can reach the appropriate charging power and maximize the utilization of resources.

Safe and secure, worry-free charging

Safety is the key to charging. Xingyun charging pile adopts the R&D system and manufacturing standards of vehicle regulations, and the fuselage is made of flame retardant material. The charging gun head is made of excellent material, the coating design is exquisite, and it is durable for plugging and unplugging. It has ten protection functions, including short circuit, lightning protection, leakage, overvoltage, overcurrent, undervoltage, overheating, grounding, emergency stop, and rain protection, ensuring the safety of charging in all directions, so that users have no worries.

HarmonyOS Zhilian

If the mobile phone is HarmonyOS system, it will be very convenient to use. Xingyun charging pile supports Huawei’s mobile phone NFC at a touch, and can also be controlled by the "Charging Meow" APP and the "Smart Life" APP. It is easy to remotely control, make an appointment for charging and set charging parameters, and you can control the charging situation even if you are thousands of miles away.

Bluetooth inductive charging

There is no need to worry about the poor signal in the underground garage. Bluetooth function allows users to connect automatically when they are close to the charging pile, realizing plug-and-play charging or reservation charging, which is not affected by the signal.

Idle time sharing function

When the charging pile is idle, it can provide convenience for other car owners through the shared platform, and at the same time, it can also get benefits.

Scheduled charging

By using the scheduled charging function, the charging time can be flexibly set according to the electricity consumption habits and the local peak-valley electricity price policy. For example, charging at night during valley hours can not only enjoy low electricity price, but also save energy and environmental protection, and also save charging cost, which is in line with the concept of green travel.

Equipment doctor

The equipped equipment doctor function can play a big role in the event of failure. Users can self-check and upload fault codes quickly through this function, and nebula technicians can quickly check problems and provide solutions in time, which can improve maintenance efficiency, reduce inconvenience caused by faults and ensure smooth charging process.

Current regulation

In the face of power grid fluctuation, peak power consumption or voltage instability in remote areas, the current regulation function can adjust the current and reduce the power to avoid direct charging interruption. It can adapt to various complex environments, ensure stable charging and ensure the continuous and stable charging of vehicles.

APP remote control and data statistics function

Remote control can be realized through the APP, and the charging pile can be operated no matter where you are. At the same time, the APP can make detailed statistics on charging data, such as charging time, power, historical charging records, etc., so that users can clearly understand the charging situation and cost, and it is convenient to manage the charging process.

Toyota, as the main model of FAW Toyota’s mid-sized car market, has also achieved great success in the domestic car market. From January to June this year, the cumulative sales of Toyota Asian Dragon exceeded 27,000 units. However, in order to gain more sales and market share, FAW Toyota has launched a new generation of Toyota Asian Dragon models (2024 models). The new car has a lower guide price and higher configuration. So is the new generation of Toyota Asian Dragon worth buying? Please continue to read below.

Price part: Positioned as a mid-sized car FAW Toyota Asian Dragon price range of 17.88-25 6,800 yuan, its entry price is 21,000 yuan lower than the old model, the top model is also cheaper than the old model 23,000 yuan, it can be seen that the host factory is full of sincerity. The new car not only provides 2.0L and 2.5L oil-electric hybrid system, but also provides 2.0L naturally aspirated engine for our consumers to choose to buy.

Appearance part: In my personal opinion, the Toyota Asian Dragon’s vehicle design is still very successful. At least no one has called it ugly because of its appearance so far. Although it is a 2024 model, the appearance continues the design concept of the old model as a whole. In order to meet the aesthetics of more consumers, the 2.5L car provides a star diamond grille shape, and the interior is complemented by rhombus format elements. The visual effect is more delicate and sporty, while the 2.0L model uses a horizontal grille design to look more atmospheric.

Even for entry-level models, Toyota Asian Dragon still provides LED near and far light sources, LED daytime running lights, adaptive near and far light, auto front light, LED front fog light and headlight height adjustable functions that can fully meet daily commuting needs, while the high-end models are more abundant in configuration.

The side design is what I admire the most. The proportions are well controlled, the lines transition naturally, and the smooth waist line is integrated into the lower chord of the window, which reduces the visual center of gravity of the body. The 18-inch rims equipped with the entry model are not too large for the size of the body. Fortunately, the multi-spoke style fits well with the whole, and the momentum of the vehicle walking is just right. The top line has some hatchback elements in it, and the gentle slip line will not affect the head space of the rear passengers. The taillights are novel and three-dimensional in shape, and the effect of the light guide width indicator is unforgettable after lighting, not to mention the full LED light source.

In terms of chassis suspension, the structural combination of front McPherson independent suspension + rear E-type is adopted, and the suspension setting is soft, which is mainly reflected in the high-speed following, and the acceleration and braking can feel the front and rear pitch of the body posture more obviously. The soft suspension setting is still very suitable for such a big car, after all, who would take such a big car to drive intensely. When passing through some large undulating roads and fine vibration sections, the body is particularly calm and has a strong sense of heaviness.

In addition, the steering wheel can convey to the driver a more effective sense of the road, while those unpleasant vibrations are still shielded from the car. The front of the car is obviously more willing when entering corners. With the traction of the front axis, driving a medium-sized car with a length of nearly 5 meters on the road has become a happy thing.

In terms of size, it is positioned as a medium-sized car, and the body size is also the most concerned part of consumers. The length, width and height of the new car are 4990/1850/1450mm respectively, and the wheelbase reaches 2870mm. The height of the experiencer is 178cm. After adjusting the seat to a position suitable for driving, there is a punch margin in the head, and the front seats remain unchanged. When it comes to the rear, the head space is four fingers, and the leg space is more than two punches. The trunk space of the Toyota Asian Dragon is relatively regular, and the rear seats support 4/6 ratio reclining, which is practical.

In terms of seats, the Toyota Asian Dragon’s seats are very comfortable. The large area of perforated leather enhances the air permeability of the seats. The material and shape of the rear seats are the same as those of the front row. The riding experience is also very comfortable, but the headrest in the middle position cannot be adjusted in height, which should not be saved. In addition, the central platform is raised higher, and the riding experience in the middle of the rear row is not very friendly.

In terms of interior, the central control adopts a wraparound design, the center console occupies most of the space for drivers and passengers, and the visual effect is not too spacious. The layout of the air-conditioning area is very regular, the rectangular buttons look particularly refreshing, and the function distribution is clear at a glance. The steering wheel is of the same style, with a home shape, a moderate size, and an optimized grip for the three or nine o’clock direction. Most of the materials of the central control are still textured, but the hard plastic in the blocking position is almost interesting to the touch and visual effect.

In terms of power, it is equipped with a 2.0L and 2.5L gasoline-electric hybrid and a 2.0L naturally aspirated engine, of which the 2.0L naturally aspirated engine has a maximum power of 127kW, which is matched by a CVT continuously variable transmission, while the 2.5L hybrid version of the engine has a maximum power of 136kW. It is worth mentioning that the 2.0L hybrid version will be equipped with a gasoline-electric hybrid system composed of a 2.0L engine + motor. The maximum power of the engine is 112kW, and the drive motor also has 83kW, reaching 145kW (197 horsepower). It has a good performance in terms of power performance and fuel economy.

Full text summary: The above is our comprehensive analysis of the 2024 FAW Toyota Asian Dragon. It can be seen that it has a good price/performance ratio, atmospheric design, spacious space performance, rich configuration, excellent power performance, and fuel economy. This allows you to have a comfortable experience while driving and sitting. Therefore, we feel that the FAW Toyota Asian Dragon is still worth buying.

If you’re looking to buy a mid-size sedan in 200,000, look no further than the Toyota Asian Dragon.

Recently, the love life of the high-profile celebrity couple Deng Chao and Sun Li has become a hot topic in the media. According to the revelation that Deng Chao is suspected of having an affair with a young model aged only 19, their marital status has once again attracted public attention. However, is this news true? Let’s explore this topic together.

First of all, we need to make it clear that, as a large language model, I cannot make judgments about anything that is not proven, so I can only provide some possible scenarios for discussion here.

On the surface, Mr. Deng and Ms. Sun have been model couples in the entertainment industry, raising two children together and supporting each other in their careers. But in recent years, rumors of their marital problems seem to have been growing. For example, it has been pointed out that they are not close in public and even interact less and less on social media. These signs have raised questions about whether their relationship is in trouble.

In the face of these rumors, Sun Li chose to post a meaningful Weibo post late at night with the content of "Goodbye Marriage". The Weibo post quickly caused a heated discussion among netizens, with many speculating whether she was suggesting that her marriage with Deng Chao had come to an end. However, many people also believed that this was just a way of expressing, and did not necessarily mean that her marriage was really in trouble.

For his part, Mr. Deng did not comment on the matter, though he appeared to be trying to prove that their marriage remained strong by sharing photos of his family life on social media.

In short, at present, we cannot determine whether Deng Chao really cheated on the young model, and what Sun Li’s mysterious Weibo means. Perhaps only they can answer these questions. Here, we also hope that they can handle their own personal affairs and give their children a healthy growth environment. At the same time, we also appeal to the majority of netizens to view these rumors rationally and not to over-interpret and spread them, so as not to cause unnecessary trouble to the parties involved.

Original title: Xiaodu at home smart speaker video review, smart speaker with screen is really amazing

foreword

I have been paying more attention to the smart speaker category, and now smart speakers have been fully integrated into my life.

About a year ago, Amazon released a smart speaker with a screen Echo Show, and domestic smart speaker pioneer JD.com – Ding Dong also released a smart speaker with a screen at CES earlier this year, Ding Dong PLAY, but it actually became a product and officially launched in China. It is the "Xiaodu at home" that you want to experience today.

Smart speakers should not have a screen, which used to be a very popular discussion after Amazon released the Echo Show. Many technology media came out to post articles, with praise and criticism, and it seemed that the criticism was greater than the praise. But whether the experience of having a screen is good or not, please follow me.

unpacking

The packaging of "Xiaodu is at home" is quite simple, and the pure white hard carton is printed with hot silver. The product name on the front is marked as jointly produced by Baidu and Xiaoyu at home.

On the back of the box is some necessary information for product packaging, and there is no excess.

Open the heaven and earth cover, and what you see directly inside is the main body of the fuselage embedded in the blister packaging.

Take out the main unit, and there is a small box below to put the transformer.

Transformer output power 12V 2A.

exterior display

Xiaodu has four body colors to choose from at home, and I chose a bright "Rock Red".

From the front, Xiaodu’s appearance at home is quite similar to that of the Echo Show, except that the position outside the screen is completely wrapped in fabric material, which is more visually gentle

The side and back are quite different from the Echo Show. It feels a bit like a traditional cylindrical speaker with a screen on the front. There is a power switch on the top. Since the screen is a touchscreen, there is no need to add too many buttons, and most operations can be performed directly on the touchscreen.

There are silicone foot pads at the bottom, and there are Micro USB ports and power ports in the semi-circular hollow position.

The weight of the whole machine is not heavy, 0.834 kilograms, about one and a half catties.

Town Building Map

After unpacking, even if you enter the real experience evaluation process, put a map of the town building before that. This picture is not to brag about how many smart speakers I have, but to show that I have indeed experienced and tried most of the smart speakers on the market. After a long time of use and experience, I have learned about the current mainstream technical level of the smart speaker category, and can objectively evaluate the quality of a product. The following review and experience are based on my experience of using the vast majority of smart speakers on the market.

boot configuration

Press and hold the top power supply for three seconds to turn it on, and the boot screen shows the product name, "Xiaodu Smart Video Speaker at Home", jointly produced by Baidu and Xiaoyu at Home.

Due to the screen, it is much easier to connect to Wi-Fi. You don’t need to open the APP anymore. You can directly connect to the Wi-Fi network like operating a Pad.

After the device is successfully connected to the network, the APP will be installed and the device will be activated by scanning the code through the APP.

When you open the APP for the first time, there will be some introductions to the selling points of this product.

Xiaodu used Xiaoyu’s user system at home, because I have used Xiaoyu at home before, so I can log in directly.

After logging in to Xiaodu Home, you need to bind your Baidu account again to get Baidu-related services. After the binding process is completed, there will be a short introduction video to watch.

After the APP logs in and scans the code, the binding process is completed. The first user to bind is the administrator of the device. After the device is activated, there is also a short demonstration video and asks if one call is turned on. To turn on this function, the mobile phone can also see the screen shot by the device without the need to answer the device, similar to the function of remote monitoring.

I forgot to take a comparison of the size of the reference object before, so I added it here. I think the volume is more suitable.

practical experience

Several icons on the main screen represent skills introduction, calls and messages, Wi-Fi connection, time, air quality, family member avatars, etc.

Xiaodu used "Xiaodu Xiaodu" as the wake-up word at home. After waking up, all the content Xiaodu heard at home would be converted into text and displayed at the bottom of the screen. Through this information bar, users could intuitively see whether Xiaodu accurately recognized the user’s voice content at home.

With a screen, the information that can be conveyed has an extra dimension. In addition to voice broadcasts, most of the information will also be converted into images and displayed on the screen.

When listening to music, not only can the album cover be displayed, but also the lyrics can be scrolled to display, which is very cool.

Now that he had a screen, he could play videos. Xiaodu was at home and fully connected to the iQIYI platform. All content on iQIYI could be retrieved and played directly on Xiaodu’s home. If he was not an iQIYI member, he would normally watch a 60-second advertisement.

Xiaodu is equipped with a seven-inch screen at home with a resolution of 1024 × 600. The picture quality is relatively average, which is enough for video calls, but it is not recommended to use this device for a long time to watch video content. However, in some scenes, it is quite convenient to have this small screen to watch the content. For example, watch the explanation when cooking, and watch the tutorial when accompanying the child to do crafts. In addition, Xiaodu supports DLNA video output at home, and can voice-demand content and complete the screen projection.

The way to log in to iQIYI is to click Member in the upper right corner to skip the advertisement when an advertisement appears. At this time, the QR code will appear on the screen. Use the iQIYI APP and scan the code to associate the account relationship.

You can make video or voice calls directly at home through Xiaodu. If the other party is already a family member, you can directly initiate a video call or voice call over the Internet without a separate charge. If you just dial a normal phone number, you will need to pay the call fee. Each device comes with 60 minutes of free phone calls, which can be paid later.

actual experience video

Let’s play a practical video. It can be seen that Xiaodu’s recognition accuracy and reaction speed at home are both excellent.

APP

In terms of the APP, users who have used Xiaoyu at home can see that this is basically Xiaoyu’s APP at home, with slight modifications in some small places. But that’s fine, after all, Xiaoyu has been on the market for a long time, and the App has been polished for a long time.

The app is divided into three tabs, namely Voice Skills, Family Interaction, and Discover More.

Language skills are mainly used to explain the functions of this device and related voice commands. Just look at the long picture below.

Before Xiaoyu was at home, his main focus was family care and company, so the function of this family circle was also simultaneously translated to Xiaodu at home.

Family interaction includes audio & video calls, family member management, smart capture, and family albums. For relevant settings, you can see the screenshot below, and the following video will also show you the actual use effect.

Discover more about some settings for devices and permissions. Among them, the child protection function is very intimate. You can set which users can be on-demand, and force a break after 30 minutes of video playback.

Smart speakers need some smart home linkage functions, and Xiaodu’s smart home functions at home can only be regarded as a little bit of water. Devices that can be connected are on the right side of the picture below. There are some devices connected through Broadlink in my home that can be bound to an account and controlled, but the control is limited to basic functions, and there are no customization and scene-related settings.

A summary of Xiaodu’s experience at home

Advantages:

1. With the screen, the content that can be displayed has expanded a lot. In addition to seeing iQIYI videos, you can see lyrics when listening to songs, spelling when asking English, and corresponding pictures or even small videos when checking the content.

2. In addition to being more informative, it also reduces distrust of voice devices. (Here I want to explain what distrust there is with devices that did not have a screen before. For example, if I ask a long mathematical calculation, I believe that as long as the speaker can understand it, it will be correct. But I am not sure if a long mathematical calculation speaker really heard it correctly, and the result reported to me in the end is really what I want to calculate. And with the screen, you can intuitively see the complete calculation formula I said on the screen.)

3. The APP has been relatively mature and has stable functions after being polished by Xiaoyu at home before.

4. Focus on building relationships in the family circle, share photo albums and videos, and bring family members closer together.

The price of 599 does have a significant impact on the market for congeneric products.

Deficiency:

1. As a smart speaker, sound quality is a weakness.

2. I didn’t find the function to disable the microphone. I don’t know if it’s really not there or if it’s hidden too deeply.

3. Smart home is a touch of the water.

For the development of intelligent driving, 2023 is a stormy year.

On the one hand, after the software and hardware technical framework of intelligent driving was gradually established, head players began to promote the test and landing of urban or high-speed navigation-assisted driving in their production models, and were exploring business models based on software subscription.

As a result, commercial landing has become a key word for smart driving in 2023.

On the other hand, the landing of urban navigation-assisted driving is not achieved overnight. In addition to the technical framework, we need to make great efforts in engineering and end-user experience. Therefore, players are also trying their best to integrate some more practical algorithm models into the project landing, and the integration of large models is also becoming a bright spot.

Of course, the current technological development of intelligent driving is far from mature. Therefore, pioneers of intelligent driving like Tesla are also verifying the realization effect of end-to-end algorithms, and even exploring the technological development direction of the next generation of intelligent driving.

Under the above background, the intelligent driving industry in 2023 can be said to be a competition among Qian Fan. Major players have made great efforts in several intersecting dimensions such as technical exploration, business landing and mental occupation, and staged a colorful annual drama of the smart driving industry.

Therefore, standing at the end of 2023, we also made an annual inventory of the top ten important events in the smart driving industry this year, hoping to outline the general outline of the development of the smart driving industry.

1. Huawei ADS 2.0, seeking a balance between technology and cost.

On April 16th, 2023, Huawei ADS 2.0 was officially released.

As a new generation intelligent driving solution of Huawei, Huawei ADS 2.0 also adopts the network architecture of BEV+Transformer in terms of software algorithm, and joins the two networks of GOD (General Obstacle Network) and RCR (Road Topology Reasoning Network), which are the first laser fusion in the industry.

It is worth mentioning that, in terms of hardware, Huawei ADS 2.0 adopted the MDC 610+single lidar scheme in the landing process of the cross-border model; Compared with the MDC 810+three lidar scheme adopted by ADS 1.0, Huawei ADS 2.0 no longer only emphasizes computing power and sensing hardware, but also considers the balance between landing cost and landing experience from the perspective of engineering.

From the perspective of the industry, the launch of Huawei ADS 2.0 not only established Huawei’s head position in the process of smart driving landing in 2023, but also conformed to the landing trend of smart driving industry in 2023: on the basis of hardware capabilities, it emphasized the balance between engineering capabilities, user experience and cost.

2, Tucki G6 Max version, lowering the threshold for urban smart driving.

On June 29th, 2023, Tucki G6 was officially released. Its starting price was 209,900 yuan, and the starting price of Max version was 229,900 yuan, with a price difference of 20,000 yuan. On the hardware level, Tucki G6 Max version is equipped with 31 high-performance intelligent driving sensors including laser radar and dual Orion-X chips with a total power of 508 TOPS.

This means that under the extremely fierce market conditions at that time, through the Tucki G6 580 Max version, users can buy an intelligent electric vehicle supporting the city navigation and driving assistance function at the lowest price of 229,900 yuan.

Tucki G6 Max version, with a starting price of 229,900 yuan, broke through the bottom line of the price of navigation-assisted driving models in the whole industry at that time, and also lowered the landing price of navigation-assisted driving in the whole city to a great extent. From the perspective of industry, Tucki G6 not only vigorously promoted urban navigation-assisted driving to ordinary users, but also set a new value benchmark for mass production in the field of intelligent driving at that time.

3. BYD released the advanced intelligent driving assistance system "Eye of God".

On July 3, 2023, at the Tengshi N7 listing conference, BYD’s advanced intelligent driving assistance system "Eye of God" was officially released.

At the same time, Tengshi N7 took the lead in BYD’s world-first "Eye of the Gods" advanced intelligent driving assistance system. Based on "Eye of the Gods", Tengshi Pilot provided two intelligent driving assistance platform schemes: the standard version of intelligent driving assistance system and the advanced version of intelligent driving assistance system.

As the initiator of BYD’s intelligent second half, the release of Tengshi N7 means that BYD has also taken a key step in the intelligent level, especially the intelligent driving level. Considering BYD’s position in the whole China automobile industry, BYD’s embrace of intelligent driving has also promoted the whole automobile industry to embrace intelligent driving in a certain sense.

4. Musk conducted an end-to-end live broadcast of FSD V12.

On August 26, 2023, Musk conducted a live broadcast on the social platform about the intelligent driving ability of FSD V12; Different from the software algorithm scheme adopted by Tesla FSD in the past, FSD V12 adopts an end-to-end scheme.

Judging from the content of the live broadcast, whether it is an unprotected left turn, pulling over, avoiding pedestrians, etc., the vehicles in the live broadcast have shown a high degree of completion, which is still remarkable in general.

In this live broadcast, Musk only took over once; At an intersection, according to the set route, the vehicle originally planned to go straight. However, when the street lamp in front showed that it could turn left, the live Model S suddenly started to move forward. Fortunately, Musk took over the vehicle in time.

For this takeover, Musk said that this is why this version has not been released. But for the smart driving industry, this live broadcast is the first time that Tesla has demonstrated the actual performance of the end-to-end algorithm architecture for the whole industry; Soon, Tesla began to further iterate the software algorithm.

5. Tucki added the big model to XNet 2.0 perception architecture.

On October 24th, 2023, on the 5th Xpeng Motors Science and Technology Day, Xpeng Motors released XBrain, the ultimate architecture for intelligent driving in all scenes, including XNet 2.0, a new generation of sensing technology architecture, and XPlanner based on neural network regulation.

In XNet 2.0 perception architecture, Tucki joined the dynamic BEV network and static BEV network, and joined the visual occupation network. At the same time, XNet 2.0 has also added the blessing of a large model, which can read text information, have the concept of time and space, and understand the traffic elements with different urban characteristics.

As a result, Tucki’s XNet 2.0 has become the first perceptive framework in the industry with the ability to perceive time and space by using a large model. This is Xpeng Motors’s latest exploration in improving the perception of intelligent driving, and it also has great enlightening and weathervane significance for the whole industry.

6. Extreme Leap 01 adopts the only "pure vision" advanced intelligent driving scheme in China.

On October 27th, 2023, Extreme Yue 01 was officially released. Different from many domestic vehicles with urban navigation-assisted driving functions, the Extreme Yue 01 is not equipped with laser radar, making it the only vehicle in China that adopts the "pure vision" scheme to realize urban navigation-assisted driving, and it can be used immediately after release.

Specifically, based on Baidu Apollo’s full set of advanced autonomous driving capabilities and the empowerment of the safety system, Ji Yue adopted the algorithm architecture of BEV+Transformer+OCC occupying the network—which means that under the industrial background that urban navigation-assisted driving has been mass-produced with the help of laser radar, Ji Yue decided to open up a "pure vision" technical path in this track.

From the perspective of the industry, the release of Extreme Yue 01 also means that in the process of China’s intelligent driving industry landing, Extreme Yue has become the only OEM in China that chooses the pure visual route for high-level intelligent driving.

7. L3 and L4 models are officially qualified for road testing.

On November 17, 2023, a number of competent departments jointly issued a notice on the pilot work of intelligent networked vehicle access and road traffic. This means that, from a policy perspective, intelligent networked cars equipped with L3 and L4 functions are finally qualified to go on the road.

From the policy itself, the requirement of L3 and L4 testing itself is to select intelligent networked automobile products with automatic driving function with mass production conditions and carry out pilot projects on the road in a limited area; At the same time, vehicles used for transportation operations must meet the operational qualification and operational management requirements of the transportation authorities. Therefore, for L3 and L4, the competent authorities take a very cautious attitude of support.

It is worth mentioning that within one month after the announcement of the above notice, relevant models under many automobile brands, including BMW, Mercedes-Benz, Extreme Fox, Zhiji, Deep Blue, Aouita, Celeste, Tengshi, etc., have obtained corresponding autonomous driving test licenses.

8. Based on the big model, Tesla announced that it will be the next generation of autonomous driving.

On December 2, 2023, Tesla’s official social media account Tesla AI announced that Tesla is building a new generation of autonomous driving based on intelligent driving of a single basic video network, which will be able to drive vehicles directly.

At the same time as the above news was released, Tesla AI also started the recruitment for engineers, and said that it would create "the best end-to-end model based on large-scale fleet data". According to the recruitment information, the AI engineers recruited by Tesla are mainly oriented to basic model and Generative Modeling.

Although Tesla has not announced the specific direction of the next generation of autonomous driving, from the above information, Tesla will build the next generation of autonomous driving through the thinking and methods of large models based on the large amount of data and large-scale computing infrastructure it has-but at present, this exploration direction is still in its early stage.

9. Weilai officially released the self-developed intelligent driving chip Shenji NX9031.

On December 23, 2023, at NIO Day 2023, Weilai officially released the executive flagship car ET9 with a pre-sale price of 800,000, and released the first self-developed intelligent driving chip Shenji NX9031.

Specifically, Shenji NX9031 is the industry’s first intelligent driving chip manufactured by 5 nm gauge technology, with more than 50 billion transistors. Through the self-developed reasoning acceleration unit NPU, it can flexibly and efficiently run various AI algorithms such as BEV and Transformer. Wei Lai said that the efficiency of Shenji NX9031 in typical algorithms is much higher than that of existing benchmark products.

It is worth mentioning that with the release of Shenji NX9031, Weilai became the first OEM in China automobile industry to publicly announce its own intelligent driving chip.

10. Major players have promoted the landing of NOA in the city at the end of the year.

In December, new car companies, including Wei Xiaoli, are rapidly promoting the landing of urban navigation-assisted driving function.

Among them, on December 10th, LI released OTA 5.0. In terms of intelligent driving, full-scene intelligent driving will cover all expressways and urban loops in China, as well as urban roads in 110 cities. The safety of full-scene intelligent driving in high-speed scenes has also been upgraded. In the face of dangerous construction scenes, special-shaped work vehicles or extreme traffic jams, it can be bypassed or avoided in time to ensure driving safety.

On December 28th, Xpeng Motors officially launched a brand-new system version Xmart OS 4.5.0 for users such as G9, G6 and P7i. Along with this push, Xpeng Motors has also completed the layout and application of navigation-assisted driving function in 52 cities nationwide. At the same time, this OTA has greatly improved the ability of high-speed NGP, LCC and SR perception, taking into account the speed and depth of intelligent driving evolution.

Also on December 28th, Ren Shaoqing, vice president of Weilai Intelligent Driving R&D, announced that Weilai Global Navigation Assistant NOP+ had opened a total of 319,821 kilometers of urban mileage, refreshing the previously announced goal of "completing the verification of 250,000 kilometers of urban navigation route by the end of the year". By December 28th, there were 74 new cities in Weilai where the roads were connected into a network, with a total of 208.

It is worth mentioning that, at the M9 press conference on December 26th, Yu Chengdong said that high-level intelligent driving that can be started all over the country will also be used by users in OTA one after another before the end of December.

Write it at the end

Looking at the development process of the entire intelligent driving industry in 2023, we will find that the development of the intelligent driving industry has actually reached a key node.

From the perspective of business, intelligent driving, as the core component of automobile intelligence, has landed on more and more mass-produced models, and the performance of intelligent driving has gradually improved in the user’s car purchase decision. At the same time, consumers’ perception and acceptance of intelligent driving is getting higher and higher; Even from the perspective of high-speed pilot-assisted driving, intelligent driving has shown a downward trend in high-speed scenes.

However, from a technical point of view, the development of the entire intelligent driving technology route is far from mature; Especially in the aspect of urban navigation-assisted driving, the development of technical framework has entered a certain platform period, and the ability of engineering landing has become the focus. With the development of AI technology and the emergence of large models, players like Tesla are also trying to explore new possibilities of autonomous driving in technical paradigm.

One is downward popularization, and the other is downward exploration-but there is no contradiction between them.

From a longer period of time, intelligent driving is still a long track, but there will be more and more players in this track and the competition will become fierce. But at the same time, it is in this fierce competition that intelligent driving has the opportunity to achieve step-by-step progress from various levels such as technology, engineering and commercial landing, and ultimately benefit more ordinary consumers.

Therefore, 2023 is coming to an end, but smart driving will continue to move forward, and it may be more magnificent and changeable in 2024-and we will keep looking forward to it.

Qin L, the brand-new mid-level car of BYD Dynasty, finally shows its true features, and the dragon’s face has evolved, which is amazing!

The overall style of Qin L is inherited from BYD Dynasty’s "aesthetics of the new country’s tide and beauty", and the whole vehicle is elegant in atmosphere and fashionable in technology. The ingenious fusion of oriental verve makes Qin L look elegant and calm, showing the beauty of relaxation and balance.

According to the information of the Ministry of Industry and Information Technology, the length, width and height of Qin L are 4830x1900x1495mm respectively, and the wheelbase is 2790 mm. It is foreseeable that the seating space in the car will be very spacious, which complements the elegant and atmospheric appearance.

Qin l’s front face has evolved again, which is somewhat similar to the style of the flagship model of the dynasty, "Han". The design is spacious and stylish, and it is not angry and arrogant. The body color matching of Bingpoqing is very textured, inspired by Jingdezhen’s unique celadon, and the elegance of celadon is in harmony with the power of the dragon god.

In detail, the long, narrow and sharp LED headlight group is highly integrated with the 3D "dragon beard", and the dragon beard is very recognizable; The "Longkou" below is domineering and open, and the front grille is evenly spread like a dragon scale, which is full of momentum; The design of the fog light area below is also unique. The large opening not only enhances the visual impact, but also makes the front face more exquisite.

The side of Qin L adopts a slip-back design, showing a "wide-body, low-lying" posture, such as a dragon that is ready to go. The airflow can pass smoothly along the curve of the top of the car body, reducing turbulence and wind resistance, with both face value and performance; The waistline runs from the front fender to the back door, which makes the car more slender. With the concave rib line under the door, it creates a three-dimensional cutting effect and highlights the strength of the whole car.

At the rear of the car, the ultra-wide back shoulder surrounds the design, which not only echoes the front face, but also increases the muscular feeling of the body contour; Through taillight modeling, inspired by Chinese knots, full of recognition; The slightly warped small tail design is also the crowning touch, adding a bit of sporty atmosphere to Qin L. In addition, Qin L is also equipped with double five-spoke sports wheels, which are sharp, moving in silence, and showing the beauty of balance between movement and static.

There is no doubt that Qin L’s face value belongs to the first echelon of the mid-level car market, which caters to the aesthetic trend that young people love and pursue the national tide.

The arrival of Qin L and Qin PLUS will form a "big and small Qin" combination, with a larger size and higher level positioning, seize the mid-level car market represented by Camry and consolidate BYD’s position in the car market. In terms of price, the starting price may exceed 120,000 yuan.

　　[car home new car listed] Chery (|) officially listed today.The new car launched three models with a price of 159,900-179,900 yuan.The car will be equipped with a plug-in hybrid system consisting of a 1.5T engine and an electric motor, and the fuel consumption of WLTC is 1.70L/100km.

■ New car features

　　In terms of appearance, the new car is consistent with the fuel version, and a blue decoration is added at the bottom of the grille to indicate identity. Specifically, it adopts a large-size front air intake grille and is equipped with a lattice-type middle net structure, which looks very atmospheric.

　　On the side of the car body, the new car adopts the standard SUV body structure, and the front and rear fenders slightly protrude from the car body, showing the fashionable and dynamic side of the car. In terms of body size, the length, width and height of the new car are 4745/1860/1747mm and the wheelbase is 2710mm respectively.

　　On the tail side, the new car is equipped with a roof spoiler, and the taillights adopt a through design, and the array shape of the internal light group is highly recognizable after lighting. In addition, the new car also adopts a bilateral chrome-plated exhaust design, which surrounds the rear diffuser decorative panel in the middle to further enhance the dynamic effect of the vehicle.

■ Edit comments

　　The Tiggo 8 PRO is the third model of the Tiggo 8 family. It is the same as the two brothers in the series in three parts and body size, but it has changed its appearance, interior and configuration. Compared with Tiggo 8, which focuses on economy and practicality, Tiggo 8 PLUS focuses on luxury, while Tiggo 8 PRO focuses on youth and technology. It is aimed at the post-90 s family, which not only inherits the advantages of the large space of Tiggo 8 series to meet household needs, but also meets the needs of intelligent networking and young design after 90 s. In the current rush of new energy vehicles, the introduction of the plug-in version of its fist products can further enrich the power combination of the models and meet the needs of more consumers. I also hope that Tiggo 8 PRO new energy will be successful after listing. (Text/car home Xing Yueyang)
