The century puzzle left by Einstein and Bohr to future generations

In the early days of the establishment of quantum mechanics, the phenomenon of "entanglement" aroused the curiosity of all physicists, and Einstein called it "strange interaction between distant places."The so-called entanglement in quantum mechanics is a phenomenon: two particles in an entangled state can maintain a special correlation state, and the state of both particles is unknown, but as long as one particle is measured, the state of the other particle can be known immediately, even if they are far apart.. In the past half century, the essence behind this phenomenon has been deeply puzzling scientists.

In the last century, the views on entanglement divided physicists into two factions: the Copenhagen school, represented by Bohr, believed that the so-called "reality" was meaningful only when it was connected with observation methods; But scientists such as Einstein can’t accept this view. They think that quantum mechanics is incomplete, and the measurement result must be predetermined by some kind of "hidden variable", but we can’t detect it. In 1935, Einstein, Podolsky and Rosen published an article entitled Can Quantum Mechanics Description of Physical Reality Be Considered Complete, demonstrating the incompleteness of quantum mechanics. Usually, people call their argument EPR Paradox or Einstein Localized Realism.

Bohr and Einstein argued about this for 50 years, and the problem was not solved until their final death, which has always attracted future generations to verify it.

How to verify it?

mentionLocalized realismIn fact, it contains two meanings:First, physical realism.Any observable physical quantity must exist objectively in a definite way, and if there is no external disturbance, the observable physical quantity should have a definite value;Second, localized causality.If the four-dimensional space-time between two events is space-like, there is no causal relationship between the two events. Based on this understanding, in 1964, the Irish physicist Bell put forward the famous "Bell Inequality", which established a strict limit on the possible correlation degree of the results when two separated particles were measured at the same time [1]. If Bell inequality is not established in the experiment, it means that the expectation based on localized realism does not conform to the theory of quantum mechanics, that is,The quantum world itself is probabilistic.

All along, people have designed various experimental schemes to verify whether Bell’s inequality is correct or not, and one after another, the results of some experimental groups tend to support the destruction of Bell’s inequality-that is, to prove the correctness of quantum mechanics. The first truly definitive experiment was made by Spector, a French physicist. Three experiments they made in the 1970s gave a clear conclusion about the nonlocality of quantum mechanics, but there were still loopholes in the initial verification of these experiments. In recent years, experimental groups in different countries have tried to gradually close local vulnerabilities, free choice vulnerabilities and detection efficiency vulnerabilities in their experiments.All the experimental results support the conclusion of quantum mechanics and prove that localized realism is wrong.

Bell inequality goes out of the laboratory and flies further.

The destruction of Bell inequality has been verified in the laboratory, so what about the situation on a larger scale? If people can verify the existence of quantum entanglement at a longer distance, it means verifying the correctness of quantum mechanics at a larger spatial scale. Therefore, people want to fly farther with Bell inequality. However, there is a stumbling block-attenuation when conducting experiments on a larger scale. What does this mean? In the actual experimentPeople often use an experiment called "quantum entanglement distribution" to verify Bell inequality, which is to send two prepared entangled particles (usually photons) to two points far apart, and to verify whether quantum mechanics and localized realism are right or wrong by observing whether the measurement results of the two points conform to Bell inequality.Because pairs of single photons are prepared and sent, the signal of single photon is not amplified because of the non-replicability of quantum, and the inherent photon loss of optical fiber makes it difficult to expand the optical quantum transmission to a longer distance. On the surface of the earth, the quantum entanglement distribution of 100 kilometers is almost the limit.

What should we do? There are two schemes,One is to use quantum relay.One relay station is a bit like an ancient relay station, transmitting photons one by one, but at present, the research of quantum relay is still limited by the time and efficiency of quantum storage;Another scheme is to realize quantum entanglement distribution by satellite.The vacuum environment in outer space has almost no attenuation and decoherence effects on light transmission. The free space channel loss between the satellite and the earth is small, and even in theory, scientists can establish a quantum channel between any two points on the earth by using satellites, and it is possible to realize quantum entanglement distribution at a long distance on a global scale.

On December 9, 2016, at the Ali Observatory in Tibet, researchers were doing experiments.

Fortunately, in this respect, Chinese is at the forefront of the world.

As early as 2003, China’s Pan Jianwei team put forward a scheme to realize long-distance quantum entanglement distribution by satellite, and started preliminary verification. The team’s researchers believe that in order to prove that it is feasible for satellites to realize quantum entanglement distribution, it is necessary to prove that photons can remain coherent after penetrating the atmosphere, so they began to do experiments in Dashu Mountain, Hefei. In this experiment, the sender is in Dashu Mountain, and the two receiving points are in Feixi farmer’s home and the west campus of Chinese University of Science and Technology, which are several kilometers away. It is the first time in the world to realize the two-way quantum entanglement distribution in free space with a horizontal distance of 13 kilometers (the vertical thickness of the atmosphere is about 5-10 kilometers), which proves that the entangled state can still "survive" after long-distance atmospheric channel transmission. On the other hand, this transmission distance exceeds the equivalent thickness of the atmosphere, which proves the feasibility of long-distance free space quantum communication.

Two-way quantum entanglement distribution in free space with a horizontal distance of 13 kilometers in 2005

In 2010, the team realized the 16 km quantum teleportation based on quantum entanglement distribution for the first time in the world. Based on the preliminary key technical preparations, at the end of 2011, the strategic pilot science and technology project "Quantum Science Experimental Satellite" of Chinese Academy of Sciences was formally established. In 2012, the joint research team of Chinese Academy of Sciences led by Pan Jianwei realized the first quantum entanglement distribution experiment of more than 102km in Qinghai Lake. In the experiment, the maximum attenuation is 80dB. On the one hand, it is verified that the entanglement characteristics still survive through the atmospheric channel on a larger scale, on the other hand, it is verified that the entanglement characteristics can be maintained under the condition of very large attenuation, which further verifies the feasibility of satellite-ground entanglement distribution.

In the following years, the team worked hard to overcome various difficulties and finally developed the "Mozi" quantum science experimental satellite. In the eyes of hundreds of millions of people, the Mozi was successfully put into orbit on August 16, 2016. After four months of on-orbit testing, it was officially delivered to carry out scientific experiments on January 18, 2017.

Mozi quantum science experimental satellite

As one of the three scientific experimental tasks of Mozi satellite, satellite-ground quantum entanglement distribution is the first quantum entanglement distribution experiment on the spatial scale in the world.

There are three optical payloads on the Mozi quantum science experimental satellite. Pairs of entangled photons are prepared by the quantum entangled light source and sent by two optical antennas. When the satellite transits the border, two telescopes point to Delingha and Lijiang ground stations respectively. The receiving systems of the two ground stations, according to the angular velocity of the satellite, make the satellite establish quantum channels with the two ground stations at the same time and send entangled photons to the ground stations.Then the ground station carries out entanglement measurement of photons, and if there are enough statistics, the Bell inequality can be verified.

In this experiment, the distance between the two ground stations is 1200 kilometers, the total distance from the satellite to the two ground stations is 2000 kilometers on average, the tracking accuracy of the ground station reaches 0.4 urad, and the receiving efficiency of the ground station system is more than 20%. The entanglement source on the satellite can generate 8 million entangled photon pairs per second, and the establishment of optical link can establish quantum entanglement between two stations over 1200 kilometers on the ground at the speed of 1 pair per second, so that a large number of statistical data can be obtained in a short time. If photons are transmitted by optical fiber over such a long distance, even if ultra-low loss optical fiber is selected, it will take 30 thousand years to distribute a pair of photons.

In the experiment, the two photons are pulled apart by a large enough distance, and at the same time, the high-precision experimental technology ensures that the independent measurement time interval between the two places is small enough, which meets the measurement requirements of "space-like interval" in Bell inequality measurement and closes the localization vulnerability and measurement selection vulnerability.The experimental results show that the standard deviation of 4 times violates Bell inequality, that is, the correctness of quantum mechanics is verified at a distance of thousands of kilometers with a confidence of over 99.9%.The nonlocality test of quantum mechanics which strictly satisfies Einstein’s localization condition is realized. This important achievement has laid a reliable technical foundation for the future experimental study of large-scale quantum networks and quantum communication, as well as the experimental examination of the basic principles of physics such as general relativity and quantum gravity in outer space.

Related achievements were published in the international authoritative academic journal Science in the form of cover papers.. In addition to the quantum entanglement distribution experiment, other important scientific experimental tasks of Mozi quantum science experimental satellite, including high-speed satellite-ground quantum key distribution, satellite-ground quantum teleportation and so on, are also under intense and smooth progress. It is expected that more scientific achievements will be released to the public one after another this year.

On November 28, 2016, at the Xinglong Observatory in Hebei Province, the "Mozi" quantum science experimental satellite transited.

Note:

[1]Bell inequality has many famous generalizations. Considering the practical factors of the experiment, five years after Bell inequality was put forward, John Clauser, Michael Horne, Abner Shimony and Richard A. Holt put forward a CHSH inequality, and the experiment of Bell inequality in later experiments was mainly to verify CHSH inequality.

[2] Space-like separation means that the space-time interval of two events satisfies that "it is impossible to communicate between two events with information below the speed of light.

　　On November 1st, the international version of Xingtu officially ushered in the market, and the price range of the new car was 228,900-238,900 yuan, with three versions. The new car will continue to be equipped with a 2.0T engine +8AT transmission, with a maximum torque of 400 N m.. Today, we will test drive this model and feel what upgrades and changes have been made in the international version of Starway Moon.

　　In terms of appearance, Starway Moon International Edition still adopts the family-style design style, but it has changed in some details. The biggest change is the use of a brand-new octagonal air intake grille with horizontal decorative strips, which looks domineering enough.

　　The light group adopts a penetrating design. When the lights are turned on at night, the middle light band will be lit. The position of the eyebrows of the headlights uses a blackened design, which also reflects the personalization of the car. In addition, chrome-plated decorative strips are added to the air inlets on both sides of the front bumper, which adds a lot of fashion to the car.

　　The shape change of the side of the car body is not great, and the through waistline design is still used, and the traditional door handle shape is retained, so the use convenience is still very high. In terms of body size, the length, width and height of the new car are 4970x1940x1792mm and the wheelbase is 2900mm respectively.

　　The shape of the rear end of the international version of Starway Moon Tour has not changed much, and the design of the through taillight group is still retained, which effectively increases the layering of the rear end. The rear bumper is decorated with a chrome trim strip, and equipped with a double exhaust layout, and the vertical reflectors on both sides are also preserved.

　　There is no change in the design of the interior, mainly reflected in some details, such as the addition of all-black color matching, which also provides consumers with more choices. In addition, the dual wireless charging panel of the new car is also decorated with suede, and the maximum power can reach 50W.

　　Although it is a fuel SUV, the car uses a two-spoke steering wheel, with bronze decoration and multi-function touch panel, as well as a panel with a sense of space, which enhances the luxury of the whole interior. Shift paddles are also reserved on the steering wheel, which can effectively improve the driving pleasure of the vehicle.

　　The international version of "Journey to the Moon" retains the penetrating triple screen design, and the 12.3-inch LCD instrument panel can display a lot of driving information of vehicles, including speed, driving mode, speed, entertainment information, navigation information, cruising range, etc., and the display clarity is still very high.

　　HUD head-up display is also very easy to use. When navigation is not turned on, HUD can display information such as vehicle speed and rotation speed. When navigation is turned on, HUD can display navigation information, including text and dynamic images, with good clarity.

　　Lion5.0 lion system will be used in the central control screen. The UI design of the whole screen is very user-friendly, and the delamination application is in place. The commonly used functions can be found at the bottom of the screen. The screen can support online navigation, online entertainment, mobile phone interconnection, voice interaction, OTA upgrade and other functions, which can fully meet our daily use.

　　The intelligent driving system of the new car can also be selected and set on the screen, and the whole interface is easy to understand. In addition, the air conditioning, seats and other functions of the vehicle are also placed on the screen, which can be controlled by voice or from the screen, and the sense of technology is still very high.

　　The sliding cover is still reserved in the central channel. After opening, the wireless charging panel of the mobile phone below is made of suede, which looks more advanced and feels very good. The maximum power of the wireless charging panel of the mobile phone is 50W, and a cooling vent is designed at the lower position, so that the mobile phone will not generate heat even if it is charged for a long time.

　　A small touch panel is also designed in the rear position. Here, it integrates the control of one-button start of the vehicle, double flashing, air conditioning air volume adjustment, defogging of front and rear windows, internal and external circulation, etc. It needs to be familiar with it for the first time, but the overall luxury temperament is still very good.

　　The car we test-drive today is a 6-seat model of the international version of Starway Moon. The seat configuration of the car is also rich enough. The front seats are not only equipped with electric adjustment, but also have functions such as seat heating, ventilation, memory and massage. At the same time, there are speakers in the headrest, which is more clear and specific when playing music or broadcasting road conditions.

　　The second row uses two separate seats, which are also electrically adjustable. Although the distance of the slide rail is not very long, it can also meet the riding needs of passengers in the second row or even the third row. The comfort of the second row of seats is also relatively high, and even if you ride for a long time, you won’t feel tired.

　　The third row of seats also uses two independent seats, the softness of the seat cushion is also very good, not as thin as expected, and the head and leg space is acceptable. The backrest is also designed with 5/5 points, all of which are manually adjusted, and the support of the backrest is average.

　　There is no change in the power of the international version of the Star Way Lunar Rover, and it is still consistent with the current models on sale. It uses a 2.0T engine with a maximum power of 261 HP and a maximum torque of 400N·m, which is matched with an 8AT transmission.

　　When we put this car on the road, the first thing that impressed us was not how strong the power was, but the suspension adjustment of this car. As a 6-seater /7-seater model, the suspension adjustment of the international version of Starway Moon Landing is soft, which can also handle the bumps on the road well and increase the comfort of the members in the car.

　　On the other hand, in terms of power, the new car is also equipped with a four-wheel drive system, so even in the economy and comfort mode, the power performance is relatively good, and the response time of the accelerator pedal is relatively fast. When we switch to the sport mode, the speed of the vehicle when shifting gears has changed obviously, and the feeling of shifting gears is also more obvious. Together with the use of shifting paddles, it also increases the driving pleasure of the vehicle to the greatest extent.

　　In terms of quietness, when the vehicle is driving at 80km/h, the control of wind noise and tire noise is very in place. However, when the vehicle speed is raised above 100km/h, the wind noise will increase obviously, but it is within the acceptable range. The tire noise and chassis performance are still excellent, and there is no sound coming out.

　　In terms of handling, although the car is large in size, the steering wheel is very flexible, even continuous line changing or one-handed operation can be easily completed. When turning around in a corner, the turning radius of the vehicle is quite satisfactory, but fortunately, the body is higher and it can have a better view.

　　The intelligent driving performance of the new car is also satisfactory, including ACC adaptive cruise, lane departure warning, rear car reminder and other functions are very easy to use, which also greatly relieves our fatigue when driving at high speed, and also improves the safety of the vehicle to a certain extent.

　　Summary:

　　As an SUV model for home use, Starway Moon International Edition has achieved the leading level of the same price in terms of appearance, interior technology, interior materials, intelligent driving performance and space. After all, the price range of this car is 22.89-23.89 million yuan, so it still has strong market competitiveness. So as a dad, will you consider this medium and large SUV?

　　1. At the same price, there are more imported cars than 4S shops.

　　2, the same configuration, imported cars are cheaper than 4S stores.

　　3. The quality of imported cars is better than that of 4S shops.

　　4, all models are bare car prices, our company does not force any other fees (insurance, decoration).

　　Disclaimer: The above car purchase preferential information is provided by the comprehensive dealers of this website, and the price fluctuates greatly due to market factors, which is only for car purchase reference; The distributor is responsible for its authenticity, accuracy and legality, and this website does not provide any guarantee or assume any legal responsibility.

　　As major car companies continue to enrich the product layout of their electric vehicles, more and more car scenes have been overcome by electric vehicle products. In the past, many consumers who insisted on choosing fuel car products because of mileage anxiety, lack of driving pleasure and few options have changed their views.

　　However, it can’t be ignored that there are still a large number of consumers whose demand for cars is not limited to urban transportation. They need a car product with the functions of commuting to work and family travel during holidays. More importantly, when they swim between mountains and rivers, they don’t want to worry about finding charging piles for their cars. Then, an SUV model with exquisite shape, comfortable space, abundant power and strong off-road genes has become their first choice for car purchase. Today, the protagonist of our test drive-2024 big dog is such a product.

1. The air intake grille of the new car adopts a brand-new standard, which is more powerful with the shield-shaped middle net; The rear of the car is equipped with penetrating taillights, and the integrated design has a more holistic feeling.

2.The interior is still outstanding in science and technology, and covered with more soft materials, with fine workmanship and better touch.

3. The adjustment of the new powertrain is relatively mature, the power reserve of the 2.0T engine is strong, and the 7DCT is upgraded to 9DCT, further improving the fuel economy of the vehicle.

4. Two terrain modes (grass/gravel, concave-convex road) are added to the new model, which further improves the passability and safety and increases the driving pleasure.

　　Before officially introducing the new car, let’s briefly sort out the relationship between the new car and the big dog models currently on sale. At present, there are two generations of big dog products on the market, one is based on the annual modified model of the first generation of big dog models listed in September 2020; In addition, it is the first model listed in February this year. Although the latter is also named after the "big dog" element, the new car has adopted a new design from appearance to interior, and its size is also larger, reaching the level of medium-sized SUV. Today, the 2024 Haval Big Dog that we test drive is the latest modified model of the original Haval Big Dog.

　　The 2024 big dog basically continues the design style of the old models, which first gives people a sense of sight full of strength and wildness, and at the same time emphasizes the exquisite and fashionable design fashion through the changes of details. The front face of the 2024 big dog still adopts a relatively square outline, and the new car net has undergone a new design, showing a shield shape, which makes the new car look a little more stable and more tenacious from the front.

　　The new car headlights still use the "Eye of the Earth" round LED headlights, which are retro and highly recognizable. The outer contour of the headlight is integrated with the middle net, and the middle net is decorated with two rough horizontal silver chrome trim strips, which effectively stretches the visual width of the front of the car. The size of the brand LOGO has been increased, and the black design is adopted, which is embedded in the side trim on the middle net, which not only forms a more concise effect, but also does not lose the sense of strength.

　　The side of the new car shows the image of a typical hard-core SUV. Although the fixed side pedal is cancelled, the straight roof line, the black decorative board on the lower edge of the side door and the rounded trapezoidal wheel eyebrows like the earth fortress all imply its powerful off-road performance. The tire comes from Jiatong brand, the specification is 235/65 R18, which has both the quietness of urban driving and good off-road ability.

　　The change of new car tail is very obvious. There is no doubt that penetrating taillights are the current fashion trend. When applied to 2024 big dog models, it effectively adds a bit of luxury to this hard-core SUV. At the same time, this design also visually extends the width of the tail, echoing the front of the car.

　　There is not much innovation in the black rear bumper and the silver lower fender, but in addition to emphasizing the off-road attribute from the perception, thanks to the departure angle of 30 of the new car, the 2024 Haval Big Dog is more calm in the face of bad roads.

　　The interior of the 2024 Haval Dog maintains the same style as the old model. Two large-size LCD screens create a strong sense of science and technology in some areas, which is in sharp contrast with the armrest in front of the co-pilot who highlights the hard-core atmosphere, resulting in a kind of confrontational beauty. The center console of the new car is still made of a large number of hard plastic materials. Of course, this is understandable for a hard-core SUV that emphasizes functionality. The material of the auxiliary instrument panel of the old model is easy to leave fingerprints, and the new model has been upgraded to help keep it clean. At the same time, the center console of the new car also adopts the stitching design of stitching technology, which looks very classy.

　　It is worth mentioning that the engineers of the 2024 Haval Dog did not blindly control the cost, but effectively optimized the design method. This optimization is reflected in the fact that in addition to the leather elements used in the steering wheel and seat, the inner side of the door panel that drivers and passengers contact most often is also covered with soft materials, which makes it feel better.

　　The steering wheel of the new car has a moderate size and comfortable grip, and the multi-function button area adopts a bright black panel, which makes the physical buttons easy to operate and has a good texture.

　　The function area of the center console is designed with touch and physical buttons, which takes into account consumers with different operating habits. From the experience effect, the touch screen interface runs smoothly and the feedback is timely; Physical keys and driving mode switch knob have moderate damping and easy operation. Personally, if there is a need for functional operation during driving, physical buttons are conducive to more accurate control and more conducive to ensuring driving safety.

　　There are not many changes in the functional configuration of the 2024 Haval Dog. In fact, the models mentioned in the preceding paragraph have been perfected in this respect, such as the exterior rearview mirror with three-in-one functions of driving mode memory, heating, automatic folding and lighting, constant temperature three-zone air conditioner equipped with air purification system, and large-size panoramic sunroof.

　　What is impressive is the 360-degree panoramic image+transparent vehicle bottom function. Four wide-angle cameras are used to collect images of the environment around the vehicle, reducing the blind spots around the vehicle, enabling users to grasp the images around the vehicle in real time and improving the driving safety of the vehicle. The transparent chassis eliminates the blind area of vision through camera technology, provides the driver with the road conditions under the car, and helps the driver to see the safety hazards on the road through the display screen. The puddles and stones under the car can be cast on the screen to avoid them in time.

　　In addition, it can be seen that as an SUV model that pays attention to off-road performance, the 2024 Haval Big Dog rear axle electronically controlled mechanical jaw differential lock supports independent physical key control, realizing human-computer interaction and increasing driving pleasure; Mechanical jaw locking can realize 100% output of torque between wheels on both sides of the rear axle, and has stronger ability to get out of trouble.

　　Although the width of the seat with electric adjustment function is not large, the advantage lies in solid filling and proper support. Leather coating and stitching technology not only make the ride comfortable, but also show great grades visually. In terms of driving space, the 180CM experiencer has a punch space in his head after adjusting the seat to the appropriate position in the driver’s seat; Keeping the seat position unchanged, the experiencer also has the head space of one punch in the back row, and the leg space is close to three punches. This performance will not make passengers feel depressed even if the road is far away.

　　The 2024 Haval Big Dog continues its rich storage space. According to official information, there are as many as 37 storage spaces in the whole car, which is at the upstream level in the SUV of the same level. From the actual experience, it is more than enough to put down two bottles of 550ML drinking water in a conventional glove box, a layered central armrest box and a door panel storage compartment. The storage space under the central passage and the separate water cup holder on the door panel are not only decorative, but also convenient to use.

　　This time, my test drive vehicle adopts the powertrain of 2.0T engine +9DCT gearbox, and is equipped with intelligent four-wheel drive system. This 2.0T engine (GW4N20A) has a maximum power of 175kW and a maximum torque of 385 N m. The transmission system has been upgraded obviously, and the 7DCT gearbox used in the previous model has been replaced by the self-developed 9DCT gearbox. A more compact speed ratio will help to improve the smoothness and comfort of shifting, as well as the low-speed power and high-speed economy.

　　Driving: driving in the city is safe, and long-distance cross-country is more fun to control.

　　Although this 2.0T engine has a good book strength, we can clearly feel its pursuit of comfort in actual driving. The accelerator pedal feedback of a new car is definitely not sensitive. At the beginning of the pedal stroke, it corresponds to a linear power output, and the momentum is not obvious, and the shift process is also very smooth. If you want to get a simple sense of acceleration in the initial stage, don’t hesitate to step on the accelerator pedal deeply. The powerful power reserve will be output violently when the accelerator pedal stroke is close to about one third.

　　With the increase of vehicle speed, the power supply of new cars becomes more abundant, which also brings full confidence to drivers in overtaking at high speed. At this point, the throttle feedback is also positive, which can be said to be on call. At the same time, it is not difficult to find that thanks to the wider gear ratio of the gearbox, under the same speed, the speed of the 2024 Haval Big Dog is lower than that of the previous model, which undoubtedly helps to improve the fuel economy of the vehicle.

　　However, it should be noted that the steering system of the new car needs to be adapted more, especially in the middle and high speed range, and it can be clearly felt that there is a certain virtual amount in the steering wheel. If the comfort of passengers in the car is to be guaranteed, the timing of braking should be grasped before entering the corner, and the speed should be lowered as soon as possible. Of course, this is not to say that the bending safety is insufficient, but to avoid giving passengers the feeling that the lateral support is too soft.

　　As another important upgrade of the 2024 Haval Big Dog, the new car has added two terrain modes: bumpy road, grass/gravel, based on the driving modes of economy, standard, sports, mud, sand and snow. As we all know, bumpy roads make it difficult for vehicles to pass. The all-terrain control system of 2024 Haval Dog will control the slip of the vehicle through the vehicle stability system control unit and differential lock to improve the passing ability of the vehicle.

　　In this test drive, we actually experienced the grass road conditions. Usually, vehicles are easy to slip in this scene, and the stability and passability are poor. With the blessing of the all-terrain system, the 2024 Haval Big Dog can easily drive on the wet grass by controlling the entire chassis electronic control system of the vehicle.

　　In addition to the further subdivision of driving mode, the 2024 big dog can perform well in this unpaved road condition thanks to the intelligent four-wheel drive system adopted. In AUTO mode, the electronically controlled hydraulic active control system distributes the torque of the front and rear axles more quickly, accurately and smoothly. In the face of complex and changeable road conditions, the intelligent and dynamic torque distribution characteristics respond instantaneously with the change of vehicle working conditions, which greatly improves the driving comfort and flexibility of vehicles.

　　Summary: Since its launch in 2020, Haval Dog, as a online celebrity model in China SUV market, has become a travel companion for more than 300,000 car users. Although the appearance of the 2024 Haval Big Dog has not changed much, it has brought obvious texture upgrade. The interior is still outstanding in science and technology, and the addition of some soft materials better guarantees the driving comfort. The adjustment of the new powertrain is relatively mature, the power reserve of the 2.0T engine is strong, the 7DCT is upgraded to 9DCT, and the denser gear ratio obviously improves the smoothness of shifting. The newly added driving mode also performed well, further optimizing the passing capacity of the new car under complex working conditions.

　　It is understood that 2024 big dogs will be listed in the near future. In addition to the 2.0T+9DCT model we have tested this time, we will also launch a model equipped with a 1.5GDIT engine (GW4B15L)+7DCT transmission power combination. The maximum power of the 1.5T engine is 135kW, and the peak torque of generate is 275N·m at 1500rpm. The comprehensive transmission efficiency of 7DCT transmission reaches 95.6%, reaching the functional safety level of ASIL-C system. Combined with the pricing strategy of current models, I believe that the 2024 Haval Big Dog will once again enhance its cost-effective advantage and take the lead in the cruel market game.

　　Financial Investment News reporter Xue Lei

　　Musk’s visit to China was broadcast on the news network, and was paid attention to together with FSD (fully automatic driving) technology. As for other joint purposes, it is said that we want to seek the further landing of FSD technology in China market. However, although "Musk’s visit to China" can be broadcast on the news, "Tesla’s FSD technology landed in China" is very difficult.

　　First of all, the problem of data security lies ahead. China’s autonomous driving supervision policy is quite strict, especially in data security and privacy protection. Most of Tesla’s databases are abroad, and Chinese laws clearly stipulate that all user data must be stored in China, which means Tesla must establish and maintain a data center in China. This not only involves huge investment, but also needs to ensure that the technological advancements of these centers are consistent with those of other data centers around the world, and at the same time meet China’s requirements for data security.

　　If Tesla’s FSD technology needs to transmit data overseas, such as global data analysis or using global servers, there are many regulations to be observed during this period, such as what can and can’t be transmitted, and what approval procedures are required to transmit data. There are many problems to pay attention to, and there are many processes to go.

　　The second is the problem of technical adaptation. China’s technical standards in the field of smart cars are different from those in the world. Tesla needs to adapt FSD technology to the road conditions, traffic rules and driving habits in China, which means a series of adjustments are needed. The road traffic environment in China is complex and changeable, which puts forward higher requirements for the adaptability and reliability of FSD technology.

　　Although Tesla has many loyal fans in China, many people still hold a wait-and-see attitude towards FSD technology. Besides, the smart car market in China is booming, and local enterprises have invested heavily in autonomous driving technology, and they have a deeper understanding of the local market. It is not easy for Tesla to gain a share in the China market, except to overcome technical problems, but also to find its own foothold in the fierce market competition.

　　 FSD technology itself is a "golden cave", and research and development, testing and deployment of fully automatic driving technology require a lot of capital investment. In order to enter the China market, Tesla also needs to establish a corresponding service and support system in the China market, which also requires a lot of money and resources. Of course, there is no shortage of money to deploy Musk in the early stage, but how to make a profit in the later stage? A few days ago, Tesla launched the EAP subscription service, which costs as much as 699 yuan per month. This price is unique among domestic car companies and has no competitive advantage at all.

　　For China car companies, Tesla’s FSD technology is not terrible. In China’s electric vehicle market, domestic car companies have too many advantages, and Tesla needs to complete localization, but domestic car companies are old aborigines, which is an inherent advantage. For domestic car companies at this stage, Tesla only acts as a "catfish". Regardless of whether they finally enter the market or not, the FSD technical duel of domestic car companies has begun. However, with the passage of time, this uncertainty will become greater. After the embarrassing period of Tesla’s localization, the good play will begin.

The official propaganda is 400km. Actually, it’s about 360-370km once tried, and it’s a little worse in winter, almost the same as the official propaganda. Anyway, I’m going to charge it when I have about 100 left, and it’s charging quickly. Accuracy of battery life: the battery life is relatively accurate. It has been running for more than 3,000 kilometers by car. In most urban areas, the power consumption is about 16kw per 100 kilometers, which is not bad. In terms of energy consumption, the advantages of new energy sources are not highlighted!

For a girl like me, the space can be described as spacious. Haha, I am 165 in height and 120 kg in weight. Sitting in the car, no matter my head or legs, there is enough room for activities, and I don’t feel narrow at all, because I will take a few girlfriends out to drink milk tea and go shopping on holidays. They also praised me that this car doesn’t look big. In fact, it is quite spacious when sitting. If you are motivated, if you don’t pursue accelerated passion, its performance is still quite awesome. When waiting for the traffic lights, it is often faster than the car next to it, and the acceleration is very smooth. It may be inferior to those fuel cars at high speed, but basically it can crush all kinds in the urban area. After all, it is an electric motor.

If you look at the appearance, you still have to look at your personal preference. I just prefer this cute style. The more you look at it, the better it looks. When you drive out beautifully, the whole person’s mood will be better. As for the car, it is mainly because you like it. This is the most important thing. The workmanship of the interior is still exquisite, especially the handling of some details, and the joints of the gaps are handled very delicately. It makes you feel that it is not cheap at all, and the materials are very kind, and most of them are covered with soft materials. The visual effect is awesome! Another place worth mentioning is that the intelligent system is really convenient to use and has all kinds of functions. Novices can also control it quickly.

A car with super high cost performance, I don’t think there is anything more worthwhile than it at the same price. If I choose it again, it will still be a good cat. It’s too convenient to reverse the car. Lateral reversing is the shortcoming of many girls. With this, I can easily get in and feel powerful again. Convenience of wireless charging of mobile phone: Although this wireless charging is a bit slow, it improves the convenience and sense of technology of a good cat. App remote control: the remote control is too powerful. In summer, it is set to cool down quickly for 5 minutes before work. How high the temperature is, it will be full of coolness. This is really friendly to the owner. I forgot to bring my key when I changed my bag, and I started the vehicle directly by APP Bluetooth unlocking, and there was no anxiety in an instant.

The steering accuracy of the steering wheel is quite high, which is called a smooth operation. The steering wheel is relatively light, but it won’t make people feel mad, and the steering accuracy is also very high, giving people a practical feeling. The brake is completely determined by the intensity of the individual’s foot stepping, which is easy to control and the design of the seat is very ergonomic. Sitting on it feels good, and the shock absorption is not too hard, so the filtering of road vibration is relatively complete, at least it won’t make you feel particularly bumpy. Although the sound insulation is not particularly perfect, at least when driving often, the people inside the car will not be affected.

This car has three shortcomings:

The first disadvantage is the price of this car. I didn’t give a discount when I bought it. I feel a little worse about the price/performance ratio, but who will like it? Book early, pick up the car early and enjoy it early.

Secondly, due to work reasons, I often drive this car to some places with uneven roads. I feel that if I take that bad road, the sense of bumps is still quite obvious.

Thirdly, I think its disadvantage is probably that the sound insulation effect is not very good. It feels ok if you run at a low speed in the urban area, but if the speed is faster, you can hear more obvious noise. I am very sensitive to hearing, so I feel the need to spit it out.

　　[car home second-hand through train] Looking at the domestic SUV market, tanks are definitely one of the hot brands. Both (|) and Tank 500 have created sales records that demand exceeds supply, and even used cars are more expensive than new ones. Nowadays, the tank 800 frequently exposes spy photos. I believe that it is not far from you to leave the "Baoding Cullinan". But today, are the tanks 300 and 500 still so popular? Is the used car still so valuable? Let’s take a look at this issue together.

　　Different from Tank 300 and Tank 500, Tank 800 will be the flagship product of the "business luxury" route of tanks, and its design ideas will be more luxurious and atmospheric.

　　From the latest spy photos, we can see that the state of this vehicle is very similar to the version exhibited at the previous 2021 Shanghai Auto Show. We guess that the new car is also likely to be a tank 800 model close to the production version.

　　The more luxurious and atmospheric design is quite eye-catching, but besides the tank 800, the tank 300 and the tank 500 also have a very high degree of attention. If you want to be a "tank driver" earlier. Let’s take a look at the current market of tank 300 and tank 500.

　　The new cars currently on sale for Tank 300 are mainly two off-road models and three urban models, and the official version of Tieqi 02, which cooperates with Dinghuo. The official guide price ranges from 198,800 yuan to 302,800 yuan. As a hard-core off-road vehicle, this price range is still relatively close to the people, which is one of the reasons for achieving considerable sales.

　　However, since the second half of last year, the production speed of tank 300 has increased. Up to now, it is basically possible to pick up a car in about one month, and the popularity of new cars and the market for used cars of tank 300 have gradually declined.

　　Take the 2023 Conqueror version, which is more popular in the used car market, as an example. The guide price of a new car is 215,800 yuan, and a quasi-new car that has been licensed for about one year can basically sell for about 200,000-210,000 yuan. For the old conquerors around 2021, the second-hand price of standard car condition is around 190,000 yuan.

　　The standard car condition mentioned here is the normal kilometers of the car. In fact, as a hard-core off-road vehicle, the second-hand tank 300 can be said to be a car in one condition, not only to distinguish whether there is a history of off-road, but also to distinguish whether there is a modification.

　　In addition to post-modification, Tank 300 has introduced some original modified versions, such as Cyber Tank Edition, Border Limited Edition, Wind Forest Fighter, Tank Ranger and so on. Due to the official modification and limited sales, the prices of second-hand quasi-new cars of these models are basically 20,000-30,000 yuan higher than when the new cars land. However, with the continuous introduction of limited edition models and the decline in the popularity of new cars, the second-hand market of such models has gradually dropped.

　　Comparing the market, we can see that the tank 300 has indeed gradually reduced the heat and market from the previous "used cars are more expensive than new cars". However, in the same class and at the same price, Tank 300 is still the car with the highest rate of preservation and heat.

　　When considering used cars, it is recommended to consider quasi-new cars with short age and few kilometers. Although the price/performance ratio is not as high as that of old used cars, the problems reflected by the owners have been solved in the late batch, with better quality and more worry-free later. In terms of color, except for "Bai Fumei" and "I want red", they are basically popular colors with high preservation rate.

　　After talking about tank 300, let’s take a look at its "big brother" tank 500. In the eyes of many friends, tank 500 and tank 300 are also the light of domestic products. What about the second-hand market of tank 500?

　　The new tank 500 cars are mainly divided into Dengfeng/Terrace, Sport/Business, 5-seat /7-seat models, as well as the original factory’s special customized version with double colors. The price range of the new car is 335,000-395,000 yuan. However, in contrast, the new car sales of Tank 500 are not as high as those of Tank 300, and the second-hand market is relatively stable.

　　Take the sports version of the 7-seat environmental model as an example. The guide price of the new car is 363,000 yuan, and the new car is about 400,000 yuan. One-year-old second-hand quasi-new car, basically the purchase price is only 300,000 yuan, the individual transaction price is about 310,000-320,000 yuan, and the one-year preservation rate is about 80%.

　　Also affecting the current market of tank 500 is the launch of new models, namely the Hi4-T plug-in hybrid model. Before Tank 500, there was a lot of controversy about fuel consumption, and the Hi4-T plug-in hybrid model can solve everyone’s concerns about fuel consumption to a certain extent. Naturally, fewer people choose the 3.0T version, and the second-hand market will only fall but not rise.

　　Summary:

　　No matter the tank 300, the tank 500 or the future tank 800, they are all the benchmark products of China brand SUV. After the production capacity of tank 300 and tank 500 increased and the popularity of new cars gradually decreased, the market conditions gradually returned to normal. As consumers, we need to keep a clear head and rationally choose the right model according to our own needs.
