Wuling Hongguang MINIEV is hot in the electric vehicle market, so can the car stand the "test" of high temperature in summer? Let’s take Wuling Hongguang MINIEV 2022 macaroon Zhenxiang Ferrous lithium phosphate as an example. Let’s take a look.

Test model: Wuling Hongguang MINIEV 2022 macaroon Zhenxiang Ferrous lithium phosphate.

Test temperature: 40 degrees to 49 degrees outdoors.

The maximum speed of this car is 100km/h, and during the speed test, the car starts relatively fast and accelerates to the rear, and it takes a long time to complete the journey from 50km/h to 100km/h, and the measured maximum speed of the car can reach 101.31km/h, which is basically consistent with the official results.

During the high-temperature continuous acceleration test, the test interval is 1 minute, and the acceleration lasts for 10 times. The shortest measured acceleration time of 100 kilometers is 21.84 seconds, and the motor performance is not obviously attenuated.

So what is the reliability performance of the battery at high temperature? The car is verified by high temperature endurance and fast charging ability. Before the high-temperature endurance test, the air conditioning temperature was set to 24 degrees, the automatic mode, the driving mode was adjusted to the economic mode, and the kinetic energy recovery was the strongest. The car completed the endurance test at an average speed of 80 km/h. Under the high-temperature and high-speed working conditions, the measured cruising range of this car was 113.6km/h, and the pure electric cruising range of the Ministry of Industry and Information Technology was 170km, with a cruising achievement rate of 66.8% and a high cruising achievement rate.

It is worth mentioning that the endurance test went to zero, and the tire pressure of the vehicle began to alarm. After the test, the measured tire pressure values were all normal, which was judged as accidental failure. At high temperature, the driving quality of the car performed well.

During the high-temperature charging test, the AC slow charging pile with power of 7kW was used. The high-temperature charging test of this Wuling Hongguang MINIEV was stable. It took 596 minutes to fully charge and charged 15.7kWh of electricity. There was no abnormality during the slow charging process, which was basically consistent with the official slow charging of 9 hours.

When parking in summer, exposure is indispensable. When Wuling Hongguang MINIEV is baked at a high temperature above 40 degrees for more than 2 hours, the temperature inside the car reaches about 56 degrees. In the area where the car is in direct contact with the human body, the average temperature reaches over 68 degrees. The hottest place inside the car is under the windshield, and the temperature is 82.5 degrees. This car is equipped with a fabric seat, which is not as hot as a leather seat, and the glass is isolated from ultraviolet rays and infrared rays.

In fact, riders are more concerned about the cooling capacity of the air conditioner and the ability to quickly cool down inside the car after parking outdoors. After exposure, the air conditioner of this Wuling Hongguang MINIEV was adjusted to the strongest cooling mode. After half an hour, the temperature inside the car dropped to 30.7 degrees, and the cooling capacity of the air conditioner performed well. At the same time, in the first 10 minutes, the air conditioner can reduce the temperature inside the car to 11 degrees, which is more competitive than that of the same class.

Generally speaking, the motor performance of this Wuling Hongguang MINIEV model is not obviously attenuated in summer, and the battery performance of the car is stable. The cooling capacity of the car air conditioner and the ability to quickly cool down the car are more competitive, and the quality of the car is good, which has withstood the high temperature test.

　　IT House reported on November 21st that the appearance of the first luxury car of HarmonyOS Zhixing Zunjie brand will be publicly unveiled at the Huawei Mate 70 series mobile phone conference on November 26th. Yu Chengdong, managing director of Huawei, chairman of BG and chairman of BU, a smart car solution, announced today that the size of Zunjie’s first car is about 5.5m..

　　Yu Chengdong said that the size of the first car in Zunjie may exceed 99.99% of the cars on the road, which is definitely "heroic atmosphere" and "more internal space".

　　HarmonyOS Zhixing "Zunjie" was jointly built by Jianghuai and Huawei. At present, the appearance of the new car has not been announced yet, and IT House will follow up the follow-up news.

　　For reference, the Golden Sunflower Guoya ultra-luxury executive sedan sold by FAW Hongqi at this year’s 2024 Guangzhou Auto Show starts at 1.4 million yuan and has a length of 5353mm (over 5.3 meters). In other words, the first car in Zunjie is longer than the size of Guoya.

The two months in 2024 are fleeting. Just entering March, major new energy vehicle companies have announced their sales results in February. According to the latest data, Guangzhou Automobile’s sales volume in February was 16,676, compared with 30,086 in the same period last year, down 44.57% year-on-year, and down 33.15% month-on-month compared with 24,947 in January. It is not difficult to see that there has been a huge decline in both year-on-year and quarter-on-quarter, and it also showed a downward trend in January this year. In January, the sales volume of Ai ‘an was 24,947 vehicles, compared with 45,945 vehicles last month, that is, in December 2023, the sales volume dropped by 45.7%, almost half. This means that after entering 2024, the sales volume of GAC Ai ‘an has been declining for two consecutive months, and the total domestic and international sales volume in January and February is only 41,623, which is less than the level of 50,000 vehicles sold in the peak month last year.

The performance of this sales data of GAC Ai ‘an is really worrying. You know, in 2023, with the annual sales volume of over 480,000 vehicles, GAC Aian ranked among the top three manufacturers of new energy vehicles, second only to BYD and Tesla China, and compared with 271,000 vehicles in 2022, Aian achieved a year-on-year increase of 78% in 2023. Not long ago, Gu Huinan, general manager of Guangzhou Automobile Ai ‘an, said in an interview with the media that the annual sales of 500,000 vehicles is a "hurdle" for automobiles, and Guangzhou Automobile Ai ‘an hopes to cross this hurdle this year. The sales target for this year is to strive for 700,000 vehicles. This means that in 2024, the average monthly sales volume of GAC Ai ‘an will reach about 60,000 vehicles to achieve this sales target. However, judging from the sales trend in the first two months of this year, it is a bit difficult to complete this figure.

Undeniably, the competition in the domestic automobile market is very fierce now, and all major automobile companies are under great competitive pressure. In this fierce competition, Ai ‘an is facing not only the decline of sales volume, but also the double test of brand and market positioning. Founded in 2017, Ai ‘an, formerly known as Guangzhou Automobile New Energy, belongs to a branch of Guangzhou Automobile Passenger Car. With the rapid development of new energy automobile industry, Ai ‘an left Guangzhou Automobile Passenger Car in 2020 and officially declared its independence. The data shows that from 2018 to 2023, the annual sales volume of Ai ‘an was 20,000, 40,000, 60,000, 123,700, 271,000 and 480,000 respectively. It can be said that in just over six years, the achievements made by Guangzhou Automobile Ai ‘an are dazzling.

However, behind the high-speed growth, Ai ‘an also has an embarrassing worry. In the sales composition of Guangzhou Automobile Ai ‘an, online car rental accounts for a considerable proportion. According to the data, as early as 2021, 43% of the total sales volume of Guangzhou Automobile Ai ‘an came from the B-end sales market, in which the proportion of sales contributed by AION S at the B-end reached 63.01%, and the proportion of AION Y also accounted for 20.33%. As we all know, B-end is easy to load, but its disadvantages are also obvious, which is easy to pull down the product positioning and is not conducive to the later product volume. The car of Guangzhou Automobile Ai ‘an is considered to be sold only to the B-end market, and the ability of the product to enter the C-end market has not been verified.

Gac ean has also tried to turn things around. Since 2020, it has launched two models, namely AION V with a price of 159,900-232,900 yuan and AION LX with a price of 286,600-469,600 yuan. However, the sales volume has always been tepid, and the monthly sales volume of AION LX is even only a few dozen. It seems that it is difficult to break the deadlock. At present, AION S and AION Y are still the main sales models of Guangzhou Automobile Ai ‘an, but now, the sales of these two models have declined, which also directly affects the sales of Ai ‘an brand.

In addition, it is worth noting that there are also problems in the product layout of GAC Ai ‘an. The focus of Geely and Changan’s layout is in the range of 100,000-200,000 yuan, while GAC Ai ‘an is basically building a high-end brand Haobo throughout 2023. Especially in February this year, after BYD played the banner of "electricity is lower than oil", many car companies have taken official reductions or lowered the guide price of new models. According to Uncle Che’s incomplete statistics, at least 15 car companies or brands have introduced preferential measures such as "official reduction".

However, several models owned by Ai ‘an have only introduced some new models and the so-called free charging policy. For example, on March 3, an Ai ‘an AION Y Plus 310 Star Yao version was launched. Although the price dropped below 100,000 yuan, the pure battery life under CLTC condition was only 310km. In the new energy market in 2024, this endurance capacity was not competitive compared with competitors, and the related intelligent and comfortable configuration was also reduced. To tell the truth, compared with the cash discount of 20 thousand or even 30 thousand or 40 thousand for friends, these have no impact and competitiveness at all. At present, in 2024, the brand of Ai ‘an will not launch a particularly heavy and powerful new car one after another, so it is quite reasonable to encounter the sales dilemma.

At the same time, Che Shu also found that in the past year, GAC Ai ‘an received the most complaints from users, and it was also the most popular model of GAC Ai ‘an. The most intensive complaint was that the cruising range was not allowed. However, the problem of inaccurate cruising range of models owned by Guangzhou Automobile Ai ‘an has been around for a long time. As early as 2021, users began to complain about AION Y on the automobile quality platform. The 500-kilometer battery life can only run 350 cars and get a 50% discount at high speed.

And not only AION Y, but also AION S occupies a very high proportion. In 2022, the scandal of "power-locking" broke out in Guangzhou Automobile Ai ‘an. Many owners of AION’s reported that the manufacturers locked the power privately through OTA upgrade without the consent of the owners, resulting in a general decrease in the cruising range of vehicles and a weakening of power, which seriously affected the normal car life of car owners and was questioned by consumers as "sales fraud" and "false propaganda".

Today, consumers’ consumption concept is becoming more and more mature and rational. Enterprises need to take their due responsibilities when problems occur, give consumers a satisfactory answer and solve them in time, which is the long-term way to survive. However, judging from the current complaints of GAC Ai ‘an, it seems that GAC Ai ‘an has not effectively rectified related problems. AION S and AION Y are the main sales force of GAC Aian. It can be said that if GAC Aian does not have AION S and AION Y, I believe its monthly sales volume will be even more ugly.

In this fierce competition, GAC Ai ‘an tried to transform its brand image by launching a brand-new high-end brand Hyper Haobo, in an attempt to find a new living space in the high-end market. In September, 2022, GAC Ai ‘an released Hyper Haobo, a high-end luxury brand. At present, there are three models on sale, namely Haobo SSR positioned as a sports car, Haobo GT (parameter picture) of a medium and large luxury car and Haobo HT of a medium and large SUV. Haobo GT and Haobo HT are the main sales models, and the price is between 21.39-33.99 million. However, the reality is not satisfactory. The market performance of these two models has not reached expectations, and the monthly sales volume is even more unsatisfactory.

Take Haobo GT, its main sales model, as an example. Haobo GT was officially listed in July 2023. At the beginning of its release, GAC Ai ‘an called it "the trump card model" and declared at the press conference that "no car can shake the dominance of Model 3 until Haobo GT arrives". As the representative model of the 20 millionth new energy vehicle in China, it is a heavy model with high hopes, but from the current sales performance, the performance of Haobo GT is not very satisfactory.

From its listing in July 2023 to January 2024, Haobo GT only sold more than 2,000 vehicles in July 2023, and the sales in other months were less than 800 vehicles, even less than 500 vehicles in some months. Among them, in January 2024, the sales volume of Haoplatinum GT was only 315 vehicles, which was 27.58% lower than that of last month, almost 30% lower. Obviously, no matter from the perspective of sales scale or sales trend, the performance of Haoplatinum GT is not brilliant.

In 2024, the involution of the new energy vehicle market will intensify. Tesla has started to reduce the price. Extreme Krypton 007 has pulled the price of 800V high-voltage fast charging to around 200,000, while Galaxy E8 has pushed the price of B-class pure electric cars to around 170,000. GAC’s exploration in the mid-to high-end market seems to have met an invisible wall. In addition to traditional car companies, there are also brands such as Weilai, Tucki and Ideality that have been deeply involved in this field for many years, and have solid brand influence and product competitiveness. It is undoubtedly necessary for GAC Ai ‘an to take a slice of the Red Sea. In 2024, Yu Guangqi ‘an is destined to face a more severe test.

Che Shu concluded

Since 2023, the word "volume" has been running through. At first, Skyline, Aichi and Weimar were out of the game. Since 2024, Gaohe has also heard regrettable news. At the moment when the involution of domestic new energy vehicles is intensifying, consumers have more comparisons and choices, and it is difficult for major car companies to win the favor of consumers if they don’t show a little "hard power". In particular, Geely, Chang ‘an, Great Wall and many other domestic veteran car companies are rushing on the road of transformation, and they are constantly "competing" with each other, and each company has its own strengths. Whether in product innovation, brand building, market expansion or service improvement, GAC Ai ‘an needs continuous intensive cultivation. Facing the future, GAC Aeon needs both courage and wisdom. Only by constant adaptation and innovation can we keep a steady pace in this ever-changing market, otherwise the decline in sales and the loss of people’s hearts are also predictable results.

The CX6672 graph data transmission module empowers the data link of the new generation UAV.

UAV data link is an important part of UAV system, and it is the link between aircraft and ground system. UAV data link can be divided into uplink and downlink according to transmission direction. Uplink mainly completes the sending and receiving of remote control instructions from ground station to UAV, while downlink mainly completes the sending and receiving of telemetry data (flight control) and video images (image transmission) from UAV to ground station, and uses uplink and downlink for ranging according to the transmission of positioning information. The performance of data link directly affects the performance of UAV. According to the time and function, the UAV data link is divided into three stages:

The first stage: data transmission, which is mainly used for data transmission between flight control and ground stations. The main purpose is to adjust parameters, telemetry data and remote monitoring. Moreover, parameters can be adjusted during flight and flight data of flight control can be transmitted back, but large-capacity data cannot be transmitted.

The second stage: image transmission, which is used to meet the needs of high-resolution image/video real-time transmission for aerial photography, maintenance, measurement, mapping and monitoring. The UAV needs to be equipped with a wireless communication module that can realize wireless image transmission. At this stage, the image transmission mainly adopts two technologies: WiFi image transmission and COFDM radio image transmission. WiFi image transmission has the characteristics of low cost and small size, and it is quickly popularized in consumer drones. However, WiFi technology is designed for indoor static close range, and its transmission distance is only a few hundred meters, so it cannot be transmitted over a long distance. And the mechanism of WiFi carrier sense determines that it cannot be used reliably in multi-unit networks. COFDM radio station follows DVB broadcasting technology, which has high spectrum efficiency and long transmission distance, and can be applied to industrial UAVs with long-distance transmission. However, COFDM radio station generally adopts one-way broadcast transmission, which can not be used in networking, and the cost is very high. At present, it is gradually replaced by LTE image transmission with networking capability.

The third stage: digital and graphic transmission, multi-unit network. Traditional data transmission and image transmission all adopt independent modules, which occupy a large volume and consume a large amount of power. The new data link graph integrates data transmission, wide and narrow bands share wireless links, and the uplink and downlink are transmitted in both directions, which improves the efficiency of spectrum use. Single module supports serial port, network port, USB, HDMI and other interfaces; Serial port is used for data transmission, and network port, USB port and HDMI port are used for image transmission. With the rapid popularization of power line inspection, highway inspection, border inspection, surveying and mapping, fire prevention and other industries, the single-control single-machine mode can no longer meet the requirements. On the basis of two-way networking, multi-machine and multi-station networking is required.

Based on the application requirements of the above UAV scenes, Chenxin Technology launched the CX6672 graph data transmission module. Based on the SDR chip platform of Chenxin Technology, this module supports broadband data transmission of point-to-point and point-to-multipoint star networking. This module is based on LTE wireless communication standard and adopts.OFDM(orthogonal frequency division multiplexing) andMIMO(Multi-Input & Multi-Output,) and so on.technologyDifferent modulation and coding methods can be applied to adapt to different channel changes and obtain the maximum transmission efficiency.

Typical application scheme: high-speed functional automatic inspection system

A number of ground base stations are deployed along the expressway, and each ground base station is connected with the monitoring center through optical fibers. When the UAV patrols along the expressway and reaches the wireless coverage area of a base station, the patrol video image is transmitted back to the command center through the base station; When the UAV flies to the coverage area of other base stations, it automatically switches transmission paths seamlessly, and data is not lost during the switching process.

With the increasing economy, the domestic environment for playing with cars is getting better and better. Many economically affluent consumers want to buy an off-road vehicle. herdsman (parameter picture) and Prado are the first choices, but the price is too expensive, which blocks too many consumers from off-road doors. The Haval H9, which is much cheaper, was once the first choice for many consumers who love off-road. However, since the Great Wall introduced the tank 300, many consumers have turned their attention to this one, which looks more beautiful. Today, let’s take this opportunity to explain the tank 300 in detail, and provide some reference for consumers who are interested in this car.

There are four models of Tank 300 currently on sale, and the guide price is between 17.58 million and 220,000 yuan, among which the tribute to Monet limited edition is a new model launched in 2021.

In terms of body color matching, there are six options for Tank 300, namely Bai Fumei, I want red, Big Wolf, Tender Blue, Heart-warming Orange, and Black Pineapple. Among them, the blue body is only available for the limited edition of Monet.

All models of tank 300 maintain the same design technique in appearance, and the thick lower bumper is blackened, which is very wild. At the same time, it also takes into account the situation of bumping or rubbing in the off-road process to avoid unnecessary losses. The middle net part is composed of three high-gloss horizontal grilles, and the retro-flavored round-hole headlight shape instantly creates the taste of a classic hard-core off-road vehicle, and the overall sense of matching with the middle net is also excellent.

All models of the headlights also maintain the same design technique. Although it is a tribute to the classic round-hole headlights, the internal light cavities of the tank 300 are arranged in a matrix, and the light bars extending to the outside take into account the aesthetic feeling and sense of science and technology on the whole.

The design language of the side of the car body is relatively simple. The square box body is the usual design of most hard-core off-road SUVs, and the tank 300 is no exception. The high wheel eyebrows can make the vehicle get better suspension stroke during off-road, and also reserve a lot of space for later modification. In terms of body size, the length, width and height of the four models are all 4760mm*1930mm*1903mm, and the wheelbase of 2750mm is quite satisfactory in the field of compact SUV. In addition, the minimum geographical gap of the tank 300 is 224mm, and the maximum wading depth is 700mm, while the maximum wading depth in approach angle is 33 degrees, the departure angle is 34 degrees and the maximum climbing degree is 70 degrees. From these parameters, it can be seen that the tank 300 meets almost all the standards of hard-core off-road vehicles, and even compared with the benchmark model herdsman, the tank 300 is not afraid at all.

The four models of Tank 300 all use 17-inch five-frame wheels, and the tires are made of three brands, namely, Han Tai’s Wantushi S2 ASX series, Kumho’s CRUGEN HP71 series and finally Cooper’s DISCOVERER ATT series. If you are not a heavy extreme cross-country player, in fact, Cooper’s ATT all-terrain tires are completely enough.

Finally, let’s look at the tail. The external spare tire is a common design of most hard-core off-road SUVs, and the thick bumper once again sets off the original wildness of the vehicle. The back door of the tank 300 is opened as a whole, so it may not be convenient to place items on the higher platform, but considering that the chassis of hard-core off-road vehicles is generally higher, it is not so unacceptable.

interior decoration

At present, the tank 300 has two options of black and black/blue mix and match, but only the top-of-the-line tribute Monet limited edition has a blue interior, and all other models are black. The design language of all the models in the whole department remains the same. The air outlet of the round hole air conditioner is very hard-core, and the penetrating large screen is dotted with a sense of science and technology. The electronic gear handle similar to the aviation propeller also cites some exoskeleton decoration, which is really pleasing. The tank 300 can fully match the positioning of luxury brand models. The center console and the door panel are all designed with large leather stitching and wrapped with soft materials, while the brushed decorative board on the co-pilot center console and a large number of chrome-plated materials in the car further enhance the exquisiteness of the interior.

Internal configuration

The steering wheel wrapped in leather is used in the whole system. The multi-function control and shift paddles of the steering wheel are not absent from all models. The conqueror and tribute Monet limited edition is also equipped with steering wheel heating function. Finally, only the Explorer is equipped with a 10.25-inch full LCD instrument panel, and the other three models are all 12.3 inches.

In the intelligent interconnection configuration, Explorer is equipped with a 10.25-inch central control screen, while the other three models use a 12.3-inch central control screen. Functions that are often used in daily life, such as GPS navigation system, Bluetooth car phone, car networking function, voice recognition control system, etc., are given to all models in the whole department. One thing about the internal configuration of the tank 300 is not very pleasing. Due to the lack of a large number of physical buttons, most functions are almost integrated in the car system, so the convenience of daily operation may not be very good.

Passive safety

Tank 300′ s low-profile model Explorer was given only two airbags in the front row, and challenger had more airbags in the front row, giving a total of four airbags in the car. Conqueror and tribute Monet limited edition was also equipped with side airbags, with a total of six airbags in the car. Finally, all models are equipped with tire pressure display function as standard.

Active safety

As for the active safety configuration, the low-equipped Explorer only gave the basic primary safety configurations such as ESP and EBA, while the other three models were equipped with four configurations: lane departure warning, lane keeping assistance, fatigue driving warning and road traffic sign recognition.

Auxiliary control

Finally, let’s take a look at the auxiliary control configuration. The Explorer has given the rear parking radar, reversing image and cruise control function as standard. In addition, the front and rear axle differential locks can be optional. In addition to the optional front axle differential lock, the challenger is provided with other configurations directly, and all auxiliary control configurations of conqueror and tribute Monet limited edition are available. Finally, the central differential locking function and low-speed four-wheel drive mode are standard functions of all models.

Of the four models of tank 300, only Explorer is not equipped with sunroof function, and all other models are equipped with single sunroof, and Explorer has not given it to the roof rack. The pedals on the side of the car are only supported by the limited edition of Monet, and the other three models use fixed pedals.

Explorers are equipped with conventional 6 speakers, challengers with 9 speakers, and conqueror and tribute Monet limited edition with 9 speakers of Infinity brand.

All models in the whole system are equipped with automatic air conditioning, and all other models support temperature zone control except Explorer.

Seat space

The seat material is made of fabric, the challenger is made of imitation leather, and the conqueror and tribute Monet limited edition is made of Nappa leather. In terms of configuration, there is only a low-profile explorer, not equipped with electric adjustment of the main and passenger seats, as well as heating and massage functions of the front seats. The conqueror and tribute Monet limited edition is also equipped with ventilation functions of the front seats.

Finally, let’s take a look at the rear seat configuration. The whole system comes standard with air conditioning air outlet, armrest cup holder and two USB ports. In the measured space, passengers with a height of 170cm can get a head allowance of one punch and three fingers in the front row, and when they come to the back row, they can get two punches directly, and there are more than two punches in the leg space. Thanks to the body structure of the square box, the tank 300 is really excellent in the measured space performance, especially the concave design of the rear roof, which can further improve the head space in the back row.

motive force

The standard 2.0T engine in the whole system has a maximum power of 227 HP and a peak torque of 387 Nm. This engine is the same as the engine above VV6 and VV7, and it is very beautiful just from the book parameters, but how to drive it, we have to look down. In the actual driving process, the dynamic response of this 2.0T engine is relatively positive. As long as a little throttle is given, the linear power will be continuously delivered. However, being positive does not mean rushing, and it will not give you the feeling that your home SUV has a sharp throttle, and it will not be too conservative. To sum up, it is enough, smooth, and not in a hurry.

The 8AT gearbox from ZF is a huge bonus item for Tank 300. It is known that this gearbox has always been a difficult problem in adjustment. However, this 2.0T engine on Tank 300 is well coordinated with the 8AT gearbox, and the gear shifting of the gearbox will not be too active during high-speed driving. Everything is based on ride comfort, which is actually a typical "ZF style". In addition, the smooth shifting process and clear shifting logic can’t pick out any faults, and this gearbox also performs well in grasping the timing when shifting gears.

For a hard-core off-road vehicle, a mature four-wheel drive system and a sound differential are particularly important, and the tank 300 is equipped with the part-time 4wd system from Borgwarner. The biggest feature of this system is the strong rigid connection, which can realize 50: 50 power transmission before and after being completely fixed and locked, and at the same time, add 2.48 times amplification torque of the central transfer case, so that the tank 300 can ensure excellent passing ability when facing up and down slopes and complex road conditions. In addition, the Eaton tooth-embedded differential lock will not be stuck in the process of hanging in and taking off, which is very fast and the overall performance is commendable. Finally, the tank turning and four-wheel drive low-speed crawling mode are good news for off-road white.

The tank 300 adopts the combination of front double wishbone independent suspension and rear multi-link dependent suspension, and the front shock absorber combined with double wishbone structure makes the tank 300 show good support in the face of multi-curved road conditions with large drop. At the same time, the shock absorber can respond quickly to some bumps and small vibrations on the road surface, so as to control and filter in time, and the overall comfort is excellent.

Configuration analysis

There are only four models of tank 300 currently on sale, and the power and appearance are also consistent. Therefore, considering the cost performance, we can draw a conclusion by directly combining the price and configuration. Based on this idea, the author selected a recommendation: Challenger.

> > 2021 tank 300 2.0T off-road challenger 195,800 (recommended index: ★★★★★ ★).

Since the positioning is a 200,000-level hard-core off-road, the challenger is undoubtedly the best choice in terms of comprehensive price and configuration. The price of 195,800 plus money to install a front axle differential lock is equivalent to having a complete set of off-road hardware. In addition, the configuration is also quite rich, such as lane departure warning, lane keeping assistance, 360-degree panoramic image, front seat heating, massage, and L2 automatic driving, etc. Even if you are a user with requirements for configuration, the challenger of Tank 300 can fully meet your needs. Therefore, 200,000 can have a complete set of hard-core off-road hardware and a rich configuration group. Personally, I think the challenger must be the one with the most outstanding cost performance and the most suitable purchase among the four models.

Tank 300 has been given high hopes since its birth. It is necessary to know that hard-core off-road vehicles have no audience, and domestic independent brands do not have many masterpieces in this respect. The appearance of the tank 300 eased this situation a little.
