The challenging plateau extreme environment is the most rigorous testing ground for off-road vehicles. As a representative of off-road field, Toyota Land Cruiser is famous for its long history and strong off-road ability, and is deeply loved by senior off-road players. As a new cross-country species, Dongfeng Warrior 917 not only inherits the cross-country genes of military warriors, but also incorporates intelligent electric technology, successfully opening the luxury road of hard-line cross-country. On the plateau, who is better between the two? Only after the comparison will we know!

Power system competition, whose performance is stronger?

In the off-road field, Toyota Land Cruiser has always been known for its powerful performance and reliability. It is equipped with a 4.0L V6 naturally aspirated engine with a torque of 385 Nm. However, in the plateau area, this car has encountered obvious challenges. Due to the high altitude, thin air and low air pressure in the plateau area, the engine intake of Land Cruiser is significantly reduced and the fuel combustion is insufficient. This directly led to a sharp decline in its dynamic performance, and the original strong power became soft and weak on the plateau.

In contrast, Dongfeng Warrior 917 provides more diversified power options, including pure electric version and extended range version. The pure electric version adopts a four-motor four-wheel drive system, with a horsepower reserve of up to 1088Ps, and the acceleration time of zero hundred is only 4.2 seconds, which can maintain strong power output even in the plateau environment. The extended-range model is equipped with three motors and a 1.5T range extender, with a horsepower of 816 horsepower and a CLTC comprehensive cruising range of 1,026 kilometers. Because the range extender is not directly involved in driving, the power is slightly affected by the altitude change, providing stable and sufficient power in the plateau area.

Who can provide more comfortable driving experience in suspension system competition?

Suspension system plays an important role in vehicle performance, comfort and passability. The rear axle of Toyota Land Cruiser adopts dependent suspension (integral bridge type). Although this structure can provide better bearing capacity and passability under complex road conditions, when driving at high speed under continuous potholes, the overall bumpiness of the vehicle is relatively strong, which affects the ride comfort.

Dongfeng Warrior 917 is equipped with AeroRide multi-stage intelligent adjustable air suspension from BWI Jingxi, equipped with 5-speed adjustment, supporting 150mm long-stroke suspension height adjustment, supporting 45mm downward adjustment and 105mm upward adjustment, which can realize multi-body attitude adjustment, support body height adjustment, body height maintenance, easy loading, suspension welcome function, and take into account multiple requirements of off-road, fuel economy and convenience of boarding and descending. The maximum ground clearance of 335mm can be reached in the extrication mode, which brings strong road trafficability.

Steering system competition, who can bring better handling?

Today, with the continuous innovation of automobile technology, the performance of steering system directly affects the driving experience of vehicles. The R-EPS electric power steering system adopted by Dongfeng Warrior 917 has higher steering efficiency than the common EPS system of ordinary off-road vehicles. At the same time, the R-EPS electric power steering system has stronger axial load capacity. This makes the steering system of Dongfeng Warrior 917 work stably and maintain good handling performance when it bears a large load and impact, which provides a strong guarantee for the reliability and safety of the vehicle.

In sharp contrast, the traditional hydraulic power steering system adopted by Toyota Land Cruiser. Due to the characteristics of its mechanical structure, it may increase the driver’s driving fatigue when driving for a long time or needing frequent steering operations. More crucially, in the plateau environment, the hydraulic power steering system is facing severe challenges, and hydraulic oil pipes and other components are prone to air resistance, which will directly affect the working performance of the system, resulting in slow and inaccurate steering response, and may even endanger driving safety in severe cases.

Brake system competition, braking can only play wild.

Toyota Land Cruiser is equipped with mechanical hydraulic braking system, which is famous for its stable and reliable braking torque. However, in this special environment of plateau area, due to high altitude and large temperature difference between day and night, these extreme conditions put forward a severe test for the performance of hydraulic oil. In low temperature environment, the fluidity of hydraulic oil becomes worse, which may lead to the slow response speed of the braking system, thus affecting the braking effect; However, at high temperature, the hydraulic oil pipe is prone to air resistance, which further reduces the braking efficiency. These problems not only affect the driving comfort, but also affect the driving safety to some extent.

Facing the challenge of plateau environment, Dongfeng Warrior 917 adopted a more advanced IBC hydraulic brake-by-wire system. This innovative technology directly controls the braking system through electronic signals, and accurately controls the flow and pressure of hydraulic oil, thus achieving accurate control of braking force, which significantly improves the braking effect and safety. Compared with the mechanical hydraulic braking system, the brake-by-wire system has faster response speed and higher sensitivity, and can respond to the driver’s braking instructions more timely.

Who is the more reliable travel companion in the security competition?

In the automotive field, safety has always been one of the core elements that consumers are most concerned about. Toyota Land Cruiser adopts TNGA architecture, the body is welded by laser, and the frame is mainly made of high-strength steel. This kind of steel has excellent tensile strength and yield strength, which can effectively absorb and disperse energy during collision and protect the safety of occupants in the car. In addition, the key parts of the car body, such as A-pillar, front pillar and roof beam, are reinforced with multi-layer structure and high-strength steel plate to further improve the rigidity and anti-collision ability of the car body.

Dongfeng Warrior 917, as a luxury electric off-road vehicle, adopts the technology of ultra-high-strength internal high-pressure integrated molding of longitudinal beam pioneered by non-loaded off-road vehicle in China, and uses high-pressure water medium to close the cavity for expansion, which can make the longitudinal beam stable in size, without weld, welding scale and welding slag, and welding thermal deformation. Due to the cold work hardening effect of expansion, the strength of parts is improved by 10% compared with the strength of materials. The frame structure is made of high-strength materials, and the coverage rate of high-strength materials from 600~800Mpa to 800 MPa is more than or equal to 85%. The high coverage rate ensures the strong and durable performance of the car body and ensures superior passive safety protection.

Four-wheel drive system competition, who has stronger ability to get rid of difficulties?

As we all know, the ability to get out of trouble is one of the core indexes for verifying off-road vehicles. As an evergreen tree in off-road field, Toyota Land Cruiser’s full-time four-wheel drive system has always been its proud capital, and it has won the favor of many consumers with its excellent comfort, stability and long-distance crossing ability. However, the domestic version of the Land Patrol lacks the front and rear differential locks in the four-wheel drive configuration, which makes it slightly inadequate in the face of extreme off-road conditions.

In contrast, Dongfeng Warrior 917 is equipped with electronically controlled mechanical differential lock and central virtual differential lock, which can achieve 100% mechanical locking, which not only improves the efficiency of torque transfer, but also ensures the stability and passability of the vehicle under extreme conditions. This configuration allows the Warrior 917 to face all kinds of complex terrain with ease and easily challenge extreme off-road conditions.

At the same time, Dongfeng Warrior 917 is the only vehicle in China that has passed the durability test of "National Military Standard" (GJB). After four rounds of military standard durability test, the total mileage exceeds 1 million kilometers, and the actual mileage of equivalent users is nearly 6 million kilometers, covering 99.5% of user usage scenarios. Among them, off-road working conditions, mountainous areas, mining areas and other extreme working conditions account for as much as 50%, ensuring that vehicles can maintain reliable operation under any circumstances, showing excellent reliability and durability.

With the continuous progress of science and technology, the automobile industry is undergoing changes. Dongfeng Warrior 917 has become a new dark horse in the off-road field with its advanced technology configuration and excellent performance, and has also set a new benchmark for domestic off-road vehicles. Traditional fuel off-road vehicles, such as Toyota Land Cruiser, may also need continuous innovation in technology to cope with the ever-changing market demand and environmental challenges.

　　For consumers, the number of models to choose from has increased. When buying a car, consumers have to ask relatives and friends one by one about the use of each model, as well as their satisfaction with the model. Buying a car has become cumbersome, and our "2005 Domestic Car Consumer Satisfaction Survey Report" will be recommended to you as a good car purchase reference. After the successful holding of the "2004 Domestic Car Consumer Satisfaction Survey", consumers have evaluated it as one of the best topics of the "Car Shopping Guide" year. In order to make the satisfaction survey more complete, we started the 2005 satisfaction survey in early February 2005. After more than three months of questionnaire collection, collation, and supplementary surveys, it was then handed over to a professional survey company to analyze the questionnaire and statistical results. Now, it has made a grand debut with the efforts of all parties.
　　Consumer Satisfaction Index (CSI)
　　Customer satisfaction is a level of consumer perception, and a deeper meaning refers to the degree to which the performance of the product (service) provided by the enterprise matches the current expectations of consumers.

　　The Customer Satisfaction Index is a measure of consumer satisfaction, expressed as a percentage. For this survey, the Consumer Satisfaction Index is used to indicate the overall satisfaction of a car brand in terms of quality, performance, appearance, interior, after-sales services, and car maintenance costs.
　　Improvements to the 2005 Consumer Satisfaction Survey
　　1. In 2004, our questionnaires came from a variety of methods such as clipped questionnaires, face-to-face interviews, and online surveys. In 2005, more than 95% of our questionnaires came from clipped questionnaires, which was more direct and effective, increasing the efficiency of our questionnaires from 64% in 2004 to more than 92%.

　　5. More manufacturers are participating and paying attention. Due to the greater influence of consumer satisfaction surveys, some manufacturers have taken the initiative to contact us and attach great importance to the survey results.
　　The results of this investigation
　　New models such as Elantra, Fit, Audi A4, Corolla, and Peugeot 307 score relatively high, with their novel appearance, leading technology, and good performance. After-sales services can also keep up. Consumers have shown strong interest and high satisfaction with these new models, and their sales are also very optimistic.

　　This survey covers a wide range, involving 30 provinces, municipalities and autonomous regions across the country. In the same way as the previous survey, we will divide the content of the survey into 5 major aspects such as external quality, internal quality, performance, after-sales services and maintenance costs. These 5 major aspects include 18 sub-categories. In the chart below, we will list the scores of each model in 18 sub-categories (converted to √ and ×). At the same time, since there are many models involved in this survey, we focus on the top two or three models in each class.
　　(Table 1) Model price range division

　　Accord ranked second overall

　　Although the mid- to high-end car market has shrunk significantly, the Accord has become an extreme, which is inseparable from the Accord’s high satisfaction. In the 2005 satisfaction survey, the Accord’s score rose to more than 80%, becoming one of the two major models with a score of more than 80% in this satisfaction survey.

　　Owners also put forward suggestions for improvement in the details of the Accord, such as the rearview mirror is prone to water accumulation; the luggage compartment space is not very reasonable; the sound effect is average; the high-speed wind noise is relatively large, and the sound insulation device should be added; the configuration (such as GPS satellite positioning system and reversing radar) should be added.

　　Passat ranked third overall

　　Consumers have also proposed some improvements to the Passat, including: low configuration, sunroof, DVD, EBD and TCS, reversing radar should be standard; at the same time add electronic navigation system, electric adjustable seats and electric heating system; improve fuel economy; reduce the price of spare parts and maintenance costs. In addition, the seat is not comfortable enough for long-distance travel, and the sound level is low. These aspects should also be improved.

　　(Table 3) Satisfaction evaluation of 80,000~ 180,000 yuan mid-class car

　　(Table 4) Satisfaction evaluation of 50,000~ 80,000 yuan economy car

　　Consumers also put forward some improvement suggestions for SPARK, such as the higher price of spare parts; the small number of after-sales service stores, which is inconvenient to maintain; poor sealing; the blind spot of the A-pillar is large; the maintenance cost is higher; the chassis is slightly lower.
　　(Table 5) Satisfaction evaluation of mini cars under 50,000 yuan

　　(Table 6) Satisfaction evaluation of premium cars above 300,000 yuan

　　As the number of new models continues to increase, consumers can choose from more models, and our satisfaction survey will include more and more new models, even MPVs and SUVs. At the same time, we also hope that more and more consumers and manufacturers will participate, making this survey the most authoritative and comprehensive reference for consumers when purchasing a car.

Meeting with representatives of the development and launch of satellites

Inspire the people of the whole country

On the night of the first International Labor Day in the 1970s, Mao Zedong met with representatives of the development and launch of Long March rockets and Dongfanghong satellites on the Tiananmen Gate, reflecting his concern for the aerospace industry and his encouragement to astronauts.

After the satellite launch was successful, Zhou Enlai arranged for the development and launch personnel to participate in the observation of the Tiananmen Gate Tower on the evening of the "May Day" International Labor Day.

▲ On May 1, 1970, Chairperson Mao received representatives of the personnel who developed and launched the "Dongfanghong-1" satellite

Warmly shake hands with the delegates, express condolences and congratulations

The seats of the delegates were carefully arranged at the exit of the elevator on the west side of the city building, which is where the central chiefs have to go back and forth. That night, Mao Zedong, Zhou Enlai and others accompanied Prince Sihanouk to the Tiananmen Gate Tower, and Chinese and foreign guests celebrated the festival of working people all over the world.

The leading comrades who specifically organized the implementation of the task, as well as the representatives of the research and development and launch test units, stood in formation on the long corridor to the right of Tiananmen Gate to watch the celebration.

Zhou Enlai guided Mao Zedong to the front of the team and introduced:

Chairperson, they are the staff representatives of the development and launch of satellites, and they just arrived in Beijing yesterday.

Mao Zedong smiled and happily shook hands with the delegates one by one, expressing his cordial condolences and congratulations.

The films shot by photographers back then left us with precious images, the excited smiles of astronauts and the images of shouting slogans, which have been indelibly recorded in the history of the development of New China and the struggles of astronauts.

▲ Mao Zedong and Zhou Enlai

The second handshake and the long viewing ceremony made the astronauts unforgettable

After the party, when Zhou Enlai led Mao Zedong to withdraw, he walked past the representatives of the satellite launch, who competed to shake hands with Mao Zedong for the second time.

At that time, Liu Fuyu, the leader of the electrical measurement team of the satellite assembly workshop who did not catch up with the first handshake, recalled this incident decades later:

By the time they arrived at Tiananmen Gate, the party had already begun.

Qian Xuesen said regretfully:

Chairperson Mao has already received our delegation, but you missed it.

Unexpectedly, Mao Zedong received the delegation for the second time, and he finally shook hands with Chairperson Mao happily.

The satellite launch was successful! Mao Zedong offered his condolences to Qian Xuesen’s team at the Tiananmen Gate and shook hands one by one.

There was another detail that also left a deep impression on the astronauts who attended the party. On the night of "May Day", Mao Zedong spent a long time in Tiananmen Square.

According to Wang Shengyuan, who was in charge of satellite surveying and received by Mao Zedong at the time, he recalled:

I remember Wei Tongtai (the head of the Seven Aircraft Department) said at the time that he had participated in three such celebrations. The first two times, Chairperson Mao left before the fireworks were released. This time Chairperson Mao was very happy and left after all the fireworks were released.

Mao Zedong cordially received the successful personnel who developed and launched satellites, which inspired the fighting spirit of the vast number of astronauts and encouraged the construction of a modern socialist power.

Tell the astronauts not to be proud

To launch more Chinese satellites

After China’s first satellite was launched, Mao Zedong brought up the topic of satellites many times in his conversations with foreign guests over the past two years.

The central idea we read from this is that China has only launched one satellite, which is nothing. Mao Zedong’s arguments at the time were quite intriguing.

Wang Zhanhua, a satellite launch representative who attended the "May Day" Tiananmen ceremony, recalled:

Chairperson Mao said to the people that there are more than 2,000 satellites in the sky, and we are only one in 2,000! Even if there are 2,000 satellites, we can’t be proud, otherwise we will go to the opposite side. This is a lesson. All of us were deeply encouraged and promptly organized all units to study Chairperson Mao’s instructions carefully.

The 2013 "Chronicle of Mao Zedong" revealed similar words from later Mao Zedong, and more than one time. Mao Zedong’s words are slightly different and his meaning is slightly different.

There are so many satellites rotating in the sky, and the Chinese satellite is not a big deal

"Not so much admiration" for China’s satellite launch. On July 13, 1970, Mao Zedong met with a French government delegation. When the guest said that President Pompidou admired China’s scientific efforts, Mao Zedong said:

Just started, experimental. China is not a big country, I don’t believe it when the newspapers say it.

When Bettencourt said she admired China for releasing its own satellites, Mao Zedong said:

I don’t admire it that much, it’s nothing. Because there are so many satellites in the sky, all of them belong to those two countries. What do our countries count as two satellites?

The word used here is "not so admired", which is a reversal of the idea that guests "admire China very much," so it is "nothing". It is "pitiful" to think that launching a satellite is "pitiful". It is said that foreigners "always blow us away".

On September 23, 1970, during a meeting with Vietnamese leaders, he said:

China is not a big country, but a medium country. I debated this issue with France Bettencourt. In a way, we are not even as good as France. How can we be considered a big country?

He always boasted to us that you put a satellite in the sky. I said there are so many satellites in the sky every day, and we only have one, what is it?

The word used here is "what"! Westerners always exaggerate. This conversation can also provide a footnote to our understanding of the debate on "admiration" and "disadmiration" in the July 13 conversation.

Mao Zedong receives foreign guests

Launching a satellite is very pitiful, worrying about how to improve the economy

On July 20, 1970, Mao Zedong met with Congolese guests and said:

There are too many people in China, which is not commensurate with economic development. You are worried about your economy now, and we are also worried about how to improve it. It is not about building a few atomic bombs and launching a few satellites, which is very pitiful. There are many man-made satellites in this sky, all of which are owned by the United States and the Soviet Union. Only France and Japan have run up there. Recently, China has run up one.

The word "pitiful" is used after enumerating the first few countries to launch satellites, and asking "how to get the economy going" is the important question. Humbly put "only two".

On the evening of July 10, 1972, during a meeting with French Foreign Minister Schumann at Zhongnanhai Swimming Pool, Mao Zedong said of the tensions between China and the Soviet Union:

You hit yours, I’ll hit mine. We’ll use the same method we used to hit Chiang Kai-shek and the Japanese.

There are not as many atomic bombs as the Soviet Union, and we only put two satellites in the sky.

The phrase used here is "only two", at a time when China’s space program is in full swing.

Using the afterglow of life to illuminate the future of China’s aerospace industry

In his later years, Mao Zedong’s health and energy were getting worse, but his gaze still did not leave China’s aerospace progress.

When the Dongfanghong satellite was in full swing, on June 17, 1968, Mao Zedong approved the development of the ocean-going survey ship project, code-named "718 Project", which was later named after Mao Zedong’s handwritten poem "Far View" by Marshal Ye Jianying. They participated in the measurement and control tasks of almost all major space activities after launching long-range carrier rockets into the Pacific Ocean (code-named "580 Project").

China’s first ocean-going survey researchers work on deck

On July 14, 1970, Mao Zedong read the National Defense Science and Technology Commission’s "Plan Report on Astronaut Selection" and directed the launch of China’s manned spaceflight program, code-named "714 Project", which was an early rehearsal of China’s manned spaceflight program.

On March 31, 1975, Mao Zedong read the "Report on the Development of Satellite Communication Problems in our country", code-named "Project 331", which led to the "Dongfanghong No. 2" communications satellite that later jumped 36,000 kilometers away from the earth.

On November 26, 1975, the ill Mao Zedong reviewed the report of our country’s launch of remote sensing satellites, and then reviewed the relevant information sent back by the satellites.

Mao Zedong’s earnest instructions and aerospace layout have made the vast number of astronauts modest and cautious, making persistent efforts to promote China’s aerospace industry to make great strides into space.

▲ Chairperson Mao at the meeting

Nowadays, two tapes of "The East is Red" music from space lie quietly in the display case of the Comrade Mao Zedong Memorial Hall, telling the touching story to future generations.

The music of "The East is Red" sings the song in the chest of Chinese astronauts, accompanied by the rhyme of building a aerospace power, and becomes a lasting song of singing China’s aerospace and Chinese dreams.

The emotions and longing of the Chinese people expressed in "The East is Red" complement each other with the great Chinese road, Chinese strength and Chinese spirit, and compose a beautiful movement of the great rejuvenation of the Chinese nation!
