In 1945, after the end, () car decided to develop a brand-new model. At that time, the powerful figures of Rover Company were inspired by a Willis left after the war when they were working in a farmland, and decided to produce a light four-wheel drive multi-functional model. The research and development concept of the new car is that it can drive under bad road conditions such as farmland. The English name ""means "can be used for farming".

The brand of Landrover is of extraordinary significance in the world. From the initial farmer’s car to the luxury SUV, the development of Landrover can be described as ups and downs. Before it was officially sold in China, Chinese people always translated Land Rover into Land Rover. However, when Land Rover was ready to be officially listed in China, it was found that Land Rover had been registered as a trademark by a domestic automobile company, so it had to register the "Land Rover" trademark in China.

The first Land Rover was born in 1948. The predecessor of Land Rover was an agricultural truck, which used the chassis and transmission system of the US military Willis jeep. Other parts were made by itself, and a large number of ready-made and shared parts of Rover P-3 models were used to save costs.

At the same time, a simple car body structure and a large number of aluminum car body designs were adopted to overcome the iron-deficient environment at that time, and the advantages of aluminum’s non-corrosion also made the car more durable. This utility vehicle is mainly used as a farm vehicle, so it is mainly designed to mount various agricultural tools. At the auto show in the spring of 1948, Land Rover agricultural trucks shined brilliantly, and an accidental inspiration made them one of the best brands in the 4X4 world!

Land Rover Important Time Events

In 1904, Rover began to produce cars.

Land Rover was born in 1948 and is a brand of Rover.

In 1966, Rover Company merged and became the Rover-Department of Leland Company.

It was acquired in 1988.

In 1989, it was officially renamed as Rover Group.

In 1990, we cooperated with Japanese companies in technology and capital.

In 1994, it was taken over by German BMW.

In March 2000, Land Rover and Land Rover were acquired to purchase all the four-wheel drive products of Land Rover, including Discovery,Freelander and Defender.

On July 22nd, 2005, it successfully acquired British MG Rover Automobile Company and its production division, which initiated the acquisition of famous foreign automobile companies by China enterprises. The merged company was called Nanjing Co., Ltd..

On March 26th, 2008, it invested $2.3 billion to acquire its Jaguar and Land Rover brands, which caused a shock in the international car world.

The birth of

In the 1960s, the designers of Land Rover believed that a car that paid attention to road driving performance and had comfort would be more favored by the market. So they started the research and development of "100-inch Station".

The gestation process of Land Rover Range Rover is slow and has been repeatedly tested and scrutinized. However, after polishing in the womb, it was extraordinary just after birth.

In 1950s, Rover had planned to add a new model, RoadRover, which was adopted between cars and off-road vehicles. However, in the end, this concept was not formally produced except for a number of concept models. It was not until the mid-1960s that it was put into practice. In July, 1970, RangRove appeared. It was equipped with Rover 3.5-liter V8 engine. At the same time, the original Land Rover’s steel plate suspension was replaced with a long-stroke spring, and the four-wheel drive was still adopted. In addition to its superior off-road ability, the road driving performance and comfort were greatly improved.

On June 17th, 1970, Land Rover Range Rover was officially born.

First Generation Land Rover Range Rover (1970-1994)

The Second Generation Land Rover Range Rover (1994-2001)

The Third Generation Land Rover Range Rover (2001-2012)

Fourth Generation Land Rover Range Rover (2012- present)

In 1982, Land Rover launched a four-door Range Rover, and the interior was also changed. After redesign and application of luxury materials, the Range Rover became a pure luxury off-road vehicle.

From the beginning, the comfort of Land Rover Range Rover was better than that of the same period. After years of development, luxury and comfort were integrated into the model genes. I have to admit that the Land Rover Range Rover is one of the best luxury cars in the world, and it is definitely a legendary model.

The competition in the domestic medium-sized car market has always been fierce, even in the pure electric market, and all manufacturers are on stage after you sing. As one of the leading players of its own brand, SAIC Roewe still has a blank in this market. In order to occupy the market as soon as possible, Roewe launched a brand-new model-Roewe D7. As the first model of Roewe’s brand-new new energy product sequence "D family", its overall design creates a young and avant-garde visual effect, and both pure electric and plug-in hybrid versions also enrich consumers’ choices. So what is the performance of Roewe D7 in terms of practicality? This issue of Daily Practical Test Report will reveal the answer for you.

Test vehicle: 2023 Roewe D7 EV 610km Rear Drive Ultimate Edition.

Official guide price: 176,800 yuan

I. Functional configuration test link

The 2023 Roewe D7 EV car is not equipped with the traditional one-button start button. After unlocking and entering the vehicle, you can start the vehicle by stepping on the brake, and then you can move forward with gear.

The trunk of the 2023 Roewe D7 EV supports remote key and outside opening, but it does not support inside opening, so there is still room for improvement.

The opening switch of the engine room cover is located at the lower left of the front of the driver’s seat. When opening the engine room cover, you need to pull the handle twice, and then go outside the car and lift the front engine cover. After opening, it was found that the car was equipped with double hydraulic rods, which made the overall opening and closing easier and had good support.

For consumers, the height of the threshold from the ground determines the convenience of getting on and off to a certain extent. According to the measured results, the threshold height of the 2023 Roewe D7 EV is 400mm from the ground, which ensures the convenience of getting on the bus.

Second, the comfort configuration test link

In terms of seats, the main driving seat of the test model supports four groups of memory functions. At the same time, the front seats support the heating function, and the main driver’s seat also supports the ventilation function, so the comfort performance is worthy of recognition.

In the main driver’s seat test, the distance between the front end and the rear end of the driver’s seat of the 2023 Roewe D7 EV is 260mm, and the seat has a long adjustable stroke, which is at the middle and upper reaches of the same level and can meet the needs of most drivers.

The multi-function steering wheel of the 2023 Roewe D7 EV supports manual up and down+front and rear adjustment, with an adjustable range of 50mm, which is at the middle and upper reaches of the same level; The up-and-down adjustable angle is 10, which is at the average level of the same level.

The rear seat of the 2023 Roewe D7 EV is equipped with three independent headrests, all of which can be adjusted up and down. The overall shape of the headrest on both sides is relatively wide, and the area of the headrest in the middle is moderate, which can effectively support the head of the rear row personnel.

The central armrest of the 2023 Roewe D7 EV adopts a fixed design, which does not support position adjustment. However, due to its large area, the driver’s elbow can easily lean on it in normal driving posture.

Third, the multimedia configuration test link

In terms of in-vehicle USB interface, the test vehicle is equipped with two USB Type-A and one USB Type-C interfaces in the front row, one USB Type-A and one USB Type-C interface in the front row penetrating storage compartment, and one USB Type-A in the rear of the inner rearview mirror. In the rear row, the car is equipped with a USB Type-A interface, which is located under the air outlet of the rear air conditioner.

At the same time, we tested the voltage and current of USB interface, and the voltage and current of the front interface were 5.08V and 0.46A respectively. The voltage and current of the rear interface are 4.96V and 1.85A respectively. In addition, the car is equipped with a 12V power interface above the USB Type-C interface in the front row, which is convenient for charging other devices in the car.

With the increasing popularity of smart cars, more and more models are equipped with intelligent voice assistants. For the "intelligent voice system", we judge the performance of the voice interaction system in terms of voice recognition rate, response speed and controllable functions through the following four segments of fixed speech.

1. I’m a little cold/I’m a little hot

2. Open the window/main driving window/sunroof.

3. I want to listen to "XXXX" (the name of the song)

I’m going to Lunyang Building.

During the test, as long as you say "Hello Zebra", you can wake up the voice system. After saying the above fixed words, the system can effectively identify and perform related actions, and the response is more sensitive. In addition, the car also supports continuous voice dialogue and can execute instructions in sequence. During the test, it was found that when executing multiple instructions, the system occasionally got stuck or missed, but in general, the function performance was still very strong.

Fourth, the space configuration test link

As a space test that is closely related to consumers, in the previous test drive article "Main Comfort Experience Test Drive 2023 Roewe D7 EV", we have already experienced its space, and this time we will evaluate the storage space and its convenience from the aspects of daily life.

For the test of the space used in the car, it is only for the space within reach of the front row, excluding the space that needs to be opened such as the glove box and the central armrest box. The test method is to put all the following fixed items in each storage space in the front row, and judge the performance of the vehicle storage space through the placement of the fixed items. The fixed items selected for the test are: 2 bottles of mineral water with normal size, 1 large-screen mobile phone, 1 lipstick, 1 satchel, 1 pair of sunglasses, 1 folding umbrella and 1 pack of paper with normal size.

According to the actual measurement, the above-mentioned fixed items can be reasonably placed in the storage spaces in the front row. The 2023 Roewe D7 EV has been hollowed out under the central passage in the front row, resulting in a very large storage space, which can be used for placing bags of regular size. In addition, the front and rear sides of the car cup holder are equipped with storage compartments for placing small items. It is worth mentioning that the interior of the vehicle is also equipped with glasses cases, and the bottom is also treated with flannel, with thoughtful details.

The interior space of the trunk of the 2023 Roewe D7 EV is regular, and the space can be further expanded after the rear seats are put down, which shows excellent practicality. For the basic value of the trunk, we also measured it, and the opening width is 1100mm；; The opening length is 450mm；; The depth of trunk is 1200mm；; The vertical height between the trunk platform and the inner roof is 470 mm.

V. Safety Configuration Testing Link

In the front and rear vision test of the vehicle, all the seats in the vehicle have been adjusted to the lowest state, and the measured data have some deviations from those when the driver is in normal use, which is for reference only.

In the test of the front field of vision, we use the pile bucket with a height of 70cm as a reference, and then adjust the distance between cars until the upper edge of the pile bucket can be seen in the main driving position. After testing, the final measured data of the pile bucket and the front of the car is 1.5m, which is at the upstream level among the tested vehicles of the same class.

In the rear vision test, the pile bucket is still fixed, and then the vehicle is moved until the upper edge of the pile bucket can be observed. The distance measured in the rear vision is 21.3m, which is at the downstream level in the same class of tested vehicles.

When testing the visual range of the exterior rearview mirror, firstly, let the tester stand at 10m vertical to the left and right rearview mirrors respectively, and then start to move to the left and right sides until it appears at the outermost edges of the rearview mirrors on both sides, and measure the lateral distance. Then, through formula calculation, the included angle of the rearview mirror field of view can be obtained. The larger the angle, the smaller the blind area of the rearview mirror, and the larger the blind area of the rearview mirror.

The 2023 Roewe D7 EV exterior rearview mirror has a moderate area, and neither side is equipped with double curvature lenses. The field of vision of the left exterior rearview mirror is 23.2, and that of the right exterior rearview mirror is 18.3. The left and right fields of vision are at the middle and lower reaches of the same level.

During the test, the reversing radar can sense the rear object at 1.5m, and the distance of continuous buzzer stage is 0.34m. Referring to the previous test experience, the closer the continuous buzzer stage is to 0.25m, the closer it is to daily use habits. Judging from the measured data, there is still a gap between the distance of the continuous buzzer of the test vehicle and the test experience value.

The 2023 Roewe D7 EV is equipped with a 360-degree panoramic image system, which displays very clearly, and also supports 3D viewing and chassis perspective functions, which further facilitates the driver’s control and prediction when parking. In addition, the vehicle radar display interface will also display the distance from the rear object, and when the distance is too close, the driver will be prompted to stop.

In daily use, vehicles often turn or turn around. At this time, the steering flexibility of vehicles is very important. Knowing the width of the road needed for the car to turn around in the same place can help you know fairly well, so as to avoid the occurrence of dangerous situations such as rubbing. After the actual measurement, the minimum road width of the test vehicle is 9.8m, which is at the average level of the same level.

In addition to the main driver’s seat, the 2023 Roewe D7 EV has interior handles above the other three doors. Handle in the car is necessary for people with mobility difficulties, and it can also play a certain auxiliary role for passengers’ riding safety on bumpy roads.

Sixth, endurance test

In the actual road test, the apparent endurance of the test vehicle before starting is 271km. After starting the vehicle, turn on the air conditioner and warm air, pass through the city ring road and the city center, and drive at an average speed of 50 2 km/h, and there are no congested sections in the whole process. After arriving at the destination, the total mileage of the vehicle increased by 27km, the cruising range of pure electric vehicle decreased by 49km, and the average cruising range consumed per 1km was about 1.8km.

In addition, we also tested the charging efficiency. It was measured that the battery capacity increased from 42% to 46%, the battery capacity increased by 4% and the cruising range increased by 27km after charging with the fast charging pile for 10 minutes. It is estimated that the time it takes to fully charge is slightly different from the estimated time of the system.

Summary:

Through the test, it can be found that the overall performance of the 2023 Roewe D7 EV is worthy of recognition. In particular, multiple storage compartments in the car can hold all the test items, which is more convenient for daily use. In addition, the car’s voice interaction ability is also very strong, the response and execution speed is fast, and the intelligent performance is excellent. However, there is a big blind spot in the rear view distance of the interior rearview mirror and the view range of the left/right exterior rearview mirror. At the same time, there is a gap between the continuous buzzer of the rear radar and the test experience. Generally speaking, the performance of the 2023 Roewe D7 EV will be even better if the details are slightly improved.

Du Ping, Executive Deputy Director of National Information Center.

Tian Jinchen, Director of the Western Department of the National Development and Reform Commission.

　　CCTV News (Reporter Ren Jia):On the morning of October 28th, the new book "Belt and Road Big Data Report (2016)" was released in Beijing, and Du Ping, executive deputy director of the National Information Center, released the report. Tian Jinchen, head of the comprehensive team of the Office of the Leading Group for Promoting the Construction of the Belt and Road, and director of the Western Department of the National Development and Reform Commission, attended the conference and delivered a speech. This is the first comprehensive annual report in China to comprehensively evaluate the progress and effectiveness of the Belt and Road construction by using big data technology. It is also the first time in the world to evaluate the progress and effectiveness of the Belt and Road construction in countries and regions along the Belt and Road and domestic provinces and cities.

　　The report was directed by the Office of the Leading Group for Promoting the Belt and Road Construction, compiled by the Belt and Road Big Data Center of the National Information Center and published by the Commercial Press. Yizamp Technology Group provided major data and technical support for the report, which is the world’s leading big data and cross-border trade and financial group. The report brings together about 300 billion pieces of data from major international and domestic statistical agencies, news websites, social media, forums and other Internet channels, involving over 5PB of original data, covering 64 countries and regions along the Belt and Road Initiative. From the international and domestic perspectives, the report constructs a comprehensive evaluation system for the development effectiveness of the Belt and Road Initiative, including country cooperation index and provincial and municipal participation index, and discusses the hot topics of the Belt and Road Initiative such as international capacity cooperation, regional cooperation, RMB internationalization and cross-border electronic commerce.

　　International cooperation: Russia ranks first.

　　The "Country Cooperation Index" developed in this report is a series of evaluation indicators and evaluation methods built around the five major cooperation priorities of "Belt and Road". Specifically, it quantitatively evaluates the country cooperation between China and more than 60 countries along the "Belt and Road" from five dimensions: policy communication, facility connectivity, trade smoothness, capital financing, and popular support, and forms a comprehensive evaluation index.

　　The evaluation results show that among the 64 countries along the Belt and Road participating in the evaluation, 32 countries belong to "to be strengthened", 17 countries belong to "gradual expansion", 13 countries belong to "rapid advancement" and 2 countries belong to "deep cooperation", among which Russia, Kazakhstan, Thailand, Pakistan and Indonesia rank in the top five.

　　The evaluation results show that the effect of policy communication between China and countries along the Belt and Road is good as a whole, political mutual trust has been significantly enhanced, and communication facilities have basically reached "interconnection", while the level of facility connectivity has obvious regional characteristics. Thailand, Singapore, Malaysia and China have the best air connectivity; Russia, Kazakstan, Mongolia, Myanmar and China have the best energy facilities. Pakistan, Laos, Russian Federation, Kazakstan and Mongolia have the best cross-border communication facilities with China. In terms of trade and investment, China’s foreign investment cooperation is relatively smooth, and the national cooperation projects and projects have a good momentum of expansion. China’s investment cooperation with Russian, Mongolian and Southeast Asian countries has achieved remarkable results. At the same time, the report also points out the aspects that China still needs to improve in international cooperation. At present, the growth rate of China’s foreign trade has slowed down, and the level of financing has obvious differences among countries. Only with Southeast Asian countries, the construction of financial support environment is relatively good, and other regions need to be strengthened. Although the construction of people’s hearts has achieved remarkable results, it needs to strengthen in-depth and sustained information communication and more targeted public opinion propaganda.

　　New book "Belt and Road Big Data Report (2016)"

　　Provincial and municipal participation: Guangdong ranks first in the country.

　　The "Participation Index of Provinces, Regions and Cities" developed in the report is a systematic evaluation model and method system around the three levels of "foundation-action-effect", which comprehensively evaluates the participation of 31 provinces (autonomous regions and municipalities) in the "Belt and Road" construction and its implementation effect. The results show that 5 provinces (autonomous regions and municipalities) are at a "low" level, 9 provinces (municipalities) are at a "medium" level, 12 provinces (autonomous regions and municipalities) are at a "high" level, and 5 provinces (autonomous regions and municipalities) are at a "high" level, including Guangdong, Zhejiang, Shanghai, Tianjin, Fujian, Jiangsu, Shandong and Tianjin.

　　Through the collection and analysis of data, it is concluded that there is a big gap in the participation level of the "Belt and Road" construction among provinces (autonomous regions and municipalities). The provinces and municipalities in the eastern coastal areas scored the highest in the comprehensive evaluation, while the northwest and southwest regions need to be strengthened.

　　At the same time, the evaluation results of the report show that since the "One Belt, One Road" initiative was put forward, the "One Belt, One Road" policy environment has been optimized, the management system has been basically sound, policy documents have been issued one after another, the financial guarantee has been gradually strengthened, and the supporting construction of related facilities has been accelerated. In the past three years, the construction of parks abroad has gradually increased, and the level of connectivity of railways, aviation, highways and ports has been continuously enhanced. In terms of foreign investment, all localities have a high enthusiasm for participating in foreign economic and trade cooperation, and the momentum of foreign direct investment is good. 81.7% of provinces and cities have foreign direct investment of more than 1 billion US dollars, and 77.42% of provinces and cities have foreign direct investment growth rate of more than 20%. All localities actively participate in overseas project construction, with Shandong, Yunnan, Guangdong, Sichuan and Beijing ranking first.

　　It can be seen from the report that the comprehensive influence of participating in the "Belt and Road" construction has begun to appear. Xinjiang, Fujian, Guangdong, Shanghai and Beijing rank among the top five in domestic influence, while Shanghai, Henan, Beijing, Guangdong and Zhejiang rank among the top five in foreign influence.

　　The report also gives suggestions on the parts that need to be improved in the construction of the "Belt and Road": the construction and utilization rate of supporting facilities need to be improved, and the comprehensive benefits need to be improved; The potential of foreign trade and economic cooperation needs to be further developed, and the participation of western provinces and cities needs to be strengthened.
