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.
