in the domestic market, new energy vehicles are becoming more and more popular. according to the latest data, in august 2024, the retail penetration rate of new energy vehicles in china's auto market has reached 54%. faced with the continuous increase in market share, car companies are also continuing to increase their exposure to the new energy market. judging from market feedback, new energy medium and large vehicles are becoming more and more popular because models of this level perform well in terms of space, comfort and practicality. in previous product evaluations of new cars, we have tested a number of pure electric medium and large vehicles. today we have selected four very value-for-money models and compared them with various test data to see which car has the best commercial performance. performance is more comprehensive.

1. body craftsmanship

in the body process, judging from the test results, the gap uniformity of each test part of the 2024 bmw i5 xdrive m60 (hereinafter referred to as the bmw i5) performed relatively well, and the average value of most gaps was controlled within a reasonable range. in comparison, the average gap at the connection between the left and right rear fenders and the trunk of the 2024 changan qiyuan a07 pure electric true fragrance edition 710 flagship model (hereinafter referred to as changan qiyuan a07) has a certain impact on the test results. .

2. paint film level

in terms of paint film level, judging from the test results, the overall performance of changan qiyuan a07 is good. the average thickness of the vehicle's paint film reaches the standard value for high-end cars (120μm-150μm), and except for the roof, the paint film on most key parts the difference in average thickness is small, and the uniformity of paint film spraying on the entire vehicle is better than that of the other three models. in comparison, the performance of the bmw i5 m60 is somewhat unsatisfactory. the average thickness of the vehicle's paint film is about 76.5 μm, and the data level does not reach the standard value for mid-level cars (≥90 μm).

3. air quality inside the car

in the in-car air quality test, the four models all complied with the "passenger car in-car air quality evaluation guidelines" jointly issued by the former ministry of environmental protection and the state administration of quality supervision, inspection and quarantine (people's republic of china relevant standards in the national standard of the republic of china gb/t 27630-2011).

4. noise inside the car

in the car noise test, in addition to testing the noise in the car when it is stationary, the test instrument will also be placed about 10cm away from the air conditioner outlet, and then the air volume of the air conditioner will be increased from small to large, and the air volume at different levels will be measured. air conditioning noise level below the driver's seat.

according to actual measurements, in the stationary state, the interior noise of the changan qiyuan a07 and bmw i5 reached the lowest value of 30db, which is the lowest value of the test instrument. since all four vehicles use pure electric drive, the noise transmitted from the electric motor into the car is negligible when the vehicle is stationary after starting.

in the air-conditioning noise test, the air-conditioning adjustment of the bmw i5 is divided into 5 levels. the noise value at the lowest level is better than the other three models. the air conditioning adjustment of the 2024 zhiyi l6 max long-range version (hereinafter referred to as zhiyi l6) is divided into 11 levels. when the highest gear is turned on, the measured noise value is 61.5db, which is the best performance among the four models.

5. static in-car vibration

in the static in-car vibration test, in the two states, except for the zhiji l6, the vibration value at the steering wheel of the other three models was always 0, which is a remarkable performance. in contrast, when the zhiji l6 is under load, the vibration values ​​of the driver's seat and passenger's seat increase significantly, but the actual body feeling is not obvious.

6. skylight

in the test for sunroofs, all four models were equipped with panoramic sunroofs that could not be opened. from a data perspective, dongfeng yipai eπ007 has the largest area and can bring considerable transparency to the passengers in the car.

7. control system

in terms of control systems, the steering wheels of dongfeng yipai eπ007, bmw i5 and changan qiyuan a07 are moderate in size, taking into account control stability and flexibility, while the diameter of the zhiji l6 steering wheel is on the small side. in terms of adjustment, changan qiyuan a07 and bmw i5 take the lead in up and down adjustable angles and front and rear adjustable distances respectively.

in terms of the width of the accelerator pedal, the width of the brake pedal, and the step difference between the brake pedal and the accelerator pedal, which affect the driving experience, the performance of the four models is relatively close, and the step difference is within a reasonable range. this design can prevent the phenomenon of mixing the accelerator and the brake pedal. , and at the same time, when driving in congested road conditions, frequent alternate pedaling of the feet will not make the driver feel tired.

in terms of footrests, the bmw i5 is made of metal, which has a good sense of quality. dongfeng yipai eπ007 and changan qiyuan a07 are both made of rubber, while the zhiji l6 is made of velvet, which is not very resistant to dirt.

8. seats

in terms of seat configuration, according to measured data, the main driver's seat travel adjustment range of dongfeng yipai eπ007 is large, which can meet the driving habits of most drivers.

in terms of seat cushion length, the front seat cushion length of the zhiji l6 is ahead of the other three models, while the rear seat cushion length of the changan qiyuan a07 is shorter and the ride comfort is average. in terms of the angle of the rear seat backrest, the bmw i5 performs well, followed closely by the changan qiyuan a07, both of which are more comfortable to ride.

in terms of raised height of the rear floor, dongfeng yipai eπ007 and changan qiyuan a07 maintain a flat rear floor; while the bmw i5 m60 has a higher raised floor, which will affect the comfort of the middle passenger to a certain extent.

9. trunk compartment

regarding the trunk, judging from the actual measurement data, the bmw i5 performed well in the maximum width test of the trunk, while the zhiji l6 performed better in the minimum width test of the trunk. in terms of trunk sill height, changan qiyuan a07 performs best. in terms of the trunk opening area, except for the bmw i5, the other three models all adopt a hatchback design, and the opening areas all perform well.

10. parking radar

in the radar induction test, based on existing test data, the four models performed differently. among them, the zhiji l6 rear radar has strong detection capabilities, with a maximum detection distance of 1.5m and good radar power performance. based on past test experience, the closer the continuous buzzing stage is to 0.25m, the closer it is to daily usage habits. judging from the actual measurement data, the bmw i5's rear radar continuously beeps to indicate that the distance is relatively close to the test experience value.

in terms of front radar, zhiji l6 also has the strongest detection capability, with a data level of 1.5m. in terms of distance prompts during the continuous beeping stage, the zhiji l6 is also closer to the test experience value than other models.

11. light vision

in the blind area test of the front view, we used a 70cm-high pile barrel as a reference object, and then adjusted the relative position of the vehicle until the upper edge of the pile barrel could be seen from the driver's seat. according to existing test data, zhiji l6 performs relatively well and has a smaller blind spot in the front field of view. in terms of rear vision, the performance of dongfeng yipai eπ007 is better than the other three models.

in the outside rearview mirror field of view test, the zhiji l6's left outside rearview mirror has a wider field of view, while the bmw i5's right outside rearview mirror has an excellent field of view.

summarize:

through the above comparisons, it is not difficult to find that the four value-for-money pure electric medium and large vehicles selected this time have all delivered satisfactory answers in terms of commerciality. among them, dongfeng yipai eπ007 performed well in terms of static in-car vibration; bmw i5 performed well in terms of interior noise; zhiji l6 performed well in the front view and left exterior rearview mirror field of view tests; changan qiyuan performed well a07 is relatively good in terms of paint film level. taken together, none of the four cars has obvious shortcomings in terms of commerciality, and consumers can choose according to their own needs.
