as a leading third-party automobile quality evaluation platform in china, chezhi.com has launched the "new car commodity evaluation" column based on a large number of automobile product test samples and scientific data models. every month, senior evaluators use professional equipment to conduct systematic testing and evaluation of several models that have been on the market in china for less than two years and have a mileage of no more than 5,000 kilometers, using objective data and subjective feelings to comprehensively display and analyze the overall commodity level of new cars in the domestic automobile market, and provide consumers with objective and true opinions when purchasing vehicles.

for 99,800 yuan, you can buy a mid-size car equipped with plug-in hybrid power. this is the byd qin l, which is nicknamed "the king of volume" by many netizens. according to the data from the auto quality network, as of press time, the 2024 byd qin l has received 52 complaints since its launch, and its reputation has been relatively stable in the short term. so, can it continue its existing reputation? will there be some new problems that are difficult for ordinary consumers to find? this issue of "new car commodity evaluation" will clear the fog for you and restore a real 2024 byd qin l through two dimensions: objective data and subjective feelings.

1. objective data

this project mainly conducts field tests on 12 items including body craftsmanship, paint film level, in-car air quality, vibration and noise, parking radar, lighting/vision, etc., to comprehensively and intuitively display the commercial performance of the new car in the form of objective data.

in the body craftsmanship test, 10 key parts of the vehicle were selected, and 3 key points were selected for each key part to evaluate the uniformity of the gaps in each key part. from the test results, most of the gap averages are controlled within a reasonable range, only the value at the connection between the front fender and the left front door is slightly higher, but it has little impact on the overall results, and the performance is worthy of recognition.

in the paint film level test, the test results show that the average thickness of the paint film of the 2024 byd qin l is about 116.9μm, which exceeds the standard value of mid-size cars (≥90μm). judging from the test data of various key parts, the paint film thickness of the roof is low and does not reach the standard value of mid-size cars. the test values ​​of the engine hood, right front fender, left front door and left/right rear fenders all reach the standard value of high-end cars (120μm-150μm). it can be seen that the paint film spraying thickness of the whole vehicle is acceptable, but the spraying uniformity can still be improved.

in the in-car air quality test, the vehicle was placed in an internal ground parking lot with fewer vehicles. the actual measured formaldehyde content in the car reached 0.02mg/m³, which is in line with the relevant standards in the "guidelines for passenger car in-car air quality evaluation" (national standard of the people's republic of china gb/t 27630-2011) jointly issued by the former ministry of environmental protection and the general administration of quality supervision, inspection and quarantine on march 1, 2012.

in the static noise test, the evaluation car has excellent isolation from external noise when stationary, and the measured noise value inside the car is 33.8db. at the same time, because it is equipped with a plug-in hybrid system, the engine does not work after the vehicle is started, there is no obvious noise inside the car, and the engine does not work when the accelerator pedal is pressed, so the noise at 2000 rpm and 3000 rpm cannot be tested.

in the air conditioning noise test, the test instrument was first placed about 10cm away from the air outlet, and then the air volume was adjusted from small to large, and the noise value at the driver's position was measured at different gears. according to actual measurements, the air conditioning adjustment of the evaluation car is divided into 7 gears, and the noise value was measured at the highest gear of 69.4db, which is slightly higher than the same level models tested previously.

in the static in-car vibration test, the steering wheel vibrates at 0.2mm/s in both static and loaded states after starting. the seats vibrate at 0.2mm/s and 0.3mm/s in both states, which shows little impact on comfort, ensuring the comfort of passengers.

in addition, we also tested the parking radar, lighting/vision, control system, tires, sunroof, seats, and trunk. after testing, we found that although the evaluation car is equipped with an openable panoramic sunroof, the opening area is small. at the same time, as a top-of-the-line model, it does not provide an electric trunk. in addition, the evaluation car is equipped with 18-inch wheels, matched with chaoyang brand su318a+ model tires, which have the characteristics of fuel saving, wear resistance and strong wet grip. the specific specifications are 225/50 r18.

2. subjective feelings

this project is conducted by multiple judges to conduct subjective evaluations on the actual static and dynamic performance of the new car. the static aspects include the exterior, interior, space and human-machine interaction; the dynamic aspects include acceleration, braking, steering, driving experience and driving safety. finally, the total score is given by comprehensively referring to the subjective evaluation opinions of each judge, reflecting the actual performance of the new car in terms of commerciality from the perspective of subjective feelings.

in the external experience evaluation, the evaluation car adopts the "new national trend dragon face aesthetics", with narrow and sharp headlights, a front grille with matrix chrome decoration, and upturned "dragon beard" led daytime running lights, which looks quite majestic overall. in the external configuration test, it was found that the keyless entry function only supports the front row, and the induction unlocking function is not provided. if you want to take something without opening the front door, you can only take out the key to unlock it, which is relatively troublesome.

in the internal evaluation, the interior design of the evaluation car was inspired by chinese landscape painting, and the black high-gloss trim is an integrated design, which looks more majestic. the 15.6-inch floating central control screen still supports rotation, which is already a traditional skill of byd's models. at the same time, the air-conditioning outlets on both sides of the front row are designed with upper and lower layers, but the wind direction cannot be adjusted independently, and the decorative significance is greater than practical. at the same time, the front middle outlet is more difficult to adjust, which shows that the details need to be improved.

in terms of space, the front and rear seats are spacious and comfortable. the storage space is also impressive. the front central channel adopts a double-layer design, and large-volume carry-on items such as satchels can be placed below. the rear handle is the same as the front handle, which can be used as a storage slot. the only drawback is that the rear central armrest only provides two cup holders and is not equipped with a storage slot, which slightly affects the storage capacity.

in terms of human-computer interaction, just say "hello, xiaodi" and the car computer will respond quickly. the voice system supports controlling hardware functions such as windows, sunroofs and air conditioning, but only in the front dual-tone zone. in addition, the system also provides functions such as no wake-up word, see and speak, and continuous voice recognition, and the functional experience is in line with the current mainstream.

the evaluation car is equipped with the fifth-generation dm system, which consists of a 1.5l naturally aspirated engine + a front single motor. the maximum power of the engine is 74kw, the maximum torque is 126n·m, and the electric motor is divided into two adjustments. the total power of the 80km version is 120kw, and the total torque is 210n·m; the evaluation car is the 120km version, the total power of the electric motor is 160kw, and the total torque is 260n·m. in actual experience, even if the battery is insufficient, the motor can output power at the starting stage. as the speed increases, the engine begins to intervene. the movement when switching between the two power is slight and not easy to detect. the power performance is similar to that of pure electric vehicles. the starting stage is light and linear, and very comfortable.

the braking system can release significant braking force with a light press, and the overall performance is also relatively linear and easy to control. in addition, during emergency braking, the braking force is also sufficient, and the second half of the brake pedal is relatively tight, which can give the driver more direct feedback.

the steering system has moderate strength, and the strength when returning to the center is relatively natural, with excellent hand feel. at the same time, although the directionality and flexibility of the front of the car are not very sensitive, it is smooth to use. a small amount of free space can give the driver a higher degree of tolerance, making driving easier.

in terms of driving experience, the test car is equipped with an independent suspension combination, and the tuning style is obviously biased towards comfort. when driving on urban roads, most road bumps can be effectively resolved, ensuring ride comfort. when passing through larger potholes such as speed bumps, the longitudinal vibration amplitude in the car will increase significantly, but fortunately it is handled cleanly and neatly without unnecessary swinging.

the test car is equipped with a variety of active and passive safety functions, and is equipped with a level 2 assisted driving system that can achieve full-speed adaptive cruise control. the acceleration and deceleration during the following process are moderate, but the lane centering function is average, and occasionally there will be a situation of "drawing a dragon" in the lane.

summarize:

based on the above test results, it can be concluded that the 2024 byd qin l has met the expectations of the expert jury in terms of both objective data and subjective feelings. in terms of objective data, the body craftsmanship and paint film thickness are satisfactory, but the uniformity of the paint film spraying is relatively general, and there is room for improvement. in terms of subjective feelings, the fifth-generation dm power technology has a very outstanding performance in terms of acceleration experience and fuel consumption level. if the processing of interior details can be improved, i believe it will bring users a better experience. on the whole, the commercial performance of the 2024 byd qin l is at the middle level among the tested models of the same level.
