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.

Beijing BJ30, which focuses on "light off-road" positioning, meets consumers' dual needs for off-road performance and driving pleasure. It has a high cost-effectiveness and practicality among models of the same level. Since its launch, it has quickly become a popular model in the compact SUV market segment. After three years, the new Beijing BJ30 has been upgraded and launched. In addition to continuing the advantages of the old model in terms of passability, it also adopts a more fashionable design language and a more complete intelligent configuration, and introduces a hybrid system, which greatly improves fuel economy. According to the data from the car quality network, as of press time, the total number of complaints about the new Beijing BJ30 Magic Core Electric Drive Edition since its launch is only 2, and its reputation has performed well in the short term. So, can the new Beijing BJ30 Magic Core Electric Drive Edition 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 new Beijing BJ30 Magic Core Electric Drive Edition 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/field of 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, the average gap of all parts of the new Beijing BJ30 Magic Core Electric Drive Edition is controlled within 4mm. However, the average gap at the connection between the right front fender and the engine hood is relatively high, but it has little effect on the final test results.

In the paint film level test, the test results show that the average paint film thickness of the new Beijing BJ30 Magic Core Electric Drive Edition is about 130.1μm, which reaches the standard value of high-end cars (120μm-150μm) in terms of data. From the test data of key parts, the paint film thickness of the rear doors and roof on both sides exceeds the standard value of mid-range cars, and the paint film thickness of other parts reaches or exceeds the standard value of high-end cars. In addition, the paint film thickness of the right front fender and front door is significantly higher than that of the left side, which may be related to the paint repair.

In the in-car air quality test, the vehicle was placed in an internal ground parking lot with fewer vehicles. The actual formaldehyde content in the new Beijing BJ30 Magic Core Electric Drive Edition was measured to be 0.08mg/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 and implemented on March 1, 2012.

In the static noise test, the measured noise value of the new Beijing BJ30 Magic Core Electric Drive Edition in the static state is 36.1dB. Since the evaluation car is equipped with a hybrid system, the engine does not work by default in the static state after starting, so the noise of the engine at 2000 rpm and 3000 rpm cannot be tested.

In the air conditioning noise test, the test instrument is first placed about 10cm away from the air outlet, and then the air volume is adjusted from small to large, and the noise value at the driver's position is measured at different gears. According to actual measurements, the air conditioning adjustment of the new Beijing BJ30 Magic Core Electric Drive Edition is divided into 8 gears. When the highest gear is turned on, the noise value is 75.2dB, which is slightly higher than the same level models tested before.

In the static in-vehicle vibration test, under both conditions, the vibration value at the steering wheel of the new Beijing BJ30 Magic Core Electric Drive Edition was always 0, and the vibration values ​​of the front and rear seats were also at a low level and remained unchanged, with minimal physical sensation.

In addition, we also tested the parking radar, lighting/vision, control system, tires, sunroof, seats, and trunk. After testing, the driver's seat of the new Beijing BJ30 Magic Core Electric Drive Edition has a large adjustment range and can adapt to drivers of different sizes. The evaluation car is equipped with Giti Comfort F50 series tires, which use soft noise reduction technology to effectively reduce noise, while having lower rolling resistance and shorter wet braking distance, bringing a pleasant and safe driving experience. The tire specification is 235/60 R19. Relatively speaking, due to the small size of the rear windshield, the rear blind spot is large, and the length of the rear seat cushion is short, which needs to be optimized.

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 evaluation of external experience, the new Beijing BJ30 Magic Core Electric Drive Edition retains the classic five-hole grille design, and integrates the headlights with the grille, exuding a stronger sense of fashion. The side strengthens the "square box" shape, and with the convex black wheel eyebrows, it highlights the positioning of a hard-core SUV. In terms of details, the large area of ​​black guard plates around the body can effectively prevent scratches when off-roading. In addition, the high-profile tires also help to improve the ground clearance and driving comfort of the vehicle. What is slightly insufficient is that the ECU computer in the engine compartment is relatively forward, and the safety factor is low; in addition, the rear wiper is small in size and the wiping area is very limited.

In the internal experience evaluation, the new Beijing BJ30 Magic Core Electric Drive Edition adopts a simple design style as a whole, and creates a strong fashion atmosphere through a patchwork layout and unique color matching. In terms of details, the central control area uses a yacht-like gear lever and a turbine-shaped ATS all-terrain control knob, which looks quite delicate. Although the instrument panel uses a large area of ​​plastic material, it brings a good visual texture through fine texture processing.

Thanks to the considerable body size and straight roofline, both front and rear passengers can get good space. In terms of storage, the storage compartments in the car are reasonably laid out and have a relatively regular shape, which can meet the needs of daily car use. A storage compartment with a large volume is provided under the front central channel, which is convenient for placing larger items. The central armrest box adopts a double-layer design with good internal depth, and it also has air-conditioning vents, which can be used as a heating and cooling box. Relatively speaking, there is only one USB Type-C charging port in the back row, which is relatively small in number and has average compatibility, and needs to be improved.

The 14.6-inch central control screen is equipped with a Qualcomm Snapdragon 8155 chip. The car system UI design is simple and refreshing, and the operation is relatively smooth. The car interface adopts a multi-page card layout, and a permanent menu bar is provided on the left. You can customize the shortcut function buttons according to personal needs, which is very convenient to use. In terms of human-computer interaction, the voice system supports dual-zone wake-up recognition, continuous voice recognition and other functions. The actual voice system can recognize commonly used fuzzy semantics, but the response speed and accuracy need to be improved.

The test vehicle is equipped with a hybrid system consisting of a 1.5T engine and dual motors, and its comprehensive performance indicators are comparable to those of a 3.0T engine. Due to the small battery capacity, the entire power system is closer to a traditional HEV. The motor is mainly used during starting and rapid acceleration, and the vehicle has a good power response, making the driving experience very brisk.

Compared with traditional HEV, this hybrid system has a higher tolerance, supports pure electric driving at speeds below 70km/h, and provides excellent fuel economy performance. When entering the highway, the engine can also drive the vehicle directly, bringing a more continuous acceleration feeling.

Due to the need to take off-road scenarios into consideration, a certain amount of empty space is left at the beginning of the brake pedal. By continuously pressing the pedal, sufficient and linear braking force can be obtained, giving people enough confidence. However, when braking with full force, the higher center of gravity of the vehicle body will still affect the comfort of the passengers, and the vehicle nodding phenomenon is more obvious.

The power steering is set to be relatively light, the steering wheel has a slight damping feeling, and the electronic flavor is slightly strong. The advantage of this setting is that it can improve driving comfort on the one hand, and it is also conducive to vehicle control when off-roading on the other hand. But the disadvantage is that the road feel is not strong, and you need to hold the steering wheel firmly when driving at high speed.

Although it adopts the design of a hard-core SUV, the chassis setting of the evaluation car still adheres to the comfortable style of urban SUVs, and the suspension system can effectively absorb the vibration of the road. However, when turning at high speed or changing lanes continuously, the body roll is more obvious, which is obviously not suitable for intense driving.

The test car is equipped with a Level 2 assisted driving system that supports automatic lane change. The acceleration and deceleration during full-speed adaptive cruise following are relatively natural, and the following distance supports multi-gear adjustment. The closest gear has a large gap with the front car, making it easy for other social vehicles to cut in.

Summarize:

Based on the above test results, it is concluded that the overall performance of the new Beijing BJ30 Magic Core Electric Drive Edition in terms of objective data and subjective feelings has met the expectations of the expert jury. In terms of objective data, the overall performance of the paint film thickness is good, but there is still room for improvement in the seam process and paint film spraying uniformity of individual parts. In terms of subjective feelings, the square body shape and abundant power system provide excellent passing performance, and the rich car machine functions and perfect auxiliary driving system also bring a good intelligent experience, but problems such as slow voice response speed and unreasonable cruise system following distance still need to be optimized. Overall, the commercial performance of the new Beijing BJ30 Magic Core Electric Drive Edition is at the middle level among the tested models of the same level.
