Commercial Evaluation of 2022 Beijing Benz C-Class New Cars

As a leading third-party vehicle quality evaluation platform in China, Vehicle Quality.com has launched the column "Commodity Evaluation of New Cars" based on a large number of automotive product test samples and scientific data models.Every month, for several models on sale within two years of domestic market, the mileage does not exceed 5,000 kilometers, through the two dimensions of objective data and subjective experience, senior evaluators use professional equipment to conduct systematic testing and evaluation to comprehensively display And analyze the current status of the overall commodity level of new cars in the domestic auto market, and provide consumers with objective and true opinions and references when purchasing vehicles.

The luxury mid-size car market has always been a battleground for military strategists. As more and more new and powerful models join in, established luxury brands are facing huge challenges.As one of the three major German luxury brands, Mercedes-Benz took the lead in launching a brand-new Mercedes-Benz C-Class in 2021.The new generation of Mercedes-Benz C-Class has been optimized through a series of details, the appearance has become more fashionable and refined, and the interior has almost completely copied the design of the family flagship S-Class, further enhancing the sense of luxury.According to the data of the car quality network, as of May 31, 2022, the cumulative number of complaints since the launch of the new-generation Mercedes-Benz C-Class was 40, and the complaint sales ratio was lower than the 2021 domestic passenger car annual complaint sales ratio of 30.9 per 10,000. , short-term word-of-mouth performance is worthy of recognition.So, can the new generation of Mercedes-Benz C-Class continue the existing quality reputation performance?Will there be some new problems that are difficult for ordinary consumers to discover?This issue of "Commodity Evaluation of New Cars" will clear the fog for you, and restore a real Mercedes-Benz C-Class through the two dimensions of objective data and subjective experience.

1. Objective data

This project mainly passes on-the-spot tests on 12 items of the new car in the form of objective data, including body craftsmanship, paint film level, interior air quality, interior noise, static interior vibration, parking radar, and lighting/vision. The orientation intuitively shows the performance of the new car in terms of commerciality.

In the body craft test, a total of 10 key parts are selected for the whole vehicle, and 3 key points are selected for each key part for measurement to evaluate the uniformity of the gaps in each key part.From the test results, the mean value of gap data in most parts of the 2022 Mercedes-Benz C-Class is at a relatively low level.However, there is process asymmetry at the connection between the trunk and the left and right rear fenders. The difference between the maximum and minimum gap values ​​is 1.1mm. It is unknown whether it is a test drive.The uniformity of the gap data in the rest of the parts is good, and the craftsmanship is basically satisfactory.

In the paint film level test, it can be found from the test results that the average thickness of the paint film of the 2022 Mercedes-Benz C-Class is about 133.9 μm, which reaches the standard value of high-end vehicles (120 μm -150 μm).Judging from the test data of various key parts, the average thickness of the paint film on the front door, rear door and rear fender exceeds the standard value of the premium car, while the average thickness of the paint film on the engine cover, front fender and roof only reaches the intermediate value of the car. Standard values, individual test points are even below 90μm.Overall, the coating thickness of the 2022 Mercedes-Benz C-Class is acceptable, but there is still room for improvement in the uniformity of the coating.

In the in-vehicle air quality test, the vehicle was placed in an internal ground parking lot with fewer vehicles. The actual measurement of the 2022 Mercedes-Benz C-Class did not detect formaldehyde, and the content of PM2.5 and other substances was also relatively low. It is fully in line with the "Guidelines for Air Quality Evaluation in Passenger Cars" jointly issued by the former Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China (National Standard of the People's Republic of China GB/T 27630-2011 ) in the relevant standards.

In the static noise test, the 2022 Mercedes-Benz C-Class performs well in the quietness of the car in a static state, and the test results have dropped to the lowest value of the test instrument of 30dB, which can almost be isolated from the external ambient sound.As the engine starts, the noise value introduced into the car shows a gradually increasing trend. When the engine is at 3000 rpm, the noise value introduced into the car is 58dB. Compared with other models of the same level, the noise value is higher.Compared with the noise values ​​in the following different environments, the 2022 Mercedes-Benz C-Class performs well in suppressing engine noise, and it hardly interferes with the drivers and passengers in the car under working conditions.

In the air-conditioning noise test section, first place the test instrument at a position about 10cm away from the air-conditioning outlet, then increase the air-conditioning air volume from small to large, and measure the noise value of the driver's position in different gears.According to the actual measurement, the air conditioning adjustment of the 2022 Mercedes-Benz C-Class is divided into 5 gears. When the highest gear is turned on, the measured noise value is 63.5dB, which is still in the range that can be tolerated by the human body and will not cause too much interference to the drivers and passengers.However, in the test, the expert jury found that the noise value reached 47.4dB in the starting gear of the air conditioner, which is slightly higher than that of the models of the same level tested before.

After actual measurement, in the idling state, the 2022 Mercedes-Benz C-Class has excellent suppression of vibration from the engine into the car. The vibration value of the steering wheel is 0, while the vibration value of the front and rear seats is relatively high.Under the load state, the vibration value of the steering wheel increases slightly, while the vibration value of the front and rear seats remains unchanged, and the body feeling is not obvious.

In addition, we also tested the parking radar, lights/vision, handling system, tires, sunroof, seats, trunk.After testing, the overall performance of the 2022 Mercedes-Benz C-Class has reached the level expected of a luxury brand. The steering wheel and driver's seat have a large adjustment range, and the length of the rear seat cushion and headrest have also been upgraded, and the ride comfort is excellent.In addition, the field of view of the exterior rearview mirrors on both sides is also at the leading level in the same class.However, the sunroof adopts a segmented design, the lighting effect is not as good as that of the panoramic sunroof, and the opening area is small.The rear floor has a large raised height, making it difficult for middle passengers to find a comfortable sitting position.

2. Subjective feelings

In this project, a number of reviewers conduct subjective evaluations of the actual static and dynamic performance of the new car.Among them, the static aspect includes four major parts: exterior, interior, space and human-computer interaction; the dynamic aspect includes five major parts: acceleration, braking, steering, driving experience and driving safety.In the end, the total score is given comprehensively with reference to the subjective evaluation opinions given by the reviewers, so as to reflect the actual performance of the new car in terms of commerciality from the perspective of subjective feeling.

In the external experience evaluation, the 2022 Mercedes-Benz C-Class has been affirmed by the expert jury in terms of lighting system, engine compartment materials and trunk configuration.The test model is equipped with intelligent digital LED headlights. In addition to providing conventional automatic headlights and adaptive high and low beam functions, it can also realize the planning of lighting solutions in advance according to satellite positioning.The engine compartment is supported by double hydraulic rods, and is equipped with stabilizer bars and guards, and the internal materials are also very solid.In addition to supporting electric opening, the trunk is also equipped with an induction function. The measured sensitivity is good and the operation is more convenient.However, the 2022 Mercedes-Benz C-Class is slightly inconvenient in terms of using mechanical keys, mainly because the keyhole is a hidden design, which is inconvenient to use, but for aesthetic reasons, it is understandable.

In the internal evaluation, the 2022 Mercedes-Benz C-Class adopts a design style similar to that of the new S-Class. The 11.9-inch vertical central control screen and the 12.3-inch full LCD instrument form a dual-screen system with a strong sense of technology.In terms of materials, it has reached the standard of luxury brands. The center console and door panel area are covered with a large area of ​​soft leather, supplemented by just the right black wood grain decoration, showing a full luxury texture.

The 2022 Mercedes-Benz C-Class provides 6 charging ports, which are evenly distributed in the front and rear rows. Although there are a large number of charging ports, they are generally compatible with devices due to the unified use of Type-C ports.In addition, although the front center armrest cannot be moved, due to its considerable length and width, it can provide sufficient support for the driver's elbows.

In terms of passenger space, the wheelbase close to 3 meters brings ample rear legroom, but relatively speaking, the rear head space is slightly cramped.In terms of storage space, the overall number of 2022 Mercedes-Benz C-Class has reached the mainstream level of the same level, but there is still room for optimization in some detailed designs, such as the location of the wireless charging pad for mobile phones in the front row is relatively hidden, and it is not convenient to take mobile phones; the interior of the center armrest box It is shallow and practical; in addition, the front seat back pocket adopts a splint-type design, which can only accommodate some small items.

The overall size of the 11.9-inch central control screen is not dominant, and the visual interface is quite satisfactory.The system is equipped with the second-generation MBUX human-computer interaction system, which supports voice wake-up, and can independently operate hardware facilities such as sunshades, sunroofs, and car windows.The measured speech system has a high recognition rate and is more accurate for fuzzy semantic recognition.The navigation system is easy to operate, with a full-color HUD head-up display system and AR real-scene navigation, which is extremely practical.

The 2022 Mercedes-Benz C-Class is equipped with a power combination of a 1.5T engine and a 48V motor. Although the engine displacement is not large, thanks to the excellent adjustment level, the parameter performance even exceeds that of the BMW 3 Series and 2.0T engines. Audi A4L.In the actual experience process, the vehicle starts relatively lightly, and due to the existence of the 48V motor, the entire acceleration process is also very smooth.

The 2022 Mercedes-Benz C-Class offers three driving modes: Comfort, Economy, and Sport. From the actual experience, the first two modes only have subtle differences, and both take comfort as the main goal.In sport mode, the throttle response is more sensitive, and the push back feeling is more obvious when accelerating.

In terms of braking performance, the 2022 Mercedes-Benz C-Class has made a compromise on comfort. The brake pedal feels soft, and there is still a certain empty position in the initial stage. However, because the pedal stroke is not long and the actual braking force release is relatively linear, it is still Can give people enough sense of security.

In terms of steering feel, the 2022 Mercedes-Benz C-Class is equipped with a variable steering ratio. The system will adjust the steering force in time according to the current speed. It is very light at low speed and becomes heavier at high speed to ensure the stability of control.

The chassis part adopts a combination of front and rear multi-link independent suspension, the suspension toughness is good, and the handling of road bumps is also relatively neat.However, the chassis is generally heavy and the sound insulation level needs to be improved.

The 2022 Mercedes-Benz C-Class tested this time is equipped with an optional intelligent driving package, including an enhanced version of driving assistance components and preventive safety systems. Adaptive cruise can realize automatic braking and autonomous starting, and the following distance supports 4-speed adjustment. The distance between the gear and the vehicle in front is kept moderate, and it is not easy to be jammed by other vehicles.The HUD function has the largest full-color display interface in its class, and adopts a long-distance projection design, which is not easy to cause dizziness when watching for a long time.

Summarize

Based on the above test results, it is concluded that the overall performance of the 2022 Beijing Benz C-Class in terms of objective data and subjective feelings has reached the expectations of the expert jury.At the level of objective data, the performance of the body craftsmanship is basically satisfactory, but there is still much room for improvement in the uniformity of paint film spraying.In addition, the opening area of ​​the sunroof and the raised height of the rear floor are also worthy of improvement.In terms of subjective experience, the 2022 Mercedes-Benz C-Class performs well in terms of lighting configuration, trunk practicability, and driving comfort, but some details still need to be optimized.On the whole, the commercial performance of the 2022 Beijing Benz C-Class is at the upper level among the tested models of the same class.
