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.

with its full-domain 800v high-voltage architecture, silicon carbide electric drive system and 3.7-second acceleration from 0 to 100 kilometers, the alpha s5 has successfully joined the ranks of high-performance pure electric mid-size cars, and its competitors are the popular xiaomi su7 and tesla model 3. at the same time, the alpha s5 also uses an ergonomically designed one-piece sports cloud velvet seat, and provides a wealth of intelligent network functions to fully meet the needs of family consumers, which can be described as "both civil and military". according to the data from the auto quality network, as of press time, the 2024 alpha s5 has received 7 complaints since its launch, and its reputation has been relatively stable in the short term. so, can the 2024 alpha s5 continue its current 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 alpha s5 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, a total of 10 key parts of the vehicle were selected, and 3 key points were selected for measurement in each key part to evaluate the uniformity of the gaps in each key part. from the test results, the average gap of most parts of the 2024 alpha s5 was controlled within 3.5mm, and the average gap on the left and right sides of the vehicle body was not much different, and the vehicle craftsmanship level is worthy of recognition.

in the paint film level test, it should be pointed out that since the roof of the 2024 alpha s5 is made of non-metallic materials, no valid data was measured. the test results show that the average thickness of the paint film of the 2024 alpha s5 is about 110.6μm, and the data level reaches the standard value of mid-range cars (≥90μm). judging from the test data of various key parts, except for the slightly lower paint film thickness in the trunk, the paint film thickness of other parts exceeds 100μm. the paint film thickness and spraying uniformity of the whole vehicle are satisfactory.

during 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 2024 alpha s5 was 0.01 mg/m3, which is in line with the relevant standards in the "guidelines for passenger car indoor 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 actual noise value of the 2024 alpha s5 in the stationary state was 31.4db, close to the minimum value of 30db of the test instrument. because it is driven by an electric motor, there will be no obvious noise after the vehicle starts.

in the air conditioning noise test, the test instrument is first placed about 10 cm 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 2024 alpha s5 is divided into 8 gears. when the highest gear is turned on, the noise value is 79.2db, which is higher than the same level models previously tested.

in the static in-vehicle vibration test, the vibration value of the 2024 alpha s5 steering wheel was always 0 when the vehicle was stationary and under load after starting. the vibration values ​​of the front and rear seats in both states were slightly higher than those of the steering wheel and remained unchanged, and the actual physical sensation was not very obvious.

in addition, we also tested the parking radar, lighting/vision, control system, tires, sunroof, seats, and trunk. after testing, the length of the front and rear seat cushions of the 2024 alpha s5 reached the upper-middle level of the same class, and the ride comfort was satisfactory. the evaluation car is equipped with michelin pilot sport 4 series tires, which adopt a unique sidewall suede design, can provide better wet grip, and at the same time have stable high-speed cornering performance. the tire specification is 245/45 r19. relatively speaking, the rear blind spot is larger, and the step difference between the brake pedal and the accelerator pedal is slightly smaller, and frequent alternating pedaling is prone to mixing.

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 2024 alpha s5 adopts a fastback body shape, creating a distinctive coupe posture. at the same time, the lightweight wheels, fluorescent green brake calipers and liftable spoilers further enhance the sporty attributes of the vehicle. in terms of details, the front and rear of the vehicle are designed with arrow-shaped lights, which not only enhances recognition but also forms a good response. the motor compartment adopts a full-cover design and is equipped with a large area of ​​sound insulation cotton, but only a manual support rod is provided, and the opening process is more laborious.

in the internal experience evaluation, the 2024 alpha s5 uses a 68-inch ar-hud to replace the traditional instrument panel, and the central control area has also been simplified, retaining only a 15.6-inch floating central control screen, which is responsible for most of the vehicle's information display and function operations. in terms of materials, the dashboard and door panels are made of microcloud fiber velvet premium leather, which provides high-end visual texture and delicate touch. the steering wheel is wrapped in a large area of ​​perforated leather, which can effectively increase the friction of the palm and bring excellent control experience. however, during the test, the expert jury found that there were burrs on the inside of the front and rear door panel armrests. in addition, the a, b, and c-pillar trim panels in the car will be significantly deformed after pressing, and there is still room for optimization in the details.

the front seats provide wide side wings and good wrapping. the thickness and softness of the rear seat cushions are excellent, but the middle headrest cannot be adjusted, which will have a certain impact on comfort. although it adopts a coupe design style, thanks to the large-size glass dome design, the front and rear row riding space is still remarkable. in terms of storage space, an open storage compartment is designed under the front center channel to accommodate larger items. the disadvantage is that the storage compartments on the front and rear door panels are small in volume, and the rear cup holders do not provide limiters, so water cups or bottles cannot be fixed.

the 15.6-inch central control screen is equipped with a qualcomm snapdragon 8155 chip. the car system interface is simple in design and relatively reasonable in layout, which is in line with the usage habits of most people. the touch screen is responsive and there is no obvious lag when running the program. the voice system supports mainstream functions such as dual-zone wake-up recognition, continuous voice recognition, and see-and-speak. it can operate window lifting and seat ventilation, etc. however, its ability to understand fuzzy semantics is very limited and needs further optimization.

the evaluation car is equipped with a dual-motor four-wheel drive system, and its power parameters are impressive. the initial adjustment of the accelerator pedal is not aggressive, and there will be no car-slipping. the overall power release is linear enough to create a comfortable and stable driving atmosphere. if you want to experience the powerful performance of the dual motors, just switch to the sports mode, and the power output will be more rapid. in addition, the evaluation car also provides a rampage mode, in which the power burst is stronger and the acceleration dizziness is more obvious.

the brake pedal adjustment style is different from other pure electric vehicles. the initial dead space is not obvious, and sufficient braking force can be obtained by lightly pressing it, which is in line with its positioning as a high-performance model. as the brake pedal goes deeper, the braking force is released more evenly and is easier to control.

the steering wheel feels heavy, with some sports car flavor, but the road feel is not very clear, and it is still possible to create a comfortable driving atmosphere. during the curve, the front of the car responds quickly, the rear of the car has good tracking performance, and the handling performance is remarkable.

the chassis adopts a combination of front mcpherson independent suspension and rear multi-link independent suspension, and the tuning style is soft but firm. facing minor bumps on the road, the suspension can filter them quickly, and there is almost no extra vibration inside the car. when cornering at high speed, the body roll is not large, and the suspension support is worthy of recognition.

the 2024 alpha s5 series is equipped with an l2 assisted driving system. the full-speed adaptive cruise control supports multi-gear adjustment of the following distance. the distance between the nearest gear and the vehicle in front is relatively large, so it is easier to be squeezed by other vehicles under normal following conditions on urban roads.

summarize:

based on the above test results, it can be concluded that the overall performance of the 2024 alpha s5 in terms of objective data and subjective feelings has met the expectations of the expert jury. in terms of objective data, the body craftsmanship and paint film thickness are remarkable, and the uniformity of paint film spraying is also worthy of recognition. in terms of subjective feelings, the coupe-style exterior styling and minimalist interior design are impressive. at the same time, it also has good performance in acceleration performance and driving comfort. however, the voice system cannot recognize fuzzy semantics and the cruise system has unreasonable following distance. there is still room for improvement. overall, the commercial performance of the 2024 alpha s5 is at the middle level among the tested models of the same level.
