IVISTA China Smart Car Index released the evaluation results of the second batch of three models in 2022, among which Beijing Hyundai Elantra (2022 flagship version 1.5L) won 5 smart stars; Dongfeng Nissan Qi Jun (202 1 VC-Turbo 300 CVT 4WD Extreme Edition) and Chuanqi Shadow Leopard (202 1 270T J 16 Edition) won 4 intelligent stars.
Interpretation of China Automobile Health Index (C-AHI) Automobile Evaluation Results
In this test, China automobile health index is subdivided into four items, including VOC &；; VOI board evaluation, PM board evaluation, VAR board evaluation, EMR board evaluation, the test environment basically meets consumers' car life needs, covering high temperature exposure, electromagnetic radiation, etc. The results are very valuable for consumers to choose cars.
Evaluation results of VOC & ampVOI plate
In the tests of volatile organic compounds (VOC) and odor intensity (VOI), Audi A7L scored 9 1, Tucki P5 scored 90.5 and Beijing Hyundai Elantra scored 86.5.
The difference of scores among Audi A7L, Tucki P5 and Beijing Hyundai Elantra mainly lies in the difference of formaldehyde concentration. The formaldehyde concentration of Elantra in three stages was higher than that of the other two models, so it got a four-star rating. It is worth mentioning that the three cars have the phenomenon of deducting points from the comprehensive pollution board at room temperature and high temperature, mainly because the concentrations of formaldehyde and acetaldehyde are too high.
In the interior odor evaluation, the scores of Audi A7L, Tucki P5 and Beijing Hyundai Elantra in normal temperature stage are at the industry average level, and the scores in high temperature stage are at the industry upper-middle level, so there is still much room for improvement.
Evaluation results of powder metallurgy plate
Audi A7L, Tucki P5 and Beijing Hyundai Elantra all have five-star PM plates, Tucki P5 scored 96 points, and Audi A7L and Elantra scored 92 points.
Tucki's outstanding performance in P5 completely inherited the characteristics of his eldest brother Tucki P7. Last year, Tucki P7 got full marks in two evaluation indexes, namely "vehicle particulate matter blocking ability" and "vehicle particulate matter filtering ability", and because of the installation of "PM2.5" monitoring device, it can monitor and display the PM2.5 concentration inside and outside the vehicle in real time, prompting drivers and passengers to use the vehicle healthily, so it also got two "extra points".
Compared with Tucki P5, its purification speed in closed space is better while maintaining excellent performance. The concentration of PM2.5 in the car can be purified from 2000ug/M3 to below 35 ug/M3 within 3 minutes (according to the national air quality standard, the air quality below 35ug/M3 is "excellent"), and the filtering advantage is very obvious.
However, judging from the vehicle configuration related to particle purification in the car, SAIC Volkswagen Audi A7L is equipped with PM2.5 monitoring device and air purifier in the car; Elantra mid-high models are also equipped with in-car PM2.5 monitoring devices and in-car air purifiers. If the car selection budget is sufficient, these two healthy configurations must be selected when buying a car, especially if there are old people and children at home, which is very necessary.
VAR board evaluation results
Tucki P5, SAIC Audi A7L and Beijing Hyundai Elantra all scored five stars in the VAR evaluation, and the test scores of the three models were 93.4 points, 9 1.6 points and 92.3 points respectively.
Under the new rules, the performance of each car is different, which has opened the distance between the car companies. Especially for skin contact sensitization, some allergens in the car were exposed after step evaluation.
However, the main penalty points of the three cars are concentrated on the extractable heavy metals. The P5 content in Tucki is slightly lower than the other two cars, and the respiratory sensitization (formaldehyde) of the three cars is also deducted. Generally speaking, the risk of allergens in cars has attracted more and more attention from car companies and parts factories, and the results show that it has been well controlled.
EMR board evaluation results
In the EMR part of China automobile health index, the scores of three models are: Tucki P5 is 100, Audi A7L is 99.8, and Beijing Hyundai Elantra is 82.
Tucki P5, SAIC Audi A7L and Beijing Hyundai Elantra all got full marks in three indicators: uniform magnetic field radiation index, rapid acceleration magnetic field radiation index and rapid deceleration magnetic field radiation index, because most car companies now have their own perfect EMC (electromagnetic compatibility) management and control system, and the radiation emission control of parts and vehicles is in place.
Among them, Tucki P5 got full marks, and Audi A7L was close to full marks, because the antennas of the in-vehicle wireless communication systems in these two cars were arranged outside the car, which would bring less electromagnetic radiation than those in the car. From the result-oriented point of view, in order to reduce the high-frequency electromagnetic radiation caused by wireless communication system in the car, the antenna should be arranged as far as possible outside the car, and usually this communication will also improve the communication performance of the whole system.
Through continuous improvement and development, China Automobile Health Index will objectively evaluate the health quality of vehicle cockpit, reveal the influence of the interior environment on human health, and provide scientific reference for consumers to choose and buy cars.
At the same time, China Automobile Health Index Management Center will always adhere to the principle of "objectivity, impartiality, professionalism and authority", further deepen the continuous exchanges and in-depth cooperation with medical, communication, environmental protection and other industries, promote the research on the correlation between pollutants in cars and human health, * * * promote the healthy development of the automobile industry, * * * sketch a new picture of healthy cars in China and help realize the grand goal of "Healthy China 2030".
Summary of the Evaluation Results of the Second Batch of China Automobile Health Index in 2022
Interpretation of the evaluation results of VISTA China smart car index model
The evaluation system of IVISTA China Smart Car Index 2020 is based on version 20 18, adjusted according to the functional characteristics of smart cars, and consists of five sub-indexes: intelligent driving, intelligent parking, intelligent safety, intelligent interaction and intelligent energy efficiency. For traditional energy vehicles, only the first four items are tested; For new energy vehicles, all five items must be tested. IVISTA 2020 Edition "Intelligent Star" is comprehensively evaluated according to the evaluation results of each sub-index.
Evaluation results of intelligent driving sub-indicators
In the evaluation of intelligent driving sub-index, Elantra got excellent rating, and Qi Jun and Shadow Leopard got good rating; The main difference between the three cars lies in the "one-lane longitudinal control capability". Among them, Elantra's modern SmartSense intelligent-mental integrated safety system is eye-catching, which can identify the target car as early as possible and brake stably in the scene where the target car is stationary, the target car is slow, the target car slows down and the front car overtakes.
ProPILOT driver assistance system carried by Qi Jun and L2 driver assistance system carried by Shadow Leopard exceeded the limit in the low-speed scene of the target vehicle. When the deceleration of the target vehicle is large in the deceleration scene, the vehicle triggers the AEB function.
In the scene of one-lane lateral control, Elantra, Qi Jun and Shadow Leopard can keep driving in the middle of the lane.
In the scene where the vertical and horizontal control ability of a single lane goes straight into the corner, Elantra and Qi Jun failed to keep driving in the corner at a high speed. It should be noted that Elantra is not equipped with a road traffic sign recognition system; Qi Jun's road traffic sign recognition system can only detect speed limit signs at present, but it can't completely control the speed, just like Honda, which we are familiar with.
Shadow Leopard can keep driving in corners through high-speed deceleration, and its performance is better than that of Elantra and Qi Jun. What has to be mentioned here is that Shadow Leopard is the main sport, equipped with ZF DP-EPS high-performance steering system and Michelin Pilot SPORT tires, which not only has more accurate steering, stronger tire grip, but also is light and flexible when turning at low speed and has better car condition.
