Is there a difference between the test results of Mazda 3 Axela in CIRI and IIHS?

CIRI Auto Technology Institute (CIRI) and IIHS are both related to the interests of the insurance industry, and their testing standards and content are similar, and they are well-known and recognized in the industry. And Mazda 3 Axela, the results of the two test institutions are also consistent excellent.

Car safety has always been a topic that will never go out of fashion. Since the birth of the car, various car companies have been intensively working on car safety technology, from the use of high-strength steel to the application of structural mechanics to the popularization of active safety configurations. There is only one point behind this series of practices, which is to make vehicles Have the ability to better protect the safety of drivers and passengers.

So how can car companies' efforts on car safety be better and faster quantified? In addition to referring to the national standards and the company's own standards, the crash test results of third-party crash test institutions are the most worthy of attention. After all, the best way to understand the safety performance of a model is to directly come to the field for crash test. From the current point of view, the IIHS of the United States and CIRI of China are among the many automobile crash testing institutions that are more respected by China and the United States, because its organizers are insurance agencies, and the results of the crash test will directly match the last of this model. The premium is directly linked. So, what are the similarities and differences between the test content and test methods of the two? Is there any model that can achieve good results in the two major testing institutions?

Standards are roughly the same, but differences in the details

IIHS mainly evaluates the safety of vehicles through six tests: frontal offset collision, side collision, head restraint and seat safety test, roof static pressure test, active safety test and headlight test. Among them, the frontal collision includes the frontal 25% offset collision of the main and co-pilot and the front 40% offset collision.

According to the different scores of each indicator, IIHS divides the results into four levels: G, A, M, and P. IIHS will select TOP SAFETY PICK and TOP SAFETY PICK+ models for awards based on the test results of different models every year, which has affected the choice of American consumers for models to a certain extent.

CIRI is similar to IIHS. It is an automobile crash testing organization jointly established with China Automotive Engineering Research Institute and CIRI Automotive Technology Research Institute under the guidance of China Insurance Industry Association. It not only refers to the testing content and testing methods of the US IIHS The standard and performance evaluation are the same as the IIHS of the United States, divided into four grades: G, A, M, and P.

In the testing process, CIRI also mainly evaluates the safety of the vehicle through six tests: frontal offset collision, side collision, head restraint and seat safety test, roof static pressure test, active safety test, crashworthiness and maintenance economical test.

It can be found that the most intuitive difference is that IIHS has a unique headlight test, while CIRI has a unique crashworthiness and maintenance economy test. This is because almost half of fatal car accidents in the United States occur in dark driving conditions. Therefore, the lighting of the headlights, to a certain extent, determines the safety of driving at night. Therefore, IIHS regards this performance as the test standard. CIRI's unique crashworthiness and maintenance economy test is related to insurance interests. The use of 15km/h low-speed rear-end collision has little to do with car safety, but it is the most common traffic accident.

On several other similar tests, the CIRI and IIHS tests are basically the same. For example, side collisions are all using MDB with a mass of 1500kg to hit the driver's side of the test vehicle at a speed of 50 km/h, but the IIHS is slightly higher than the CIRI in height. The driver's position of the test vehicle and the second row of the left seat A dummy is placed on each seat to measure the damage of the driver and the occupant on the left side of the second row during the collision.

The static pressure test of the roof uses the ratio of the peak load measured within the displacement range of the pressure plate to the weight of the vehicle to evaluate the compressive strength of the roof. The difference is that the rigid plate of the CIRI loading device applies a load to the test vehicle at a speed of about 5 mm per second, while the IIHS applies a load to the test vehicle at a speed of about 1/8 inch per second. For head restraint and seat safety tests, CIRI and IIHS both use a speed of 16km per hour.

The biggest difference occurs in the frontal offset crash test. The IIHS frontal offset collision includes the frontal 25% offset collision of the main driver and the front co-driver and 40% frontal offset collision. CIRI currently only includes the frontal 25% offset collision of the main driver. However, according to the China Insurance Automobile Safety Index on February 5 this year. The "China Insurance Automobile Safety Index Regulations (2020 Edition)" was officially released on the official website, and the first officer's 25% offset collision has been officially included in the evaluation and will be officially implemented on March 31, 2021.

It is worth mentioning that the frontal 25% offset collision is currently the most stringent item in the passive safety crash test of automobiles. At present, only IIHS and CIRI with insurance company background are doing all the crash test institutions in the world. In addition, the cars selected by the two organizations for testing are generally hot-selling or high-attention models in the market, and the test models are basically low-to-medium models in the car series. This is an important reason why the two crash test institutions can be trusted by more and more consumers.

Few products that can perform well in both institutions

Recently, the 2021 IIHS crash test safest list was released. IIHS awarded 49 models with the "TOP SAFETY PICK+" highest safety + rating, more than twice the number in 2020, reaching 23 models. As of now, CIRI has tested a total of 64 models, and none of them has achieved full excellence. Especially in the crashworthiness and maintenance economy tests, only two models received a G rating.

In addition to crashworthiness and maintenance economy tests, only 21 models of C-IASI currently have a full G rating. Among the 43 models that failed to get a full G rating, 37 models failed to get a G in the frontal 25% offset crash test.

In addition to crashworthiness and maintenance economy tests, the author found that Mazda 3 Axela has not only received an excellent rating from CIRI, but also received the highest safety + rating of "TOP SAFETY PICK+" by IIHS for two consecutive years.

It can also be seen from CIRI’s most stringent frontal 25% driving test scene video that the A-pillar of the Mazda 3 Axela can be said to be motionless when the impact occurs. In addition, the lowest equipped model is still equipped with 6 airbags including side curtain airbags. It is indeed the strength to get such a good rating. This directly proves that, as a global model, Mazda 3 Axela does not treat it differently in terms of quality standards due to different markets.

In fact, the Mazda 3 Axela launched in 2019 applies a lot of Mazda's latest design and technology. For example, in terms of safety, Mazda 3 Axela has increased the use of high-strength 1800MPa steel, and the proportion of ultra-high-strength steel of 980MPa or higher has greatly increased, from 3% of the previous model to 30%. At the same time, a closed-loop body design is adopted to speed up the force transmission path when the vehicle collides, and the vibration caused by excessive stiffness is absorbed by adding a damping block.

Summary: A rigorous, fair, and neutral crash test is designed to allow consumers to more clearly see how a car's safety performance is under uniform standard test conditions. This will further promote automakers to continuously strengthen the body structure and safety of their models. Only in this way can we achieve a win-win situation for car companies and consumers.

Mazda 3 Axela has achieved very good results in the rigorous crash tests of IIHS and CIRI, which proves that Mazda models have global safety standards, and the quality will not differ depending on the country or region. Of course, for consumers, safe driving comes first.
