AutoBeta(AutoBeta.net)04/02 Report--

Recently, the China Insurance Automobile Safety Index released the final results of the second batch of crash models. BYD Song MAX has the worst safety rating among the 11 models and is the only one in the batch with P (poor) occupant safety protection. According to the updated results of China Insurance Research, we found that the 25% bias collision and side collision of BYD MAX were both poor reviews, and the B-pillar was broken.

A car from design, research and development to production, the consideration of safety structure is very important, the level of standards set by manufacturers directly determines the safety factor of the whole vehicle, the standard is low, structural safety of course can not go up. Judging from the results, the BYD Song MAX is really miserable.

Two batches of test models a total of 23 cars, BYD Song MAX and Baojun 510 are in a relatively poor level, collision structural protection is worrying, are at the bottom of the position. Compared with the Dongfeng Honda Civic, which is also a B-pillar fault, Song MAX also fell in the small offset collision.

The Song MAX tested this time is a medium and low configuration model, which is only equipped with front airbags and front side airbags of the main driver and passenger car. The positive 25% offset collision Song MAX is rated as P (poor), which is mainly due to the lack of protection for the people in the car and the large amount of structural intrusion.

The velocity of the side impact is 50km/h. As a result, we can see that the side of Song MAX is seriously deformed and the position offset of the front and rear door is large, which is mainly due to the failure of the B-column to withstand the velocity impact of 50km. "the distance between the B-pillar and the center line of the driver's seat is 1cm, and the bottom of the B-column is completely torn," PICC commented in the report.

The vehicle B-column is the core safety structure on the side of the vehicle, because the side collapse area is very small, when the vehicle side is collided, the door and B-column need to bear very great pressure, so it is almost impossible to make any compromise.

The phenomenon of complete fracture of B-pillar has also occurred in the joint venture Civic, but the situation of Song MAX seems to be more serious and more intrusive. After the collision, the distance between the B-pillar and the driver's seat center line, Song MAX only has 1cm, while Civic is 8cm. Baojun 510, which is at the bottom of the score, also has 2.5cm.

Such a result will of course have serious consequences, such as the report that the driver's head, neck and torso will all be injured, while the rear passenger's torso is basically not effectively protected.

In the frontal 25% offset collision, Song MAX was also rated as P (poor), which was mainly reflected in the large amount of invasion in the upper part of the passenger cabin and the opening of the door in the collision. From the result diagram, the A-column has been bent and deformed.

Due to the existence of structural accidental deformation, causing harm to the people in the car, Song MAX was finally rated as P (poor) in the occupant protection project, which can be judged as unqualified.

In other aspects, Song MAX also got P (poor) for "crashworthiness and maintenance economy". Compared with Baojun 510, only roof strength and safety protection for pedestrians outside the car were left.

Interestingly, pictures of accidents between BYD and some models are usually circulated online to highlight BYD's "crashworthiness" and even spread the saying of "road tank". From the BYD official website promotion, Song MAX this car uses 3H ultra-high strength omni-directional collision absorption safety body, sounds very advanced look, as a result, it was hit in the face by China Insurance Research.

Who would have thought that a domestic brand household MPV with a price of about 100000 yuan and a top-of-the-line plug-in version close to 200000 had such a bad crash result that the firewall invaded seriously, and the B-pillar was broken, making it the second B-pillar test car in China. Some netizens even ask: "this is a low-equipped car!" No matter the low configuration and the high configuration are the same, the manufacturer will not make a difference in the main body structure of the car body, it is just a difference in power system and configuration.

In the collision test results of two batches of 23 models, we found that most foreign brands were treated differently, but the performance of Chinese cars was even worse in the same test method, and the independent brands did not improve much. We can only hope that manufacturers will make targeted improvements in the follow-up products.
