Recently, some car owners uploaded a video that according to Tesla crash test videos and other data, overseas versions of Tesla are equipped with knee airbags, so they want to confirm whether domestic Teslas also have knee airbags.
The owner removed the cover under the main passenger car of the vehicle and found that the vehicle was not equipped with knee airbags. The owner even questioned whether the Tesla he bought might not have been made at the Shanghai Gigafactory.
The knee airbags are deployed near the knee position below the center console to disperse the impact force across the passenger's legs in the event of an accident, thereby reducing leg injuries. By controlling the displacement of the legs, these airbags can also reduce secondary impacts on the abdomen and chest.
To further confirm, the owner dialed the Tesla 400 customer service number. The other party said: Knee airbags do not affect the safety of the whole vehicle, when a car accident occurs, the role of knee airbags on the safety of the whole vehicle is not high, and all domestic Teslas are not equipped with knee airbags.
Tesla said that according to the CONCLUSION OF IIHS through the crash test of knee airbags, the probability of injury with and without knee airbags is 7.4% and 7.9%, and the difference between the two is very small. In addition, in low-speed collisions, the knee airbag pops out and is likely to cause damage to the knee. In other words, the US IIHS believes that the role of knee airbags on the safety of the whole vehicle is indeed not large, and even the disadvantages outweigh the benefits.
According to the owner's description in the video, he had consulted Tesla crash test videos and other materials, showing that the overseas version of tesla was equipped with knee airbags.
In this regard, Tesla said, "According to the regulatory requirements of different markets, there may be slight differences in the functions of models sold in different countries." European sales models also do not have knee airbags, and some functions of models in China and Europe are not equipped on models in the US market. ”
Are knee airbags useful? The answer is yes, but the magnitude of the effect is controversial. In the inherent impression of consumers, the number of airbags seems to be more and more safe, when the vehicle has an accident, it can maximize the safety of the occupants in the car, but the position of the airbags is also very important, the current mainstream automotive products are basically equipped with main / passenger seat airbags, front / rear side airbags, front / rear head air curtains, etc., which can already effectively protect the occupants of the car to ensure safety. In contrast, the knee airbag is designed to protect the occupant's knee, but in fact the occupant is closer to the steering wheel position, and the knee has more space, and in the event of an accident, the knee injury is not as large as expected.
In fact, in addition to Tesla, some models such as BMW 3 Series, Audi A4L, Mercedes-Benz E-Class and so on are not equipped with knee airbags. The Japanese car is more generous, many A-class cars are equipped with knee airbags, such as Xuanyi, Corolla, Leiling, Civic and other cars are equipped.
Judging from the situation described by the above car owners, since the role of knee airbags is not large, why the overseas version of the model is equipped with knee airbags, while the domestic models do not, then it can only be said that Tesla has more confidence in the safety performance of domestic models. If you only talk about knee air bags, do you think the role of knee air bags is really big?
