In the past two years, everyone's acceptance of electric vehicles is getting higher and higher, I think that while we pay attention to the problems of battery, endurance, and acceleration, collision safety is also a reference factor for car purchase that must not be ignored, since it is legal and compliant, can be licensed, and can take the motor vehicle road, then we as a serious car, the protection should still be there.
According to the market heat, we screened out the test results of 6 models to talk to you, including Tesla Model 3, Ideal ONE, BYD Han EV, Xiaopeng G3, WEILAI EC6 and Volkswagen ID.4X.
25% bias crash test:
The 25% bias crash test is a very strict project of the China Insurance Research Institute compared to the C-NCAP, with a test speed of 64km/h, and the test at this small angle mainly focuses on the deformation of the A-pillar, the amount of cockpit intrusion and how well the dummy is protected.
1, Tesla Model 3
In this project, although the front of the Tesla Model 3 was badly damaged, the crew compartment was maintained very well, and the A-pillar position was basically invisible.
Looking at the injury of the dummy in the car, the airbags and side air curtains on the driving side of the Tesla Model 3 are all open, and the color paint traces show that the airbags support the driver's head very well and play a proper protective role.
It is worth mentioning that compared with the test of model 3 by the Insurance Institute for Highway Safety (IIHS), the domestic Tesla test results look better. Surprise or surprise. The following are the evaluation results of the China Insurance Research Institute:
2. SAIC Volkswagen ID.4X
As a product of the MEB platform, ID.4 also shows the strength that volkswagen should have, performing well in the 25% bias collision, and the A column has no visible deformation.
The driver's side airbags and head air curtains in the car also pop out at the right time to protect the driver's head in time.
The results showed that the occupant compartment of id.4 after the collision had a small amount of intrusion and did not cause injuries such as squeezing the driver's body. At the same time, we have compared the crash test of ID.4 by overseas test institutions, and the morphological similarity of the occupant compartment of the vehicle after the collision is high, which also proves that ID.4, as a global model, it has made the same strict standards for products produced and sold in each market. The following are the evaluation results of the China Insurance Research Institute:
3. BYD Han EV
The BYDHan EV also did not have a significant deformation of the A-pillar after the collision, and the crew compartment was kept intact from the outside.
At the same time, the timing of the detonation of the air bag is also very accurate, and the restraint system can also well control the excessive displacement of the dummy's body, so that the air bag can support the dummy's head more completely, and the pop-up of the side air curtain also plays a protective role.
From the inside of the cockpit, the front interior version of the HanEV has some forward movement, but from the evaluation results, it can be seen that this is less harmful to the dummy, so it is finally evaluated as G. The following are the evaluation results of the China Insurance Research Institute:
4. Xiaopeng G3
After a 25% bias collision of 64km/h, the Vehicle A-pillar has a slightly visible deformation, but the overall crew cabin structure remains intact.
From the perspective of the car, the living space of the dummy is also relatively sufficient, but with the current picture material, it is impossible to observe the leg space of the family. At the same time, the airbag pops out in time, but because the restraint system, that is, the restraint capacity of the seat belt is insufficient, as can be seen from the following figure, the body tilt of the dummy is more severe. At the same time, because the test vehicle is not equipped with a side air curtain, the dummy has a head injury, resulting in a deduction of points in the evaluation.
Evaluation results of China Insurance Research Institute:
5. NIO EC6
From multiple perspectives, ec6's performance in crash tests was excellent, with no significant deformation of the A-pillar and a crew cabin structure intact.
At the same time, the main airbag pops out in time, the dummy is well constrained, combined with the auxiliary protection of the side airbag, the overall protection of the dummy is very in place. At the same time, from this point of view, the driver's seat is not squeezed, and the dummy has plenty of leg space. Evaluation results of China Insurance Research Institute:
6. Ideal ONE
As can be seen from the figure, the A column of the ideal one is more obviously deformed, with cracks visible to the naked eye, obvious fractures and deformations at the main driving threshold, and there are slight signs of intrusion in the instrument panel, but the foot does not crash into the collapse zone. Still, ideal ONE received a G rating.
In the collision, the main airbag and the side airbag are ejected in time, but because of the constraint system, the dummy's body has a more obvious displacement, resulting in the support of the airbag is not in place, and it is likely that the dummy's head will come into contact with the hard object, resulting in a certain degree of injury. Evaluation results of China Insurance Research Institute:
Judging from the most stringent 25% bias collision link, most models can withstand the test, and individual models do lack in some aspects, and in the future, we hope to see these brands have better collision performance in new models.
Side impact
Next, we look at the results of the front-side collision of these cars at 50km/h, and generally we judge the amount of intrusion of the B-pillar by the distance between the B-pillar and the centerline of the driver's seat.
The results show that in addition to the Xiaopeng G3, other models have received G evaluations. What caused the G3 side impact to lose points was the head movement protection of the driver and occupants. In addition to the problem of insufficient restraint of the restraint system as in the 25% bias collision, the reason why the side impact results were not so good was also related to the fact that the test model was not equipped with side airbags.
Roof strength testing
In this project, the model 3 has once again achieved very good results, with a load-mass ratio of more than "5" and a Han EV, and the safety of these two cars will be higher under certain working conditions. The Xiaopeng G3 has a relatively poor performance in this link, which may be related to its front windshield extension, it seems that some strange designs still have to pay a price.
Summary: Judging from the crash test results, the passive safety performance of electric vehicles is even worse than that of fuel vehicles. Of course, this does not represent all new energy vehicles, the tests that China Insurance Research Institute has done so far are mainly for models with relatively high prices, and the lowest price is Xiaopeng G3, but from the test results, it can also be seen that its performance is still a little worse. So what about the safety of electric vehicles with lower prices and tens of thousands of yuan? At present, the highest-selling electric vehicle in the domestic market is the Wuling Hongguang MINI EV, which is also a model that can take the motor lane, can it really give the driver the last layer of safety after the accident? Also in the list of the top ten sales of new energy vehicles, there are also BYD Dolphin, Ben E-star, Chery Small Ant, Chery Ice Cream within 100,000, the visibility of these cars on the road is also very high, in the future, we hope that China Insurance Research Institute or China Automobile Research Institute can do some tests for these low-cost and high-sales models, not only to give consumers a car purchase reference, but also to urge the main engine factory to develop and manufacture better and safer cars.
