As the first sedan car in China, Xuanyi, with a monthly sales of 50000 + yuan, is the most popular compact car in China. However, it is worth noting that the new and old models are on sale at the same time. Compared with the new Xuanyi, the old Xuanyi is more favorable. < / P > < p > from the perspective of safety, will the brand-new Xuanyi be better than the old Xuanyi, and how much performance can be improved? Should we buy the old model or the new one? To understand the original program of chedi, we can get the answer through the actual collision between two cars. (click here to watch the video) < / P > < p > among the test vehicles, the new generation of Xuanyi has adopted the sub low configuration model with head side air curtain because there are no existing cars with the lowest 4S configuration in China. The classic old Xuanyi was listed in 2012, and has only experienced a mid-term change in the United States, and there is no big change in the safety structure. < / P > < p > after the collision, the two vehicles deflected, and the front of the car collapsed to varying degrees. However, it can be clearly seen that the damage of xinxuanyi’s body is better. < / P > < p > in the subsequent door opening process, the pull-out torque of xinxuanyi has exceeded the national standard of 200N, but it can still be opened by hand. However, the situation of old Xuanyi was not so optimistic. The door was seriously deformed and could not be opened directly by hand. Finally, the door could only be removed. < / P > < p > the wheel hub of xinxuanyi is not cracked, the firewall part of passenger compartment has certain deformation, and the A-pillar of the vehicle is slightly bent, and there is a certain depression above the B-pillar. However, the whole passenger compartment has not undergone too much deformation, so the overall situation is relatively optimistic. < / P > < p > turn back to old Xuanyi. Surprisingly, 50% offset collision has already hit the 25% offset collision effect of China Insurance Research Institute. < / P > < p > the hinge part of the whole door has been greatly deformed, and the steering wheel and interior parts intrude into the passenger compartment greatly. Moreover, the lower part of A-pillar is bent, and the passenger compartment is further deformed and squeezed. < / P > < p > what is more unexpected is that when checking the damage of the body, the engine compartment of old Xuanyi suddenly smokes and emits a pungent smell, which means that the car has spontaneous combustion after the collision. < / P > < p > it is worth noting that the test vehicle is a brand-new commercial vehicle purchased in the 4S store, and the oil in the vehicle is drained out, and there is water to replace the oil. Even so, the vehicle still has spontaneous combustion. < / P > < p > in fact, the spontaneous combustion of Nissan cars after the collision is not only occurred in Xuanyi. Previously, in the C-NCAP crash test, Nissan Tianlai, after the collision, also had engine compartment fire. It seems that the fire after the collision has become Nissan’s “ancestral” skill. < / P > < p > and after the accident, drivers and passengers not only face the risk of rescue, but also face the hidden danger of vehicle fire and spontaneous combustion. At the same time, in practice, there is oil in the car, which is more likely to cause fire accidents. Therefore, under these two kinds of risks, the risk coefficient of drivers and passengers is also soaring. < p > < p > but the situation of old Xuanyi is much worse. Not only the door sill, firewall and A-pillar on the driver’s side have been greatly deformed, but the central channel in the middle of the car body has been twisted into a “twist”, which is quite exaggerated. < / P > < p > the injury value detected by the sensor on the dummy shows that the old classic elegant, chest and head injury values are very high, which means that the dummy comrade may have been “killed” at the moment of collision. < p > < p > in general, after the collision, the body deformation of new Xuanyi is about 7, while that of old Xuanyi is 21. At the same time, the classic elegant firewall intrudes into 16.4cm, and the shape variable is very large. < / P > < p > and in terms of dummy injury value, classic Xuanyi’s head and chest injuries are “poor”, which means that the dummy has been declared “dead” at the time of collision. < / P > < p > in addition, engineering testers also found the willingness of classic Xuanyi to catch fire. After the electronic fan behind the radiator was hit, the internal circuit was short circuited, and eventually the vehicle self ignited. < / P > < p > therefore, the host who participated in the crash test finally also gave the corresponding conclusion: if you can buy a new model, don’t buy the old one. Generally, but in terms of safety performance, the new model will be much better than the old model. < / P > < p > although older models tend to be cheaper, you’re just short of $12000. So your first goal is not to buy a car, but to save money quickly. < / P > < p > it is worth mentioning that in the final colored egg, the test group took down the A-pillar on the driver’s side of the old Xuanyi, and found that the A-pillar on the driver’s side was a layer of steel structure more than that on the passenger’s side. Therefore, the collision on the driver’s side may not represent that on the co driver’s side. < / P > < p > at the same time, it also makes many netizens wonder whether this is the additional “optimization” made by the old classic Xuanyi to cope with the 25% bias collision of China Insurance Research.
