AutoBeta(AutoBeta.net)03/11 Report--

On March 10, the well-known car blogger @ Yilu released a video of a head-on collision between Tesla Model Y and BAIC polar fox ARCFOX T. unlike previous collision standards, the media adopted a 50% offset collision standard of 66 km / h for two cars. This means that during the crash test, both Model Y and ARCFOX T collided head-on at a speed of 64 km / h and an overlap rate of 50% (driver side), and then evaluated according to the degree of deformation of the car body and dummy injury data.

It is said that the models tested in this time are the minimum version of Tesla Model Y (red car), the 2022 rear wheel drive version with an instruction price of 259900 yuan, and the same minimum version of BAIC polar fox ARCFOX T (white car), with the 2022 480s 175kW version with an instruction price of 218800 yuan. By comparison, the weight and size of Model Y and ARCFOX T are basically the same. Take the dimension as an example, the length, width and height of Model Y is 4750/1921/1624mm and the wheelbase is 2890mm, while the length, width and height of ARCFOX T is 4788/1940/1683mm and the wheelbase is 1915mm.

After the collision test, you can see that the collapse of both cars is relatively normal, but by comparison, the condition of the Model Y is more serious. After the collision, both cars have emergency flashers on and the passenger doors can be opened normally. The Model Y main driving door can be opened but with some difficulty, while the ARCFOX T can easily open the main driving door.

Compared with the degree of collapse of the two cars, the Model Y is more tragic, its main driving side longitudinal member has completely bent and completely collapsed to the innermost, while the main driving side longitudinal member of the ARCFOX T is relatively intact. Due to the loss of the longitudinal beam, the Model Y battery coolant pipe was broken, resulting in a battery coolant leakage, visual battery pack was also squeezed out of shape, but fortunately there was no thermal out of control, otherwise the consequences would be unimaginable. In addition, there are two creases in the A column of Model Y, while the performance of ARCFOX T is OK in all aspects, only antifreeze leakage occurs, and the A column is intact.

It is worth mentioning that Model Y has the operation of "losing wheel to save life" during the collision, which is very common in collision tests, especially Volvo models. Practice has proved that the vehicle "discarding" the wheel in the bias collision can effectively reduce the injury probability of people in the vehicle.

Let's take a look inside the car, whether it is Model Y or ARCFOX T, the bridge of the two cars is basically undamaged, the central control screen can also work normally, and the living space of the main driving dummy's legs has not been greatly suppressed. After the collision, the airbags of the two cars are all ejected, and the heads of the dummies are wrapped in airbags, which can effectively protect the dummies. Compared with the fuel car, the pure electric vehicle needs to have higher rigidity to protect the battery pack at the bottom and avoid thermal runaway after the collision, which is the reason why the two cars perform better after the collision with other fuel vehicles. From the comparison of dummies, both cars perform well, but the ARCFOX T is slightly better.

After the collision, the blogger also dismantled the two cars to compare the performance of the two cars more intuitively. The first is Model Y, the performance of the battery pack is relatively poor, and its battery pack has many deformations, which is the result of the heavy pressure on the longitudinal member of the main driving side, but fortunately there is no thermal runaway, while the ARCFOX T battery pack is very intact.

Looking at the body structure, Model Y is similar to the Japanese car. After the collision, the longitudinal beam completely collapses and presses directly to the firewall, which then squeezes back, causing the battery pack to deform in many places. The upper, middle and lower ends of the A column of Model Y are deformed, the lower end of the front column collapses, and the threshold beam has many deformations after extruding. On the contrary, the performance of ARCFOX T is much better, its A column does not appear any deformation, and the front column is intact, only the periphery of the threshold beam appears local deformation, but the situation is also better than that of Model Y. In the chassis part, there is a large area deformation of the front and rear floor of Model Y, while only the front floor of ARCFOX T is deformed.

According to Tesla in the previous collision mechanism test, whether it is Model 3 or Model Y, the results achieved are still relatively eye-catching. If it collides with a fuel vehicle of the same class, Model Y will most likely win. After all, as a pure electric vehicle, it has an absolute advantage in vehicle quality, but unfortunately its collision opponent is the stronger ARCFOX T, which does not have much advantage in comparison. In fact, Tesla and Toyota have certain similarities, because they are both experts in cost control and examinations. structural design and materials are all precisely treading on the standards of collision testing, no more, no less, no Jerry work, but not a lot of conscience.
