Chapter 1164: No. 52

The reason why I was dumbfounded was because in the video, the two best-selling joint venture cars in China, the SUV and the Song, collided. The front of the car was completely scrapped. It looked like it was missing a section, the wheels were missing, and the engine was missing. Warehouse parts are scattered everywhere.

The two Songs looked much better. The fronts of the cars were damaged, but it was not serious. It looked like they could be repaired.

Of course, the pillars of the four vehicles were not deformed, and the airbags were all deployed.

With such a sharp contrast at a glance, these two joint venture SUVs directly collapsed in the eyes of many people.

Because it goes without saying that the two joint venture cars can be replaced with new cars. After all, the engine compartments are gone, and the cost of repairing them is not as good as buying new ones.

It's different in Song Dynasty. The main parts in the engine compartment are not flying at all, just tinkering.

Many people couldn't sit still when they saw this, and started running to the comment area to whitewash and curse people.

But the video is not over yet. No. 58 and the on-site staff began to measure the thickness and material of the vehicle's anti-collision steel beam.

"The CrV's front anti-collision beam adopts a double-layer rolled steel plate structure.

Although this structure has a certain strength, its hardness and strength are inferior to some anti-collision steel beams made of high-strength steel or aluminum alloy.

The thickness of the front anti-collision beam is about 1.6 mm.

The RAV's front anti-collision steel beam is made of ordinary steel with a thickness of 1.8. Not to mention ordinary steel plates, which have worse hardness and strength.

Let's take a look at Song's anti-collision steel beam. It is made of hot-formed steel with a thickness of 2 mm and can cover 79.57% of the front of the car.

But we can see that its cross-section is a "mesh"-shaped structure, and the two middle beams are curved. I guess it should play a buffering and energy-absorbing role in actual collisions.

But we haven’t seen what the structure of the two joint venture cars is like, because they have changed beyond recognition.

So why is it that even though the thickness of the anti-collision steel beams between Song Dynasty and these two joint venture cars are not much different, the damage to the front of the car is much lower than them?

In fact, the main reason is to use different materials.

These three cars use pressed steel plates, ordinary steel plates and hot-formed steel respectively.

The yield strength of common pressed steel plates can range from 200MPa to 500MPa, and the tensile strength ranges from 300MPa to 700MPa.

Ordinary carbon structural steel plate has a yield strength of 200MPa to 300MPa and a tensile strength of 370MPa to 500MPa.

The yield strength of hot formed steel can reach more than 1500MPa, and the tensile strength exceeds 2000MPa.

This is why the thickness is almost the same, but there is such a gap in anti-collision performance. The reason is here.

Some people here may ask why not hot-formed steel. It is very simple, of course because of cost.

The cost of ordinary steel plates is lower than that of pressed steel plates, and the costs of these two materials are much lower than that of hot-formed steel.

The production process of hot-formed steel is complex and requires special processes such as high-temperature heating and rapid cooling, resulting in higher costs.

Moreover, the welding performance of hot-formed steel is relatively poor, requiring special welding methods and processes, which increases production costs and technical difficulty.

One is that the forming of hot-formed steel requires special molds and equipment, and has higher production process requirements, which limits its application in some small car manufacturers.

I really didn't expect that the price of Song's car is tens of thousands lower than the two joint venture cars. Not only does the material far exceed them, but the thickness is also higher. It can be said that the material is very sincere. ....."

In the video, No. 58 only showed the collision results, analyzed the materials used and material costs, etc., but still did not draw any conclusions.

But anyone with a discerning eye knows that Song is far better than those two SUVs in all aspects of safety performance.

The comment area is different. It can be said that the video No. 58 has stirred up a hornet's nest.

"I feel like this video is dedicated to blackmailing joint venture cars. This blogger must have received money from the flower grower."

"I think so. How can a crash test be so testing?"

"This video is bullshit. What is a safety test? The driver in the cockpit is not injured, that's fine."

"Yes, yes, it is qualified to protect the driver and passengers on joint venture vehicles, and the front of the car is more friendly to pedestrians and non-motorized vehicles."

"This blogger definitely took money from the dealers, and actually came out to hack joint venture cars like this. Let's put it this way, even if the dealers build cars for another 20 years, they won't be able to catch up with their technology."

Of course, some people came out to fight against the injustice and support the blogger.

"I'm anxious, these people are anxious. The bloggers didn't give any definition, and they didn't say that the safety of joint venture cars is worse than that of domestically produced cars? Why do you want to put it in yourself?"

"Haha, this is not self-inflicted. Hey, if I were a car company, I would be ashamed to have fans like you. This is not to whitewash, but to do a disservice."

"Haha, I admit that many joint venture cars cannot match the craftsmanship of domestic cars, but the materials used in Song's car are absolutely full of sincerity!"

However, more people in the comment area still attack the bloggers. The final consensus is that the bloggers are paid. Otherwise, how would you have the money to do such a review? If you destroy a few cars at a time, it costs 600,000 to 700,000 yuan.

But what is unexpected is that less than two hours after the video was uploaded, "Car 52 Vision" uploaded the video again, but this is a short video, the background of this short video is the home, and it is still moving.

"I just checked the backend data, this video has exploded in views, but I read the comments, and they all said that I received money from the flower grower, otherwise how could I afford such an expensive review.

I admit that I used to work for the flower grower, but I resigned last year, because work is a kind of life experience and a seasoning for me.

Hehe, let me put it this way, first of all, I am not showing off, I just want to fight back against the black.

Because I am lucky, although I am not from a wealthy family, I have never lacked money since I was a child, so spending hundreds of thousands of dollars to do reviews is nothing to me!"

In this video, the luxury of this guy's home is indeed not something that ordinary people can compare to, and the furniture in the home is obviously expensive.

And when No. 52 accidentally took a photo of the parking lot, people kept exclaiming, because there were several sports cars parked underneath.

At the end of the video, this guy also showed off the balance of another bank card on his phone, which was 8 digits.

It can be said that this video on No. 52 directly and forcefully hit back at many people who said in the comment area that they could not afford such a review without collecting money from the family.

It made the person who said such a thing become a clown.
