The new 4008 takes you to a true high-intensity cockpit

France: Although the $70 billion order is gone, the tensile strength of the steel of our submarine is 980Mpa

Mao Xiong: You have never seen the strength of the Soviet Union, the steel tensile strength of Russian submarines is 1100 MPa

Automotive: Hey hey, little super, automotive thermoformed steel tensile strength of 1600Mpa

Cough, classmate, wake up, look at this guy below, do you think cars can be compared to submarines?

As a thick road editor, automotive steel can really meet submarine standards in tensile strength, such as the steel strength used by volvo S90 in A\B\C column reaches 1600Mpa, the Mercedes-Benz S-Class also achieves 1500Mpa, and the new 4008 of the French system can also reach 1600Mpa.

Of course, we also know that our own pounds, a single piece of steel plate is indeed strong, the combined structural strength is naturally not comparable to the submarine. For example, the thickness of ultra-high-strength steel for vehicles is J.4mm, the submarine Z is 20mm, and the protective thickness of battleship Z is 460mm.

Why do contemporary cars love to use ultra-high-strength steel?

Back to the main topic, what is ultra-high-strength steel, and why contemporary cars must use it.

As the name suggests, ultra-high-strength steel refers to a steel with higher strength than ordinary high-strength steel. From a manufacturing perspective, ultra-high-strength steel is a thermoformed steel. The tensile strength of the general high-strength steel plate is about 400-450MPa, and it is increased to 1300-1600 MPa after heating.

The strength of thermoformed ultra-high-strength steel is 3-4 times higher than that of ordinary steel, and its hardness is second only to ceramics, but it has the toughness of steel. Therefore, the body made of ultra-high-strength steel greatly improves the collision resistance and overall safety of the body, and will play a good role in protecting the personnel in the car in the collision.

However, the cost of ultra-high-strength steel after thermoforming is much more than that of ordinary steel, and many car companies with high sales are often hyped up and used carefully. For example, Honda, the big man in the car circle Z Aicha Rice, does not have a super-high-strength steel that uses overheating in China. In addition, German non-luxury brand models, are also completely destroyed. What is even more absurd is that Toyota's first use of 1500MPa ultra-high-strength steel is on the Z new Camry, which is z for nearly 2-3 years.

The use of ultra-high-strength steel in French cars is a process of secondary protection to primary protection, and gradual improvement. The new 4008 uses 22 thermoformed ultra-high-strength steel plates with a strength greater than 1300MPa in the position of door anti-collision beams, stiffeners, neutral columns, and reinforcement plates of wind window pillars. The proportion of high-strength steel used in the whole vehicle is 74.2%.

For example, in the figure above, the door impact beam of the new 4008 has a strength of 1500MPa, which is used to withstand lateral collisions. In life, when crossing the road, an electric car runs a red light, and the double W-type anti-collision beam can play a role in resisting and intercepting. If the intensity is not enough, it is the water that rushes into the Dragon King Temple!

In the important parts of the A-pillar, B-pillar, roof guard, sidewall and rear crew compartment that make up the cockpit, the new 4008 uses 1600MPa ultra-high-strength thermoformed steel, which is the same as the Volvo S90 in steel materials.

So, the question is, how effective is the protection effect of 1600MPa thermoformed ultra-high-strength steel plate?

In terms of protection strength. For example, an 18-ton whale presses against an ant, and that pressure is almost 1600 MPa. To be more intuitive, it's the equivalent of 10 elephants dancing on your fingernails.

In the French concept of protection, ultra-high-strength steel also has the effect of preventing secondary injuries. We know that when the car collides, the cockpit will be deformed, and when the deformation is too large, it will squeeze the door, resulting in the door not being able to open, and people cannot escape from the car in time, bringing secondary injuries. The tensile strength of 1600MPa ultra-high strength steel plate is high, it is not easy to deform, it is not easy to tear, and people can be evacuated from the car in time.

With the tough B-pillar, the new 4008 also designed anti-collision pins on the doors, using the pins fixed to the horizontal anti-collision bars of the doors to transmit the collision capability to the B-pillar and the body, avoiding the door from denting inward and encroaching on the occupant space.

How deep is the water for steel welding? Luxury cars are three times the size of entry-level cars!!!

However, complete cockpit basic hardware safety also includes a welding process. It's just that welding is very labor-intensive and costly, and many car companies have played a game of information asymmetry, hiding the welding link.

Let's put it this way, the same Korean brand, the solder joints of the entry car are 1700, and the movement is 3000. The Volvo S90 Long Wheelbase Edition has 5789 solder joints. How, in terms of volume, S90 is not even 50% larger than a certain na, but the solder joint is more than 3 times more!!!

SO, why do good cars have so many solder joints?

The scientific conclusion is that the solder joints directly share the impact force of the vehicle. In the event of a high-speed collision, the more solder joints are distributed, the smaller the impact force shared by each solder joint, and the safer the body will be. It is said that the two cars in the traffic accident collide, the solder joints on the car are not enough, not strong enough, the steel plate will be desoldered, directly squeezed into the cockpit, to a "iron to eat meat".

The new 4008 and Volvo S90 also use ultra-high density welding, with a number of up to 5420 solder joints, and laser welding is used in the Z key body longitudinal girder and roof, and the welding length has reached 8.1 meters. The laser welding of the Volkswagen Passat at the same price is 3.6 meters.

Under the safety protection at any cost, the new 4008 overseas model passed the European crash test, as well as the Z-difficult 40% bias collision. The domestic model has passed the C-NCAP crash test five-star safety certification.

As far as the matter is concerned, ultra-high-strength steel, aluminum alloy anti-collision beam, these things are not rare goods at the moment. Not to mention that Japan and Germany are still steel powers, and using this thing is purely a cost consideration. But now that we have put Japanese and German cars on the altar, people are not fools, and naturally they will not use these things to show sincerity. Not only this, in the current chip shortage, people still have to take back the market discount. The Passat's offer was reduced from 30,000 to 5,000 yuan, and some decorations needed to be purchased.

In turn, the new 4008 is much more generous. The high cost of materials and processes has not affected its market sincerity. On the contrary, in the case of chip shortage, this car still has a more conscientious preferential and promotional policy.

At present, Dongfeng Peugeot has launched a "three-year first" policy. Take the new 4008 360THP Sharp Edition as an example, installments of three years, a down payment of 6666 yuan, a monthly payment of 1988 yuan, and a daily payment of as low as 66 yuan. Three years later, when it wants to replace, Peugeot will buy back at 65% of the fare.

At the same time, the car guarantee also gives you a consideration, 5 years / 150,000 kilometers of vehicle warranty + 5 years 6 times of basic maintenance (including the first guarantee). If you like to buy a compact SUV, you may wish to go to the 4S store to test drive. The driving sensation of the French car and the quality of the interior will surprise you in the actual experience.
