Chapter 1358 Wooden Car
In Tesla's underground research institute, high-level officials saw a new car body.The car body is not painted, and the material can be seen at a glance.

"This is the balsa wood body? How strong is it?"

Looking at the car body, a senior executive couldn't help asking.He has long known that researchers are working on balsa car bodies, but he has always been skeptical about this research.

In his impression, wood is just wood, and its strength cannot be compared with metal.Not only he has doubts, but other high-level officials also have doubts in their hearts.

"Everyone, please let me come."

A researcher leads them directly into the inner laboratory.In the internal laboratory, there are many balsa wood parts and experimental equipment.

"Everyone, these are two doors, this is a light wood door, and this is the all-aluminum door we use on our current model."

There are two car doors on a test bench, and the executives looked at the two car doors curiously.

The doors are unpainted and are in pristine condition.The higher-ups knocked on the car door curiously, feeling completely different.

The metal car door made a crisp sound when it was knocked on, and it was obvious that the interior was empty.But the balsa wood door knocked a little dull, as if it was new.

Picking up the two doors by hand and comparing them, the balsa wood door is obviously much lighter than the metal door.

The shape is almost the same, but the weight is much lighter.Under everyone's puzzled eyes, the experimenters began to conduct various experiments on the two doors.

The crash test begins when both doors are impacted with the same force.The performance of the two car doors made everyone's eyes widen.

The entry and exit doors were severely deformed by a direct impact, while the balsa doors were only slightly deformed.This result made everyone's eyes widen.

After the collision, the fire resistance test was carried out.Under the high-temperature flame, although the all-aluminum car door is not deformed, the temperature is very high.

But the balsa wood doors are surprisingly, seemingly completely unlit.The temperature inside and outside is even more extreme. The flames outside are burning fiercely, but the temperature change inside cannot be felt at all.

After a series of experimental techniques, everyone stared at the balsa wood door with wide eyes.They are all knowledgeable people, so they naturally know what this means.For automobiles, weight reduction has always been something that major manufacturers are trying to do.

The lighter the car, the lower the energy consumption.For electric vehicles, the lighter the car, the longer the battery life. This is a very simple truth.

"Why is that?"

A high-level executive couldn't help asking if he couldn't figure out why the wooden car door was stronger than metal.

"Mr. Wu, in fact, this is not ordinary wood. This kind of wood is balsa wood. After we beat this kind of wood into sawdust, we then carried out special treatment, mixed it with special glue, and then printed it directly through 3D printing."

The researchers directly took out a section of the car door, through which you can see the internal structure.The sides of the door appear to be solid.But the middle is like a honeycomb, densely packed like fillers.

"Special stamping technology is adopted on both sides. With this technology, the elasticity and rigidity of this balsa wood door are more than twice that of our existing aluminum alloy door. The honeycomb airbag structure is used in the middle, and the interior is filled with inert gas. Not only can the elasticity and toughness of the door be increased again, but it also has the effect of thermal insulation and sound insulation.”

After the introduction, they finally knew the magic of balsa wood doors.The weight of this kind of door is only one-third of that of aluminum alloy door.

At present, among global automakers, only luxury brands will use aluminum alloy doors. Ordinary models are stamped with steel plates, which are heavier.

The mass is only one-third, but the strength and toughness are more than twice that of aluminum alloy.The special adhesive is not only environmentally friendly, but also flame retardant.The inert gas inside the door can not only insulate the temperature, but also have a stronger sound insulation effect, which is much more effective than sound insulation cotton.

Wooden car doors, wooden body, in the research institute, they saw a prototype car.The entire prototype car is made of balsa wood in many places, and only a few parts of the whole car are made of metal.

The entire main frame is made of aluminum alloy and balsa wood.This craft is now only used by privately owned airships.Now under the technology, it is directly applied to the car.

This mixed process frame doubles the strength and elasticity of the body.The weight has been reduced by half, and the weight of the prototype car using this technology has been reduced by one-fifth compared with the original car.

"This is the Tesla 9 series made by us using new technology. Compared with the models currently on sale, this car has lost 300KG in weight."

When they came to the sample car, the executives saw this Tesla 9 Series.The Tesla 9 Series is a standard D-segment car and a representative of Tesla luxury.It is currently the world's highest-selling luxury D-segment car.

Careful study of this 9 series, someone soon found the difference.Whether it is the top, the trunk or the hood, it is much thicker than metal.Knock it up and make a dull sound.

"This 9-series is reinforced overall. Balsa wood is light in weight, so we increased the thickness of the entire compartment a lot, which also greatly increased safety. The front and rear of the car are especially strengthened."

Open the car, and you can see that the anti-collision steel beams at the front and rear of the car are different from the previous ones.Before that was a metal crash beam.

Now switch to balsa wood and metal.The thickness has been greatly increased, and the thickness of the entire anti-collision beam is a full 30 cm. This exaggerated anti-collision beam is not much more than a truck.

In the Safety Lab, a balsa 9 Series begins a series of crash tests.The results were brilliant.The previous 9 series was good enough, but now the new 9 series is as safe as a specially customized bulletproof vehicle.

"Has the durability test been conducted?"

asked a senior.

"The team has already started, but it will take half a year to complete the real test."

The researchers said seriously.Balsa bodywork is a technological change, so the strictest attitude must be used in all aspects.Security, durability and more.

Only after all the acceptance checks are completed can the official sale be made.But judging from the current state, this performance is very good.

正好9系也该换代了。新一代的9系将会采用轻木车身，减重300千克的9系性能将会再次提升。到时候9系豪华车霸主的地位将会无人能敌。

Now Tesla has established itself as the dominant luxury brand.It is also the most profitable brand of Tesla Group.As his own son, Tesla naturally has the best treatment. The most powerful technology is first applied to him, and he maintains the technological advantage of a generation ahead. This is Tesla's internal consensus and Tesla's confidence. where.
