Heartwarming, reasonably priced, and excellent service. So, from the perspective of maintenance costs compared to other luxury brands in the same class, our repair costs are much more reasonable.
Yes, yes, yes, good. Let's summarize our headlights again. Four advantages. The first one? Low beam headlights with 180 degrees. The second one? The 400-meter irradiation distance. The third one? 100,000 hours of service life. Right. The fourth? And ADB adaptive headlights. Yes. So, it's about technology and user experience. These headlights are all excellent!
Let me introduce it to you. So, speaking of this, anyway, the countryside is right here! Well, to be honest, I'm also quite active online. I also receive a lot of questions from friends. This involves a point that is very closely related to appearance. That is, everyone online has asked this: it is said that only gasoline-powered vehicles typically have long cabs, but everyone takes that tram with a very short front end, right? In order to maximize space utilization in all aspects, but those Xiaomi products, Xiaomi SU7 or Xiaomi Mavic 7, why did you choose the long hood? What were you thinking at the time? What are the benefits?
Since Brother Shuang brought up the topic of this long hood, I see the current state of dismantling the car. Let's go take a look. Go directly to the car dismantling site and let me introduce the long cab to you. Good. This car has already been almost completely dismantled. The door is gone. Perhaps a cameraman will be hired. Our camera can get closer. Let me show you the current state of dismantling the trolley. This has four doors and two roofs, completely dismantled. The long cab has also been removed. You should still tell everyone. Let me talk about the long front of the car. The long hood that Shuang Ge just mentioned, let me say this first. Actually, the long hood represents proportion. What do we think about car design? Proportion is the soul. This is also what Xiaomi's car design has always adhered to. In fact, a long cab has always been a symbol of aesthetics in this century of industrial design. It includes a century-long accumulation of aesthetics. Today we're going to introduce a relatively unfamiliar term: L113. I often see this pronoun mentioned online. L113 is a distance. Where does this distance come from? We can see this side: from the root of column A, which is the tread point of our pedal, to the center of our front wheel. This distance is called L113. Generally, the longer the L113, the better the car. The longer this section, the longer its front end will be. Because we persist in this aesthetic that has been around for a century, this length of L113, plus our car front, we achieved a head-to-body ratio of 1:3. In addition, our very tight tail makes the whole side profile appear very unique and attractive. So, many people may have overlooked this: the first thing that makes this car look good is its proportions. Proportion is like a person's figure. If the figure is good, that is the major premise. What is our expectation? Nice. First of all, she has a good figure. Then it was our inheritance of the long hood design of a million-dollar luxury car. Long front, length ratio. But Mr. Lei, we just mentioned that when the front of the car is long, we have no room for compromise. Actually, this time with the engineering team, we created this aesthetic. However, we still need to ensure personal freedom in the space, family openness, sufficient and easy to use. Clear. After making the long cab, we also have several advantages. Our front trunk has a large space. And because our front is long, our safe distance has also increased. Such a collapse zone we can design to be longer in every aspect, making it safer. So the entire long hood is not just for looks; it also has many practical uses.
Yes, good. You see, we've already removed the hood. Let's take a look. Our front hood is a stick-style front hood, made entirely of aluminum. The hood is 3.11 square meters. This hood is really high and really big! Don't you feel this in the car? It's quite tall when unfolded. Everyone knows my height; I am 1.83 meters tall. You can feel how big this hood is. Such a tall hood! I just tried it and discovered I could still lift it. If it were steel, it would be very difficult to move. I told them I'm going to give it a try. Let me see if I can. I just tried it; I can move it. Of course, it still has some weight. This is an all-aluminum hood, half the weight of a steel hood.
Oh my, it can still be lifted. It really is possible. So, let me help you. Come on!
Good. This is connected. We are now, later, the advantages of using aluminum for the hood are that it reduces the overall weight of the vehicle. Our car uses a steel-aluminum hybrid body. Why use a mixture of steel and aluminum? Sometimes steel is easier to repair, but it is heavy. Use aluminum. It is relatively light. So we used a steel-aluminum hybrid in different locations. The overall percentage should exceed 91%, including high-strength steel. So this large hood is beautiful. And there are many other advantages. It also becomes safer. After we looked at our hood, the next step is to have our director colleague take a look at what we are giving to the audience. Take a look at our car and what's inside the hood after it's been removed. The whole process can be just a quick, simple look. This is our front bumper, crash beam. Then this is the one we've already demolished. The front trunk storage box is gone. Our front trunk is here. A very large place. At the time, the goal was to make the front trunk bigger. We lay down this flat one. Front-end module. This is our air barrier, air intake grille, angled. Then basically everyone can see. All the space was left for this former storage area. And what about our triangular beam? Hang all of these on it and it also provided a great space for arrangement. This structure has several key features. One: it can connect horizontally, plus a stable triangular structure enhancing strength. Two: we can manage these thermal management parts hung on this, with a very good integrated space. Everyone can carefully examine this. The camera can also take a look at what's happening in the middle. This is the small battery. We will also have colleagues come specifically to introduce what we will dismantle next, detailing one by one. But roughly, let's first look through the lens. You can take a quick look at the current state after it has been removed. These four doors have been removed. The camera can come back here and take a look. Everyone is particularly concerned about whether that chassis is available. This is a C to B structure. The battery pack and all the beams were made together. At the same time, there are four horizontal bars. This is a 2-gigapascal cable, the crossbeam of the battery pack. These two are 1,500 MPa. There's another 2 gigapascals line. Four horizontal bars in total. This is our battery pack. We internally call it the second floor. That's our BMS. These modules are all in this section. Below is the full-page battery pack. Next up is our large die-casting machine. Behind these wire harnesses is another very complex disassembly operation. The back door was also removed. Let's go back and continue talking. Because the engineers behind will continue further disassembly work on this car. Thank you all for your hard work. Come, let's continue disassembling this car. OK, our disassembly process was faster than we expected.
I heard they're going to livestream the dismantling of the car. Our engineering team is so nervous! Everyone practiced their skills diligently. I think the more they demolish, the faster it gets. Hahaha. I had them try it out a couple of days ago. It would take 4 hours to dismantle. It seems the demolition is progressing very quickly today. There are quite a few engineering students in our class today. We're all working together in parallel.
Yes, good. What about just now? Our colleagues, please also help us with this platform in front. It was replaced with a very different car model. Amethyst. Everyone can see. Can that director give us a look at this car model? Close up. Let me cut it for us. A slightly more complete shot would be great. The first thing: as you can see, this car model is a 1:8 scale model. The second thing: you might think the manufacturing cost alone is tens of thousands, but it's hundreds of thousands. Its cost is about the same as that of a car. Why is this car model so expensive? This was all done by Tian Yuan and his gang. I don't know why it's so expensive. Because in order to allow our users to have the best understanding of mass production processes, the paint on the exterior of this car is a 100% replica of our mass production process. Our amethyst car paint requires making this car film also using amethyst-based techniques. It's a complete restoration. That's really quite impressive. Because of our customized car, the product is relatively expensive. To make it easier for everyone to choose, we made a small quantity of this relatively large 1:8 scale car model, as accurate as possible in interior and exterior parts, to restore our true actual effect. Therefore, its cost is relatively high.
Good. Speaking of which, here, I'd also like to speak with you on behalf of the netizens. Since the release of our SU7 with 9 colors at once, this colorful palette has gained the favor of many consumers. What's behind this? Why did we create so many colors back then? How exactly were these colors chosen? Why these colors? Is there any story behind this? Can we chat about this?
Yes. Let me add something. Like on the street, it seems to be all black, white, and gray. Right? Black, white, and gray should account for more than 90%. Then I can say something. At that time, I was still in the product department. What we did was put all the cars in Xiaomi Science and Technology Park on the roadside and underground. I counted them all. Counted 2,000 cars. Look at their color scheme. Let alone black, white, and gray. Let's talk about white: it accounts for 70%. Our Xiaomi Technology Park, before we built cars, I remember it was in the first half of 2021. We went to see it ourselves. The first few cars I bought were all white. Because that distributor told me to buy white ones, as buying a white used car gets you a good price. Anyway, buy the white one. He listed a bunch of benefits: easy to repair. But it seems like something's not quite right after I started building cars. You introduce it to everyone. Ultimately, it all comes down to the needs of the users. We started just like before the mention by Shuang Ge to Lei Zong. In the beginning, we made cars. When the car's infotainment system is running, we will find after the survey, go to 4S stores, car modification shops, and window tinting shops. I've talked to a lot of people about color. You will discover something interesting: when you want to buy a car, everyone will recommend black, white, and gray, just like what Mr. Lei said earlier. Because it is easy to repair, no errors, very safe, and stable. But when you actually talk to this user, everyone's personality is very different. They have a particularly unique preference for color. Some people like red, some like blue, some prefer more vibrant colors. In fact, everyone has their own preferences when it comes to color. Because they believe in color, able to express their personality. We discussed it internally after we returned. A consensus was reached: since we're making colors, why can't we offer more choices? Enable users to find a choice suitable for their personality and emotions. So it all comes down to the user. Certainly, we have black and white, and they were also very beautiful. But that's not what we want to focus on promoting. So we made a lot of rich colors. Initially, we made 9 colors. And then we have continued to release even more colors. Of course, we are currently in the process of building up reserves, which may gradually exceed 100 colors. For some of the special editions, like this amethyst, we took it out and made a custom color. We still hope to meet more diverse needs.
Right, yes. Good. What color is that amethyst? It's in the custom color. My favorite color, what is its most distinctive feature?
It has the ultimate mirror effect. I consulted with Professor Gong Yi. They said it took nearly 50 hours of grinding and polishing process. This mirror effect is absolutely stunning. Have you prepared a short video? Here, because our physical product is not particularly easy to present, please have the director cut a short video for us to show you this real shot of what the mirror effect would look like. You can see that there is a chance to come to our Xiaomi car factory in Yizhuang. Or when amethyst's car is in various city tour exhibitions, if you happen to run into them, you can go and experience it. Looking at the surrounding environment through this mirror, it does indeed have a mirror-like effect. It was still very impressive.
Yes, good. So, to be honest, as far as I know, every car will have this when it leaves the factory: the process of spraying and sanding. So, let's talk about the spraying and polishing of this amethyst. Compared to ordinary car paint spraying and sanding, what are the differences? Why is this part so special?
OK. This is what our ordinary car paint looks like. They all use automated spraying robots for spraying. As for the paint finish, it has high uniformity and excellent spraying efficiency. But if it's sprayed like this, it easily has that grainy and undulating texture, which we usually call orange peel texture. If you encounter such a situation, we need to perform deep hand grinding and polishing. This process takes about 50 hours of polishing. Only by spending a lot of energy can we achieve this mirror-like ultimate effect. Very beautiful. I remember Professor Gong Yi introduced to me how they did it. It uses sand of different finenesses, 1,500 mesh and 3,000 mesh, for dry sanding and wet sanding. Use this sandpaper to polish the varnish, and the waves on this surface were gradually smoothed out. Then use lamb wool and industrial-grade sponge with a polishing compound for polishing. Only then can one achieve such clarity and a mirror-like texture. I feel that no matter what I say, it's hard for people to understand how beautiful the car's color is. If you have the chance to visit our Xiaomi car factory store or we have some cars on display recently, just look at the prototype and you'll see how amazing it is.
Yes. The craftsmanship of our amethyst, I even took some photos before. Let me introduce it in a video. This process is what makes it special. A particularly crucial term is 4C3B. Let me briefly explain what 4C3B is. 'C' represents the coating, meaning we have four coats. 'B' is for 'baking.' So 4C3B means our amethyst underwent four coating processes: intermediate color paints, then two more layers of clear varnish, then after three baking cycles. There are several advantages to this. First, it's thicker, providing ample space for polishing to achieve our mirror effect. Second, a thicker coat of clear varnish allows light to penetrate to a deeper level, creating depth of field refraction, making it more transparent and three-dimensional. Lastly, it performs excellently in corrosion resistance and stone chip resistance.
Good. So this is a custom order. Because these processes are very complicated, our production capacity is quite limited. At the beginning, we can customize a maximum of 40 units per month. Actually, that's already considered quite hard work. When we first launched this in September last year, users really liked it. We have received orders for more than 100 units. Now, amethyst deliveries have begun. In January, official delivery of this racing red car began. Regarding this customized service, in the past, only luxury cars worth millions could afford this. But Xiaomi especially hopes to offer this service, allowing owners of cars costing two to three hundred thousand yuan to also enjoy it. So we made up our minds to start piloting this customized service. Certainly, this customized service is very hard work. We sincerely welcome everyone to Xiaomi car factory's customization center to experience how our masters can help with custom-made seats, custom leather goods, and how those details were made. Friends who have visited our customized service gave very high reviews. Come and experience Beijing's industrial tourism! Currently, our customized service showcase is very limited. There are two types: a yellow one called Ultra and an amethyst one called Jade Crystal. A while ago, the exhibition toured Shanghai and Hangzhou. In mid-January, it is planned to tour Chengdu. Friends from Chengdu are also welcome to customize a unique car! Welcome everyone to see for yourself.
OK. Before that, I was chatting with Tian Yuan, and he mentioned that making so many colors is actually quite difficult behind the scenes. There are several considerations. First, with so many colors, we are all in development. Why were one or two ultimately chosen? What method did we use? Second, compared to other car manufacturers, we make a relatively large number of colors. So how is it possible to have some efficient protections? Can you tell us about this, countryside? Actually, when it comes to this issue, perhaps it's because we have a scientific process for making color decisions. Let me give you an example. I also prepared two little frogs today. When we spray paint, when to perform color verification, and then there's Lei Jun's part... These are the gems we use today. Good, please give me a close-up. Emerald green. Finally, there's our expected advertising color. It's also the color of the car being dismantled behind us. We did not release this color. However, during development, one color was called sapphire green. These two colors actually existed at the time. That was an extremely tough PvP match. Could you explain the characteristics of this color to everyone? This is a solid color paint, very bright and fresh. This emerald green is a metallic paint with metal particles, giving great depth and a 3D effect. Our designers especially love this sapphire green because many luxury supercars use this color. It's very eye-catching. But I joked with them that it looks a bit like a toy car color, a toy color. Supercars are particularly daring in using such rare colors. What we are particularly afraid of is the designer's expert mode and personal aesthetic experience leading everyone into the ditch. So we made a survey for all colleagues, not just designers. More than 200 of us voted. Everyone liked emerald green far more than this because it is more luxurious, three-dimensional, and layered. So in the end, we chose emerald green through this scientific decision-making mechanism. Speaking of which, when I have a meeting with the designer, I often joke that any design that all designers would like must have a problem. That's a joke. Sometimes designers' aesthetic sense is a bit different from the general public's. So we must conduct thorough research on the general public. We still need to go back to the user. We did a lot of research to find this out. Our team made several options. Then, after many rounds of research, I participated in Tian Yuan's judging panel. Basically, every time, it's just a bunch of colors together. Then we find the most popular ranking among everyone in this sample and a least favorite ranking. In the middle, we search again. We will definitely do a good job of creating samples and conducting thorough research and insight. Because the design of this color is very subjective. So we still need to go back to the users to see what everyone likes.
Good. Now let me look at this component. The progress of dismantling the entire vehicle has basically reached a crucial stage. Next, we will come together with everyone and talk about them one by one. The next ones we'll dismantle are part of the component design. Currently, the overall design is somewhat pastoral. That's all for now. How about inviting the countryside to take a short rest next?
Good. Lei Zong, we're together. Let's see how we take this part apart next. Let me introduce it to you.
Good. Thank you, Mr. Lei. Thank you, Brother Shuang, Tian Yuan. That camera followed us for a moment. Mr. Liu, this is one of the two exhibition samples. The one on our right is an orange chair, one of the zero-gravity seats we just dismantled. It was just taken off the car behind us. At Xiaomi, we have two zero-gravity seats in the front row, including the driver's and co-pilot's. We made a pre-made exhibition piece cut in half. Where is the seat that Xiaomi expected? It's so incredibly comfortable. Many friends gave it very high praise, calling for a long sitting period without fatigue. Next, let us ask Xiaomi's Vice President of Automotive Division and General Manager of the Architecture Department, Cui Qiang. Brother Qiang, come. Welcome. Brother Qiang goes inside. What does Brother Qiang say? He has 24 years of industry experience. Although he looks very young, he belongs to the older generation of engineers, especially experienced. Come, Mr. Li, gloves. Good. You introduce yourself to everyone.
OK. Before that, at last year's Y7 launch event, Lei Jun talked about this Y7. Come, take this KT board. This was the driver's zero-gravity seat we expected at the time, with 12 layers of structure. This time, to make it easier to display more vividly, we made a more cool anatomical chair. Let me give you a detailed introduction. Because after this chair was dissected, the structure is actually quite complex. Let me introduce from top to bottom. First, the camera pans over to the headrest. The headrest has a hollow structure inside, which is actually one sound chamber of the seat's headrest speaker, improving sound quality. Moving on to the backrest structure. The backrest is quite complex. What everyone sees are five round things, which are the air bags from our 10-point massage. Each air bag has a three-layer structure for better inflation and greater massage force. These colorful pipes are the air ducts in the inflatable bag. The mesh-like structure is the ventilation layer of the seat, allowing even diffusion of air on the back. You can also see a fan here for the ventilated seat. Inside, there's a bag-like structure for the lumbar support air bag. All our seats support ventilation, heating, and massage. You can find the heating pad below the outermost layer; the white pad is the heating pad. Why are there three different colored sponges and cushions? That's about seat comfort. The most crucial three-layer structure: the outermost is the fabric and composite sponge, using Nappa genuine leather for a soft and delicate texture. The second layer is thick comfort foam, affecting the overall comfort. The thickest part on the seat bottom is 25 millimeters, probably one of the thickest on the market. It provides uniform support and a better riding experience. Below that is a very thick white body foam layer, using high-density sponge of 75 kg per cubic meter, which provides better support and shock absorption, allowing users to drive long distances without fatigue. Most cars use 60-65 kg per cubic meter, but ours is 75.
So let me try to understand. Brother Qiang, am I right? We are related to the comfort and support of the seats. These three layers of sponge play a crucial role. The top two layers give a soft and comfortable feeling upon sitting. The bottom thick layer supports long-distance driving without fatigue or foreign object sensation.
OK. Understood. Three different layers of sponge play different roles. The seat's comfort also involves the backrest. We call this human-machine comfort. It needs to fit the human body's back contour better. The expected seat back silhouette has been optimized specifically. We discovered that Chinese users' coccyx is slightly forward compared to European and American users. The lumbar spine concave point is a bit lower. So we moved the connection point between the seat cushion and backrest forward slightly, and the lumbar support arrangement is also slightly lower. This makes the backrest fit the back's curve more perfectly, distributing stress more evenly. This is part of our comfort. Why did we make two zero-gravity seats? Most people only offer zero-gravity seats in the second row. But we have always advocated that this is the driver's car. As engineers, we hope both the driver and passenger can enjoy it. So we made the passenger seat and the driver's seat zero gravity. During charging or rest time, waiting, you can sit in your own seat and use zero gravity with one click. This was based on extensive user research; everyone actually hopes they can lie down while charging or picking up the little one. I think this is reasonable. I prefer to lie down and rest in the driver's seat. The driver's seat is still used the most. Our Xiaomi car is a driver's car. So our entire design is very comprehensive and comfortable for the driver. On the seat, we have achieved equal rights for the driver and passenger. Not just the passenger seat is comfortable; the driver's seat is also very comfortable, including the footrest. Besides driver and passenger comfort, the back row is also very distinctive, so family members will also be comfortable sitting in the back. The back seat has a very large backrest angle of 135 degrees. This angle is actually one degree more than a Maybach. Of course, that's just a little joke. It is also electrically adjustable. Now more domestic car manufacturers are starting to offer such adjustments. But electric adjustment with a 135-degree angle is still relatively rare. If you actually get in the car and experience it, it's a really great experience.
Should we go check on how the demolition is going? Let's take another look. This way. The demolition is another key part. Let's take a look at the disassembly tools first. See what tools were used. Director, please take a picture. Brother Qiang, what tools were used?
These are our torque wrenches. This is a torque wrench. It's important when decorating because it controls the torque of the fastener. Too much force or too little force won't work.
Good. Come over here. Our current one, I see my colleagues dismantling our rear axle. Lei Zong, two of our colleagues are also here. Let us introduce them. Dr. Wang Zhengsuo, with 23 years of experience after graduating with a doctorate. He worked at United Electronics for 19 and a half years. In Xiaomi Cars, he was in charge of the Advanced Power Department, covering the three-electric system: battery, electric drive, and electronic control, including our self-developed electric drive. This year, in 2025, after an organizational restructuring, he is in charge of the vehicle engineering department. Next to him is our old friend, A Chan, our Xiaomi chief test driver, the best driver. He also serves as the head of VD, responsible for dynamic performance.
Actually, I never knew either. What exactly does dynamic performance mean? He'll tell everyone about it.
Dynamic performance is how the car drives. What does it feel like to drive? It's about driving control.
Yes, yes, yes. Driving control.
He was responsible for the driving experience and handling.
Our vehicle has already been raised. Preparing to dismantle the rear axle. We invited these two engineers. Let me introduce it to you in detail.
Let me introduce myself first. First, let's look at the entire chassis. Take a look at the panoramic view.
Our entire chassis is divided into three parts. The front part belongs to the front axle section. Everyone look. And then in the middle? That is our battery pack. That's what's being demolished right behind it. That's our rear axle. The entire front axle section includes our suspension system.
Braking system and steering system. This place, actually, if we were the Max version, there's also a front motor here.
Ah. As you can see, because everyone is concerned about battery safety, so here it is. Let me introduce it to you. How do we approach this from a physical perspective? Come up to protect our battery pack. Let's look at this front end first. Protection of the entire front end, we actually have a three-story design. The first floor? It's our front bumper beam. You can see this. What if some relatively tall obstacles come over? It will definitely hit our front bumper beam first. Protect our battery pack. This first layer. What about the second floor? We also have a specially designed one here. You can see this in the camera lens. A specially designed anti-collision beam for battery packs.
It is a 1,500 MPa mega this. That is the front crossbeam of our battery pack. That's it. Right? This is the location.
Ah. Afraid of rubbing the bottom, huh?
Yes, yes, yes. Scratching the bottom. It has a design. It is lower than the battery pack. I don't know if I can capture it with a pat. It is lower than this battery pack. It ensures that the obstacle arrives. It precedes the battery pack collision. This is also our second layer of protection. What about the third layer of protection? It's the front horizontal part of our battery pack. This crossbeam. Front crossbeam. This is also a large die-cast part. It's the same die-cast part as the rear of our car body. It is also very strong. It ensures the safety of the entire structure and this seal. Therefore, these three layers of protection are to ensure our front-end collision. Let's take a look at the bottom next. This is the whole big base plate. Large bottom. As you can see, the large tablet. Could you give me a shot? That's the bottom protective plate of our battery pack. Its main function is to function as a battery pack. Protection against bottoming out and collisions. It requires a certain level of strength. Then it also needs to be scratch-resistant and impact-resistant. This whole design is a four-layer structure. We're looking from the inside out. The outermost layer is polyurea. This bulletproof coating on the material. Very strong. Then there's also scratch resistance and corrosion resistance.
This is its outermost layer. One more layer inside? It's a composite fiber material. Fiber layer. Mainly for impact protection. This acts as a buffer. Then going to the third level is a super-strong steel of 780 megapascals. It serves as a strength support. It means it needs to be both whole and strong. The innermost layer is also this composite fiber layer. It also serves two purposes. One is that insulation. Another one is the buffering effect. Therefore, through these four layers of structure, effective protection for our battery pack against impacts. This collision. When the bottom collided. This protective function. Um. Let's take a look at the side view.
Our side design is actually this three-layer structure. First, let's look at this. Let me show you the camera. This is our... uh... that side. That threshold beam. This is my threshold beam. Everyone sees it as a. It's actually quite big inside. It only covers part of it. It is a multi-chamber design. It is an aluminum extrusion process. Very, very strong.
He's quite strong! This is the first floor. On the outermost. What about the second floor? That is the side frame beam of our battery pack.
I have no idea. He is actually also. Everyone, please keep an eye on him. This is actually a multi-cavity design. There's also something inside that can't be photographed. It is also this multi-cavity design. It is also made from aluminum extrusion. Also very strong. This is two floors. Then what? Actually, the top layer of our battery pack... There are still four beams. The two are 2 gigapascals hot-formed steel. There are also two 1,500 MPa seat crossbeams. They are together, providing protection on either side. Battery safety during impact. So together, we had a full side impact. Our impact resistance can reach 820 kN. Extremely strong. So what about the entire battery pack? Well. After disassembly, I will give you a more detailed report later. Now, let Ah Chan give everyone a presentation. Let me introduce the other components.
Um. Good. That. We'll point the camera at this area. Let's take a look. Well. Now we're taking advantage of everyone's ongoing demolition... During the process of rear axle. Let's pause for a moment. Then I'll make a suspension for everyone. An explanation that wasn't completely disassembled yet. Well. As you can see here. There is a whole thing here. A very large and robust subframe.
This is black. Well. A very large subframe. So what is the function of this subframe? It is. Used to carry our entire. A suspension structure. Well. Its hinge points are all on top.
And its steering gear is inside.
So our entire front suspension. We call it a double wishbone front suspension. Well. You can see the double wishbone front suspension. Well. The lens can be raised slightly. From this perspective. Actually, there's an upper control arm involved here.
Actually, there's a lower control arm underneath. What about the lower control arm? We have two swing arms here.
At the same time? The function of this swing arm. It serves as a guide. It determines how the wheel moves. So how do we carry this car? Through this spring and shock absorber.
The spring shock absorber here is a capable... One function is to support the vehicle. And at the same time, it also eliminates vibration.
We can see the shock absorber here. There's actually another solenoid valve on top. This solenoid valve is one of our... Actively control its damping magnitude. It can be used in different modes. And under different vehicle conditions. It can control the damping magnitude to achieve. A balance between comfort and handling.
Actually, we can... What you see in the middle is actually one. A very long aluminum alloy steering gear.
That steering gear is also part of our entire... A very important part of the chassis system.
This steering gear is a multi-redundant system. Well. A device.
Here we have a double winding and... Uh, a steering gear with dual power backup. It is suitable for all working conditions. It can guarantee a high level of safety. Well. If we look this way. Actually, the entire suspension system. We also have a very important and crucial part. That is our braking system.
We have an automatic disk here. There is an automatic caliper. Well. It also contains a DPB and ESP system. What about these? We'll take it apart in a bit. Well. Everyone can see our. Looking at that part from here.
That part inside. Our rear axle already has this on top. The entire rear axle is made up of individual components. So what about this device? That's it for. In preparation for the whole. Both front and rear axles were removed. Well. So what's next? First, remove the front and rear axles. Let's move to our seating area first. Then. Ah Chan, wait a moment... Thank you, A-Can!
Good. Ah Chan, why don't you introduce yourself to everyone? You've been working for over twenty years.
Ha ha. I started working in 2004. So I've been working for 21 and a half years. Almost 22 years.
So what? What about Xiaomi? There are a bunch of them that have been around for 20 years. Automotive experts with work experience.
Um. Well. This is over the past four years.
Why are cars made so well? I believe that people are the first key to building a good car. Only by gathering global resources from all sides can we achieve this. The best talents in all fields. Only then can we truly make a good car. Good. We continue. Or should we check how the dismantling is going? I think everyone can take a look at this. All the parts are displayed here. The director can take a look. Parts that have already been removed. A great many. Although we only talked about a few.
Right. Because there are just too many parts. We simply can't explain it to everyone step by step. Everyone can take a look at this. We dismantled all sorts of things. The parts are all already laid out here. Good. Brother Qiang, can't you? Please give us a quick scan. Which ones are? Ah, this is it. I wouldn't recognize any of them if they were taken apart. Where are the rear seats?
Ah. These are the rear seats.
This is the rear seat I was just talking about, right?
Right. Seat cushion. This large angle of tilt. And the seats are very comfortable. 40/60 seat back. And it even has a sleep pillow! This headrest. This makes it easy to fall asleep while lying down. It's because this headrest is very comfortable. It provides support for the head.
This is the frame under the seat cushion of the chair.
Ah. The frame under the seat. On the second layer of the battery pack. Then I made a few boards. Go can support it together. These two B-pillars, right?
This is the C-pillar. This is the external B-pillar. This camera, this trim panel.
That's the inner panel of the door.
Come. This is our central Constance district.
Then you can see the two of us charging. This wireless charging module.
Um. And then here... This side. Main parts. These two pieces are. It is an IP station. You can see one of the covers of our speaker. Then this is our outer area. The windshield wipers outside the front windshield glass. Clear. That's our front trunk.
Ah. This is the back door. Right?
Right. This is a single-line board. It's the one-line board you just saw. One of its structures.
This is our boost module. Then during charging. It takes. If it's an increase from 400 volts to 800 volts. During this pressurization process. Some chargers have that. Just ordinary packaging.
Right. Good. Another long strip. It's the threshold. Threshold.
Ah. This is. This is the threshold beam. Right?
Right. OK. OK. Let's continue. There's still one seat left. The small details weren't mentioned to anyone. I haven't finished telling you all.
Let's continue talking about our seats. Good. Regarding the seating... A lot of effort was put in this time.
Ah. Now, please continue, Brother Qiang.
Um. Good. Besides comfort, what else does that seat offer? Another important point is that it also needs to be safe. Because the seat is part of the entire constraint. The most important foundation of the system. Just when we collided. Actually, seat belts are good too. It is closely related to the seat. Including the human body during an impact. A lot of energy will be in the seat. Therefore, the choice of materials for the seat frame is crucial. So, on this main critical force path... For example, the side panel of our backrest. The frame of the basin and us. All guide rails are made of. Such a high-strength steel with 980 MPa. Then we can put our... Bring up the frame from the back row as well. Well. Our staff will replace it. Replace this seat with that one. Let's take a look at the frame of our back row. What about the frame in the back row? This is a prop we prepared in advance. So. This is. Because if the rear seats are removed like this... Well. Relatively troublesome. Not enough time. We disassembled one of the frames beforehand to examine it. Let everyone see. First, everyone, please take a look. This is a whole. A structure of a backplate. There is something inside it. A complete circumference of such a skeleton. This frame is the same as the front seats. They all use. One piece of steel with a strength of 980 MPa. If the entire back panel is a complete steel plate. It has a significant protective effect. In this way, the luggage compartment will be subjected to this impact. Or during a collision or sudden braking.
If there are sharp objects in the luggage compartment. Then it won't puncture.
Ah. This seat. So what about this? It's the back panel of the second-row seats. A steel plate was specially placed there. 500 MPa.
Used to prevent rear-end collisions. What sharp objects are in your trunk? Objects to protect the second row of people. Member safety.
Yes. Many car manufacturers actually use a. A very thin steel plate or a plastic sheet. Then. Look at this, it's very thick. Moreover, it has high strength.
Yes. One more? This is a 950 MPa frame. Right?
980. This is a square tube beam.
So what. The overall safety of the seat is our primary concern.
How can we make our cars safe, comfortable, and easy to use? Right? Good. That's one of our seats. An introduction to a secure structure. Good. So, having said that... Well. What about our seating section? That concludes the introduction. What's next? Our expectations for Xiaomi... Actually, there are many other good product points. For everyone. Could you please provide a further introduction? Among them? What does it include? It's us! Exist. Starting with the Xiaomi Su7. Our sunscreen is very good.
Now we'll get to this location. Why. Brother Qiang, please give us another introduction. How do we handle sun protection?
Good. That one everyone knows. Whether it's a book cover or a bath period... We pay special attention to sun protection. Because of that? Well. More than half of the cars in our fleet are owned by women. So what. What about their sun protection function?
It is something we attach great importance to. Now? Although it is winter. However, low temperatures don't mean you don't need to pay attention to sun protection. Everyone must be careful about this.
