Lei Jun: Xiaomi answers 100 questions from netizens (full version)

There are many topics my friends are concerned about when it comes to Xiaomi cars. My colleagues at Xiaomi Auto selected the 100 most typical questions. I helped you sort out the full version of the content answered over three days.

We initially planned 100 questions, and actually answered 101 questions. If you are interested, you are also welcome to check back at the full content of our technical conference.

There is a lot of feedback from rice fans. Recently, there have been so many rumors about Xiaomi cars. Is Xiaomi's legal affairs really working? When will relevant developments be announced?

A: We only held an automotive technology conference this time, and the popularity surpassed our expectations. On the one hand, the huge popularity represents users' expectations for Xiaomi cars, and we are really happy. On the one hand, a large amount of false information, rumors, and malicious discrediting has also flooded in. We will promptly clarify them, and we will also resolutely pursue the legal responsibility of those who create rumors and discredit them.

What is the approximate price of the Xiaomi SU7? When will it be announced?

A: We do not have a final pricing yet. I also introduced it at the Xiaomi Auto Technology Conference. It's certainly a bit expensive, but it's “expensive for a reason.”

It won't be 99,000, it won't be 149,000, it won't be 199,000. The final pricing will be announced at the official launch of the Xiaomi SU7.

There is a lot of news about the price of Xiaomi cars online now. Is this true?

A: The internet reports that the prices of Xiaomi cars are all fake, and we haven't decided on the final price yet. The final sales price will be announced when the Xiaomi car is officially released.

Is the main content of the Xiaomi SU7 basically finished?

A: On December 28, 2023, the technical conference for Xiaomi cars was held. This time, we have only introduced the 5 core technologies of smart electric vehicles, and only an overview of the products. We also have a large number of technologies and product details that have not been developed. I'll give you a detailed introduction at the official launch of the Xiaomi SU7.

Is the pressure higher the better for large die castings? Why is the Xiaomi Big Diecast 9100t?

A: What we often talk about here is the clamping force of large die casting. The clamping force is determined by the design of the die casting part. The Xiaomi integrated die-cast rear floor is larger and the structure is more complicated than the Tesla Model Y, so in the end, 9100t rated clamping force was selected. In actual use, the maximum clamping force of small to medium rice super large die-casting is 9500t, and the stable value can reach 9300t.

Clamping force is not the only indicator of large die casting technology. The performance of heat-free alloy raw materials, die-casting island cluster design, defect detection, etc. are all core indicators for measuring large die-casting technology.Currently, Xiaomi is the only car company in the world and the only domestic car company that also has self-developed heat-treatment-free alloy materials and a self-developed large die-casting island cluster.

Some people on the Internet say that Xiaomi's large die-casting was directly renamed from Haitian's existing 8800t die-casting machine. Is this true?

A: Of course not. The Xiaomi Super Large Diecast 9100t (ton) is not a model, but an actual rated clamping force. In fact, the clamping force of the Xiaomi Super Large Diecast Cluster can be as high as 9500t for normal operation. It is worth mentioning that the Xiaomi Super Large 9100t die-casting machine was jointly developed by Xiaomi and Haitian. The Xiaomi R&D team carried out 11 patent design innovations and upgrades based on the industry's existing die-casting machine technology. Most of them are invention patents, such as AI actively optimizes injection parameter setting systems.

But the die-casting machine is only one link,Xiaomi has developed the entire die-casting cluster system, including 60 devices and 433 process parameters.More details can be found at this link:

If it actually hits a large die casting, how high is Xiaomi's maintenance cost?

A: The tail of the Xiaomi SU7 uses a three-stage design, and the buffer zone is designed on the basis of an integrated large die-cast rear floor. Conventional collisions only require the replacement of the buffer collapse area, and the maintenance cost is the same as traditional design. In the event of a very high speed collision, the integrated large die-cast rear floor can provide better safety protection.

Overall, the integrated large die-cast rear floor design of the Xiaomi SU7 is:Small collisions are easy to repair and cost less, and large collisions are stronger to protect your safety. It's the best solution right now.

Does Xiaomi have a high yield rate of large die casting? Will using large die casting as soon as it comes up cause quality problems?

A: Large die-casting technology is a typical long-term technology, and it is also an entrance ticket for leading car companies in the future. From the beginning, Xiaomi decided to do full-stack self-research and invest in two sets of die-casting island clusters at once. In order to ensure that it was foolproof, we also added a traditional stamping plan at the time, and three sets of solutions were executed at the same time. Finally, Xiaomi's super large die-casting project was successfully implemented.

At the same time, we have developed our own technologies related to large die-casting islands, including temperature control systems, aluminum liquid transfer systems, injection systems, pouring systems, etc., and we ensure the yield rate of the Xiaomi SU7 integrated large die-cast floor through our self-developed AI defect detection system.

What is the actual performance of the Xiaomi Titan alloy? Is the self-developed alloy just to save costs?

A: The Xiaomi Titan alloy is excellent in die-casting performance, mechanical properties, durability, recyclability, and economy. The Xiaomi Titan alloy also contains 30% recycled aluminum, which is very environmentally friendly. Xiaomi has become the only domestic and the only automobile manufacturer in the world that can mass-produce large die-cast materials.

As to why we developed our own alloy materials at the time, I also mentioned it at the press conference because large die casting required alloy raw materials. At the time, the supplier's formulations could not meet our requirements; we were only able to develop our own materials. The cost of self-developed materials was definitely much higher than directly using mature solutions.

! 10

Was the Xiaomi Titan alloy really self-developed?

A: Yes. Some netizens may have been misled by misinformation before. What everyone saw was a chat transcript of a professor surnamed Yang from a certain university. In fact, Professor Yang quickly clarified it. I commend Professor Yang for his realistic spirit and regret the misunderstandings caused by this. Hope everyone can help retweet and clarify.

What are the differences in the specific formula of the Xiaomi Titan alloy?

A: The relevant patents are publicly available, and the proportions of the eleven elements used in the alloy have also been disclosed.

Patent number: ZL 2023 1 0604165.9

How many of the Xiaomi supermotors are self-developed?

A: We have officially released a total of three motors, and also revealed a pre-developed motor that has already been experimentally realized. Among them, the Xiaomi supermotor V6 and V6s were jointly developed with UMC and Huichuan respectively, with a speed of 21,000 revolutions. At the same time, Xiaomi developed its own Xiaomi supermotor V8s, with a speed of 27,200 rpm. This information was also publicly disclosed by Huichuan on the A-share investor interactive platform. For an introduction to the Xiaomi supermotor, please click on the link:

Is the Xiaomi Motor V6 just an old UMC product? Why are all the model names the same?

A: The Xiaomi Motor V6 is a new motor jointly developed by Xiaomi and UMC. Through the joint efforts of both parties, the motor rotor stress topology was improved, the motor speed and power density were greatly increased, and related patents were obtained.

Internet reports that the so-called “Xiaomi Motor V6 is the 2020 UMC TZ220XS000 old model motor” is pure rumor.TZ220XS000 is only named after national standards: TZ represents a permanent magnet synchronous motor; 220 represents the outer diameter of the motor; X represents the rotation position sensor; S represents water cooling and heat dissipation; 000 is UMC's brand code.The same internal name does not mean that it is the same motor; this can be learned from publicly available information in the industry.

Will V8s motors be mass-produced?

A: The V8s has been mass-produced and will be launched in 2025. At present, automobile evaluation media have measured construction vehicles equipped with V8s motors, and the actual speed of the V8s can reach 30,000 revolutions or more. However, the relevant test is a limit value test. We still calibrated the maximum speed of the V8s to 27200 revolutions.

How did the Xiaomi supermotor achieve a high speed of 35,000 revolutions? When Xiaomi first made a motor, it was better than Tesla and the like?

A: Behind the high speed of 35,000 rpm, there are innovative efforts in many aspects such as structural design and material technology. Among them, the most important one is,Xiaomi used “laser in-situ curing carbon fiber winding technology” to innovate the design of high-speed motor rotor sleeves and obtained relevant authorized rotor patents.

Compared to the carbon fiber wet wrapping method where “after carbon fiber is wound, you need to brush resin to cure”; Xiaomi's laser in-situ curing wrapping process does not use carbon fiber raw wire and resin glue, but carbon fiber pre-impregnation tape. The process is simple. The process is simple. The process is simple, all are completed at one station, and the tension is directly maintained during the wrapping process.

Are CTB inverted batteries really the first in the industry?

A: There have been cases in the industry where batteries are inverted; pressure relief valves have also been inverted. However, the CTB cells, where the first two were inverted at the same time, were completely inverted, which had never been the case before.This technical solution pioneered by Xiaomi is to guarantee the ultimate battery safety while also ensuring the ultimate use of space.

CTB is a cell to body, a design capability of automobile manufacturers. It is not only the battery manufacturer's technology. Essentially, the battery pack is integrated with the car body, and the top cover of the battery pack is directly the floor of the passenger compartment. Xiaomi has 36 core patents. Structural designs such as the CTB integrated cover, side panel design, bottom guard, and composite fiber dragon backbone are all designed by Xiaomi. Low-conductivity coolant, battery management software, and car cloud integrated safety warning systems, and high-pressure architectures are also all designed by Xiaomi.

What are the specific benefits of the Xiaomi CTB inverted technology solution?

A: The Xiaomi CTB battery pack uses an inverted battery design. Compared with traditional upright batteries, the pressure relief valve is facing downwards. In line with the only non-porous high-strength steel cover design in China and the world's most stringent thermal loss control safety standards, the passenger compartment is also completely isolated from the battery compartment.

Even when the heat at 55 degrees Celsius gets out of control and there is no open flame or heat spreading, the pressure relief valve is facing down and the top cover is non-porous, forming a ceiling that can protect battery safety.

How high is the aerogel content of Xiaomi batteries? Is it standard?

A: The Xiaomi SU7 uses the industry's top 17 layers of high-voltage insulation protection and customizes the industry's strongest active cooling technology: the double-sided cooling area reached 7.8 m², the highest in its class. This amazing figure is 4 times the industry average. At the same time, 165 sheets of the industry's most advanced aerogel insulation material are placed on both sides of the battery, which can withstand temperatures up to 1000°C.

During the test, our engineers were extremely confident in innovative materials and processes. They dared to hold their hands close to the aerogel material and directly burn it with a 1000°C spray gun on the other side, and it was still safe and sound.

Some netizens wonder if the thermal management of the Xiaomi SU7 adapts to low temperatures and can only reach -20℃. Is this true?

A: Regarding the scope of work of heat pumps, there are currently no strict regulations in the industry. Some companies claim that it can be as low as -30℃. In fact, it is not a pure “air source heat pump,” but rather a heater or water source heat pump is working.

As revealed at the Xiaomi Auto Technology Conference, -20℃ relies on pure air source heat pumps, and can still obtain heat from the air.

If you follow the same caliber as the relevant company mentioned above, plus heaters, etc., the overall thermal management capabilities of Xiaomi cars can adapt to temperatures as low as -30℃ or even lower.Therefore, Xiaomi can challenge the “king of winter trains,” and it can be said that “trains have never been afraid of cold winter.”

Was Xiaomi's Modena platform completely self-developed?

A: The Xiaomi Modena platform is a fully self-developed car platform by Xiaomi. Earlier rumors claimed that Xiaomi cars use architectures from other car manufacturers, which is completely untrue.

The Xiaomi Modena platform was established at the beginning of development100 “first”, “only” and “best” design goalsWe also shared some of the results with you at the Xiaomi Auto Technical Conference. At the same time, we will report more results in detail when Xiaomi Auto is officially released.

Said it was the design goal of “first, only, and most of the 100 items”. Has it actually been achieved?

A: We talked about the “design goals” at the press conference. In fact, the vast majority have been achieved. Due to time limitations, we've only talked about some of the leading technologies and features of Xiaomi cars. More details will be introduced to everyone in the future until the SU7 is officially released.

What can Xiaomi's intelligent driving rely on to achieve the goal of “entering the first camp in the industry in 2024”?

A: Xiaomi's intelligent driving uses a full-link self-developed solution. Moreover, Xiaomi has a very high starting point. On the basis of the latest generation of the underlying algorithm - BEV+Transformer+ Occupancy Network, it fully incorporates big model technology into it.For the first time in the world, an end-to-end perception decision model has been applied to mass-produced vehicles.

The Xiaomi SU7 Elk test score of 82km/h was tested according to what standards?

A: The Xiaomi SU7 Elk test was carried out in full accordance with the international standard ISO 3888-2, and the Elk test score was 82km/h. If you are careful, you will find that the road width in the middle of the test is still slightly narrower than the national standard, making it even more difficult for yourself. The Elk test is a comprehensive test reflecting a range of abilities such as handling and body stability. After the official launch of the Xiaomi SU7, the media are also welcome to compare actual tests.

Will Xiaomi release a “Gangster Among the Gods” version in order to lower the starting price?

A: Please rest assured that Xiaomi cars have fully consistent product design guidelines, and “experience first” always comes first. The Xiaomi SU7 is the standard version.

Is a five-star safety collision standard? Is there a difference in collision safety performance between the standard version and the MAX version?

Answer:No matter which version of the car, the safety crash test results are top notchWe chose the strictest standards to design our products. The Xiaomi SU7 series all met C-NCAP 2024 five-star safety standards, E-NCAP 2023 five-star safety standards, and C-IASI 2023 3G+ excellent safety standards.

Are Xiaomi cars only available in three colors? Will the production version be white and black? Will there be hunk fans?

A: This time, we announced the three color schemes of the Xiaomi SU7, namely Bay Blue, Olive Green, and Elegant Grey. The three colors are all very beautiful on the actual car. Our design team has put a lot of effort into color development and car paint process.

We also see many users asking if there is a classic black and white color scheme. We do have more colors to choose from, and we'll give you a full overview when it's officially released.

Why hasn't Xiaomi considered redesigning a new logo?

A: We are very satisfied with the Xiaomi car logo design. It is in line with the Xiaomi brand logo. It is an important brand asset for us. Aesthetics is a subjective matter, and we will also listen to everyone's different voices with an open mind.

Why was the first car called the Xiaomi SU7?

A: “SU” is an abbreviation for Speed Ultra, and “7” is a series positioning determined according to the common domestic perception of model positioning. The size of the model is about the same as the BMW 5 Series. High performance is in Xiaomi's DNA. Tesla said it won't build slow cars, and we did the same. As for how to pronounce it, we also had serious discussions internally. In the end, everyone thought it was still called “Su-7,” just like calling a friend's name, which is quite kind.

! 29

Will the Xiaomi SU7 go on sale globally?

A: At present, we will focus on the official launch and launch in China. But our ultimate goal is:There are Xiaomi cars racing on every street in the world.

Will Redmi cars be launched in the future?

A: Without this plan, we are still focusing on Xiaomi cars, or even more specifically, our first car —— The entire production and sales chain of the Xiaomi SU7 has been completed.

When can I see the actual Xiaomi car at the nearby Xiaomi house?

A: After the official launch of the Xiaomi SU7, we will simultaneously provide you with a real car experience at the Xiaomi Home in key cities across the country. We are actively preparing for this work, and we ask everyone to wait patiently for a while longer.

Mr. Lei said earlier that Xiaomi has no rivals within 500,000. Is that a joke or serious?

A: This is a comment I was replying to a netizen in the comments section at the time. Although it was a joke, it was also serious. At the press conference, we used the Porsche Taycan Turbo and Tesla Model S to make many comparisons, including design, performance, battery life, and vehicle safety. The actual comparison results are very clear to everyone. The pricing of these two cars is also clear to everyone. We are more pragmatic and won't set up those outrageous flags, so we are still very confident that the Xiaomi SU7 currently has no rivals within 500,000.

Did Mr. Lei focus on building cars after him? Do you still have the energy to make a good phone?

A: Mobile phones are still Xiaomi's core business and the core foundation of our “Full Ecosystem for People and Cars” strategy. I still pay great attention to technology research and development in the mobile phone business. At this stage, my time and energy allocation is roughly that at least 1/4 of my time is still spent on the mobile phone R&D business, 1/4 of my time is focused on group operation and management, and 1/2 of my time is spent on the automobile business.

Recently, quite a few netizens have reported that some manufacturers are frequently maliciously stealing the popularity of Xiaomi cars and even attacking Xiaomi cars. How are you responding?

A: Shifu Zhi Jin Cao and Lu Yao know horsepower. Time will tell everything. We believe that proper discussion of products, technology and experience is healthy competition, and only healthy competition can effectively promote the healthy development of the industry. We believe that most disputes between peers can be resolved by communicating with the utmost goodwill. Of course, when necessary, we will also use legal weapons to protect our rights and interests.

Why is the Xiaomi SU7 designed to start with a physical button with one click?

A: We have thought about this design over and over again: First, the Xiaomi SU7 is based on the concept of retaining mechanical buttons, in line with human intuition. It retains mechanical buttons such as one-button start, air volume, electric rear wing, suspension height, etc., and can expand physical buttons on the large central control screen.

At the same time,Xiaomi SU7 is a mobile smart spaceOne-click startup divides the parking and driving zones into two spaces. When parking, the ecological screen will display the parking model page. It is a connection between virtual and reality. The driving card page is simple and easy to operate when driving. Also, it has a special sense of driving ceremony. After starting with one click, it is also equipped with a series of linkages such as a rotating instrument, seat adjustment of the driving position, and steering wheel return. The driving ceremony is full, and every drive is worth remembering.

What is the red button on the bottom right of the Xiaomi SU7 steering wheel for?

A: The red button is the Boost mode activation button on the Xiaomi SU7. When speeding up and overtaking, press the “red boost button” to provide 20 seconds of excess torque output. In line with the speed flow of the instrument screen and the large central control screen, your blood will burn with every acceleration, so you can enjoy the sports car experience to the fullest!

The Xiaomi SU7 also supports the “catapult start” mode. When both pedals are pressed at the same time when starting, the power system is instantly fully activated. Within 170ms, it provides the ultimate acceleration of 0.95g.

Does the Xiaomi SU7 use a screen shift or a pocket shift lever?

A: The Xiaomi SU7 uses a Huai-style electronic lever to shift gears.

Why was Xiaomi's first car a sedan, not an SUV?

A: Automobiles are the “king of industry”, and sedans are typical representatives of the “zeitgeist” of every era, and are the first choice for the “elite of the times” in every era.

From the beginning of the product definition,The Xiaomi SU7 requires both high performance, ecological technology, and intelligent space experience. Only an outstanding car like this can have the opportunity to perform all three to the ultimate.

Therefore, our first car was positioned as a C-class high-performance eco-technology sedan, the first choice for the elites of the times, and a top benchmark in technology and culture.

There's another very important reason. Everyone familiar with automobile development knows that “it's easy to drive tall cars, difficult to drive low.” Building a car is the hardest path, but Xiaomi is determined to continue to advance steadily on the century-old automobile circuit. We have firmly chosen not to take shortcuts and do difficult and long-term valuable things.

The Xiaomi SU7 uses a slip-back coupe design. How is the interior space in the car?

A: The Xiaomi SU7 has both the attitude of a sports car and the large space of a C-Class. The height of the dummy model used in our design space is 188 cm. The vertical space in the front row of the Xiaomi SU7 reached 1012 mm. The front passenger has plenty of head space, there is still room for the rear head, and 105 mm of rear knee space, which exceeds that of the Model S and BMW 5 Series in the same class.

Why is the price of Xiaomi cars not being announced? Some people say they are hesitating when they see pricing from other manufacturers. Is that right?

A: Of course not. The Xiaomi Auto Technology Conference was held on December 28 last year. We mainly talked about technology, and incidentally, we talked about some Xiaomi SU7 product information. There is also quite a bit more information about the Xiaomi SU7. We will wait until the official product launch to give you a detailed introduction.

The automobile industry is really booming now, but Xiaomi is growing from small to large, and has never been afraid.Still saying that, we are very confident that the Xiaomi SU7 has no rival within 500,000.

When will the 35000 rpm motor pre-developed by Xiaomi be mass-produced? What models will it be placed on?

A: Motor technology is the core technology for new energy vehicles, and it is also a long-term track in the field of new energy.In the field of motor technology, Xiaomi uses a strategy of assembly generation, mass production generation, and pre-research generation.

The 35000 rpm rotor we showed at the press conference is the core component of the next generation of high-performance motors currently being developed by Xiaomi. Its groundbreaking use of carbon fiber laser-wound rotor technology will further break through the motor's power density limit. At present, the research and development of the project is progressing smoothly. We will report the relevant progress in detail with you in the future.

Was the car driving in the previous video of the auto media person Kang Yue a modified car or a mass-produced car? Is it much different from the commercial version?

A: The Kangyue test was a test vehicle equipped with Xiaomi's fully self-developed V8s motor. This car easily broke through 300+ km/h in the standard high-loop test and reached the peak of performance of a new energy vehicle.

Other than the motor, this test vehicle is not much different from the mass-produced car. It is also equipped with the Modena platform architecture developed by Xiaomi. The speed of 300+ km/h also confirms the huge platform performance potential of the Xiaomi SU7.

Is the wind resistance coefficient an IQ tax? Is racing only useful?

A: The wind resistance coefficient is not an IQ tax; wind resistance is science. When the vehicle speed reaches a certain level, a large amount of energy consumption will be consumed to combat wind resistance, and reducing wind resistance can significantly reduce energy consumption. For example, for new energy vehicles, for every 10 count reduction in the wind resistance coefficient, the driving range can be increased by 7-8 km, and wind noise can also be reduced while reducing wind resistance, which can provide better riding comfort.

At the press conference, we introduced an air resistance formula. The wind resistance coefficient is something we can work hard to reduce.The Xiaomi SU7 has a wind resistance coefficient of 0.195 at 160 km/h, which is the strongest performance among mass-produced cars in the world.It will bring extremely low energy consumption and excellent battery life.

How useful is an electric tail in practice?

A: The Xiaomi SU7 uses a large number of aerodynamic components found only in top performance models. Among them, the electric rear wing is the core component of the active aerodynamics of the Xiaomi SU7. The electric rear wing can provide up to 130 kg of downward pressure during high-speed driving, increase the dynamic limit of the vehicle, and make the body more stable during intense driving.

The average person can't drive at a speed of 200+. Is a new energy vehicle really useful at high speed?

A: The so-called “high speed of new energy vehicles is not important” is a big misunderstanding. Speed performance is an important litmus test for automobile performance and quality.

Higher speed brings acceleration performance and extreme speed performance, while high speed also brings a better and wider efficiency range to the vehicle at medium to high speeds. In addition to extreme speed, we should also pay attention to the energy efficiency of electric drive systems.

Therefore, the SU7 all-wheel drive version still achieves a CLTC range of 800 km under the premise of 0-100km/h 2.78s acceleration and 265 km/h speed, which fully proves that both performance and efficiency can be achieved.

Does the Xiaomi SU7 have real winter test results?

A: The Xiaomi SU7 underwent a complete winter test in Heihe and achieved amazing winter battery life. We are full of confidence to be the king of winter battery life.

Please believe that Xiaomi has invested a lot in the development of thermal management systems. Currently, winter testing is still ongoing. We will explore more technical capabilities. When we optimize and optimize, the results will definitely be even better. Over the past two days, we've shown some actual videos from the winter test, so you can watch them.

Are the detailed configuration parameters of Xiaomi cars currently accurate on major platforms such as Auto Home and Auto Master?

A: There is still some time until the official release of the Xiaomi SU7. Currently, the parameter configurations of the Xiaomi SU7 on various media platforms are not the final version. Please wait patiently for the official release of the Xiaomi SU7.

A lot of configurations were discussed at the press conference. Will the Xiaomi car just be a rough house with many options?

A: First, it's definitely not a rough house. The SU7 is Xiaomi's first car. We built it according to the “one step in place” standard and will put the user experience first. At the same time, in terms of optional equipment, it will definitely satisfy rice fans. In a nutshell, it's“The standard equipment is kind and perfect, and the choice is rich and frugal.”

Does the Xiaomi Su7 have only two versions, the standard version and the MAX version?

A: Through the information previously published by the Ministry of Industry and Information Technology, I believe everyone has also discovered that the Xiaomi SU7 also has a Pro version. We will report specific information about this car to everyone when the product is officially released. Simply put, compared to the standard version, the Pro version's performance will rise another level.

What are the differences in the comfortable configuration between the Xiaomi SU7 standard version and the MAX version?

A: There are differences in configuration between the versions of the Xiaomi SU7, such as air suspension, electric tail, etc. Please wait patiently for the official release of the Xiaomi SU7.

What are the differences between the Xiaomi SU7 standard version and the MAX version in terms of intelligent driving capabilities?

Answer:Regarding smart driving, our goal is very clear: to enter the first tier of the industry by the end of 2024The Xiaomi SU7 Max is equipped with lidar, so in terms of smart driving, priority will be given to installing more cutting-edge advanced and new features, giving users a more advanced choice. Of course, the SU7 standard version's smart driving capabilities are already very strong, which can fully meet the needs of everyday travel. We will also keep up with industry technology trends and continuously improve our smart driving capabilities.

How many city NOAs will Xiaomi open?

A: The goal of Xiaomi's smart driving is to enter the first camp in the smart driving industry by the end of 2024. NOA is currently one of the core directions where various brands focus their efforts on intelligent driving. In 2024, Xiaomi will catch up with the first tier of the industry in terms of the number of NOAs in cities.

What is the partnership between Bangor and Xiaomi?

A: Chris Bangor is one of the top ten most famous car designers in the world and former vice president of design at BMW. He is also the creator of classic designs such as “Angel Eye” and “Flame Curved Surface.” Bangor is currently working as a design consultant for Xiaomi cars. In the future, Bangor will also participate more in the design of Xiaomi's successor models.

Bangor gave high praise to the design of the Xiaomi SU7. He thought “this is a car without excessive design; everything is just right.”

Will Xiaomi later cooperate with third party car companies to launch a similar “smart choice” car?

A: We have no such plans. From the beginning, Xiaomi decided to do full-stack self-research in design, R&D, manufacturing, etc., and that Xiaomi would build cars wholly-owned and at its own risk. This is not only Xiaomi's determination to build a car, but more importantly,We believe that only wholly-owned vehicle construction and full-stack control can control the quality and user experience of every aspect of the car.

Will the Xiaomi Pengpai OS car system be opened for use by third party brands?

A: Xiaomi Surge OS is a closed loop operating system for the entire ecosystem of people and cars. Taking the Xiaomi SU7 as an example, the real-time state of the vehicle can be displayed without delay on the vehicle side; devices such as mobile phones and tablets can flow seamlessly with the vehicle all require the support of comprehensive software, hardware, and ecology capabilities.

We have also reserved a wealth of standard software and hardware interfaces, and welcome third-party apps, eco-accessories and other brands to join the entire ecosystem of Xiaomi cars.

How is the car app experience for Xiaomi cars?

A: A large part of the intelligent experience of new energy vehicles comes from the fluency and degree of humanization of vehicle interaction, as well as the richness and maturity of the application and service ecosystem. And this is exactly our field of expertise. In-car screens, including our large central control ecological screen, can directly apply the Xiaomi Pad application ecosystem, and have an extremely powerful and innovative handcar interconnection experience.

Of course, the Pad app must guarantee the experience. If you select one by one, the experience meets the standards before it is suitable for boarding. We have also done a lot of work to adapt to different working conditions to ensure the completeness and fluency of the user experience. I believe everyone will feel relaxed and cheerful after the experience.

What are the current adaptations for Xiaomi SU7 car applications?

A: The Xiaomi SU7 car has the richest application ecosystem in the industry at present. 5000+ Xiaomi tablet apps will gradually adapt to the car. At the same time, you can also use the mobile app Pin to become a native app in seconds.

What communication protocol does the standard pin point interface reserved by the Xiaomi SU7 use? Can other devices such as video interfaces be expanded?

A: The Xiaomi SU7 has reserved a standardized pin point interface, and we also hope that third party brands and developers will work together to build the Xiaomi Cariot ecosystem. We will report in detail on the expansion of the PIN point and the Cariot ecosystem when it is officially released.

Does the Xiaomi SU7 Standard Edition come with HUD features as standard?

A: There are configuration differences between the versions of the Xiaomi SU7. Please wait patiently for the official release of the Xiaomi SU7 for specific information.

Which 5 screens are included in the 5 screen linkage of the Xiaomi SU7? Are they all standard?

A: The five-screen linkage car system of the Xiaomi SU7 MAX version includes a flip instrument screen, HUD head-up display, a large car screen, and 2 expandable rear panel screens. Among them, the rear row expansion screen is not standard.

Will the current Xiaomi CarWith be updated? What features on Xiaomi cars will be devolved to Carwith?

A: Xiaomi CarWith will continue to be updated, and our goal is for as many people as possible to enjoy itA “full ecosystem of people, cars, and families” experience.

Is CTB battery maintenance expensive? Will the life of a car be equal to the life of a battery?

A: The Xiaomi SU7 uses CTB integrated battery technology. Compared with traditional solutions, it has higher battery volume efficiency, which further frees up the passenger compartment space of new energy vehicles. At the same time, CTB technology can optimize vehicle safety, and has greatly improved torsional stiffness and vehicle NVH.

In particular, CTB only integrates the battery compartment cover with the passenger compartment floor. Under extreme circumstances, the battery pack can still be easily removed for maintenance, ensuring high maintenance efficiency and low maintenance costs.

Xiaomi Auto CTB batteries claim that the volumetric efficiency of 77.8% is the highest in the industry, but some netizens claim that the volumetric efficiency of their self-developed batteries has reached 80% or more. What happened? Is Xiaomi bragging?

A: Xiaomi's CTB battery pack, with a volume efficiency of 77.8%, is the ceiling of the current CTB solution battery. The Youshang battery mentioned in the question does not use CTB technology, so there is little point in directly comparing these two items.

Because CTB technology integrates the passenger compartment floor and can effectively free up passenger cabin space, the two designs cannot be reflected through simple volumetric efficiency. The integrated battery technology of the Xiaomi CTB has also secured more vertical space optimization for the vehicle.

For comparison, the overall volume efficiency including the battery pack+passenger compartment floor and related sub-components needs to be calculated in a consolidated manner. We have not yet carried out relevant horizontal comparative calculations, so we can ask professional evaluation media to conduct actual measurements in the future.

A: The Xiaomi SU7 Max uses a dual-motor four-wheel drive design.Maximum power 673 horsepower, peak torque 838 N·m, zero hundred acceleration to 2.78s(Acceleration score minus starting response time), surpassed the Porsche Taycan Turbo and entered the 2s supercar club.

In addition to its excellent acceleration capabilities, the Xiaomi SU7 also has an outstanding speed level, with a top speed of 265 km/h. Previously, the tram industry was generally unable to achieve both acceleration and extreme speed, but the Xiaomi SU7 proved that this is entirely possible.

Accelerating so fast, and the speed is so high, how is the braking ability of the Xiaomi SU7?

A: The Xiaomi SU7 Max uses Brembo front four-piston brake calipers customized by Xiaomi, which not only accelerates quickly but also brakes steadily. The 100km/h-0 braking distance is only 33.3m, which is the best in its class. The Xiaomi SU7 standard version has a 100 km braking distance of 35.5 m, which is also excellent.

How can the Xiaomi SU7 ensure that it can stop and stop steadily?

A: In order to ensure that the braking system of the Xiaomi SU7 is foolproof, we have adopted a quadruple braking redundancy strategy: if the brake pedal is stuck, you can press the P gear for a long time to decelerate; if a single braking unit fails, the DPB and ESP can back up each other; if the DPB and ESP fail at the same time, we can still rely on traditional mechanical hydraulics to brake normally.

Even in case of an emergency, under the extremely low probability, the above 3 brakes will all fail, the kinetic energy recovery of the Xiaomi supermotor is also a layer of guarantee for Xiaomi's braking redundancy. The maximum deceleration of 0.36g allows the vehicle to brake quickly.
