Lei Jun: The price of Xiaomi car has not been fixed, but there is no rival within 500,000 yuan, and there is no "beggar in the middle" version.

Lei Jun: The price of Xiaomi car has not been fixed, but there is no rival within 500,000 yuan, and there is no "beggar in the middle" version.

On December 28th, 2023, Beijing and Xiaomi held the Xiaomi Automobile Technology Conference, and the first model of Xiaomi Automobile "Xiaomi SU7" was displayed on the screen. Vision china diagram

Xiaomi car, which has not disclosed the official price, is still the focus of public opinion.

On January 8th, Lei Junfa Weibo, founder of Xiaomi Group, said that for Xiaomi Automobile, friends are concerned about many topics, and they will focus on answering the most typical 100 questions, which will be answered separately in three days.

"This time we just held an automotive technology conference, and the heat was so high that it exceeded our expectations. On the one hand, the huge heat represents the user’s expectation of Xiaomi car, and we are really happy. On the one hand, a large number of false information, rumors and malicious smears are also swarming. We will clarify in time, and we will resolutely pursue the legal responsibility of those who make rumors and smear. " Lei Jun said.

On December 28th, 2023, Xiaomi held the Xiaomi Automobile Technology Conference in Beijing, and Xiaomi SU7, the first product of Xiaomi Automobile, made its first public appearance. This model is positioned as a C-class high-performance coupe, and it is planned to be mass-produced in the first half of 2024. In addition, this conference officially revealed the breakthroughs in the five core technologies of Xiaomi Automobile, including key areas such as electric drive, battery, large die casting, intelligent driving and intelligent cockpit.

At the press conference, Xiaomi SU7 was almost spoiled, but the price remained mysterious, which became the focus of hot discussion.

For the price of Xiaomi car, Lei Jun once again stressed that it will not be 99,000, 149,000 or 199,000. The final pricing will be announced at the official press conference of Xiaomi SU7. "The prices of Xiaomi cars on the Internet are all false news, and we have not yet determined the final price."

There are also many netizens who are curious about whether the seemingly "expensive" Xiaomi SU7 will launch a low-end version, such as the "beggar-in-the-middle" version or the "Redmi version". In this regard, Lei Jun said that Xiaomi Automobile has a fully consistent product project criteria, and "experience priority" has always been put in the first place. Xiaomi SU7 is the standard version, and there is no plan to launch Redmi Automobile at present.

For the color of Xiaomi SU7 to be released in the future, Lei Jun revealed that more colors will be extrapolated beyond the disclosed Gulf Blue, Olive Green and Elegant Grey.

Previously, Lei Jun replied in the comments of netizens, "Is there an opponent within 500,000 (Xiaomi Automobile)?" In this question and answer session, Xiaomi reiterated that although this is a joke, it is also serious. "We are pragmatic and will not set those outrageous flag, so we are still very confident that Xiaomi SU7 has no rivals within 500,000 at present."

As for Lei Jun’s recent time allocation, Xiaomi responded in the Q&A that Lei Jun is still very concerned about the technology research and development of the mobile phone business. At this stage, his time and energy allocation is roughly as follows: at least 1/4 time is still spent on the mobile phone research and development business, 1/4 is concerned about the operation and management of the group, and 1/2 time is spent on the automobile business.

[The following is the full text of the question and answer]

1. A lot of rice noodle feedback. There are so many rumors about Xiaomi Automobile recently. Does Xiaomi Legal really have a job? When will the relevant progress be announced?

This time, we just held an automobile technology conference, and the heat was so high that it exceeded our expectations. On the one hand, the huge heat represents the user’s expectation of Xiaomi car, and we are really happy. On the one hand, a large number of false information, rumors and malicious smears have swarmed in, and we will clarify them in time, and we will resolutely pursue the legal responsibility of those who spread rumors and smears.

2. What is the pricing of Xiaomi Auto SU7? When will it be announced?

We really haven’t set a final price yet. Mr. Lei also introduced it at the Xiaomi Automobile Technology Conference. It is indeed a bit expensive, but it will be "expensive for a reason".

Not 99,000, not 149,000, not 199,000. The final pricing will be announced at the official launch conference of Xiaomi SU7.

3. There is a lot of news about the price of Xiaomi car on the Internet. Is it true?

The selling prices of Xiaomi cars are all false news, and we haven’t determined the final selling price yet.

The final selling price will be announced when Xiaomi Automobile is officially released.

4. Is the main content of Xiaomi SU7 basically finished?

On December 28th, 2023, the technical conference of Xiaomi Automobile was held. This time, we only introduced the five core technologies of intelligent electric vehicles, and the products are only a brief introduction. We still have a lot of technologies and product contents that have not been developed. I will introduce it to you in detail at the official conference of Xiaomi SU7.

5. Is the greater the pressure, the better? Why is Xiaomi die-casting 9100t?

What we often talk about here is the clamping force of large die casting. The determination of clamping force is designed by die casting. After millet integrated die casting, the floor is larger and more complex than Tesla Model Y, so the rated clamping force of 9100t is finally selected. In actual use, the maximum clamping force of millet under super high pressure is 9500t, and the stable value can reach 9300t t.

Clamping force is not the only index of large die casting technology. The properties of heat-free alloy raw materials, die-casting island cluster design, defect detection and so on are the core indexes to measure the large die-casting technology. Xiaomi is currently the only car company in the world and the only one in China with self-developed heat-free alloy materials and self-developed large die-casting island clusters.

6. Someone on the Internet said that Xiaomi’s big die casting was directly renamed from Haitian’s existing 8800t die casting machine. Is this true?

Of course not. Xiaomi Super Die-casting is 9100t (ton), which is not the model, but the actual rated clamping force. In fact, the clamping force of Xiaomi Super Die-casting Cluster in normal operation can reach 9500t. It is worth noting that Xiaomi’s super-large 9100t die casting machine was jointly developed by Xiaomi and Haitian. Based on the existing die casting machine technology, Xiaomi’s R&D team carried out 11 patent design innovations, most of which were invention patents, such as A I actively optimized the injection parameter setting system. But the die casting machine is only a link. Xiaomi has developed the whole die casting cluster system, including 60 equipments and 433 process parameters. For details, please click this link: Learn about Xiaomi Super Die-casting Cluster.

7. If it really hits a large die casting, how high is the maintenance cost of Xiaomi?

The tail of Xiaomi SU7 adopts a three-stage design, and the buffer zone is designed on the basis of the integrated large die-casting floor. Conventional collision only needs to replace the buffer collapse zone, and the maintenance cost is the same as that of the traditional design. When encountering extremely high-speed collision, the integrated large die-casting floor can provide better safety protection.

Generally speaking, the integrated floor design of Xiaomi SU7 after large die-casting is: the maintenance cost of small collision is not painful, and the big collision is stronger to protect your safety. It is the best solution at present.

8. Is the yield of millet die casting high? Will it bring quality problems if you use large die casting as soon as you come up?

Large die casting technology is a typical long-term technology, and it is also a ticket for future head car companies. From the very beginning, Xiaomi Automobile decided to research the whole stack and invest in two sets of die-casting island clusters at one time. In order to ensure foolproof, we also added a set of traditional stamping schemes at that time, and three schemes were done at the same time. Finally, the Xiaomi Super Die Casting Project landed smoothly.

At the same time, our self-developed technologies related to large die-casting island include temperature control system, aluminum liquid transfer system, injection system, pouring and drainage system, etc., and through our self-developed AI defect detection system, we can ensure the yield of millet SU7 integrated large die-casting floor.

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

Xiaomi Titan alloy is excellent in die-casting performance, mechanical properties, durability, recyclability, economy and so on. Xiaomi Titan alloy is also added with 40% recycled aluminum, which is very environmentally friendly. Xiaomi has become the only automobile manufacturer in China and the only one in the world with mass-produced self-developed large die-casting materials. As for why the alloy materials were developed by ourselves at that time, I also talked about it at the press conference. It was because the requirements of large die casting for alloy raw materials were extremely harsh. At that time, the supplier’s formula could not meet our requirements, so we had to develop the materials by ourselves. The cost of self-developed materials was definitely much higher than that of directly using mature schemes.

10. Is Xiaomi Titan alloy really self-developed?

Yes Some netizens may have been misled by the wrong information before. What everyone saw was the chat record of Professor Yang of a university. In fact, Professor Yang quickly clarified it. Praise for Professor Yang’s spirit of seeking truth from facts, and also regret the misunderstanding caused by it. I hope everyone can help me forward and clarify.

11. What’s the difference between the specific formula of Xiaomi Titan alloy?

Related patents have been publicly available, and the proportion of eleven elements used in the alloy has also been disclosed. (Patent number ZL 2023 1 0604165.9)

12. How much of the Xiaomi super motor series is self-developed?

We have officially released three types of motors, and at the same time disclosed a pre-research motor that has been experimentally realized. Among them, Xiaomi super motors V6 and V6s are jointly developed with UMC and Huichuan respectively, with a rotating speed of 21,000 rpm. At the same time, Xiaomi has developed the Xiaomi super motor V8s with a speed of 27,200 rpm, and this information has also been publicly disclosed by Huichuan on the interactive platform of A-share investors.

13. Is Xiaomi Motor V6 an old product of UMC? Why are the models and names the same?

Xiaomi motor V6 is a brand-new motor jointly developed by Xiaomi and UMC. Through the joint efforts of both parties, the stress topology structure of the motor rotor has been improved, and the speed and power density of the motor have been greatly improved, and relevant patents have been obtained.

The so-called "Xiaomi Motor V6 is an old model motor of UMC TZ220XS000 in 2020" is purely a rumor. TZ220XS000 is named only for national standard rules: TZ stands for permanent magnet synchronous motor; 220 represents the outer diameter of the motor; X represents a resolver position sensor; S stands for water cooling and heat dissipation; 000 is the brand code of UMC. The same internal name does not mean the same motor, which can be known from the publicly available information in the industry.

14. Is the V8s motor mass-produced?

The V8s has been mass-produced and will be put on the train in 2025. At present, some automobile evaluation media have measured the engineering vehicles loaded with V8s motors, and the measured V8s speed can reach more than 30,000 revolutions. However, the relevant test is the limit test, and the rated speed of V8s is still calibrated at 27,200 rpm.

15. How did Xiaomi’s super motor achieve a high speed of 35,000 rpm? Xiaomi was more powerful than Tesla for the first time.

Behind the high speed of 35000rpm, there are many innovative efforts in structural design, material technology and so on. Among them, the most important thing is that Xiaomi used "laser in-situ curing carbon fiber winding technology" to carry out innovative design of rotor sleeve of high-speed motor, and obtained relevant authorized rotor patents.

Compared with the wet winding method of carbon fiber, which requires brushing resin for curing after carbon fiber winding; In the laser in-situ curing winding process of millet, carbon fiber prepreg tape is used instead of carbon fiber precursor and resin glue, and the curing of carbon fiber prepreg tape is realized by laser while winding on the same station equipment. The process is simple, one station is completed, and the tension is directly maintained during the winding process.

16. Is CTB inverted battery really the first in the industry?

The battery core is inverted, which has happened in the industry; The pressure relief valve is inverted, which has happened before. However, the CTB battery cells which are inverted at the same time have never been inverted before. This technical solution pioneered by Xiaomi is to ensure the ultimate battery safety and the ultimate space utilization.

CTB is Cell to body, which is the design ability of automobile manufacturers. It is not only the technology of battery manufacturers, but also the integration of battery pack and body. The upper cover of battery pack is directly the floor of passenger compartment. Xiaomi has 36 core patents. The structural design of CTB integrated top cover, side wall design, bottom protection and composite fiber backbone are all designed by Xiaomi. The low conductivity coolant, battery management software, Che Yun integrated safety early warning system and high voltage architecture are also designed by Xiaomi.

17. What specific benefits can Xiaomi CTB inversion technical scheme bring?

Xiaomi CTB battery pack adopts the inverted battery cell design. Compared with the traditional upright battery cell, the pressure relief valve faces downwards. With the only nonporous high-strength steel upper cover design in China and the most stringent thermal runaway safety standard in the world, the passenger compartment is completely isolated from the battery compartment in the limit state.

Even if the heat is out of control at 55 degrees Celsius, there is no open flame and heat spread, and the pressure relief valve is facing down and the cover is non-porous, which constitutes the ceiling of the battery safety protection ability.

18. How high is the aerogel content of Xiaomi battery? Is it standard?

Xiaomi SU7 adopts the industry’s top 17 layers of high-voltage insulation protection, and customizes the strongest active cooling technology in the industry: the cooling area of double large surfaces reaches the highest level of 7.8m2, which is four times the industry average. At the same time, 165 pieces of the most advanced aerogel insulation materials in the industry are laid on both sides of the battery cell, which can resist the high temperature of 1000°C at the highest.

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

19. Some netizens wonder whether the thermal management of Xiaomi SU7 can only reach -20℃ because it can adapt to low temperature. Is this true?

At present, there is no strict specification about the working scope of heat pump in the industry. Some enterprises claim that it can be as low as -30℃, but it is not a pure "air source heat pump", but a heater or water source heat pump is working.

It was revealed at the Xiaomi Automobile Technology Conference that -20℃ relies on a pure air source heat pump and can still obtain heat from the air.

If we follow the same caliber of the above-mentioned related companies and add heaters, the overall thermal management ability of Xiaomi Automobile can be as low as -30℃ or even lower. Therefore, Xiaomi automobile can challenge the "king of winter trams", and it can be said that "trams have no fear of winter".

20. Is the Modena platform of Xiaomi Automobile completely self-developed?

The Modena platform of Xiaomi Automobile is a self-developed automobile platform of Xiaomi. There have been rumors that Xiaomi Automobile uses other car factory structures, which is completely inaccurate.

100 "first", "only" and "most" design goals were established at the beginning of the research and development of the modena platform of Xiaomi Automobile. Some achievements were also shared with you at the Xiaomi Automobile Technology Conference, and there are still more achievements. We will report to you in detail when Xiaomi Automobile is officially released.

21. Have you actually achieved the design goal of "100 first, only and most"?

We talked about "design goals" at the press conference. In fact, most of them have been achieved. Because of time constraints, we only talked about some of the leading technologies and functions of Xiaomi Automobile. More points, we will introduce to you in the future until the official release of SU7.

22. What can Xiaomi’s intelligent driving achieve the goal of "entering the first camp in the industry in 2024"?

The intelligent driving of Xiaomi automobile adopts a full-link self-research scheme. Moreover, the starting point of Xiaomi is very high. Based on the latest generation of the underlying algorithm-BEV+Transformer+occupation network, the large model technology is fully integrated into it, and the end-to-end perceptual decision-making large model is applied to the production car for the first time in the world.

23. Xiaomi SU7′ s elk test score of 82km/h is based on what standard?

Xiaomi SU7 elk test was carried out in full accordance with the international standard ISO 3888-2, and the elk test score was 82 km/h. If you are careful, you will find that the road width in the middle section of the test is slightly narrower than the national standard, which makes it extra difficult for yourself. Elk test is a comprehensive test that reflects a series of capabilities such as handling and body stability. After Xiaomi SU7 is officially listed, the media are also welcome to compare and measure it.

24. Will Xiaomi make a beggar-in-a-beggar version in order to lower the starting price?

Please rest assured that Xiaomi Automobile has fully consistent product project criteria, and "experience priority" is always in the first place. Xiaomi SU7 is the standard version.

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

No matter which version of the car, the safety crash test results are top-notch. We chose the most stringent standards to design our products. Xiaomi SU7 series has reached the five-star safety standard of C-NCAP 2024, the five-star safety standard of E-NCAP 2023 and the excellent safety standard of C-IASI 2023 3G+.

26. Does Xiaomi car have only three colors? Will the production version have white and black? Will there be macho powder?

This time, we announced three colors of Xiaomi SU7, namely Gulf Blue, Olive Green and Elegant Grey. All three colors are very beautiful on the real car. Our design team has made great efforts in color research and development and car paint technology.

We also see many users asking if there is a classic black and white color scheme. We do have more colors to choose from, which will be fully introduced to you when it is officially released.

27. Why didn’t Xiaomi consider redesigning a new car logo?

We are very satisfied with the logo design of Xiaomi Automobile, which is in the same strain as the Xiaomi brand logo. It is our important brand asset, and aesthetics is a subjective matter. We will also listen to your different voices with an open mind.

28. Why was the first car called Xiaomi SU7?

"SU" is the abbreviation of Speed Ultra, and "7" is the series positioning determined according to the usual cognitive habits of vehicle positioning in China. The size of the vehicle is about the same as that of BMW 5 Series. High performance is Xiaomi’s gene. Tesla said not to build a slow train, and we did the same. As for how to pronounce it, we also discussed it seriously internally. In the end, everyone thought it would be called "Su 7", just like calling a friend’s name, which is more cordial.

29. Will Xiaomi SU7 be sold globally?

At present, we will focus on the official release and listing in China. But our ultimate goal is to make Xiaomi cars gallop on every street in the world.

30. Will Redmi cars be launched in the future?

Without this plan, at present, we are still focusing on the whole chain of production and sales of Xiaomi car, even specifically, our first car, Xiaomi SU7.

31. When can I see the real car of Xiaomi car in the Xiaomi home around me?

After the official release of Xiaomi SU7, we will provide you with a real car experience in Xiaomi Home in key cities across the country. We are actively preparing for this work, and please wait patiently for a while.

32. Mr. Lei said that Xiaomi had no rivals within 500,000 yuan. Was it a joke or serious?

This is a sentence that General Lei replied to netizens in the comment area at that time. Although it was a joke, it was also serious. At the press conference, we made a number of comparisons including design/performance/endurance/vehicle safety with Porsche Taycan Turbo/ Tesla Model S. The actual comparison results are very clear to everyone, and the pricing of these two cars is also very clear to everyone. We are pragmatic and will not set those outrageous flag, so we are still very confident that Xiaomi SU7 has no rivals within 500,000 at present.

33. Is General Lei focusing on building cars? Do you still have the energy to build a good mobile phone?

Mobile phone is still the core business of Xiaomi and the core foundation of our strategy of "people, cars and homes are all ecological". Mr. Lei is still very concerned about the technology research and development of mobile phone business. Last year, Mr. Lei said that at this stage, his time and energy distribution is roughly that at least a quarter of his time is still spent on mobile phone research and development business, a quarter is concerned about group operation and management, and a half is spent on automobile business. ????
