Xiaomi’s press conference is never boring, thanks to Lei Jun’s interesting speech.

I thought that Xiaomi’s trip was to share the technical details about Xiaomi’s car. Lei Jun, who first suppressed and then promoted, always brought unexpected things. On the one hand, the popularization of new energy vehicle technology is easy to understand, and Mr. Lei has brought the "pre-release" of Xiaomi’s first model SU7 without stint.

Even if the new energy vehicle market is seriously involved, Xiaomi is under great pressure, and Lei Jun in the speech still smiles with confidence.

You can’t give too many surprises. Xiaomi’s brand is not much different from that of traditional car companies. The price that everyone wants to see most is naturally absent, and a press conference can’t be finished.

Even if there is no price, the content of Xiaomi Automobile Technology Conference is worth taking out and talking about.

When the super motor arrived, the latecomers also had great ambitions.

In order to make it easier for us to understand the system engineering of electric vehicles, Lei Jun divided the technology of Xiaomi Automobile into five parts.

The core technology of the fuel vehicle era is the engine, and when it comes to new energy vehicles, it is the motor. Xiaomi’s two brand-new super motors made their debut, namely V6 and V6s, both of which can reach the maximum speed of 21,000 rpm. The reason why it is called V6, Lei Jun thinks it can be compared with V6 engine in the fuel car era.

It is not unusual for a motor with 21,000 rpm to be put into use today. The high-performance motor carried by Krypton 001 FR can "overclock" the maximum speed to 24,000 rpm. Lei Jun was puzzled by "being cut off" and admitted that this was the direction of the industry, but he still found the answer of "far ahead".

Higher peak power and greater torque are the "kings".

Lei Jun said that Xiaomi Automobile has a more powerful "V8s" super motor in the pre-research, and its maximum speed reaches 27,200 rpm. A single motor module can provide power comparable to the V8 engine, with a peak torque of 635 Nm and an efficiency of 98.11%.

This "horrible" motor will land in 2025, but Xiaomi has bigger ambitions.

"Cake painting" is a common phenomenon in the automobile industry. The release of a car is divided into several steps, and there is also a certain period from finalization to delivery. Lei Jun believes that pre-research is an important measure of technical reserve and has to be done. In addition to the V8-comparable motor, Xiaomi also has a super motor based on carbon fiber laser winding technology. The speed of laboratory test has exceeded 35,000 rpm, but it will take some time for mass production to land.

As a latecomer, Xiaomi Automobile has spared no effort in technical reserve, improved motor technology through self-research, and its book data is ahead of its peers, which is the most intuitive performance that consumers can feel. We don’t know the actual performance, and the means of Xiaomi roll parameters are well known in the field of smart phones.

At least, Xiaomi has won Tesla and Porsche from the perspective of parameters.

Self-developed battery in place, durable and safe.

Power battery is the cornerstone of electric vehicle, and it is also one of the core components.

Xiaomi can’t research batteries by himself, but the battery pack has the ability to research independently. The power battery on Xiaomi’s first model is the result of two years’ cooperation with the world’s leading battery suppliers. Of course, it also supports the mainstream 800V high-voltage platform, and the highest peak voltage reaches 871V V. Lei Jun smiled and said that this should be called "quasi-900V".

He also used this to ridicule a wave of "industry status quo". He revealed that as long as it is 500V and 600V, it can be called "800V" on the table. In contrast, he wants to make products honestly.

CTB integration technology is a highlight of Xiaomi’s self-developed battery pack. This design can integrate the battery pack with the automobile chassis, on the one hand, improve the strength of the whole vehicle structure, on the other hand, reduce the thickness of the bottom plate and leave space for the cockpit.

Improving the battery volume utilization rate and greatly reducing the number of wire harnesses have significant advantages for the battery life and safety of Xiaomi automobile. Lei Jun revealed that the battery capacity of Xiaomi’s first car is as high as 101kWh, and the cruising range can reach 800 kilometers, which has both long battery life and fast charging.

Thanks to the advantages of platformization, Xiaomi’s self-developed battery pack can theoretically achieve a capacity of 150kWh and its battery life can be increased to 1260 km. However, the biggest problem with ultra-large capacity batteries is the cost and difficulty in mass production. Lei Jun also admitted that the cost price of such a battery should be at least 100,000.

Of course, the battery pack also has other results brought by Xiaomi’s self-research. The battery cell inversion technology is the first in the industry. After the battery cell is hit, it can quickly release energy to the ground, minimizing the negative impact of thermal runaway. At the same time, Xiaomi also added 165 pieces of aerogel insulation materials to the battery pack, and with a series of safety measures, the safety factor of Xiaomi battery pack was several times higher than the industry standard.

As a newcomer to the car track, Xiaomi’s definition of the first car is advanced enough. Starting from the 800V platform, CTB integrated battery pack technology is the mainstream development direction of electric vehicles in the future. Considering the discount of winter battery life, Xiaomi also came up with his own solution.

High-efficiency dual-mode heat pump technology is an improvement of Xiaomi’s heat pump. In the bad weather below zero, it can take into account the heating of the battery and the cockpit at the same time, so as to keep the battery in the best working condition at all times, thus alleviating the trouble of battery life discount.

Late entry has the advantage of late entry, the most obvious of which is "less detours". The new forces who joined the ranks of car-making before have found out the way for these latecomers, and they have reduced the cost and time wasted in many exploration processes. Xiaomi Auto has proved itself with various advanced technologies. Even if it is a new player, its technical content is no less than that of its peers, and it also has mature solutions.

It is obviously the right choice to dispel consumers’ doubts about Xiaomi Automobile from the technical force.

Super die casting, the future of the automobile industry.

Xiaomi is one of the few Internet companies that build cars by self-built production lines, and will have its own factory to produce battery packs in the later period.

Therefore, Lei Jun specially spent some time to introduce the breakthrough of Xiaomi Automobile in production line technology.

Die-casting technology is the representative of the industrial level of car-making enterprises. Lei Jun said that at present, the die-casting machine of Tesla American factory has a clamping force of 9000 tons. Xiaomi’s super-large die-casting equipment cluster, the locking force is one level ahead of Tesla, reaching 9100 tons.

Nine processes, 60 equipments, 433 process parameters, 840 square meters of floor space and 1,050 tons of total weight are the most intuitive parameters of Xiaomi Super Die-casting Equipment Cluster. This is more indicators that Xiaomi can come up with besides the clamping force, which seems to ridicule a wave of colleagues who only roll the clamping force.

Greater clamping force means that Xiaomi can manufacture die-casting structural parts with higher structural strength and more precision, and can also integrate more parts through integral die-casting in exchange for higher strength and lower production cost. However, the maintainable space after high-speed collision is still a big problem faced by integrated die casting. Xiaomi automobile, which is determined to redefine the future automobile industry, believes that it also has its own set of solutions.

After all, electric vehicles are highly dependent on integration. The higher the integration, the more space they give users, and more places can be reserved for high configuration.

What is the finishing touch to the safety of Xiaomi automobile should be Xiaomi Titan alloy. Lei Jun introduced that this is Xiaomi’s ability to find the best formula from 10.16 million schemes with the help of AI, and called it Titan alloy. With Xiaomi’s advanced production line, it can be said that the structural safety of Xiaomi automobile is no longer in doubt.

All this is also the result of Xiaomi’s painstaking efforts.

Intelligent+intelligent driving, laying the "moat" of Xiaomi automobile

Mobile phone manufacturers are best at interaction and intelligence, and Xiaomi has a natural advantage in this field.

We got the answer from the existing smart cockpit solutions in the market. They have more experience in the field of smart cars than traditional car companies, know how to build an efficient and practical interactive system, and use their own intelligence and ecology to open up a track different from traditional car companies.

Whether it is intelligent cockpit or intelligent driving, Xiaomi chooses full-stack self-research and uses intelligent algorithms to create the "hardest spear" for Xiaomi car. For the field of intelligent driving, Xiaomi has launched "Zoom BEV", "Super-resolution Occupancy Network" and "Road Large Model". There is only one result of the combination of the three-very cow.

"Zoom BEV" enables vehicles to have the same ability as human eyes, adjust the focal length for different scenes, and can "see accurately" on narrow roads and "see far" on high-speed roads. Lei Jun made a big show at the press conference. Xiaomi SU7 can accurately park in a very narrow mechanical parking space, and its technology is comparable to that of an old driver.

"Super-resolution occupation network" and "road large model" are technologies to enhance the cognitive ability of the system, which enable Xiaomi to judge the small bullying obstacles on the road more accurately, and carry out AI correction on some parts that are wrongly identified to enhance the vehicle’s cognitive ability.

At the press conference, Lei Jun also showed everyone the intelligent driving strength of Xiaomi Automobile.

Lei Jun said that the mechanical quality of domestic cars has reached a high level. Armed with intelligence in every corner of the car, relying on software to define the chassis and enhancing the car’s ability through OTA are the outstanding points of domestic smart cars. Some peers, Xiaomi is doing better, and what peers don’t have, Xiaomi can take it out.

The intelligent cockpit is the home of Xiaomi. Lei Jun said at the press conference that Xiaomi SU7 will be equipped with a "Pad" class car screen with an amazing resolution of 3K, and it has achieved "leading generation" in the degree of freedom of touch, hand and car linkage and animation display.

Then, the industry’s first "120Hz", will it happen on Xiaomi car?

Xiaomi’s mobile phone gives the on-board 澎湃 OS a higher upper limit. On the one hand, it allows the car to directly call the App on the mobile phone. With the silky split-screen design, the flexible experience is a "dimensionality reduction blow" to traditional car companies. Thanks to the 8295 chip, Xiaomi can drive more display screens, including connected tablet computers.

Of course, Apple users can also have a good experience.

By the way, Xiaomi has also developed a special interface standard for cars, which allows vehicles to connect to a large screen and even add a row of physical buttons. With the gradual improvement of Xiaomi CarIoT, I believe that Xiaomi Automobile can become more flexible and practical by relying on this set of interface standards.

Here, the first half of Xiaomi Auto Technology Conference is over.

Xiaomi SU7 "pre-released", to be a "future classic"

"The classic image in the history of automobile manufacturing is still a car", which is Lei Jun’s consideration of Xiaomi’s first car.

Lei Jun always likes to give us small surprises. When warming up, he said, "Only technology is released, but no products." As a result, the second half of Xiaomi’s auto technology conference was the world premiere of Xiaomi’s first car SU7.

Careful people may find some "eggs". Two Xiaomi SU7s who came to the scene did not have an operator in the driver’s seat, but went on stage by themselves, which was quite interesting for the intellectual S7 to appear on the stage, and also made a wave of advertisements for the intelligent assisted driving of Xiaomi Automobile.

At the beginning of Xiaomi SU7 exposure, the capable and avant-garde design attracted many people. The lines of Porsche Taycan (parameter picture) are not in line with the mainstream design language, which may not look good at first glance, but Lei Jun hopes to have a design that can stand the test of time and stimulate people’s driving desire.

To this end, the design lineup of Xiaomi SU7 is extremely luxurious, and many of the design teams are former BMW chief designers.

The semi-hidden door handle with full practicality is less "ceremonial" and more "light" for opening the door. Even so, the drag coefficient of Xiaomi SU7 is controlled at 0.195cd, which is the top level in the automobile industry. Lei Jun’s statement is also very simple, not because the doorknob is frozen in winter, but because the hidden doorknob is often put away, so it is not easy to clean it at ordinary times.

Chris bangle, one of the top ten most famous car designers in the world, believes that Xiaomi SU7 is not over-designed.

If the design of this car can be regarded as a representative for more than ten years or even decades, it will become a classic in the future. Just a design is enough for Xiaomi to spend more space to introduce.

But good-looking is only the "first impression" of Xiaomi SU7, and good-looking design is not enough to support the three-dimensional sense of the product. Lei Jun has repeatedly stressed that SU7′ s products are very powerful, not 99,900 yuan and 149,900 yuan.

At the scene, Lei Jun announced two versions of SU7, but mainly the "Max" version, equipped with dual motors, with a maximum output of 673 horsepower and an acceleration of 2.78 seconds. The cruising range is 800 kilometers, and it has dual Orin chips and customized lidar. At the same time, SU7 also has the largest front reserve box capacity at present, with a full 105 liters, which is enough for fishing enthusiasts to "take off in situ".

Moreover, Xiaomi has made its multi-device ecological moat more extreme. SU7 can not only be linked with Xiaomi’s mobile phone, but also establish contact with more IoT devices through Mijia Ecology.

The price of the standard version may have a good price, but it is far from the configuration of the Max version. I wonder if a compromise version will be launched in the future. The Max version of the product is very powerful, and the actual price may not be low. This will have to wait for the first half of next year, and Lei Jun will answer it for you again.

Lei Jun’s "last step" has no retreat.

"This is the last time in my life to start a business. Xiaomi Auto has taken this step and can’t go back."

It has been 1003 days since Xiaomi officially announced the construction of the car. Lei Jun didn’t have many exciting stories at the end of the press conference, and he didn’t have the firepower to mark friends. He just said that Xiaomi had redoubled his investment to do a good job in the automobile business. Obviously, SU7 is a beautiful start for Xiaomi’s automobile business and a perfect turn for Xiaomi.

Without a solid reputation and profound automobile manufacturing background, it is more difficult for internet companies to step out of the comfort zone and enter the automobile manufacturing track than ordinary car companies. The new forces that challenged the traditional automobile industry have also experienced such challenges, so it is not difficult to understand why Xiaomi should pay tribute to these "pioneers".

However, the Internet brand represented by Xiaomi has the colors needed by smart cars. Electrification, intelligence, deep integration between cars and smart phones, efficient interaction between intelligent cockpit systems, and advanced intelligent assisted driving systems ….. all these have more desirable experiences in Internet companies.

These characteristics are not available to traditional car companies, and it is even more difficult to catch up in the short term.

The technical conference of Xiaomi Automobile was very long. During the whole three hours, Lei Jun brought us a lot of dry goods about Xiaomi Automobile. The core of the technical conference was to show the strength of Xiaomi Automobile to the outside world and meet the expectations of potential customers. After 15 to 20 years of hard work, Xiaomi has become the top five automobile manufacturers in the world. In this increasingly prominent automobile market, Xiaomi has its own self-confidence and pursuit.

By the way, Lei Jun also became a "lecturer" on new energy vehicles, popularizing a wave of parts and technical principles of electric vehicles. The popularization of knowledge may also be integrated into the service chain of Xiaomi Automobile.

In Lei Jun’s view, the future car should be a beautiful, easy-to-drive, comfortable and safe "mobile smart space". Can Xiaomi car, which started the revolution, be the protagonist of the "Smart Car 4.0" era?

In the last few days of 2023, Xiaomi made people remember with the biggest stride in its historical process. SU7′ s next appearance should be at a major international auto show next year. We are still looking forward to the final price of SU7. After all, in the field of mobile phones, the stacking and pricing of Xiaomi has always been very conscientious.

Lei Jun’s "Dream Car" has arrived, so is SU7 the "Dream Car" beyond Porsche and Tesla in the mind of rice noodles?
