Xiaomi's press conference is never boring, thanks to Lei Jun's interesting speech.
I thought that Xiaomi's trip was to share technical details about Xiaomi cars, but Lei Jun, who first suppressed and then promoted, always brought something unexpected. The popularization of easy-to-understand new energy vehicle technology is one thing, and Mr. Lei did not hesitate to bring the pre-release of Xiaomi's first model, SU7.
Even though the new energy vehicle market is seriously involuted and Xiaomi Auto is under great pressure, Lei Jun in the speech still smiled confidently.
You can't give too many surprises, there is not much difference between the licensing of Xiaomi cars and traditional car companies, and the ** that everyone wants to see the most is naturally absent, and a press conference is inexhaustible.
Even if there is no **, the content of Xiaomi's automotive technology conference, each item is worth taking out and nagging.
In order to make it easier for us to understand the system engineering of electric vehicles, Lei Jun divided the technology of Xiaomi cars into five parts.
The core technology in the era of fuel vehicles is the engine, and when it comes to new energy vehicles, it is the electric motor. Xiaomi's two new super motors were the first to be unveiled, namely V6 and V6SBoth motors can reach a maximum speed of 21,000 rpm. The reason why it is called V6 is that Lei Jun believes that it can be comparable to the V6 engine in the era of fuel vehicles.
The 21,000 rpm motor is not uncommon today, and the high-performance motor equipped with the ZEEKR 001 FR can already be overclocked to 24,000 rpm at a maximum speed. Lei Jun was quite puzzled by being cut off, and admitted that this was the direction of the industry's involution, but he still found the answer that was far ahead.
Higher peak power and more torque are king.
Lei Jun said that Xiaomi Auto also has a more powerful V8S super motor is in the pre-research, its maximum speed reaches 27200 rpm, a single motor module can provide power comparable to V8 engine, the peak torque has come to 635 Nm, and the efficiency has reached 9811%。
This terrifying motor will land in 2025, but Xiaomi has even bigger ambitions.
Painting pie is a common phenomenon in the automotive industry, and the release of a car is divided into several steps, and there is a certain cycle from finalization to delivery. Lei Jun believes that pre-research is an important measure of technical reserves, and it has to be done. In addition to the motor comparable to V8, Xiaomi also has a super motor based on the carbon fiber laser winding process, and the laboratory test speed has exceeded 35,000 rpm, but it will take some time for mass production to land.
As a latecomer, Xiaomi Auto has spared no effort in technical reserves, improving motor technology through self-development, and the book data is ahead of its peers, which is the most intuitive performance that consumers can feel. The actual performance we do not know, the means of Xiaomi volume parameters are already well known in the field of smartphones.
At least, Xiaomi Auto has taken Tesla and Porsche from a parametric point of view.
Power battery is the cornerstone of electric vehicles, and it is also one of the core components.
Xiaomi can't develop its own battery cells, but the battery pack has the ability to develop it independently. The power battery on Xiaomi's first model is the result of two years of cooperation with the world's leading battery manufacturer. Of course, it also supports mainstream 800V high-voltage platforms with a maximum peak voltage of 871V. Lei Jun laughed and said that this should be able to call 900v.
He also took this opportunity to mock 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, which allows the battery pack to be integrated with the chassis of the car, on the one hand, to improve the strength of the vehicle structure, on the other hand, to reduce the thickness of the bottom plate, leaving space for the cockpit.
Improving the volume utilization rate of the battery and greatly reducing the number of wiring harnesses have significant advantages in the battery life and safety of Xiaomi cars. Lei Jun revealed that the battery capacity of Xiaomi's first car is up to 101kWh, and the range can reach 800 kilometers, with 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 the 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 frankly that the cost price of such a battery is at least hundreds of thousands.
Of course, the battery pack also has other results brought by Xiaomi's self-development, the battery cell inversion technology is the first in the industry, the battery cell can quickly release energy to the ground after being impacted, and the negative impact of thermal runaway can be minimized. At the same time, Xiaomi has also added 165 pieces of aerogel insulation materials to the battery pack, and with a series of safety measures, the safety factor of the Xiaomi battery pack is several times higher than the industry standard.
As a newcomer to the automotive circuit, Xiaomi's definition of the first car is advanced enoughStarting from the 800V platform, CTB integrated battery pack technology is the mainstream development direction of electric vehicles in the future. Considering the problem of discounted battery life in winter, Xiaomi has also come up with its own solution.
The high-efficiency dual-mode heat pump technology is an improvement of Xiaomi's heat pump, which can take into account the heating of the battery and the cockpit at the same time in sub-zero bad weather, so that the battery can always be kept in the best working condition, so as to alleviate the trouble of discounted battery life.
Entering the industry late has the advantage of entering the industry late, the most obvious is to avoid detours. The new car-making forces that have previously joined the ranks of car building have found the way for these latecomers, and they have reduced many of the costs and time wasted in the exploration process. Xiaomi Auto proves itself with a variety of advanced technologies, even if it is a new player, but the technical content is not less than that of its peers, and it also has a mature enough solution.
It is obviously the right choice to dispel consumers' doubts about Xiaomi cars in terms of technical strength.
Xiaomi is currently one of the few Internet companies that build its own production line to build cars, and will have its own factory for the production of battery packs in the later stage.
So Lei Jun took some time to introduce us to the breakthrough of Xiaomi Auto in production line technology.
Die-casting technology is a representative of the industrial level of car-making enterprises, Lei Jun said that the current die-casting machine in Tesla's U.S. factory has a clamping force of 9,000 tons. Xiaomi's super large die-casting equipment cluster, the clamping force is one level ahead of Tesla, reaching 9,100 tons.
9 major processes, 60 equipment, precise control of 433 process parameters, 840 square meters of floor area, and 1050 tons of total weight are the most intuitive parameters of Xiaomi's super large die-casting equipment cluster. This is more indicators that Xiaomi can take out in addition to the clamping force, and it seems to mock the peers who only roll the clamping force.
The greater clamping force means that Xiaomi is able to manufacture die-cast structural parts with higher structural strength and precision, and can also integrate more parts and components into one through one-piece die-casting in exchange for higher strengthand lower production costs. However, the repairable space after a high-speed collision is still a major problem faced by integrated die-casting, and Xiaomi cars, which are determined to redefine the future, believe they also have their own set of solutions.
After all, electric vehicles are highly dependent on integration, and the higher the integration, the more space there is for users, and more space can be reserved for high configurations.
And what is a bit of an eye for the safety of Xiaomi cars should be Xiaomi Titan alloy. Lei Jun introduced that this is Xiaomi's AI ability to find the best-performing formula from 10.16 million solutions, and call it Titan. With Xiaomi's advanced production line, it can be said that the structural safety of Xiaomi cars no longer needs to be doubted.
All this is also the result of Xiaomi's self-research with a lot of effort.
What mobile phone manufacturers are best at must be interaction and intelligence, and Xiaomi has a natural advantage in this field.
We have drawn the answer from the existing intelligent cockpit solutions on the market, they are more experienced than traditional car companies in the field of smart cars, know how to create an efficient and practical interactive system, and use their own longboard in intelligence and ecology to open up a different track from traditional car companies.
Whether it is a smart cockpit or intelligent driving, Xiaomi chooses full-stack self-research and uses intelligent algorithms to create the hardest spear for Xiaomi cars. For the field of intelligent driving, Xiaomi has launched the Zoom BEV Super Resolution Occupancy Network and the Road Large Model. The combination of the three has only one result - very good.
The zoom BEV gives the vehicle the ability to adjust the focus for different scenes, so that it can see accurately on narrow roads and see far away on high-speed roads. Lei Jun showed off at the press conference, Xiaomi car SU7 can accurately park into a very narrow mechanical parking space, and the technology is comparable to that of an old driver.
The super-resolution occupancy network and the road model are technologies that enhance the cognitive ability of the system, enabling Xiaomi Auto to more accurately judge the small bullying obstacles on the road surface, and make AI corrections to some incorrectly identified parts to enhance the vehicle's perception 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 very high level. Arming intelligence to all corners of the car, relying on software-defined chassis, and enhancing vehicle capabilities through OTA are the prominent points of domestic smart cars. What peers have, Xiaomi does better, and what peers don't have, Xiaomi can take out.
The smart cockpit is Xiaomi's home field,Lei Jun said at the press conference,Xiaomi car SU7 will be equipped with a pad-level car machine screen,The resolution has reached an astonishing 3K level, and it has achieved a leading generation in the degree of touch and hand, the degree of freedom of hand-car linkage, and the animation display.
So will the industry's first automotive-grade 120hz happen on Xiaomi cars?
Xiaomi mobile phones give the car surging OS a higher upper limit of the ability, on the one hand, it can allow the car machine 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. With the blessing of the 8295 chip, Xiaomi cars can drive more display screens, including connected tablets.
Of course, Apple users can also have a good experience.
By the way, Xiaomi has also developed a special interface standard for cars, which can allow the vehicle to be connected to an external large screen, and even a row of physical buttons. With the gradual improvement of Xiaomi cariot, it is believed that Xiaomi cars can rely on this set of interface standards to become more flexible and practical.
At this point, the first half of Xiaomi's automotive technology conference is over.
The classic image in the history of automobile manufacturing, in the end, is still a sedan, this is Lei Jun's consideration of Xiaomi's first car.
Lei Jun always likes to give us a little surprise, warm-up said only to release technology, no products, as a result, the second half of Xiaomi's automotive technology conference, is the world debut of Xiaomi's first car SU7.
Careful people may find some easter eggs, two Xiaomi Su7 that came to the scene, there is no operator in the driver's seat, but they drive on the stage by themselves, which is quite interesting for the Zhijie S7 to appear on stage, and it also played a wave of advertisements for the intelligent assisted driving of Xiaomi cars.
At the beginning of Xiaomi Su7**, the capable and avant-garde design attracted a lot of people. The lines of the Porsche Taycan are not in line with the mainstream design languageIt doesn't look good at first glance, but Lei Jun wanted a design that would stand the test of time and inspire people's desire to drive.
For this reason, the design lineup of the Xiaomi Su7 is extremely luxurious, and many of the design team are former BMW chief designers.
The semi-hidden doorknob with full practicality is less ceremonial and more lightweight to open the door. Even so, the drag coefficient of Xiaomi Su7 is controlled at 0195cd, which is the top level in the automotive 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, and it is not easy to clean it up.
Chris Bangor, one of the top 10 most famous car designers in the world, believes that the Xiaomi SU7 is not over-designed.
If this car is more than ten years old, or even decades later, its design can be regarded as a representative, and it will become a classic in the future. Just one design is enough for Xiaomi to spend a larger space to introduce.
But good-looking is only the first impression of Xiaomi Su7 , and the good-looking design is not enough to support the three-dimensional sense of the product. Lei Jun has emphasized many times that the product power of SU7 is very strong, not 9990,000 yuan, sold for 14990,000 yuan can be done.
At the scene, Lei Jun announced two versions of the SU7, but mainly the MAX version, equipped with dual motors, with a maximum output of 673 horsepower, and only 278 seconds. It has a range of 800 km and has dual Orin chips and customized LiDAR. At the same time, the SU7 also has the largest trunk volume at present, with a full 105 liters, which is enough for fishing enthusiasts to take off on the spot.
In addition, Xiaomi has taken its multi-device ecological moat to the extreme, SU7 can not only be linked with Xiaomi mobile phones, but also can establish contact with more IoT devices through the Mijia ecosystem.
The standard version may have a good **, but the configuration gap with the MAX version is too big, and I don't know if a compromise version will be launched in the future. The MAX version of the product is very powerful, and the actual ** may not be low, which will have to wait for the first half of next year, Lei Jun will answer for you again.
This is the last time I started a business in my life, and Xiaomi Auto has taken this step, and I can't go back.
It has been 1,003 days since Xiaomi officially announced that it would build a car. Lei Jun did not have too many exciting stories at the end of the press conference, nor did he have the firepower of benchmarking friends, he just said that Xiaomi would double its investment and do a good job in the automobile business. Obviously, the SU7 is a beautiful start to Xiaomi's car business, and it is also a perfect turn for Xiaomi.
Without a solid reputation and a deep automobile manufacturing heritage, it is more difficult for Internet companies to step out of their comfort zone and enter the automobile manufacturing track. The new forces that have challenged the traditional automotive industry have also experienced such challenges, and it is not difficult to understand why Xiaomi wants to pay tribute to these pioneers .
However, the Internet brand represented by Xiaomi has the color required for smart cars. Electrification, intelligence, deep integration between cars and smartphones, efficient intelligent cockpit system interaction, and advanced intelligent assisted driving systems. These have more desirable experience in Internet companies.
These characteristics are not all possessed by traditional car companies, and it is even more difficult to catch up in the short term.
The Xiaomi car technology conference is very long, in the full three hours, Lei Jun brought us a lot of dry goods about Xiaomi cars, the core of the technology conference, or to show the strength of Xiaomi cars to the outside world, to meet the expectations of potential customers. Through 15 to 20 years of hard work, it has become one of the top five car manufacturers in the world, and Xiaomi has its own self-confidence and pursuit in this automobile market where the head is gradually becoming significant.
By the way, Lei Jun also became a new energy vehicle lecturer, popularizing a wave of electric vehicle parts and technical principles. The popularization of knowledge may also be integrated into the service chain of Xiaomi Automobile.
In Lei Jun's view, the car of the future should be a good-looking, easy-to-drive, comfortable and safe mobile intelligent spaceWhat about the protagonist of the 0 era?
In the last days of 2023, Xiaomi will be remembered with the biggest step in its history. The next time the SU7 will be unveiled is a major international auto show next year. We are still looking forward to the final price of the SU7, after all, in the field of mobile phones, Xiaomi's stacking and pricing have always been very conscientious.
Lei Jun's Deram Car has arrived, so is the SU7 the dream car that surpasses Porsche and Tesla in the minds of rice fans?
