As soon as the news of Xiaomi's car conference was confirmed, it quickly attracted great attention from the automotive and technology circles. On December 28th, Xiaomi's automotive technology was officially released, and Lei Jun was high-spirited and commanding, revealing the demeanor of a Confucian general. 
It should be said that Xiaomi Auto has put a lot of thought into this press conference - paying tribute to a circle of friends, and setting the tone in advance "only send technology, not products", whether it is attitude or content, it has done a good job. It is quite written that everyone washes their hair and takes a shower before the blind date, just to leave a good impression on each other. The Xiaomi press conference was sprinkled for more than three hours, and Lei Jun talked a lot on the spot, listing various technologies and parameters, and flying with feelings and dreams. Objectively speaking, judging from the large information density and high specifications of the press conference, this Xiaomi automotive technology conference is a rare conference in recent years. 
In the era of information, social platforms are filled with various new car reports and-for-tat confrontations with industry bigwigs every day, and everyone can receive massive automotive news all the time. Maybe it's because everyone has information fatigue because of massive information, or maybe it's because of Lei Jun's huge prestige, Xiaomi Auto's technology conference has gained huge attention, in a sense, this is the first step to success. Attention is only one aspect, the next is a real hard battle, Lei Jun also showed a 40-meter knife at the press conference, and slashed to the already vigorous Chinese new energy vehicle market. A big drama is about to unfold. It is not easy to build a car, Lei Jun said: "I felt that it was not easy to make a car before I did it, and after working for three years, I felt that building a car was special and difficult." According to Lei Jun, he hopes to build a dream car comparable to Porsche and Tesla, and create a beautiful, easy-to-use, comfortable and safe mobile intelligent space. 
But it's not easy to build a good car. When Lei Jun officially announced the construction of the car in 2021, he said that he would press all the accumulated achievements and reputation in his life to fight for Xiaomi Auto. In a sense, this is also a continuation of the spirit of "born for fever" back then. Lei Jun introduced the "how to fever" Xiaomi car from four major aspects: motor, battery, large die-casting technology and intelligent experience. Super MotorAccording to official news, Xiaomi has developed three super motors, V8S and V6S, which are comparable to the performance of the big V8 and V6 powertrains in the fuel era to refresh the industry ceiling. 
The V8S motor has a maximum speed of 27,200 rpm, a maximum horsepower of 578 PS, a peak power of 425 kW, and a peak torque of 635 Nm, with a maximum efficiency of 9811% with a power density of 1014kw kg, mass production is expected in 2025;The V6S and V6 motors reach a maximum speed of 21,000 rpm, the V6 super motor has a maximum power of 299 PS and a maximum torque of 400 Nm, while the V6S super motor has a maximum power of 374 ps and a maximum torque of 500 Nm. The first mass-produced model, the SU7, is already equipped with the Xiaomi V6 V6S motor, which was jointly developed with UMC and Inovance. Correspondingly, Tesla's Model S Plaid 20,000rpm, which costs more than one million, has a motor speed of 20,000 rpm. In addition, Xiaomi's self-developed super motor uses a carbon fiber laser winding process, and the laboratory pre-research has achieved 35000rpm, and there is still a period of time before mass production. In the field of motor and electronic control, Xiaomi has applied for 155 patents and has authorized 60 patents. Super Battery Xiaomi Auto released an 800V carbonized high-voltage platform, which is understood to have a maximum voltage of 871V, which is a veritable 800V high-voltage platform. At the same time, it has also developed CTB integrated battery technology, with a battery capacity of up to 150 degrees and a theoretical CLTC range of up to 1200km+.
1. A series of innovative designs such as inverted cells, multi-functional elastic interlayer and minimalist wiring harness design, 128 patents in the field of batteries (65 of which have been authorized) comprehensively improve the integrated efficiency, safety and heat dissipation performance of batteries. This results in an integration efficiency of 778% (the highest in the world), an overall increase of 244%。
In addition, Xiaomi has built its own battery pack factory to ensure battery performance from the source. 
This is also Lei Jun said that Xiaomi Auto wants to become the "king of winter tram endurance". Large die-casting Xiaomi uses 9100T super large die-casting technology (much larger than the 6000 tons of Tesla's Shanghai factory), which can realize the integration of 72 parts of the rear floor, reduce 840 solder joints, reduce the overall weight by 17%, and greatly reduce the production man-hours by 45%. 
Xiaomi has also become the only domestic automobile manufacturer that independently develops both a large die-casting equipment cluster and die-casting materials. In addition, after Xiaomi customized the die-casting machine, it developed a full set of assembly lines for the die-casting island, with a total of 60 devices and 433 process parameters. Xiaomi has also developed its own titan alloy in material research and development, which not only has excellent strength, toughness and stability, but also contains 30% recycled aluminum, which reduces carbon emissions by 352 per part53kg, which has made its due contribution to environmental protection. In terms of intelligent driving hardware, Xiaomi cars are equipped with two NVIDIA Orin high-computing power chips, with a comprehensive computing power of up to 508TOPS. The perception hardware includes 1 lidar, 11 high-definition cameras, 3 millimeter-wave radars, and 12 ultrasonic radars (MAX model). 
In terms of software, Xiaomi Auto has achieved breakthroughs in three aspects: adaptive zoom BEV technology, road large model and super-resolution occupancy network technology. Among them, the adaptive zoom BEV technology is the first in the industry, which can zoom like the human eye and can adaptively call different perception algorithms according to different scenes. The total investment in the first phase of Xiaomi's intelligent driving is 3.3 billion yuan, which has been increased to 4.7 billion yuan at present, and the short-term goal is to enter the first camp of the industry in 2024. Lei Jun said that although Xiaomi started late, "there are benefits of being late". Because the latest generation of technology is used. All in all, Xiaomi Auto has fully demonstrated its strength, proving that its 40-meter broadsword is more than just an ornament. Reenactment of the good drama of the year Lei Jun entered the smartphone market more than ten years ago, and the slogan of "born for fever" back then, I believe that many people have become loyal fans of Xiaomi because of this sentence, and have also witnessed Xiaomi grow into an industry giant. In the minds of many people, Xiaomi mobile phones have achieved the ultimate in cost performance by virtue of 1999 yuan of ** that year. Now, Xiaomi has entered the automotive field, and everyone also hopes that Xiaomi Auto will repeat its subversive feat in the mobile phone industry. 
In addition, Xiaomi's first model, SU7, also stands out in terms of exterior design. In terms of positioning, Xiaomi SU7 is a C-class high-performance ecological technology car, with a length of 4997mm, a width of 1963mm, a height of 1440mm, a wheelbase of 3000mm, and the lowest drag coefficient CD 0 for a car in the world195。Space performance, 1012mm front vertical seating space, 105mm rear knee room;The 517-liter trunk is the largest 105-liter trunk for a pure electric vehicle in China.
Xiaomi Su7's Zero Hundred Acceleration 278 seconds, 100 zero brakes 333 meters, the top speed can reach 265km h. In addition, Xiaomi Auto also has one of the biggest killer features, that is, Xiaomi Surging OS will create a whole ecology of people, cars and homes, with the launch of Xiaomi Automobile, this ecology will complete the closed loop. Xiaomi cars are equipped with Qualcomm Snapdragon 8295 chips, based on surging OS technology, mainly composed of 161. It is composed of a central control ecological screen, a flip instrument screen, a 56 HUD, and a rear expansion screen, which can realize the linkage of five screens.
Lei Jun said that he has created an exclusive cariot ecology for Xiaomi cars, and the cariot ecology is now fully open to third parties. Apple users also have a good experience driving a Xiaomi car, Xiaomi car supports wireless carplay, also supports airplay, and even supports ipad in the car, which can control the car's air conditioning, ** and seats. Regarding the concept of ecology, other new energy car brands on the market are also mentioning, but their statements are different. Objectively speaking, other brands are more in the air, which sounds wonderful, but in reality there is still a lot of work to be done.
Xiaomi's "people, cars, and home ecology" is different, it has been deeply cultivated for many years, not only has a deep foundation, but also this ecology is very large, including more than 600 million devices, more than 200 categories. In a sense, for Xiaomi, the car is only the last link to build the entire ecosystem, and for other brands, the car is their only one. So as far as "ecology" is concerned, Xiaomi cars are a matter of course. Regrettably, the ** of the Xiaomi Su7 has still not been announced. However, Lei Jun said when introducing the battery, "Don't 9."90,000, don't 1490,000, 10 tens of thousands of battery packs, what do you want?"Judging from Xiaomi's consistent practice, even if Xiaomi cars are more expensive, they are still the king of cost performance among competing products at the same price. I don't know who is for and who is against when this sentence is said?The people commented on the car Lei Jun previously said: Standing on the tuyere, pigs can fly to the sky. Looking back at the development of Xiaomi mobile phones, Xiaomi mobile phones did stand on the cusp of the outbreak of smartphones at that time. However, we must also see that Xiaomi mobile phones have also achieved the ultimate cost performance and extreme fever, which has achieved future achievements. What I want to say is that opportunities are important, and so is effort. Nowadays, Xiaomi cars are also standing on the tuyere, and they have also achieved the ultimate in the competition in the same level in technology research and development and product design. And Xiaomi cars also have an advantage that they didn't have back then, that is, a super ecology that makes people feel infinitely reverie. Back then, it was overcoming thorns and thorns, but now it is riding the wind and waves. Xiaomi cars are worth looking forward to!List of high-quality authors
