On December 28th, the 1003rd day from Xiaomi's official announcement of the car, Xiaomi Auto held its first press conference in Beijing. Throughout the press conference, Lei Jun mentioned the world's first and the best in the same class many times, especially the 28 times he mentioned Porsche, and the Taycan more than 40 times.
Lei Jun said at the beginning: "The goal of Xiaomi Auto is to build a dream car comparable to Porsche and Tesla, and the first new era." β
Yu Chengdong likes to use BBA as the background at the press conference, and the benchmark object of Xiaomi Su7 is obviously higher, which is also destined to Xiaomi Su7 will not take the cost-effective route like mobile phones. People expect Xiaomi to come up with 1999 that shook the industry like 12 years ago, but Lei Jun said: "Don't talk about 990,000, impossible, don't talk about 1490,000, we still have to respect technology. β
Lei Jun is not eloquent, his self-confidence comes from Xiaomi's technical advantages and self-research capabilities. "There is a benefit of being late, and our technical starting point is relatively high. Lei Jun said.
At the press conference, Lei Jun introduced Xiaomi's achievements in the fields of motor electronic control, integrated die-casting, and self-developed battery technology, as well as the design and ecological advantages of Xiaomi SU7. This information is enough for people to see the seriousness and devotion to Xiaomi's car manufacturing.
Five self-developed and full strength
Technology companies entering the car industry are usually relatively weak in terms of basic mechanical and electrical capabilities in the initial stage. For example, Huawei's transformation from SF5 to Wenjie M5 and M7 is based on Dongfeng Xiaokang's models, and it was not until this year that the full stack was replaced with Huawei componentsWhen entering, I chose to cooperate with Geely, using Geely's SEA architecture.
But Xiaomi chose to self-develop, and in the past 1,000 days, Xiaomi has developed its own vehicle platform, three electrics, smart cabin, smart driving and die-casting clusters.
Motor:Xiaomi has launched two types of motors, named in homage to the gasoline engine, namely the V6 and the V6S. The V6 uses a 400V architecture with a maximum power of 299 hp and a maximum torque of 400Nm, while the V6S uses an 800V architecture with 374 hp and 500Nm. The biggest highlight of the electric motor is the 21,000 rpm, which surpasses the Tesla Model S Plaid and the Porsche Taycan Turbo. Both motors will be mounted on the Xiaomi Su7, and the all-wheel drive version will use a combination of V6 + V6S, which will surpass the Porsche Taycan Turbo in acceleration performance.
Xiaomi has also launched a V8S motor, which uses AI technology to optimize the structural design and uses a high-strength silicon steel sheet with a yield strength of 960MPa, compared to 450MPa for traditional motors.
The stronger silicon steel sheet can prevent the rotor from bursting at high revolutions, giving the heat dissipation improvement brought by bi-directional oil cooling, and the parameters of the V8S have come to 27200rpm, 578 horsepower, and 635Nm. This is done without the use of carbon fiber rotor wrapping, avoiding the reduction in efficiency caused by carbon fiber wrapping. And the Xiaomi motor, which is wrapped in carbon fiber, has achieved 35,000rpm in the laboratory.
Why roll the speed?Electric vehicles do not have a gearbox, and the speed is positively correlated with the motor speed, but many motors will have a torque drop due to high temperature at high speed, resulting in a lower top speed, while the high-speed motor can provide better power reserve at high speed, which is also the reason why Huawei, Xiaomi, Tesla, and Zeekrypton are all rolling up the speed.
Battery:The Xiaomi SU7 will adopt the CTB body battery integration technology, and the battery cell is a Kirin battery cell provided by CATL, using an 800V architecture, and at the same time using dual large-face liquid cooling, side aerogel and cell inversion technology to ensure safety.
One-piece die-casting:The Xiaomi SU7 will use a one-piece die-cast rear floor, which comes from Xiaomi's customized die-casting machine, which can reach 9,100 tons, surpassing the 9,000 tons of Tesla's Cybertruck and the 6,000 tons of Model Y. The higher tonnage means that Xiaomi can integrate more structures on one component, and the rear floor of the Xiaomi Su7 has achieved 72 in one, while the durability reaches 200 kilometers, the noise is reduced by 2 decibels, the solder joints are reduced by 840, and the weight is reduced by 17%. In response to the high maintenance cost caused by large die casting, Xiaomi has designed a three-stage anti-collision structure, which can protect large die castings from damage in the event of medium and light collisions.
It is worth mentioning that, unlike other car companies purchasing external die-casting materials, Xiaomi has developed its own multi-material AI** system, conducted 10.16 million simulations** experiments, and finally screened out Xiaomi Titan Alloy that takes into account strength, toughness and stability, which also makes Xiaomi the only domestic automobile manufacturer with self-developed large die-casting materials that can be mass-produced.
Smart cabin, smart driving:Software is the strength of a technology company like Xiaomi Huawei, and after Huawei Hongmeng deeply rewrote the cockpit intelligent driving experience, Xiaomi also killed in this field.
Xiaomi SU7 will be equipped with a surging OS system, UI UE, operating logic and HarmonyOS and Meizu FlymeOS are almost the same. The biggest highlight is that the closed loop of Xiaomi's ecology has been officially completed,Mijia smart home can be directly on the car,Xiaomi tablet can become a part of car entertainment and control through a magnetic interface,Xiaomi mobile phone can flow seamlessly with the car machine and so onγ Interestingly, in other car companies trying their best to eliminate CarPlay, Xiaomi Su7 is still wireless CarPlay. Xiaomi's idea of making a car machine is very similar to that of a mobile phone, and users try to give everything they need, just like Xiaomi mobile phones still retain the function of infrared control.
In terms of intelligent driving, Xiaomi also has it, and Xiaomi Su7 will be equipped with MI Pilot intelligent driving system, which supports high-level pilot intelligent driving on high-speed and urban roads. In terms of technical solutions, MI Pilot zoom BEV, high-precision occupancy network technology and other technologies can fully keep up with the rhythm of first-line players such as Huawei and Xiaopeng in terms of solutions, Lei Jun also said: "Xiaomi will become the first echelon of intelligent driving in 2024." β
Modena Platform:Modena is a city in northern Italy, famous for being the headquarters of Ferrari and Lamborghini, hence the name Xiaomi has chosen to become a desirable car brand. The design of the Modena platform starts with 100 items "No.
1. Only. First, the most "starting point, to ensure the overall safety, efficiency of the technology leadership. Most of the technologies we have introduced above will be carried on the Modena platform and the Xiaomi Su7.
The first battle is a decisive battle
Lei Jun once stated Xiaomi's advantages in automobile manufacturing in an internal letter to employees:
1. Xiaomi Group has a strong brand power and a huge user base
2. The company has abundant cash flow resources;
3. Xiaomi Group has a deep understanding of the hardware-based Internet service business model
4. The company continues to increase investment in the automotive business and has the technical ability to apply automobiles
5. The group's strategy is "people, cars, and home ecology", Xiaomi Group has a diversified ecosystem, and unifies the software architecture of the four systems of MIUI, Vela, Mina, and car OS.
Judging from this technology conference, Xiaomi has also given full play to these advantages.
There are a lot of technical details covered in this technical conference, and this article is just a rough idea. Such a slow three-hour dry goods conference not only did not make people feel dull and lengthy, but made people constantly marvel at the depth of Xiaomi's technical reserves. Earlier, I went to experience Xiaomi Su7 is the same feeling, such a model with highlights in all aspects, it turned out to be from a company that made a car for the first time.
Lei Jun denied 99 and 14The price of 90,000 makes people more convinced that the su7 will sell for 1990 thousand. In this way, Xiaomi Su7 is a standard 532 model (that is, 5 meters long, 3 meters wheelbase, 200,000 level price). It's a segment that once dominated Modle 3 and is now packed with competitors.
At present, the 532 market has Model 3, BYD Han, Extreme Krypton 007, Xiaopeng P7, Zhijie S7, AVATR 12, Weilai ET5, Star Era ES and other powerful players, and compared with them, Xiaomi Su7 is completely comparable to or even surpasses the strength.
More importantly, Xiaomi has a strong user base, brand influence, a strong Mijia ecosystem, software capabilities and a nationwide channel network that are not weaker than Huawei's. Guojin *** Xiaomi SU7 competitiveness is highlighted, Xiaomi's own scientific and technological attributes are coupled with the characteristics of popular models, and it is expected to replicate the success of Huawei's system under the resonance of ecology and traffic, and smoothly lead Xiaomi into a new stage of development.
But it must also be admitted frankly that it is more difficult for Xiaomi to build a car than Huawei, and the difficulty is that it is difficult to be born at the wrong time.
Unlike Huawei, Wei Xiaoli, and other brands that have been making cars for four or five years, or even longer, Xiaomi has entered the market too late. Xiaomi SU7 is planned to be mass-produced and delivered in the first half of 2024, which will be the node of the industry's internal volume upgrade. Throughout 2023, the involution of the automobile industry will continue to escalate, and there will be a protracted battle in 2024. Yu Chengdong once predicted this year that there will be no more than 5 main players in China's automotive industry in the future. Li Xueyong, deputy general manager of Chery Automobile Co., Ltd., general manager of Chery Marketing Company, and general manager of Jietu Automobile, also said that there will be only 3 5 Chinese brands left in the next two years.
Therefore, Xiaomi su7The first battle is a decisive battle, not only to sell, but also to sell well, to create enough sales base for Xiaomi, so that Xiaomi can promote more products as soon as possible, this window period is extremely short, forcing Xiaomi to reduce mistakes and inefficiencies as much as possible.
However, Huawei, Weilai, and Ideal have all made difficult problems such as the ramp-up of production capacity and channel exploration and running-in, and Xiaomi will inevitably take time to make mistakes and step on pits. How to deal with these contradictions is the bigger problem facing Lei Jun. However, some industry insiders said that smart electric vehicles are going through the transition stage from the early stage of smartphone development to the second half, and the market concentration is still relatively low. From the perspective of the structure of the development history of the mobile phone market, the first mover may not come to the end, and the late mover still has the opportunity to catch up.
Lei Jun said with a smile at the press conference: "We are not afraid of the involution of the industry, Xiaomi has been 'rolled' since childhood." As the godfather of entrepreneurship and investment, Lei Jun will obviously not allow failure for the last business in his life. Whether Xiaomi Auto can replicate Huawei's success and whether it can withstand involution, the story has just begun.
