After watching the 3-hour Xiaomi car technology conference, for netizens who are looking forward to Xiaomi cars**, there is only one sentence that may be useful, that is: those who say 14Don't talk about the 90,000 ones.
As a ten-year rice fan, I watched the entire Xiaomi press conference the whole way. The whole press conference, in addition to the Xiaomi Su7 appeared most frequently, the second highest is Porsche Taycan, when it comes to the torsional rigidity of the vehicle, there are Bugatti Veyron, Raptor F150, Range Rover words.
If you don't look closely, you think it's a ...... than running a score
I have to say that after watching Lei Jun's press conference, I feel like I am 16990,000, which may no longer be suitable for Xiaomi cars. I feel that Xiaomi cars are going to sell 300,000+, even the entry version cannot be less than 200,000, Xiaomi cars did not announce the price this time, obviously, if the price is too high at this time, wouldn't it help the just-listed Extreme Krypton 007, Nvidia chip, Qualcomm Snapdragon 8259, this is the same configuration as Xiaomi.
I am not disappointed with the product power of Xiaomi Auto, but I am bound to be disappointed with **. Hopefully, the Xiaomi car will not become a car: a car that rich people don't want to buy, and they can't afford to buy it. Let's talk about some other information, there are five keywords.
1003 days.
The opening Lei Jun shows that 1003 days have passed since Xiaomi announced its car manufacturing to the current automotive technology conference. At the moment when the car-making technology is relatively mature, is it a bit slow? Lei Jun also asked himself, but he said that it is easy to build a car, but it is difficult to build a good car. But Xiaomi has been in awe of making cars from the beginning, and will unswervingly build a dream car comparable to Porsche and Tesla. And determined to become a well-known car company in the world in 15-20 years, and strive for the development of global automobiles.
It can be seen that Xiaomi's ambitions are not small, and the slogan is not small. In order to show that he is doing practical things, not just doing PPT to make cars, Lei Jun showed the achievements of Xiaomi Auto from 5 aspects, which have 5 keywords.
The first key word is speed + super motor
At the beginning, Lei Jun explained that the motor is the core of car manufacturing and determines the performance of the vehicle. The speed is also the most serious area of involution of mainstream car companies, and the current level of BBA is maintained at 160,000 rpm, while Tesla's million-level product speed is up to 20,000 rpm, Xiaomi decided to make a super motor and make the fastest speed from the day it decided to build a car. A team of experts of more than 100+ people has brought two motors V6 and V6S, and the book data shows that the V6 engine is 299PS, 220kW, and 400 Nm, which is comparable to the level of a six-cylinder fuel engine. The V6S has a maximum horsepower of 374PS, 275kW, and a peak torque of 500Nm, which is comparable to the data performance of the large six-cylinder of a fuel vehicle, and the maximum speed can reach 210 thousand.
Sadly, a few days ago, Huawei launched a 22000 rpm motor, stealing Xiaomi's home. Xiaomi is no longer hiding, and it has directly enlarged its moves, unveiling the V8S, with a maximum motor horsepower of 578ps, 425kW, and a peak torque of 635Nm. The speed directly obtained 27200rpm, from the data point of view, refreshed the ceiling of the global motor field.
In terms of technical overcoming, Xiaomi has put a lot of effort into improving the strength of the rotor by redesigning the stator and rotor and self-developed SiC electronic control system, as well as two-way main body oil cooling and other technologies, and achieving laboratory data over 350,000 rpm!
The short summary is 210,000 rpm has been mass-produced, 270,000 rpm is expected to be on the bus in 2025, 350,000 transfers are currently in the laboratory achievement stage.
The second key word isCATL + CTB
Battery is the cornerstone of a pure electric vehicle, which can affect the space, power and safety of a car. In this regard, Xiaomi chose to cooperate with CATL in depth, and spent two years attaching importance to R&D and self-built factories to ensure battery performance and quality from the source, bringing an 871V silicon carbide platform and CTB integrated technology, accompanied by ASIL-D strong thermal management, to improve overall safety and battery life.
132 patents were applied for, and 65 were approved. In terms of safety, through CTB integration technology (everyone is more familiar), 165 pieces of aerogel insulation material and 14 layers of chassis protection, it is not afraid of chassis collision. Regarding the pain points of low-temperature battery life, Xiaomi has set a small goal of being the king of winter tram battery life from the perspective of northern car manufacturers. The core technology of electric vehicles depends on the battery, and the focus of the battery is thermal management. At present, the car market mainly uses heat pump technology, Xiaomi uses the ASIL-D system, adopts one heat multi-purpose, three heat source step-by-step heating technology, etc., and has passed the test of Mohe, vowing to solve the pain points of winter cars and increase low-temperature battery life.
The third keywordLarge die casting + titan alloy
Tesla opened the era of large die casting, and the Shanghai factory has a large die casting of 6,000 tons, which was pioneered by Tesla and has become an industry-wide trend. Xiaomi is determined to build its own factory, with a clamping force of 9100T, which is ahead of the 9000T data of Tesla's US factory. The self-developed equipment cluster system and the only factory with self-developed large die-casting materials that can be mass-produced have brought Titan alloy, with 10.16 million formulas, 1550 tests, and a 30% cycle rate, and Xiaomi SU7 is equipped with this alloy. And in the 72-in-1 integrated die-cast rear floor, the three-section rear floor can reduce weight and improve performance, while also bringing a higher service life.
The fourth keyword——Autonomous driving
This is also the area where technology companies enter the car-making industry that attracts the most attention from consumers.
The field of intelligence is also flying, and Xiaomi's confidence comes from three points.
1 is investment, more than 1,000 people, more than 200 vehicles, more than 10 million kilometers, and 4.7 billion investment gives it confidence.
2 is AI technology, Xiaomi has been in AI since 2016, with an investment of more than 10 billion and a team of more than 3000.
3Although Xiaomi started late, the iteration in the field of intelligent driving is fast, which means that the starting point is high, and the application is the latest technology.
Here, Xiaomi emphasizes the perception technology in the field of intelligent driving, Xiaomi strengthens the perception system, and realizes three self-developments, zoom BEV + super resolution occupation network + road model. 508topsHigh computing power chip, a lidar (a high-definition camera installed on the roof, 12 ultrasonic radars, etc.), in the face of actual car scenarios such as parking in extreme mechanical storage locations where old drivers are helpless, Xiaomi self-driving system can easily handle it.
Here, Xiaomi Auto has set a new small goal to become the first echelon in the field of intelligent driving in 2024.
The fifth keyword——Intelligent cockpit + surging OS
Five-screen linkage
The central control screen Xiaomi brought16.1 inch of 3K resolution, ultra-narrow bezel, essentially chose an oversized flatbed on the car. This is Xiaomi's professional, with a ratio of 16 to 10, which is more convenient to operate and has the best application compatibility. On the basis of the largest possible size, it does not affect the operating space. Extra-large 56-inch head-up display, rotatable instrument screen, full of ceremony, the back can hang a new version of Xiaomi pad, the rear row can be directly connected to the vehicle operation network, easy to operate, just like the original.
Surging os get on the bus
The deploymentSnapdragon 8295 chip, underlying reconstruction, cross-terminal intelligent connection, active collaboration, intelligent writing, people, cars, and homes are officially closed in this closed loop. The in-car experience is very powerfulThe first pointThe same interactive experience as a mobile phone and tablet, you can easily get started without learning. For Xiaomi users, it is exactly the same as the mobile phone, and there is no transition stage. The second point is fast, extremely fast start 149s, get on the bus and stay in place. The app starts quickly and is easy to operate. It only takes three minutes to upgrade the intelligent OTA cockpit system and 30 minutes to upgrade the whole vehicle.
Application Ecosystem
The mobile phone application is pinned to the car, and it becomes a native application in seconds. Mobile phone and car machine interconnection, split screen display, navigation flow, mapping, information full screen display, conference flow, strong ecology, mainstream vehicle applications, tablet ecology seamless on the car, more than 5,000 kinds of applications, one by one screening, gradually on the car.
Extremely large hardware ecosystem
Mijia equipment, the same account password-free and non-inductive boarding of the car, automatic connection to the car wifi, exclusive carlot ecology, pin points and magnetic suction can be expanded around the screen, and peripheral ecological devices can be installed by themselves to release personality. The storage space in the center console also has standard interfaces, smart aromatherapy machines, which can also be replaced with other ecological equipment, and the seat backs also have hardware expansion, tablets and small tables, hangers, etc. Carlot is fully open to third parties, supports wireless CarPlay, and can control the car on the iPad, which is indeed very friendly. It can also bring a richer ecosystem and a more convenient car experience.
The frequency of self-research and mention of this press conference is very high, and it can also be seen that Xiaomi Auto is not satisfied with building a car or several popular models, it is here for the first echelon in the world. Self-developed Modena platform architecture technology, the arrival of surging OS, more user-friendly to Xiaomi, ten times the investment is just to make a good car, Xiaomi car is to achieve a technological leap in science and technology and ecology, to achieve the help of science and technology, enrich the blessing of the ecosystem, and bring the integration of people and vehicles.
Regarding the Xiaomi Su7, the conference concluded with an introduction to its positioning, as well as its design team, to make a car that can stand the test of time and be a futuristic car. Xiaomi SU7 is positioned as a C-class high-performance sedan, and it will be on the market in a few months, and the size is the benchmark BMW 5 series, which is a sedan blessed by ecological * technology, so from this point of view, **will not be the same as the market **, benchmarking BYD Han or seal,
