Xiaomi, as a manufacturer with its own traffic in the digital circle, is suitable for netizens to stare at every word and deed, especially after announcing the battle for Xiaomi cars. Before the start of Xiaomi's automotive technology conference, Lei Jun set the benchmark models in advance: Porsche Taycan Trubo and Tesla Model S. One is the representative of the car as a travel vehicle for a hundred years, and the other is the representative of the middle end of mobile computing
For car building, Lei Jun has a very clear understanding and attitude, if you just want to save a car, it only takes 2 years of reverse engineering to do it, the required R & D personnel are not more than 100 people, and the R & D funds of 1 billion are enough. It's a pity that Lei Jun wants to make a dream car for users, and the car-making team has a total of more than 3,400 engineers, and has invested 10 billion yuan to start from the bottom core of positive research and development, and seriously make a good car.
At the Xiaomi automotive technology conference, Lei Jun showed you the five core technologies of Xiaomi SU7: electric drive, battery, large die-casting, intelligent driving, and intelligent cockpit.
The Xiaomi SU7 is equipped with two motors, the Xiaomi Super V6 and the V6S, both with a speed of 21,000 rpm, ahead of Tesla and Porsche. The third V8S, which is completely independently developed and produced, achieves 27,200 rpm and a motor power density of 1014kw kg, the world's top.
PS, the motor is already in mass production and will be installed in 2025.
Xiaomi's self-developed CTB battery integration technology. The self-developed new super 800V silicon carbide high-voltage platform has made a real 800V high, up to 871V. The self-developed battery pack has 17 layers of high-voltage insulation protection, 14 layers of hard-core physical protection, and is filled with 165 pieces of aerospace-grade aerogel thermal insulation material. 132 patents have been applied. 65 have been authorized.
In terms of materials, it cooperates with the National Key Laboratory of Materials. Self-developed Titan alloy;In terms of manufacturing, we have developed a self-developed equipment cluster system, which can realize a 72-in-one integrated die-casting rear floor. Completed the full set of large die-casting process and standard self-development.
It adopts the latest generation of underlying algorithms: BEV+Transformer + Occupancy Network, and fully integrates large model technology. Using the three major technologies of "zoom BEV technology", "super resolution occupancy network technology" and "road large model technology", Xiaomi Su7 can be seen, seen accurately, and understandably.
Based on Xiaomi's surging OS operating system, using Snapdragon 8295 cockpit chip, AI computing power up to 30TOPS, 1The car can be fully started in 49 seconds. The car is equipped with 161-inch 3K ultra-clear central control screen, 56-inch large HUD head-up display, 71-inch flip instrument panel.
Xiaomi cars surpass Porsche, there are two sets of very hard data:
100km h acceleration, Xiaomi Su7 278s, Porsche Taycan Trubo 293s
0km h braking distance, Xiaomi Su7 33M, Porsche Taycan Trubo 34M
Domestic cars want to surpass overseas luxury brands, it is difficult to say, but it is not impossible to achieve, Xiaomi Su7 only uses super motor V6S to achieve a slight lead, the follow-up use of V8S, will it be a large lead?
