1003 days after the announcement, Xiaomi entered an important stage of development.
Xiaomi held an automotive technology conference on December 28, in addition to announcing Xiaomi's first model, the Su7, it also released its own first model, the Su7. The grand blueprint of Xiaomi's car manufacturing is in full swing, and its ** is still a mystery.
At the more than three-hour press conference, Lei Jun, who had just turned 54, looked excited. "Xiaomi's goal is to keep pace with Porsche and Tesla, and strive to become one of the world's top five car companies within 15 to 20 years. ”
At the beginning of the press conference, Lei Jun introduced Xiaomi's five core technologies in detail: electric drive, battery, large mold, intelligent cockpit, and intelligent driving.
As the core technology of electric vehicles, the performance of electric motor will directly affect the performance of the whole vehicle. Under the same torque conditions, the higher the rotor speed, the greater the power output of the motor, and the better the dynamics of the vehicle.
After Xiaomi announced the production of cars, the first project was the production of super electric motors, and now the V6 and V6 motors produced by Xiaomi with a speed of 21,000 rpm will be installed on the first model of the Xiaomi SU7. The third V8S, with a power of up to 27,200 rpm, is expected to be put into service in 2025, plus a pre-developed engine with a maximum speed of 35,000 rpm.
In an all-electric vehicle, the battery is the most expensive component. Xiaomi has partnered with CATL to develop Xiaomi's 800-volt high-voltage battery pack in two years. Xiaomi has registered 132 patents on batteries, 65 of which have been licensed.
In terms of low-temperature battery life, Xiaomi has released a new cooling system, which is claimed to allow cars in the same level to heat up faster, and can also allow it to maintain a higher temperature at low temperatures, maintain a higher temperature at lower temperatures, and charge faster.
Xiaomi has chosen its own factory and its own R&D. The die-casting island covers an area of 840 square meters, the size of two basketball courts, and weighs 1050 tons, and the molds and equipment are independently developed.
Xiaomi plans to enter the front line next year to achieve full coverage of major cities in China. The investment in the first phase is 4.7 billion, with more than 1,000 team members and more than 200 test vehicles already on the way.
Xiaomi's intelligent driving system uses the latest generation of BEV+ Transformer + to occupy the new generation of computing methods of the network, and fully integrates the technology of big data mode. In terms of intelligent driving, Xiaomi has come up with technologies such as "zoom BEV technology", "super-resolution occupancy network technology", and "road big data modeling technology" to improve the accuracy and effectiveness of vehicle recognition.
On the hardware platform of intelligent driving, Xiaomi cars are equipped with two chips with high computing power of NVIDIA Drive Orin (NVIDIA Drive Orin), with a total computing power of up to 508 TOPS, at this point, it is an intelligent driving system with independent intellectual property rights. In addition to this, there is one lidar, eleven high-definition cameras, three millimeter-wave radars, and twelve ultrasonic radars.
In terms of software, Xiaomi Auto will install the "surging operating system", which allows users to interact freely on different platforms, and can provide users with 149 seconds of fast start-up service.
Xiaomi Auto provides the best service for Apple, it not only supports the wireless CarPlay function of the whole car, but also on AirPlay*** It also supports the rear seat expansion function of the iPad, and can also control the air conditioning, listening**, and seats. "I think that using Xiaomi cars will give us a good experience. ”
Xiaomi's first model, the Xiaomi Su7, is positioned as a "C-class luxury eco-friendly car", targeting the "elite of the times", pursuing cutting-edge technology, loving life, and pursuing excellent design and experience.
Lei Jun revealed that the shape design of Xiaomi Su7 was pushed down by him three times, which made the entire design team collapse. At first, their idea was to be different and blow up the streets, but after a survey of consumers, they found that it would take at least seven or eight years for the car to be satisfied.
Therefore, Lei Jun set this design goal in a place that can stand the test of time.
The Xiaomi Su7 is available in three colors: Ocean Blue, Ya Gray and Olive Green, with a length of 4997 mm, a wheelbase of 3000 mm, a width of 1963 mm, a height of 1440 mm, a trunk of 517 L, and a front trunk of 105 L.
The cockpit of the Xiaomi SU7 is a kind of enveloping cockpit, and the entire body has 535 square meters of glass, three-spoke D-shaped steering wheel and physical buttons. There are three colors inside, Galaxy Gray, Obsidian Black, and Dusk Red.
Xiaomi SU7's drop-shaped headlights, ring taillights, 175-degree corrugated curved surface, and semi-hidden door handles are all family styles that Lei Jun wants, which have been passed down from generation to generation.
The design of the Xiaomi car was led by Li Tianyuan, BMW's first Chinese designer, and its representative work is the BMW ix.
The Xiaomi Su7 is equipped with a 101 kWh CATL lithium battery, which supports 800 V fast charging, which can reach 220 kilometers in 5 minutes, and CLTC can reach 800 kilometers.
In terms of performance, Lei Jun described the Xiaomi Su7 as comparable to a million-level sports car. The Xiaomi Su7 is equipped with two units with a maximum horsepower of 673 PS and a maximum torque of 838 NM, it's a very good phone. Zero Hundred Acceleration 2In 78 seconds, it has a top speed of 265 km/h, surpassing the 260 km/h Porsche Taycan turbo.
Speaking of **, Lei Jun said: "Don't say 90,000, that's impossible, and as long as it's such a performance and such a configuration, the minimum is 400,000." Forget about 149,000, technology should be respected. ”
Still, Xiaomi's SU7 sedan will be a few months away from its official launch. Lei Jun said that in order to ensure that nothing goes wrong, a lot of tests must be carried out.
