Recently, the Xiaomi Automotive Technology Conference was held at the National Convention Center, officially disclosing the progress and breakthroughs of the five core technologies of Xiaomi Automobile, and ushering in the debut of the platform's first product, Xiaomi Su7.
Then the five core technologies are introduced
Motors: At the press conference, Xiaomi released three motors: V7, V7S, and V8S, with a speed of 21000-27200rpm, all of which have been mass-produced. Among them, the HyperEngine V8S super motor with a speed of up to 27,200 rpm has a power density of 10It has a high power output of 425kW and a peak torque of 635Nm at 14 kW kg.
The HyperEngine V6 V6S super motor ranks first in the industry with a speed of 21,000 rpm. Among them, the HyperEngine V6 super motor has a maximum power of 299 PS and a maximum torque of 400 Nm, while the HyperEngine V6S super motor has a maximum power of 374 PS and a maximum torque of 500 Nm.
Battery: In terms of battery technology, Xiaomi's 800V silicon carbide high-voltage platform, CTB integrated battery technology, etc., support up to 150kWh of power, and CLTC has a range of more than 1200km. In addition, it can install 132 kWh of electricity under the mature system and have a range of 1,000 kilometers.
Among them, the CTB integrated battery of Xiaomi car adopts the floor cover double.
1. The design of inverted cells, multi-functional elastic interlayer and minimalist wiring harness. At the same time, Xiaomi has also introduced a multi-functional elastic interlayer, which has been improved by 65% integration efficiency.
Super large die casting technology:
Xiaomi relies on its self-developed 9100T super large die-casting technology - Xiaomi Hypercasting, in which the visual large model quality judgment system can complete the inspection within 2 seconds, with 10 times the high efficiency of manual labor and 5 times the high accuracy of the elite. As a result, the rear floor of Xiaomi cars has achieved 72 parts in one, 840 solder joints have been reduced, the overall weight has been reduced by 17%, and the production man-hours have been greatly reduced by 45%. In terms of material research and development, the self-developed high-strength, high-toughness heat-free and environmentally friendly die-casting material Titan Alloy, it is worth mentioning that Titan Alloy contains 30% recycled aluminum.
In addition, Xiaomi Auto adopts a three-stage serviceable design: integrated die-cast rear floor + medium and high speed collapse zone + low speed collapse area. In low- and medium-speed collisions, there is no need to replace large die castings;In a high-speed collision, this design can meet the 90km h rear collision standard.
Autonomous driving technology:
Xiaomi's intelligent driving consists of three key technologies, adaptive zoom BEV technology, road large model, and super-resolution occupancy network technology. Among them, the adaptive zoom BEV technology can adaptively call different perception algorithms according to different scenarios. The perception grid can be as small as 005m, up to 02m, the recognition range extends from 5cm to 250m, the parking scene is more accurate, the urban scene is wider, and the high-speed scene is farther.
In terms of hardware, the system is equipped with top-of-the-line configurations, including 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 version of the model).
Intelligent cockpit: The intelligent cockpit adopts a "human-centric" interactive architecture and is equipped with 161-inch 3K ultra-clear central control screen, 56-inch large HUD head-up display and 71-inch flip instrument screen. It supports the visual unified design language of Xiaomi Surging OS, and is equipped with a five-seat five-tone interaction function to support stable and collaborative wake-up of multiple devices. At the same time, the starting speed of the car machine is 149 seconds. In addition, the intelligent cockpit also has super powerful ecological application expansion capabilities, including Pad APP sharing, mobile APP sharing, and ecological hardware sharing.
In the ecological screen of Renchejia, you can control the car with one click. At the same time, the Xiaomi Pad can also be hooked up in the car. At present, the Xiaomi smart cockpit has supported 1000+ Mi home devices, automatic discovery, password-free access, and can set up automation scenarios. It is worth mentioning that the built-in Cariot docking station supports the access of a series of devices, and also supports wireless CarPlay.
What exactly is the Xiaomi Su7
Having said all that, what exactly is the Xiaomi Su7?Just today, Xiaomi Auto officially released the first batch of real shots of its first pure electric model, the Xiaomi Su7**.
In terms of appearance, the official name of the color scheme is Gulf Blue, and the overall shape is very similar to the Porsche Taycan, with a coupe design, the front part of the car is relatively low, the front face is closed, and it is equipped with a matrix headlight group. Huge polygonal headlight clusters with rounded corners emit a unique glow from the inside with rice-shaped elements. The lower bumper has a three-section design with large deflectors on both sides, and black trim is added around it to improve aerodynamics.
The sides of the car have coupe-like lines, yellow brake calipers and open door handles. At the rear, there is an electric rear spoiler that can be lifted and lowered and taillights are designed through. And there is a brand logo of "xiaomi", and the tail label is "Beijing Xiaomi".
In terms of body size, the length, width and height of the new car are 4997 1963 1440mm, and the wheelbase is 3000mm, positioning it as a medium and large pure electric car.
In terms of power, the new car is available in single-motor and dual-motor versions, with a peak power of 220kW for a single motor and 220kW and 275kW for dual motors, respectively. In terms of range, there are two battery versions with a capacity of 101kWh and 736kwh。Among them, depending on the model, the CLTC range corresponding to 101kWh is 800km and 750km respectively73.The CLTC range corresponding to the 6kWh is 668 km and 628 km, respectively.
Although the new energy vehicle market is a growing emerging market, the competition in the entire new energy market is very fierce due to the addition of too many new power brands. Up to now, there has been a wave of brands that have gained a firm foothold, and a wave of brands that have left the scene. Looking at Xiaomi SU7, it is clear that SU7 will compete with Tesla Model 3, Xpeng P7, Zhijie S7, BYD Han and other models. Potential opponents will also include Feifan F7, Alpha S, VOYAH Chasing Light, Zhiji L5, Nezha S, Leap C01 and so on.
Let's look at the body first,It is not difficult to see,XiaomiSu7The body length and wheelbase are more powerful,The wheelbase is the same as FeifanF7,The body width is the same as that of ZhijieS7,It can be seen that XiaomiSu7In terms of body, it is already the best in the class。 The height is lower than the rest of the models, which is why it looks low, which also has an impact on the drag coefficient. Of course, the body is large, and the interior space will not be bad.
Let's take a look at the power, whether it is a dual-motor version or a single-motor version, Xiaomi Su7 beats its opponents in terms of power performance, and other details are expected to be quite amazing after the announcement of the 000 km acceleration results. Moreover, there are a variety of options in terms of range, and it can reach a maximum of 800 kilometers, which is also outstanding in its class. Even the veteran BYD Han is willing to bow down. In addition, the Xiaomi Su7 will be available in two types: a 400V voltage platform and an 800V high-voltage platform.
2024 is already the third year of the rapid development of new energy vehicles, from less than 3 million new energy models in 2021 to 688 in 2022Sales of 70,000 units have skyrocketed, and by 2023, sales in a single month alone will exceed one million units, and the annual sales volume is expected to reach about 9.4 million units. The sales of new energy vehicles have skyrocketed, the growth rate will gradually slow down, the market will gradually stabilize, forming an inherent pattern, and the share of emerging products is not much, if you want to quickly gain a firm foothold, you must come up with your own strength, and ** is the most basic factor that determines the strength. So what do you think of the Xiaomi Su7 pricing?
