After three years of preparation, Xiaomi's first car has finally been officially unveiled.
On December 28, 2023, three days before the new year, Lei Jun, founder, chairman and CEO of Xiaomi Technology, took to the stage to ** Xiaomi's first car, the Su7 (pronounced Su7), which has been highly anticipated and spoilers.
The much-talked-about product ** has not been announced, and even when it is mentioned in the few mentions**, Lei Jun has to emphasize 990,000 impossible, 1490,000 doesn't have to think about it.
But the three-hour speech still caught the attention of everyone present. Lei Jun gave the positioning of Xiaomi's first car: comparable to Porsche and Tesla's Dream Car, and used 5 dimensions of R&D stories and various functions of the product to illustrate the story of 1003 days of car building.
At the end of 2023, such a narrative method seems to be somewhat incompatible with the involution environment of domestic smart electric vehicles. But such a leap story is what today's Xiaomi car needs: cost performance is no longer the main direction of this company, and continuous exploration on the road to high-end is the goal of the future.
Lei Jun said: In 1,003 days, it is easy to save a car, but it is not easy to develop it forward. At the press conference, he introduced the R&D story of Xiaomi cars from five dimensions: battery, electric drive, large die-casting, intelligent driving, and intelligent cockpit.
It is necessary to walk with the elite of the times. This was written on the PPT of the Xiaomi Su7 launch event.
As a technology company, Xiaomi's investment in automotive mechanization, electrification, manufacturing and other fields is somewhat unexpected.
In the field of electric drive, Xiaomi has spent more than two years developing its own HyperEngine V6 V6S super motor, which ranks first in the industry with a speed of 21,000 rpm, surpassing Tesla Model S Plaid. Meanwhile, another HyperEngine V8S super motor with up to 27,200rpm is expected to hit the car in 2025.
It is worth mentioning that in order to break through the physical performance of the rotor under high-speed operation, Xiaomi has also established a technical joint laboratory with Shougang to solve the problem of motor speed by using joint research and development in the field of materials.
In the field of batteries, Xiaomi has developed the world's first inverted battery CTB integrated battery (that is, the battery and the vehicle floor are integrated) battery. The maximum capacity of the battery pack can reach 150 kWh, and the theoretical CLTC range can exceed 1200km.
Xiaomi's self-developed 9100-ton super die-casting machine Xiaomi.
Xiaomi has even developed its own integrated die-casting technology in the manufacturing process - a new technology led by Musk that is expected to trigger a revolution in automobile manufacturing. In the past, only car companies that have reached a certain mass production scale will roll up this technology. Now that Xiaomi has joined, it can also reflect Xiaomi's long-term determination to build cars, as well as its large investment and wide range of fields.
This cluster equipment covers an area of 840m, with a total weight of 1050t and a clamping force of 9100t. With the cooperation of Xiaomi's self-developed visual large-scale model quality judgment system, the rear floor of Xiaomi cars can achieve 72 parts in one, reduce the number of solder joints by 840, reduce the overall weight by 17%, and greatly reduce production man-hours by 45%.
Investing in a die casting machine looks like a wrist wrestling with Tesla Xiaomi.
In addition to this, Xiaomi has also incorporated a careful machine while saving on manufacturing costs. The use of integrated die-casting models, often for users to repair the cost is higher, Xiaomi car adopts a three-stage repairable design - integrated die-casting rear floor + medium and high speed collapse area + low speed collapse area, in the middle and low speed collision, there is no need to replace large die castings;In high-speed collisions, this design can also meet the 90km h rear collision standard.
Of course, intelligence is the core competitive advantage of technology companies entering the field of smart electric vehicles. In October this year, Xiaomi officially released a new system surging OS that moves towards the whole ecology of people, cars and homes. This is regarded as Xiaomi's core underlying competitiveness in the field of smart cockpits.
At today's press conference, Lei Jun officially announced that the surging OS was on the car, and introduced the car machine system from four dimensions: learning cost, system fluency, software ecology and hardware ecology.
Dimensions and parameters of the central control screen of the Xiaomi SU7 by Xiaomi.
From the user's point of view, what Xiaomi has to do is to make the operation of the car machine system achieve the same effect as operating a mobile phone and tablet. To achieve such an effect, not only the screen needs to be large enough, but also the system needs to be smooth and silky enough. According to the information displayed at the press conference, the starting speed of the Xiaomi car can reach 1In 49 seconds, the mobile phone** meeting can share the external camera, and the in-car reading light can call the light sensor of the mobile phone.
From an experience perspective, it's not enough to just share hardware. In the eyes of developers and system engineers, adapting products to different screen sizes is a trivial matter. Therefore, Xiaomi chose a 16:10 central control screen ratio, which can make the app on the Xiaomi tablet seamlessly onto the car, which solves the difficulty for developers;At the same time, the application of Xiaomi mobile phones can also be directly PIN (cast) to the screen of the car side, and after projection, it supports direct operation on the car side, turning it into a cloud application running on the mobile phone and used on the car side.
The su7 can be connected to the Xiaomi ecological hardware through an electric shock in the cockpit of Xiaomi.
Not only that,Thanks to Xiaomi's rich IoT smart hardware ecosystem,Xiaomi has also left enough hardware interfaces under the central control screen,Four groups of PIN point power supply communication design can expand the physical buttons,You can be smart with Mi home devices without feeling。 What's more interesting is that Xiaomi su7 also fully supports Apple carPlay, and the extended screen interface in the rear row also supports ipad access, Lei Jun said, to let Apple users drive Xiaomi cars, there is also a good experience .
In the field of intelligent driving, Lei Jun mentioned in his personal speech in mid-2022 that he wanted Xiaomi's intelligent driving to rank among the first echelon of the industry in 2024. Today, he re-emphasized this goal and expressed the hope that Xiaomi's self-developed NOA (City Pilot Assisted Driving Function) will open 100 cities by the end of 2024.
The intelligent driving goal of Xiaomi Automobile, next year it will enter the first camp of Xiaomi.
At the technical level, Xiaomi has improved its perception and recognition technologies through three technologies: adaptive zoom BEV technology, road large model, and super-resolution occupancy network technology. In terms of hardware, this intelligent driving system is equipped with 2 NVIDIA Orin high-computing power chips, with a comprehensive computing power of up to 508tops. The MAX model always has 1 lidar, 11 high-definition cameras, 3 millimeter-wave radars and 12 ultrasonic radars, a total of 27 perception hardware.
It is foreseeable that in 2024, a technology company will join this battlefield with strong R&D and AI capabilities.
The body size of the Xiaomi Su7 is 4997mm x 1963mm x 1440mm, the wheelbase is 3000mm, and the overall shape presents a low-lying sports car posture, with a wind resistance as low as 0195cd。At the same time, thanks to the forward-developed pure electric platform, the car also has a 105L trunk volume.
The dual-motor version of the Xiaomi su7 has a zero-hundred acceleration of 278 seconds for Xiaomi.
Thanks to the HyperEngine V6 V6S super motor jointly developed by Xiaomi, the 000 acceleration of the Xiaomi SU7 Max version can reach 278 seconds (minus the start time) while reaching a top speed of 265 km/h. In the Xiaomi Wind Smart Chassis, CDC Damping Variable Shock Absorber, Bosch ESP10With the blessing of many configurations such as 0 body stability system, Bosch DPB brake controller, Brembo four-piston fixed caliper, Lei Jun said that it is not only designed for beauty, but also for driving.
Throughout the press conference, Lei Jun seemed to deliberately avoid the topic of **, and when it was mentioned a few times, Lei Jun also emphasized 990,000 impossible, 1490,000 doesn't have to think about it.
We can simply guess the pricing logic behind it from some of the configuration information that has been revealed so far:
For a smart electric vehicle, the biggest cost is the battery, which accounts for about 40%-50% of the cost of the whole vehicle. The Xiaomi Su7 has two endurance versions, with a range of 668km and 800km in CLTC mode, and the MAX version uses 800V super fast charging, which can reach 220km in 5 minutes of charging.
Lei Jun introduced at the press conference: Ternary lithium (battery cell material ° electricity (battery capacity), CATL, these three elements together mean a cost of more than 100,000 yuan. It can be seen that at least the battery cost of the high-range version of the Xiaomi Su7 is higher.
However, according to the public information of the Ministry of Industry and Information Technology, there seems to be a lot of gap between the two versions of Xiaomi Su7 and Su7 Max in terms of battery, electric drive, and intelligent driving hardware. So, can we imagine getting a model similar to Redmi in the entry-level version of the Xiaomi Su7?
In any case, for Xiaomi and Lei Jun, it took 1003 days to make the official debut of Xiaomi Automobile, which is not only a new test of manufacturing capabilities, but also an all-round management and operation test of a technology company to mobilize the capabilities of past software, systems and other parties. The story of Renchejia is about to usher in a new chapter in 2024, and the story of Xiaomi Auto will also be a new story of Xiaomi Group.
