Xiaomi’s “Dream Car”: High-Tech, High-End, and High-Priced?

After three years of preparation, Xiaomi’s first car finally officially appeared.

On December 28,2023, three days before the new year, Lei Jun, founder, chairman and CEO of Xiaomi Technology, exposed Xiaomi’s first car, SU7, which has been highly anticipated and “spoiler”.

The price of the product that is much concerned has not been announced, and even in the few times when the price is mentioned, Lei Jun also emphasizes that “99,000 is impossible, and 149,000 is not necessary.”

But the three-hour speech still caught everyone’s attention.Lei Jun gave the positioning of Xiaomi’s first car: “Dream Car comparable to Porsche and Tesla”, and built it with five dimensions of R & D stories and product functions, explaining the 1003-day car-building story.

At the end of 2023, such narrative methods seem to be somewhat out of place with the internal environment of smart electric vehicles in China.But such a “leap” story is what today’s Xiaomi cars need: cost performance is no longer the main direction of this enterprise, and continuous exploration on the road of high-end is the goal of the future.

Lei Jun said: “In 1003 days, it is easy to ‘accumulate’ a car, but it is not easy to develop it positively.”At the press conference, he introduced the R & D story of Xiaomi Automobile from five dimensions: battery, electric drive, large die casting, intelligent driving and intelligent cockpit.”I want to walk with the elites of the times.”Xiaomi SU7 launch conference PPT wrote so.

01 positive research and development, Xiaomi is not to “save” a car

As a technology company, Xiaomi’s investment in automobile mechanization, electrification, manufacturing and other fields is somewhat unexpected.

In the field of electric drive, Xiaomi spent more than two years developing the HyperEngine V6/V6s super motor, ranking first in the industry at 21000rpm, surpassing Tesla Model S Plaid.At the same time, another HyperEngine V8s super motor with a speed of up to 27200rpm is expected to arrive in 2025.

It is worth mentioning that in order to break through the physical performance of the rotor at high speed, Xiaomi and Shougang have established a joint technical laboratory 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 CTB integrated battery (i.e. battery and vehicle floor integrated) battery.The battery pack has a maximum capacity of 150 degrees and a theoretical CLTC range of more than 1200km.

Xiaomi has even developed integrated die-casting technology in its manufacturing process-a brand-new technology led by Musk that is seen as promising to revolutionize car manufacturing.In the past, only “car companies” that reached a certain mass production scale would roll out this technology.Now Xiaomi joins, can also reflect Xiaomi’s long-term determination to build cars to some extent, as well as the large investment, the wide range of fields.

The cluster equipment covers an area of 840m², weighs 1050t and has a clamping force of 9100t.With the cooperation of Xiaomi’s self-developed vision large model quality judgment system, 72 parts can be integrated into the rear floor of Xiaomi car, 840 solder joints can be reduced, the overall weight can be reduced by 17%, and the production time can be greatly reduced by 45%.

Picture investment “Die casting machine” looks like it is in arm wrestling with Tesla| In addition to this, Xiaomi also added a “careful machine” while saving manufacturing costs.The model with integrated die-casting often has higher maintenance cost for users. Xiaomi Automobile adopts three-stage maintainable design_integrated die-casting rear floor + medium and high speed collapse zone + low speed collapse zone. In medium and low speed collision, there is no need to replace large die casting; in high-speed collision, this design can also meet the rear collision standard of 90km/h.

02 Intelligent: Enter the first echelon in 2024

Of course, intelligence is the core competitive advantage for technology companies to enter the field of smart electric vehicles.In October of this year, Xiaomi officially released a brand-new system surging OS towards the full ecology of “people’s car home”.This is seen as Xiaomi’s core underlying competitiveness in the smart cockpit field.

At today’s press conference, Lei Jun officially announced that the surging OS was on board, and introduced the car system from four dimensions: learning cost, system fluency, software ecology and hardware ecology.

Picture Xiaomi SU7’s central control screen size and parameters| Xiaomi from the user’s point of view, millet to do is to let the operation of the car system to achieve the same effect as the operation of mobile phones, tablets.To achieve this effect, not only does the screen need to be large enough, but the system needs to be smooth and smooth enough.According to the information displayed at the press conference, Xiaomi’s car can start at a speed of 1.49 seconds, mobile video conferences can share cameras outside the car, and in-car reading lights can call light sensors on mobile phones.

From an experience perspective, sharing hardware alone is not enough.Adapting products to different screen size is trivial in the eyes of developers and system engineers.Therefore, Xiaomi chose a 16:10 ratio of the central control screen, which can make the App on the Xiaomi tablet seamlessly get on the car, solving the difficulty of the developer; at the same time, the application of Xiaomi mobile phone can also be directly Pin (projection) to the car screen, and after projection, it supports direct operation of the car end, becoming a “cloud application” running on the mobile phone end and using the car end.

Photo SU7 can be connected through the electric shock and Xiaomi ecological hardware in the cockpit| Xiaomi not only that, thanks to Xiaomi’s rich IoT intelligent hardware ecosystem, Xiaomi also set aside enough hardware interfaces under the central control screen, four groups of Pin point power supply communication design can expand physical buttons, can and Mi home equipment without feeling flexible.More interesting is that millet SU7 also fully supports Apple CarPlay car, and the rear expansion screen interface also supports iPad access, Lei Jun said, to let “Apple users open millet car, also have a good experience.”

In the field of intelligent driving, Lei Jun mentioned in his personal speech in mid-2022 that Xiaomi’s intelligent driving should be ranked as the first echelon in 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 smart driving goal of Xiaomi Automobile will enter the first camp next year.| Xiaomi at the technical level, Xiaomi through adaptive zoom BEV technology, road large model, super resolution occupied network technology three technologies, respectively improved perception and recognition technology.In terms of hardware, this intelligent driving system is equipped with two Nvidia Orin high-computing chips, with a comprehensive computing power of up to 508TOPS.Max models always have 1 lidar, 11 HD cameras, 3 millimeter wave radars and 12 ultrasonic radars, totaling 27 sensing hardware.

It can be predicted that in 2024, a technology company will join the battlefield with strong R & D and AI capabilities.

3 Why is it “a little expensive”?

The body size of Xiaomi SU7 is 4997mm x 1963mm x 1440mm, and the wheelbase is 3000 mm. The overall shape presents a low-lying sports car posture with wind resistance as low as 0.195Cd.At the same time, thanks to the pure electric platform being developed, the car also has a 105L front spare box volume.

Xiaomi is equipped with HyperEngine V6/V6s super motor jointly developed by Xiaomi. Xiaomi SU7 Max version can accelerate to 2.78 seconds (minus starting time), and the maximum speed can reach 265km/h.With the addition of Xiaomi Gale intelligent chassis, CDC damping variable shock absorber, Bosch ESP10.0 body stability system, Bosch DPB brake controller, Brebo four-piston fixed calipers and many other configurations, Lei Jun said that “not only designed for beauty, but also designed for driving.”

The whole conference, Lei Jun seems to deliberately avoid the price of this topic, in the few mentioned, Lei Jun also stressed that “99,000 impossible, 149,000 do not have to think about.”

We can simply guess the pricing logic behind some of the configuration information revealed now:
For an intelligent electric vehicle, the biggest cost lies in the battery, which accounts for about 40%-50% of the vehicle cost.Xiaomi SU7 has two battery life versions, CLTC operating range of 668km and 800km respectively, MAX version uses 800V super fast charge, charging 5 minutes can reach 220km.

Lei Jun introduced at the press conference: “ternary lithium (battery material), 100° electricity (battery capacity), Ningde era, these three elements together, means a cost of hundreds of thousands.”It can be seen that at least the battery cost of the high-endurance version of Xiaomi SU7 is higher.

However, according to the Ministry of Industry and Information Technology public information, Xiaomi SU7 and SU7 Max two versions, in the battery, electric drive, intelligent driving hardware, seems to have a lot of gap.So, can we imagine getting a model similar to “Red Rice” in the entry version of Xiaomi SU7?

In any case, for Xiaomi and Lei Jun, it takes 1003 days for Xiaomi to officially debut, which is not only a brand-new test of manufacturing ability, but also an all-round management and operation test for a technology company to mobilize past software, systems and other capabilities.The story of people and cars will usher in a brand-new chapter in 2024. The story of Xiaomi Automobile will also be a brand-new story of Xiaomi Group.
