Three years, a total of 1003 days, Lei Jun took the initiative to unveil the first veil of Xiaomi cars to the public for the first time.
A few days before the press conference, Lei Jun posted on Weibo that the conference "only talks about technology, not products". But perhaps moved by the enthusiasm of the rice fans, or thinking that continuing to hold back would be detrimental to the product launch, Lei Jun still couldn't help but talk a lot about the su7.
During the almost three-hour launch,Lei Jun talked about the motor, battery, die-casting, intelligent driving and intelligent cabin technology that Xiaomi Auto has precipitated in the past three years, and also talked about the size, appearance, interior and other details of Xiaomi Su7, the first product of Xiaomi AutomobileThis article will introduce and analyze each of them.
Su7, Lei Jun called it "Su7", and said that he called the product so to make the product name more humane.
But contrary to such a kind, peaceful, and humane name,Judging from the various configurations of the Su7, perhaps the first product of Xiaomi Auto will be "relatively expensive" as Lei Jun said, Xiaomi, which has always been cost-effective, is finally going to refuse to give a low price to "make a friend" this time?
Intelligent cockpit: hardware expansion plays
Let's talk about Xiaomi itself first, which is also the area that the public is best at by default: smart cockpit.
As we all know, no matter how mobile phone manufacturers participate in the smart cockpit business, it is basically a dimensionality reduction attack.
However, unlike the early Huawei and today's Meizu, Xiaomi is fully responsible for every aspect of vehicle design and manufacturing, and its intelligent cockpit is relatively more "playful".
Xiaomi Auto has not named its smart cabin system for the time being, and will call it the surging cockpit for the time being.
The biggest feature of the surging cockpit is the scalability at the hardware level, that is, cariot.
Although a piece of 16The 1-inch, 3K resolution central control screen can already meet most of the car control and entertainment functionsHowever, Lei Jun said that PIN points are reserved around the central control screen, which can realize plug-and-play for other devices. For example, mechanical button enthusiasts can plug in the mechanical button center console as shown in the figure below.
There are pin points around the central control screen to connect external devices.
And the same hardware expansion contacts are all over the car, such as the pin point power supply is also reserved in the storage space under the center console, and Xiaomi or Apple tablet devices can also be hung behind the front seatsRear passengers can easily control the front and rear seat positions and seat functions, and even front passengers can call on the rear flat camera to observe the safety of rear passengers.
Lei Jun said that Xiaomi Cariot will also be open to third parties to cooperate, and has reached a cooperation with a child seat manufacturer"At the time of the official launch, there will be a few more for everyone.
10. Hundreds of hardware ecological expansion. ”
With the support of Cariot, the surging cockpit can be interconnected with child seats and rear tablets.
In addition, the interconnection of the surging cockpit with Xiaomi devices is also essential. Lei Jun introduced that all Mijia devices can be used under the same account to get on the car without password and without feeling.
The interconnection between the mobile phone and the car machine is very smooth: the navigation of the mobile phone page, Feishu documents, etc. can flow to the car and machine without feeling, and even if the car machine does not have a corresponding application, the application that the user is browsing on the mobile phone can still be presented as an independent card in the car screen.
In the surging cockpit, other functions such as three-point screens that are independent of each other and flexible in size, and the main and co-pilots can directly display the control center when they slide down, and other functions that reduce the user's learning threshold can only be said to be basic skills for mobile phone manufacturers like Xiaomi.
However, it is worth noting that Xiaomi SU7 is equipped with Qualcomm Snapdragon 8295 chip, which has a great improvement in GPU computing power, soXiaomi also made a full 3D rendering of the car machine desktop and added a weather system.
SU7 central control screen desktop weather system.
An intelligent cockpit engineer has previously said,Full 3D desktop and weather rendering are very computing power-intensive, "After weighing the actual value [of 3D rendering] brought by it, we still chose to use the excess computing power for functions related to assisted driving. ”
However, Lei Jun thinksThis feature is one of the most luxurious features in the car, along with the reversible instrument cluster, physical button-controlled electric rear wing and suspension in the cabin.
On the one hand, Xiaomi Su7 is the first product of Xiaomi Automobile, and in such a competitive market environment, it must be successful when it comes to shooting, so it is necessary to fill the product in all aspects.
On the other hand, Xiaomi Su7 is also equipped with two NVIDIA Orin-X chips in terms of intelligent driving, and there is no need to be overly careful about computing power.
Intelligent driving: It is not easy to enter the head camp
After talking about Xiaomi's best areas, let's talk about Xiaomi's highly-anticipated intelligent driving system Xiaomi Pilot (XP).
In terms of intelligent driving hardware, Xiaomi's intelligent driving platform uses a combination of two Orin-X chips, a lidar, eleven high-definition cameras, three millimeter-wave radars and twelve ultrasonic radars, and the configuration is not much different from the current mainstream head intelligent driving players.
XP System Smart Sensor Configuration.
The more eye-catching feature is today's more popular valet parking.
Lei Jun saidThe XP intelligent parking system adopts an end-to-end perception and decision-making modelIt can greatly reduce the error of traditional perception decision-making, "relying on the large model to fine-tune several times after the initial decision and initial alignment, so as to achieve accurate parking." ”
Lei Jun also said that his engineers tested an overnight test and that the XP automatic parking system had a 0% failure rate when dealing with a mechanical garage with a unilateral width redundancy of only 5cm.
In addition to precise parking, the XP intelligent parking system also:Do cross-layer parking, U-turn parking, reverse avoidance, obstacle detour, etc.
In terms of urban and high-speed NOA, Lei Jun also demonstrated XP through **Automatic overtaking, large vehicle avoidance, unprotected left and right turning, construction avoidance and other functions. In addition,The XP will also provide features such as on-ramp, adaptive cornering, automatic overtaking, junction and construction avoidance.
From the functional point of view, or from the demo ** and PPT content, at the current stage when the penetration rate of NOA functions is still in single digits, Xiaomi Auto XP is fully able to enter the market and come to the first camp.
The goal is ambitious, but there are no shortcuts.
But from past experience, there is no real shortcut to intelligent driving.
Xiaomi is lucky, Huawei Xiaoli and Tesla have explored the mature route of bicycle intelligence in the emerging stage: BEV + Transformer + occupy the network.
Lei Jun said that at presentXiaomi has more than 1,000 intelligent driving teams, more than 3,000 AI teams, more than 200 test vehicles, and more than 10 million kilometers of accumulated test mileage.
However, this route still requires the accumulation of data and the polishing of algorithms. Even if more than 200 test vehicles run data 24*7, they cannot collect enough high-quality long-tail scene data to feed back the iterative upgrade of the intelligent driving system.
Moreover, there are as many basic scientific research resources as Huawei, and it took two or three years to complete the entry to overtaking in the field of intelligent drivingIt is not realistic for Xiaomi Auto to be on a par with the top players in terms of intelligent driving in the early stage of entering the market.
Some relevant people also believe that Xiaomi's basic scientific research and Huawei are not of the same magnitude, "If you want to enter the head camp, it will take a while." It also relayed that people from Nvidia commented that the Xiaomi XP experience at this stage is not as good as expected
Intelligent driving function, Xiaomi still needs to take its time step by step.
Motor, battery, die-casting: directly full
If you want to use two words to describe the technical reserves and product quality of Xiaomi cars in terms of hardware, that is:Pull full.
Let's take a look at a set of numbers first: Xiaomi V6S motor has a maximum speed of 21000rpm and a power density of 678kw/kg；871V silicon carbide high-voltage platform, up to 150kWh with charge, up to CLTC range of 1200+km;9100t integrated die-casting machine, 72-in-1 integrated die-casting rear bottom plate and alloy materials selected from 10.16 million formulas.
The above data is what Lei Jun called "10 times the investment".
Specifically, in terms of motors, according to Lei Jun's words, "Xiaomi Automobile's self-developed motors, and the three generations of motors are developed at once", respectivelyThe V6 and V6S, which are already ready for mass production and will be officially launched in the car, are both 21,000rpm, corresponding to the 400V version and the 800V versionThe V8S will be launched in 2025 with a maximum speed of more than 27,000 rpmThe next generation of motors, still in the laboratory stage, has a maximum speed of 35,000 rpm.
Xiaomi motor technology reserves.
Interestingly, Xiaomi's high-speed motor was intercepted by a friend. Previously, Huawei has just released a new generation of motors with speeds of up to 22,000rpm.
Although Hu was intercepted, Lei Jun released a more ruthless material: V8S motor.
The V8S motor can reach a maximum speed of 27,200rpm, Lei Jun revealedThe Xiaomi V8S uses a silicon steel material with a strength of 960MPa and two-way stereo oil cooling technology to create the motor"The V8S will be mass-produced in 2025. ”
Not only that, Lei Jun revealed that in the laboratory, the team has used laser winding rotor technology to develop a motor with a maximum speed of 35,000rpm.
Although the latter two motors are still far from being officially on the car, now Xiaomi SU7 has been able to be blessed with the V6S motorGive 100 km/h acceleration 2In 78s, it has a top speed of 265 km per hour, a maximum torque of 838 Nm, and a maximum horsepower of 673 PS.
In terms of battery, Xiaomi Auto has also adopted the CTB integration technology that has gradually become the mainstream, which has reduced its battery pack wiring harness by 91% and saved 3% of the space.
The result is the theoretical upper limit of the battery pack's 150kWh charge and a range of more than 1200km. Under the existing mature battery system, the battery pack can also provide a charge of up to 132kWh and a range of more than 1000km.
At the same time, Xiaomi also pioneered the inverted cell structure with CATL, which reduces the harm caused to the cockpit when the battery cell is damaged. ”
A battery engineer also revealed that the structural technology of cell inversion will soon be applied on a large scale in new power models.
Cell inversion technology is about to be put on a large scale.
In addition, Xiaomi Auto has also adopted the integrated die-casting technology that is sought after by the industry, "Xiaomi has placed an order for two sets of 9100T integrated die-casting machines, which run together with the traditional stamping method and are redundant with each other. ”
In horizontal comparison, the integrated die-casting machine used by Xiaomi Auto is not the most in the industry: Xpeng X9 has used a 12000T die-casting machine, and Nezha is also planning to apply a 20000T die-casting machine.
Xiaomi, which is not as good as its competitors in terms of numbers, has put a lot of thought into materials.
Lei Jun revealed that in order to make better use of the integrated die-casting machine, Xiaomi chose self-developed die-casting materials, "in cooperation with the national key materials laboratory, developed a high-quality solution from 10.16 million formulas", Lei Jun named it Xiaomi Titan Alloy.
In the end, the Xiaomi Titan Alloy and 9100T integrated die-casting machine also contributed a 72-in-1 rear floor to Xiaomi Auto, which can reduce the noise in the car by 2db and reduce the weight by 17%.
In addition, Lei Jun revealed that in order to prevent the integrated die-casting technology from causing "one crash destroys all", Xiaomi has designed a three-stage anti-collision design for the integrated die-casting rear floor, which deals with rear-end collisions under low-speed and medium-high speed working conditions.
Xiaomi integrated die-casting three-section rear floor.
The integrated die-casting technology will also optimize the trunk space. Lei Jun said that the SU7 is equipped with an integrated die-casting triangular beam, which combines 18 parts into one, and cooperates with the design of the three-electric system and the inclined radiator, so that the SU7 has a front trunk with a volume of up to 105L.
If the configuration is full, can I still make friends?
It's hard to say about the intelligent driving function, but it can be seen that in terms of smart cabin, motor, battery and die-casting, Lei Jun did directly fill the configuration on the first car.
What is certain is that the above technical reserves will be applied to the Su7.
In addition, there are some configurations that are worth mentioning. For example, Xiaomi Su7 in the interior and exterior design of the vehicle, hired Li Tianyuan, Qiu Zhen and others who have designed many models for BMW and Mercedes-Benz, which makes the SU7 vehicle proportion and interior more attractive.
And,The design team also made the SU7 as low as 0Drag coefficient of 195cd.
In addition, Lei Jun also introduced the family-style design of the SU7For example, waterdrop headlights, halo taillights, 175° ripple curved surfaces and semi-hidden door handles, these designs are likely to continue to the next products of Xiaomi Auto.
But there is no ** how rich and outstanding the design isConsumers' judging criteria for whether Lei Jun is really sincere are still **.
Previously, Lei Jun had said on Weibo that the upcoming SU7 "may be a little more expensive", and this time he personally admitted at the event: "Don't say 9."90,000 made a friend, impossible, 14The same goes for 90,000. ”
From the perspective of various configuration functions, rationally speaking, such a SU7 is definitely not a 100,000-150,000 yuan level car. If it was placed a year ago, even if the price was 300,000 yuan, some people would say that it was cheap.
But at the end of 2023, and even in 2024, when the ** war is likely to usher in an escalation, as long as the pricing is not sincere enough, neither friends nor consumers will give Xiaomi Auto a second chance.
How to give the most sincere ** within the acceptable range of consumers, and at the same time make consumers feel that "expensive and expensive" has become a problem for Lei Jun.
Judging from the configuration table in the picture above, Xiaomi Su7 will be roughly divided into a 400V single-motor version and an 800V dual-motor versionThe former is equipped with 736kWh lithium iron phosphate battery and an NVIDIA Orin-X chip, the latter will be equipped with a 101kWh ternary lithium battery and two NVIDIA Orin-X chips, and will also have LiDAR, air suspension, HUD, electric rear wing and other configurations.
It can be seen that Lei Jun's specific pricing ideas for Xiaomi Su7 are gradually becoming clear:Widen the gap between high and low configurations.
In this way, you can put down the burden and let the entry-level configuration really have the ** of the "beggar's version", while maximizing the premium ability of those additional configurations in the top version.
Such a party ** has long been proven by M7. The difference between the M7 entry version and the top intelligent driving version is 60,000 yuan, and among the 70,000 big orders harvested in more than a month on the market, the highest proportion is the lowest configuration and the top version, and the two configurations meet the needs of two types of users: the pursuit of cost performance, and the pursuit of intelligent driving.
At present, the Xiaomi intelligent driving system XP has not proven itself, and it cannot ensure that it will eat the widely sought after dividends of today's intelligent driving, so the two types of people that Xiaomi Su7 high and low configuration strive for have becomeThe pursuit of cost performance, as well as the pursuit of ultimate performance.
SU7 performance parameters.
Considering that the sports attribute is still a difficult story to tell in the domestic market,The difference between the high and low configurations of Xiaomi cars may be controlled at about 60,000-70,000 yuanThis not only widens the gap between the two, but also ensures that the overall price of the high-spec version of the high-end model, which focuses on the performance label, is not too high.
Once you've figured out this idea, the only thing you need to consider is the pricing of the entry version.
What is certain is that 9It is impossible to make a friend with 90,000 yuan, so do you need to get closer to the ** line of 200,000 yuan?
ZEEKR, which has not been paid tribute to by Xiaomi cars, may have given the best answer: 20990,000 yuan.
If Lei Jun adheres to the concept that the first product is only allowed to succeed and not to fail, he must be ruthless to himself and his team.
If you figure this out, then the above question is not whether you need to get closerIt's a question of how close it needs to be, and whether it even needs to come below 200,000 yuan.
