On December 28, Xiaomi Group held a Xiaomi automotive technology conference in Beijing, which immediately swept all major platforms. In order to make a dream car comparable to Porsche and Tesla, Xiaomi Auto disclosed five core technologies this time, and the first car Xiaomi Su7 was officially unveiled.
On the car track that has been rolled to the extreme, Xiaomi Auto has set up a new flag!Lei Jun, founder, chairman and CEO of Xiaomi Group, said that Xiaomi Auto is a major leap for Xiaomi Group from the mobile phone industry to the automotive industry, and it is also a key leap for the complete closed-loop of "people, cars and homes". Xiaomi decided to invest tenfold, starting from the underlying core technology, seriously building a good car, and through 15 to 20 years of hard work, it will become one of the top five car manufacturers in the world!
Five core technologies
Electric drive. Released three super motors: HyperEngine V8S and HyperEngine V6 V6S.
HyperEngine V6 V6S super motor ranks first in the industry with a speed of 21,000rpm. 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.
HyperEngine V8S super motor with a speed of up to 27,200 rpm and a power density of 10At 14 kW kg, it has an impressive high power output of 425 kW and a peak torque of 635 Nm.
Battery. Xiaomi's self-developed world's first inverted CTB integrated battery has a battery capacity of up to 150 kWh and a theoretical CLTC range of up to 1200km+.
The Xiaomi car CTB integrated battery uses a floor cover with two combinations.
1. The design of inverted battery cells, multi-functional elastic interlayer and minimalist wiring harness, 165 pieces of aerogel thermal insulation material with double large surface strong cooling scheme, and full-stack self-developed battery management system will become the king of winter tram endurance.
Large die casting. Xiaomi's self-developed 9100T super large die-casting technology, Xiaomi Hypercasting, has become the only automobile manufacturer in China that independently develops both "large die-casting equipment cluster" and "die-casting materials".
The clamping force of the equipment has reached the top of the industry at 9100t. In terms of material research and development, the optimal alloy formula is selected from 10.16 million formulas to ensure the perfect combination of strength, toughness and stability.
To solve the pain point of "high maintenance cost", a three-stage repairable design is adopted: integrated die-casting rear floor + medium and high speed collapse area + low speed collapse area. In low- and medium-speed collisions, there is no need to replace large die castings;In high-speed collisions, this design can meet the rear bump mark of 90kmh.
Intelligent driving. Adaptive zoom BEV technology, road large model, and super-resolution occupancy network technology constitute the three key technologies of Xiaomi's intelligent driving. In terms of hardware, it is equipped with top-level 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).
Xiaomi's goal is to be among the first echelon of the industry in 2024.
Smart cockpit. The intelligent cockpit, as the last link of the whole ecology of people, cars and homes, officially transforms the car into a key carrier of an advanced mobile intelligent space. The cockpit is equipped with 161-inch 3K ultra-clear central control screen, 56-inch large HUD head-up display and 71-inch flip instrument screen.
Mijia devices are on the car without feeling, Xiaoai is fully controlled, and Apple users are equally friendly.
Xiaomi Su7
Appearance. The exterior is in three body colors: bay blue, elegant gray and olive green. 28-degree front windshield, 17-degree large slipback and the continuous curvature of the whole car contour G4, coupled with the frameless waterdrop rearview mirror and goose warm stone lidar design, create Xiaomi SU7 "the lowest wind resistance in the world's mass-produced car" - 0195cd, with very low energy consumption and ultra-high battery life.
The dimensions are 4997mm x 1963mm x 1440mm, the wheelbase is 3000mm, the trunk volume is 517L, and the trunk volume is 105L.
Performance. The Xiaomi SU7 Max version adopts dual-motor all-wheel drive, with a peak torque of 838N·m, a total power of up to 495kW, a top speed of 265km h, and a 0-200km h acceleration of only 10In 67 seconds, the acceleration from zero to 100 is as fast as 278 seconds (minus start time).
Front double wishbone rear five-link independent suspension, equipped with Xiaomi Wind intelligent chassis, equipped with CDC damping variable shock absorbers, Bosch ESP100 body stability system, Bosch DPB brake controller, Brembo four-piston fixed calipers and many other super configurations, turning radius 57 meters, 100 zero braking distance 333 meters.
The two endurance versions have a range of 668km and 800km respectively under CLTC mode, and the MAX version uses 800V super fast charging, which can reach 220km in 5 minutes of charging, truly optimizing performance and performance.
Safe. Xiaomi Mi SU7 is equipped with an armored cage steel-aluminum hybrid body, and the proportion of high-strength steel and aluminum alloy in the body is as high as 901%, the torsional rigidity of the vehicle reaches 51000N· m deg, which fully meets the double five-star safety standards of China and Europe.
Xiaomi's CTB integrated battery technology has top-notch heat dissipation and thermal insulation design, as well as the world's most stringent battery safety testing and 14-layer hard-core physical protection, as well as Xiaomi's vehicle-cloud collaborative safety early warning system and other technical support.
Intelligent. can be seen, seen accurately, and understood", making high-speed and urban intelligent driving more accurate and safer, solving the existing problems of urban NOA intersection difficulties, and creating an urban pilot technology that is applicable to the whole country.
16.1-inch 3K resolution central control ecological screen, 56-inch HUD, automotive grade 71-inch flip-type instrument screen, Xiaomi Pad rear expansion screen with 2 native car machine systems, matching Snapdragon 8295 cockpit chip, AI computing power 30TOPS, and five-screen linkage, bringing the ultimate smooth human-vehicle interaction experience.
Ecology. Focusing on the application ecology, hardware ecology and Xiaomi cariot ecology, Xiaomi Su7 realizes the closed loop of "people, cars and homes", and the mobile phone application is pinned into the car, which can instantly become a native application of the car machineIt has advanced ecological application expansion capabilities, supports more than 1,000 Mijia devices to get on the car without induction, and more than 5,000 applications are gradually adapted and sharedFully open to the three parties, unified standardized interface, full support for wireless CarPlay, adaptation to iPad accessories and applications.
In the future, Xiaomi will open up all scenarios such as home, office, and travel.
Xiaomi finally handed over the preliminary answer sheet for building a car at the end of the year, of course, the most interesting must be **. After all, Xiaomi's products have always focused on a cost-effective product, but the main benchmarks of Xiaomi at this conference are Tesla and Porsche, Lei Jun has also emphasized many times that it will be a little expensive and cannot be lower than 1490,000, not to mention the 9 that netizens jokingly called90 thousand. It is foreseeable that next year's car market will not have the most volume, only more volume, and wait and see the ** and rights and interests of Xiaomi Su7 !!
