Year-end epic traffic give, 3 hours to contribute more than 10 hot searches on the whole network, before the release of the public said that it is indeed a bit expensive, there is a reason for expensive, this is Xiaomi's first car - Xiaomi Su7 pre-press conference.
As Lei Jun said: "The goal of Xiaomi Auto is to be comparable to Porsche and Tesla, to create a dream car in the new era, and to make a good mobile intelligent space that looks good, is easy to drive, comfortable and safe." At the same time, starting from the underlying core technology, with the determination of "ten times investment", the ultimate goal is to become the world's top five automobile manufacturers through 15-20 years of efforts. ”
What is the Xiaomi Su7 that was born under such a huge vision?How expensive will it be in the end?We can't help but be a little curious.
Build a car, driven by technology
In this Xiaomi car press conference, Lei Jun did not talk nonsense throughout the whole process, only talked about technical dry goods. From the five parts of intelligent driving, intelligent cockpit, super motor, battery, and integrated die-casting, the entire process of Xiaomi's car manufacturing is comprehensively and meticulously interpreted.
1. The motor mass production generation, reserve generation, and pre-research generation. Lei Jun released a total of 3 Xiaomi self-developed motors this time, the first to be equipped on the Xiaomi SU7 is the V6 and V6S motors, the former has 220kW peak power, 400N·m maximum torque, and is compatible with 400V voltage platform;The latter is 275kW, 500N·m, and is compatible with 800V high-voltage platforms. Both have a maximum speed of 21,000 rpm, which is currently at the leading level in the industry.
At the same time, the Xiaomi super motor V8S will also be mass-produced in 2025, with a peak power of 425kW, a peak torque of 635N·m, and a maximum speed of 27,200rpm. The industry's first 960MPa special silicon steel sheet, fully self-developed fixed rotor design, two-way full oil cold and hot spreading. In addition, Xiaomi Lab has pre-developed a 35,000rpm motor.
2. Top battery in the industryand thermal managementXiaomi SU7 has a 400V lithium iron phosphate battery version and an 800V ternary lithium battery version, of which the latter adopts a 100-degree battery pack developed in cooperation with CATL, and Xiaomi's self-developed CTB body battery integration technology, with a thickness control of 120mm and a volume ratio of 778%, the first cell inverted technology, the maximum charging voltage reaches 871V, double-sided water cooling and heat dissipation, 17 layers of high-voltage insulation protection and other characteristics.
The battery thermal management of Xiaomi cars has also been upgraded to a dual-mode heat pump, which can be used for both dedicated heat and member warehouses, and can also be used for multiple heat supply. Through the step-by-step heating technology of three heat sources, Lei Jun said that "Xiaomi Auto should be the king of winter tram battery life".
3,9100 tons of integrated large die-casting technology. Xiaomi introduced a 9,100-ton super die-casting machine, which is just one size larger than Tesla's 9,000-ton just landed, and jointly developed Xiaomi Titan alloy materials, becoming the first manufacturer in the industry to have both large die-casting and die-casting material formulas. Xiaomi cars will feature a 72-in-1 integrated die-cast rear floor with a three-section rear floor anti-collision design.
Xiaomi Su7 adopts an armored cage steel-aluminum hybrid body design, of which high-strength steel and aluminum alloy account for 901%, the highest strength reaches 2000MPa, which is generally referred to in the industry as submarine-grade steel, the torsional rigidity of the vehicle reaches a terrifying 51000N·m deg, 40 of the latest severe collisions are passed with high standards, equipped with 7 airbags, and is very leading in passive safety.
4. Xiaomi intelligent driving with deep integration of software and hardware. Xiaomi SU7 has an all-aluminum chassis, of which the Max high-end version is equipped with a closed air spring and CDC electromagnetic suspension, through the full-stack self-developed chassis control algorithm, it can achieve road state adaptation, aerodynamic adaptation, corner attitude adaptation, and active flank adaptation.
Lei Jun said: "Xiaomi intelligent driving will enter the first echelon of the industry in 2024." By the end of next year, Xiaomi will open autonomous driving in at least 100 cities. The zoom BEV in Xiaomi's self-developed perception technology dynamically adjusts the perception range in different scenariosThe super-resolution vector algorithm is added to the OCC occupancy network technology, and the accuracy is less than 01m, leading the industry in level, accurately identifying all kinds of special-shaped obstacles.
At the press conference, Lei Jun demonstrated the functions of Xiaomi Automobile's city pilot, unmanned parking, automatic summoning of parking lots, and automatic parking of mechanical parking spaces. Xiaomi SU7 will be equipped with up to Nvidia dual ORINX chips + an overhead lidar, with 27 sensor fusion perception hardware.
5. Closed-loop fully ecologically interconnected Xiaomi smart cockpit. As a Fortune 500 intelligent giant, Xiaomi Innovation vividly shows everyone what a real full-ecological intelligent cockpit is.
16:10 ratio 16-inch 3K OLED central control large horizontal screen, moving the tablet into the car;The head-up display reaches 56 inches and the brightness is up to 13,000 nitsThe rear row supports external expansion of Xiaomi tablets, and the car control screen changes in seconds, supporting various car control functions such as seats, air conditioning, and audio, and comes with 225W charging.
At the same time, a wealth of third-party external expansion ports are embedded everywhere in the car to support the interconnection of more than 1,000 kinds of Mijia ecological devices, fully open standards, and support manufacturers to actively access.
Xiaomi Su7 is equipped with the latest Qualcomm Snapdragon 8295 cockpit chip, pre-installed surging OS, and the average starting speed of the car machine is only 1In 49S, it only takes 3 minutes to upgrade the OTA of the cockpit and 30 minutes to upgrade the OTA of the whole vehicleIt not only supports Xiaomi mobile phone handcar interconnection , but also supports Apple CarPlay, AirPlay, and even allows the iPad to seamlessly change into the car machine control screen in seconds.
There is no doubt that the cross-terminal integration and interconnection of Xiaomi cars and Xiaomi ecology is indeed full of imagination and various surprises.
How much will the Xiaomi Su7 sell for?
After reading the overall configuration and functions of Xiaomi Su7, combined with the justified expensive that Lei Jun has been emphasizing, plus the 9 that Lei Jun has already denied9w、14.99W and other netizens speculated**, today we will boldly guess the final price of Xiaomi Su7.
It is known that Xiaomi Su7 has two major versions, Pro and Max, with a body size of C-level, 4997x1963x1440mm, a wheelbase of 3 meters, and a drag coefficient of 0195cd。The Pro version uses 736 degree lithium iron phosphate battery, 400V voltage platform, single motor rear drive, fabric roof. The MAX version uses a 101-degree ternary lithium battery, an 800V high-voltage platform, dual-motor four-wheel drive, and a 000 acceleration of 278s, with air suspension, electric rear wing, multi-piston Brembo calipers, lidar, microfiber headliner, etc.
First of all, it can be clearly seen that the Pro version configuration is more castrated than the MAX version, and the just-released ZEEKR 007 75 degree 800V lithium iron phosphate battery single-motor rear-drive version is priced at 20990,000 yuan, Xiaomi Su7 Pro version is obviously inferior to 007, but the size space is slightly larger, so the preliminary ** its price will eventually be around 200,000 yuan.
ZEEKR 007 upgrade 100 degree 800V ternary lithium battery pack needs to increase the price by 20,000 yuan, and then multiple motors, silicon carbide SiC controllers, etc., the cost is increased by 10,000 yuan, lidar plus 10,000 yuan, air suspension plus about 20,000 yuan, electric tail, microfiber roof and other configurations plus 2 30,000 yuan, the final MAX version will be 7 90,000 yuan more expensive than the Pro version, and the final price may exceed 300,000 yuan.
Finally, from the perspective of Xiaomi's main ultimate cost performance and the need for the first car to assume the historical responsibility of the brandPricing for the Xiaomi SU7 Pro version or at 1899～20.990,000 yuan, while the Xiaomi SU7 Max version is priced at 2999～31.990,000 yuan.
Of course, the above is just a personal guess. Do you think this ** meets your psychological expectations?Or you might as well share your guesses in the comments section.
