According to NIO's official news, at the 2023 NIO Day held on December 23, NIO ET9 was officially unveiledThe pre-sale price of the new car is 800,000 yuan, and delivery is scheduled for the first quarter of 2025.
Weilai Li Bin introduced,Car owners can enjoy 5,000 yuan to 10,000 yuan rights and interests and 100 hours of NIO's high-end exclusive driver service.
The new car is positioned as an executive four-seater flagship sedanIt integrates new technologies such as NIO's global 900V high-voltage architecture and Tianxing chassis system.
It is reported that NIO ET9 is a 900V global high-voltage platform, with a peak charging power of 600 kilowatts, a charge-discharge rate of 5C, and a 46105 large cylindrical battery is used in the power battery part, with an energy density of 292 watt-hours per kilogram.
At the same time, the chassis part of the NIO ET9 adopts the Tianxing Skyride full active suspension, with rear-wheel steering function, and the steering part adopts full steer-by-wire technology, and the steering wheel only needs to hit 0 when parking6 laps.
In terms of appearance, the NIO ET9 is 5,325 mm long, 2,016 mm wide, 1,620 mm high, and has a wheelbase of 3,250 mm.
Li Bin saidNIO ET9 brings together the world's top technologies, which is a well-deserved administrative flagship, and even more so, a well-deserved technological flagship.
The following are the technical highlights of NIO's ET9 debut:
The ET9 is the first to be equipped with the "Skyride chassis system", the world's first integrated hydraulic fully active suspension system, using steer-by-wire system and rear-wheel steering as standard
Equipped with NIO's first self-developed intelligent driving chip "Shenji NX9031", 5nm automotive specification process, the performance exceeds the industry's flagship 25 times;
The global 900V high-voltage architecture, super charging and fast change, has the highest voltage of 925V, the peak charging power of 600kW, and the charging peak current of 765A
NIO self-developed 46105 large cylindrical battery, with 5C flash charging capacity, can charge 255 kilometers in 5 minutes;
Equipped with a new intelligent high-definition projection headlight, with intelligent tracking light carpet, intersection blind spot prompt and other functions;
ET9 pioneered seven layers of safety redundancy for passenger cars, including drive, braking, steering, perception, computing, communication, and power distribution redundancy. ”
On the outside, the NIO ET9 adopts the design language of the NIO family, retaining the iconic one-piece X-Bar and Double DASH daytime running lights.
It is equipped with MIRCO LED intelligent high-definition projection headlights, with intelligent tracking light carpet, intersection blind spot prompts and other functions;In addition, it prevents oncoming drivers from being disturbed by high beams, and has functions such as lane markings, which greatly improves driving safety at night.
At the same time, the new car has added a dual-sided wide-angle lidar, which is integrated with metal fenders on both sides, which not only improves safety but also improves the ability to assist driving.
ET9 adopts an innovative flying body design, with a body size of 5325 2016 1620mm, a wheelbase of 3250mm, and is also equipped with the largest 23-inch wheels in its class, with an outer diameter of 790mm and a ground clearance of 200mm.
The interior of the car is still in the development stage and has not yet been disclosed, but judging from the demonstration, the NIO ET9 uses a rectangular steering wheel for the first time, and debuts a full-range AR head-up display system, which can achieve the equivalent of 120-inch AR-HUD at a telefocus of 15 meters.
As an executive flagship sedan, the NIO ET9 adopts a four-seat layout and creatively adopts the design of "Sky Bridge" and "Administrative Island".
Its first-of-its-kind administrative bridge runs through the front and rear rows, with a length of nearly two meters, integrating 20 innovative subsystems, becoming a bridge for communication and interaction between passengers throughout the car.
The second row is even more innovative, the second row of the versatile executive table supports 360° stepless adjustment, which can cope with multiple scenarios such as reading and office, meeting conversations, presentations and sharing, and the administrative bridge integrates a smart refrigerator with electric opening and closing, and the temperature adjustment range of nearly 10L large space is from minus 2 degrees to minus 55 degrees.
The first class seats in the rear flight have 24 self-developed patents, a maximum backrest adjustment angle of 45°, a seat cushion width of 582mm, a one-key relaxation and 11 linkage adjustments, and the experience is far beyond the same level.
Rear NIO Link Panoramic Connected Administration, App 14The 5-inch OLED high-definition display, the screen angle can be adjusted with the seat position, and the best viewing angle can be obtained in any posture, and the whole car is also equipped with seven electric sunshades, which can be opened with one button.
In terms of intelligence, NIO ET9 is equipped with ** supercomputing platform 20, equipped with NIO's first self-developed intelligent driving chip "Shenji NX9031", 5nm automotive specification process, performance exceeds the industry's flagship 25 times, supporting the computing functions of 6 major sectors, including intelligent driving, intelligent cockpit, intelligent chassis, body, power, and cloud domain.
NIO said that the core components of intelligent driving should not only meet the current needs, but also consider whether they can match the end-to-end large model algorithm in the future, so the intelligent driving chip must meet the algorithm evolution needs for at least 5 years.
And the chassis part,ET9 is the first to ride NIO's newly released "SKYRIDE" full-wire-controlled intelligent chassis, which is currently the world's only full-wire-controlled intelligent chassis system.
For the first time, it integrates the three core hardware systems of steer-by-wire, rear-wheel steering and fully active suspension, and each shock absorber is highly integrated with independent electro-hydraulic pumpsInformation processing, calculation and response can be completed in less than 1 millisecond, and the body can adjust up to 60 times faster than a gas spring.
The suspension supports large height adjustment, 1,000 torque adjustments per second, and the four wheels are independently controlledMeet the needs of multi-scene driving, face complex road conditions, and walk on the ground.
NIO ET9 adopts a full-range 900V high-voltage architecture, with the highest voltage of 925V, peak charging power of 600kW, and peak charging current of 765AAnd it can be applied to 500V-1000V charging pile.
Equipped with NIO's self-developed 46105 large cylindrical battery cell, the energy density reaches 292Wh kgThe peak power of the new ET9 flash charge is as high as 600kW, which can charge 255 kilometers in 5 minutes, and it only takes 3 minutes to change the battery.
In terms of power, the NIO ET9 is equipped with a front 180 kW induction asynchronous motorThe weight is reduced to 69 kg, and the power density is 26kw kg, the industry's highest power density induction asynchronous electric drive;The rear is a 340 kW permanent magnet synchronous motor.
In addition,NIO's ET9 also pioneered seven safety redundancy standards for passenger cars, including drive, braking, steering, perception, computing, communication, and power distribution redundancy.
For example, its drive redundancy and dual electric drive system are 50 times more reliable than a single motorIn addition to the main braking system IPB, there is also a backup braking system RBU, which improves braking reliability by 513 timesSteering redundancy has a dual 12V power supply system, double the hardware of the steering motor, and the steering reliability is improved by 22 times.
In addition to the above active safety redundancy, in the body hardware passive safety redundancy,NIO ET9 also leaves enough room for redundancy, and additionally marks the identity of the security flagship on its administrative and technical flagship.
