The annual NIO Day is here again, and this time it finally came to Xi'an. NIO maintains that there will be major releases at every NIO Day, and this time NIO Day, NIO's new smart electric executive flagship ET9 was officially unveiled. The pre-sale of the NIO ET9 is 800,000 yuan**, and deliveries will begin in the first quarter of 2025. 
Mercedes-Benz S-Class, BMW 7 Series, Audi A8, Porsche Paramela, these top executive flagship models in the era of fuel vehicles have their own merits. In the era of intelligent electric vehicles, NIO ET9 wants to create a different executive flagship, which is different from the luxury of fuel vehicles.
Li Bin, Founder, Chairman and CEO of NIO, said at the press conference: "As the original intelligent electric executive flagship of the Chinese brand, the ET9 fully demonstrates the R&D strength and achievements of NIO, bringing the executive flagship sedan into the era of intelligent electric vehicles, and represents NIO's determination, confidence and enterprising spirit to continue to impact the high-end market. NIO will continue to provide users with high-quality products and services through technological innovation. ”
Super D-class space, chassis reaches a new dimension
If you want to become a luxury flagship, you can't avoid the luxury of body size, the NIO ET9 is 5325 mm long, 2016 mm wide, 1620 mm high, and has a wheelbase of 3250 mm. With the length of a D-segment sedan, this model achieves a higher level of space performance comparable to that of D-segment flagships such as the Mai**. The longitudinal space between the front and rear rows of the ET9 is as high as 2049mm, far exceeding that of the German long-axle D-class executive sedan.
The NIO ET9 inherits the design elements of the NIO family and goes one step further, adopting a flying body design, which combines the streamlined shape of a D-class sedan, the bird's-eye view of an SUV and the space experience of a super D-class flagship, like a pure electric business jet cruising close to the ground. Li Bin said in the interview that NIO's design gene is iterative rather than subversive, and NIO ET9 creates a more durable shape while inheriting NIO's design language.
As a luxury flagship model, the NIO ET9 adopts a native executive four-seat layout, equipped with NIO's self-developed second-row "flying first-class seats", which can achieve a wide range of backrest angle adjustment through seat cushion forward movement and seat-back linkage. The reclining seat can be seen as the admission ticket to the super D-class executive flagship, and the large range of forward and backward movement of the seat cushion makes it have high requirements for cabin space.
With the use of NIO Tianxing's intelligent chassis system, the car's handling stability has been improved to a new dimension. At the first of the press conference, a four-story champagne tower was placed on the front cover of the NIO ET9, driving on speed bumps, and the champagne glasses did not shake, and the call of the venue reached its peak.
The SKYRIDE intelligent chassis system has brought the magic carpet chassis to a new height, thanks to the world's first intelligent and highly integrated active suspension system, each shock absorber is highly integrated with independent electro-hydraulic pumps, and the brushless DC motor responds quickly, which can complete information processing, calculation and response within 1 millisecond. Each wheel (suspension) can be controlled individually, and the body can be raised or lowered in 2s, vFaster adjustment speed means you can cope with complex road conditions with ease.
In addition to the driving experience, NIO's fully active suspension can also make the body drop by 50mm instantly, so that users can enter the vehicle in the most natural posture without "squatting" or "climbing up" when getting into the car.
900V high-voltage platform, fast supercharging and faster battery change
The NIO ET9 will be the first vehicle to be equipped with a "global 900V high-voltage architecture", which includes core electronic and electrical components such as batteries, motors, wiring harnesses, air conditioners, DC-DC, and on-board chargers. The maximum voltage can reach 925V, the charging peak power is 600kW, and the charging peak current reaches 765A.
Technically, as the voltage increases, the current required to maintain a strong power output decreases, and the charging efficiency increases. 900V makes NIO's charging and swapping combination more efficient. It is the optimal solution for high-voltage electric vehicles, and based on NIO's "rechargeable, swappable and upgradeable" technology path, users can choose the most suitable and efficient energy replenishment method according to their own usage scenarios and convenience. "NIO has done a good job in battery swapping, but don't ignore that NIO Supercharging is also doing well. Li Bin said.
In addition, NIO ET9 will be equipped with self-developed 46105 large cylindrical cells and battery packs, which are most suitable for high-voltage fast-charging cells in terms of scale, safety, high energy density, and guaranteed performance.
900V high-voltage fast-charging large cylindrical batteries and battery packs have several advantages, such as:
Faster charging speed, achieving an efficient flash charging experience of 255km in 5 minutes;
Ultra-high energy density, the energy density of a single 5C cylindrical cell is as high as 292Wh kg
Ultra-low internal resistance loss, the industry's first single cell internal resistance, only 16 Hoou;
Higher safety, the electrical link and explosion-proof valve are separated at both ends of the battery cell to improve the safety of the single-cell battery
Higher space utilization, 24% increase in battery pack space utilization;
More stable temperature environment, the newly designed serpentine tube realizes double-sided cooling, and the heat dissipation efficiency is high.
The NIO ET9 also adopts a new generation of 900V high-performance electric drive platform, which adopts dual-motor redundancy to reduce power loss. Li Bin said at the press conference that NIO's use of dual motors is like the use of dual engines on airplanes. Not just for power, but for safety. This is also the reason why all NIO models use dual motors.
In addition, the rear permanent magnet synchronous motor in the 900V high-performance electric drive platform is the world's first 925V continuous wave winding motor, with a maximum speed of more than 20,000 rpm. The peak torque can reach 5000Nm, an increase of 16%, and the power density is 43kw/kg；Using the leading oil cooling process, the continuous capacity of high power output is increased by 30%, and the speed of 180km h can be continuously output for 30min.
In terms of charging and swapping, NIO officially released the first-class battery swap station and 640kW fully liquid-cooled ultra-fast charging pile. **The battery swap station supports multi-brand shared battery swapping, and the battery swap time is shortened by 22%.Equipped with a rooftop photovoltaic system. NIO's 640kW fully liquid-cooled ultra-fast charging pile has a maximum current of 765A, a maximum voltage of 1000V, and a peak charging power of 640kW, which can intelligently distribute charging power in the station in real time.
The background color of the executive flagship is the technical flagship
NIO ET9 will also continue to improve its intelligent driving capabilities, and the hardware will be equipped with a more powerful super-sensing system, Aquila20 Aquila, 31 high-performance perception hardware systems, including ultra-long-range lidar, dual-side wide-angle lidar and 4D imaging radar.
Ultra-long-range lidar, equipped with Wei's self-developed Yang Jian chip, such as tunnel backlit scenes, dark scenes at night, lidar imaging effect is better and clearer.
At the same time, the dual-side wide-angle lidar has built a 350° laser circumferential perception system for the first time, improving the perception of the side and rear, making the short-range and medium-range perception capabilities stronger, the detection ability of weak targets and small targets stronger, and the perception function of urban roads is more abundant.
4D imaging radar, more detailed horizontal resolution, point cloud density up to 2048point. It is not affected by extreme weather, such as heavy snow, and can cope with it freely, while significantly reducing false braking.
It is worth mentioning that NIO ET9 will be equipped with the first self-developed intelligent driving chip, Shenji NX9031, which is also the industry's first use of 5nm automotive technology with more than 50 billion transistors.
In terms of efficiency, "one core is stronger than four cores". Realize the close combination of computing power and its own algorithms, and the sharing of cross-domain computing resources for intelligent driving and cockpit.
NIO believes that its own intelligent driving chips and underlying software are all self-developed, which is convenient for timely upgrades, and based on computing power redundancy, it will be the top domain control in the next five years.
Technically, the NX9031 has a CPU computing group with super concurrent task processing capabilities and abundant memory access bandwidth to achieve fast and stable processing latency. And it's designed to deliver the industry's highest level of intrinsic security.
At the same time, NIO ET9** computing platform ADAM 20 is composed of 2 intelligent driving chips, Shenji NX intelligent cockpit chips. It can support the computing functions of six major sectors: intelligent driving, intelligent cockpit, intelligent chassis, body, power, and cloud domain.
It can be seen that in the era of smart electric vehicles, NIO has made the luxury of vehicles more diversified, not only in terms of ride luxury, but also in the technological luxury brought by computing power. As Li Bin said at the press conference, the administrative flagship must first be the technical flagship.
Li Bin said at the press conference: "Upward, in the face of the complexity of the world, we still adhere to the value of our hearts, enterprising, responsible, have requirements for ourselves, have enthusiasm for life, and are full of confidence in the future." ”
NIO's "upward" is also an upward trend in China's auto industry. At one time, the D-segment flagship sedan has been monopolized by European and Japanese brands. NIO's ET9 enters the luxury D-segment market with the concept of a technology flagship, which is not only an important release for NIO, but also a subversion of the luxury market by Chinese car companies.
