On the evening of December 23, 2023, NIO DAY unveiled the long-established new car ET9, which is positioned as a carExecutive flagship sedan, technology flagship sedan。This is an executive flagship that is comparable to the Mai** S-Class, BMW 7 Series and Porsche Paramela, and is an executive technology flagship that represents the world's top intelligent technology. The ET9 will be priced at RMB 800,000 and will be mass-produced and delivered in the first quarter of 2025.
AppearanceET9 adopts the design language of "flying body", which looks more slender, more atmospheric, calm and unassuming, and still maintains the family's sense of fashion. The car is equipped with intelligent high-definition projection headlights, which can project zebra crossings for pedestrians and present a "trailing light carpet" effect when turning. The front face as a whole still maintains the style and temperament of the ET7 family, but it is more detailed, more refined and sharper than the ET7.
The 23-inch aluminum alloy forged high-gloss color-block wheels are designed with a self-suspended wheel logo and a 790mm tire diameter that is the largest in the same class. For the first time, the new car also added side-facing wide-angle lidar based on the iconic watchtower lidar and camera.
At the rear, the electric rear wing deploys automatically at speeds above 80 km/h, improving aerodynamics and range.
Body sizeThe overall shape of the ET9 is close to the combination of a sedan and a crossover, with a length, width and height of 5324 2016 1620mm and a wheelbase of 3250mm. 
InteriorThe roof also has a longitudinal "Sky Island" with arched ambient lighting and a separate canopy, as well as 7 electric sunshades. The car has a longitudinal "administrative bridge" design, and the "Sky Island" and "Administrative Bridge" complement each other to build four exclusive first-class immersive experiences. 
In the front row of the vehicle, behind the main and co-driver, each provided a piece of 145-inch OLED connected executive display with adjustable tilt angle.
ET9 is the first to create a native four-seat layout for the executive flagship, running through the front and rear rows, and is claimed to integrate 20 subsystems. There is also a 360° infinitely adjustable executive table in the rear area. 
The integrated electric opening and closing refrigerator supports electric opening at the touch of a button, has a space of about 10 liters, and supports temperature adjustment between -2 and 55.
In terms of power, the front motor of the maximum power of 180kw induction asynchronous machine, weight reduced to 69 kg, power density 26kw kg, the industry's highest power density induction asynchronous electric drive;The maximum power of the rear motor is 340kw. The new car is equipped with a full-range 900V high-voltage architecture, including core components such as batteries, motors, DC-DC, and on-board chargers, with a maximum voltage of 925V, a peak charging power of 600 kW, and a peak charging current of 765A.
NIO ET9 also has a built-in 5C high-voltage fast-charging battery pack with a capacity of 120kWh, using self-developed 46105 large cylindrical cells with an energy density of 292Wh per cellIt supports 5C flash charging, and with the 640kWh charging pile, it is claimed to be able to achieve a range of 255 kilometers in 5 minutes.
Intelligent drivingET9 is the crystallization of NIO's full-stack technology layout and world-leading technology, including 17 world-premier technologies, 52 class-leading technologies, and 525 patents, defining a new standard for intelligent electric administrative flagships with innovative technology.
ET9 provides 3 lidars to form a 360° detection capability without dead ends, and ET9 is first equipped with a self-developed intelligent driving chip "Shenji NX9031", which is built with 5nm vehicle specification process, and the car has a built-in ** supercomputing platform 20 Support the computing functions of 6 major sectors, including intelligent driving, intelligent cockpit, intelligent chassis, body, power, and cloud domain. Built-in Aquila 20 The "Skyhawk" Super Sensing System, which claims to have a sensing range equivalent to 60 football fields. Chassis aspectNIO's ET9's "Skyride Intelligent Chassis System" integrates the three core hardware systems of steer-by-wire, rear-wheel steering, and fully active suspension for the first time, and is currently the world's only fully drive-by-wire intelligent chassis. Because it is data-driven, the full drive-by-wire intelligent chassis has the ability to evolve, iterate and grow. The fully wire-controlled intelligent chassis and VMC intelligent computing platform support the positioning of ET9 as an administrative flagship and technical flagship.
NIO has achieved its goal of adding 1,000 new battery swap stations in 2023 ahead of schedule, and will continue to add 1,000 new battery swap stations and 20,000 charging poles in 2024. At the press conference, NIOAt the same time, the first-class battery swap station and 640kW fully liquid-cooled ultra-fast charging pile were released.
NIO's new flagship ET9, as a high-end model of NIO, focuses on administrative flagship and technology flagship. It is a masterpiece of NIO's current technology and quality.
ET9 has created a technology complex that integrates mobile administrative space, mobile office, and exclusive business meeting room.
It is hoped that the NIO ET9, as the first administrative flagship and technology flagship model of domestic new energy, will be able to sell well and meet the expected experience of consumers.
