NIO unveils ET9 smart electric executive flagship; 900V architecture

At NIO Day 2023, NIO unveiled the ET9, a smart electric executive flagship. With a length of 5,325mm, a width of 2,016mm, a height of 1,620mm, and a wheelbase of 3,250mm, NIO ET9 presents a strong stance. Adopting the Landjet design, it offers users cabin space, comfort, safety, and responsive steering.


NIO ET9 brings together more than 100 NIO full-stack technologies, including 17 world-first technologies, 52 leading technologies, and 525 patents filed.

The SkyRide Intelligent Chassis System of NIO ET9 integrates three core hardware systems—steer-by-wire, rear-wheel steering, and full active suspension—for the first time. In the face of complex road conditions, NIO ET9 can deliver a driving experience akin to traveling on a flat surface.


A 340 kW permanent magnet motor with SiC at the rear and a 180 kW induction motor at the front generate a total power of 520 kW.

NIO ET9 is equipped with China’s first Full-Domain 900V Architecture, featuring the highest voltage of 925V, a charging peak power of 600kW, and a charging peak current of 765A. The 900V ultra-fast charging and swapping platform allows fast recharging after a 3-minute battery swap or extending the range by 255km with a 5-minute charge.

NIO ET9 features a self-developed intelligent system, where NIO’s super computing platform Adam 2.0 supports computing functions in six major areas: intelligent driving, digital cockpit, intelligent chassis, body, e-powertrain, and cloud.

NIO premiered its first 5nm automotive-grade chip for AD, the NX9031, achieving a strong combination of computing power and proprietary algorithms. It shares computing resources between autonomous driving and cockpit domains, delivering safety and efficiency.

SkyOS, NIO’s vehicle operating system, creates a technical cluster covering vehicle control, intelligent driving, cockpit, and mobile connectivity, constituting the “soul” of the executive flagship.

NIO ET9 incorporates flagship-level safety features covering every aspect of travel safety. Not only does it possess a torsional stiffness of 52,600N·m/deg, but it also expands safety boundaries with the most advanced sensing units and computing capabilities.

Designed following aviation-grade safety standards, NIO ET9 allows for safety redundancy in seven key systems of smart EV, including driving, braking, sensing, computing, communication, and power distribution, setting the global safety benchmark for executive flagships.

NIO ET9 is available for pre-order in China, with delivery time scheduled in the first quarter of 2025.
