NIO Day 2023, held in Xi’an, was a pivotal moment for NIO and the EV industry, marking the debut of the NIO ET9. This smart electric executive flagship is tailored for the new generation of high-end business users, setting a new standard in the luxury EV market.
The ET9 showcases a sleek, contemporary design with a spacious interior, including the innovative “Sky Island” and “Executive Bridge”. The car’s dimensions are 5,325mm in length, 2,016mm in width, 1,620mm in height, and a 3,250mm wheelbase, offering ample cabin space and comfort. It features a four-seat layout with a 360-degree versatile tray table in the rear, 24 patented technologies for the first-class rear seats, and electric sunshades for added privacy.
Technologically, the ET9 is a marvel. It integrates over 100 NIO full-stack technologies, including 17 world-first and 52 leading technologies, supported by 525 patents. A highlight is the SkyRide Intelligent Chassis System, which is a combination of steer-by-wire, rear-wheel steering, and full active suspension. This system promises a smooth driving experience, akin to traveling on a flat surface.
NIO ET9 is equipped with China’s first Full-Domain 900V Architecture, boasting a peak voltage of 925V, a charging peak power of 600kW, and a charging peak current of 765A. This enables ultra-fast charging capabilities, with a 255km range extension possible with just a 5-minute charge. The ET9 also features a self-developed intelligent system with NIO’s super computing platform, Adam 2.0, supporting various computing functions. Additionally, it includes NIO’s first 5nm automotive-grade chip for autonomous driving, the NX9031.
Safety is paramount in the ET9, which boasts a torsional stiffness of 52,600Nm/deg and adheres to aviation-grade safety standards. It features redundancy in seven key systems, including driving, braking, sensing, computing, communication, and power distribution, setting a new safety benchmark for executive flagships.
