A pre-production version of the Nio ET9 was initially revealed in China on December 23, 2023 at the 'Nio Day 2023' event at Xi'an's Olympic Sports Center, after which pre-orders for the ET9 opened.{{cite news|url=https://www.nio.com/news/nio-day-2023|title=NIO Day 2023 Held in Xi'an, Smart Electric Executive Flagship ET9 Unveiled|trans-title=2023蔚来日在西安举行 智能电动行政旗舰蔚来ET9正式亮相|website=NIO China|accessdate=2024-06-18}} At the 'Nio Day 2024' event held at Guangzhou on December 21, 2024, the production version of the ET9 was revealed with notable changes to its design, along with significantly more information about features and pricing. Deliveries of the ET9 are expected to begin in late March 2025, with a starting price of {{Currency|788,000|RMB}} ({{Currency|108,800|USD}}), or {{Currency|660,000|RMB}} ({{Currency|91,200|USD}}) and {{Currency|1,128|RMB}} ({{Currency|155|USD}}) monthly with a battery subscription plan.{{Cite web |last=Kang |first=Lei |date=2025-02-21 |title=Nio to start ET9 deliveries at end of Mar as CEO shares more detailed timeline |url=https://cnevpost.com/2025/02/21/nio-to-start-et9-deliveries-end-mar/ |access-date=2025-03-02 |website=CnEVPost |language=en-US}}

The ET9 is an F-segment four-seater full-size luxury liftback sedan with a length of {{Convert|5325|mm|in}} and a wheelbase of {{Convert|3250.|mm|in}}, which is close to the {{Convert|3300.|mm|in|adj=on}} maximum wheelbase that third generation Nio battery swap stations can accommodate, and is too long to be compatible with first and second generation stations. It is the second vehicle to be built on the NT 3.0 platform after the Onvo L60, and uses fully 900{{Nbsp}}V powertrain components, the first to do so in China.

A limited edition of the ET9 called the First Edition became available for pre-order after the Nio Day 2024 event on December 21, 2024, and all 999 units were sold within 12 hours. It features unique logos placed throughout the vehicle, and comes standard with normally optional features such as 23-inch wheels.{{Cite web |last=Zhang |first=Phate |date=2024-12-22 |title=Nio says ET9 orders exceeded expectations, 999 limited edition units sold out |url=https://cnevpost.com/2024/12/22/nio-et9-999-limited-edition-units-sold-out/ |access-date=2025-03-02 |website=CnEVPost |language=en-US}}{{Cite web |last=Opletal |first=Jiri |date=2024-12-22 |title=Nio ET9, priced at 112,000 USD, sold out 999 units hours after the launch |url=https://carnewschina.com/2024/12/22/nio-et9-priced-at-112000-usd-sold-out-999-units-hours-after-the-launch/ |access-date=2025-03-02 |website=CarNewsChina.com |language=en-US}} After continued demand for special editions, Nio launched the ET9 Signature Edition several days later on December 26.

It features a SkyRide fully active suspension.{{cite news |url=https://www.businessinsider.com/nio-et9-ev-china-skyride-intelligent-chassis-snow-video-2024-2 |title=This Chinese EV can shake off snow like a puppy |first=Nora |last=Naughton |work=Business Insider |location=US |date=2024-02-21 |access-date=2024-04-20}}

The ET9 has the first implementation of Nio's self-developed 5 nm Shenji NX9031 autonomous driving chip. According to Nio, each of the ET9's two Shenji chips has higher computational ability than the previous 1016{{Nbsp}}TOP Adam system, which consists of four Nvidia Orin-X chips. It has a total of 31 sensors in its autonomous driving sensor suite called Aquila 2.0, including 360-degree camera coverage.{{Cite web |last=Bobylev |first=Denis |date=2024-12-21 |title=Nio Day 2024 live updates: Firefly EV, Nio ET9 and more |url=https://carnewschina.com/2024/12/21/nio-day-2024-live-updates-firefly-ev-nio-et9-and-more/ |access-date=2024-12-21 |website=CarNewsChina.com |language=en-US}} The ET9 features Nio's first use of 4-dimension mmWave radars, which are capable of measuring elevation in addition to azimuth, range, and velocity like conventional 3-dimension radars.{{cite arXiv |eprint=2306.04242 |last1=Han |first1=Zeyu |last2=Wang |first2=Jiahao |last3=Xu |first3=Zikun |last4=Yang |first4=Shuocheng |last5=He |first5=Lei |last6=Xu |first6=Shaobing |last7=Wang |first7=Jianqiang |last8=Li |first8=Keqiang |title=4D Millimeter-Wave Radar in Autonomous Driving: A Survey |date=2023 |class=eess.SP }} It has two side-facing LiDAR units mounted on the front fenders, which have a range of up to {{Convert|150|m|ft}}, along with a front-facing roof mounted unit which allows for 350-degree LiDAR coverage.

The Nio ET9's SkyRide intelligent chassis system incorporates a hydraulic fully active suspension developed by U.S.-based company ClearMotion.{{cite press release |title=ClearMotion Secures Landmark Production Order from NIO for Proactive Suspension Technology |url=https://www.prweb.com/releases/clearmotion-secures-landmark-production-order-from-nio-for-proactive-suspension-technology-302021556.html |publisher=PRWeb |date=December 23, 2023 |access-date=April 23, 2025}} This system, known as ClearMotion1, utilizes electro-hydraulic actuators at each wheel to adapt to road conditions in real time, enhancing ride comfort and stability. ClearMotion1 can reduce in-cabin motion by approximately 75% compared to existing technologies, responding to road inputs within milliseconds. At the ET9's launch, Nio demonstrated the suspension's capabilities by driving over speed bumps with a tower of champagne glasses on the hood, none of which spilled. In December 2023, ClearMotion announced a production order from Nio for three million units of its ClearMotion1 suspension system, marking the ET9 as the first model to feature this technology. Deliveries of the ET9 with Active Suspension began in the first quarter of 2025.{{cite news |last=Carey |first=Nick |title=ClearMotion to supply smooth suspension tech for Nio's ET9 EV |url=https://www.reuters.com/business/autos-transportation/clearmotion-supply-smooth-suspension-tech-nios-et9-ev-2023-12-23/ |work=Reuters |date=December 23, 2023 |access-date=April 23, 2025}}{{cite news |last=Smith |first=Bill |title=NIO ET9 Ultra Luxury EV Sedan Comes Equipped with SkyRide Intelligent Chassis, Easily Tackles 5-Layer Champagne Tower |url=https://www.techeblog.com/nio-et9-skyride-champagne-tower/ |work=TechEBlog |date=December 21, 2024 |access-date=April 23, 2025}}

The ET9 is the first vehicle to use Nio's Thunder EDS (electric drive system), which is the first in China to use a mass produced global 900{{Nbsp}}V electrical architecture, which includes the traction motors, battery, drive power supply electronics, and HVAC system.{{Cite web |title=NIO's executive flagship sedan model ET9 hits market, delivery to begin in March 2025 |url=https://autonews.gasgoo.com/new_energy/70035484.html |access-date=2024-12-21 |website=Gasgoo}} The single powertrain option is a dual-motor all-wheel drive system with a total output of {{Convert|697|hp|kW PS|abbr=unit}} and {{Convert|700|Nm|lbft|abbr=unit}} of torque. It uses a 79 kg permanent magnet synchronous motor with W-pin (continuous wave) windings for higher efficiency and smaller dimensions, and runs at 925V to output {{Convert|340|kW|hp PS|abbr=unit}} to the rear wheels, for a power density of 4.3 kW/kg. It also has a {{Convert|180|kW|hp PS|abbr=unit}} AC induction motor powering the front wheels, with a power density of 2.6 kW/kg, which Nio claims is the world's highest for the motor type.{{Cite web |last=Bobylev |first=Denis |date=2024-03-27 |title=Nio rolls out world's first mass-produced 900V drive system |url=https://carnewschina.com/2024/03/27/nio-manufactured-worlds-first-mass-produced-900v-drive-system/ |access-date=2024-12-21 |website=CarNewsChina.com |language=en-US}} Power is fed to the motors through a 1200V silicon carbide inverter with a power density of 1315 kW/L.

The ET9 is powered by a swappable 100{{Nbsp}}kWh battery with an energy density of 292{{Nbsp}}Wh/kg using Nio's self-developed 46105 cylindrical format battery cells. The high pack voltage allows for the battery to be charged by 500{{En dash}}1000{{Nbsp}}V DC fast chargers at a peak power of 600{{Nbsp}}kW and a peak current of 772{{Nbsp}}A, allowing for 5C charging rates. The battery can be swapped at a fourth generation Nio swap station in 144 seconds, and provides a CLTC range rating of {{Convert|650|km|mi}}.
