The Nio ET7 is a battery electric full-size luxury sedan produced by Chinese electric car company Nio. It is the world's first production car to be compatible with a mass-produced semi-solid state battery pack, which can be equipped at a battery swap station. The ET7 is the first Nio vehicle to come equipped with LiDAR, and is currently serving as Nio's flagship model before the ET9 begins deliveries in early 2025.
Overview
[edit]Nio ET Preview concept
[edit]The Nio ET Preview concept electric sedan was revealed at Auto Shanghai in April 2019. It exhibited Nio's upcoming ET series of sedans, and more specifically, the ET7.[1] It is equipped with a Level 4 autonomous driving system, and is compatible with Nio Power charging solutions, including battery swap stations, mobile charging vans, and charging station network.[2] It is equipped with dual-motor all-wheel drive and has a driving range of over 400 kilometres (250 mi). The production ET7 retains many of the design cues and overall shape featured in the concept.

Production model
[edit]
The Nio ET7 was unveiled in China on 9 January 2021 at the 'Nio Day' event in Chengdu, retaining many design cues of the 2019 Nio ET Preview concept car. It went on sale on March 28, 2022 in China, and it serves as a direct competitor to the Tesla Model S sedan in that market.[3][4] In late 2021, Nio announced by Nio that ET7 will be sold in Germany in late 2022.[5] The first European deliveries of the ET7 occurred in October 2022 in Germany and the Netherlands, with units for Denmark and Sweden arriving in November. It is produced under a contract manufacturing agreement with JAC Motors.[6] On the 26th April 2022, Nio's 200,000th car was produced and it was an ET7.[7]
The interior of the ET7 features the NOMI animatronic AI assistant mounted on top of the dashboard, a 260 mm (10.2 in) electronic instrument cluster display, a 330 mm (12.8 in) centre touchscreen infotainment system, and a 23-speaker audio system with a 1000-watt output. The ET7 comes with third-generation Qualcomm® Snapdragon™ Automotive Cockpit Platform for in-car mobile connectivity and communication including 5G, NFC and Bluetooth 5.2. The ET7 will be first production car to feature Karuun, a sustainable rattan material. The ET7 also features 256 colour interior ambient lighting, soft close doors with frameless windows, and intelligent fragrance system.[8]
2024 refresh
[edit]On April 16, 2024, pre-orders opened for the 2024 ET7 with a deposit of CN¥ 5,000 (approximately US$690).[9] On April 25, the refreshed Nio ET7 was officially launched at the 2024 Beijing International Automobile Exhibition, with deliveries beginning on April 30. Pricing remained similar to previous years in spite of increased competition and a pricing war in the industry; models equipped with the 100 kWh battery saw a CN¥ 10,000 (approximately US$1,400) price increase.[10]
Exterior changes are minimal, with a new silver paint color and new 21-inch wheel options and all dimensions remaining the same. Most changes were made to the interior, especially in the second row where the new ET7 now uses aviation-style executive seats based on Nio’s self-developed seat frame. They feature a total of 14-way electric adjustment including headrest, front and rear movement, backrest angle, seat cushion angle and other adjustments.[11] There are also two 14.5-inch 3K OLED entertainment displays mounted to the front seatbacks for use by rear passengers. A new sound system has a peak power of 2230 W, and there are more soft touch materials throughout the cabin.[12]
The ET7's computing systems have also been upgraded, with it now consisting of a Qualcomm Snapdragon 8295 SoC accompanied with four Nvidia Orin X chips, called ADAM. Nio claims a twofold increase in CPU performance, triple GPU performance, and eight times increase in NPU performance. The NOMI AI assistant has been updated to use GPT models that are run locally, without the need for an internet connection, increasing data privacy.[13]
The powertrain remains unchanged, with the option of 75, 100 or 150 kWh LFP batteries, with the latter featuring a semi-solid state electrolyte and is only available in the battery as a service (BaaS) subscription model; power output remains at 480 kW; 653 PS (644 hp).
Specifications
[edit]The Nio ET7 comes available with three battery options: a 70-75 kWh battery (NEDC range of 500–550 km (311–342 mi)), a 100 kWh battery (NEDC range of 700 km (435 mi)), and eventually a 150 kWh Ultra High Range semi solid-state battery (NEDC range of 1,000 km (621 mi)), which has an energy density of 360Wh/kg. The 100 kWh battery weighs 656kg while the 150 kWh battery weighs only 20kg more.
The ET7 has two electric motors, one in the front and one in the rear of the car, which produce a combined output of 480 kW; 653 PS (644 hp) and 850 N⋅m (630 lb⋅ft). The 0 to 100 km/h (0 to 62 mph) acceleration is 3.8 seconds, the braking distance from 100 to 0 km/h (62 to 0 mph) is 33.5 m (109.9 ft), and the drag coefficient is 0.208.[14]

Autonomous driving system
[edit]The autonomous driving system in the Nio ET7 is called Aquila, which uses 33 sensors, including seven 8 MP high-definition cameras, four 3 MP light-sensitive surround-view cameras, a high-resolution LIDAR with a 500 m (1,640.4 ft) range, 5 millimeter-wave radars, 12 ultrasonic radars, and 2 high-precision positioning units. The Aquila autonomous driving system generates 8 gigabytes of data per second which is analysed by an onboard computer called Adam.[15]
Aerodynamics
[edit]The aerodynamics of the Nio ET7 was one of the primary focus areas during the development of the vehicle. Extreme work and effort was dedicated to making sure that the car achieved an extremely low aerodynamics drag coefficient in order to enhance the vehicle's driving range and performance. On September 20, 2021[16] the Nio ET7 was tested at CAERI Wind tunnel Testing Centre in Chongqing, China and achieved a certified drag coefficient of 0.208.[17][18]
Awards
[edit]In 2022, the ET7 received the Golden Steering Wheel award in the Medium and Upper Class category.[19] It was given the Car of the Year 2022 award by the Swedish magazine auto motor und sport Sverige, and also won in the luxury class.[20] A 2023 75 kWh model received a 'B' rating from the China Consumer Research and Testing Center.[21]
