The Nio ET7 is a battery electric full-size luxury sedan produced by Chinese electric car company Nio. 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

Nio ET Preview concept

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 250miles. The production ET7 retains many of the design cues and overall shape featured in the concept.

Production model

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  electronic instrument cluster display, a 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

On April 16, 2024, pre-orders opened for the 2024 ET7 with a deposit of (approximately).[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 100kWh battery saw a (approximately) 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 2230W, 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 150kWh 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 .

Specifications

In every configuration, the ET7 has electric motors on each axle in a dual-motor all-wheel-drive setup. The front axle is powered by a permanent magnet synchronous AC motor making 180kW and 350Nm of torque. The rear is powered by an induction AC motor which produces 300kW and 500Nm of torque. The combined output is 480kW and 850Nm of torque. The 0to acceleration time is 3.8 seconds, the top speed is 200km/h, the braking distance from 100to is 33.51NaN1, and the drag coefficient is 0.208.[14] The 75kWh model's weight starts at 2359kg (5,201lb), and all models have a 49.5:50.5 weight distribution and a gross vehicle weight rating of 2900kg (6,400lb).

Battery packs

The Nio ET7 is sold with two purchasable battery options, a standard range pack and long range pack. Initially, the standard range pack was to be a 70kWh NMC battery produced by CATL, with 500km (300miles) of CLTC range. Later, it was replaced by a new 75kWh LFP-NMC dual chemistry battery with peak range of 550km (340miles) revealed before ET7 production began. It consists of an undisclosed ratio of serially connected LFP and NMC battery cells assembled in a cell-to-pack format and a special pack management system, and it allows for a blend of each chemistries advantages: the higher energy density, better cold weather charging, and accurate state-of-charge readings from NMC cells, and the lower costs, lower wear, and improved safety from LFP cells. For the 2024 facelift, the standard range battery was once again changed, this time to a fully LFP cell-to-pack battery pack which also features an increased peak DC fast charging rate of 170kW compared to the previous pack's 140kW rate.[15] [16]

The long range battery is a 100kWh NMC pack sourced from either CATL or CALB, with a cell-to-pack design and allows for up to 7050NaN0 of range.

In mid-2024, a 150kWh semi-solid state NMC battery was introduced, allowing for an NEDC range of 10500NaN0. It is the first ever mass produced automotive traction battery to use semi-solid state electrolyte technology, and is supplied by WeLion.[17] The semi-solid state technology allows it to have a 50% higher capacity with only a 20kg (40lb) weight increase over the 555kg (1,224lb) 100kWh pack, while maintaining the same size. It is initially available only as a short-term rental from a battery swap station, but it is planned to be available for purchase later. At the announcement in February 2024, Nio said that each pack costs the company as much as an entire ET5 at launch, which has a starting price of, or (approximately, or) with a battery subscription.[18] [19] [20]

Autonomous driving system

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 5001NaN1 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.[21]

Aerodynamics

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 the Nio ET7 was tested at CAERI Wind tunnel Testing Centre in Chongqing, China and achieved a certified drag coefficient of 0.208.[22]

Awards

In 2022, the ET7 received the Golden Steering Wheel award in the Medium and Upper Class category.[23] 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.[24] A 2023 75kWh model received a 'B' rating from the China Consumer Research and Testing Center.[25]
