Interior

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 was on sale on March 28 in 2022 in China.[1] It acts as a direct competitor to the Tesla Model S sedan in China.[2] It has been announced by Nio that ET7 will be sold in Germany later in 2022.[3] On the 26th April 2022, Nio's 200,000th car was produced and it was an ET7.[4]

The interior of the ET7 features NOMI AI assistant on the dashboard, an 260 mm (10.2 in)  electronic instrument cluster, a 330 mm (12.8 in) centre touchscreen, and a 23-speaker audio system with a 1000-watt output. ET7 comes with third-generation Qualcomm® Snapdragon™ Automotive Cockpit Platform for in-car mobile connectivity and communication including 5G, NFC and Bluetooth 5.2. ET7 will be first production car to feature Karuun®, a sustainable rattan material. ET7 also features, NOMI AI personal assistant, 256 colours of interior ambient lighting, soft close doors, and intelligent fragrance system.[5]

On April 25, The Nio ET7 Executive Edition was officially launched at the 2024 (18th) Beijing International Automobile Exhibition. The ET7 Executive Edition uses aviation executive seats based on Nio’s self-developed seat frame. Among them, the rear row adopts the design of aviation executive seats, which supports a total of 14-way electric adjustment including headrest, front and rear, backrest, seat cushion and other parts.[6]

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 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.[7]

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.[8]

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[9] the Nio ET7 was tested at CAERI Wind tunnel Testing Centre in Chongqing, China and achieved a certified drag coefficient of 0.208.[10][11]

Nio ET Preview

edit

The Nio ET Preview concept electric sedan was revealed at Auto Shanghai in April 2019. It previews Nio's ET series of sedans, and more specifically, the production ET7.[12] The ET7 retains many of the design cues and overall shape featured in the concept.
