Overview

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 will be launched in early 2022 with a starting price of ¥448.000 (~$69,200 USD). It acts as a direct competitor to Tesla's Model S sedan in China.[1]

The interior of the ET7 features an AI assistant on the dashboard, an electronic instrument cluster, a large center touchscreen, and a 23-speaker audio system with a 100-watt output.

Battery specifications

The NIO ET7 comes available with three battery options: a 70 kWh battery (NEDC range of 500 km), a 100 kWh battery (NEDC range of 700 km), and a 150 kWh solid-state battery (NEDC range of 1000 km), which has an energy density of 360Wh/kg.

The ET7 has two electric motors, one in the front and rear of the car, which produce a combined output of 644 hp and 850 Nm. The 0 to 100 km acceleration is 3.9 seconds, the braking distance from 100 to 0 km is 33.5 m (109.9 ft), and the drag coefficient is 0.23 Cd.[2]

Autonomous driving system

The autonomous driving system in the NIO ET7 is called Aquila, which uses 33 sensors, including 11 8-megapixel high-definition cameras and a long-distance high-definition camera, 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 analyzed by an onboard computer called Adam.[3]

NIO ET Preview

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.[4] The ET7 retains many of the design cues and overall shape featured in the concept.
