A Chinese internet user recently posted a spy photo of what appears to be an Nio (NYSE: NIO) sedan, the EE7, which shows that the car is not very tall and is the size of a sedan.

The car uses multiple camouflages, so it is speculated that the car may be Nio's sedan that will be unveiled at 2020 Nio Day.

Nio had unveiled the ET Preview concept at the 2019 Shanghai Auto Show, and at Nio's Q2 2020 quarterly meeting, Nio revealed that the next product is set to be a sedan.

Although specific data was not released, Nio said at the time that new technology would be available.

The production model of the concept car may be named Nio EE7 and will be unveiled at Nio Day in Chengdu, according to current information.

According to previous information, the car, the first flagship sedan of Nio, will be built on the second-generation NP2 platform currently under development. It is likely to go on sale in 2022 and will probably feature an L4 level driver assistance system.

Earlier this month, Nio said that its next Nio Day event will be held in Chengdu on January 9, 2021.

Nio Day is Nio's annual owners' gathering, and the company didn't disclose details of the event, but it is expected to unveil the Nio EE7 flagship sedan.

Nio Day 2020 will be held at Wuliangye's Chengdu Financial City Performing Arts Center, and Nio said that this year will be a special edition of Nio Day for New Year's Eve, taking into account the venue schedule and other factors.
