In July and August, the Nio ET7 completed winter testing and summer testing, respectively.

After concluding the highland testing, Nio will also continue to conduct urban road testing around the world to ensure that the ET7 delivers an experience that exceeds expectations when it is delivered, the company said.

In July, Nio conducted a month of winter testing of the ET7 at the SHPG International Test Track in New Zealand. The test track is a well-known winter test track in the southern hemisphere, open only from June to August each year, where many car brands conduct tests.

In August, Nio completed the ET7's summer heat test in Sanya, the southernmost city in China's Hainan Province.

Nio unveiled the flagship sedan at Nio Day 2020 on Jan. 9, and it continues the high-performance character of the company's models.

The ET7 is powered by a 180 kW permanent magnet motor and a 300 kW induction motor with a maximum power of 480 kW.

It has a peak torque of 850 Nm and accelerates from 0-100 100 km in just 3.9 seconds.

The pre-subsidy price of Nio ET7 is RMB 448,000 ($70,100) - 526,000. If users choose Nio's battery rental solution BaaS, the pre-subsidy price drops to RMB 378,000-398,000 with a monthly battery rental of RMB 980- 1,480.
