According to the company, two people involved in testing the electric car brand Nio died when one of them fell from a parking lot in Shanghai to the third floor.
The crash on Thursday was under investigation, but it was an accident and “not caused by the vehicle,” the company said in a statement.
The deceased employee is a “digital cabin tester,” one from Nio and the other from a partner.
The company said a vehicle had fallen from the third floor of the building next to the company’s Shanghai Innovation Port Building.
A photo of Chinese media showed a vehicle lying down with its roof depressed, surrounded by broken glass and rescuers.
