Chinese electric car marker Nio says two text drivers were killed in a crash which took place when a test car plunged several stories to the ground.
The incident took place on Wednesday. The people that died were inside the vehicle as it fell from the third storey of the building.
Nio says it immediately started an investigation into the incident in co-operation with government officials.
A preliminary investigation suggested the crash was an accident and had nothing to do with the vehicle itself, Nio said in a statement on Weibo, a Chinese microblogging site, about four hours after the incident.
