A new energy vehicle quietly enters a testing area at Nio's advanced manufacturing plant in Hefei, Anhui province. Its doors open and close, seats adjust, lights switch on and sensors activate — all without human operation.

Within minutes, the vehicle completes a full "health check" before leaving the factory.

The scene at Nio's advanced manufacturing Xinqiao No 2 plant reflects a broader transformation taking place in China's manufacturing sector, where artificial intelligence and industrial data are reshaping production processes.

"Nio's 'Tiantan' AI-powered vehicle self-inspection system can use the vehicle's own hardware and software capabilities to complete more than 1,000 functional inspections within three minutes, without external equipment or manual intervention," said Zhang Sen, head of the Tiantan project at Nio's manufacturing quality department.
