In addition, the Changsha R&D Center also has a testing site and vehicle equipment room located in the intelligent system testing area of the Xiangjiang New Area, approximately 3 kilometers away from the company. This testing area is currently the longest and most complex closed intelligent system testing area for different scenarios in China. Here, the Changsha R&D Center can use different scenarios in the testing area for vehicle calibration, stability testing, and autonomous driving testing.
