The Wind Tunnel Center of China Automotive Engineering Research Institute tests over 200 vehicle models every year.

At the Wind Tunnel Center of the China Automotive Engineering Research Institute, more than 200 vehicle models can be tested each year. Wind tunnel testing is a key process in the research and development of new energy vehicles. By simulating the driving environment of vehicles, observing the aerodynamic performance of vehicles, and obtaining important data such as drag and wind noise, vehicle body shape can be further optimized, energy consumption can be reduced, and performance can be adjusted. For every 0.01 decrease in the drag coefficient obtained from testing, the driving range of a pure electric vehicle can be increased by approximately 8 kilometers. The Wind Tunnel Center is also equipped with microphone arrays, visualization systems, and high-precision algorithm models, which can accurately measure the drag of new energy vehicles and evaluate wind noise performance, leading to a technological shift from "listening for noise with ears" to "seeing noise with eyes".
