GM Cuts Vehicle Design Testing from Weeks to Minutes with AI Wind Tunnel

General Motors has deployed an AI virtual wind tunnel that evaluates how aerodynamic drag affects vehicles in near real-time, replacing weeks of physical prototype testing. Designers can now test drag properties early in the design phase rather than after prototypes are built. The system compresses a major bottleneck in vehicle development and lets engineers explore design variations that were previously too costly or time-consuming to test.
