A look inside GM's scaled-down wind tunnel

Nov. 17, 2015

General Motors is using a new $30 million 35,000 sq. ft. “reduced scale” wind tunnel to improve the aerodynamic shapes of its vehicles, cars and trucks alike. By using clay models that are up to 40% of the size of a normal vehicle, GM’s engineers better decrease wind drag when they reach full-size vehicle design stage. (All photos courtesy of GM)
