General Motors is now putting to use a new 35,000-sq.-ft. “reduced scale” wind tunnel for aerodynamic tests using clay models that are up to 40% of the size of a normal vehicle. Why? Because such “reduced scale” testing improves the ability of engineers to decrease wind drag in a full-size vehicle design, GM noted. (Video courtesy of GM)
