More than 40 years ago the General Motors wind tunnel began testing the aerodynamics of all its vehicles. For this purpose, a large full-scale wind tunnel was built. At the heart of this wind tunnel is the massive turbine wheel with 5 blades turning at high speed. Each blade is more than 220 inches long and is crafted to be relatively lightweight. However, due to the size of the blade, they still weigh about 1 ton each.
