• The wind tunnel is an essential facility in the development of new models
• The tunnel is used to test aerodynamics, which is essential in making cars safer, more comfortable, and which also consume less
• Tests are performed on the latest configuration of the new CUPRA Leon Competición to achieve less drag

Nobody can see it, but it is a factor in a car's fuel consumption, safety and comfort. It's called aerodynamics, or the study of how air moves around solid objects. In the automotive world, its application is very practical: reducing a car's resistance to wind. And all this is tested in its temple, the wind tunnel. This is how it works.
