They allow a number of advantages. One can find several common points with aeronautic construction. There are also disadvantages that are more specific to automobiles.  Advantages include  Lightening of the vehicles: A reduction of mass of 1 kg induces a final reduction of 1.5 kg, taking into account the consecutive lightening of the mechanical components.
