The aim of this work is to indicate a methodology of “design for aesthetics”, through the realization of a particular city-car body. We had to realize a good looking car, without forgetting the importance of mechanical and economical aspects. The result we have got is very interesting, in fact the city-car obtained is a sum of beauty, economics and intelligence. The method followed is very similar to those methods used by the most famous firms of design products, just like Pininfarina, Giugiaro Design, Bertone, etc.. This method is illustrated in the paragraphs below.
