In truth of word, this was really a “challenge” between two personages: Giugiaro created two designs both splendidly enthralling albeit arduous to realize in series by Sabattini, whether owing to moldability (the Duino model with a downward sweeping zenith forming the base) or cut and bending techniques (the Icaro model with wing-shaped trimmed cornice). At the end of the day, the models achieved are truly suggestive and unsurpassed.
