In 1953, his big break came when Maserati decided to offer three young drivers the chance to drive their sportscars; Emilio was chosen along with Luigi Musso and Sergio Mantovani.

It was with the Officine Alfieri Maserati squad, when he scored his biggest win, when he took a class victory on the 1953 Mille Miglia.

[2][3] During this period, he enjoyed some success, scoring his only race win, in the 1952 non-championship Trofeo della Reggione Sardo and finished on the podium in the 1953 Targa Florio.

He was also originally listed to race in the 1954 Gran Premio de la Republica Argentina, but Maserati gave the drive to Musso instead.

[8] Despite his passion for speed, he abandoned motorsport when he inherited the family business, Giletti S.p.A., one of the leading companies in the production of yarns.
