In the spring of 1961, Count Giovanni Volpi di Misurata's Scuderia Serenissima bought two specimens of the Type 63 which on April 30 made its debut at the Targa Florio. The engine of the first configuration of the Tipo 63 Serenissima was the 2890cc 4-cylinder, which was later replaced with the 3000cc V12 that had been tested in 1957 on the Formula 1 250F T2. Unfortunately, overall, the Tipo 63 was an unbalanced car. , far from the road holding and handling qualities of the Tipo 61. At the beginning of 1962 the Tipo 63 was transformed into the Tipo 64, with several upgrades to the chassis, body and engine.
