 Under the direction of Giorgio <unk> , Maserati began development of an FIA GT @-@ eligible race car . This car , which would eventually be named the MC12 , was initially called the " MCC " ( " Maserati Corse Competizione " ) and it was to be developed simultaneously with a road @-@ going version , the " MCS " ( " Maserati Corse <unk> " ) . Frank Stephenson did the majority of the body styling , but the initial shape was developed during wind tunnel testing from an idea had by <unk> Giugiaro . The MCC has a very similar body shape to the MC12 , but there are several key differences , most notably the rear spoiler . Andrea Bertolini served as the chief test driver throughout development , although some testing was done by Michael Schumacher , who frequently tested the MCC at the Fiorano Circuit . During the development process , the MCC name was set aside after Maserati established the car 's official name , MC12 .
