Ferrari has announced that it has added Mirko Bortolotti, Daniel Zampieri and Raffaele Marciello to its Ferrari Driver Academy project, alongside first recruit Jules Bianchi.
Bortolotti and Zampieri have already tested for Ferrari as their prize for winning the Italian Formula 3 title in 2008 and 2009 respectively.
Having raced in Formula 2 last year, Bortolotti is set for a GP3 seat with Addax in 2010, while Zampieri will drive for Pons in Formula Renault 3.5.
Marciello, a 15-year-old karting graduate, will be placed in Italian single-seater category Formula Abarth (formerly Formula Azzurra) this year.
Ferrari has also revealed that the champion in new Brazilian series Formula Future Fiat will automatically become part of its Academy programme next year.
