Davide Rigon, Marc Gene and Pedro de la Rosa will stay on Ferrari's books for the 2014 season after they were retained as test and development drivers.
Former Williams and Minardi driver Gene joined Ferrari as a test driver back in 2004 and he will make it a decade at the Italian squad after extending his stay until at least the end of the year.
The 27-year-old Rigon, who has represented the Scuderia at two Young Driver Tests, has signed a new two-year contract that will see him stay on as test driver and compete in the World Endurance Championship in an AF Corse run Ferrari 458.
De La Rosa, a veteran F1 driver who claimed one podium during his spell at McLaren, joined Ferrari as a development driver following a long spell at Woking. The Spaniard also had stints with Arrows, Jaguar, Sauber and HRT.
