Felipe Massa has been tipped to give Ferrari's 2012 car its official debut next month.
The first official test of the winter, at Jerez, kicks off on February 7, and Spain's Marca newspaper said the likely pilot is Brazilian Massa.
On the same day, Mark Webber will reportedly give Red Bull's championship-defending challenger its debut, before his teammate Sebastian Vettel takes over on the following days.
Ferrari's plan appears similar, with Marca saying Fernando Alonso is next in line after Massa to drive Maranello's 2012 single seater at the southern Spanish venue.
The newspaper said Alonso and Vettel, likely championship challengers this year, will surely meet on the circuit on day three of the test, on February 9.
Ferrari's 2012 project is codenamed 663.
Marca said it is possible the car will make an unofficial debut on February 3 at Ferrari's Fiorano test track, when the single seater will be revealed to the media for the first time.
