The first time he has even been back on track was last week when he took the wheel of a kart. Because of testing bans in place this season in F1, Massa can't drive the current car he was running until Hungary. As he gets back up to speed, the FIA has granted him permission to drive a 2007-spec car fitted with GP2 tires.
Massa has also spent time on Ferrari's racing simulator. Word has it he's already mastered Barcelona and is working hard at beating the Interlagos circuit now. Before taking the wheel of the 2007 car, he still needs to pass an examination, but once he's cleared, he could be on track in Italy by Monday. This will be testing only as the driver isn't expected to compete for Ferrari any more this season.
