Formula One fever is definitely heating up as most of the teams are already in full swing with testing leading up to the season-opening race in Bahrain later this month.

While there’s no shortage in storylines for the 2010 season – Michael Schumacher’s return, Jenson Button’s title defense, and the new teams making their F1 debuts, to name a few – one intriguing subplot that hasn’t been mentioned a great deal is the return to racing for one Felipe Massa.

If you recall, Massa sustained a pretty serious head injury at last year’s Hungarian Grand Prix, forcing him to be shelved for the remainder of the season. Now that Massa is back – he’s got a new teammate too in two-time World Champ Fernando Alonso – in Ferrari->ke252, everybody’s going to be keeping a close eye on him to see how he shakes off those psychological cobwebs in his first few races.

That being said, we have two videos of the aforementioned Brazilian doing some test runs in Jerez last month, as well as a more recent dry test run in Bahrain. From the looks of things, Massa seems to be comfortable sitting behind the F10 during testing and except for a few oversteering here and there, the Brazilian looks to be back to his old self.

Whether or not that’s bad news for the rest of the grid is another question altogether. But as far as we’re concerned, we’re just happy to see him back on track after that life-threatening accident last year.
