Giedo van der Garde claims that he'll be making a "big" announcement today. However, I can't imagine that he's landed a race seat. There are, offcially, six seats up for grade: two Force Indias, two Toro Rossos and two Hispanias, though I think we can rule the Toro Rossos out. And he was a part of the Spyker fiasco, which Colin Kolles apparently has bitter memories of. Force India, therefore, is the only real option (it's also the only one he's known to have been talking to). Van der Garde was concentrating on getting that second Marussia/Virgin drive before the team went with Jerome d'Ambrosio. It's know that he was talking with Force India for a race seat, but why would he concentrate on Marussia/Virgin if he could join Force India? I suppose you could make the case that he figured he had a better shot with Marussia/Virgin because he wasn't competing with Sutil, Liuzzi, di Resta and Hulkenberg. The problem is that Marussia/Virgin only signed Jerome d'Ambrosio a day or two ago, so there's very little chance that van der Garde has been able to negotiate a contract in just two days. Especially with four other drivers in contention for the two seats. The only way I could see it happening is if van der Garde was offered a contract, but elected to wait and see what Marussia/Virgin were doing. That, however, does not make sense, because who in their right mind would join Marussia/Virgin before Force India? Therefore, I suspect that Giedo van der Garde has signed a contract to be test and reserve driver for a team, probably Force India. The direct implication of this is that Paul di Resta is no longer Force India's test and reserve driver. Alternatively, Mercedes have a vacant test driver role since Nick Heidfeld left the team, first to test for Pirelli and then to race for Sauber. But I can't see Ross Brawn being too interested in him, and there has been nothing to connect van der Garde to Brackley. If Mercedes take anyone as test driver, it will probably be Paul di Resta or Nico Hulkenberg.
Unless van der Garde has somehow convinced Colin Kolles to take him on for 2011 with Hispania. I admit that my source on Kolles having bitter memories of his time with Spyker is something that I have only heard in passing, though given Kolles' behaviour - particularly his comments about Bruno Senna - it wouldn't surprise me if that were true. Giedo van der Garde was tied up in a contractual dispute between Spyker and Super Aguri, and ultimately went to Spyker, probably because of the Dutch connection. I don't think Kolles would have anything against him personally, but that might not stop him from discriminating against van der Garde.
So I suspect that van der Garde will be announced as a test driver tonight (assuming it happens), and he'll campaign in GP2 next season to try and win the title and improve his chances of getting a drive.
