The last race weekend of 2011 gets underway with three free practice sessions around the beautiful and brilliant Interlagos circuit. After a few less than stellar weekend, we've got our hopes pinned on Brazil to deliver something special. HRT have signed Pedro de la Rosa for next year, and on Friday, we're going to see another face in the car today as Jan Charouz takes Liuzzi's seat for 90 minutes.

Elsewhere, the watch is on for drivers who could potentially facing their last weekend. We know Rubens Barrichello does not have a confirmed seat yet, but he's adamant he's not approaching this race as though it is his last. There's also potentially going to be some awkwardness at Renault after Petrov's outburst, even though everyone says it's all fine.
