The weirdest rumour is Grosjean to Haas. It doesn't make any sense on any front. It reminds me of how Glock/Kovalainen went to Virgin/Caterham or whatever they were called back in 2010.

The only "sense" this move has is if despite Renault take-over the team is in such a huge financial trouble they need another paydriver alongside Maldonado and Grosjean doesn't bring "enough" despite oil giant Total support I think.
