F1

Because their areo is so good wouldn't be suprised if Red Bull took the lead again, they have never had the most powerful engine though.

Ferrari's most successful period was when they had a Frenchman and a Brit in charge of the team!  Read an article recently that essentially it won't be successful whilst its run like an Italian team.  Their management is pretty much a shambles,  Vettel could have won 2 maybe 3 races this year but for poor management decisions.  They need to get someone in of the calibre of Ross Brawn.  

Mercedes will just keep pumping money into F1 until they get fed up, or people stop buying their cars, then they will do a bunk
