Hello, after long break.
Well, I have watched video records from testing sessions, and it seems that BMW is as strong as Ferrari. I must point also that Brown GP is actually very close; it may turn to be black horse (sheep, duck, whatever =) ) of this season.
These team are now followed by Renault, Williams and McLaren. The last one has a lot of problems, namely with grip.
I don't know about red bull teams, they tend to hide current condition.
Force India is also mystery to me, but they omitted a lot of testing runs, so I would expect them to be at the end.
