okay... BrawnGP has got to be running low fuel runs... 1 second clear of the field? I don't know if I should be
or 
and McLaren still at the bottom of the time sheets...
BrawnGP needs to secure sponsors if they wish to last more than 1 season. the best way for them to do so right now would be to go out and throw down the gauntlet at every test leading up to melbourne, hopefully sign a big name sponsor long term before some of the top teams stop sandbagging and show their real pace.
i'd expect teams like renault, ferrari, bmw, and in other years mclaren, to be sandbagging at these tests.
of course their pace could be genuine too... they did start the car a few months ahead of everyone else.
it should be an interesting start to the season with potential for 5 or more top teams in early races.
