Wait until we see how they perform with the australia package tomorow and on Sundaymclaren_mircea wrote:Jenson's impressions about mp4-29 behaviour after Day 2.
"We were still able to do a long-run on high-fuel this afternoon. The basic car is good, and there’s a great deal of potential there, but there’s still a lot of work to do. We have a good understanding of the power-unit, and we know how to race it, but, in terms of balance and grip, the car isn’t quite there yet.
"But I know we’ve got some good improvements in the pipeline – and they should help us close the gap to the front of the grid.
Because of the fact about the balance and grip I'm starting to be worried![]()
But if Mclaren hasn't run any updates it's not such a dangerour situation, because Ferrari and Mercedes already started to put new parts on the car. What do you think about this situation @Pup?

EDIT: @Pup Indeed, Jenson said it was a problem with the gearbox.
