Mercedes GP needs a second per lap to be above

This season he has no better looking for the German team. After the problems experienced during the past year, this year had not looks better and things seem to be confirmed with statements by the head of Mercedes GP, Ross Brawn. Apparently the car of Nico Rosberg and Michael Schumacher needed even a second per lap in order to be up.
The second is the time of advantage which brings him more or less the teams fighting, presumably for victory this year, Red Bull and Ferrari. The own Brawn expects the evolution release during the test of this week to improve the performance of the own. Especially in the area of the grip and stability, real Achilles heel of the silver cars during this offseason.
