New Mercedes completes private test at Barcelona

Mercedes' new F1 W03 will only be officially launched on Tuesday morning but that hasn't stopped the team from racking up kilometres in the car at a private test at Barcelona on Sunday. After carrying out a shakedown at Silverstone last week, Mercedes jetted out to Spain early, ahead of this week's second multi-team test at the Circuit de Catalunya. Earlier this month they had opted to test their 2011 car for three of the four-days of the opening pre-season Jerez test and so had a day in hand to use as they wished.
