It’s the fifth and final day of testing at Barcelona today, the final chance for the teams to prepare for what will no doubt be a corker of an opening race in Melbourne at the end of March.  The last day of testing has been somewhat of a washout, but prior to the downpour, our photographers at the track snapped some comparison shots to show how cars have changed between the Barcelona test in February and this one in March.  You can call is a game of spot the difference if you like!
