The final F1 test of the winter continues with a second day of running at Catalunya, although poor weather again seems to set to hamper teams in their programmes on track.
Most teams have elected to make a change to the driver line-ups, with Sebastian Vettel,
Fernando Alonso and
Jenson Button amongst those appearing on track for the first time this week.
