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.
There is also a first appearance for Adrian Sutil since being confirmed as the 22nd and final driver on the grid for the season ahead.
Barcelona test line-up – Friday 1 March:
Germany Red Bull-Renault
Germany Force India-Mercedes
Australia Toro Rosso-Ferrari
Giedo van der Garde
