With only a matter of weeks to go until the F1 season kicks off in Melbourne, this week has seen teams back at Catalunya for the final pre-season test before the Australian Grand Prix.
After poor weather conditions affected the opening two days on track, things improved over the course of the weekend where some seriously quick lap times were posted by the leading drivers.
The final test of the winter also saw Adrian Sutil on track for the first time since being confirmed as a Force India race driver for 2013, a debut in Marussia colours for Jules Bianchi and an unexpected opportunity to test for GP2 title winner Davide Valsecchi.
