With less than a month to go until the 2013 Formula 1 season kicks off in Australia, the teams have been putting their cars through their paces in testing.
Following the first pre-season test in Jerez earlier this month, Barcelona has played host to the second cluster of warm-up sessions.
Here are some of the best photos from the first three days at the Circuit de Catalunya, with the final pre-season test set to get under way at the same location on 28 February.
