Barcelona F1 test times - day four: 21 February - 1pm

Full lap times, as of 1pm local time, on the fourth and final day of the F1 2013 group test at the Catalunya circuit near Barcelona.

After a cold and wet start, the track has dried out as the morning has progressed and the expected heavy rain appears unlikely to materialise. Lewis Hamilton continues to top the timesheets going into lunch, while Valtteri Bottas has been working on pit stop practice all morning and not set a fast lap. He is not expected to resume in the afternoon session.

There has been just one further red flag since 11am local time, with Giedo van der Garde's Caterham stopping near Campsa just 14 minutes before the hour-long lunch break.
