Kevin Magnussen and McLaren were fastest on the second day in Bahrain today as the teams gradually began to pick up the pace.
However, they are still far from the sort of lap times they are likely to achieve in full qualifying form come April.
Kevin Magnussen made a great start to his official F1 career by topping the times for McLaren in Jerez
Once again it was a day of mixed fortunes for the teams, with Red Bull enduring another disaster while others successfully logged a lot of laps. Daniel Ricciardo completed only three laps in the RB10, without actually recording a time, before his team gave up for the day.
