Follow live coverage and timing of the final day of the Barcelona post-race test with F1i.
There has been a late change to the driver line-up with Pascal Wehrlein promoted to the Mercedes in place of Esteban Ocon. The move means Mercedes will not be able to run Lewis Hamilton during the second test after Silverstone.
With four days of in-season testing in total, regulations dictate teams must run drivers who have started no more than two grands prix on two days. As Nico Rosberg drove on the opening day of this week's test and Wehrlein has started five races, Mercedes must run a young driver on both days of the second in-season test. The team has already confirmed Ocon will drive on at least one of the days.
Spanish Grand Prix winner Max Verstappen is back in the Red Bull on day two in Barcelona, with Daniil Kvyat also on track for Toro Rosso. The other race drivers appearing are Felipe Massa at Williams, Kevin Magnussen at Renault and Esteban Gutierrez at Haas.
Only Sauber is not present at the Circuit de Barcelona-Catalunya, with the team cancelling its running due to a lack of new parts and suitable driver to test.
