Follow live coverage and timing of the opening day of the Barcelona post-race test with F1i.
10 of the 11 teams will be running on Tuesday and Wednesday, the first of two occasions to test during the season. 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.
With four days of in-season testing in total - the second test takes place after the British Grand Prix - regulations dictate teams must run drivers who have started no more than two grands prix on two days.
A number of teams are running race drivers on at least one day this week, with Sebastian Vettel in the Ferrari on Tuesday while Nico Rosberg, Daniel Ricciardo, Jenson Button, Romain Grosjean and Pascal Wehrlein all also driving on the opening day.
F1i is present at the Circuit de Barcelona-Catalunya to bring you full live timing and coverage on our updated live page. Running takes place from 0900-1300 and 1400-1800 local time.
