It's another action-packed day in Barcelona, the seventh in the pre-season testing season to be accurate, with one more to go after today.
For several drivers, the next time they get behind the wheel of their car after today will be for official practice in Melbourne, two weeks from now.
This will be the case for Sebastian Vettel, Daniel Ricciardo, Esteban Ocon, Kevin Magnussen and Stoffel Vandoorne.
Mercedes, Renault, Williams and Sauber should once again rotate their drivers between the morning and afternoon sessions.
McLaren should be a big focus today after Fernando Alonso vented his frustrations yesterday Honda's inability to deliver a reliable and performing power unit.
It will also be interesting to see if Mercedes ups the ante once again against its rivals and clocks a lap below the 1:19 mark which many people are expecting.
As usual, join us at 9:00 CET for live timing and commentary.
