Vettel leaps to P1 with his latest time, lowering the benchmark to a 1:44.547. Still no sign of the Mercedes drivers yet.
Other than their installation laps, that is
Ricciardo the only man yet to complete a lap.
@Me: I guess that just comes down to the way they are designed. There are no rules dictating which way tracks should run.
Button has jumped back to the top of the timing screens, 0.029s quicker than Vettel.
@ChrisinsunnyPerth: It was, the purpose was to get the first miles on the board for its power unit. As a filming day, the team was limited to 100 km.
Vettel not happy with the downshifts of his car.
@TheeUnderBrake: Alex Rossi is a good bet for that drive.
Alonso goes 1.6s clear of Vettel - but has the red-striped super soft tyre on, which would explain his sudden leap.
@Michael: Maybe not as dominant, but still the team to beat. Everyone can make changes to their engines this year to cut the gap but, crucially, Mercedes can as well.
Hamilton and Rosberg still in the garage.
Bottas slots into second on the soft tyre, before Massa jumps ahead of him by four tenths.
@ceedub: I think it will be interesting, as Ferrari has had a year to work out the areas it needs to change for Kimi. I'm really fascinated to see how Vettel does in his new surroundings. We won't really know until the summer.
@Michael: This is one of Hamilton's strongest tracks. I remember Button saying when they were at McLaren that Hamilton was on another level at Yas Marina.
Rosberg and Hamilton are now out on track.
TV replays show Kimi getting a little out of shape through the kerbs at Turn 12 as the back end steps out.
Both Mercs have started a flying lap on soft tyres.
Rosberg gets quite wide through the tight middle sector, he looks like he's lacking a bit of confidence in the rear of his car. Rosberg's first lap puts him P4.
Wroth remembering, as always, we don't know the fuel loads the drivers are running in this session.
Hamilton goes third fastest, ahead of Rosberg by seven tenths.
