@Surendhar: As we don't know fuel loads its impossible to guess but I would say its safe to assume Ferrari isn't suddenly six seconds off the pace of Mercedes. They'll be testing various things.
@Leo: Headline times and tyres - Massa soft, Ericsson super soft, Hamilton medium, Kvyat medium, Grosjean medium, Raikkonen medium, Sainz medium, Button medium
@Phil,Maidenhead: They haven't been #blessed enough for him I don't think.
@J: Possibly, and you're right in saying reliability steeply increased over the winter last year.
STOP PRESS: Button sets a lap time. The McLaren driver moves to sixth with a 1:28.868.
@Vinay: The plan has always been to come out this afternoon.
Button's time was indeed a 1:28.868. Not a 1:26.
@IanAU: The teams are able to make changes based on a token system, which dictates which parts and how much upgrading they can do. The tokens available this year (32) are limited to 48% of the engine. Engines are homologated tomorrow but now in-season development has been allowed teams don't have to spend all the tokens before the deadline.
@formulax1: Mediums for Button.
@CrM: Indeed, everyone is saying the same. But that's the balance that must be made when the sport is struggling for money and refusing to address the cost crisis with the most basic of solutions.
Some of you mentioned Carmen Jorda earlier. Here's what her old GP3 team-mate had to say about her yesterday.
It should be noted Cregan's results were far from outstanding.
@Harish: That time was set on mediums.
@MrsHamilton: Not a stupid question at all. At this stage in the season, the team's are switching one car between drivers. They will all have another under build in the factory.
@J: I'll try and keep you informed later on when/if race simulations start.
Rosberg has lowered the benchmark further to a 1:25.365.
@VS: As the engines are homologated tomorrow, I imagine they will have to do so then.
@James: I have heard the rumours. All I can say to that is #godisthegreatest #blessedarethemeek
@rockedin123: For obvious reasons, Raikkonen didn't reveal that information to the media. He wasn't complaining at all, he was just stating the car was acting unpredictably during yesterday's session.
