If conditions are changeable during the race then I expect Rosberg to win. Hamilton just seems to lose a tenth in changeable conditions; I think it's because his lap time comes from the brakes and you need to consistent conditions to maximise performance that way. The Mercedes will need to look over their shoulders at the start as the RBs have nothing to lose from taking a risk on the first lap.

Changeable conditions is all about strategy. See Silverstone.

Silverstone was decided by luck, not strategy. Ham had cold tires and had to pit, Vet had enough time due to his position on the track to call the stop when it started to rain. On the other hand Rai and Ros were just unlucky that it did not start to rain earlier or later.

One of the mercedes drivers should win barring an incident.. their closest competition is in 15th and 18th.....on second thought Hamilton will win after rosberg has some kind of mechanical issue as usual lol

Porsche's are out racing now. Stopped raining and brightening up.

They'll start F1 behind the SC for 7/8 laps and then jump in quickly for intermediates.

Whether he pitted for inters or not by luck, it still shows being on the right tyre at the right time is key. That's why many people take gambles in changeable conditions.

There maybe wasn't a genuine reason for him choosing to pit but it doesn't change the fact that being on Inters won him the race, hence strategy won.

Hopefully its completely dry by race time.....after a wet quali i think you can start the race on whatever tires you want based on the track conditions

Rosberg was miles away from each curb, lost his rear end and could not accelerate clean out of some corners...

Everybody made mistakes, Rosberg was among the few who did the least, and you´re giving him --- for it?
You wouldn´t even get out of the pitlane in these conditions.

Nope. The requirement to run both tyres is only lost if a driver uses intermediates or wets during a race.

You can START on whichever tyre you choose, though.

if its dry come race time, they can start on either of the slick compounds, but still have to use both compounds in the race
if the race starts behind the SC, i believe they have to run the full wets at the start
if its just a bit moist, they can do a normal start but on inters.
as soon as they run either wets or inters in the race, they no longer need to run both slick compounds

Rosberg was unlucky, Raikkonen was just stupid. He pitted because vettel overtook him and wanted to go to inters to gain back the position. As it turns out it wasn't nearly wet enough at that point for that.

[Konpattsh]

As sainz he is last he can take the upgrade engine from renault, the penalty for a new engine wont change something on his place on the grid

[Moose]

Do we already need to revisit what can happen in the rain with standing water all over the track?

Sure, you need to go slow.

If you go slow, you lose temperature in the tyres, and can't get any grip. There's a point with F1 cars where problems compound so much that they simply can't run any more.

Low grip leads to the driver slowing down, leads to the tyres cooling, leads to the driver slowing, leads to less downforce being generated, leads to the driver slowing, leads to the tyres cooling, leads to ... until suddenly you're doing 30mph to stay on the track, and you're not racing any more.

Correct, I was caught by a sneaky edited post

As for track conditions, having watched the Porsche race, they will be absolutely fine on wet tyres and quickly onto the intermediates.

Kimi made a gamble thinking the rain woulld come sooner and it didnt so he wore out his inters... what makes that stupid?...if the cars ahead of u are faster on track. Your best bet Is taking a gamble...... i see no stupidity in what Kimi and Ferrari decided to do ...

[QLDriver]

Looking at the weather radar, it appears that the rain should be more or less over now. So... an hour and 15 minutes for the track to dry... starting on inters?
