Image source, Rex FeaturesIt's a bit like a dance off on the track at the moment. Mercedes have just done their little jig and said to Ferrari 'go on then, beat that'.
And beat that they do.
Kimi Raikkonen does the on-track equivalent of the snake across the dance floor with a mighty fine 1:34.338 to go three tenths clear of Mercedes, before Sebastian Vettel finishes things off with a breakdancing 1:34.001, sixth tenths faster than Mercedes.
It's like Run DMC versus Jason Nevins out there.
Another person who has registered a pretty good lap is Valtteri Bottas. He's just gone quickest of all with 1:34.681, a tenth quicker than Lewis Hamilton, who slides through Turn 17 and has to abandon his lap.

One person who has banged in a pretty good lap is Lance Stroll. He is seventh quickest, ahead of his team-mate Felipe Massa, on his first run on the ultrasofts. He didn't use them at all yesterday.
There looks to be a problem for Jolyon Palmer. He's the only driver yet to set a time and is circulating very slowly in the Renault.
Get to the choppa!

Red Bull have raft of updates coming. That is the good thing about them, when they see a problem they react and react very quickly.
Do Red Bull look like they have closed the gap?
Max Verstappen has just nipped ahead of Kimi Raikkonen into fourth, clocking 1:35.452.
Verstappen is still some way off the pace of the Mercedes, with the teenager 0.6s off Lewis Hamilton.

Stoffel Vandoorne's first timed lap sees him slot in P15 with 1:38.514.
Jolyon Palmer is in the pits. He is one of two drivers - the other being Kevin Magnussen - yet to set a time with half an hour gone.
Will the real Mercedes please stand up. Oh, there you are.
Lewis Hamilton goes top of the pile with 1:34.828, a tenth quicker than Sebastian Vettel.
Once again, it is looking like qualifying will be verrrrry close this afternoon.
Image source, Getty ImagesValtteri Bottas improves by three tenths of a second and is up to second, four tenths off Sebastian Vettel's benchmark time.
So it is Ferrari-Mercedes-Ferrari-Mercedes at the top of the order at the moment.
Adam Applebaum: If #Mclarenf1, external are any animal it's the duck-billed platypus. Sure it's technically all there but the pieces just look so wrong.
Image source, Getty ImagesSebastian Vettel moves ahead of Kimi Raikkonen with a 1:34.933 but here comes the Mercedes pair.
First, Valtterri Bottas cuts the timing beam in 1:35.623 to go P3 before Lewis Hamilton does a 1:35.700 to go P4. They are 0.69 and 0.76 off Vettel respectively, so the gap between Mercedes and Ferrari is much like it was yesterday.
