Soft tyres for top teamspublished at 16:14 British Summer Time 18 April 2015
Any talk of Mercedes and Ferrari going though this first part of qualifying without using the soft tyres can be forgotten.
They are all out there on the yellow-walled tyre now.
All eyes now on Alonsopublished at 16:12 British Summer Time 18 April 2015
So it's all down to Fernando Alonso now if McLaren are to make it into Q2 for the first time this season.
He's ninth at the moment but won't stay there.

Button out again!published at 16:07 British Summer Time 18 April 2015
Another miserable turn of events for McLaren's Jenson Button. He's crawled to a halt on his out lap. He also hit trouble early in FP1 and FP2.
McLaren boss Ron Dennis slaps his flanks in frustration in the garage. Goodness knows how Button is feeling.
"Dear oh dear. What a nightmare he is having this weekend," says BBC commentator Ben Edwards.
Rosberg leadspublished at 16:07 British Summer Time 18 April 2015
The early laps are being punched in now and it's Mercedes' Nico Rosberg out front.
He's done a 1:35.657, three tenths ahead of team-mat Lewis Hamilton.

Kimi Raikkonen: "OK, I have a lot of vibration, so I'll box this lap."
That vibration came from a big lock-up by the Ferrari driver as he went into turn one on his first hot lap. He's fifth of the five cars to have completed a lap so far.

Engineer to Lewis Hamilton: "It looks like it's calmed down but there are still some big gusts."
Gusting winds proved troublesome for the drivers in FP3.
Get involved - a lot of love for Arrivabene, #bbcf1published at 16:03 British Summer Time 18 April 2015
Eddie Jordan's chat with Ferrari boss Maurizio Arrivabene over on BBC TV has gone down very well with you guys.
Chris: Absolute legend, what a guy Maurizio Arrivabene... I'm watching far too much F1 lately just hoping for a Ferrari resurgence.
Callum Rowe: Yep. I'd call him a dude.
Elton Lam: Maurizio Arrivabene speaks sense. @ScuderiaFerrari's upturn in form is good for the sport and competition.

Arslan Malik: Ferrari can get the front row it's not out of the question but their long race pace look strong this good Ferrari have stepped up.
Neil Perry: Got a sneaky feeling Button will sneak into Quali 2 this time around.
Grant Bolters: Mercedes are not going to have it all their own way. Certainly Ferrari duo will fight them for that front row.

April 1942 - something in the water?published at 15:34 British Summer Time 18 April 2015
Just by way of a follow-up to the Jochen Rindt entry, it's interesting to note that three great names of F1 were all born within a few days of each other in the spring of 1942.
Team owner Sir Frank Williams was born on 16 April 1942 in South Shields, while Rindt was born in Mainz, Germany, just two days later on 18 April.
By that point, a six-day-old by the name of Carlos Reutemann was burbling away happily thousands of miles away in Sante Fe, Argentina...
