Rio Haryanto emerges in the Manor. He'll be looking to get plenty of running in after a frustrating morning.
Romain Grosjean is also out as he gets in some valuable minutes before handing over to Esteban Gutierrez.
'The eighties were cooler'published at 13:15 Greenwich Mean Time 4 March 2016
Lewis Hamilton has been talking halos at lunch, and here is what he had to say:
“I love this sport and F1 cars are so unique in how they look. I feel they have lost the cool look they used to have in the 1980s and 1990s and this part is just too drastic. It is not F1 for me. If they do implement it, I hope we have a choice of whether we have to use it and are not forced to, because ultimately it is our safety.
“I understand safety is a huge issue and something we always have to work towards but this is not the one.”

Chief F1 writerFormula 1 bosses have decided to press ahead with the introduction of a new elimination-style qualifying system from the start of the season.
The idea was voted through unchanged on Friday by the world council of F1's governing body the FIA, sources say.
It means the system will be used for the first time at the season-opening Australian Grand Prix on 19 March.
The World Council has decided to ignore suggestions for tweaks to avoid an empty track at the end of qualifying.
The decision comes despite F1 commercial boss Bernie Ecclestone saying last week he had been told the timing software and on-screen television graphics could not be changed for the Melbourne race.

Manor did manage to sneak Rio Haryanto out for an installation lap before lunch. Hopefully that means they will be good to go in the afternoon.

Lewis Hamilton hands over to Nico Rosberg now.
I'd imagine the lunchtime conversation went something along the lines of: "Soz"
