Until tomorrow, cheerio!

"Oh good news for Ricciardo who finally manages to get out. 4th and final penalty free power unit in the car so let's hope it doesn't go boom!"
Lewis Hamilton complains of having no grip - a concern of many drivers during today's practice - on the hard tyres as Daniel Ricciardo finally re-emerges on the circuit.
How on earth did we forget this monster...

Meanwhile, Lewis Hamilton, Nico Rosberg, Sebastian Vettel and Kimi Raikkonen are all out on the hard tyre.
Kimi Raikkonen: "Do we want to keep just doing laps and laps? Because I'm getting nothing out of it. I'll do it if you want, but..."
Image source, LotusRomain Grosjean's return to the circuit in the Lotus sees him clock 1:29.086, the 12th fastest time, before he is told to box.
Meanwhile, Kimi Raikkonen is racking up the laps on his long run, much to his displeasure...
Force India on Twitter: A programme of long runs for us this afternoon, which means you won't see much in terms of eye-catching times. It's all about testing today!
Image source, LotusAfter his engine cover blew off earlier, Romain Grosjean has been waiting in the Lotus garage for the rear bodywork on his car to be repaired. Thankfully, that has now been done and out he goes for the closing stages.
One from the present day that almost made the cut...
Byron Afonso: The best livery this season is the Williams Martini livery. Simple, effective & good looking.

Red Bull are still hopeful of getting Daniel Ricciardo out for some time on the track as Lewis Hamilton heads in, having just complained about his seat over team radio.
He's complained about a warm seat in previous race weekends this season, while Kimi Raikkonen said his seat was hot in FP1.
Susie Wolff on Twitter: Loved every minute out there this morning.
