Vettel fastest on day two for Ferrari, Ricciardo 2nd for Red Bull
Rosberg completes 172 laps, Alonso 119
That'll do from me for today then.
You've made it an enjoyable nine and a half hours and I sincerely hope you will help me do it all over again tomorrow.
Speaking of which, this man will be on the track for the first time.
Remember: No Kimi, no party.

Here's your times and laps from the second day of testing:
Vettel 1:22.810 (126 laps)
Ricciardo 1:23.525 (112)
Perez 1:23.650 (101)
Rosberg 1:24.867 (172)
Ericsson 1:25.237 (108)
Gutierrez 1:25.534 (79)
Bottas 1:25.648 (134)
Wehrlein 1:25.925 (71)
Alonso 1:26.082 (119)
Palmer 1:26.189 (42)
Verstappen 1:26.539 (121)
Actually, it will end on a red flag. Sebastian Vettel making certain that nobody knocks him off the top spot with a late run.
That'll do for now everyone, keep your powder dry.
I'd say that's a happy Fernando, which we like to see.
Nico Rosberg is in the paddock after a doozy of a shift.
172 laps, plus the 156 by Lewis Hamilton yesterday means Mercedes have totted up (gets out calculator) 328 laps over two days.
That's pretty much five full races around Circuit de Barcelona-Catalunya.
F1 journalist Dan Knutson in Barcelona: "Jolyon Palmer did only 37 laps on Monday because of software problems on the Renault.
“Disappointing first day I would say,” he said yesterday. “It’s been challenging. Usual first day issues. We would definitely have liked to get some more laps under our belt but we understood some issues, got some laps in at the end. We just need to work hard tonight and get a lot more in tomorrow.”
"Unfortunately he only completed 42 laps today before a power unit problem brought things to a halt.
"Meanwhile, Sebastian Vettel, Daniel Ricciardo, Nico Rosberg, Marcus Ericsson, Valtteri Bottas, Fernando Alonso and Max Verstappen have all done more than 100 laps today."
Can he? I'll run out of cakes at this rate...
We're nearly there folks, 20 more minutes...
There's an almighty Twitter spat going on between Mercedes and Red Bull right now.
They're sending each other crashes on YouTube clips and everything.
We've all had a couple.
It's all in good humour... I think.

I'm glad you asked Stephen Kiely.
Lewis Hamilton's best lap yesterday was a 1:25.409
Nico Rosberg's best today was a 1:24.867.
But there's barely anything to read into it, of course. Mercedes know they're quick and they've not been looking to top the time boards over the last two days.
One down, 10 remain.
If we've learned anything over the past two days, it's that the W07 is a workhorse.
Also, Nico Rosberg has been driving for getting on for nine hours now.
I've been typing for the same amount of time, but the purists might argue that Nico's job is a tad more exerting.

Crack out that champers Nico Rosberg, you have crushed your frenemy Lewis Hamilton into the dirt.
Hamilton's 156 laps yesterday have been swatted into the distance, as the German clocks up his 157th of the day.
Global domination awaits...
Quick! Give me my cake back.
Hold on! Nico Rosberg is back out!
155 laps, Hamilton had 156...
There's a sting in the tail yet...
Events are slowing down now as we wind towards 17:00 GMT (18:00 in Spain).
This could be a slow hour...
In the mean time, here's a really cool picture of the Mercedes.

I am officially reining in the Lola Lols now.
It's become such an unwieldy beast that people are critiquing it on the internet.
We never created it to be judged, we created it simply for the joy of humanity.
But, as we know, even the most innocent of creations are not invulnerable to the touch of human nature.
Therefore, like a beautiful butterfly, I shall release it into the yonder.
Be free my friend. You shall forever remain in our hearts.
(For those confused by what we're on about, scroll yourselves all the way down to 09:41 GMT this morning. Yes, this has been going on for six hours).
