Lee McKenzie has filed a report on the first appearance of Force India's new car for 2015.

Nico Hulkenberg will drive the VMJ08 until Sunday when he'll hand over to team-mate Sergio Perez for the last day of running - meaning the Mexican will have just one day to acclimatise himself with the car before the new season begins in Australia on 13-15 March.

So, good news for Manor Marussia this afternoon.

You can get in touch with your thoughts on that, or any F1 yarn, using #bbcf1

Jenson Button's McLaren has done 67 laps and has a best time of 1:28.052. However, the Briton has yet to put on anything quicker than the medium tyre and is also understood to still be on reduced power

The 2009 world champion is second-last, ahead only of the Force India of Nico Hulkenberg. The German is now on the medium compound tyre, though, and has moved to within eight-tenths of the MP4-30 after 25 laps.

There's been a flurry of activity and in it all I neglected to say that Valtteri Bottas now tops the timesheets.

The Williams driver has done a 1:23.995 on the soft tyre and has put up 74 laps so far.

The Sauber of Felipe Nasr drops to second, but as yesterday the C34 becomes the first car to bring up 100 laps. Almost simultaneously Sebastian Vettel and Max Verstappen do likewise for Ferrari and Toro Rosso.

Kvyat's car is cleared from harm's way and we're off again. Just under two and a half hours remain.

Manor Marussia have been named on a 10-team Formula 1 entry list on Friday, subject to conditions that included full compliance with the 2015 technical regulations.

The list, which does not include the failed Caterham team, said the revived Manor Marussia F1 team would compete with Ferrari engines.

Marussia, who have clawed their way back from the brink of oblivion, have named Britain's Will Stevens as one of their drivers. However, the governing FIA said that was subject to him holding a super licence.

F1 journalist Dan Knutson: "The Red Bull sounded a bit sick as it went by the media centre. Whether that was because Daniil Kyvat was backing out of the throttle or because the car had a problem is not known. But he stopped down at Turn 1 and that brought out the red flag."

"Felipe Nasr of Sauber and Pastor Maldonado of Lotus are in the middle of race simulations."

"Sebastian Vettel is focusing on long runs this afternoon, but Ferrari say that a specific race simulation - where teams run the full distance, do pit stops, pick a tyre strategy etc - is not planned. Which is a shame, as we have not yet seen a 'race sim' from Ferrari and it would be nice to look at their times and see how they compared with others who have - notably Mercedes, Williams and Red Bull."

It's been a bright start for Force India and the new VJM08, which only broke cover just before lunch but has already made it into double figures in terms of laps completed.

Nico Hulkenberg's best time of 1:29.866 on an unmarked Pirelli development hints at some good pace in the car. It will be interesting to see how it goes with the soft or super-soft tyre on.

"Kimi Raikkonen became a father in January. He's not the most talkative driver in the paddock anyway, but he refuses to talk about his son, saying that concerns his private life."

Berwyn Thomas: "Great to see your pic of Fernando back on his feet and looking good."

Pete Thorneycroft: "Lotus livery looking cool."

David Anderson: "Start my new job next month. Is it a good excuse to be in my underwear watching testing. Another 50 laps please McLaren."

Alex Withington: "Without doubt the best day of testing so far for McLaren. Phew! Maybe they will try some shorter/low fuel runs this afternoon."

Sean Barlow: "If McLaren keep putting in the laps, they might be somewhere other than tail enders for the opening sequence of flyaways."

We're 24 minutes into the afternoon session and it's largely as-you-were in terms of the standings.

Daniil Kvyat's Red Bull has improved to sixth place after a 1:27.257, while Sebastian Vettel's Ferrari is back on the hard tyres and doing a long run.

Jenson's Button's McLaren, meanwhile, is closing in on a half-century of laps today.

The case of Max Verstappen and his missing greens could be solved (see 12:53).

I don't want to leap to any wild assumptions, but it seems only too clear the caterers at Honda have swiped the paddock's entire supply of broccoli to make ornate table centres.

We're back under way in Barcelona.

Good grief you lot are good. Some of you even had the temerity to tell me this was even easier than the first one.

Apart from one or two wrong answers (I'm delighted I duped one of you into thinking it was Grosjean and Alonso at Spa a couple of years ago) pretty much 99% of you told me it was the inverted, roll-bar-less Sauber of Pedro Diniz being skirted by the Williams of the magnificent Alex Zanardi. Nurburgring 1999.

Well done to all those who got it right and thanks so much for playing.

I'm off to the archive to find something nice and obscure for tomorrow. I wonder if Toshio Suzuki ever binned an F1 car in an interesting way?

At 17, Toro Rosso rookie Max Vertsappen has maybe still got a bit of growing to do, but he won't get very far without any greens in his system.

I mean, just look at what his team has just tweeted, external him eating this luchtime. Spaghetti, grated carrot and, erm, Wotsits.

Tsk tsk.

McLaren's Fernando Alonso has posted a YouTube message, external giving an update on his condition after his crash in Barcelona last weekend:

In it, he says: "Hello everyone. as you can see I'm completely fine, I would like to be in the test this week but the doctors' recommendations are to wait a little bit, a couple of days.

"But I will rest this weekend and give you updates next week with progress and see you very soon on the track, and thanks for all the support."

"The Mercedes, with Nico Rosberg at wheel, looks in a different class. Jenson Button has had strong morning compared to previous days testing this season. And also looking committed out there was Max Verstappen who continues to impress his Toro Rosso team.

"Nico Hulkenberg is delighted to get out at last in his 2015 challenger. If all looks well with the car expect a busy afternoon from him."
