Leonardo: Can we have an anniversary reprise of the #thingskimifindsok, external challenge from last year?

Max Verstappen has just completed a number of quick laps, the fastest of which was a 1:22.172.

A slow and steady start for Fernando Alonso as he tiptoes round the track in 1:35.717.

That's all we've got for timed laps so far. Still waiting for the first appearance of the morning by Carlos Sainz's Toro Rosso.

Aero work for Kimi Raikkonen this morning. He's got those bid old cattle grid-style sensors attached to the back of his Ferrari.

Felipe Massa - he who announced his retirement only seven months ago - completed a mammoth 168 laps on Tuesday, and set fastest time into the bargain. He was under no illusions that Williams were in a position to challenge Mercedes, but he was optimistic enough to talk about possible podiums and said “maybe that is already a great job”. 

The veteran’s strongest message, however, was for team-mate Lance Stroll, whose three crashes in two days last week left the team in all sorts of trouble with spare parts, not to mention a damaged chassis. Massa effectively publicly pleaded with the 18-year-old to keep it on the straight and narrow once he takes over after lunch on Wednesday.

“Always when you lose a day it is not great,” Massa said. “Maybe something we did today we could have done last week, but it was not possible. But we managed to do a lot more today. We managed to get some good feelings from the car, we managed to see the car is reliable, which is important. We still have three days in front of us. We haven't got many parts, so we need to try to keep everything we can. It is so easy to go off.”

If I were Felipe Massa I'd be wanting to spend this morning in a hot bath after pounding the circuit for 168 laps yesterday but no, the veteran is back in the Williams today, sharing duties with Lance Stroll. It's a big week for Stroll after a couple of crashes last week.

Looks like everyone has been out. No, wait. Carlos Sainz is yet to emerge in the Toro Rosso. 

Nico Hulkenberg takes the Renault out for a spin - not literally - with the German once again sharing driving duties with Jolyon Palmer today.

Like McLaren, Renault had to change their engine in the morning, a move that was described as "precautionary" by Palmer, who managed just 15 laps yesterday.

A few of your fastest and slowest car predictions for 2017 are coming in now. Here,  Ian Jones has gone for Ferrari to be top dog this season.

Agree? Let's not forget that they were fastest on five of the eight days of testing last year. Very, very early days.

We've got a couple of times on the board, with Valtteri Bottas setting the early pace. The Finn does a 1:22.474 on the ultrasoft tyre, before shaving off 1.3 seconds on his next lap.

Max Verstappen, meanwhile, has done a 1:26.024 on the soft compound of tyre.

Testing... It's always hard to call who has made the best car after a few days of going round and round the Circuit de Barcelona-Catalunya, but that's exactly what we all find ourselves wanting to do.

Sure, Mercedes will be up there, but who do you think have also produced a fast motor ahead of the season-opener in Australia?

With 'first' being the fastest, who do you think will be the top three performers for the Australian Grand Prix? And who do you think will be the slowest?

Back to Ferrari and their pace. Lewis Hamilton believes they may have the quickest car this season after watching Mercedes' rivals produce consistently quick laps so far in testing.

On Tuesday, Sebastian Vettel was just 0.2 seconds slower than pacesetter Felipe Massa on a slower tyre and they are yet to reach for the two softest types of tyre. 

"Ferrari are possibly the favourites," Hamilton said. "We can't take our eyes off them they are doing such a great job. It is going to be close at the first race for sure."

Straightforward installation lap for Fernando Alonso. Meanwhile, a few other drivers are up and at it early doors with Valtteri Bottas out in the Mercedes this morning. Lewis Hamilton is in the car this afternoon.

No messing about from Fernando Alonso as he heads straight out on to the track in the McLaren.

He's the only driver out there so, by default, the below statement is correct. He is indeed fastest one.

At the start of test two, it was Williams’ turn to grab the headlines with a fastest time by Felipe Massa. And a Ferrari was again quicker than a Mercedes on headline times - by more than 0.5secs. Ferrari have impressed in pre-season testing far, to the extent that Lewis Hamilton said they were “possibly the favourites”. But was that a bit of kidology? We all know that headline testing times are meaningless, right?

There is only so much you can do to eliminate the variables, but one thing you can do is look at the length of the run and correct for the minimum amount of fuel that must have been in the car. Do that in the case of Tuesday, and guess who was quickest? Yep, Hamilton. But it was by only 0.01secs - and a Red Bull was only 0.1secs further back. So, judging by that, it could be close - really close - at the top. Fingers crossed. 

Hello! Welcome along to our coverage of day two of the second and final F1 test in Spain.

Felipe Massa topped the timesheet on Tuesday, with the Williams driver producing a marathon effort to finish on 168 laps for the day.

But there was more trouble for McLaren. An engine change in the morning - at least their fifth engine change in the two sessions of testing so far - curtailed their running, although Stoffel Vandoorne managed to make up for lost time in the afternoon.

Once again Ferrari impressed, and Lewis Hamilton appears to be getting a tad worried about their potential. Or is it all just mind games? We shall see.

Anyway, the track is open and testing is under way!

This is Kimi Raikkonen smiling. Well, as smiling as much as Kimi Raikkonen can smile. Tis a rare sight I am sure you will agree.

However, we might have to get used to it if Ferrari can deliver on their promising form so far in testing...
