All times on medium tyres except for Vettel, Grosjean and Button

Pretty quiet on the circuit at the moment. There's just Sergio Perez testing away in the Force India and he's just improved with 1:25.315.

There are some things I'd forgotten related to F1. In instances like the above, I like to think I blanked it from my mind. Amazing.

Nico Rosberg clocked the fastest time on medium tyres in the first test with 1:24.867. Lewis Hamilton has just gone quicker, improving with 1:24.133.

He's no longer top, though, as Sebastian Vettel pops up with 1:23.595. That's on softs though.

This week started promisingly for McLaren-Honda, who are hoping to have made some progress up the grid this year after a dismal 2015; Fernando Alonso set the third fastest time on Tuesday. But as the week has gone by, sadly, that promise has ebbed away. The more you look at McLaren’s times, the more it looks as if they might not actually be that much better off than last year, at least at the start of the season. 

And Alonso himself came close to admitting it after finishing his running on Thursday. He described progress on reliability as "quite positive”. As for pace, the Spaniard said: “In terms of performance, I am a bit on a standby because it’s difficult to read the time during the winter. It’s always changing. Some days some of the top times they seem reachable, some other days they seem unreachable. A little bit confused with the performance of everybody else and ourselves as well.

"We wait for Australia, 5 o’clock. Everyone on track, same fuel load, same tyres for everybody and we get the answers. But I think there is still a lot of work to do. Hopefully we are much closer than last year also on the performance side.”

Daniel Ricciardo edges closer to Lewis Hamilton's pacesetting time, improving with 1:24.898. That's two tenths off Hamilton's effort with both times coming on the medium tyre.

Where do you see Red Bull in the pecking order this season?

F1 journalist Dan Knutson in Barcelona: "It’s another sunny day. Nobody can remember having eight straight days of testing at Barcelona without any rain. 

"There was a little bit of rain before the start of the session on the first day, but from then on the track has been dry every day. It rained quite a bit last Saturday, but there was no testing that day. 

"A couple of years ago it snowed here, but fortunately on the day after the test ended."

Alright Dan, rub it in why don't ya!

Jenson Button's moustache must be up there too?

After switching to softs, Romain Grosjean nudges Jenson Button out of P3 as he improves with 1:25.255.

Sebastian Vettel, as expected, ditched the halo after one lap and has been steadily improving with his timed laps, his latest effort a 1:25.648, set on medium tyres, knocks Button further down the order.

Here's some early times from testing. Nine of the drivers have completed timed laps. We are just waiting for Sergio Perez and Rio Haryanto, the latter not getting out until closer to lunch.
