20:14 We'll have more from the paddock throughout the afternoon and evening, and the coming days, before the second test.

20:13 Here's our wrap of the final day of this first test:

F1 testing 2017: Ferrari's Raikkonen leads final day of first test

Ferrari topped the final day of the first Formula 1 pre-season test of 2017, with Kimi Raikkonen outpacing Max Verstappen's Red Bull

20:04

20:02 FINAL LAP COUNT:
Raikkonen 93
Verstappen 85
Palmer 39
Grosjean 118
Giovinazzi 84
Perez 82
Vandoorne 67
Bottas 68
Hulkenberg 51
Kvyat 1

20:02 Perez heads back into the pits, followed by Vandoorne and Raikkonen and that's it for the on-track action here in Spain.

20:01 Vandoorne completes his final lap of the day, posting a 1m23.593s. Just three cars left now.

20:00 And that's the final chequered flag of this first pre-season test. Raikkonen ends the day fastest on a 1m20.872s.

19:59 Verstappen is back in, and with just a minute to go it's not looking like anyone is going to do anything spectacular on pace.

19:58 And Vandoorne has now headed out.

19:57 Raikkonen, Verstappen, Grosjean and Perez are the only drivers on track with just over two minutes to go.

19:53 You've been great at getting in touch with us this week – so here's another opportunity to be heard!

The first test is drawing to a close and there is no shortage of talking points – think Mercedes flying, Ferrari starring, Stroll shunting, McLaren struggling...you get the picture.

So, who has a question for GARY ANDERSON? Get in touch on Twitter using #AskGaryF1 and we'll pick out the best for Gary's next feature on Autosport.

19:53 Bit of a wobble for Perez out of the final chicane, and he comes round to complete a 1m26.118s.

19:52 Perez is back out and starts his first flier of this run on medium-compound Pirellis.

19:51 And he improves to a 1m22.309s to take fourth place from Giovinazzi.

19:49 We've updated today's gallery, which includes several pics of the Sauber:

19:45 Great news for Sauber fans, as Giovinazzi improves to a 1m22.401s. He's on ultra-softs and up in fourth.

19:43 Quickest on track at the moment is Palmer, in the high 1m23s. Just 16 minutes of this first pre-season test remaining. Still time for some drama.

19:39 Raikkonen dives into the pits, leaving just three cars on track.

19:38 With just over 20 minutes to go, Raikkonen, Palmer, Perez and Grosjean are all on track.

19:38 Palmer goes third fastest with a 1m21.778s.

19:36 Raikkonen does push again, but despite a new best time through the final sector he is four tenths down on his fastest.

19:35 Another improvement for Giovinazzi on the ultra-softs, while Raikkonen has backed off for two laps in the row. Will he try again on this set of softs? We'd all love to see an ultra-soft run, if Ferrari is listening (we suspect it has better things to do).

19:31 It's a 1m20.8s for Raikkonen on the softs. Giovinazzi has also improved in the Sauber, on ultra-softs.

19:30 Raikkonen is improving again - how fast can the Ferrari go this time?

19:27

Renault has tried a new colour on its RS17's livery, kinda. Pic: LAT

19:25 Grosjean has passed the 100-lap mark for Haas, an impressive feat on a day where a lot of the running was compromised by the wet test conditions.

19:23 That is McLaren's fastest time of the week - a fraction faster than Alonso has managed at this test.
