19:40 Gutierrez brings the Haas back in. That's 77 laps in the books.

19:39 Wehrlein is back out in the Manor.

19:31 This is turning into a decent day for Haas, with Gutierrez now on his 72nd lap and showing respectable pace. Positive start for F1's new team.

19:30 Verstappen didn't improve last time round, despite that fast first sector.

19:29 Gutierrez improves to a 1m25.524s. He's on softs.

19:29 Ericsson has joined the 100 lap club. That's the seventh team to log that much distance today.

19:28 Both Gutierrez and Verstappen have just done personal bests in the first sector.

19:27 Verstappen improves to a 1m26.539s. Still slowest.

19:25 The most number of laps over the eight days of testing in Barcelona last year was 159 on the final day from Sauber's Felipe Nasr. Rosberg is now well beyond that mark.

19:22 Vettel, Rosberg, Verstappen and Ericsson are the only drivers on the track right now. Rosberg is in the high 1m27s. Only his 164th lap now.

19:20 An interesting nugget revealed by Gene Haas - the Ferrari engine spec being used in testing at present isn't the Melbourne one - an 'evolution' is planned before then:

19:16

19:15 Rosberg has indeed passed Vettel. Meanwhile, Perez is lapping consistently in the 1m32s on a set of softs. That's around three seconds off the pace of the Mercedes and Ferrari, suggesting the Mexican either has a lot of tyre degradation or is on a high-fuel run.

19:13 Earlier today news broke that Honda was replacing its F1 chief Yasuhisa Arai. The man himself has been talking about the decision and his role in a very tough 2015 season for the McLaren-Honda partnership:

19:13 Less than a tenth in it next time around, and Rosberg looked poised to overtake Vettel on the main straight.

19:11 Rosberg is currently chasing Vettel around with both the Mercedes and the Ferrari out on medium tyres. Rosberg was nearly seven tenths faster than Vettel last time through, so is catching quite rapidly.

19:10 That improvement from Bottas was on the soft tyre. His earlier best was set on mediums.

19:08 Bottas has just gone quicker in the Williams, improving to a 1m25.648s best. He's still sixth fastest overall though.

19:07 Sounds as though Vettel is practicing the start procedure. He's driven through the pits and revved the engine in a particular sequence before stopping at the other end to do a start and rejoin the action.

19:05 Vettel has just headed back out in the Ferrari. More than 100 laps already marks a substantial improvement over yesterday for the Scuderia.

19:01 And Gutierrez returns to the pits after his 68th lap.

18:59 Wehrlein is back out in the Manor. He's on mediums.

18:57 Verstappen improves to a 1m26.755s on mediums. He's still slowest.

18:54 Ricciardo is now out after half-an-hour in the pits. He's out on mediums. Gutierrez, on softs, is not far behind him.

18:50 Ericsson returns to the pits. He's up to 96 laps completed.

18:50 Ericsson, Bottas, Gutierrez and Alonso are currently on track. Bottas is on hards at the moment and lapping in the high 1m31s bracket.

18:47 Gutierrez is now up to seventh on a 1m25.873s - just a thousandth slower than Bottas's best time in the Williams. He's on soft rubber.

18:44 Gutierrez is on course to improve in the Haas. He's currently 10th and 3.875s off the pace.

18:43 Alonso just did his personal best in the final sector.

18:40 We've had only three red flags so far in pre-season testing. One for the Haas wing failure yesterday, and stoppages today caused by Toro Rosso and Renault.
