And that's a wrap. Thanks for your company and hope to see you tomorrow when we can do it all over again before waving goodbye to Jerez for another year. Until then, it's good afternoon from me. Adios!

Lewis Hamilton will swap his bike for the Mercedes W06 tomorrow for the final day of this first test in Jerez. Jenson Button will be in action, too, as will Romain Grosjean, who will get his first go behind the wheel of the new Lotus.

So an encouraging day for McLaren, albeit it one which was curtailed because of an engine issue. Mercedes will be pleased with another 150 laps in the bag, which brings Nico Rosberg's lap total this week to an staggering 308.

Sauber and Toro Rosso managed more than 100 laps, too, while Ferrari and Lotus almost made the century. It was less successful for Red Bull who missed much of the day before a late flurry of laps from Daniel Ricciardo.

Felipe Nasr finishes fastest on day three of pre-season testing in Jerez.

Can you guess who is responsible? Yep, it's Pastor Maldonado, whose Lotus has rolled to a halt.

With one minute to go, we have a red flag!

Still no signs of any improvements at this stage, with Pastor Maldonado completing his final run before handing the car over to Romain Grosjean, who has yet to drive the car, for the last day of the test.

It's busy out on track with seven drivers circulating - Nico Rosberg, Daniel Ricciardo, Kimi Raikkonen, Felipe Massa, Felipe Nasr, Pastro Maldonado and Carlos Sainz Jr. Ten minutes to go.

Fernando Alonso and McLaren have completed the fewest laps of anybody today with 32, with Red Bull's Daniel Ricciardo only having achieved fractionally more at 35 so far. At the other end of the spectrum, Nico Rosberg is up to 145 laps, with Carlos Sainz Jr next up on 124.

F1 journalist Dan Knutson in Jerez: "Pit stop practice during a long run of laps by Nico Rosberg. The Mercedes W06 is covered in green flow-vis paint, so the mechanics will have lots of cleanup to do tonight."

Sauber:, external Felipe Nasr is still on top of the time sheet, now on a longer run.

Kimi Raikkonen has been joined by Felipe Nasr, Nico Rosberg and Pastor Maldonado as we approach the end of the session. No one coming close to beating the benchmark time set by Nasr.

F1 journalist Dan Knutson in Jerez: "Kimi Raikkonen is doing a long run. A Ferrari crew member showed him a pit board indicating 15 laps to go."

Kimi Raikkonen has the track to himself with 40 minutes remaining. The Finn has managed over 70 laps, today. Only Nico Rosberg and Carlos Sainz Jr have crossed the century mark.

F1 journalist Dan Knutson in Jerez: "The Sauber crew didn't bother putting the usual screens, so here's a shot of the fastest driver and car at the moment - Felipe Nasr and the Sauber - in the garage."

Mercedes:, external @nico_rosberg departs the garage with an almighty sneeze for another run...

Just 60 minutes remaining of today's session, with Felipe Nasr heading the timesheets, two tenths clear of Kimi Raikkonen's Ferrari.

Daniel Ricciardo pops into the pits and then heads straight back out. It looks like the Red Bull might finally get a decent run of laps under its belt before the day is out.
