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.
1) Felipe Nasr (Sauber) 1:21.545 108 laps
2) Kimi Raikkonen (Ferrari) 1:21.750 92 laps
3) Nico Rosberg (Mercedes) 1:21.982 151 laps
4) Felipe Massa (Williams) 1:22.276 71 laps
5) Pastor Maldonado (Lotus) 1:22.713 96 laps
6) Carlos Sainz Jr (Toro Rosso) 1:23.187 136 laps
7) Daniel Ricciardo (Red Bull) 1:23.901 48 laps
8) Fernando Alonso (McLaren) 1:35.553 32 laps
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."
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."
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.
Pastor Maldonado is still out there, along with Carlos Sainz Jr, Felipe Massa and Daniel Ricciardo.
F1 journalist Dan Knutson in Jerez: "Work has been going on behind the screens in the Red Bull garage for most of the day.
"With Daniil Kvyat doing 18 laps yesterday and Daniel Ricciardo doing just 12 so far today, it really has been a couple of wasted days for the team as far as getting mileage on the car is concerned."
Pastor Maldonado goes fourth quickest for Lotus with a 1:22.950, 1.4 seconds off the pace set by Felipe Nasr in the Sauber.
Here are the day's headlines:
- McLaren end day early because of power unit problems, but they managed 32 laps
- Felipe Nasr sets the pace for Sauber after track dries in Jerez
- Nico Rosberg clocks 120 laps, but loses time after stopping out on track
- Nasr spins, bringing out the first red flag of the day
- Lotus delayed because of telemetry issues
- Red Bull endure tough day with limited mileage after engine change
Hurrah, Ferrari fire up their car and send Kimi Raikkonen on his way, with Nico Rosberg and Felipe Massa following him down the pit lane.
The track falls silent.
Lotus are having an encouraging day with Pastor Maldonado passing his half century of laps before heading back to the pits for a few tweaks to the car.
With two hours to go, Felipe Nasr heads the timesheets with a 1:21.545, 0.8 seconds clear of Kimi Raikkonen's Ferrari. Mercedes' Nico Rosberg is third, four tenths adrift.
Felipe Massa is fourth, ahead of Daniel Ricciardo, Pastor Maldonado, Carlos Sainz Jr and Fernando Alonso.
F1 journalist Dan Knutson in Jerez: "Like the rest of the teams, Williams plan to put a number of upgrades on their car. Williams will run their Australian Grand Prix spec car, or something very close to that version, at the last pre-season test.
"'We are going to see changes between now and Melbourne,' chief technical officer Pat Symonds said. 'You will see them in the final days of the final Barcelona test.'"
But back comes Felipe Nasr, the Sauber driver clocking a 1:21.545 to bump Kimi Raikkonen down to second. We shouldn't read anything into this really, as we don't know what fuel loads they're running while different tyre compounds will also have an affect, too.
It's straight down to business for Ferrari's Kimi Raikkonen as the Finn pumps in a 1:22.351 which sends him flying to the top of the timesheets.
Break over at Ferrari as Kimi Raikkonen heads back out on track, with Williams' Felipe Massa and Sauber's Felipe Nasr for company.
Nico Rosberg's Mercedes spent some time on the back of a truck earlier today when the engine broke down during the German's run.
Sauber's Felipe Nasr lowers the benchmark to a 1:22.750 to knock Nico Rosberg down to second on the timesheets.
Looks like Red Bull have finished work on the car as Daniel Ricciardo is in the cockpit and raring to go. The Australian has only managed five laps today.
Nico Rosberg reaches his century of laps and he pumps in a 1:22.810, the first driver to get down into the 1m22s today, to go fastest. Sauber's Felipe Nasr drops to second, 0.944 seconds adrift.
