Image source, @Circuitcat_engA strong day for Ferrari, but plenty to mull over at McLaren.
Will it come together for them tomorrow? It's their last chance before the season gets under way.
I'll be back bright and early tomorrow morning for the final day of testing. Join me then!
Mr Thomas: Surely all teams are sandbagging. Drivers saying cars are demanding to drive yet doing 150 laps in a day?!

That's it for the penultimate day of testing.
Sebastian Vettel tops the timesheets with that fast lap he got in the morning.
Sebastian Vettel is also taking the chance to squeeze a couple more laps in. He's already passed 150 for the day - more than two Spanish GPs worth of laps.
We've got Daniel Ricciardo and Pascal Wehrlein on the circuit as we enter the final 10 minutes of the penultimate test.
Question is, will McLaren get back out? No sign of them yet and the clock is against then...
Daniel Jones: Congrats to Lance Stroll for keeping it on the track for 85 laps. Maybe an update for @WilliamsRacing, external with the money saved.
Ziaulhaq Daulazai: Always the same with Ferrari, impressive testing but come AUS Q3 Mercedes run away with an easy 1,2.
Chris Marsh: Re: 16.41 If he starts running now he might.
Stoffel Vandoorne is still on 48 laps for the day. Will he reach the half century for McLaren? He's in the garage at the moment with 20 minutes remaining...
We're heading towards a fairly undramatic end to the day with just four cars out on the track at the moment, although three of those are the expected front runners - Mercedes, Ferrari and Red Bull. Toro Rosso have managed to get Daniil Kvyat back on the track.
Graham Martin:@LewisHamilton, external has only done 4 more laps than Vandoorne who's basically running around without an engine ;- )
Image source, .F1 journalist Dan Knutson in Barcelona: More trouble at McLaren?
Stoffel Vandoorne lifted off the throttle as he got towards the end of the main straight. He pulled to the inside of the track, almost stopped, then drove slowly back to the pits and got out the car.
There is a small but very vocal Vandoorne fan club in the grandstands opposite the McLaren pit. They cheer loudly, clap and blow air horns each time he comes in to the pits or leaves them.
1) Sebastian Vettel - 134 laps
2) Esteban Ocon - 126 laps
3) Daniel Ricciardo - 109 laps
4) Kevin Magnussen - 91 laps
5) Marcus Ericsson - 88 laps
6) Daniil Kvyat - 86 laps
7) Lance Stroll - 85 laps
8) Valtteri Bottas - 73 laps
9) Felipe Massa - 61 laps
10) Jolyon Palmer - 53 laps
11) Lewis Hamilton - 52 laps
12) Stoffel Vandoorne - 48 laps
13) Pascal Wehrlein - 33 laps
Rachel T: Get out of town. No-one 'deserves' a fast car. Alonso has made one bad career move after another since 2006.
Michael Simmons: Alonso is one of the best out there but as for Honda Jury Still Out.
After completing his race simulation earlier this afternoon Sebastian Vettel is back out on the track for the final 45 minutes. He's got super-softs on his Ferrari.
