That concludes our testing live blog!
It's been a mega three days (very long as well). Red Bull look strong, while Aston Martin look like they could be the surprise of the season in Bahrain.
Join us on Thursday for when we launch our next live blog - for media day - in Bahrain.
See you then!
That's that. It's over.
Well that's the end of the proper running. Time for the usual VSC, red flag etc. tests.
Perez, Hamilton, Bottas, Leclerc, Sainz, Tsunoda, Magnussen, Russell, Alonso and Drugovich.
Top 10: Perez, Hamilton, Bottas, Leclerc, Sainz, Tsunoda, Magnussen, Russell, Alonso and Drugovich.
Running on the C5, Bottas moves into third for Alfa Romeo. 120 laps on the board for the Finn today.
Checo tops the charts

Perez finds 0.3s to extend his advantage at the top. Ominious.
Top 10: Perez, Hamilton, Leclerc, Sainz, Tsunoda, Magnussen, Russell, Alonso, Bottas and Drugovich.
Magnussen finds more time on his low fuel run - moving up to sixth ahead of Russell and Alonso.
More low fuel runs - Bottas goes eighth on the C4s, 0.8s off.
Magnussen goes sixth fastest on the C4s now, 1.2s off Perez's top time.
Hamilton improves but he can't topple Perez for top spot - just 0.048s between the pair.
Tsunoda moves up to fifth on the C4s, 0.7s off.
It's a 1m30.616s for the Red Bull driver, 0.165s ahead of Hamilton.
Pirelli believe next week's Bahrain GP will be a two-stop race.
Hamilton goes quickest with a 1m30.781s on the C5s, 0.243s ahead of Leclerc's benchmark from earlier.
A glory run for Hamilton. He's on the C5s now.
Top 10: Leclerc, Sainz, Hamilton, Russell, Alonso, Perez, Drugovich, Tsunoda, Norris and Gasly.
Perez's lap is ruined by Sainz in the final sector. A shame.
Perez is now circulating on the C4s.
Hamilton slots in ahead of his teammate on the C4s, 0.2s off Leclerc.
That means all of the top four - Leclerc, Sainz, Hamilton and Russell - have done their best lap on the C4.
Hamilton is now out on the C4s... one to watch!
