F2 champion Oscar Piastri began reserve duties at Alpine whilst rivals from the support series joined the Australian as teams logged laps in both standard 2021 machinery and 'mule cars' aimed at gathering data on Pirelli's new tyres for 2022.
Robert Shwartzman drove for Ferrari on day one but swapped to Haas for the second day, finishing top of the timesheets.
GPFans has compiled a photo gallery from post-season testing at the Yas Marina Circuit.
