Keep up to date with the final pre-season test from Barcelona with F1i's live timing and commentary.
We will bring you all the action from the second day of the final test at the Circuit de Catalunya, with live commentary running throughout the day. McLaren and Mercedes looking to bounce back from disappointing days on Thursday, while Williams will hope to build on the fastest time.
McLaren was hit by a hydraulic leak which ended its running after just seven laps on the opening day, leaving the team with a little over 200 laps under its belt after nine days of testing. Mercedes has enjoyed much better mileage so far this pre-season, but an MGU-K failure saw Lewis Hamilton limited to 48 laps.
Friday's running will see Jenson Button continue in the McLaren-Honda while Nico Rosberg takes over the Mercedes. Daniil Kvyat remains in the Red Bull, but Sebastian Vettel is back in the Ferrari SF15-T and Valtteri Bottas will jump in to the Williams after team-mate Felipe Massa set the pace on Thursday.
Each day of the final test runs as two sessions, with the morning running taking place from 09:00-13:00 and then the afternoon from 14:00 to 18:00 local time.
