Follow live coverage of the penultimate day of pre-season testing from the Circuit de Catalunya with F1i.
We will bring you live timing and commentary throughout the day as the teams introduce upgrades ahead of the first race in Melbourne in two weeks. While Williams was fastest on the opening day, the grid was left under no illusions as to the Mercedes pace after Nico Rosberg went comfortably quickest on the soft tyre on day two.
Kevin Magnussen returns for McLaren for the first time since the end of last season as he fills in for Fernando Alonso, who is continuing to recover from his accident on the final day of the second test. Magnussen will drive the MP4-30, which enjoyed its most productive day by far on Friday as Jenson Button completed over 100 laps.
Daniel Ricciardo is the only driver who will be driving on both days of the weekend as he takes over the RB11 from Daniil Kvyat, while Lewis Hamilton, Kimi Raikkonen, Felipe Massa, Romain Grosjean, Carlos Sainz Jr and Marcus Ericsson will all complete their final day of testing before the first race.
