Follow live coverage of the third day of the first pre-season test from Circuit de Barcelona-Catalunya with F1i.
The opening two days followed similar patterns as Sebastian Vettel set the pace for Ferrari and Mercedes racked up huge mileage. The latter has seen the W07 receiving innovative upgrades already, with more planned for Wednesday and Thursday.
Kimi Raikkonen will get his first chance to drive the new Ferrari during this test as he takes over from Vettel for the final two days, while there is a similar driver change at Red Bull as Daniil Kvyat replaces Daniel Ricciardo. With Felipe Massa in at Williams too it means Vettel, Ricciardo and Valtteri Bottas are already halfway through their testing schedules.
In a change of plans at Mercedes, Rosberg will again drive on Wednesday morning before handing over to Lewis Hamilton in the afternoon. McLaren is sticking to its plan of alternating its drivers so Jenson Button returns to the wheel of the MP4-31 which has already matched its lap total from the first two tests of 2015.
Former McLaren driver Kevin Magnussen also gets his first taste of his new Renault on the third day, with the team looking to recover from reliability issues on both days so far.
You can follow live coverage of both pre-season tests - including live timing - on F1i's live page here, while there are also galleries of all of the new cars.
Running will take place from 0900-1300 and 1400-1800 every day throughout the two tests, with the first taking place from February 22-25 and the second being held from March 1-4.
