We've had a week for everyone to get to grips with their 2019 machines, now it's time for a second week of testing to turn things up! Teams have confirmed when their drivers will be in action, so you know when to tune in for your favourite.
The world champion will have this week's first use of Mercedes' W10 on Monday morning, before handing over to teammate Valtteri Bottas in the afternoon. The Silver Arrows drivers will split duties across the subsequent days – a familiar tactic for the constructors' champions, who rarely have to contend with reliability issues in these events.
Red Bull have effectively flipped their week-one schedule. Pierre Gasly starts in the car, meaning Verstappen will be at the wheel on the final day - typically when the 'hero' laps get put in, and when Red Bull will be as comfortable with their Honda power unit as they can be in pre-season - expect something eye-catching from the Dutchman.
Ferrari have changed tact for test two and will have both drivers in action each day, like Mercedes. Leclerc takes morning duties on Tuesday, with Vettel driving in the afternoon and the pattern alternating from there.
Renault's plan exactly matches that of last week. Both drivers will take the wheel each day, with Ricciardo following on from Nico Hulkenberg on the first day before the schedule alternates.
Raikkonen had the first drive of the C38, and he will also give it its final run of pre-season, with Antonio Giovinazzi taking duties on Tuesday and Thursday this week, while the Finn comes in on Wednesday and Friday.
When is Robert Kubica driving in preseason testing?
Kubica only drove on the final day of test one as Williams were beset by delays in getting the FW42 built. With a car now ready to test in earnest, George Russell kicks things off for Williams, meaning Kubica will get the final run on Friday, as well as a go on Wednesday.
Alonso has been long rumoured as a candidate to take part in McLaren's preseason testing, to provide detailed feedback on their new car. The Spaniard is not listed as taking part in the second test, although it has been strongly suggested that he will be present in Barcelona.
