Jenson Button, Fernando Alonso and Nico Rosberg will kick off the final Formula 1 preseason test at Barcelona this week as teams make their final preparations ahead of the Bahrain Grand Prix.
With just four days of testing remaining prior to the first race of the 2010 campaign, all nine current teams plus new outfits Virgin Racing and Lotus will attend the test that runs from Wednesday until Sunday at the Circuit de Catalunya. Although not all teams have finalized their driver plans for this week's test, most of them have now confirmed how they will split their test duties.
McLaren has decided to alternate its drivers over the course of the four days. Button will drive on the Wednesday and Friday of the test, while teammate Lewis Hamilton will test on the Thursday and Saturday.
Mercedes GP has opted for a similar tactic for its two drivers, with Rosberg driving on the first and third day, and Michael Schumacher taking the wheel on the other two days.
Ferrari is to run Alonso on the first two days of the test, while Felipe Massa will round off Ferrari's preparations by testing on Friday and Saturday.
The other teams that have so far confirmed their lineups are also giving both their drivers two successive days. Williams will run Nico Hulkenberg on the first two days before he hands over to Rubens Barrichello; Renault will run Vitaly Petrov on the first days before Robert Kubica takes over; while Vitantonio Liuzzi kicks off Force India's testing for the first two days before Adrian Sutil gets back in the car.
