Webber fastest in Barcelona

This first day of testing in Barcelona marked the start of the final session of pre-season testing. Thus, many teams are continuing their development work by adapting their latest developments or preparing their arrivals. Thus, the single-seaters that roam the Montmelo circuit will be subject to improvements during this week's tests, or even subsequently, before the Bahrain Grand Prix.

Therefore Mercedes revealed that its rear diffuser, one of the essential parts of the F1 2009-2010 (the multi-stage diffuser will be banned in 2011), will not appear on track before the Bahrain Grand Prix. It is therefore with great caution that we must analyze the Barcelona times, which are not very significant in order to develop a hierarchy.

Beyond the times, the problems keep coming for Virgin Racing. Last week, the Bicester-based team was unable to continue its development program normally, due to recurring hydraulic problems. This Thursday, while Nick Wirth's teams were hoping to improve the reliability of the VR-01, Lucas di Grassi made a mistake, damaging the car, which was unable to return to the track for the day.

Ferrari also had to deal with problems preventing the F10 from showing itself at length on the Montmelo circuit. The stop on the track Fernando Alonso even led to the appearance of the red flag at the start of the session. Plagued by electronic problems on his F10, the Spaniard had to wait a long time for the Team does not resolve the problem.

Before 12:30 p.m., Mark Webber set a convincing time, in 1:21:487, a time which would not be exceeded, despite the three hours of testing in the afternoon. With this time, the pilot Red Bull is still far from the Brawn GP cannon at the start of the 2009 season. Brackley's single-seaters surprised with astonishing times. Rubens Barrichello concluded the four-day session in Barcelona in 1. It remains for the teams to work, unless some prefer to advance hidden and only reveal their best assets in Bahrain.
