The start of the 2011 Formula 1 season in Bahrain is less than 40 days away, but today marks the beginning of the first official test session of the new championship year.
Taking place at the Valencia circuit in Spain, the three-day test will be the first time that many of the competing teams’ 2011 challengers will break cover, and will also be the first time that drivers get to sample Pirelli’s new racing tyres in anger – as the Italian firm becomes F1’s sole tyre supplier in place of Bridgestone.
As well as new tyres, 2011 sees the reintroduction of the KERS energy recovery system, which is used to boost power for short distances. And while the controversial F-duct and double diffusers have been ditched for this year, drivers will have to get used to movable rear wings.
The new wings can be altered by the driver at certain points on the track only, and for restricted times, in order to enhance overtaking. The wing should boost top speed by around 10mph by reducing drag.
