Paul Hembery (Pirelli Motorsport Director) said, "All the teams will have their new cars in Barcelona and the entire range of 2013 P Zero tyres will be at their disposal. Barcelona is a circuit that the teams have plenty of data on already, which is useful for comparison purposes. So it should be possible for them to carry out plenty of production work to help understand how their new cars interact with our latest generation of tyres, which are generally softer and faster than last year with deliberately increased degradation. The limiting factor at the opening test in Jerez earlier this month was the abrasiveness of the track, so hopefully conditions will be more representative this time. There is always the potential for low ambient temperatures though last year we actually saw some ice on the track in the morning."
Barcelona is well known as an extremely challenging circuit for tyres, with the front left tyre in particular subjected to a lot of work. This is because of the high number of high speed right hand corners on this 4.655 km track. The long right hander at turn three puts the most energy through the front left tyre equating to a load of 3.9g. The rear tyres also have to withstand plenty of stress in order to provide the combined traction needed coming out of the slower corners.
There are a wide variety of corners in the third and final sector of the circuit and it is the most demanding part of the track on the driver. A compromise in setup is needed on this track to deal with the many different speeds and corners. But the teams will be altering many more parameters than they would during a race weekend in order to see the effects of setup changes on the cars and tyres.
