Jerez (Spain), February 13th, 2011 – The second Formula One group test in Jerez has drawn to a close, with Pirelli PZero tyres enjoying another faultless run over the four days of testing in the south of Spain.

Following on from the first official test of the year in Valencia, the Formula One teams again had the chance to sample the full range of Pirelli tyres on a circuit with quite different characteristics, which last hosted a Grand Prix in 1997. There was a wide range of temperatures experienced and a sudden burst of rain only during the last 10 minutes of the final day, meaning that the teams focussed on the dry compounds that they had previously selected to test.

With some teams only running their 2011 cars and drivers for the first time, and others concentrating on understanding the new technical regulations, a number of different programmes were being carried out by all the squads. Most of the principal tyre work was carried out by the teams over the last two days of the four-day session, providing a wide range of results as the teams got to know their new cars better.

The characteristics of the Jerez circuit, which contains a wide variety of medium to highspeed corners, meant that the supersoft tyres saw very little action with the teams instead mostly looking at the soft, medium and hard compounds. Many of them were trying longer runs and race simulations for the first time as they expanded their development programmes.

Over the four days, four different driver and car combinations set the fastest time, underlining the adaptability of Pirelli’s PZero covers to a wide variety of different machinery. Such is the pace of development in Formula One, that on average the top times were more than three seconds faster than the times set by Pirelli during initial private tests at Jerez with the Toyota TF109 last September.

Pirelli’s motorsport director Paul Hembery said: “We’ve accumulated a huge amount of data, which we will now be analysing closely before the next test in just a few day’s time in Barcelona. Unfortunately there were several red flags over the four days here due to cars going off and other non-tyre related incidents, which meant that there were quite a few teams that did not manage to complete the full programmes that they anticipated. That affected us to some extent too but from our general point of view, we enjoyed perfect reliability once more and saw some longer runs than we had seen previously at Valencia. From what we learned from those so far, we believe that we’re still on course to see two pit stops per race, which obviously might be one stop on some circuits and three stops on others, depending on the individual cars and track characteristics. A number of drivers have mentioned to me that our tyres are going to be great fun to race with, which is exactly what we are aiming for.”

All 12 Formula One teams will now head to Barcelona for the final European group test of the season, which will take place on the Circuit de Catalunya. Unlike Jerez, it is a venue that all the teams are extremely familiar with, being a favoured venue for testing and also the home of the Spanish Grand Prix. Pirelli will bring a modified version of the supersoft and soft tyres, in response to feedback from the teams following the first official tests, featuring the latest evolutions of the PZero rubber.

Milan, February 9th 2011 – Just one week after the opening official test session of the year
in Valencia, Pirelli is back on track once more for the second group test, which covers
four days on the Spanish circuit of Jerez from February 10-13.
The Jerez circuit, which last hosted a Formula One Grand Prix in 1997, presents quite a
contrast to Valencia, enabling the teams to explore different characteristics of the new
PZero rubber, which will be exclusively supplied to the Formula One World Championship
in a three-year agreement lasting to 2013.
Pirelli will bring all four compounds of slick tyre – supersoft, soft, medium and hard – to
the Spanish circuit, as well as the intermediate and wet tyre. Dry conditions in Valencia
last week meant that the rain tyres were hardly used, but Pirelli is well-prepared if the
weather in Jerez turns wet.
The supersoft compound slick tyre offers optimum performance but over a limited period
of time. The soft version provides similar performance but is slighter longer lasting. The
medium compound provides a balance between endurance and performance, while the
hard version is for longer distance running.
For the Jerez tests this week, the medium compound has been further developed, in
response to data acquired during testing and comments from the teams and drivers.
Every car will receive a maximum allocation of 30 sets of tyres in Jerez, part of the overall
allocation of 100 sets of tyres for the four pre-season tests.
Pirelli’s motorsport director Paul Hembery commented: “The feedback from all the drivers
and teams after Valencia was very positive, but it is still early days and there’s a lot of
work to go through; particularly with all the new cars. The four days at Jerez will allow the
teams to get used to our tyres on a circuit with different characteristics, in order to
explore other aspects of their performance. The changes we have made to the medium
compounds are not big, but they constitute another small step in the evolution of our
PZero rubber, which as we have already seen, should help improve the spectacle during
the coming season. Obviously the Formula One news this week has been dominated by
Robert Kubica’s accident in Italy, and I know that I speak for everyone at Pirelli in wishing
him an extremely speedy recovery.”
Pirelli was previously at Jerez last September, part of the 18,000-kilometre private testing
campaign with Pedro de la Rosa and the Toyota TF109, as the Italian firm geared up to its
return to Formula One.
The Jerez circuit, which contains some slow corners as well as medium to fast bends,
puts particular emphasis on the rear tyres, which have to work hard to provide traction
over a wide range of speeds. Though Jerez does not result in especially high top speeds,
every aspect of car’s performance is comprehensively tested there.
The cars will run between 0900 and 1700 on Thursday, Friday, Saturday and Sunday.
Temperatures are expected to range between five and 20 degrees centigrade, according
to current forecasts.
