SUNSHINE AND RAIN: PIRELLI ENDS ITS TEST CAMPAIGN FOR 2011 F1 SEASON

Pirelli started its build-up to Formula One this year with a preliminary test at the Italian circuit of Mugello on 19 August 2010, held in ambient temperatures that peaked at 27 degrees centigrade (with 35 degrees track temperature). The 2011 testing campaign ended seven months later at a rain-lashed Barcelona circuit in Spain, with just 13 degrees on Saturday.

The testing adventure also took Pirelli to Monza, Valencia, Jerez, Le Castellet, Bahrain and Abu Dhabi, covering nearly 100,000 kilometres – the equivalent of more than 300 grand prix – in five countries.

The final test in Barcelona, arranged at short notice after the Bahrain Grand Prix did not take place as the season-opener, covered five days, with each of the teams running for four days each. Weather conditions were dry over the opening four days in northern Spain, with ambient temperatures peaking at 27 degrees centigrade on Thursday, but on Saturday the four teams that were still testing – Ferrari, McLaren, Mercedes and Williams – experienced heavy rain for the first time, with 10 millimetres of water soaking the track in the morning. In fact, conditions were too wet for any constructive running to take place on the final day, with the four teams completing only a total of 101 laps. With deep standing water on the straights, conditions were extremely difficult for the five drivers who took to the track.

During the five days of the Barcelona test, the teams completed a total of 3555 laps, equaling approximately 16,548 kilometres. The team covering the most distance was Sauber, which racked up 390 laps or 1815 kilometres in four days. The fastest time of the test was posted by Michael Schumacher (Mercedes), who set a time of 1m21.268s on Friday, comfortably eclipsing the benchmark of 1m22.625s established by Felipe Massa (Ferrari) at the previous Barcelona test last month. The team with the most wet-weather experience is also Mercedes, which completed 40 laps today in soaking conditions.

Pirelli’s Motorsport Director Paul Hembery said: “It’s certainly been a very interesting five days, where we’ve experienced a huge variety of weather conditions. We had a brief window of optimal conditions in the afternoon during the week, where temperatures were finally high enough for our hard and soft compound rubber to come into its ideal operating range. This enabled a number of the teams to carry out race simulations, which revealed some interesting data. Then on Saturday, we had a deluge – but the conditions were really too wet then for the four teams present to learn anything significant. What we have seen over the course of the test, particularly during the race simulations, is a wide variety of strategies, which promises an exciting season ahead. During the previous test in Barcelona, we calculated from the race simulations that there were 54 potential overtaking opportunities – and that was without all the cars present. Australia is sure to be very different to Barcelona, but now we’re just looking forward to getting started.” The Australian Grand Prix, which marks Pirelli’s return to Formula One for the first time in 20 years, takes place on March 27 at Albert Park in Melbourne.

F1: Pirelli concludes the first Official Tyre Test

Each team today completed an average of 80 laps and 5500 kilometres on the Yas Marina circuit (Abu Dhabi), adding to the total of 5000 kilometres run yesterday, to conclude the first official tyre test for Pirelli: the exclusive Formula One tyre supplier from next year.

A total of 15 drivers were on track today: one per team apart from Force India, McLaren and Sauber, which used two drivers. As was the case yesterday the test started at 0900 and finished at 1700.
Each car had four sets of tyres at its disposal, two medium-compound sets and two softcompound sets.

The teams were backed up throughout the tests by Pirelli’s engineers and technicians. The Italian company put a dedicated engineer at the disposal of each team, in order to collect data and opinions that will be discussed with the teams and drivers. At the end of the day there was a final briefing between the teams and Pirelli to share information and focus more closely on some of the data that had been obtained. Pedro de la Rosa – one of Pirelli’s drivers in private testing along with Nick Heidfeld and Romain Grosjean – was also present to support Pirelli’s F1 squad. De la Rosa visited all the teams today to get the first impressions from the drivers and their individual opinions.

Paul Hembery, Pirelli’s motorsport director, commented: “It was hard work, but a very positive and educational experience for us. We know that this was only our first test, but we think that we’ve passed it with full marks. The comments from the drivers are very encouraging: they especially enjoyed the performance of our front tyre, which is an area that we have worked on considerably. This was one of our objectives, and I’m delighted that we have hit our target. Throughout these two days we’ve tried out the medium and soft compound tyres and we’ve had good results from both of them, particularly in terms of wear rate. During the two days of testing here in Abu Dhabi we’ve racked up nearly 11,000 kilometres with all the teams: that’s more than we have accumulated in three months of private testing.

Pirelli’s testing programme will now continue at the start of December. The next private tests are scheduled to take place in Bahrain from 12-16 December, where Pirelli’s engineers will once more try out the various compounds in hot conditions. There will be another private test session in Europe during January, before all the teams reconvene at the beginning of February for the first official test.
