PIRELLI PUTS THE ACCENT ON STRATEGY IN AUSTRALIA

Pirelli’s 2012-specification tyres delivered on their promise to provide a greater variety of race strategies by decreasing the performance gaps between the compounds this year. The new versions of the P Zero Yellow soft and P Zero White medium were nominated for the Australian Grand Prix, but the drivers had very little dry running with them before the start, as Friday’s free practice sessions in Albert Park were characterised by rain.

The top finishers adopted a two-stop strategy for the race, as was the case last year, but with the pace of the medium and the soft compound only differing by around 0.5 seconds per lap, the way in which they used the tyres was different – with some drivers favouring two stints on the soft tyre and others preferring two stints on the medium.

One of the turning points of the race was a safety car on lap 36, which bunched up the field and allowed Red Bull Racing’s Sebastian Vettel to claim second place by passing McLaren driver Lewis Hamilton in the pits.

At the restart, race leader Jenson Button demonstrated the rapid warm-up time of the medium compound even in the cool conditions of the afternoon by pulling out a second within the first sector, to eventually claim his third victory in Australia. Vettel, who finished runner-up, had adopted a completely different strategy by using the soft tyre during his medium stint. Last year, Vettel’s winning margin was 22 seconds; this year Button won by just over two seconds.

Pirelli’s motorsport director Paul Hembery commented: “The Australian Grand Prix certainly lived up to expectations, and we fulfilled our objective of providing scope for more strategies by reducing the performance gaps between the compounds and extending the window of peak performance. An interesting element was that there were many pit stops that were not for wear level but instead for degradation, confirming what we wanted to achieve strategy-wise. We also saw more use of the medium tyre than the soft tyre, contrary to last year. Despite this range of strategies there were some very tight battles all the way down the field right up to a dramatic final lap, with one driver crashing out and eighth, ninth and 10th places crossing the finish line practically together! The wear and degradation of the tyres was around 0.1 seconds per lap on the soft tyre – with the frontrunners choosing to pit twice, despite the rapid pace at the front of the field. Many congratulations to Jenson Button and McLaren for a stylish victory and also to Mark Webber, who scores his best-ever finish on home territory.”

FORMULA 1 TYRES TAKE TO THE TRACK AT JEREZ

The Formula 1 World Championship is warming up its engines at Jerez, Spain, where the teams are taking part in a test session from 7-10 February, trying out the new Pirelli tyres. Each car will have available to it the soft, medium and hard variants, as well as wet weather and slick tyres.

In the improbable eventuality of rain at Jerez over the next few days, drivers will also be able to count on the return of the historic Cinturato.

The teams have available to them a maximum of 100 sets of tyres for the tests and can, as part of that quantity, choose which tread compounds to adopt during the four days.

This will be the session when drivers will try out the ‘squarer’ profiles which, as announced in Abu Dhabi, will ensure extremely high performance and last longer but without renouncing spectacle. The Jerez circuit has many variants, especially ample fast and slow corners, enabling the teams to sample their tyres in the various driving conditions.

The new Pirelli P Zero Silver, the first road car tyre derived from Formula 1 technology, will be presented at Jerez simultaneously.
