Pirelli Malaysian Grand Prix Preview

The toughest compound in Pirelli’s new 2013 range of tyres makes its debut in Malaysia, complete with a brand new color. The P Zero Orange hard has been nominated for Sepang together with the P Zero White medium, which was already seen in Australia.

The two hardest compounds in Pirelli’s range are ideal for the extreme temperatures and abrasive surface of Malaysia. Sepang is also well-known for its monsoon-like downpours, which make it extremely likely that the Cinturato Green intermediate and Cinturato Blue full wet tyres will be seen at some point over the course of the weekend.

Pirelli’s motorsport director says:
Paul Hembery: “We would describe Sepang as genuinely ‘extreme’: both in terms of weather and track surface. This means that it is one of the most demanding weekends for our tyres that we experience all year. For the first time we see our new Orange hard compound in competition, with this color chosen to make it more easy to distinguish from the white medium on television. The nomination we have for Malaysia is the same as last year, but the compounds themselves offer more performance and deliberately increased degradation this season, Last year three stops proved to be the winning strategy in a mixed wet and dry race, with a thrilling finish between Fernando Alonso and Sergio Perez that was all about tyres. We’d expect three stops again but once more it’s likely to be weather that dominates the action. Even when it isn’t raining, the drivers can expect humidity in the region of 80% and ambient temperatures of more than 30 degrees centigrade.”

The tyre from a circuit point of view:
    •    Malaysia is one of the more abrasive surfaces that the cars compete on all year, which is part of the reason why the two hardest compounds from the range have been nominated.
    •    The P Zero Orange hard tyre has a high working range, whereas the P Zero White medium has a low working range. This makes it an ideal combination that can deal well with any eventuality. The durability characteristics of the new hard tyre are close to those of last year’s medium tyre, resulting in lap times that are around 0.4s-0.5s quicker than the 2012-specification hard.
    •    The Sepang track is built on what was formerly a swamp, with a fundamentally uneven surface. However, the asphalt was resurfaced in 2007, which smoothed out most of the bumps – although some remain.
    •    Last year, the hard and medium compounds were also chosen for the Malaysian Grand Prix. The top five drivers adopted a three-stop strategy: intermediate-wet-intermediate-slick. Bruno Senna meanwhile, in fifth place, stopped four times.

Technical tyre notes:
    •    Malaysia places heavy lateral demands on the tyres; it’s the second-highest lateral load of the year after Barcelona. This can lead to heat build-up within the tyre, which can reach a maximum of 130 degrees centigrade.
    •    Sessions at the Malaysian Grand Prix in the past have been frequently interrupted by heavy rain, and the race was even halted early in 2009, with half-points being awarded. Pirelli has a new specification of Cinturato Green intermediate and Cinturato Blue full wet tyre this year; with a redesigned construction to help improve traction and prevent snap oversteer.
    •    Although grip levels are high in Malaysia, the frequent rain has the effect of washing any rubber that has been laid down off the track overnight, meaning that there is often a ‘green’ surface at the start of each session. While a dry line can emerge quickly because of the high ambient temperatures, drainage at Sepang is not particularly good, which can lead to pools of standing water.•    

Meet the Pirelli F1 Team: Mario Isola, Racing Manager
Mario was born and bred in Milan, and at every race this year he is Paul Hembery’s right-hand man. Mario looks after the day-to-day running of Pirelli’s Formula One operations at the circuit and back at base in Milan, liaising with the teams and organizers. Basically Mario is the man that people go to if there is a problem to be solved. He also helps to run all of Pirelli’s 250 other motorsport programs. Mario started off his career as a tyre tester, which gave him a particular sensitivity to the way in which tyres work, and he has also been an engineer in rallying and endurance racing. In his spare time (not that there is much of it) he is a volunteer ambulance driver in Milan and also an amateur rally driver – with some surprisingly good results in the past.
