MEDIUM AND SOFT P ZERO TYRES ONCE MORE FOR ABU DHABI
Milan, October 28, 2013 – The Abu Dhabi Grand Prix is the only race of the year that starts in the late afternoon and ends in the twilight of the evening, providing the drivers and teams with a unique challenge and the audience with a breath-taking spectacle.
The tyres for the Abu Dhabi Grand Prix will be the P Zero White medium and P Zero Yellow soft: the same nomination that was made for India last weekend. The temperature range that the tyres will experience this weekend though is very different, as unlike most other races track temperature falls as the grand prix goes on in Abu Dhabi, rather than rises.
Paul Hembery: “The way that the track temperature falls in Abu Dhabi obviously has an effect on both wear and degradation, meaning that teams are able to do longer runs even on the softer compound later in the race. There are some important implications for strategy here, which means that it’s often possible to try something different in Abu Dhabi than you would in other places, which might well pay off at the end of the race. As a company, Abu Dhabi is a circuit that we know very well because it’s where we did some testing before we started in Formula One. It’s also where the Formula One teams got to sample our tyres for the first time, back at the end of 2010. When it comes to the actual venue, Yas Marina is one of the most modern and spectacular circuits of the year with a number of different technical challenges that test most aspects of a tyre’s overall performance. Tyre wear and degradation isn’t especially high here: last year, when we also nominated the medium and soft, most drivers just stopped once. As the compounds are generally softer this year we’d expect two stops this time, although it’s quite possible that some teams might try just one. We will have to wait for the Friday running until we have a clearer picture of the time difference between the two compounds but overall we’d anticipate race pace among the frontrunners to be reasonably closely balanced, and it’s always under these circumstances that having the right strategy can really make a significant difference. Although there’s quite a high degree of track evolution, and conditions in free practice aren’t always representative of the race, the work done during the Friday and Saturday sessions will be instrumental in shaping each team’s understanding of which strategies are both possible and advantageous on Sunday.”
Jean Alesi: “Abu Dhabi is not a track I have raced on myself, so it’s hard to comment from a driver’s perspective, but it certainly looks spectacular to watch and it’s fantastic to see so much infrastructure invested in Formula One. The only negative impression I had of the circuit initially was that it seemed quite difficult to overtake on sometimes, but I think that this issue has been addressed now and it is also interesting these days to see how the drivers use strategy to gain track position. I’m sure that pit stops will be important this weekend in Abu Dhabi as well. This doesn’t look like a race that will be particularly hard on tyres, but the circumstances are a little bit different from usual, with the race taking place late in the afternoon, so it’s quite hard to predict what’s going to happen. I’ve had some experience of racing in the twilight and the dark from Le Mans and it’s really not easy, but I think it’s probably easier in a Formula One car than in an endurance car, as Formula One cars don’t have headlights. The headlights make it quite hard to judge perspectives – particularly if you’re being overtaken – so it’s better to just have lights on the circuit, like Singapore and Abu Dhabi.”
The circuit from a tyre point of view:
On average the track temperature drops by 15 degrees during the race, falling from around 45 degrees at the start to 30 degrees at the end: which is normally about the same as ambient temperature. This is the opposite to what is seen at most hot races taking place in the early afternoon, where track temperature tends to remain higher than ambient temperature.
A bit like Suzuka, the first part of the circuit essentially consists of a continuous series of bends, which subject the car to lateral acceleration forces of 4g. The tyres then have to deliver optimal performance down a long straight, with the cars on full throttle for around 15 seconds, which equates to a downforce loading of approximately 800 kilogrammes pushing down on all four wheels.
Traction is the key aspect to a strong performance at Yas Marina, as there are not so many high-speed corners. To help the drivers gain maximum traction, the engineers tend to set up the cars with quite a soft rear end, but this can lead to increased rear tyre wear. If the set-up is too stiff at the back the opposite problem can occur: excessive wheelspin, which also takes life out of the tyres.

Technical tyre notes:
The Yas Marina circuit is located at sea level, with the higher air density boosting engine performance. This extra power also has an effect on tyre wear, with more demands being placed on the rear tyres in particular. The cars tend to run a medium downforce set-up, as Abu Dhabi is all about technical compromises.
The track surface in Abu Dhabi consists of stone quarried in England and is generally quite smooth. As more rubber is laid down there is a high degree of track evolution over the course of the weekend and it’s also common to find dust on the circuit during the early sessions, which is quickly swept away.
The top two finishers in Abu Dhabi last year (Kimi Raikkonen and Fernando Alonso) used a one-stop strategy, starting on the soft and ending on the medium. Sebastian Vettel, who started from the pit lane after having his qualifying times disallowed, eventually finished third with a two-stop strategy, having started on the medium and finishing with two stints on the soft tyre.
The tyre choices so far:

Meet the Pirelli F1 Team: Federica Marini, catering manager
Last week we profiled Fabrizio the chef, who thanked his devoted army of catering workers, and this week we meet catering manager Federica. She grew up in Pescara, central Italy, until she was 18 when she went off to study in Rimini. Federica obtained a degree in economics and business, specialising in tourism, “so as you can see, my studies turned out to be not particularly relevant to what I’m doing at the moment!” she jokes. In fact, her plan was actually to become an accountant and she only got into motorsport by chance. Federica helped out at a GP2 race a few years back, covering for someone else at short notice. She enjoyed it, and so continued to work in GP2 while she was studying. Afterwards, perhaps predictably, Federica decided that motorsport was more interesting than accountancy, and off she went to travel the world. But it’s no holiday: at the start of the grand prix weekend Federica helps with the set-up of the motorhome facilities as well as the shopping. Then once the action gets underway she can be found at the front of house, serving lunch and dinner to Pirelli’s personnel and guests. She’s up early every day to be at the circuit by 8am at the latest and she’s among the last to leave as the hospitality team cleans up after dinner. “There’s always an adventure in this job: some good and some bad!” she adds. Maybe that’s why she likes to de-stress completely away from the races. “I love spending my free time with a good book, in silence,” Federica concludes. “And of course like many women, I’m slightly addicted to shopping…” By which we assume she means for clothes this time, rather than food.
