Pirelli continue with aggressive tyre choice - F1technical.net

Pirelli have decided to bring the same tyres to Abu Dhabi as those raced at the Indian Grand Prix, where they provided for a number of interesting pitstop strategies.
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.
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", says Paul Hembery, Pirelli's motorsport director.
"There are some important implications for strategy here, which means that itís 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 itís where we did some testing before we started in Formula One. Itís 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 tyreís overall performance. Tyre wear and degradation isnít 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 weíd expect two stops this time, although itís 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 weíd anticipate race pace among the frontrunners to be reasonably closely balanced, and itís always under these circumstances that having the right strategy can really make a significant difference. Although thereís quite a high degree of track evolution, and conditions in free practice arenít always representative of the race, the work done during the Friday and Saturday sessions will be instrumental in shaping each teamís understanding of which strategies are both possible and advantageous on Sunday."
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 itís also common to find dust on the circuit during the early sessions, which is quickly swept away.
