Following an agreement ratified by the FIA World Council, Pirelli will hold a tyre test in Abu Dhabi on Tuesday 1 December, after the final grand prix of the 2015 season. Pirelli requested the Abu Dhabi session in order to develop a new construction for the 2016 slick tyres as well as to test the new Ultrasoft compound, which will form part of the P Zero F1 range next year. The one-day test will take place from 9am-9pm continuously. All teams will attend the test, running one car each, and they will not be allowed to try new parts nor alter the cars in any way during the test. Pirelli will define the test programme for each car. The tyres used during this test will not be considered as part of the testing allocation for 2015 and will not show any branding or colour markings to indicate which tyre set is fitted to each car. A very full testing program is planned due to the limited amount of time available. The full results will not be available until some days after the test is concluded, as all the data from the teams is collected and analysed. For all these reasons Pirelli and the teams have with regret taken the joint decision to keep the test closed to the media. Pirelli will, however, be releasing a full press release at the end of the test.
