Pirelli have denied their Barcelona tyre test favoured Mercedes over the other Formula 1 teams, reiterating that the rubber used was their 2014 compound.

The controversy which swept through the Monaco paddock last Sunday morning has overshadowed Nico Rosberg's victory in Monte Carlo after it emerged the Silver Arrows had completed 1000km of testing over three days following the Spanish GP.

In a statement released on Friday, the Italian manufacturer said: 'Pirelli, in development testing with teams carried out in 2013, has not favoured any teams and, as always, acted professionally, with transparency and in absolute good faith.

'The tyres used were not from the current championship but belonged to a range of products still being developed in view of an eventual renewal of the supply contract. Further, none of the tests were carried for the purpose of enhancing specific cars, but only to test tyre solutions for future championships.

'The use of the car utilised by Mercedes, in particular, was the result of direct communication between FIA and the team itself. Pirelli did not ask in any way that a 2013 car be used: not of Mercedes nor FIA nor the teams which, during the year, were offered the opportunity of participating in tests for the development of tyres for 2014.

'With regard to the rules which govern its conduct, the company has always respected the contractual limits which bind it to the FIA, teams and championship's organizers, and has always respected the principles of sporting loyalty.

'The tests were conducted in observance of the contract between Pirelli and FIA, which gives the supplier the possibility of carrying out tests for the development of tyres with each team of up to 1,000 kilometres, without specifying the type of car to be used, nor sanctioning the simultaneous presence of all the teams for the running of the tests.

'In this regard, Pirelli has since 2010 made it clear that it is neither possible nor useful to carry out this type of test with all the teams simultaneously. In fact, this type of testing aimed at technological development and researching new solutions, involves many tyres of different types which must be tested with a single car at a time.

'Already in March 2012, Pirelli sent an email to all the teams, FIA and FOM, inviting the teams to indicate their availability for testing for the development of tyres for 2013. Further, the company explained that it was necessary to conduct the tests with the teams' cars because it did not have a suitable one of its own (Pirelli has the use of an adapted 2010 Renault and, before that, a 2009 Toyota).

'The invitation was subsequently repeated in various official contexts and repeated to some teams last March for the development of tyres for 2014.

'This test, as always, carried out with a single compound never used in a championship, regarded structures not in use in the current season and not destined to be used later during the 2013 season. The tyre tests were conducted "in the dark", which means that the teams had no information on which specifications were being tested or about the goal of the testing; nor did they receive any type of information afterwards.

'Further, the tests did not regard delamination in any way, as that problem was dealt with and resolved by Pirelli's technicians through laboratory tests, with the support of data gathered during the first races of the season.

'Pirelli always asked for representative cars, that is, with performances comparable to those of the cars being used in the championship underway, without ever referring to those effectively used in the 2013 races.

'The Barcelona test was conducted in cooperation with Mercedes between May 15 and May 17, 2013. The teams made available one car and two first tier drivers, who alternated at the wheel on different days.

'The trials were done with a base compound, not in use this year, and 12 different structures which had never been used in 2013, only one of which with Kevlar. The team did not obtain any advantage with regard to knowledge of the behaviour of the tyres in use in the current championship.

'The type of car used during the tests was the subject of direct discussions between Mercedes and FIA, as shown in the exchange of emails between the team and Pirelli. In particular, Mercedes informed Pirelli that its 2011 car could not be used and that it had already contacted FIA regarding the use of the 2013 car.

'There is no doubt that the questions relating to the vehicle were the exclusive domain of the team and that Pirelli was excluded from these questions (notwithstanding Pirelli's need, from a technical point of view, to have a representative car in terms of impact on the performance of the tyres).

'To confirm that this was an ordinary development test and not aimed at specific interventions, Pirelli made no specific requests about the drivers or about the tyre of Mercedes staff that would be present during the tests and had fielded its normal team for development testing.'
