The FIA has announced that it wants both Mercedes AND
Ferrari to provide information for a disciplinary inquiry into the recent Pirelli tests carried out in Barcelona.
Mercedes is facing the prospect of being called to appear before the FIA's International Tribunal after it emerged that the team had spent three days testing with Pirelli following the Spanish Grand Prix.
Both Ferrari and Red Bull lodged a protest with stewards in Monaco over the test, which was carried out using the team's 2013 spec car, with the matter being referred to the governing body.
Following the revelation that Mercedes had taken part in the test, it also emerged that Ferrari had been involved in a similar test between the races in Bahrain and Spain, with that test again taking place at Catalunya.
Ferrari's test was carried out using a 2011-spec car run by its Corse Clienti division, leaving the Italian team believing it had acted fully with the regulations that prevent in-season testing – in contrast to Mercedes' decision to run its current machine.
However, despite the apparent belief that teams are free to run two-year old cars in season, Ferrari has now been asked to join Mercedes in providing more information to assist the governing body with its ongoing investigation.
“The FIA has asked Team Mercedes AMG Petronas F1 and Scuderia Ferrari Team which have taken part in tyre tests in the 2013 season to reply to a disciplinary inquiry in pursuance of the FIA Judicial and Disciplinary Rules,” a statement from the governing body read.
“This follows the Stewards' Report from the Monaco Grand Prix and represents supplementary information required by the FIA in the light of the replies received from Pirelli, who were asked for clarifications on Tuesday May 28th.”
Ferrari has yet to respond to the FIA's missive.
