According to a statement released by the FIA this evening, the Mercedes and Ferrari F1 teams have been called to supply further information for a disciplinary inquiry over the recent “secret” Pirelli F1 tyre test that took place in Barcelona.

The recent uproar was initially focused around the secret Pirelli test carried out by Mercedes after the news broke during the Monaco Grand Prix weekend.

Ferrari and Red Bull Racing lodged a protest against Mercedes using their current 2013 car in the test at Barcelona immediately after the Spanish Grand Prix. The stewards then referred the matter to the FIA.

It has since emerged that the Corse Clienti, Ferrari’s customer car division provided a 2011 car for a Pirelli tyre test two weeks before the Mercedes test took place.

This evening, the FIA issued a statement saying that the Formula One Governing Body wanted both Mercedes and Ferrari to participate in the investigation surrounding the tyre testing.

Their statement read as follows:

“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,” said the statement.

“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 28.”

It was previously believed that running the tyre tests with a 2011 car was within the rules but it now seems that this could be doubt as it could be argued that the 2011 car is not “substantially different” from the 2013 car as is required by Article 22.1 of the F1 sporting regulations.
