ABU DHABI, United Arab Emirates (AP) Mercedes has demanded clarification from Formula One authorities on rules restricting aerodynamic testing and preventing collusion between rival teams.
Mercedes representatives met stewards on Saturday before qualifying at the Abu Dhabi Grand Prix.
The legal documents provided to the media made no direct allegation of wrongdoing against any team, but the dispute is widely seen as a reaction to the close relationship between Ferrari and the U.S.-based Haas team which will enter F1 next season.
Wind-tunnel usage is restricted to current competitors under F1 rules, but Ferrari has been giving Haas access to its facility for testing, leading to concerns that both teams have benefited from the data produced.
Ferrari team principal Maurizio Arrivabene said the team had no concerns about Mercedes' actions or potential outcomes.
''They were asking a question and everybody has the right to talk about that and to give information to the stewards,'' Arrivabene said to Sky Sports. ''Concerning Haas, we were and we are transparent. We gave all our information to the FIA in the past, as we do in the present.''
A statement from stewards said they would ''endeavor to hand down their decision on the specific matters prior to the start of the race on Sunday.''
