Formula 1, the FIA and the sport's teams have agreed to delay the publication of the final 2021 sporting, technical and financial regulations until the end of October following a summit held in Paris on Thursday.
In a meeting before last week's Canadian Grand Prix in Montreal , the teams had given their approval on a large part of the future regulation platform.
However, several crucial aspects of the proposal remained a source of contention, requiring further discussion and refinement.
In conformity with its Sporting Code, the FIA needed to set the rules in stone by the end of June, or 18 months before their introduction on January 1 2021, with only a unanimous agreement by the teams allowing for a delay.
In Thursday's meeting in Paris, which also included F1 tyre supplier Pirelli and driver representatives Lewis Hamilton, Nico Hulkenberg and GPDA chairman Alex Wurz, a consensus was reached among the teams to postpone the finalization of the regulations until October.
However, it appears that to prevent the larger outfits of executing a U-turn between now and the end of October on a series of financial provisions that have been agreed upon, all teams have signed a letter guaranteeing that budget cap and financial rules will not be subject to change.
Formula 1 issued the following statement confirming the extension of the regulation deadline:
"While the FIA Formula 1 World Championship’s key stakeholders feel the core objectives outlined for the future set of regulations have been defined, in the interests of the sport it was agreed that the best outcome will be achieved by using the extra time for further refinement and additional consultation.
"Furthermore, following today’s first meeting featuring the aforementioned stakeholders, a series of additional meetings will be held over the coming months."
While drivers have taken part in consultations with F1 in the past, Hamilton, Hulkenberg and Wurz's presence in Paris was a clear indication of the group's will to add its voice to the debate.
"We try to indicate what we want," said Max Verstappen in Canada, as quoted by Motorsport.com.
"I think that this has also given us wider cars and more speed. But we don't agree with how the downforce is generated. So we are trying to give feedback on that."
