The teams are still working on the RRA
Despite the departure of Red Bull, Ferrari, and Sauber from FOTA, the top teams are still negotiating around the RRA to find a solution.

The leaders of the Red Bull, Ferrari, McLaren, and Mercedes AMG teams met yesterday, Monday, to try to resolve their differences regarding the RRA (Resource Restriction Agreement) which manages the limitation of expenses in Formula 1.
No member present at this meeting wished to make any comments, but according to Autosport, the discussions were reportedly conducted positively, even though further meetings should be scheduled to reach a final agreement.
Ferrari and Red Bull, in particular, announced a few days ago their intention to leave FOTA while specifying that they remain committed to seeking an agreement regarding the RRA. They demonstrate this by participating in negotiations outside of FOTA.
Christian Horner believes that an agreement could be reached, but the RRA must manage the entirety of the car—and particularly the engine as he proposed several days ago.
« We need it to include all aspects of the car. Managing equivalences is always something dangerous. Each team has different management, different owners, » Christian Horner confided.
Certain things belong to car manufacturers and others are independent, and if you look at what works, like testing, hours spent in the wind tunnel, and staff reductions, the things you can see and feel work well. But as soon as you start talking about work equivalence against outsourcing hours, that’s where there seem to be some difficulties.
The director of the Red Bull Racing team was keen to remind that all teams, and particularly the most significant ones that almost reach the set limits, hope to reach an agreement on this point.
There is a willingness from all teams to try to control costs, it’s simply the way of doing it (that differs). And you cannot exclude the engine from this because some teams produce their own engine, so it is important to look at the team as a whole rather than just focusing on the chassis, added Horner.
