F1, will it be 60:40 in 2027?
In early May, FIA and FOM announced that they had reached an agreement with F1 teams and engine manufacturers to introduce changes for 2027, which would bring the ratio between thermal and electric propulsion from the current 54:46 to 60:40. In the following weeks, however, some concerns emerged from the engine manufacturers (Audi and Ferrari in particular) and discussions intensified on the most delicate points, namely the potential increase in costs and the weakening of the ADUO mechanism – having to design a new power unit.

Compromise advances to convince Ferrari
As reported by Auto, Motor und Sport, the Monaco weekend should be the right one to find a meeting point that can convince the two engine manufacturers currently most perplexed about the issue, namely Audi and Ferrari.
The original proposal from the FIA aimed to increase fuel flow by 13%, with the goal of providing the thermal engine with an additional 68 hp, while simultaneously reducing the electric one by 50 kW.
The path to compromise would be, according to the German website, a 5% increase in fuel flow, sufficient to significantly reduce lift and coast and clipping. Furthermore, Audi argues that the aerodynamic changes floated for 2027 – there is talk of a 10% reduction in downforce – would greatly help achieve the set goal.
This way, new engines would not be necessary (so the ADUO would continue as set at the beginning of 2026) and new chassis would not be needed (another sticking point).
June 14 is the deadline for the final approval of the 2027 changes – with a qualified majority of 4 out of 6 votes from the engine committee – which is why Stefano Domenicali and Mohammed Ben Sulayem are pushing for a positive resolution to the dispute.
