F1 is set for a critical meeting between its power unit manufacturers over the much-heralded change to the engines for 2027, ApexF1News understands.
Earlier this month, it was announced by the FIA that for next season, a proposed 60:40 split in power output from the engines would be adopted, in a change from the 50:50 split between the internal combustion engine and the beefed-up 350kw batteries.
The idea, agreed in principle prior to the Miami GP was for the ICE to take on an extra 10% of power output and reduce reliance on the batteries after the first three races had shown weaknesses in the rules, with drivers having to lift and coast and super-clip to either save energy or recover it.
Whilst the PUMs on the grid, Audi, Honda, Ferrari, Mercedes HPP, and Red Bull Powertrains are broadly in support of the need to change the power output split, it is understood there is no consensus among them on when this should actually be, with some keen on an immediate change for 2027, whilst others believe it should be for 2028.
It is understood from ApexF1News’s sources, that Audi and Ferrari have differing concerns, with the former having invested heavily in the initial 50:50 ratio split, and is unlikely to want to commit to huge spending again to re-design the engine for 60:40.
Despite producing the class-leading engine for the new rules, it is understood that Mercedes HPP is in favour of the rule changes, whilst struggling Honda are in favour of whatever the FIA decides to do.
Talks are planned across the Canadian Grand Prix weekend in Montreal.
