Should F1 change this controversial rule for 2027?

The proposal to alter the power unit split from 50/50 between internal combustion and electrical power to a 60/40 division for the 2027 F1 season currently hangs in the balance.

The move had looked near certain to go ahead, but Audi and Ferrari have emerged as dissenting voices in recent days, with the subject being a major talking point over the Canadian Grand Prix weekend.

The change would be facilitated by increasing fuel flow into the power units to remedy some of the more-maligned and unintended idiosyncrasies of the new F1 regulations.

However, that would potentially necessitate chassis changes for some teams, with the need for larger fuel tanks a byproduct of the decision.

Mercedes HPP, Red Bull Powertrains and Honda are believed to all be in favour, but with ratification requiring a super majority of votes — which is four of the five power unit manufacturers plus F1 and the FIA — amongst the Power Unit Advisory Committee, getting the proposal over the line has turned into an uphill battle.

Carlos Sainz wants to see F1 and the FIA take an aggressive approach to the negotiations, but whether the championship and its governing body can convince Audi and Ferrari remains to be seen.
