The FIA has outlined the regulatory changes for Formula 1 power units in 2027, paving the way for a gradual transition to a 60-40 power distribution by 2028. Following intense negotiations, a sensible compromise has been reached that will see a 58% internal combustion and 42% electric split next year.
Rather than jumping straight to the originally proposed 60-40 ratio, logic has prevailed. The fuel flow rate will only increase by 5% in 2027 instead of the requested 13%. The larger increase will be deferred until 2028 when power unit development is strictly frozen.
