The stated aim of the new rules is to introduce lighter, more responsive cars, increased emphasis on driver skill, relevant technologies, reduced cost, to make it easier for new manufacturers to enter F1 and to continue with the sport's commitment to reducing emissions.
The published proposals can be seen as a kind of middle ground between Ben Sulayem's initial stance, the desire of at least some manufacturers to keep turbos and a significant hybrid element, and a recognition that the latest rules were flawed in concept and execution.
Both have since tempered their criticisms having seen that the sport's bosses have listened to their comments on the engines and made immediate changes to the rules this year as well as started working towards a new direction in the future.
An FIA spokesperson declined to comment on or discuss the document, pointing instead to an Instagram post published on Ben Sulayem's account outlining the aims and objectives of of the new rules., external It makes no mention of turbos or hybrid technology.
The plan, which comes after initial discussions with individual engine manufacturers on a one-to-one basis, proposes cheaper, lighter, simpler engines with a more visceral sound.
The addition of the turbo satisfies the need for the engines to be road-relevant, as well as increasing efficiency and requiring less fuel than a pure naturally aspirated engine.
However, insiders say the manufacturers are all aligned on wanting to design and build their own power-units and for engines to remain a performance differentiator.
Discussions around the budget cap also involve the need to balance ongoing development of the existing engines with design and construction of the new ones.
The new engines will have none of the problems of energy starvation about which drivers have complained this season.
However, the details around how the rules operate will need discussion.
