FIA proposes turbo-hybrid V8 engines for next Formula 1 rules

Formula 1's next engine regulations could centre on turbo-hybrid V8 power units under a proposal the FIA has circulated to manufacturers, BBC Sport reported. The document sets out a framework for engines to be introduced in 2030 or 2031, rather than a completed set of rules. BBC Sport said multiple sources within the championship had supplied details of the proposals.

Watch the highlights:

The framework follows individual discussions with engine manufacturers and targets lower costs, reduced weight and simpler technology. Its stated objectives also include more responsive cars, a greater emphasis on driver skill and an easier route into the championship for new manufacturers. The proposal retains hybrid technology and turbocharging while seeking to maintain Formula 1's commitment to reducing emissions. It moves away from FIA president Mohammed Ben Sulayem's earlier push for naturally aspirated engines.

Two approaches to development are outlined. One would limit the changes manufacturers need to make to their existing designs. BBC Sport reported that a 2.1-litre V8 could be created by adding two cylinders to the current 1.6-litre architecture while reducing the size of the turbo and hybrid motor. The alternative would involve an outside supplier developing a substantially standardised base power unit, which individual manufacturers could then customise.

That second route faces resistance. According to the report, manufacturers want to continue designing and building their own engines, with performance differences remaining part of the competition. Mercedes, Ferrari, Audi, Honda and Red Bull currently supply Formula 1 teams. Cadillac, which entered the championship with its own team this year, plans to build an engine for the next regulations. The report described the broad engine architecture as essentially acceptable to manufacturers, while stressing that operational details still require negotiation.

Cost controls are another unresolved issue. The document proposes halving the current annual engine budget cap of $190 million, but BBC Sport characterised that figure as an opening position for discussions. Manufacturers also face the challenge of managing workforce implications and funding continued development of the current engines alongside work on their replacements. Those considerations are linked to the choice between a 2030 and 2031 introduction.

Discussions over the coming weeks are intended to produce a proposal for the FIA world council in December. An FIA spokesperson declined to discuss the document with BBC Sport, referring instead to a social-media post outlining the objectives of the next rules. That post did not specify turbocharging or hybrid technology, leaving the detailed framework reported by the BBC subject to further talks.
