FIA proposes turbo-hybrid V8s for next F1 engine rules

The FIA has sent six Formula 1 manufacturers a framework for the next engine rules, proposing turbo-hybrid V8s that could be introduced in 2030 or 2031. It is a proposal for discussion, not a settled rulebook, and sets out more than one way to build the power units.

The move follows criticism of F1’s current engines for their complexity and for the way their design and operation have diminished the challenge of some of the sport’s best corners. The proposed architecture would move from today’s 1.6-litre V6 turbos to a 2.0-2.3-litre V8 with a smaller turbo running at reduced boost and a less powerful hybrid system. The FIA has moved away from an earlier naturally aspirated direction: turbocharging is intended to preserve road relevance, improve efficiency and use less fuel than a naturally aspirated engine.

The electric motor’s recovery capacity would be 200kW, compared with 350kW under the current rules. The proposal would make 100kW available at all times and reserve a further 100kW for push-to-pass or overtaking. Overall output is envisaged at around 900bhp, with the power units continuing to use fully sustainable fuels.

The stated aims are lighter, more responsive cars, a greater role for driver skill and lower costs. The document targets an 80kg reduction in overall car weight and proposes halving the annual engine budget cap from its current $190m. The proposed cut is a starting point for discussion. Talks also need to find a suitable phase-in to help teams manage workforce effects, while balancing continued development of existing engines with the design and construction of the new ones.

The FIA document lays out two ways to develop the units. One would minimise changes by adding two cylinders to current 1.6-litre blocks to make a 2.1-litre V8, while reducing the turbo and MGU-K. The more controversial alternative would have an outside manufacturer design and supply a standardised baseline power unit for manufacturers to customise. F1 insiders say manufacturers favour designing and building their own engines, keeping them as a performance differentiator.

The basic architecture is said to be broadly acceptable to all manufacturers, but the rules’ operating details remain open. Discussions over the coming weeks aim to produce a proposal for the FIA World Council in December.
