FIA AND TEAMS DEBATE 2031 ENGINE FUTURE
Formula 1 is already looking beyond the current engine rules, with early discussions taking place between the FIA and manufacturers about what the 2031 regulations could look like. The talks are still informal, but they are already revealing major differences in vision between the governing body and some teams.
The FIA is reportedly pushing for a return to simpler engines, with a naturally aspirated V8 concept combined with a small hybrid system similar to KERS. The idea is to reduce complexity, cost, and weight, while keeping a basic level of electrification. This direction also fits a wider goal of making future F1 cars lighter and closer to a target weight of around 700 kg.
One of the key ideas being discussed alongside the new engine formula is the possible return of refueling during races. According to the concept, smaller fuel tanks would be used if refueling is allowed again. This would further reduce car size and weight, making the cars more compact and potentially improving race strategy variation.
However, there is no agreement yet among manufacturers. Mercedes and Audi are reported to prefer keeping turbocharged engines, arguing that turbo technology is more efficient and closer to road car development. This creates a clear split between teams that want a return to naturally aspirated engines and those that want to keep turbo hybrid concepts.
Recent reporting and statements from FIA president Mohammed Ben Sulayem have supported the idea of moving toward V8 engines in the long term, with the 2030–2031 period seen as the earliest realistic window for any major change. The current V6 turbo hybrid era is still set to continue under the 2026 regulations, meaning any decision about refueling and engine format remains far away and highly dependent on manufacturer agreement.
