Benson forecasts V8-turbo F1 formula for 2030 or 2031

Formula 1 could move to a new engine formula in 2030 or 2031 featuring turbocharged V8s and 15–25% electrical power, used mainly to assist overtaking, BBC F1 correspondent Andrew Benson forecasts.

Benson outlined the possibility in a Q&A ahead of the Singapore Grand Prix. He says F1’s leaders are aware that the latest rules have caused energy-starvation problems. In the formula he envisages, drivers would be able to use maximum power all the time, with the electrical elements helping them overtake.

Benson presents the outline as a forecast, not a confirmed change to the regulations. It would differ from the naturally aspirated, non-hybrid engines Max Verstappen, Fernando Alonso and Lando Norris have advocated in 2026. FIA president Mohammed Ben Sulayem has also pushed for naturally aspirated engines: V10s in early 2025 and, more recently, V8s, Benson says.

Benson cites higher fuel use and noise as drawbacks to naturally aspirated engines. He says their noise could put races near population centres, including Miami and Las Vegas, at risk, while F1 is trying to reach net-zero carbon by 2030. He also notes that most road-car engines are turbocharged and have some degree of hybridisation.
