FIA president Mohammed Ben Sulayem feels F1 should consider returning to the V10 engines but with sustainable fuels.
The 2026 F1 regulations introduce a switch to 100% sustainable fuel to achieve Net Zero Carbon by 2030. The sport will retain the turbocharged 1.6 V6 engine with a more powerful electric component. Audi and Cadillac are set to join due to the shift towards electric energy. Despite hybrid rules encouraging Honda to stay, Renault plans to cease being a works manufacturer in F1. Calls for the V10 engines’ return, backed by FIA’s Ben Sulayem and Stefano Domenicali, point towards a potential shift in F1’s power unit direction. Paddy Lowe of Zero Petroleum notes the challenge of moving away from hybrids due to the efficiency and cost-effectiveness of e-fuels compared to traditional models.
