The FIA and Formula 1 manufacturers remain divided over engine regulations set to take effect in 2031. President Mohammed Ben Sulayem advocates a naturally aspirated V8 with limited hybrid elements, while several car makers favour turbocharged units aligned with road-car technology.
The debate centres on balancing racing spectacle with technological relevance to production vehicles. Ben Sulayem wants engines that prioritise noise and simplicity, targeting a return to V8 power supplemented by a small kinetic energy recovery system.
Manufacturers are split. Mercedes and Audi prefer turbocharged designs for efficiency and road-car connections, while Ferrari, Cadillac and Red Bull-Ford Powertrains remain open to the FIA proposal. Honda is also involved in the discussions.
Weight reduction is another key goal. The FIA aims to bring car weight down to around 700 kg, potentially through smaller batteries and the return of in-race refuelling, which has been banned since 2009. Logistical and sustainability concerns, however, complicate that option.
Noise levels and audience appeal add further complexity. About half of current fans are under 35 and have never experienced high-revving V8 engines at a live event.
