FIA president Mohammed Ben Sulayem has confirmed Formula One will switch from its current V6 hybrid engines to simpler, louder V8s by 2031, or possibly as early as 2030.
Speaking to reporters at the Miami Grand Prix, Ben Sulayem said the move is inevitable and aims to reduce complexity, improve sound, and address driver safety concerns related to the hybrid system's energy recovery. Current V6s require drivers to "lift and coast" into high-speed corners to recharge batteries, raising safety issues.
Under current rules, the FIA can force the change for 2031 without manufacturer approval. A supermajority of four out of six power unit manufacturers, including General Motors for Cadillac, could accelerate the switch to 2030. Ben Sulayem confirmed V10s are not feasible, while V8s remain the most popular option, featuring in many road cars. The new power units will use sustainable fuel with minimal electrification.
Formula One previously used V8 engines from 2006 to 2013, before transitioning to the current V6 turbo hybrid era.
