F1 Engine Future: FIA and Regulators Consider Return to Turbocharged V8s

Formula 1 must decide whether to maintain hybrid electrification or return to naturally aspirated V8 or V10 engines following recent discussions involving drivers and motorsport leadership.

Drivers and Regulators Push for Engine Shift

FIA president Mohammed Ben Sulayem has also advocated for bringing back naturally aspirated engines, initially proposing V10s early last year before shifting focus to V8s. Ben Sulayem cited the evocative sound of V8s and the benefit of lighter cars as primary reasons for the potential rule change. However, naturally aspirated power units consume more fuel, meaning cars would start races carrying heavier fuel loads than they do under current regulations. To offset this, the FIA investigated the possibility of bringing back mid-race refueling, though teams strongly oppose the idea.

Fuel Consumption and Overtaking Statistics

Reintroducing refueling and heavier cars brings distinct competitive and environmental complications for the championship. Statistics indicate that the previous refuelling era from 1994 to 2009 produced the lowest number of on-track overtakes in Formula 1 history. Burning additional fuel conflicts with the sport's target to achieve net-zero carbon status by 2030, even if race fuel consumption accounts for a tiny fraction of the overall footprint. Extremely loud naturally aspirated engines also pose acoustic compliance risks for street races held near major population centers like Miami and Las Vegas.

Manufacturers Demand Road Relevant Turbocharged V8 Engines

Automotive manufacturers invest in Formula 1 primarily for marketing purposes tied to commercial road car development. Because modern production cars predominantly use turbocharged engines with varying degrees of hybridization, manufacturers demand relevant technology in the racing series. Consequently, the sport appears on course to introduce a new engine formula for 2030 or 2031 featuring turbocharged V8s paired with 15% to 25% electrical power. Regulators intend to use this electrical energy primarily as a push-to-pass system, avoiding current energy-starvation issues and allowing drivers maximum power deployment throughout grands prix.
