Formula 1 to introduce experimental fuels, power unit cost cap in 2026

The FIA has approved plans for Formula 1 to introduce new power units in 2026 alongside 100% sustainable fuels and cost caps for power units.

The World Motor Sport Council has approved the 2026 Power Unit Regulation, which maintains the 1.6-litre V6 engine, increases electrical power to 350 kW, and eliminates the MGU-H.

A cost cap will be introduced for power units, to encourage new manufacturers and teams to enter the sport.

The 2026 change will also introduce a '100% sustainable fuel' with Formula 1 'engaged in discussions with fuel companies'.

F1 will move to E10 fuel in 2022, before the plan to transition to new models of "sustainable" propulsion from 2026.

It's hoped the move to sustainable fuels, made with carbon capture, municipal waste, or biomass, will influence fuel companies to move to mainstream production.

Formula 1 has rejected a move to electric vehicles for 2026, but the regulations feature a "shift of focus to electrical power" in the future.

Formula 1 promoters argue that 92% of vehicles will still be internal combustion engines in 2030, needing imminent change to the fuel industry to impact greenhouse gas emissions before widespread electric vehicle uptake.
