Among the clauses of the Formula 1 regulations for 2026, one carries its effect out of the circuit and into industry: the fuel is now 100% sustainable. That means a liquid fuel made from non-fossil sources — biological waste, captured carbon or renewable hydrogen — rather than from refined crude oil.
The decisive technical detail is that this fuel runs in a conventional internal combustion engine without radical redesign. That is where its commercial importance lies: if it needed a different engine it would have remained a laboratory solution, but being a direct substitute makes it applicable to an existing fleet.
What changed in the Formula 1 rules — 2025 vs 2026
| # | Item | Through 2025 | From 2026 |
|---|---|---|---|
| 1 | Electric output | ≈120 kW | ≈350 kW |
| 2 | Power split | Mostly combustion | About 50% combustion, 50% electric |
| 3 | MGU-H unit | Present | Removed |
| 4 | Fuel | Partly sustainable blend | 100% sustainable |
| 5 | Aerodynamics | Moveable rear wing (DRS) | Moveable aero front and rear |
| 6 | Overtaking aid | DRS | Extra electric power for the following car |
| 7 | Minimum weight | 800 kg | 768 kg |
| 8 | Maximum car width | 2,000 mm | 1,900 mm |
The largest regulatory shift in the sport since 2014: an electric side approaching the combustion side in output, fully sustainable fuel, and a lighter, narrower car. Qatar and Abu Dhabi are the first two Gulf rounds run under these rules. — Source ↗
That difference is what explains the interest of energy companies in the file. An electric car replaces the engine, the drivetrain and the infrastructure together; sustainable fuel replaces a single molecule in a chain that already exists in full — refineries, distribution stations and engines remain, in principle, as they are.

The Gulf dimension here is direct. The region holds the largest concentration of refining and petrochemical capacity in the world, and Saudi Aramco — global partner of Formula 1 and title partner of the Aston Martin team — works on synthetic fuel research. The sport in this case is not marketing sponsorship alone, but a public testing platform for a technology whose development concerns the parent industry.
The economics remain the fundamental obstacle. Synthetic fuel costs considerably more than fossil fuel, and Formula 1 can absorb that cost because its volume is small and its publicity value high. Converting production at market scale requires a cost reduction that has not yet been achieved, or a carbon pricing policy that changes the equation.
For the Gulf reader the practical question is not whether their car will run on sustainable fuel soon — it will not. The question is whether this path will give the region’s refineries a new market able to absorb their existing assets in a world where the share of fossil fuel in transport is falling.
Gulf Auto will follow what is announced on production capacity and cost in this field, with a clear distinction between what is actually produced and what remains in research.
