The world's most expensive petrol is not sold at an isolated petrol station, nor in a country with high fuel taxes. It is used on Formula 1 tracks and from the 2026 season will cost around 250 euros per litre, almost ten times the cost of the fuel used by single-seater cars in previous years.
This price is not due to an oil shortage or a geopolitical crisis. It is the result of the technology that is inside every gas station. With the implementation of the FIA's new technical regulations, Formula 1 has switched to a fossil-free fuel, which must have a neutral carbon footprint throughout its entire life cycle.
The new fuel is one of the most ambitious technological ventures in the history of motorsport and a key part of Formula 1's efforts to achieve zero carbon emissions by 2030.
Why does it cost 250 euros per liter?
Formula 1 fuel is not produced through conventional refining processes. Its composition is based either on synthetic fuels, known as e-fuels, or on advanced biofuels.
Synthetic fuels are created using “green” hydrogen and carbon dioxide captured from the atmosphere. The process requires large amounts of clean electricity and highly complex technological infrastructure.
On the other hand, advanced biofuels are produced from inedible biomass, agricultural residues and organic waste. And in this case, processing is difficult and expensive, as the final product must meet the extreme requirements of a single-seat aircraft.
Some of the world's largest energy groups, such as Shell, Aramco, Petronas, ExxonMobil and BP/Castrol, are involved in the development of these fuels. Each company is following a different technological path, seeking to create a fuel that is efficient, sustainable and fully compatible with new engines.
Small production, high costs
The price of 250 euros per liter is not an indication of the cost of a similar fuel if it were mass-produced.
In Formula 1, quantities are extremely limited, while the specifications are much stricter than those of a commercial fuel. Each batch undergoes continuous laboratory testing to ensure exactly the same performance at different temperatures and operating conditions.
Engineers examine the fuel's energy density, stability, combustion behavior, and how it interacts with the hybrid system. Even a small change in chemical composition can affect engine performance and save precious milliseconds per lap.
So the price doesn't just reflect the cost of raw materials. It includes research, testing, failed formulations, and developing a product that is at the limits of available technology.
Fuel, as part of racing performance
In the past, fuel was seen primarily as a consumable. Today, it is one of the most important elements of a car's overall performance.
The new 2026 engines combine the combustion engine with significantly greater electric power. The relationship between the two systems is closer, meaning that fuel quality directly affects power management, acceleration and economy.
Modern V6 Turbo Hybrid engines have a thermal efficiency of close to or even above 50%. This means that they convert more than half of the fuel's energy into motion, while a conventional road engine loses much more as heat.
High efficiency limits the amount of fuel required during a race. At the same time, the FIA ??now controls not only the volume of fuel but also the energy that can be used, so that no team gains an advantage through chemistry alone.
From the track to production machines
Despite its high cost, the new fuel is not designed exclusively for racing use.
The FIA ??claims that it can be used in conventional internal combustion engines without significant modifications. This is a crucial advantage, as hundreds of millions of vehicles with petrol and diesel engines will continue to be on the road for many decades.
Fully electric propulsion cannot be implemented at the same speed in all countries and in all sectors. For this reason, sustainable fuels can act as a complement, reducing emissions from the existing vehicle fleet.
The technology could also find applications in trucks, ships and aircraft, where the use of batteries remains more difficult due to weight, range and the need for rapid fuel supply.
Reactions to cost
The transition has not been without problems. Senior team leaders have expressed concerns about the speed at which development costs have increased.
Mercedes' Toto Wolff has said the costs involved have significantly exceeded initial estimates. This has led to discussions about possible restrictions to avoid unrestricted competition between suppliers and teams.
The difficult part is containing costs without halting technological development. Formula 1 wants to remain a laboratory for innovation, but at the same time seeks to keep team budgets sustainable.
An expensive bet with broader value
Petrol at 250 euros per litre is now an extremely expensive and specialised product. However, many technologies that started in Formula 1 later migrated to everyday driving. Hybrid systems, energy recovery, advanced lubricants and more efficient engines were first developed in racing conditions. The same could happen with sustainable fuels.
The most expensive gasoline on the planet is found, therefore, in Formula 1 cars. Its real value, however, is not measured solely by the price per liter. It is mainly measured by whether its technology can be made cheaper, produced on a large scale and contribute to reducing emissions throughout the global economy.
