The new Formula 1 regulatory cycle, which will come into force in 2026 and define the future of the Circus until 2030, is often described as a major showdown between car manufacturers. Ferrari, Mercedes, Honda, Audi, Ford and, from 2028, Cadillac represent the backbone of a Formula 1 that aims to relaunch itself as a leading technological platform for the global automotive industry. This interpretation, while absolutely valid, tells only part of the story.
Alongside the battle between engine manufacturers and chassis designers, another equally strategic industrial competition is unfolding in parallel. It is less visible to the public eye, but potentially decisive: the confrontation between the major petrochemical groups tasked with developing and supplying the fuels of the future. Formula 1 from 2026 onwards will not only be a test bench for new hybrid power units, but also the most advanced laboratory in the world for high-performance non-fossil fuels.
In this environment, competitive advantage will no longer depend solely on engine efficiency or aerodynamic performance, but increasingly on the chemistry of combustion itself. As a result, fuel suppliers become central players in the technical project, on the same level as power unit manufacturers. The landscape of partnerships for the new regulatory cycle is already clearly defined and highlights the weight of the industrial giants involved.
Aramco will partner Aston Martin, Castrol will support Audi in its official entry into Formula 1, ExxonMobil will supply Red Bull and Racing Bulls, Petronas will serve as the reference fuel partner for Mercedes and, by extension, Williams, Alpine and McLaren. Shell, meanwhile, will continue its historic relationship with Ferrari, extending it to Haas and Cadillac as well. These are not simple commercial sponsorships, but long-term technological partnerships involving multi-year investments in research, development and on-track validation.
The real turning point is represented by the FIA regulations that mandate the exclusive use of 100% sustainable fuels from 2026. These fuels must not be derived from fossil sources. They fall under the category of Advanced Sustainable Fuels, which includes components produced from non-food biomass, organic waste, and chemical synthesis using captured CO₂. The objective is not only to reduce Formula 1’s environmental impact, but also to prove that such fuels can deliver performance comparable to, or even superior to, traditional fuels, even under extreme operating conditions such as those faced by power units producing more than 1,000 horsepower.

This requirement fundamentally shifts the centre of gravity of the competition. Formula 1 becomes an accelerated development platform for so-called drop-in fuels, which could potentially be used in road cars without the need for radical engine modifications. In other words, the championship is no longer just a technological showcase, but an industrial accelerator for solutions that could have a tangible impact on the global automotive sector’s energy transition.
This push could also help slow down the idea of full-scale electrification that would effectively erase more than a century of internal combustion engine development. Modern combustion engines are now capable of delivering extremely high standards of quality, efficiency and reliability, and sustainable fuels offer a pathway to preserve and evolve this technology rather than abandoning it entirely.
For the major petrochemical groups involved, the stakes could hardly be higher. Aramco, Shell, ExxonMobil, Petronas and Castrol do not view Formula 1 as a simple marketing tool, but as a high-pressure development environment in which technologies can be validated at a pace that would normally take many years. The complexity of these fuels, their chemical stability, their behaviour inside the combustion chamber and their interaction with lubricants all become critical factors in determining overall power unit efficiency.
In this scenario, even minor differences in fuel formulation can translate into tangible advantages in terms of thermal efficiency, reliability and energy management. This is a level of competition that does not appear in traditional timing sheets, yet it could have a profound impact on the balance of power on track, especially during the early phase of the new regulations, when technical convergence margins are still wide.
The economic implications of this transition should not be underestimated either. The development of sustainable fuels involves high costs and requires complex industrial infrastructure. Some teams have already pointed out that the price of the new fuels is higher than initially expected, adding another layer of pressure within an ecosystem that is trying to balance the cost cap with the need for innovation. From this perspective as well, the ability of major petrochemical groups to sustain long-term investments becomes a key differentiating factor.
The Formula 1 of the 2026–2030 cycle is therefore not just a battleground between historic automotive brands and new entrants. It is a broader technological and industrial war that directly involves the world’s leading petrochemical players, all of whom are being asked to redefine the very concept of high-performance fuel. The racetrack becomes the final stage of a process that begins in chemical laboratories and synthetic fuel plants, far from the spotlight.
Seen through this lens, Formula 1 once again confirms itself as one of the few environments where sport, industry and research genuinely converge. Not only to decide who will win world championships, but to determine who will lead the development of the fuels of the future. It is a less visible dimension, yet one that is strategically decisive, and it makes the new regulatory cycle one of the most significant in the recent history of Formula 1.
