The FIA has stated that it is seriously considering various future engine possibilities for Formula 1, which includes potentially reverting to V10 engines powered entirely by sustainable fuel.
As per FIA single-seater director Nikolas Tombazis, talks are still in their initial phase, yet all possibilities are being considered – this includes potentially reducing the duration of the 2026 power unit regulations.
At a media roundtable joined by representatives from China, Tombazis addressed the two main issues confronting the organizing body: determining the future path of the series concerning engine rules over the long term, and assessing how these changes might affect the approaching 2026 season if such modifications were implemented.
“I believe the proper approach is to consider this: Do we want to switch to a different kind of power unit three or four years from now? That’s the first question. This will ensure the sustainability of the sport in the long run,” Tombazis stated.
If the response to that is affirmative, then comes question number two – how we proceed during the interim phase. This undoubtedly takes a back seat compared to the main issue.
Tombazis emphasized that the FIA remains calm regarding the 2026 regulations, which have been ratified and are currently under development by manufacturers like Audi. Nonetheless, recent remarks from FIA President Mohammed Ben Sulayem suggesting a potential shift back to V10 engines has sparked renewed discussions about the future of power unit technology.

“Certainly, advancements in sustainable fuels have prompted opinions that perhaps engine designs could become less complex. Given the state of the global economy, there’s also an inclination towards reducing expenses further, and the present power units are excessively costly. This is indeed true,” Tombazis stated.
That’s why the president mentioned the V10 engine in ’28 and so forth. This is one aspect we are currently assessing with our power unit suppliers.
Even though the 2026 power unit rules are still current, Tombazis emphasized that the FIA is actively conversing with manufacturers and interested parties regarding the future direction.
There isn’t anything specific being proposed at this time regarding that aspect. It’s still under discussion,” he clarified further. “Regardless of whether we keep the present rules or move forward with the recently approved new ones, I believe Formula 1 will remain in a strong position.
These observations stand out, especially considering how advanced various manufacturers are with their development of 2026 engines. Several teams had earlier suggested that “the train has left the station” regarding significant alterations.
Of course, the train has largely departed from the station,” Tombazis conceded. “What I’m saying is that the FIA president raised the first query. The second inquiry follows suit and comes up frequently among many individuals, based on their position within the conversation.
We aim to be fair without showing any disrespect to any participant. Clearly, since individuals are putting in money and such, this becomes a crucial aspect of the ultimate decision.

Tombazis also tackled worries that a major shift in approach might push away new or returning manufacturers such as Audi and Honda. He stated that the FIA continues to be dedicated to achieving an equitable solution that safeguards both the championship’s long-term prospects and present commitments.
We are extremely pleased to have introduced Audi into the competition, and we completely understand their commitment. We do not wish for them to change this choice,” he stated. “Additionally, we take great pride in having encouraged Honda to reassess their exit from the sport, as they initially planned to leave but ultimately chose to return.
What we undertake involves a intricate equilibrium among these elements. You’re posing pertinent queries. Every question you raise is entirely reasonable and justified. The challenge lies in the fact that there’s not one specific answer that addresses all concerns equally—balancing fairness, safeguarding the sport, reducing expenses, defending power unit suppliers, and securing their investments. Our aim is to discover that perfect harmony.
Any significant alteration would necessitate broader endorsement from both the power unit suppliers and the teams. Tombazsi emphasized that the FIA cannot enforce a one-sided choice and would move forward solely with agreement among all parties involved.
He stated, “Whenever we make alterations, regardless of the kind of rules involved, must achieve widespread agreement. There’s a governing procedure in place. We refrain from making unilateral modifications and imposing our stance.”
The procedure encompasses two distinctive stages: obtaining endorsement from power unit manufacturers within the framework of the PU governance system, followed by independent approval from the teams should the regulations concerning the chassis also undergo changes.
The championship-winning power units from Formula One include the Mercedes-AMG F1 M09 EQ Power+ for 2018, the Mercedes-AMG F1 M08 EQ Power+ for 2017, the Mercedes-Benz PU106C Hybrid for 2016, the Mercedes-Benz PU106B Hybrid for 2015, and the Mercedes-Benz PU106A Hybrid for 2014.

“If there were ever any modifications to the chassis, these would also need approval via the governing procedures, which include accords with teams such as the Concorde Agreement and regulations like the International Sporting Code,” Tombazis further explained.
When asked about the requirement for unanimity regarding significant alterations, Tombazis declined to elaborate further.
At present, the talks continue as various parties acknowledge the sensitive equilibrium among innovation, budget management, and upholding current obligations. The direction of F1’s power unit concept – whether it leans towards hybrids, V10s, or something else entirely – stays under discussion.
