F1 at a Crossroads: Two Parallel Engine Debates Shape the Sport’s Future
Formula 1 is currently navigating two distinct but interconnected discussions about its engine regulations, each carrying significant implications for the championship’s trajectory. The more urgent conversation focuses on addressing immediate performance issues with the new power units introduced this season, while a longer-term debate examines the fundamental engine architecture for the next regulatory cycle.
According to sources, a resolution on the short-term fixes is needed within weeks if changes are to be implemented for the 2027 season. These talks are already well advanced. The second, more strategic discussion concerns the engine formula that will take effect when regulations change again in 2030 or 2031.
The Short-Term Fix: Addressing Energy Management Issues
The most pressing concern among drivers centres on how the current engine regulations have affected qualifying sessions. The requirement for extensive energy management has prevented drivers from pushing to the absolute limit in traditional qualifying trim, with several fast corners being reduced to what Aston Martin’s Fernando Alonso has described as “charging stations.”
Some progress was made at the Miami Grand Prix, where a series of engine modifications allowed faster energy recovery and reduced the total amount of deployable energy. However, all stakeholders agree that further adjustments are necessary.
Following Miami, engine manufacturers have agreed to explore ways to increase the proportion of power generated by the internal combustion engine for 2027. A conclusion is expected within the next two weeks.
The simplest solution—increasing the fuel-flow limit—would require design changes to the engines and larger fuel tanks. This creates complications, as some teams wish to carry over their chassis into 2027 for cost reasons. Potential workarounds include a cost-cap allowance for chassis modifications, slightly shorter races, or leaving race energy management as is while fixing qualifying specifically.
Other options under consideration include increasing the harvesting limit for faster energy recovery, reducing maximum electrical deployment, or enlarging the battery to store more energy.
The Long-Term Vision: A Return to V8 Power?
FIA President Mohammed Ben Sulayem is championing a more dramatic shift for the next engine cycle: a return to naturally aspirated V8 engines with a minimal hybrid component—essentially the formula F1 last used in 2013.
Ben Sulayem told US magazine Car and Driver that he wants V8s “for the sake of sustainability when it comes to the business, the price, the efficiency, the light weight, the sound for the fans; I think you are ticking many boxes here.”
The current Concorde Agreement—which binds teams, F1’s commercial rights holder, and the FIA—runs until the end of 2030. In theory, Ben Sulayem could impose new engine rules unilaterally for 2031 when the current governance processes expire. He is using this leverage to push for implementation as early as 2030.
“It is happening,” Ben Sulayem said, “but of course consultation is needed.”
However, unilateral action carries significant risk. The current engine regulations attracted three new manufacturers—Audi, Ford, and General Motors—and persuaded Honda to reverse its decision to leave the sport. Any move that alienates these stakeholders could trigger departures.
Weight Considerations: Lighter Cars on the Horizon?
The weight argument aligns with a broader consensus that modern F1 cars are too heavy, even after a 30kg reduction this season. Current power units weigh 185kg, including the engine, turbo, electrical components, and battery. By contrast, the 2.4-litre V8s used in 2013 weighed 130kg, with the internal combustion engine itself accounting for just 95kg.
However, fuel loads complicate the comparison. In 2026, F1 cars start a grand prix with 90kg of fuel, compared to 160kg in 2013. Without hybrid systems, an engine would be lighter but would require significantly more fuel. A 2013 car had a total engine and fuel race-start weight approximately 15kg heavier than current cars, though this would be about 55kg less at race end and during qualifying.
Modern safety systems, including the halo head-protection structure, prevent direct total car weight comparisons. Insiders suggest that smaller, simpler engines could also enable slightly narrower and lighter chassis.
The Noise Debate: Louder Engines, Louder Concerns
Ben Sulayem argues that a return to the dramatic noise of V8s—and V10s before them—would be popular with fans. However, the noise argument has two distinct sides.
A portion of the audience undoubtedly prefers the louder, more strident sound of naturally aspirated engines used from 1989 until 2013. Yet there is no conclusive data or research quantifying this preference—only anecdotal evidence.
The counterargument is equally compelling. A whole generation of fans has joined F1 since turbo hybrids were introduced in 2014. The sport has experienced significant growth since Liberty Media acquired commercial rights in 2017, expanding social media presence and introducing the Netflix series Drive to Survive.
Quieter engines have become the norm for these newer fans, who have no experience of races where conversation is impossible without ear protection. Significantly louder engines could threaten city-centre races in Miami, Las Vegas, Singapore, and even Monaco—some of the most commercially important events on the calendar.
Ben Sulayem has acknowledged this concern, suggesting engine speeds should not exceed 15,500-16,000rpm to avoid being “annoying to young kids.” There has even been discussion about using mufflers, despite the apparent logical inconsistency.
Stakeholder Positions: Diverging Views on the Path Forward
Manufacturers appear broadly open to changing the engine formula, including switching to a V8—a marked contrast to Ben Sulayem’s previous attempt to introduce a naturally aspirated V10, which was outflanked by manufacturers just over a year ago.
There is general agreement on the need to reduce costs following the expensive development of current engines. However, there is no consensus on the exact architecture.
Mercedes F1 boss Toto Wolff said his team is “open” to discussions, adding that they “loved V8s.” However, Wolff cautioned: “How do we give it enough energy from the battery side to not lose connection to the real world? Because if we swing 100% combustion, we might be looking a bit ridiculous in 2031 or 2030. So we need to consider that, make it simpler and make it a better engine.”
Honda told BBC Sport that a return to V8s “is something we should discuss healthily, the FIA and the stakeholders, while ensuring that it is for the benefit of the fans.”
In his Car and Driver interview, Ben Sulayem mentioned an engine capacity between 2.6 and three litres, with 10% of total power from electrical elements. Some insiders suggest he would prefer 5% or even zero electrification but recognises that would not be viable.
F1 boss Stefano Domenicali is also open to a V8, though he has spoken enthusiastically about the “yo-yo racing” created by current engines—a direct result of increased electrification. Removing that electrical component would eliminate the levers F1 uses to maintain this racing style.
Mercedes driver George Russell has pointed out that while F1 20 years ago “arguably was the purest Formula 1 we’ve ever seen, the racing was dull.”
Some insiders suggest a compromise figure of around 30% electrical power might be more realistic. The question of turbocharging also divides opinion, with Audi reportedly favouring its retention. Honda stated that “regardless of the turbo or hybrid application or the format of the power-unit, we highly regard F1 as essential technological challenges.”
A turbo engine is more road-relevant and efficient than a naturally aspirated one, requiring less fuel—though turbos and their associated architecture add weight and complexity, while producing less noise.
Initial discussions are underway, but substantive conversations can only begin once the FIA presents a formal proposal. Given that current engine rules were initiated in 2020-21 for a 2026 introduction, time is pressing for decisions on the next regulatory cycle.
