As Formula 1 prepares for a new era of hybrid power units from 2026, speculation is already swirling about a possible return to high-revving V10 engines – a move that would mark a dramatic reversal in F1’s technological trajectory. These rumours, which gained traction in the paddock during the early rounds of the 2025 season, have prompted one of the sport’s newest entrants, Audi, to issue a formal response.
As the German car giant prepares to make its debut as a full works team next year, Audi has made it clear that the hybrid regulations were a key reason for its investment in F1 – and that any sudden move away from them could send ripples through its long-term plans.
The hybrid vision that brought Audi to F1
When Formula One announced its revised 2022 power unit regulations, which will come into force in 2026, the aim was to make the sport more attractive to original equipment manufacturers (OEMs) by shifting towards sustainability, efficiency and road relevance.
The new rules doubled down on hybrid technology, with a significant increase in electric power and an exclusive commitment to fully sustainable fuels. For Audi, this was the sweet spot – a convergence of motorsport and the company’s broader push towards electrification across its road car line-up.
In a statement shared with GPBlog, an Audi spokesperson reiterated this commitment, stating, “The upcoming rule changes, including the new hybrid engine rules for the 2026 season, were a key factor in Audi’s decision to enter Formula One. These power unit regulations reflect the same technological advances that drive innovation in Audi’s road cars.
This alignment of racing and road-going technology provided Audi with the perfect platform to showcase its engineering prowess on a global stage. More importantly, it justified the significant investment required to establish a factory team in Formula One, with the company acquiring Sauber and transforming it into the official Audi F1 Team from 2026.
OEM momentum: A fragile equation
Audi isn’t alone in taking the plunge under the promise of the new hybrid regulations. Honda, which was originally set to leave F1 at the end of 2021, has since reversed its decision and will return in an official capacity in 2026 as the exclusive power unit supplier to Aston Martin.
Although it never left the paddock completely, continuing to support Red Bull and the newly rebranded Racing Bulls (formerly AlphaTauri), Honda’s formal re-commitment reflects the attractiveness of the 2026 rules.
Ford has also seized the opportunity, partnering with Red Bull Powertrains to help develop the next generation of Red Bull Racing powertrains. Meanwhile, Cadillac – part of General Motors – will enter the sport with Andretti Global, initially using Ferrari engines until its own power units are ready by 2028.
In theory, the 2026 rules have done what they were designed to do: encourage the major car manufacturers to get involved in F1. But now, with murmurs of a return to the more visceral, naturally aspirated V10s of yesteryear, the stability of that foundation could be in jeopardy.
Whispers of a V10 comeback: Romance or reality?
During the early rounds of the 2025 season, rumours began to circulate that the FIA might accelerate a return to V10 engines as early as 2028. This would be a sharp detour from the hybrid strategy agreed by all stakeholders – and a potentially disruptive one at that.
The appeal of the V10 is undeniable. Their banshee-like scream, lightweight construction and simplicity compared to today’s complex hybrid units make them a favourite with fans and drivers alike.
At a time when F1 is constantly wrestling with the balance between spectacle and sustainability, the V10 represents a romantic past. But any return to this formula would risk undermining the credibility of F1’s green transition, not to mention the planning and investment of the new OEMs.
Audi chose its words carefully in its response. While it reaffirmed its commitment to the 2026 rules, it stopped short of issuing a warning or suggesting that a change in the regulations would cause it to rethink its commitment.
As reported by GPBlog, there is currently no indication that Audi would face any penalty or recourse should the technical framework change before 2031, the date until which the new regulations are expected to apply.
Behind the scenes: Audi’s power play and governance structure
Despite the noise surrounding potential rule changes, Audi is moving full steam ahead with its F1 entry preparations. The company has assembled a leadership team with pedigree and experience.
Former Red Bull sporting director Jonathan Wheatley has been appointed team principal, bringing with him a wealth of championship-winning insight and organisational know-how. Meanwhile, former Ferrari team principal Mattia Binotto joins as Chief Operating Officer – a move that suggests Audi is serious about building a competitive operation from day one.
The transition of Sauber into a true works team is already underway. Audi’s investment in the Hinwil-based team includes the development of its own power unit in Germany, ensuring that the team will be both a chassis and engine builder – a rare and advantageous position in modern Formula One.
The team will make its debut under the Audi name in 2026, likely featuring a rebranded identity and new driver line-up to match its ambitions.
The stakes of a sudden change
While Audi has made no threats or ultimatums, the situation presents an uncomfortable juxtaposition: a manufacturer entering the sport on the promise of sustainability may find itself confronted by a sport contemplating the opposite direction.
For a brand like Audi, whose reputation is built on cutting-edge technology and environmental responsibility, the idea of returning to V10s – no matter how exciting – may not be in line with its corporate strategy.
More broadly, the V10 rumours raise questions about F1’s strategic coherence. The sport has gone to great lengths in recent years to promote its green credentials, launching initiatives such as ‘Net Zero by 2030’ and switching to biofuels.
A return to fuel-hungry V10s would almost certainly require a recalibration of that message – not to mention the support of stakeholders such as Liberty Media, the FIA and the manufacturers currently investing in hybrid technology.
2026 vs. 2028: a crucial two-year window
If the rumours of an accelerated rule change by 2028 are true, Formula One faces a delicate situation. It risks alienating OEMs that have made commitments based on the 2026 framework – not just Audi, but also Honda, Ford and Cadillac.
These companies have already started allocating resources, hiring staff and making long-term technical decisions based on the agreed hybrid formula.
For Audi, the years between 2026 and 2028 will be crucial. The team will build its identity, refine its technology and work towards competitiveness. A mid-cycle switch to a completely different powertrain concept could disrupt these efforts, not to mention undo years of planning and development. There’s no official timetable for such a change, but the mere suggestion is enough to make stakeholders nervous.
The bottom line: F1’s future hangs in the balance
F1 has always walked a tightrope between innovation and entertainment, and the latest rumours of a V10 revival add another layer to that balancing act. For Audi, the message is clear: the hybrid era was the reason for its arrival.
If the sport abandons that path too quickly, it risks more than just regulatory confusion – it could lose the trust of the very manufacturers it has worked so hard to attract.
As things stand, no formal decisions have been made and the 2026 regulations remain in place. But with Audi now publicly stating the importance of these rules to its participation, the ball is in F1’s court. Will the sport stay the course and continue its evolution towards sustainability, or will the call of nostalgia prove too tempting to resist?
The next few seasons could define not only the technological future of Formula One, but also its identity in the eyes of manufacturers, fans and the wider world. And Audi is watching closely.

I don’t know about the UK, but here, in Australia, car dealers complain that they have acres of unsold EV’s, with Hybrids outselling them.
Let’s go screaming V10 !!!!
Carbon neutrality doesn’t depend on cylinder number or fuel quantity when it comes to synthetic fuels, so the “green” argument is null
Secondly, while I get OEM’s wanting consistency, Audi of all OEM’s being publicly disgruntled by the potential rule change is strange, considering their R8 had one of the most prolific V10s of recent years. Ford had the triton, honda made V10’s for previous years, and cadillac had… concept cars, but the other three could be seen as somewhat hypocritical denying a return that would no doubt boost viewership.
