Audi slams brakes on F1’s V10 revival push

Audi has thrown a wrench into Formula 1’s flirtation with a nostalgic return to V10 engines, firmly opposing any move to ditch the turbo hybrid rules set for 2026.

As the FIA explores scrapping the incoming regulations in favor of V10s powered by sustainable fuels as early as 2028 or 2029, Audi has emerged as a staunch defender of the hybrid path, citing its critical role in the brand’s F1 entry.

The debate, simmering among manufacturers, has split opinions, with Ferrari and Mercedes publicly open to considering a change of format while Audi digs in its heels.

In a statement provided to the media, Audi underscored the 2026 turbo hybrid rules—featuring a 50/50 power split between combustion and electric energy—as pivotal to its F1 commitment.

“The upcoming regulation changes, including the new hybrid power unit regulations set for the 2026 season and beyond, were a key factor in Audi's decision to enter Formula 1,” the company declared.

“These power unit regulations reflect the same technological advancements that drive innovation in Audi's road cars.”

For Audi, the hybrid tech isn’t just racing spec—it’s a bridge to its road-going future.

A Clash of Visions

The FIA’s push to rethink the turbo hybrids is rooted in cost concerns, with the current engines deemed too pricey. The governing body has floated the idea of a shift to V10s by 2028, a move requiring backing from the FIA, Formula One Management, and four of the sport’s five manufacturers.

While Audi’s opposition alone can’t derail the plan if Mercedes and Honda align with Ferrari and Red Bull, the FIA’s single-seater director Nikolas Tombazis insists fairness trumps the majority rule.

“Above all, the obligation is to be fair, and people have invested a lot of money,” Tombazis said.

“If nine people are in favour and one person is against and that one person is being treated unfairly, we will always also try to protect the one person. We won't just go on majorities and say 'OK let's do it'.”

Red Bull’s Christian Horner, a V10 advocate, acknowledged the “romantic" allure but questioned the timing.

“The romantic in you - a screaming V10 - so long as it’s done responsibly, with fully sustainable fuels, is hugely attractive,” he said in China.

“I think the big question is: when would that be for? And what would be the game plan between where we sit today and then?

“Because it would be a massive departure obviously to move away from what is currently being worked on very hard for 2026.”

Logistical Nightmares and Commitments

Scrapping the 2026 rules outright would need unanimous consent – a tall order given Audi and Red Bull/Ford lack current-spec engines, and Honda’s team switch from Red Bull to Aston Martin complicates matters further.

The 2026 hybrids, designed to lure new players like Audi and reverse Honda’s exit plans, have already shaped manufacturer strategies. Audi’s investment in this tech isn’t easily undone, and any delay risks leaving newcomers stranded.

Mercedes boss Toto Wolff, meanwhile, straddles the fence.

“We as Mercedes are always open, whether that’s in the future an eight or ten cylinder, naturally aspirated or turbo, energy recovery and whatever size,” he said.

“I think we’re racing with exciting regulations next year that were brought in by the FIA to accommodate newcomers like Audi, and I guess we achieved that.”

His openness contrasts with Audi’s resolve, leaving Honda’s stance as a wildcard.

Consensus or Stalemate?

The FIA’s Tombazis emphasized consensus over coercion.

“We're trying to build consensus here, and if that fails, then we will stay where we are,” he said.

For Audi, staying put means sticking with a turbo hybrid future that aligns with its brand ethos, even as V10 nostalgia tempts others.

Horner lamented the current rules’ flaws – “We’ve ended up in a situation where the chassis is having to compensate a huge amount for perhaps some of the shortcomings of the split in electrification and combustion” – but Audi sees them as a foundation, not a burden.

With the clock ticking toward 2026, Audi’s public stand signals a broader battle over F1’s technical soul. Will the sport embrace a sustainable hybrid evolution or chase the piercing, high-pitch scream roar of a V10 past?

For now, Audi’s betting on the former – and it’s not budging.
