FIA Suggests Potential Comeback of V10 Engines in Formula One with Sustainable Fuel Innovation Untapped

LONDON, Feb 22 — Formula One could be heading toward a much louder future as the FIA sparks discussions about bringing back roaring V10 engines—this time powered by fully sustainable fuel.

Since 2014, F1 cars have been equipped with 1.6-liter V6 turbo hybrid engines, with new regulations set to take effect from 2026 to 2030. While technologically advanced, these engines are expensive and significantly quieter than the high-revving, naturally aspirated V10s that thrilled fans until their final appearance in 2006.

FIA President Mohammed Ben Sulayem fueled speculation in an Instagram post reflecting on Formula One’s loud and electrifying 10-team launch event in London last Tuesday. During the event, the FIA was met with boos from the 15,000-strong crowd.

“This week’s F1 launch in London has sparked positive discussions on the sport’s future,” Ben Sulayem wrote on Thursday. “While we anticipate the introduction of the 2026 chassis and power unit regulations, we must also lead the way in motorsport’s technological evolution.”

He suggested exploring different directions, including the return of V10 engines using sustainable fuel. “Whichever path we take, we must support teams and manufacturers in managing R&D costs,” he added.

An FIA spokesperson confirmed that discussions are underway regarding F1’s technical direction beyond 2030, with a working group likely to be established to evaluate various options.

“A V10 powertrain running on sustainable fuel is one possibility under consideration, aligned with environmental and cost-control measures,” the spokesperson said. “While our focus remains on implementing the 2026 regulations, we must also look ahead.”

Some manufacturers may welcome a shift toward simpler, more affordable engines, despite V10s being a step back in technology. Brands like Renault-owned Alpine, which is moving toward an all-electric future, recognize F1 as a key marketing platform and value the sport’s entertainment factor.

F1 CEO Stefano Domenicali previously hinted at the idea, stating, “If sustainable fuel achieves zero emissions, we may no longer need such complex and expensive engines. We could consider returning to lighter engines with a more exciting sound.”
