Formula 1 could be heading for a major change in the future, as the idea of bringing back V10 engines is being seriously considered for the first time in years. These powerful, loud engines were last used in 2005 and are still loved by many fans.

But this time, the comeback wouldn’t mean going backwards as the plan would be to power the V10s with sustainable fuel, making them much cleaner and more modern than before.

This discussion has picked up speed after FIA president Mohammed Ben Sulayem recently said that it’s time to explore the possibility. The FIA’s single-seater director, Nikolas Tombazis, later confirmed that the idea is on the table. There’s no official plan yet, but he didn’t rule it out, and even hinted that it might happen before the current engine cycle ends in 2031.

Right now, Formula 1 is preparing for new engine rules in 2026, with more focus on electric power and hybrid systems. Manufacturers like Audi and Honda made their decisions to join or return to the sport based on these rules, which makes things more complicated. Audi has already said it’s committed to the hybrid path, and Honda hasn’t yet commented on a possible change to V10s.

Still, according to Motorsport.com, the FIA has arranged a meeting with all F1 engine manufacturers during the Bahrain Grand Prix to talk things through. The exact details of the meeting aren’t public, but it’s expected to explore whether there’s enough support for a V10 return.

One idea being talked about is extending the current engine regulations by two years, then switching to V10s in 2028. At first this seemed unlikely, but more people in the paddock now believe it could be a realistic plan.

This shift in thinking also matches what’s happening in the wider car industry. Instead of pushing further into electric-only technology, there’s growing interest in sustainable fuels. A V10 engine that runs on clean fuel would be cheaper and simpler than the complex hybrid systems, and with fans already excited about the idea, the return of the V10 might not be so far-fetched after all.
