Christian Horner supports V10 engine return in Formula 1. Emphasising the need to bring back the “sound of Grand Prix racing.”
Red Bull team principal Christian Horner has expressed his enthusiasm for the potential return of V10 engines to Formula 1. He claims the sport should return to its roots despite introducing a new generation of power units in 2026. New engine regulations feature a V6 internal combustion engine with increased electrification, and discussions around the future of F1’s engine formula continue.
The Debate Around V10 Engines
This conversation began following comments from FIA president Mohammed Ben Sulayem, who expressed an interest in returning V10 engines to the sport.
Sulayem was interested in reviving the high-revving, naturally aspirated engines of the past. The catch is that sustainable fuels would be used to abide by the FIA’s net zero by 2030 plan. The FIA confirmed that a working group will be formed to explore the feasibility of such a change beyond the 2026 regulations.
In a statement to PlanetF1.com, the FIA said
“We are engaged in discussions with several stakeholders to determine the future technical direction of F1 beyond the 2026 regulatory cycle. A V10 power train running on sustainable fuel would be part of those considerations, which would be tied to environmental and cost-containment measures.”
Christian Horner acknowledged the complexities and high costs which are associated with the 2026 power units. Noting that whilst they are technologically advanced, they are extremely expensive and intricate for teams and drivers to navigate.
“Personally, from a sporting perspective, looking at what the future engine in Formula 1 should be beyond this next generation. I think, particularly with the way that sustainable fuel is going in, [it] does open up all kinds of opportunities,” Horner explained.

“I think the purist in me would love to go back to a V10 that was done responsibly with sustainable fuel, that reintroduced the sound of Grand Prix racing. It’s an interesting concept. One to certainly look for, for after this current set of regs.”
A return to V10 engines would undoubtedly bring back memories for many fans. Especially those who deem it to be the golden era of Formula 1.
However, these engines must align with modern sustainability goals, ultimately posing a difficult quest for the governing body. If the FIA’s working group finds a way to make such an engine possible, this vision could be a reality.
The sport will enter a new era in 2026, with extensive new technical regulations set to shake up the sport. Despite this significant step forward, the FIA struggles to balance innovation and maintain the sports heritage. However, the long-awaited return of a sustainable V10 engine could be the solution.
