Christian Horner, Red Bull Racing’s Team Principal, supports a return to V10 engines in Formula 1, following comments from FIA president Mohammed Ben Sulayem advocating sustainable fuels in future regulations. While the 2026 rules will see a hybrid engine, both figures highlight the allure of V10s with sustainable options. The timeline for any engine switch could begin by 2030.
Christian Horner, Team Principal of Red Bull Racing, has expressed support for a possible return to V10 engines in Formula 1. Following comments from FIA president Mohammed Ben Sulayem, who suggested a shift back to conventional engines using sustainable fuels, Horner indicated that he favours this direction for future F1 engine regulation.
In the upcoming 2026 regulations, F1 will implement a 50/50 split between a V6 internal combustion engine and an electric MGU-K motor, utilising fully-synthetic fuel. However, Horner advocates for the reintroduction of V10 engines powered by sustainable fuel, citing their appeal and the potential for reduced cost and complexity.
Reflecting on the future of F1 engines, Horner stated, “I think the purest in me would love to go back to a V10 that was done responsibly, with sustainable fuel.” He believes that the engaging sound of V10s could enhance the experience of grand prix racing.
Ben Sulayem’s recent social media post emphasised the importance of considering various engine formats, including naturally-aspirated engines, and the iconic V10 sounds. With the introduction of new regulations in 2026, there is enthusiasm surrounding potential changes by 2030, encompassing both technological innovation and cost control for teams.
Christian Horner supports the idea of returning to V10 engines in F1, aligning with FIA president Ben Sulayem’s vision for sustainable fuels. While 2026 regulations will introduce V6 hybrids, both leaders see value in reviving V10s for their performance and iconic sound. The earliest potential revival could be seen by 2030, keeping team costs manageable during the transition.
