FIA rules out ICE-electric power split changes for 2026 Formula 1 season. The FIA confirms that the 50/50 internal combustion and electric power split will remain unchanged for 2026 F1 engine regulations.

The FIA has clarified that the 2026 Formula 1 engine regulations will not include any adjustments to the controversial power split between the internal combustion engine and electric components, despite ongoing criticism from teams and drivers. This announcement comes as discussions over the so-called “superclipping” issue continue to generate debate across the paddock.

April set to be pivotal for FIA engine discussions

Throughout April, Formula 1 teams and technical staff are closely monitoring potential regulatory updates as the FIA evaluates how best to address power unit performance under the current framework. The focus has centered on the balance between the internal combustion engine (ICE) and the energy recovery systems, a topic that has sparked extensive discussion among engineers and drivers, including those at Ferrari and Mercedes.

FIA delivers early guidance on engine regulations

In the weeks leading up to the Miami Grand Prix, FIA meetings highlighted the possibility of revisiting the power split to mitigate superclipping concerns. One idea that has been floated internally involves shifting the existing 50/50 distribution between ICE and electric motor power to an alternative ratio, like 60/40. However, according to technical sources cited by Thomas Maher on PlanetF1, the likelihood of implementing such a change for 2026 is effectively zero. Modifying the power split would require extensive re-engineering of the current power units, which have been developed over multiple seasons, making short-term alterations impractical.

Looking ahead to 2027 for potential power unit changes

While the debate over the optimal power distribution continues, the FIA appears to be deferring any substantial modifications to the 2027 regulations. This approach gives teams and drivers—including Ferrari’s Charles Leclerc and Lewis Hamilton—the necessary time to evaluate performance implications, simulate alternative configurations, and prepare their power units for future seasons without disrupting the current 2026 campaign.

In summary, Formula 1 fans can expect the 50/50 ICE-to-electric power split to remain in place for 2026, with engineers and teams focusing on optimizing performance within the existing framework while keeping a close eye on potential adjustments in 2027.
