FIA reveals failed push to fix 2026 power unit rules

FIA technical chief Nikolas Tombazis has admitted the governing body attempted to adjust the 2026 power unit regulations before they debuted but failed to secure sufficient manufacturer support under the sport's current governance model. The revelation confirms that Formula 1's current energy management struggles were anticipated years ago yet effectively locked in by a rule-making process that gives individual manufacturers outsized influence over technical direction.

Why it matters:

Drivers have heavily criticized the 2026 rules for prioritizing software and energy management over raw racing instincts, and Tombazis said the backlash did not surprise the FIA since it had identified the same concerns during development. However, attempts to fix the rules before the season began were handcuffed by a governance structure requiring approval from at least four of five power unit manufacturers, exposing a fundamental tension between sporting ideals and commercial commitments that ultimately forced mid-season fixes and a multi-year correction plan.

The details:

• Tombazis explained that simulations as early as 2022 revealed the consequences of the almost equal split between combustion and electrical power, but the development cycle was too advanced to change course.
• The 2026 PU agreement unified financial and technical rules for all manufacturers, yet also required Formula One Management and at least four PU makers to approve any regulation changes.
• When four manufacturers refused to agree on pre-season adjustments, the FIA was powerless to act until introducing changes from the Miami Grand Prix.
• Further revisions have been agreed for 2027 and 2028, gradually shifting the energy balance toward a 60-40 split favoring combustion power.

What's next:

Formula 1 returns from its summer break at the Dutch Grand Prix on August 21-23, with teams still working to master the current regulations. While Tombazis argues the racing has remained exciting despite Mercedes' dominance, the delayed fixes highlight the ongoing challenge of balancing manufacturer priorities with pure competition.
