FIA retains "quite a lot of flexibility" to fine-tune 2026 Overtake Mode throughout season

Formula 1's regulatory overhaul for 2026 represents one of the most significant technical transformations in the sport's modern history, and the FIA is taking a measured, adaptive approach to one of its most consequential innovations. Nikolas Tombazis, FIA single-seater director, has confirmed that Formula 1 possesses "quite a lot of flexibility" to adjust the new Overtake Mode throughout the 2026 season, ensuring that the sport's primary passing mechanism can be fine-tuned based on real-world performance data and on-track behavior.

Understanding 2026's Overtake Mode revolution

Overtake Mode represents a fundamental departure from the Drag Reduction System that governed Formula 1 overtaking for 15 consecutive seasons beginning in 2011. Rather than a simple rear-wing adjustment restricted to designated zones, Overtake Mode delivers 0.5MJ of additional electrical energy to drivers positioned within one second of the car ahead when they pass over a detection zone—typically the final corner. This shift reflects F1's broader pivot toward hybrid power units featuring a near-50:50 split between combustion and electric power, making energy management infinitely more complex and strategically nuanced than in previous regulations.

Unlike its predecessor, Overtake Mode can be deployed strategically across an entire lap, rather than being confined to narrow activation windows. The system permits a maximum power output of 350kW up to 337km/h when activated, compared to 290km/h in standard configuration—a substantial performance differential that can be decisive in wheel-to-wheel battles.

The challenge: unknown performance envelopes

The primary reason the FIA requires this flexibility stems from unprecedented uncertainty surrounding how teams will implement the new regulations. "One thing we don't have at the moment is we haven't seen exactly the performance envelopes of all 11 cars," Tombazis explained. With 11 competing teams developing fundamentally new power units and chassis architectures simultaneously, no organization—not even the FIA—possesses precise predictive data about comparative performance levels.

This knowledge gap is not a weakness in regulatory planning; rather, it represents an honest acknowledgment that Formula 1 has entered genuinely uncharted territory. The 30kg weight reduction, 200mm shorter wheelbase, and substantial aerodynamic restructuring mean teams face a steep developmental learning curve, and early season performance will likely differ markedly from pre-season simulations.

Strategic adjustment mechanisms

Tombazis emphasized that the FIA's flexibility operates within structured parameters. Crucially, adjustments will not occur arbitrarily during race weekends—"we don't change them on Friday at the racetrack"—but rather following advance simulation and strategic planning. "These parameters, how you set up the overtake zones, etc., are parameters that you can adjust," Tombazis confirmed, with teams receiving adequate notice before modifications take effect.

The FIA can theoretically adjust Overtake Mode settings on a race-by-race basis, calibrating power deployment windows and activation thresholds to suit each circuit's unique characteristics. A power unit's performance envelope at Monaco will differ substantially from that at Silverstone or Monza, requiring differential energy management strategies. By retaining adjustment authority, the FIA can ensure that Overtake Mode remains neither excessively dominant nor functionally impotent across F1's diverse calendar.

Balancing competitive integrity and racing quality

This regulatory flexibility serves a dual purpose: protecting competitive integrity while optimizing on-track racing. If Overtake Mode proves too powerful early in the season, dominant teams could accumulate insurmountable championship leads before the midseason break. Conversely, if energy deployment proves insufficient, the 2026 season risks becoming processional, undermining F1's stated objective of closer racing and enhanced overtaking opportunities.

The 2026 regulations explicitly prioritize driver control and racecraft over mechanical aids. By retaining modification authority, the FIA safeguards this philosophical foundation while gathering empirical evidence about how Overtake Mode actually functions when experienced by 20 drivers operating sophisticated hybrid power units at the absolute limit.

As F1 enters this transformative era, the FIA's methodical, data-driven approach to Overtake Mode adjustment will prove instrumental in determining whether 2026 fulfills its regulatory promise: rewarding driver skill, facilitating overtaking, and delivering competitive, unpredictable racing across every venue on the calendar.
