The FIA disables Straight Mode for the upcoming Monaco Grand Prix, retaining Overtake Mode with stricter power limits, as safety concerns intensify on Formula 1’s tightest, least forgiving circuit.

Teams still wrestle with the 50:50 hybrid split, balancing combustion output and battery energy without excessive lift-and-coast or destabilizing super-clipping during critical race phases.

Monaco’s frequent braking assists regeneration, while short straights favor deployment. The limited run-off heightens risk, echoing street-circuit traits seen in Formula E competition around the Principality.

Straight Mode’s deactivation locks front and rear wing flap angles for qualifying and the race, removing any drag-reduction activation and demanding stability from mechanically generated grip and downforce.

To aid rare passing, the FIA retains Overtake Mode but caps electric delivery. The 350 kW ceiling declines linearly from 200 km/h, reaching zero by 300 km/h, 90 km/h earlier.

With Overtake Mode engaged, output sustains longer: 350 kW at 200 km/h reduces to 150 kW at 300 km/h, then cuts abruptly to zero at 310 km/h.

The profile tempers acceleration after the tunnel. Simulations indicated near-340 km/h with previous mappings, an unacceptable prospect given Monaco’s confines and the Nouvelle chicane approach.

Power limits reshape deployment maps, brake-by-wire targets, and energy harvesting windows. Fixed flaps narrow setup freedom, shifting emphasis to ride control, traction, and predictable balance.

Teams with efficient regeneration and stable rear platforms should benefit. Mismanaged deployment risks tyre temperature swings, traction losses, and compromised launch from slow corners.

The policy underscores how the FIA balances performance with driver safety, prioritising predictability over peak speed on circuits with minimal run-off.

Expect these constraints to inform future street-circuit tuning, amid an ongoing F1 teams debate on 2026 power profiles and deployment freedoms.

With Monaco imminent, the field will prioritise conservative ride heights, robust cooling, and disciplined energy use to deliver lap-time consistency without triggering safety margins.
