Formula 1’s new generation of cars will be subject to additional speed-control measures at the Monaco Grand Prix, with the FIA introducing circuit-specific engine settings alongside the removal of the sport’s new active aerodynamic system.
The streets of Monaco have always presented a unique challenge for Formula 1 teams, but the arrival of the 2026 technical regulations has prompted governing body officials to take extra precautions at the Principality’s famously unforgiving circuit.
Earlier this week, it was confirmed that Formula 1’s new “straight mode” aerodynamic feature — designed to reduce drag on faster sections of track — will not be used in Monaco. The decision makes the Principality the first venue on the 2026 calendar where the system has been completely disabled.
However, the aerodynamic restriction is only part of a wider package of safety measures.
Teams will also be required to run a modified engine map that alters how electrical power is deployed from the cars’ new 350kW MGU-K systems. The revised configuration has been designed to reduce acceleration at higher speeds and prevent cars from reaching excessively high velocities in areas such as the start-finish straight, the tunnel and the climb towards Casino Square.
Under the standard 2026 power settings, the electric motor can deliver its maximum output up to approximately 290 km/h before power is gradually reduced. In Monaco, the FIA has introduced a more aggressive reduction strategy, with full electrical assistance available only up to around 200 km/h before output begins to taper off.
The result is that drivers will still benefit from strong acceleration out of Monaco’s many slow-speed corners, but the electric contribution will decline much earlier as speeds increase, helping to keep top speeds under tighter control on the narrow street circuit.
The move reflects concerns that the combination of powerful new hybrid systems and active aerodynamics could push corner-entry speeds beyond comfortable limits at a venue where barriers sit just metres from the racing line and run-off areas are virtually non-existent.
Despite the changes, overtaking assistance will remain available through Formula 1’s new overtake mode, although its deployment characteristics have also been adapted for Monaco. Rather than extending maximum electrical power deep into the higher speed range, the system will provide a shorter but more concentrated performance boost during acceleration phases.
The modifications are not expected to create significant energy-management challenges for teams. Monaco’s layout features numerous heavy braking zones, allowing drivers to recover large amounts of energy throughout a lap and maintain battery reserves more easily than at many other circuits.
With Formula 1 entering a new technical era in 2026, Monaco once again finds itself requiring a bespoke approach. The FIA’s latest measures underline the unique demands of the world’s most famous street race, where performance must always be balanced against safety on one of motorsport’s most challenging tracks.
