F1 to run without active aero straight mode in Monaco

Formula 1’s new active aerodynamics system will not be used in straight mode during the Monaco Grand Prix weekend, as the FIA has chosen not to designate any activation zones around the street circuit.

Under the 2026 regulations, cars feature movable front and rear wings that reduce drag on straights before returning to a high-downforce configuration in corners.

While Monaco previously featured a DRS zone on the start-finish straight, the FIA concluded that the track does not offer a suitable section for the new straight mode system.

One of the key factors is that the FIA only wants the system to operate in areas where drivers are not at the limit of tyre grip. This includes not only cornering loads, but also heavy braking and traction zones, where switching aero configurations could affect car stability.

With Monaco heavily reliant on traction and braking throughout the lap, the circuit was considered unsuitable for straight mode activation.

Another important element is the FIA’s “three-second rule”, which requires each activation zone to last longer than three seconds. The aim is to avoid very short deployments that would increase driver workload without delivering meaningful gains in performance or fuel efficiency.

Safety considerations also played a major role in the decision. The FIA evaluated whether the system could be used safely not only during low-fuel qualifying laps, but also late in race stints when tyre performance drops away.

The governing body additionally considered the impact of increased top speeds on the approach to Monaco’s tight and unforgiving corners.
