FIA outlaws active aerodynamics for Monaco GP on safety grounds

The FIA has officially decided that Formula 1’s new active aerodynamics system will not be used at next week’s Monaco Grand Prix, with safety concerns forcing a significant rule adjustment for the most famous street race on the calendar.

Teams will run without “straight mode” – the low-drag aero setting introduced on the 2026 cars – after fears emerged that the cars would reach dangerously high speeds exiting Monaco’s Tunnel section, where run-off areas are severely limited.

The decision means the Monaco weekend will feature fixed front and rear wings throughout, removing one of the defining technical features of the current generation of Formula 1 machinery.

Consequently, there will also be no DRS-style overtaking aid available, creating a very different challenge for teams and drivers around the tight Monte Carlo streets.

The FIA’s move is viewed internally as a precautionary step, prioritising safety over performance gains at a circuit already regarded as one of the sport’s most unforgiving venues.

Without straight mode reducing drag on the straights, teams are now expected to fully commit to maximum downforce setups – a dramatic shift from the low-drag philosophy that has shaped much of the 2026 season so far.

Monaco could shake up competitive order

The change potentially opens the door to a more unpredictable weekend.

Mercedes has dominated the season to date, with George Russell and Kimi Antonelli sharing all five grand prix victories between them. However, Monaco’s unique demands may narrow the gap to rivals.

Ferrari is expected to benefit most from the altered conditions. While the SF-26 has struggled for outright engine performance, it has consistently shown strong chassis balance and aerodynamic performance through slower corners – precisely the characteristics needed around Monaco.

McLaren could also emerge as a serious threat. The Woking-based team’s short-wheelbase MCL40 is naturally suited to tight, low-speed circuits, and the absence of active aero may reduce Mercedes’ usual advantage.

With overtaking notoriously difficult in Monaco, qualifying is once again expected to define the race weekend. Teams are now exploring whether bespoke high-downforce solutions could offer a decisive edge on a circuit where tiny gains can transform the grid.

However, with cost-cap restrictions limiting how aggressively teams can develop one-off components – and with little notice before the Monaco weekend – some outfits may be forced into something far less scientific: old-fashioned guesswork.

Engineers could end up relying on simulations, legacy setups and educated instinct rather than fully optimised aero packages specifically designed for the Principality.

For Formula 1’s engineers, Monaco has suddenly become far more than just another race weekend – it is now a one-off technical puzzle.
