F1 active aero system dropped for Monaco

F1’s 2026 regulations introduced adjustable front and rear wings that can switch into a low-drag configuration on straights before reverting to a higher-downforce setup through corners.

The system was designed to improve aerodynamic efficiency while also helping manage the demands placed on Formula 1’s new-generation power units.

Unlike DRS, which was primarily introduced as an overtaking aid, straight mode is intended to reduce drag and improve energy efficiency rather than directly promote passing.

Monaco’s tight street layout has ultimately led to the FIA ruling out its use for the weekend, with the official track map published on F1.com confirming there are no straight mode activation zones anywhere around the Monte Carlo circuit.

That makes Monaco the first round of the 2026 season to run without the feature.

According to The Race, the FIA’s guiding principle for 2026 has been to avoid deploying straight mode in areas where cars are heavily loaded under braking, acceleration or cornering, due to the potential impact on stability.

That requirement becomes particularly significant in Monaco, where the lap is defined by constant transitions between low-speed corners, heavy braking zones and traction-limited exits.

The FIA has also set a minimum duration threshold of more than three seconds for any activation zone, aimed at preventing short bursts of use that add driver workload without delivering meaningful performance or efficiency gains, with safety considerations also influencing the decision, The Race added.

With straight mode capable of significantly reducing drag and increasing top speeds, concerns were also raised about cars arriving at Monaco’s tight corners with reduced margin for error.

While Monaco previously featured a single DRS zone on its start-finish straight, F1’s new system will not be used anywhere on the circuit across the 2026 weekend. DRS was never used through the tunnel due to safety concerns.

Drivers will still have access to F1’s new overtake mode in Monaco, with the detection point set before Rascasse and activation occurring on the run to the final corner.
