Why Formula 1’s Straight Mode Will Not Be Used at the Monaco… read more 👇 details in the comments section

Formula 1’s new straight mode has become a key feature of the 2026 season, helping drivers increase top speed on designated sections of the circuit. However, when the championship heads to the iconic Monaco Grand Prix, the system will not be available. For the first dry Monaco race weekend since 2011, drivers will complete every lap without opening their rear wings for a drag-reduction boost.

Straight mode was introduced as part of Formula 1’s 2026 regulations overhaul. Although the sport removed the traditional Drag Reduction System (DRS), it replaced it with a new active aerodynamics package. Unlike DRS, which was primarily designed to aid overtaking and could only be used under certain conditions, straight mode is available to all drivers whenever they reach approved sections of the track.

The system works by adjusting both the front and rear wings to reduce aerodynamic drag. This allows cars to achieve higher speeds on straights, improving efficiency and helping offset some of the aerodynamic compromises required by the new regulations. Throughout the opening races of the season, straight mode has been used successfully at circuits featuring long, clear straightaways.

Monaco, however, presents a unique challenge.

One of the main reasons straight mode has been excluded is the nature of the circuit itself. The streets of Monaco are famously narrow and twist through the principality with very few genuinely straight sections. While the start-finish stretch was previously designated as a DRS zone under the old regulations, it is not considered suitable for straight mode. Drivers still need to make steering inputs along this section before immediately braking for the extremely tight Sainte Devote corner at Turn 1.

The FIA has emphasized that straight mode should only be activated when drivers are not operating at the absolute limit of tyre grip. Deploying the system while a car is still negotiating a bend or requiring significant steering input could increase the risk of losing control. Safety concerns surrounding active aerodynamic systems have been highlighted before, and officials are determined to avoid situations where drivers might be tempted to use the feature in unsuitable areas.

Another factor is the system’s minimum activation requirement. Under the 2026 regulations, straight mode must be usable for at least three seconds to justify its implementation. The rule was introduced to prevent drivers from having to manage the system for only a brief moment while gaining little or no performance advantage.

At Monaco, most straights are simply too short. Even some of the faster sections, such as the run from the Nouvelle Chicane toward Tabac, do not provide enough uninterrupted time for drivers to safely and effectively activate the mode. As a result, the performance benefit would be minimal while adding unnecessary complexity to the driving task.

Safety remains the most significant concern. Monaco is widely regarded as one of the most demanding circuits in motorsport due to its unforgiving barriers and extremely tight corners. Allowing cars to gain an additional speed increase of around 20 km/h before approaching corners such as Sainte Devote, Mirabeau, or the Grand Hotel Hairpin could significantly raise the consequences of any mistake.

The risk becomes even greater in traffic. A slower car exiting a corner or an unexpected obstruction on the racing line could leave drivers with very little time to react if they were approaching at enhanced speeds generated by straight mode. Given Monaco’s limited run-off areas and close proximity of barriers, even minor incidents can quickly become serious.

For these reasons, the FIA has decided that the safest and most practical solution is to disable straight mode entirely for the Monaco Grand Prix weekend. Drivers will therefore rely solely on the standard aerodynamic configuration of their cars as they tackle one of Formula 1’s most famous and challenging venues.

The absence of straight mode is expected to be a Monaco-specific measure rather than a long-term change. The system is anticipated to return at the following race in Spain, where the faster and more conventional layout of the Circuit de Barcelona-Catalunya provides suitable conditions for its use.

While Monaco remains a unique exception, the decision highlights how Formula 1’s new technologies must still be adapted to the characteristics and safety requirements of individual circuits.
