What replaced DRS in F1 in 2026? Learn how active aerodynamics, Overtake Mode and the Boost Button work under Formula 1’s new regulations.
Formula 1 introduced a new approach to overtaking in 2026, bringing an end to the Drag Reduction System (DRS) as fans knew it. Instead of relying on a rear-wing flap that could only be opened when a driver was close enough to the car ahead, the new regulations combine active aerodynamics with additional electrical power to create overtaking opportunities. However, DRS has not simply been replaced by one system. Active aerodynamics reduces drag on designated straights, while Overtake Mode gives eligible drivers an additional electrical advantage when chasing a rival. The Boost Button offers another way to manage power during a fight on track.

What Replaced DRS in F1?
DRS was introduced in 2011 to help drivers overtake by reducing aerodynamic drag. In designated zones, a driver could open a flap in the rear wing when within one second of the car ahead at the detection point. The 2026 regulations separate the two functions previously associated with DRS. Active aerodynamics allows drivers to reduce drag on designated straights, while Overtake Mode provides an additional power advantage to drivers who meet the required proximity conditions. This means a driver no longer needs to be chasing another car to benefit from the straight-line advantages of active aerodynamics.
How Does Active Aerodynamics Work?
Active aerodynamics allows the front and rear wings to change configuration depending on the section of the circuit. In Straight Mode, the wing elements open to reduce drag, helping the car reach higher speeds along designated straights. In Corner Mode, the wings return to their higher-downforce configuration, providing the grip needed to navigate corners.
These configurations are sometimes discussed using the terms X-mode and Z-mode. The underlying principle remains the same: reduce aerodynamic resistance when accelerating along straights and retain sufficient downforce when cornering. Unlike the old DRS system, active aerodynamics is available to all drivers in the designated sections, including those leading a race. This helps manage the balance between straight-line speed and cornering performance throughout a lap.

What Is Overtake Mode in F1?
Overtake Mode is the more direct replacement for DRS as an overtaking aid. It gives a driver additional electrical energy and a different power-deployment profile to help sustain higher speeds when attempting to pass a rival. A driver becomes eligible when their car is within one second of the car ahead at the designated detection point. The system then provides an additional energy allowance of 0.5 megajoules, which can be used to help close the gap or attempt an overtake.
The difference is important. DRS reduced drag by opening a rear-wing flap, whereas Overtake Mode focuses on electrical energy deployment. Active aerodynamics already allows every car to reduce drag on designated straights, so the extra power gives a chasing driver another tool in a close battle.

How Is the Boost Button Different From Overtake Mode?
The Boost Button provides drivers with another way to control electrical power deployment. It can be used to attack or defend, provided sufficient battery energy is available. Unlike Overtake Mode, Boost is not dependent on being within one second of another car at a detection point. Drivers can use it strategically around the lap, depending on their energy reserves, power settings and position on track.
This gives drivers more control over when they deploy their available electrical energy. They might use it to launch an attack on a straight, defend against a rival, or respond to a changing situation during a battle. However, electrical energy is limited. Using it at one point can affect how much remains available later in the lap, making energy management an important part of race strategy.
Will Overtaking Be Easier Without DRS?
The new regulations aim to encourage closer racing, but they do not guarantee more overtakes at every circuit. Active aerodynamics helps cars reach higher speeds on straights, while Overtake Mode creates an additional advantage for drivers close enough to challenge a rival.
The outcome still depends on the circuit layout, available straight-line distance, battery deployment, tyre condition and the performance difference between the cars. A driver can have access to Overtake Mode without necessarily being close enough to complete a pass. The biggest change is that overtaking now depends on a combination of aerodynamic configuration and electrical power rather than a single rear-wing mechanism. Will these systems make wheel-to-wheel racing more competitive throughout the 2026 season?
