The FIA has officially presented the upcoming cycle of regulations. The Formula 1 cars of 2026 will differ in many ways from the current ones, and one of the most interesting aspects is active aerodynamics. This solution will allow the cars to dynamically change their aerodynamic configuration. In particular, two different modes will be available. But let’s go step by step.
What is Active Aerodynamics?
To begin with, an element of active aerodynamics already exists in the current generation of cars: the DRS. In general, active aerodynamics refers to an aerodynamic profile (front and rear wings) whose angle can be varied at any time via an actuator. What we will see in 2026 will be a significant evolutionary step compared to the current DRS.
What will the aerodynamics of the 2026 F1 cars be like?
In 2026, not only the rear wing will be mobile but also the front wing. It will be possible to switch between two aerodynamic configurations: X Mode and Z Mode.
X Mode is the low-downforce, low-drag configuration to be used on straights. Z Mode is the high-downforce configuration to be used in corners for higher cornering speeds.
The new rear wing will have three elements with significantly simplified endplates. The front wing will be 100mm shorter and will feature an active two-element flap.
Another significant difference compared to current cars will be the wheel arches. The front wheel arches will no longer be present, but it will still be mandatory to have some geometry on the wheel to reduce the wake generated.
The aerodynamic philosophy will shift to in-wash. This aims to keep the airflow inside the car, reducing the dirty wake. In theory, this should make it easier to follow the car ahead.
Return of the Flat Floor
Another departure from the current generation of cars will be the floor. The 2026 cars will return to having a partially flat floor with a reduced diffuser.
This choice was made to reduce ground effect and thus avoid overly low and stiff setups. The main goal was to eliminate porpoising. This will significantly reduce the downforce generated by the car’s floor. The 2026 cars will have 30% less downforce but also 55% less drag.
What are the advantages of active aerodynamics?
The key aspect of this solution is the variable angle of the wings. This allows for a significant improvement in vehicle efficiency.
On straights, the wings will be set to a very low downforce configuration, drastically reducing drag. During braking or when the driver lifts off the throttle, the profiles will revert to a high downforce angle, creating downforce again and stabilizing the car, allowing the driver to carry high speeds through corners.
Additionally, active aerodynamics will complement the new power units. X Mode on straights will drastically lower drag, thus also reducing the power unit’s fuel consumption.
