One-second gap
A driver must usually be within the required gap at a detection point to use DRS in the following activation zone. The timing point matters more than the gap shown later on the straight.
DRS made modern F1 overtaking easier to explain: be close enough at a detection point, then open the rear wing in an activation zone. The 2026 rules add a new conversation around active aero and electrical deployment, so overtaking will not be only a rear-wing question.
DRS is a regulated drag-reduction aid, not a free button drivers can use anywhere.
A driver must usually be within the required gap at a detection point to use DRS in the following activation zone. The timing point matters more than the gap shown later on the straight.
DRS can only be opened in designated zones and only when race control has enabled it. It is usually disabled at the start, after restarts, or in unsafe conditions.
A driver can use DRS if they qualify for it, even if they are defending from another car while following someone ahead. That can create DRS trains.
The 2026 car concept includes active aerodynamic states and greater emphasis on electrical deployment. That means an overtake can depend on drag level, battery use, and manual override rules rather than only a rear-wing flap.
