DRS no longer appears in the 2026 F1 regulations. How activation zones, gap window and Overtake mode work, and how you prepare them in the simulator.
The honest answer up front: A "DRS use", as many still have it in their heads, is no longer in the 2026 F1 regulations. The word does not appear in the parts of the regulations we read (Sporting Issue 09, Technical Issue 20) [1][2]. Instead there are two systems you need to keep apart: the adjustable bodywork (front and rear wing) and the Overtake mode (additional electrical power).
Why is this a pro topic? Because both depend on conditions you must have in your head before the race: activation zones, detection line, gap window, track state. The regulations do not fix these values themselves but have the FIA publish them at the latest four weeks before the competition [1].
Scientifically, there is no study on these systems. We can support that the decision to overtake is made under extreme time pressure and is called "overtake-ability" in research [3]. Everything technical below comes from the regulations and is marked as a regulation source (Tier B). How you use it in practice in the paddock is coaching practice.
Realistically: you do not learn this on track but in the simulator and in briefings, long before you drive such a car.
The adjustable bodywork: front and rear wing switch between two fixed positions, "Corner Mode" and "Straight Mode" [1][2]. They may only be in the Straight position inside an activation zone [2]. The Overtake mode is the additional electrical power of the hybrid system [2]. Both are regulated separately.
Milestone: You explain the difference in two sentences without saying "DRS".
Before each competition the FIA publishes activation zones, detection line, activation line and the gap window (Detection Gap), at the latest four weeks beforehand [1]. The start of each zone is signposted at the track [1].
Milestone: You sketch zones and lines of your track from memory.
In the race: whoever crosses the detection line less than the gap window behind another car gets Overtake mode at the activation line. Whoever was further away does not get it there [1]. In qualifying it always applies when it is enabled [1].
Milestone: You explain why a run (slipstream) before the detection line counts and not just after it.
Behind the Safety Car the Overtake mode is switched off, as it is in low grip conditions and by decision of the Race Director [1]. In low grip only partial activation of the bodywork in its own zones is allowed [1].
Milestone: You name the three cases in which the system is off.
The extra power mainly works at high speed. By the formula in the regulations the electric motor may deliver at most 100 kW at 340 km/h without Overtake, and 300 kW with Overtake. And the assistance runs up to 355 km/h instead of 345 km/h [2]. So you get ten kilometres per hour more headroom at the top.
Milestone: You plan your straight so that you use the system where it works, not where you have it.
Calculate your overtaking chance backwards: from the activation line to the braking point, then back to the detection line. That way you know while measuring how much gap you need. Perceiving the overtaking chance is a decision under time pressure [3], and the more you calculate beforehand, the less you have to decide in the situation.
In the 2026 F1 regulations we read the term does not appear [1][2]. Instead there is adjustable bodywork in activation zones and Overtake mode. For lower formula series their own regulations apply, which we have not read.
An additional power of the hybrid system that the driver may only use if it is enabled and activated [1]. In the race it depends on the gap to the car ahead at the detection line [1].
Behind the Safety Car, in low grip conditions and by decision of the Race Director [1]. Before the race start it is also off until the leader has crossed the detection line for the first time [1].
The transition time between the two positions may be at most 400 milliseconds, so less than half a second [2]. The regulations only set the upper limit.
Only in the simulator or in series that use such systems. Check the regulations of your series. This guide explains the logic so you understand it in radio calls and briefings.
