In the wake of Formula 1's 2025 pre-season testing at Bahrain, suggestions were abound that a handful of teams suspected that their rivals had employed some form of "mini-DRS" on the straights.
Video footage emerged on social media of Mercedes' rear wing appearing to tilt back at high speed. Other footage shared appeared to point at McLaren's outboard slot gap expanding at high speed before closing up in the braking zone. Ferrari has also been suspected of using "mini-DRS" trickery in Bahrain.
