Problem for F1 teams? Doubts over feasibility decree for wing

The FIA announced this Monday it had issued a directive on the use of the so-called mini-DRS. Ho-Pin Tung, former driver and current analyst, questions whether a real adjustment has been made here.

In a statement earlier today, the FIA wrote about the rule change: "Specifically, Article 3.15.17, introduced in 2025, states that if 75 kg of vertical load is applied to both ends of the mainplane of the rear wing, the distance between the mainplane and the flap (also known as "slot gap") should not vary by more than 2 mm. From the upcoming Shanghai Grand Prix, this limit will be reduced to 0.5 mm."

Ho-Pin Tung, former test driver for Williams, Sauber and Renault, wonders if this is all feasible from next weekend. The Dutchman, who races under a Chinese licence, calls the adjustment on X "very significant".

"Especially with fly-away races, I can't imagine teams having (brought) "safe" wings. This may come as a big surprise. To be continued, no doubt," Tung wrote.
