The FIA removed a Straight Mode activation zone in the high-speed lakeside middle sector at Albert Park for the remainder of the Australian Grand Prix weekend after drivers raised safety concerns that low downforce in traffic could cause loss of control, including front- and rear-end sliding. Sources variously described the deleted zone as covering Turns 6–9, 7–9 or the esses at 8–9; teams were informed of the change at 9:45 a.m. on Saturday, just over two hours before FP3. FIA single-seaters head Nikolas Tombazis said the Straight Mode had been an “aggressive” choice and emphasized “safety is number one,” while officials called the full removal a blunt or “draconian” but provisional, safety-driven measure.
The FIA said overnight simulations and analysis of data from all 11 teams — which showed seven teams had less front-axle downforce than expected — supported the decision, and it noted it may seek other interventions such as imposing minimum downforce levels pending further data. Officials said they considered shortening the zone but judged that option too risky and described the removal as a blunt, all-car solution because the Straight Mode effect varied between car designs; they plan to analyze more data after the first two races to find less blunt options.
The late change forces technical and strategic revisions: cars will now carry Corner Mode wings through the former Straight Mode sector, increasing aerodynamic drag and forcing teams to rework aerodynamic setups, ride heights and tire plans on short notice. Reduced entry speeds into Turn 9 will shorten braking zones and cut opportunities to recharge batteries, meaning energy-recovery and battery-deployment strategies must be revised; officials warned energy recovery through the sector will be harder and the change will reshape race and qualifying strategy under the new rules. The intervention comes at the first event run under the 2026 technical regulations, which replace DRS with a five-zone active-aero Straight Mode system that opens bodywork on long acceleration stretches to reduce drag and automatically closes for corners; the 2026 rules also removed the MGU-H, introduced an Overtake Mode battery boost and added a five-second pre-start turbo build-up delay. Early running at Albert Park showed several manufacturers demonstrating promise while others faced problems, underscoring that the Straight Mode removal will have immediate implications for teams adapting setups, energy management and strategy across the rest of the weekend.
