The FIA has reversed course on Albert Park’s fourth Straight Mode activation zone, reinstating the Lakeside Drive section from Turns 6 to 9 just hours after telling teams it would be removed on safety grounds.
On Saturday morning in Melbourne, teams were informed at 9:45am local time that the zone — threading through the quick, curving run around the back of the lake — would be taken out for the remainder of the weekend. That decision followed a drivers’ meeting with the FIA on Friday night where concerns were raised about how the 2026 cars behave when switching into Straight Mode through that sequence.
But by late morning, the governing body had changed its stance again.
“Following the feedback received in the last hour from Teams and Drivers, and additional analysis contributed by Teams, the decision to remove Straight Mode zone #4 for Albert Park is rescinded,” the FIA said in a statement. “For the avoidance of doubt, this amendment is effective immediately, and Straight Mode activation Zone 4 will be in used in FP3. Further evaluation will take place during and after FP3.”
The flip-flop has underlined a familiar reality of this new rules cycle: the FIA can model, simulate and assume plenty — but it’s still learning, in real time, how each team’s interpretation of the regulations changes the car beneath the driver when the systems switch state.
The issue, as FIA head of single-seaters Nikolas Tombazis explained, wasn’t simply that Straight Mode is faster. It’s how abruptly the car’s aerodynamic platform shifts when it’s activated — particularly through a high-commitment section where the driver is already asking a lot of the front axle.
“From our perspective, it seemed quite aggressive choice to have straight mode through those fast sweepers,” Tombazis said. “We have three parameters that are relevant.
“One is the overall downforce of the cars following many months of development. The second is what percentage of that downforce gets lost on straight mode. The third parameter is, what [is the] balance shift? So how much more is the front downforce reduction compared to the rear downforce.
“We had assumptions for all of these three parameters for I think it’s about seven of the 11 teams. So for a big proportion, the downforce they had on the front wheels following those three parameters was less than we had anticipated and made what looked like a safe choice transpired to be unsafe.”
That last line is the key. Straight Mode isn’t a simple drag reduction button in the old sense; on these 2026 cars it’s a broader “state change” that can move the centre of pressure and trim the car’s stability at precisely the moment you least want surprises. Drivers, understandably, don’t love discovering mid-corner that the front has gone light because a system has switched, especially at a track lined with walls and punctuated by quick direction changes.
The FIA’s initial response was cautious — remove the zone and eliminate the risk. Teams’ response, judging by the speed of the reversal, was more nuanced: supply extra data, push back on the need for an immediate blanket solution, and emphasise that the picture varies car-to-car. Some will have designed in a gentler balance migration when Straight Mode is engaged; others, as Tombazis all but admitted, have produced a sharper front-end drop than the FIA assumed when it signed off the activation maps.
Reinstating the zone “effective immediately” for FP3 reads like a compromise born of urgency. The FIA gets another live session to evaluate the behaviour with the benefit of added team analysis, while avoiding a last-minute sporting change that would ripple through run plans and compromise an already frantic weekend of learning for everyone.
It also sets a tone for 2026: expect more of these track-by-track arguments about where Straight Mode should and shouldn’t be allowed. Albert Park, with its fast sweepers and changing radii, is exactly the sort of circuit that exposes the grey areas. Today it’s Zone 4 at the lake; later in the season it’ll be a different corner, a different surface, a different set of complaints — and a different team quietly confident it can gain if the zone stays in.
For now, the message is simple. The zone is back for FP3. The FIA will watch, measure and talk again afterwards. And in the background, the sport is being reminded that the 2026 cars don’t just need to be quick — they need to be predictable when the driver asks them to change mode at 250km/h while turning.
