When asked whether they were satisfied with the technical and sporting changes after the opening three races of the season, Oscar Piastri and Sergio Pérez both made clear that the revisions were necessary and overdue.

Among a series of technical changes for the Miami Grand Prix, the FIA has also introduced a new cap on Boost power in race trim. Boost is now limited to an additional 150 kW, or the car’s current power level at activation if that value is higher. This measure is designed to prevent the dramatic performance swings that contributed to several near‑misses and one major accident in the early rounds.

The MGU‑K will still deploy at 350 kW in key acceleration zones, but elsewhere, deployment will be restricted to 250 kW. This dual‑level model aims to reduce excessive closing speeds without eliminating overtaking opportunities.

Tombazis acknowledged that the collision between Oliver Bearman and Franco Colapinto at Suzuka accelerated the need for action. He stated that “the type of problem we saw with Oliver Bearman’s accident at Suzuka should be essentially avoided starting from the next race in Miami.”

A further change concerns the inconsistent torque delivery seen at several race starts this season. To address this, the FIA has introduced a “low power start detection” system. If a car fails to accelerate normally after clutch release, the system will automatically intervene to ensure the car moves off safely.

Tombazis explained that “on the risks at race starts, it will probably take two or three Grands Prix to implement all the changes, but we will already carry out some tests in Miami and Montreal, putting a safety net in place.” He added that “if it is detected that a car has an extremely problematic start, the electrical system will activate and take control, ensuring that the car moves off safely to avoid risks for the drivers behind.”

When asked whether they were satisfied with the changes and whether they felt listened to, Oscar Piastri and Sergio Pérez both made clear that the revisions were necessary and overdue.

Piastri explained that the discussions intensified after the Suzuka accident, saying: “There were a lot of ideas after Suzuka, and I think clearly after Ollie’s crash it’s pretty obvious that something needed to change. I think it’s been good that they’ve listened and made changes.”

He emphasised that the adjustments were well considered: “As I said before, really there’s only so much you can do, and I think what we’ve tried to change within our control has been good and has been sensible and I think well thought out.”

However, he cautioned that the real impact will only become clear on track: “So yeah, that’s been a positive. But we’ll have to wait and see how it pans out. In the simulator running I did, some things are a bit better, some things are really not very different, so we’ll have to wait and see just how it turns out on track.”

From a safety standpoint, Piastri strongly supported the Boost‑related changes: “I think the changes with the boost button are sensible and in the right direction.

"Hopefully you can’t eliminate the instances of people having 350 kilowatts more than another car at all times, but hopefully it reduces the amount of times that happens.”

Pérez echoed Piastri’s concerns, stressing that the Suzuka crash highlighted the need for immediate action. The Mexican said: “Yeah, obviously what happened in Suzuka was very scary and from a safety point of view there was urgency to change things.”

He welcomed the collaborative approach across the sport: “And for me it’s very good to see that we are open for changes in all areas: drivers, teams, FIA, Formula 1. So that’s good.”

Like Piastri, Pérez noted that the true impact of the changes will only be understood once cars run in competitive conditions: “And like Oscar says, we really need to see how are those changes once we are in race conditions, qualifying conditions, because it’s very difficult with these rules to predict anything.”

He also suggested that further adjustments may follow: “So, the best thing of it is that we are open to it and if there are more changes needed after this weekend, I would expect to… There is also a big gap before Canada, so probably we can do even more changes if needed.”
