Piastri: McLaren 'quicker on the front straight in Hungary' than at Monza

When Oscar Piastri sat in McLaren's simulator at Woking, he saw a paradox that no data sheet from the current era could explain: his 2026 car, fitted with the low-drag H-wing designed specifically for Monza, had a lower top speed on the main straight than at the Hungaroring. A 5.793-kilometer circuit with nearly 80% of the lap at full throttle — where speed is king — was being beaten by a stop-start track like Budapest. This is not a software glitch. This is the nature of the 2026 engine regulations.

The F1 community is still used to the old story: Monza is where low-wing cars blast through, where internal combustion engine power is displayed like a medal. But from 2026, nearly 50% of the power will come from the electrical system, and the FIA has cut the energy recovery limit to 4 MJ per lap — a figure that Piastri describes as leaving the car 'energy-starved' on long straights. In the current hybrid era, teams can recover energy at higher rates, creating 'super clipping' — when the electric motor reverses to charge the battery, causing the car to decelerate suddenly even when the driver is at full throttle. Piastri estimates this could cost '30 or 40 km/h at the end of each straight'.

The FIA's decision — cutting to 4 MJ per lap — is a deliberate trade-off: reducing 'super clipping' to improve drivability, but simultaneously strangling top speed. At Monza, where braking zones and low-speed corners are insufficient to regenerate the energy consumed on long straights, the result is a structural energy crisis. Piastri told media at Monza: 'Our car is quicker on the front straight in Hungary than here.' A seemingly absurd statement, but an accurate diagnosis of a systemic technical problem.

As I followed McLaren's simulator sessions, I realized this is not just a story about one team. The entire concept of strategy at Monza will be overturned. In the past, strategy revolved around tire management and pit stop timing. In the future, it will revolve around battery state management. Piastri predicts 'there will be chaos, especially at the beginning' — because drivers will be at different energy states at different times, creating overtaking moves that he calls 'unearned' — not due to driving skill, but due to differences in battery charge levels.

I used to believe in the data sheet, until the data sheet was torn apart by a counter-attack. Here, the top speed data sheet at Monza has been torn apart by an energy regulation. And here's the blind spot that few see: if top speed is limited by available energy rather than aerodynamic drag, then running an extremely low-wing package like the H-wing may become pointless. Teams may have to run more downforce than drag-optimal, to reduce full-throttle time and create more energy recovery opportunities. This inverts decades of Monza aero philosophy.

Of course, I could be wrong. All this data comes from simulations — no 2026 car has run on a real track yet. There's a chance teams will find sophisticated ways to optimize energy maps, or the FIA will adjust the 4 MJ limit before the season starts if top speeds become unacceptable. But one thing is certain: the debate between the FIA and FOM over whether fans care about energy management — with F1 CEO Stefano Domenicali insisting 'overtaking is overtaking' and mocking that 'many people think a clip is something you put in your hair' — will not solve the real-world problem on track.

The stranger doesn't need a ticket; they open the door with their own feet. And in the new era, that stranger is electrical energy — the force that will decide who wins and loses at Monza 2026. The question is no longer 'who has the most powerful engine?' but 'who manages the battery smartest?' From contempt to respect — that is the longest journey F1 can give us. And we are about to embark on it.
