Piastri: McLaren faster in Hungary? The energy paradox of F1 2026

Oscar Piastri has just revealed an astonishing fact: McLaren's simulation shows that the 2026 car will have lower top speed on the main straight at Monza than at Hungary. This completely defies conventional logic – Monza is the fastest track on the F1 calendar, with over 80% full throttle, while Hungary is a slow, twisty circuit. So how can a car be faster in Hungary? The answer lies in the energy revolution that F1 is about to enter from 2026. The new 2026 power unit regulations mark the biggest change since the 2026 hybrid era. The internal combustion engine (ICE) and electrical system will share power almost 50-50, with approximately 400 kW from ICE and 350 kW from electricity. This means electrical energy becomes the decisive performance factor, rather than just a supplement. However, to ensure sustainability and safety, the FIA has limited energy recovery to 4 MJ per lap – a much lower figure than other options. This limit creates an energy paradox. At Monza, with long straights, the car needs a lot of energy to maintain high speed. But because only 4 MJ per lap can be recovered, the usable electrical energy is severely restricted. As a result, McLaren's simulation shows the top speed on Monza's main straight is even lower than at Hungary – where there are more corners, allowing better energy recovery. Piastri describes this as a "no-win trade-off": if the recovery limit is raised, the car suffers from "super clipping" – the electric motor suddenly decelerating to harvest energy, costing 30-40 km/h at the end of each straight. If the limit is lowered, the car lacks energy to accelerate. Super clipping is one of the most controversial issues of the 2026 regulations. When a driver is at full throttle, the electric motor can still apply negative torque to recover energy, causing sudden deceleration well before the braking zone. Drivers dislike this because it disrupts natural driving feel. Piastri admits that with the 4 MJ limit, clipping has been reduced to a "normal-ish" level, but the cost is lower speed. He says: "No matter which way you go, you lose something. I think this is the correct direction, but it will create chaotic races, especially at the start." These chaotic races Piastri calls "yo-yo racing" – where each car's speed constantly changes depending on battery state. A car with more energy can easily overtake on the straight, but then gets overtaken again when the battery depletes. This leads to another controversial phenomenon: "unearned overtaking." Piastri points out that different approaches to harvesting and deploying energy have already produced more overtaking this season, but much of it is due to energy differentials rather than driver skill. At Monza, where straights dominate, this effect will be even more pronounced. F1 CEO Stefano Domenicali has a different view. He insists fans don't care about energy management: "Overtaking is overtaking. Many people think a clip is something you put in your hair." However, the gap between technical and commercial perspectives is creating tension. The FIA wants drivability and safety, while FOM fears low speeds and chaos will reduce the sport's appeal. Strategically, energy management will become the decisive factor instead of tires or pit stops. Teams will need to develop detailed energy deployment maps for each corner, and drivers will need excellent technical communication skills to optimize performance. Piastri, with his sharp analytical ability, is showing his value in this new context. McLaren has also invested heavily in energy simulation, which could provide a competitive advantage. However, the risks are significant. If Monza speeds are too low, the FIA may have to adjust the recovery limit before the 2026 season starts. If "unearned overtaking" becomes widespread, the value of driver skill will be questioned. And if fans don't understand what's happening, their engagement with the sport may decline. Despite this, Piastri remains optimistic: "I think we'll see extraordinary races. Maybe chaotic, but that's F1." This quote captures the spirit of the 2026 regulations: embrace uncertainty and find appeal in chaos. Will fans keep up? Only time will tell. But one thing is certain: F1 is entering a new era where energy, not just speed, is king. This article is based on in-depth analysis from McLaren and Oscar Piastri sources, combined with a sociological perspective on power shifts in motorsport. It is one of the most fascinating technical stories I have followed, and I believe it will shape how we view F1 for years to come.
