Why 2026 F1 AI engine deployment control is a mess
Drivers are furious at the Hungarian GP as the self-learning power unit debate hits boiling point before a single lap is run.
The debate over 2026 F1 AI engine deployment control has exploded at the Hungarian Grand Prix media day, and it is dominating every conversation in the Budapest paddock. Drivers are frustrated, fans are confused, and the engineers are still scrambling for answers.

Why 2026 F1 AI engine deployment control frustrates drivers
Following the race weekend at Spa-Francorchamps, and particularly Oscar Piastri‘s strong comments, one topic dominates media day in Budapest: energy management, more specifically the self-learning aspects of the 2026 power unit.
McLaren team principal Andrea Stella explained that the 2026 power units feature self-learning elements, allowing them to learn from lap to lap and even throughout a lap in order to anticipate energy management requirements. These algorithms actively learn from each lap and even from out-laps, adapting their energy deployment strategies in real time. The systems are so sensitive that tiny differences in driver inputs, such as lifting the throttle a fraction too late or applying more than 60% throttle at the wrong moment, can trigger unpredictable behaviour.
Extremely small differences in driver input can affect energy management later in the lap, but the same applies to factors completely outside a driver’s control, such as changes in wind direction or grip levels. Drivers are having to adjust their inputs dynamically to compensate, and the way these AI power units respond is so unpredictable that many drivers are struggling to make those adjustments correctly, feel them, or even know the degree of adjustment required.
Insiders who spoke with RNT Motorsports confirm that drivers in many situations can barely make a difference at all. The problem runs deeper than car setup or track conditions. When a self-learning system decides where energy is deployed or harvested, and that decision can change every single lap, the driver is simply no longer in control. Talents like Kimi Antonelli, Fernando Alonso, Max Verstappen and Lewis Hamilton cannot attack a corner in their own way if the software is dictating what happens next.
Piastri calls it “crap”, and he is not wrong
Piastri put it bluntly: “When you’ve got qualifying grids decided by computers behaving or misbehaving, it’s a pretty crap way of going racing. Here it’s obviously exaggerated a lot and made worse, but yeah, when you come in from a qualifying session, you look at all the corners and go, ‘I’m on par with my team-mate and yet I’m two tenths behind at the end of it’. It’s not a very nice feeling.”
Piastri stressed that the problem “has to do with how the engine is calibrated, how the engine learns, it’s kind of ingrained into these engines.” Worryingly, there is not a short-term fix in sight, according to Piastri.
You can see exactly why the Mercedes deployment problem at the Belgian GP hurt so badly, and why Russell’s battery failure ruined his Belgian GP. The issue is not team-specific. It is baked into the regulations themselves.
Verstappen says the fastest drivers are being penalised
Speaking ahead of the Hungarian Grand Prix, Max Verstappen said others were now recognising the problems he had warned about before the regulations arrived. “It’s just your throttle input. By being faster sometimes in the corner, you lose more in the straight afterwards, which, of course, is not how it should be.”
According to Verstappen, that is exactly why many team-mates have been so closely matched this year and why the fastest drivers can no longer fully showcase their talent. “It’s basically just neutralising a lot of lap time, and that’s why, in general, you see a lot of close battles between teams and also team-mates, because sometimes you cannot make a difference. You’re not allowed to make a difference because it will just penalise you on the next straight.”
Sources with knowledge of the situation confirmed to RNT Motorsports that this is the core of the frustration: a driver like Verstappen, who is exceptional at carrying speed through fast corners, is being structurally punished by a system that then deploys less energy on the exit. His strength becomes a weakness. That is a fundamental problem for the sport.
We have also previously covered why the Verstappen McLaren visit at the Belgian GP matters in the bigger picture of his future, and the pressure of these regulations only adds to that story.
Norris fires back: “It’s what we’re paid millions for”
Lando Norris pushed back in Hungary. “I’ve had to change my driving style every single year of my life,” he said. “If you’re not ready to adapt to a different car, then you’re not at a good enough level. It’s our job, it’s what we’ve got paid millions to do. It’s to drive any car you get given, whether it’s a good one, a bad one, an easy one or a hard one. You have to do it.”
That is a fair point from Norris. But it does not fully answer the question Piastri and Verstappen are raising. Adapting to a harder car is one thing. Having no 2026 F1 AI engine deployment control at all is another.
Why Hungary might ease the 2026 F1 AI engine deployment control debate
At the Hungaroring, the self-learning issues should be much less of a factor than at Silverstone and Spa, as the circuit near Budapest is energy-rich. The Hungaroring’s short straights and predominantly slower corners place less emphasis on prolonged electrical deployment. That matters under the 2026 engine regulations.
According to insiders who spoke with RNT Motorsports, the many short sections between corners at the Hungaroring mean there is more energy available for the system to harvest and redeploy. The AI still decides where that energy goes, but the margin for error is smaller than at a power circuit like Spa. That said, it does not change the bigger picture: when the algorithm decides the deployment, the driver is not truly in charge.
The circuit just outside Budapest is energy-rich, meaning there will be far less discussion about energy management in the paddock than over the previous two race weekends. That is a refreshing change and also means the cars will be tested in different ways, with much greater emphasis on chassis performance.
