The Suzuka race highlighted why the 2026 Method 1 laws can each create thrilling races – due to hybrid power deployment methods that trigger near-constant passing – but additionally what the crucial points are that want addressing, beginning at subsequent week’s assembly between F1, the FIA, and the groups.
Exactly due to this dynamic of overtakes and counter-overtakes, the Japanese race additionally supplied an opportunity to look at how sure behaviours of the advanced new energy items can have an effect on how drivers should deal with their automobiles – nearly unnaturally – forcing them to adapt extra to power administration logic than to intuition.

That is one thing that additionally impacts qualifying, and it’s one of many causes many drivers have identified that it’s now extra advantageous to remain under the restrict reasonably than take pointless dangers.
The difficulty doesn’t solely concern single-lap tempo, nevertheless; it additionally impacts on-track battles. One of many clearest examples seen in Japan was the struggle between and within the remaining laps.

For the attacking driver, the best selection was typically to make use of power between Spoon and the ultimate chicane. In that part, considerably larger speeds have been reached, whereas the motive force forward tended to undergo a sharper drop when the MGU-Okay stopped offering help, then coming into a recharge part with tremendous clipping.
This dynamic appeared on lap 50, when Norris, utilizing electrical enhance out of Spoon, managed to shut the hole considerably earlier than 130R. He bought so near Hamilton that he needed to raise off at practically 330 km/h – a velocity the place the restrict wasn’t simply slipstreaming but additionally out there grip.

Up thus far, there can be nothing uncommon. The issue arises from what occurred subsequent. Between 130R and the ultimate chicane, there’s nonetheless far, and to keep away from shedding an excessive amount of floor, the pursuing driver has to get again on the throttle. In these conditions – additionally as a result of massive velocity distinction – the chasing driver would favor the facility unit to cut back electrical motor help.

This might nonetheless permit an assault and even finishing an overtake, particularly when the motive force forward, like Hamilton on this case, is in a recharge part with tremendous clipping. It will additionally convey one other benefit: serving to save power for the next straight, the principle straight, the place many counter-overtakes have been seen throughout the race.

Right here’s the place the issue emerges. If 130R is taken flat-out, it means the full-throttle part from Spoon onward is longer and there’s continuity in throttle software. Subsequently, the management unit governing the facility unit follows a selected curve for decreasing MGU-Okay help. But when the motive force is in overtaking mode or utilizing enhance, the second they raise off the throttle, that power discount curve is reset as a result of laws.
In essence, when getting again on the throttle after lifting – as in Norris’ case – the facility unit is pressured by regulation to revive electrical motor help, delivering at the least 200 kW for at the least one second earlier than resuming the MGU-Okay discount curve. This implies the motive force finally ends up with surplus MGU-Okay energy even when it’s not desired, consuming extra power than supposed. This rule was launched for security and to forestall simulating traction management on nook exit, however clearly the state of affairs modifications on the finish of a straight.

That is one thing drivers haven’t any management over. The one technique to keep away from it’s to maintain the throttle absolutely open, stopping the facility unit management system from resetting this “counter” and permitting it to proceed the pure discount of electrical motor energy.

That is what occurred, for instance, to within the early laps, when his engineer instructed him over the radio that, utilizing enhance out of Spoon, he couldn’t afford to raise at 130R. This motion reset the MGU-Okay energy discount course of and price him power when he went again to full throttle for the ultimate part earlier than the chicane.
The issue is that this logic turns into a lot tougher to handle in a battle. In his duel with Hamilton on lap 50, Norris was pressured to raise off additionally to keep away from operating into the driver, who now not had electrical help as a result of he hadn’t activated enhance. At that time, such a big velocity distinction – and the truth that power can be wasted when getting again on the throttle – pushes the motive force towards making an attempt a pressured overtake.
Norris tried to deal with the state of affairs in a different way, partially making use of the throttle as a substitute of going instantly again to full energy. This helps mitigate the impact, but it surely’s clear how unnatural it’s, in a duel, to see a driver nearly pressured into making an attempt an overtake on account of power administration dynamics. The consequence was that he discovered himself with out battery to defend on the next straight.

“The issue is, it deploys into 130R,” Norris defined after the race on Sunday. “I’ve to raise, in any other case I will drive into him, and I am not allowed to return on throttle. If I am going on throttle, my battery deploys, and I do not need it to deploy as a result of it ought to have minimize. However since you raise and it’s a must to return on, it redeploys. There’s nothing I can do about it.”
The treatment in these circumstances can be easy: don’t raise off the throttle. However it’s one factor to do this when driving alone, and one other to handle it in the course of a struggle, the place conditions are unpredictable and it turns into unnatural for drivers to regulate their behaviour based mostly on optimum power deployment.
This isn’t a wholly new subject, however with a 350 kW MGU-Okay able to delivering a lot energy, these conditions carry way more weight than they may appear.
