The brand new-generation of Method 1 vehicles have modified how Suzuka’s first sector is tackled: past the decreased downforce, which lowers cornering speeds, drivers now barely contact the brake pedal, as a result of the hybrid system decelerates the automotive by transitions to maximise power restoration in a key part.
Through the years, Suzuka has fascinated due to the fantastic thing about its format, with medium- and high-speed corners able to taking the breath away from each drivers and followers watching from house. Nevertheless, with the arrival of the brand new energy items, the challenges have modified radically in comparison with the previous—and, because of this, so has the driving fashion at Suzuka, maybe extra noticeably than at different circuits.
The primary issue is that the Japanese observe doesn’t function many heavy braking zones, which limits alternatives to constantly recharge the battery as a way to handle the various acceleration phases—a few of which, furthermore, can’t even profit from DRS for security causes. For that reason, not less than for qualifying, the FIA has determined to scale back the utmost recoverable power from 9 MJ to eight MJ.
This could cut back the quantity of lift-and-coast and super-clipping, however it’s clear that groups should nonetheless maximise the accessible 8 MJ, figuring out the place and easy methods to harvest it. So the place is that this power recovered? Probably the most fascinating level lies in understanding what occurs within the first sector. Already final yr, following resurfacing, grip ranges had elevated, permitting drivers to push with increased cornering speeds.
This yr, nonetheless, the state of affairs has partly reversed. Firstly, these new vehicles generate much less aerodynamic downforce, so sustaining the identical tempo—particularly by medium- to high-speed corners the place ground-effect vehicles beforehand excelled—is harder. However there’s additionally a second issue: how the brand new energy items have modified the best way this part is approached, one thing already anticipated when discussing the impression of getting solely two energetic aero zones.
That is evident already on the entry to the Esses, the place clear velocity variations between groups emerge. It’s not nearly downforce, however about how a lot power is used exiting Flip 2. Some drivers preserve power, given the quick straight that instantly leads into the sequence of corners; others take a extra aggressive method, spending extra power early to hold increased velocity into the part.

Very completely different driving kinds—however much more fascinating is how the MGU-Okay is now used by transitions as a real braking system. It not solely helps decelerate the automotive and cut back understeer, but in addition recovers power to be deployed later within the lap. This isn’t fully new, however with an MGU-Okay now able to delivering and harvesting thrice the ability, the impact is way extra pronounced.
Naturally, groups that had excessive downforce final yr, corresponding to Pink Bull and McLaren, tended to rely much less on braking. These with a deficit, like Ferrari and Mercedes, needed to work each pedals to compensate for decreased front-end grip and assist the automotive throughout turn-in and mid-corner phases.
Utilizing Ferrari as a reference—given its relative continuity between 2025 and 2026—it’s clear that on this part the brake pedal is barely touched. The MGU-Okay performs many of the braking work, slowing the automotive and aiding rotation with out requiring driver enter on the pedal.
Sections that have been taken in sixth gear final yr are actually approached roughly 30km/h slower, in a decrease gear and with much less throttle, regardless of sustaining excessive engine revs. This alteration mustn’t come as a shock: the FIA has established that from Flip 3 to Flip 6, energy discount can exceed 150kW, and this has two results.
First, in sure areas, even with the driving force on the throttle, the MGU-Okay doesn’t deploy energy however stays in harvesting mode. This occurs as a result of the limiting issue isn’t engine output, however grip and aerodynamic load—so the FIA permits groups to successfully “zero” electrical deployment and let the MGU-Okay proceed recovering power with out contributing to propulsion.
This permits power to be saved for later sections and, not surprisingly, vehicles have been seen exiting Flip 6 with extra power than that they had at first of Flip 3. In apply, the habits resembles “one-pedal driving” seen in street vehicles: when the driving force lifts off the throttle, the electrical motor each recovers power and generates a braking impact.
This represents a totally new approach of tackling this part. It doesn’t seriously change the driving force’s intuition when it comes to throttle modulation, however it essentially alters what occurs underneath the hood: the electrical motor is used in a different way and finally ends up virtually fully changing the mechanical brakes. “It’s not a catastrophe, however it’s not like earlier than. F1 shouldn’t be like this,” mentioned Sainz on the matter.
The method to 130R has additionally modified. In actuality, the cornering velocity isn’t very completely different from the previous, however it’s reached otherwise, with velocity dropping because the automotive goes into derating as a result of lack of electrical motor assist. Peak speeds are reached earlier—over 20 km/h increased, additionally due to DRS—however after that peak there’s a lengthy deceleration part, shedding greater than 50 km/h earlier than braking for the chicane.
