According to Jogo Hoje, the clock is already ticking for the 2027 power-unit package. And it’s not the usual “we’ll see” kind of pressure. This is the kind of F1 paperwork-and-physics scramble where the calendar starts dictating the engineering choices, down to how the units of power will actually behave on track.
With the GP do Canadá sitting between May 22 and May 24, F1 is looking to settle—by mid-May, at the latest—whether the 2027 layout shifts away from the current 50/50 balance and toward a 60/40 or even 55/45 split between motor a combustion and energy elétrica. The timing matters because any meaningful change doesn’t just alter numbers on a spreadsheet; it forces hardware, software, and fuel-tank architecture to evolve in lockstep.
What F1 wants to change in the 2027 engines
Let’s get tactical: the debate is about how much the car should “manage” energy versus how much it should simply “drive.” The push gaining steam is a power distribution that makes the motor a combustion more dominant—aiming to bring back a more natural driving rhythm, closer to the feel of earlier generations, without leaning so hard on tools like lift-and-coast, superclipping, and other energy-behaviour tricks that can turn the cockpit into a control-room.
In this context, the proposal being discussed is a move to:
- A possible 60/40 split (combustion/electric), or a softer 55/45 compromise.
- More combustion output, with estimated motor a combustion power rising from 530 cv to roughly 600 cv.
- Boost and recarga de bateria constraints designed to prevent runaway dependence on energy management.
Even though the current regulations already cap key elements, the bigger question is whether the overall balance encourages “racing” or encourages “gaming the strategy.” And right now, the sport is wary of cars that are too dependent on energy orchestration.
Why the proposal gained traction in the paddock
The urgency didn’t appear out of thin air. Reactions to the new power-unit rule package have been mostly negative, and the message from the track has been loud: drivers and teams are dealing with behaviour that feels odd, artificial, and sometimes punishing when it shouldn’t be. Add to that the heavy crash involving Oliver Bearman at the Japanese GP, and you get a paddock that’s less patient than usual.
Plus, F1 had a rare window in April because the Bahrein and Arábia Saudita rounds were postponed, leaving a quieter on-track schedule. In that kind of dead week, meetings get louder. The focus isn’t just on performance; it’s on avoiding a power-unit ecosystem where the car becomes a masterclass in energy elétrica juggling.
To be clear, the regulation package already includes specific control measures currently in force at the GP de Miami:
- Boost limited to +150 kW.
- Maximum recharge reduced from 9 MJ to 7 MJ for recarga de bateria.
- superclipping generating 350 kW instead of 250 kW.
But the concern remains that Miami is only addressing about 20% of what’s really on the table. So the real fight is for the 2027 “big knob”: the power split.
The deadline that could either unlock or freeze the change
Here’s the brutal reality: the engineering clock is running. A team boss, speaking anonymously to Autosport, put it bluntly. If a decision is taken within two weeks, there’s time to do the full job. If it slips, the sport may have to settle for smaller tweaks instead of a full 2027 configuration.
The internal notion being discussed points to mid-May as the practical cutoff. And that cutoff isn’t arbitrary. A power split change affects:
- Fuel characteristics and consumption planning.
- Tank size and car dimensions.
- Software control strategies and calibration workflows.
- Hardware packaging and integration of the unidades de potência.
More combustion dominance implies more fuel burn. The estimate is that consumption would rise, which then forces a bigger tank. That’s not just a weight story—it’s a design story. So how do you compensate? The thinking is that roughly three fewer race laps could offset the fuel hit. That’s a fascinating compromise, because it shows F1 isn’t ignoring the numbers, even if it’s trying to keep the racing feel intact.
But the real bottleneck is governance. A change of this magnitude would require supermaioria: at least four of the five current manufacturers must approve. That’s the kind of voting threshold that turns strategy meetings into chess matches with deadlines.
Who supports it, and who resists the 2027 revision
No official positions have been released yet, so we’re operating on credible paddock reporting. Still, the pattern matters. The belief is that:
- Mercedes is reportedly against the alteration.
- Honda and Red Bull are believed to be in favour.
- Audi and Ferrari have not yet locked their stance.
And that’s where the tactical part bites. If the required supermaioria can’t be reached, F1 doesn’t get to “partially implement” the 60/40 idea. It would instead pivot to smaller adjustments: software and hardware updates that can be delivered without redesigning the whole energy architecture.
So the question becomes: are we chasing the cleanest racing feel, or are we protecting the safest engineering timeline? In F1, those two goals don’t always align—and this time the calendar is making sure they won’t.
The technical impact on cars, fuel, and race dynamics
Let’s talk consequences like grown-ups. Moving from the current 50/50 balance toward 60/40 or 55/45 changes how drivers ration energy, how the car behaves under throttle, and how frequently the powertrain forces intervention through superclipping and other energy management modes.
More motor a combustion power—estimated to climb from 530 cv to around 600 cv—would likely reduce the need to lean on aggressive energy tactics. That’s the whole pitch: fewer “weird” moments, less reliance on lift-and-coast dominance, and less dependence on contrived behaviours that can distort racing lines and timing.
But the trade is fuel. More combustion means higher consumption, which then drives tank size changes and packaging constraints. If F1 truly believes that about three fewer laps could balance the fuel math, then we’re looking at a regulation that tries to preserve race spectacle while accepting that the physics won’t bend just because the paddock wants it.
And remember: the rules are already strict on key parameters at the GP de Miami level. Boost sits at +150 kW, recarga de bateria is capped at 7 MJ, and superclipping is at 350 kW. The 2027 debate is therefore less about inventing new limits and more about choosing a different allocation of where the performance comes from.
In plain terms: it’s a fight over what the car is built to do when the driver is not “managing,” but actually racing.
What happens if there’s no agreement
If the 60/40 or 55/45 direction can’t clear the supermaioria hurdle in time, the sport won’t freeze the entire project. It will pivot. The likely outcome is a package of smaller changes—software maps, calibration refinements, and selective hardware adjustments—designed to tweak energy behaviour without forcing a full redesign of tank and architecture.
That’s the safety-first route. It keeps the teams inside the engineering window, but it also risks leaving the core complaint unresolved: that the new 2027-era power-unit feel still leans too heavily on energy management behaviours instead of straightforward driving.
So yes, the “no agreement” scenario is technically feasible. But strategically, it’s a half-measure. And half-measures are how you end up with another cycle of dissatisfaction—just with different numbers on the rulebook.
O Veredito Jogo Hoje
We’ll say it plainly: the 60/40 push isn’t a luxury tweak. It’s F1 trying to stop turning racing into a spreadsheet of energy elétrica management, where drivers spend half the race babysitting power modes instead of attacking. If the sport can’t get the supermaioria it needs by mid-May, we’re likely staring at a 2027 that still feels over-coached by the regulations. And that’s not “innovation” anymore—it’s just friction, dressed up as control. A sport built on competition shouldn’t be scared of combustion taking a bigger share of the spotlight.
Perguntas Frequentes
What does F1 want to change in the 2027 engine rules?
The main idea under discussion is adjusting the power distribution inside the unidades de potência, potentially moving from the current 50/50 balance to something like 60/40 or 55/45 between motor a combustão and energia elétrica, while keeping constraints such as boost, recarga de bateria, and superclipping under control.
Why does the decision need to come out by May?
Because implementing a change of this magnitude requires quick approval and enough time to adapt fuel, tank size, car architecture, and the related software and hardware for the new units of power. The guidance being cited is that a decision within about two weeks could still allow full implementation, with mid-May as the practical limit.
What happens if the 60/40 proposal isn’t approved?
If the required supermaioria can’t be reached in time, F1 would likely proceed with less significant adjustments, mainly through software and hardware revisions rather than a full redesign of the power split for 2027.
