Even before the ink has dried on F1’s landmark 2026 technical regulations, the conversation around what comes next is already well underway. Carlos Sainz, speaking in his role as GPDA president, is making clear that drivers want the sport’s governing bodies to take a firm stand on proposed 2027 power unit changes, specifically a shift toward a 60-40 combustion-to-electrical power split that would mark another significant departure from the current regulatory direction.
A New Formula Already Under Review
Formula 1’s 2026 power unit regulations were designed to be transformative. The new framework placed a far greater emphasis on electrical deployment than anything seen before in the sport, moving toward a near 50-50 split between internal combustion and electrical power. It was a bold statement of intent, aligning the sport with sustainability goals while attempting to attract new manufacturers and satisfy existing ones.
Almost immediately, however, questions emerged. Concerns around driveability, overtaking potential, and competitive balance began circulating among teams and drivers, prompting serious discussions about whether adjustments were needed before the regulations had even produced a single race lap. Those discussions have now evolved into concrete proposals for 2027, with a revised power unit split at the center of the debate.
The 60-40 Split and What It Means
The proposed 2027 adjustment would tilt the power unit balance toward internal combustion, with approximately 60 percent of total power coming from the combustion engine and 40 percent from electrical deployment. This represents a meaningful rollback from the ambitions of the 2026 framework and reflects genuine anxiety within the paddock about how the more electrical-heavy formula will translate on track.
From a technical standpoint, the shift matters for several reasons. A higher combustion component generally provides more consistent and predictable power delivery across a wider range of circuits and conditions. Electrical deployment, while powerful, is heavily dependent on energy management strategies, battery charge levels, and deployment windows, all of which can create unpredictable performance swings. Drivers have long flagged concerns about the drivability implications of leaning too heavily on electrical power, particularly in slow-speed corners and during overtaking sequences where instant and sustained throttle response is critical.
Stakeholders are currently in the midst of negotiations over these tweaks, and the outcome will shape not only the technical landscape of 2027 but also the broader direction of F1’s hybrid power story for the years beyond.
Sainz Steps Up as GPDA Voice
Carlos Sainz has wasted no time in establishing himself as a serious force in the driver advocacy space since taking on the GPDA presidency. His call for F1 and the FIA to be tough in pushing these changes through is not just a personal opinion but a collective message from the driver community, one that carries real weight in the regulatory process.
Sainz’s position is straightforward. Strong governance is needed to ensure the proposed changes are not diluted or delayed by competing commercial interests or manufacturer lobbying. The concern among drivers appears to be that without firm leadership from the FIA and Formula 1’s commercial rights holder, the negotiations could produce a watered-down compromise that fails to address the core issues around racing quality.
This kind of driver-led advocacy has become increasingly relevant in the modern F1 era. The GPDA has grown into a genuine stakeholder voice, and with a high-profile figure like Sainz at its helm, the organization has both the credibility and the platform to influence outcomes that might otherwise be decided entirely behind closed doors.
Why the Timing Matters
The urgency behind Sainz’s message is tied directly to the regulatory calendar. With 2026 approaching and teams already deep into their power unit development programs, any confirmed changes for 2027 need to be locked in with enough lead time to allow manufacturers to plan accordingly. Delays or indecision at this stage could create a situation where teams are building 2026 hardware with incomplete knowledge of what the following year’s rules will demand.
There is also a broader symbolic dimension to this moment. F1 is entering one of its most technically complex regulatory eras in decades, and the early signs of hesitation around the 2026 power unit philosophy raise legitimate questions about long-term planning and regulatory stability. If the sport is seen as willing to revise major technical frameworks before they have even been raced, it risks undermining confidence among manufacturers who have committed substantial investment to the current roadmap.
At the same time, getting the regulations right matters far more than getting them locked in quickly. The history of F1 is littered with examples of rules that produced unintended consequences on track, from processional racing to unmanageable cost escalation. Sainz and the GPDA are essentially arguing that this is one of those moments where the sport must be willing to make a difficult call in the interest of the long game.
Looking Ahead
The debate around the 2027 power unit split is about much more than percentages on a technical specification sheet. It is a test of how Formula 1 and the FIA manage the competing pressures of manufacturer interests, sustainability commitments, and the fundamental need to produce compelling racing. Carlos Sainz’s intervention, backed by the GPDA, sends a clear signal that drivers are not passive observers in this process. With negotiations still ongoing and the 2026 season drawing closer on the horizon, the coming months will determine whether the sport’s leadership has the resolve to deliver a regulatory framework that serves racing first. If Sainz and the driver community have their way, the answer will be yes.
