Fernando Alonso’s criticism of hybrid power sparks fresh Formula 1 debate
Since the start of the season, Fernando Alonso has made little effort to hide his concerns about Formula 1’s future engine regulations. Even during pre-season testing in Bahrain, the Aston Martin driver expressed doubts about a formula that places such a strong emphasis on energy recovery, arguing that it risks reducing the importance of one of the sport’s purest challenges: carrying speed through the corners and allowing drivers to make the difference.
Alonso reiterated that position ahead of the Canadian Grand Prix, at a time when Formula 1 is actively discussing possible adjustments to the 2027 regulations. One of the proposals currently on the table would move away from the planned 50/50 split between internal combustion and electric power in favour of a more traditional 60/40 balance.
However, that outcome remains far from certain. Manufacturers are still divided on the issue, and there is already speculation that any significant changes could be postponed until 2028.
For Fernando Alonso, though, the discussion goes much deeper than a simple adjustment to the power split. The two-time world champion believes that even if a change is introduced in 2027, it would not fundamentally alter the direction Formula 1 has taken. In his view, the next few seasons would still feel like a transition period before the arrival of a new technical cycle expected around 2031.
More importantly, Alonso repeated a belief he has held for years: that the hybrid era has effectively taken away a decade of what he considers to be genuine Formula 1 racing.
“The world moved toward electrification because it was considered the future. But that doesn’t apply to racing. Racing is something different. Now we’re moving back a little, toward a 60-40 split, and in the future even less. Unfortunately, we have gone through this period since 2014, with the turbo era, and now even more so, where we have lost almost a decade, or even more, of real racing,” Alonso said.
Did hybrid power units really cost Formula 1 a decade of racing?
Alonso’s comments are certainly provocative, but they touch on a debate that has existed since Formula 1 introduced hybrid power units in 2014.
There is little doubt that the early years of the hybrid era were far from perfect. The first generation of power units introduced an unprecedented level of complexity, and reliability immediately became one of the biggest concerns for teams and drivers. The technology was new, sophisticated and extremely difficult to manage, making early growing pains almost inevitable.
Yet over time, those same power units evolved into remarkably reliable and efficient machines. They helped produce some of the fastest Formula 1 cars in history and enabled manufacturers to achieve extraordinary levels of technological development.
Formula 1 has never been a sport that stands still, particularly when technological innovation can provide valuable lessons for the automotive industry. However, Alonso’s criticism is focused less on technological progress itself and more on the impact that electric power has had on the racing product.
The weight problem and changing driving dynamics
One of the most common criticisms raised by drivers concerns the increasing weight of modern Formula 1 cars.
Although enhanced safety standards have contributed significantly to the growth in vehicle mass, the addition of electric motors and large battery systems has also played a major role. The result is a generation of cars that are considerably heavier than their predecessors.
For drivers, that extra weight inevitably affects agility and responsiveness. It is one of the reasons why many competitors have spent years calling for lighter cars that better reflect the nimble machines that defined previous eras of Formula 1.
Those who raced during the V10 and V8 eras naturally look back on those cars with a degree of nostalgia. Their lighter weight, sharp reactions and simpler energy management created a very different driving experience from what modern Formula 1 drivers encounter today. Yet the issue extends beyond weight alone.
When electric power becomes a dependency
Another key concern is how electric power is integrated into the overall performance package.
When electric assistance functions as a supplementary system, similar to the original KERS concept, its influence on the racing spectacle is relatively limited. However, when the electric component becomes a fundamental part of overall performance, new challenges inevitably emerge.
One of those challenges is derating, the reduction in available power that can occur toward the end of long straights when battery energy becomes depleted.
Under the previous generation of hybrid regulations, this effect was generally less pronounced. The MGU-K produced less power than under the future regulations, making energy deployment easier to manage. Teams also benefited from the often-overlooked contribution of the MGU-H, which helped improve energy efficiency and recovery.
Even then, energy management remained a critical element of performance. Drivers sometimes began qualifying laps with batteries charged to around 90% rather than fully topped up, while race engineers carefully planned deployment strategies to maximise the additional 160 horsepower delivered by the MGU-K during overtaking opportunities.
It was a very different style of Formula 1, but one that generally remained manageable within the limitations of the technology.
McLaren driver Oscar Piastri recently explained how these challenges have existed for years, even under previous regulations.
“Even with the previous engines, which had an 80-20 or 85-15 split, on some circuits we didn’t have full deployment everywhere. We came very close, and on many tracks we achieved it, but until you find a balance that allows you to maintain full electric power throughout every section, for us drivers the straights will always feel a little strange,” Piastri explained.
“Regardless of the power split, you will always face these difficulties in starting a qualifying lap and getting the battery into the correct operating window. It’s an extremely delicate balance and very difficult to manage because either you start the lap without a fully charged battery, or you start it without turbo boost pressure. At that point, there isn’t really a solution other than changing the hardware.”
The challenge facing the 2026 regulations
The real issue emerges when teams are forced into compromises and when hybrid technology stops being an enhancement and becomes something on which performance entirely depends.
That challenge has become even more visible under the current regulatory philosophy. Formula 1 plans to significantly increase the importance of electric power while simultaneously removing the MGU-H and retaining battery capacity limitations. Many engineers believe that combination exposes some of the fundamental weaknesses of the concept.
Those limitations can translate into significant speed losses on certain circuits or force drivers to carefully manage throttle application, particularly during qualifying sessions. Although recent adjustments introduced in Miami have helped reduce some of the most extreme driving techniques, the underlying challenge remains.
Interestingly, some of these issues are less apparent in Formula E. Despite being fully electric, that category was designed from the outset around the strengths and limitations of electric propulsion, rather than attempting to combine it with a traditional internal combustion engine.
Finding the right balance is therefore far more complicated in a hybrid formula, especially one built around compromises between performance, sustainability and technological relevance.
It is no coincidence that Formula 1 is now discussing a possible move toward a 60/40 power split for 2027 or 2028.
Not all drivers share Alonso’s view
While Alonso remains one of the strongest critics of the current direction, not every driver sees the situation in the same way.
Carlos Sainz has expressed a more moderate position, suggesting that the 2025 power units represented a stronger balance between combustion and electrical power. Rather than rejecting hybrid technology entirely, Sainz believes it works best when it serves as an enhancement rather than the foundation of performance.
“I think for us drivers it will never be enough because we all love the same thing: if there is an electric component, it should be an added value, not something you depend on as happens today. In the past we had KERS, we had the previous power unit regulations, where the electric side really felt like an addition on top of an already strong power unit,” Carlos Sainz explained.
“And I think that for the drivers, for the purists, and even for you journalists, we will all continue to believe that even a 60-40 split probably isn’t enough. But at least it is something that allows real racing while we wait for true racing and true engines to return in 2030.”
Whether one agrees with Fernando Alonso or not, his comments have reignited an important discussion about the future identity of Formula 1. The debate is not necessarily about whether hybrid technology belongs in motorsport, but rather about how it should be used. The challenge for Formula 1 is finding the balance between technological innovation and preserving the racing spectacle that has always defined the sport.
