The technical revolution in Formula 1 scheduled for 2026 will not concern aerodynamics alone. The true heart of the change will be the power unit, which is set to completely redefine the way single-seaters are conceived and how races are managed from both a technical and strategic perspective. With just over a month to go before the first private tests in Barcelona, scheduled from 26 to 30 January, a strong sense of uncertainty still dominates the paddock. No team has concrete certainty about its real competitive level, and the overall picture remains fluid for everyone involved. This is the current situation at Ferrari regarding the engine project for the 2026 season.
Paolo Filisetti of RacingNews365 had the opportunity to speak directly with Enrico Gualtieri, technical director of power units at Scuderia Ferrari, in order to better understand the most complex challenges that lie ahead. The discussion comes at a time when anticipation is growing for the first official car launches, with Ferrari set to unveil its new single-seater on 23 January before heading to Catalonia for the initial on-track running.
What will the Ferrari engine look like in 2026?
The 2026 power units will be profoundly different from those used up to the end of the 2025 season. The most visible and impactful change concerns the distribution of maximum power, which will be evenly split between the internal combustion engine and the electric component, with roughly 500 horsepower coming from each side. In concrete terms, the electrical part will reach 350 kW, almost three times the current 120 kW, marking a shift from the familiar 80/20 balance to an unprecedented 50/50 split.
The second crucial turning point involves energy recovery. From 2026 onwards, the MGU-H, the motor generator unit connected to the turbocharger, will be eliminated entirely. All energy recovery will be handled exclusively by the MGU-K during braking phases and lift-off situations. According to Enrico Gualtieri, this decision has forced manufacturers to adopt a completely new development philosophy when designing the next generation of power units.
The substantial increase in electric power output brings with it direct and significant consequences. The battery will no longer be capable of sustaining full electrical deployment for an entire lap, especially on circuits characterised by long straights, where energy reserves could be depleted sooner than expected. At the same time, recharging becomes more complex, because without the MGU-H, everything depends on braking efficiency and highly refined energy management strategies.
Despite this scenario, Enrico Gualtieri does not foresee races being dominated by extreme lift-and-coast driving techniques. The real difference, he explains, will be made by software. Energy management systems, power distribution logic and recovery strategies will be decisive and could represent an enormous competitive advantage for those who manage to find the optimal balance between performance and efficiency.
The driver’s role in 2026 becomes decisive
The new regulations will also place greater responsibility on the drivers themselves. Communications from the pit wall will remain limited, but those behind the wheel will be required to intervene far more frequently using the controls on the steering wheel. Drivers will need to independently adapt energy usage modes based on battery status, track characteristics and the specific phase of the race. This is an element that will make driver sensitivity, technical understanding and adaptability even more central to overall performance.
Active aerodynamics, introduced not to increase outright performance but to compensate for energy limitations, should not by itself create large performance gaps. Its effectiveness will depend heavily on how well it is integrated with electronic control systems and power unit strategies, reinforcing the idea that the 2026 Formula 1 cars will be the result of extremely complex system integration.
Reliability and sustainable fuels: Ferrari’s approach
The engine regulations were finalised more than two and a half years ago with the aim of ensuring stability and avoiding the kind of early dominance seen at the start of the hybrid era in 2014. However, according to paddock sources, reliability issues have emerged for many manufacturers during dyno testing. A significant portion of these difficulties is linked to the introduction of 100 per cent sustainable fuels, not because of their intrinsic quality, but due to the extreme pursuit of combustion efficiency and weight reduction. This challenge is amplified by the fact that the minimum car weight will drop to 768 kilograms.
Enrico Gualtieri neither confirmed nor denied rumours regarding potential slowdowns in Ferrari’s 2026 engine programme, nor did he comment on uncertainties related to the materials used in the cylinder head. What is certain is that all engine manufacturers are facing an exceptionally complex homologation phase, operating in a technical landscape that is entirely new and largely unexplored.
Formula 1 in 2026 will effectively become an open-air laboratory. Once the season begins, the development curve is expected to be extremely rapid and continuous, not only in the pursuit of performance but also in addressing any structural limitations that may emerge within the power units. It is a revolution that could fundamentally reshape the competitive balance of the World Championship and redefine the hierarchy of the sport for years to come.
