Ferrari prepares radical engine rethink as Mercedes power gap comes under attack
Ferrari’s resurgence during the 2026 Formula 1 season has changed the perception of the Maranello team throughout the paddock. After a disappointing 2025 campaign, the Scuderia has returned to the front of the grid with a much stronger package, highlighted by Lewis Hamilton’s breakthrough victory at the Spanish Grand Prix. Yet despite the progress made with the SF-26, Ferrari remains fully aware that one crucial weakness still separates it from the benchmark established by Mercedes.
While the Ferrari SF-26 has earned praise for its aerodynamic efficiency, cornering speed and overall balance, there is a widespread belief that the Italian team continues to trail Mercedes when it comes to outright power unit performance. That reality has pushed Ferrari engineers to explore increasingly aggressive solutions as they attempt to close the gap and strengthen their championship ambitions.
According to recent reports, Ferrari is now evaluating a significant change to one of the most distinctive technical features of its 2026 power unit. The team is reportedly considering abandoning the smaller turbocharger concept that has been a defining characteristic of the SF-26 since the beginning of the season.
The objective is clear. Ferrari wants to reduce the remaining horsepower deficit to Mercedes and maximize the opportunities provided by the FIA’s ADUO development framework. If successful, the move could become one of the most important technical decisions of the entire season.
Mercedes still leads the power unit race
Since the introduction of Formula 1’s new 2026 regulations, Mercedes has generally been regarded as the manufacturer that produced the strongest power unit package. The Brackley-based team quickly established itself as a reference point, converting that advantage into a dominant start to the championship.
Mercedes secured six victories in the opening seven races, demonstrating the effectiveness of its overall package. Although Ferrari has dramatically improved its competitiveness compared to last year, the Scuderia recognizes that matching Mercedes consistently requires further gains from the power unit department.
This is where the FIA’s ADUO mechanism becomes particularly important. The system was introduced to help manufacturers recover performance deficits by granting additional development opportunities to those who fall behind certain performance targets.
Ferrari is expected to benefit from this framework, giving engineers in Maranello the chance to introduce meaningful upgrades throughout the season. Those additional development windows could prove crucial in the battle to reduce Mercedes’ advantage.
For Lewis Hamilton and Charles Leclerc, any improvement in straight-line speed could have an enormous impact. Both drivers already have a car capable of competing at the front, and additional engine performance would make Ferrari an even stronger contender for victories and championship points.
Austria marks the beginning of Ferrari’s recovery plan
Ferrari is not wasting time before introducing its first major engine evolution. The team is expected to debut an upgraded power unit at the Austrian Grand Prix, where engineers hope to improve both performance and operational efficiency.
The Red Bull Ring represents an important test because of its layout. With several long acceleration zones and significant power sensitivity, Austria should provide a clear indication of whether Ferrari’s development efforts are producing the desired results.
However, the Austrian upgrade appears to be only the first phase of a much broader strategy. Reports indicate that Ferrari is already planning a second major power unit evolution, potentially targeted for either the Dutch Grand Prix at Zandvoort or the Italian Grand Prix at Monza. Both events take place shortly after the summer break and could become key milestones in Ferrari’s attempt to reach engine parity with Mercedes.
Monza, in particular, carries enormous symbolic importance. As Ferrari’s home race, it would represent the perfect stage to demonstrate that the Scuderia has significantly reduced the gap to its German rival.
The smaller turbocharger concept under review
The most intriguing aspect of Ferrari’s development strategy concerns its turbocharger philosophy.
At the beginning of the 2026 season, Ferrari chose a smaller turbocharger than several of its rivals. The decision was widely regarded as an innovative response to Formula 1’s new power unit regulations and the removal of the MGU-H system.
Without the MGU-H, manufacturers faced new challenges in maintaining responsiveness and minimizing turbo lag. Ferrari’s smaller turbocharger helped address those concerns and contributed to the impressive launches and acceleration characteristics displayed by the SF-26 during pre-season testing. Early in the year, the concept appeared highly effective. Ferrari frequently looked sharper off the line than several rivals, and many observers considered the design one of the cleverest engineering solutions introduced under the new regulations.
However, Formula 1 development moves quickly, and advantages rarely remain static. As rival manufacturers refined their own packages, Ferrari’s initial edge gradually diminished. What once appeared to be a significant competitive advantage now seems less decisive than it did at the start of the season.
According to reports, Ferrari’s turbocharger is approximately 10 millimetres smaller than the equivalent design used by Mercedes. Although that difference sounds minor, the impact at Formula 1 level can be substantial.
Current estimates suggest the smaller turbocharger may cost Ferrari as much as seven horsepower compared to the Mercedes solution. While seven horsepower alone is unlikely to determine a championship, it becomes far more significant when combined with other performance deficits across the power unit package.
How much performance can Ferrari recover?
Some estimates suggest Ferrari’s original 2026 power unit started the season approximately 30 horsepower behind Mercedes. In modern Formula 1, a gap of that magnitude can influence qualifying results, overtaking opportunities, race strategy flexibility and overall competitiveness.
The encouraging news for Ferrari is that engineers believe a significant portion of that deficit can be recovered through development.
Internal expectations surrounding the Austrian Grand Prix upgrade are particularly ambitious. Reports suggest Ferrari could claw back around 20 horsepower through its first major engine evolution, dramatically reducing the advantage currently enjoyed by Mercedes. If those projections prove accurate, the championship battle could become far more competitive during the second half of the season.
Combined with what many insiders already regard as one of the strongest chassis and aerodynamic packages on the grid, additional engine performance could transform the SF-26 into a complete all-round contender.
This possibility explains why Ferrari is reportedly reconsidering its original commitment to the smaller turbocharger concept. Earlier in the season, there were indications that the team intended to retain the philosophy throughout the year. Now, however, performance gains appear to have become the overriding priority.
Ferrari’s willingness to revisit one of the key pillars of its power unit design demonstrates just how aggressively the team is pursuing Mercedes.
What it means for Lewis Hamilton and Charles Leclerc
For Lewis Hamilton and Charles Leclerc, Ferrari’s development strategy sends a clear message. The team is prepared to make bold decisions if they increase the chances of competing for victories and championships.
Lewis Hamilton’s success in Barcelona proved that Ferrari already possesses a car capable of winning races against the strongest opposition. Charles Leclerc has also consistently demonstrated strong pace throughout the season, reinforcing confidence in the underlying quality of the SF-26.
If Ferrari succeeds in reducing the power deficit over the coming months, the implications could be enormous. Mercedes will continue developing aggressively, while McLaren and Red Bull remain major threats. Nevertheless, Ferrari appears determined to use every available opportunity to close the gap.
The next phase of the season could therefore prove decisive. Austria should offer the first indication of how effective Ferrari’s recovery plan will be, while Monza could become the event where the Scuderia demonstrates that it has genuinely reached a new level of competitiveness.
Should the planned upgrades deliver the expected gains, Lewis Hamilton and Charles Leclerc may soon find themselves driving a Ferrari capable of matching the Mercedes W17 cars of Kimi Antonelli and George Russell not only in the corners, but also on the straights. And if that happens, the battle for the 2026 Formula 1 World Championship could become more intense than ever.
