Ferrari F1 engine concerns grow after Miami GP as rumours point to major power deficit. Ferrari face growing concerns after the Miami Grand Prix.

Fresh concerns have emerged within the Formula 1 paddock suggesting that Ferrari may be facing a significant internal combustion engine shortfall following a disappointing Miami Grand Prix weekend, where both performance and software-related expectations failed to materialise as planned.

The Italian team arrived in Florida with a highly anticipated power unit software update aimed at improving energy management and overall straight-line performance. However, early indications from race data and on-track execution suggest that the upgrade did not deliver the expected gains, raising questions about Ferrari’s current competitive position in the 2026 Formula 1 season.

Charles Leclerc’s Race Collapses Late as Lewis Hamilton Inherits Positions in Chaotic Ferrari Weekend

Charles Leclerc initially showed strong pace by briefly leading the Miami Grand Prix at the start, but the Ferrari driver gradually slipped backwards as Kimi Antonelli and Lando Norris moved ahead before the first pit stop phase. The situation worsened when Charles Leclerc dropped out of podium contention after being overtaken by Oscar Piastri during the middle stages of the race.

In the closing moments, Charles Leclerc’s race completely unraveled after he spun and made contact with the barrier, forcing him to limp back to the finish while under severe damage limitations. Further chaos unfolded when George Russell and Max Verstappen overtook him at the final corner. Post-race stewards then imposed a 20-second penalty on Charles Leclerc for repeatedly leaving the track without sufficient justification, which ultimately dropped him to eighth position in the final classification.

This sequence of events indirectly promoted Lewis Hamilton to sixth place. The Briton’s race had already been compromised early on after contact with Franco Colapinto resulted in sustained car damage, leaving him isolated between the midfield pack and the front-running group for most of the Grand Prix.

Concerns Grow Over Ferrari’s Straight-Line Performance and Engine Output

Despite both Charles Leclerc and Lewis Hamilton failing to maximise their individual races, the broader concern in the paddock centres on Ferrari’s underlying performance deficit rather than isolated incidents.

Even in a trouble-free scenario, it is widely believed that Ferrari would still have struggled to match the pace of their direct rivals, with data analysis highlighting a notable gap in outright performance. Reports from Motorsport IT indicated that Charles Leclerc’s fastest lap during the race was approximately six-tenths of a second slower than race winner Kimi Antonelli, underlining a clear pace disadvantage.

Unconfirmed rumours within the Formula 1 paddock have suggested that Ferrari may be lacking as much as 30 horsepower compared to Mercedes when comparing internal combustion engine output. While these figures remain speculative, they align with observed struggles on Miami’s long straights, where Ferrari appeared unable to consistently match top-end speed.

Adding further concern, Lewis Hamilton repeatedly communicated issues regarding insufficient power delivery throughout the race, suggesting that the updated energy management software introduced specifically for the Miami Grand Prix may not have functioned as intended from an engineering standpoint.

Ferrari are expected to eventually benefit from the ADUO development convergence system, designed to assist engine manufacturers who are trailing their competitors. However, this regulatory advantage is not expected to take effect until the middle portion of the summer calendar, meaning immediate relief is unlikely.

Canada Expected to Expose Ferrari’s Weaknesses Before Potential Monaco Respite

While Ferrari’s limitations were already evident in Miami, the upcoming sequence of races could prove even more challenging for Charles Leclerc and Lewis Hamilton. Earlier events in Bahrain and Saudi Arabia were not held this season, but both circuits are traditionally among the most power-sensitive on the calendar and would likely have highlighted similar deficiencies.

Although Miami is not considered a pure power circuit, Ferrari’s apparent straight-line deficit was still visible, particularly across the longer acceleration zones. This raises concerns ahead of the Canadian Grand Prix, which is widely regarded as the first true high-power-demand circuit of the season.

On paper, Ferrari may enter the Canadian Grand Prix as only the fourth-strongest team, especially given the strong performance levels shown by rivals powered by Red Bull-linked engine performance. This projection leaves little optimism for a breakthrough result in Montreal.

In contrast, the Monaco Grand Prix two weeks later may offer Ferrari a more favourable opportunity due to its low-speed, high-downforce characteristics, potentially allowing Charles Leclerc and Lewis Hamilton to compete more competitively. However, unless broader improvements are made across both power unit efficiency and overall aerodynamic balance, Ferrari’s package currently appears insufficient to consistently challenge Mercedes, while McLaren have now clearly established themselves as the closest challengers to the front of the field.
