Even during Formula 1’s winter break, tensions are rising behind the scenes. Ferrari has reportedly filed formal complaints with the FIA, accusing Red Bull and Mercedes of discovering a way to enhance their engine performance beyond the legal limit. With the 2026 season approaching, this engine controversy is threatening to overshadow the start of the World Championship.

At the heart of the dispute are the new technical regulations, which introduced a lower maximum compression ratio for F1 engines, reducing it from 18.0 to 16.0. This was intended to reduce performance and ensure a more level playing field. However, loopholes in the rules have apparently allowed some teams to exploit a grey area in the regulations.

The compression ratio controversy

At the heart of the issue is how the FIA measures the engines’ compression ratio. Measurements are taken while the engines are cold, as stipulated by the current rules. According to sources, Red Bull and Mercedes have found a way to increase their compression ratio once the engines reach operating temperature. This means that, while the engines comply with the regulations during official checks, they exceed the permitted limits on the track. This gives the teams a potential performance advantage without technically breaking the rules.

This subtle manipulation could result in significant gains during races. It is estimated that this could provide an advantage of up to four-tenths of a second per lap — a margin that can be decisive in Formula 1, especially given how closely matched the top cars are. The fact that this tactic sits in a regulatory grey zone is causing friction among the teams, with Ferrari being particularly vocal in its criticism.

Ferrari’s Strong Response

According to Italian media reports, Ferrari has already lodged multiple complaints with the FIA, urging the governing body to address the perceived loophole. In Maranello, the team is reportedly considering taking formal action if the issue persists after the first race in Melbourne.

The Scuderia is concerned not only with technical fairness, but also with timing. It could take several races — potentially six or seven — to restore a level playing field, by which time the championship battle could be seriously compromised. Without intervention, Ferrari fears that its title hopes for the 2026 season could be damaged before it has had a fair chance to compete.

Championship implications

This dispute highlights a broader challenge in Formula 1: the constant push and pull between innovation and regulation. Teams are constantly looking for ways to exploit small margins, and the FIA must police these innovations while maintaining the competitiveness of the sport. For Ferrari, the immediate concern is obvious: if Red Bull and Mercedes continue to extract more power from their engines under the current rules, the Scuderia could find itself at a disadvantage both on the track and in the championship standings at the start of the season.

As teams prepare for pre-season testing, all eyes will be on the FIA to see if any clarifications or amendments are made. Until then, it may be quiet in terms of racing over the winter, but the engine debate is already heating up, setting the stage for a potentially contentious start to the Formula 1 season.

Ferrari are looking to bounce back strongly in 2026 after a hugely disappointing season saw them winless for the first time in four years. Formula one winless seasons in Maranello are less rare than many may think, with the Scuderia recording their 17th in 75 years.

The longest spell the Italian racing marque went without a win was from 1991-1994 and spanned 58 Grand Prix. The drought was finally ended by driver Gerhard Berger who won his home race in Hockenheim at the 1994 German Grand Prix.

2025 saw the fanfare arrival of Lewis Hamilton’s in January who was afforded a personalised tour of the facilities by group chairman John Elkann. And it was he who was credited in the Italian media with landing the seven tines F1 champion to restore Ferrari’s fortunes.

 

Ferrari suffering longest F1 championship drought

Yet it was not to be and the Scuderia have now extended their drought of constructor championship years to seventeen years, one longer than their previous worst era between 1983-1999. In terms of a drivers’ title, its now eighteen years since Kimi Raikkonen pipped both Fernando Alonso and Lewis Hamilton to the post by a single point. The team’s longest winless streak for this championship is 21 years from 1979 (Jodie Scheckter) to 2000 (Michael Schumacher).

With Formula One’s biggest shakeup of the technical regulations in its history, expectations are high in Maranello for a Ferrari reset. With both new power units and chassis slated for 2026, a change in the pecking order is…READ MORE ON THIS STORY
