Ferrari’s big questions: engine performance, Lewis Hamilton criticism and Formula 1’s uncertain future. Ferrari faces growing questions over its SF-26 engine concept.

Ferrari under scrutiny: engine, Lewis Hamilton and the doubts surrounding F1 2027

The 150th episode of Race Tech tackled some of the most debated technical topics currently dominating the Formula 1 paddock. Together with engineer Riccardo Romanelli, the discussion focused on Ferrari engine speculation, the possible consequences of the Scuderia’s design philosophy for the SF-26, reported concerns from Lewis Hamilton, and the increasingly serious questions surrounding the proposed 2027 Formula 1 regulations.

Ferrari engine debate: compromise between power and aerodynamics?

One of the key talking points was the growing speculation surrounding Ferrari’s power unit concept. According to recent technical theories, Ferrari may have prioritised higher operating temperatures and an especially compact packaging philosophy in order to benefit the car’s aerodynamic performance.

The hypothesis centres primarily on material choices in the cylinder head and the overall thermal management strategy of the power unit. According to some interpretations, this approach could have created benefits in weight distribution and external cooling layout, but potentially at the cost of peak engine performance compared to Ferrari’s direct rivals.

Riccardo Romanelli approached that theory with caution, pointing out that engine manufacturers normally pursue maximum thermal efficiency, rather than deliberately sacrificing performance for aerodynamic reasons.

Ferrari’s FTM system and exhaust flow management

Another major topic was Ferrari’s FTM system, which has attracted growing technical attention in recent weeks.

The discussion focused on Ferrari’s apparent use of exhaust gases to generate an upwash effect at the rear of the car. According to Riccardo Romanelli, the concept may be less about generating direct downforce and more about reshaping airflow behaviour in the region between the diffuser and rear wing.

This would represent a refined aerodynamic solution capable of improving overall efficiency without relying on especially aggressive vortex generation.

At the same time, Riccardo Romanelli pushed back against the theory that hotter exhaust temperatures automatically produce greater aerodynamic load. From a physics standpoint, hotter gas has lower density, meaning the relationship is far more complex than some simplified interpretations suggest.

Ferrari’s compact turbo: smart packaging or performance limitation?

Another intriguing area of discussion involved Ferrari’s reported decision to adopt a smaller turbocharger than some of its closest rivals.

That choice may have helped Ferrari create a more compact rear-end packaging concept, giving aerodynamic designers greater freedom around bodywork and airflow management. However, the same decision could also have limited the ultimate performance ceiling of the power unit, particularly in an era where hybrid and engine efficiency remain critical performance differentiators.

The debate remains open, especially given how tightly integrated modern Formula 1 car concepts have become.

Lewis Hamilton’s reported concerns about Ferrari’s direction

Significant attention was also given to reports involving Lewis Hamilton and his apparent concerns about Ferrari’s technical direction.

According to the discussion, the seven-time world champion may have questioned aspects of Ferrari’s aerodynamic development philosophy, particularly regarding front wing airflow management.

Compared to Red Bull, Ferrari appears to be following a different aerodynamic philosophy around the front wheels. While Red Bull tends to favour a more aggressive outwash-focused concept, Ferrari may be pursuing a setup with a stronger inwash component. Riccardo Romanelli explained that these are not isolated technical details, but design choices that influence the behaviour of the entire car, from the floor to the rear diffuser.

Formula 1 2027 regulations: growing concerns

The final part of the discussion shifted toward the proposed 2027 Formula 1 regulations, where increasing concerns are beginning to emerge despite earlier reassurances from Liberty Media and Stefano Domenicali.

One of the biggest issues relates to electric energy deployment and the large speed differentials predicted in certain phases of a lap. According to Riccardo Romanelli, seeing cars with speed differences exceeding 60 km/h in specific situations would raise not only technical concerns, but genuine safety questions.

As a result, the FIA is reportedly already considering significant adjustments, including increasing the importance of the internal combustion engine relative to the electric component.

Final analysis

Ferrari’s technical situation remains one of the most heavily discussed subjects in Formula 1. Questions surrounding engine philosophy, aerodynamic compromises, and overall design direction continue to generate debate inside and outside the paddock.

At the same time, uncertainty over the 2027 regulations highlights how Formula 1 is entering another delicate transition period, where technical balance, entertainment, and safety will need to be carefully aligned.
