Ferrari could bring back its distinctive “Christmas Tree” rear-wing configuration on the SF-26 at the Singapore Grand Prix, with Marina Bay providing exactly the type of maximum-downforce environment for which the solution was developed. The encouraging performance shown in Malaysia confirmed that the car still has significant potential when it operates inside the correct performance window, even before Ferrari introduces its most important aerodynamic package of the year at Austin.
Despite the strategic problems at Sepang, Charles Leclerc and Lewis Hamilton produced a strong recovery, with both SF-26s showing solid pace. Singapore, however, presents a completely different technical challenge, shifting the emphasis towards maximum downforce, low-speed stability and traction.
Maximum downforce in Singapore could bring back Ferrari’s ‘Christmas Tree’
Marina Bay is dominated by slow 90-degree corners and requires some of the highest downforce levels of the season. Performance over a single lap will also be especially important because the 2026 Singapore GP uses the Sprint format, creating two separate qualifying sessions during the weekend.
At Budapest, Ferrari fully exploited the possibilities offered by the updated Macarena architecture. In the central area of the rear wing, the team added a series of vertically arranged flaps positioned in a cascade. Singapore represents an ideal venue to bring that unusual rear configuration back, as originally planned.
The Ferrari concept takes inspiration from an idea used by several rivals in Monaco. On a more conventional solution, the volume in question is largely occupied by the rear wing’s central actuator system. The particular architecture adopted on the SF-26 instead incorporates the actuator into the endplate, leaving otherwise unused space available for additional aerodynamic elements.
That vacant area can therefore be transformed into useful aerodynamic surface. In Hungary, Ferrari filled it with several stacked profiles, creating a genuine cascade of elements through the central section of the wing. McLaren and Mercedes had adopted comparable concepts in Monaco, where they could dispense with the conventional central actuator because the wings would remain in their closed configuration.
The arrangement is one of the more unusual details of the SF-26 and forms part of the broader development of the car covered in the ScuderiaFans Ferrari technical analysis section.
Hanger flaps have become part of the SF-26 rear-wing concept
The role of Ferrari’s hanger flaps has also evolved during the season. These are the small aerodynamic elements positioned along the upper edge of the final flap. Initially, they appeared to be primarily associated with high-downforce configurations, but Ferrari continued using them across circuits with very different aerodynamic requirements and effectively stopped removing them.
The clearest confirmation came at Monza. Even at a circuit where reducing aerodynamic drag is a major priority, the hanger elements remained on the SF-26.
That is a significant indication of their role. Rather than simply being additional devices used to generate downforce, the profiles now appear to have become an integral part of how the complete rear wing operates.
The solution will not remain available indefinitely. From 2027, the FIA will no longer permit these elements, having identified them among the components to be removed as part of the effort to reduce the aerodynamic load generated by the new generation of cars by around 20 per cent.
Why the ‘Christmas Tree’ could also work in Mexico
The “Christmas Tree” configuration could become useful again later in the season in Mexico. The high altitude of Mexico City dramatically reduces air density, encouraging teams to run aerodynamic configurations normally associated with maximum-downforce circuits while still generating relatively limited drag.
That makes the unusual Ferrari rear-wing architecture potentially suitable for more than just Marina Bay, despite the very different characteristics of the two venues, accordign to Rosario Giuliana for autoracer.
What to expect from the Ferrari SF-26 in Singapore
Singapore is more rear-limited than Malaysia and features lower average speeds, repeated acceleration phases and a particular need for stability through slow-corner sequences. Those characteristics inevitably move the set-up compromise towards a car that is agile and responsive while maintaining control at the rear.
Ferrari still has a limitation in the operating window of the rear of the SF-26, with wheelspin not yet completely under control. Marina Bay could nevertheless provide a more favourable environment for the car. The demands of the circuit and the balance between traction and agility are explored further in the Marina Bay circuit analysis.
The track could also suit Ferrari from the drivers’ perspective. Singapore has historically been a circuit Lewis Hamilton enjoys, while Charles Leclerc has often been particularly effective on this type of street circuit when extracting performance over a single lap.
Compared with Sepang, Marina Bay offers characteristics that should better match Charles Leclerc’s preferred feeling from the car and, more generally, the type of driving conditions both Ferrari drivers tend to appreciate. Lewis Hamilton also arrives with reasons for encouragement ahead of the weekend, with his Singapore prospects with Ferrari shaped by the different demands of the street circuit.
Ferrari’s major SF-26 upgrade remains scheduled for Austin
Ferrari arrived in Malaysia with several detail changes to the SF-26, but without what is internally regarded as the car’s true next development step. No significant upgrades are expected in Singapore, which marks the final event of a demanding triple-header.
The major technical step remains Austin, where Ferrari has scheduled its most substantial aerodynamic package of the year. Until then, Singapore will be primarily about extracting more from the existing SF-26 package and exploiting a high-downforce rear-wing configuration designed specifically for circuits with these characteristics.
