Singapore GP – Technical analysis and first images from the circuit: ultra high downforce wings
After the stop on the shores of the Caspian Sea, Formula 1 heads south, just 140 kilometers from the equator, to embrace the spectacular night setting of the Marina Bay Street Circuit. The change here is not only about the scenery, but also about the extreme conditions: humidity often climbs beyond 70%, while temperatures remain steadily between 24 and 31 °C. This combination makes the Singapore Grand Prix one of the most demanding races on the calendar. Drivers face a true physical challenge, with some losing as much as three kilograms of body weight during the race due to dehydration and heat stress.
From a strategic perspective, memories quickly turn back to last year’s edition. On that occasion, 14 drivers opted to start on the medium C4 compound, a choice that provided greater flexibility for managing the single pit stop. Some even managed to stretch the stint to more than 45 laps on the same set of tires. Once again this year, tire management will play a central role, particularly when it comes to controlling temperatures and navigating the constant traffic around the tight streets of Marina Bay. Overtaking is notoriously difficult here, and when sudden downpours hit the circuit — as often happens — the track becomes “green” with low grip, accelerating tire wear and adding to the unpredictability.
The layout of the Singapore track measures 4.940 km and features 19 corners. It is a true urban challenge: very few opportunities to relax, constant acceleration zones, and a surface with limited grip, typical of street circuits. Painted road markings, which become slippery in the wet, add another layer of danger. Even with four DRS zones, the fundamental character of the circuit does not change — overtaking remains rare and every small mistake can easily end with a car meeting the walls. A new element for 2025 is the increase of the pit lane speed limit to 80 km/h, a detail that could create fresh strategic options, especially in a race where safety cars are a frequent occurrence.
Singapore also represents one of the toughest stops of the year for braking systems. Brembo engineers classify Marina Bay with a severity index of 4 out of 5. The most demanding braking point is at Turn 7, known as “Memorial,” where cars decelerate from 308 km/h to 128 km/h in just 1.9 seconds — an enormous load on both car and driver.
Between high humidity, thermal tire degradation, the constant threat of rain, and the heavy stress placed on brakes and drivers, Singapore is a race that leaves no room for rest. In such conditions, choosing the right car setup becomes crucial. Teams are expected to favor configurations optimized for qualifying performance, even if that means sacrificing some tire longevity during the race.
The first insights have arrived thanks to Albert Fabrega, always punctual with his updates, who has once again published a comparison of the different rear wing specifications brought by the teams.
According to Albert Fabrega’s early analysis, the upper mobile flaps of all cars are quite similar, designed with a high angle to maximize downforce when the DRS is closed. However, the main rear wing profiles show significant differences between teams. McLaren and Red Bull’s solutions are almost identical, offering slightly more downforce than Ferrari’s setup, but less than Mercedes. As is often the case, Alpine has opted for the lightest rear wing configuration of the field. Stake, meanwhile, has chosen a particularly unusual design, featuring a heavily scooped central section that stands out among the grid.
