The 2026 Formula 1 season rolls on this weekend with Singapore playing host to the final Sprint of the year. But before the machines hit the tarmac, let's look at the beast that is the Marina Bay Street Circuit.
While the now-defunct Thomson Road Grand Prix circuit held eight non-championship editions of the Singapore Grand Prix between 1966 and 1973, the country made its official debut on the F1 calendar in 2008. An original design by Herman Tilke was modified by engineering company KBR Inc, making use of public roads by the city’s harbour to create an exhilarating night race that remains one of the most physically demanding of the season. The bumpy surface of the streets, humid conditions and long lap time come together to form a relentless challenge for the drivers, which Sebastian Vettel mastered with five victories – just one more than Hamilton as it stands. Ferrari and Mercedes share the record for the most wins in Singapore, with five apiece.
Marina Bay was altered ahead of the 2023 race to cut the number of corners down from 23 to 19, but it’s still a twisty, tight circuit that requires stamina and maximum focus for the entirety of the lap. Short run-off areas and close walls mean that the smallest of mistakes are punished – every Singapore Grand Prix featured at least one Safety Car appearance until 2024, when Lando Norris managed to win even after grazing the wall on multiple occasions. Jolyon Palmer, former Renault F1 driver, explained: “Marina Bay is a long, complex circuit, and draining as well – a little bit like Monaco – with plenty of bumps. It’s all about the low-speed and having decent turn-in without losing the rear or suffering snaps of overser.” Palmer added that braking is particularly tricky at Turn 7, where it's easy to run wide, and the newer Singapore Sling through Turns 10 and 11 can lure drivers into going too deep.
New regulations bring fascinating technical changes for the weekend. Straight Mode is a different aerodynamic configuration that allows cars to reduce their drag, making them more efficient when accelerating up towards top speed. The rear wing continues to open up a gap – just like it did when drivers used DRS in the past – but now the front wing also moves, with the uppermost front wing elements dropping down at the same time the rear wing’s top element does. In Singapore, there are five designated Straight Mode zones, commencing with a run along the start/finish straight, then between Turns 5 and 7, and another between Turns 9 and 10. The fourth follows between Turns 13 and 14, before concluding with a final one from Turn 15 to 16.
Meanwhile, Overtake Mode replaces DRS and is a new power mode that allows a driver to recharge more electrical energy, and generate an additional electrical power profile, so they can sustain a higher speed for a longer period. Around the Marina Bay Street Circuit, the Overtake Detection point comes as drivers head out of Turn 16, while the Overtake Activation line follows at the exit of Turn 17, available to drivers on the following lap as long as they stay within a second of the car in front at that detection point.
Due to the physical demands of the climate and circuit, drivers can lose as much as 3kg in body weight over the course of a race in Singapore. Teams and drivers often try to operate on European time to avoid jet lag and stay alert for the late sessions, meaning they have breakfast in the early afternoon and don’t go to bed until the early hours of the morning. This season will see Singapore hold a Sprint for the first time, which is set to last 21 laps.
