Singapore set for 2027 layout change, but not the one Hamilton asked for

The circuit's limited overtaking opportunities came under renewed scrutiny following Saturday's inaugural Singapore Sprint, which featured little on-track passing but several collisions and a record nine retirements. While drivers expressed differing opinions on the layout, attention has also turned to the planned changes and what they could mean for racing at Marina Bay.

The straight was never designed to help overtaking. Organisers announced in October 2022 that the track would change because of the redevelopment of The Float at Marina Bay into "NS Square", a community and events venue. As part of that, Turns 16 to 19 of the previous layout will now be re-aligned into a 397.9m long straight, bringing the total number of turns to 19.

Although the 2023 modifications appeared to be aimed at improving overtaking, the removal of four corners was actually driven by construction work unrelated to Formula 1. The changes also resulted in the demolition of one of Marina Bay's most recognisable features: the 27,000-seat Bay Grandstand, beneath which the cars previously raced. Both the grandstand and the corners surrounding it were removed in 2023 to make way for the new development.

The project has also experienced several delays. Initially scheduled for completion by the end of 2026, the construction timetable was subsequently extended to 2027, as announced by Singapore's Ministry of Defence and Ministry of National Development. Once completed, NS Square will provide a permanent venue dedicated to recognising National Service while also hosting major public events.

Hamilton is not alone in his preference for the revised Marina Bay layout. During the drivers' briefing in 2023, those present unanimously supported the changes and suggested making them permanent. However, the final decision rests with the Singapore authorities rather than the FIA.

The main obstacle is commercial. The introduction of the new layout meant bypassing the large permanent Bay grandstand, reducing the circuit's overall spectator capacity by approximately 25,000 seats, or 17%. Restoring that section would allow organisers to accommodate more fans, making the return of the rebuilt grandstand an important priority for the event's promoters.

Singapore GP's Colin Sin spoke plainly about the empty seats at the time.

The new NS Square venue has been designed to accommodate the Singapore Grand Prix, with plans for a 30,000-seat grandstand overlooking a section of the circuit. During the race weekend, Formula 1 cars will pass directly in front of the spectators, bringing the track back into an area currently bypassed by the temporary layout.

The construction project also means that the configuration introduced in 2023 cannot remain in place permanently. The straight added that year occupies land earmarked for the new development, making further changes to the Marina Bay circuit necessary once construction progresses.

However, the planned changes do not necessarily mean a return to the original, slower section of the Marina Bay circuit. Sin suggested that a compromise could be reached, with the track once again passing around the Bay grandstand but featuring a modified layout with faster corners. He also indicated that the current configuration could remain in place for the 2027 Singapore Grand Prix, depending on when construction work is completed.

The final layout has yet to be confirmed, although Singapore's existing agreement with Formula 1 runs until the end of 2028. For now, the organisers appear keen to restore the section around the grandstand rather than introduce additional straights. Such a decision would contrast with the changes requested by drivers hoping for more overtaking opportunities at Marina Bay.
