Brazilian Sauber driver Gabriel Bortoleto will debut at the Marina Bay Circuit this Sunday, October 5, 2025, in Singapore. The night race, the 18th round of the Formula 1 season, marks new territory for the 22-year-old rookie. He expressed eagerness for the urban track’s 19 technical corners, which demand intense physical preparation due to the hot, humid climate.
Held under artificial lights since 2008, the race is F1’s first night event. Bortoleto has 18 points in the drivers’ standings, ranking 18th after an 11th-place finish in Azerbaijan two weeks ago. His goal is to quickly adapt to the track and seize opportunities in the midfield.
Team principal Jonathan Wheatley emphasized that the weekend tests the entire Sauber team’s endurance.
- 4.94 km track with short straights and close walls, prioritizing precision over raw speed.
- Average nighttime temperature of 30°C, with humidity above 80%, impacting driver hydration.
- 17 editions with seven different winners, including Sebastian Vettel’s record of five victories.
Simulator prep sets initial pace
Bortoleto logged hours in the simulator to map Marina Bay’s 19 corners. The urban layout requires fine-tuning the C45 car, which performs better on tracks with long straights.
He aims to maximize performance from Friday’s free practice, October 3.
Sauber’s expectations for the weekend
Sauber arrives confident after a competitive showing in Baku, where Bortoleto challenged rivals. Wheatley stressed capitalizing on midfield opportunities, as seen in the last seven races.
The Briton anticipates a grueling GP, focusing on tire strategies for the uneven asphalt. Bortoleto scored points in four of the last seven races, climbing from starting positions in Monza and Zandvoort.
Marina Bay’s unique features
The street circuit integrates Singapore’s skyline, with low-speed corners demanding high downforce. Drivers face muscle fatigue over 62 laps due to prolonged seating in high temperatures.
Artificial lighting, installed in 2008, creates shadows affecting visibility in fast sectors. Pirelli data suggests C3, C4, and C5 compounds, avoiding C6 to prevent overheating on the asphalt.
Physical adaptation to Asian climate
Bortoleto adjusted training to mimic 30°C heat and humidity, common in Singapore even at night. The physical demand exceeds European circuits, with drivers losing up to 3 kg during the race.
He prioritizes energy management to stay sharp in technical corners like 10 and 19. Sauber will optimize cockpit cooling to reduce discomfort.
Recent form boosts confidence
Bortoleto climbed from 13th to 11th in Azerbaijan, showcasing strategic overtakes with fresh tires. This damage-free performance offers lessons for urban tracks like Marina Bay.
Sauber aims to repeat a top-10 finish, exploiting rivals’ weaknesses in hot conditions.
Tire strategies for tight layout
Pirelli predicts high wear in Marina Bay’s corners, with most races requiring two pit stops. Bortoleto tested sequences in the simulator, alternating softs for qualifying and mediums for long stints.
The C45 manages initial tire warm-up well but needs monitoring in heavy braking zones.
Calendar ramps up for season’s final stretch
After Singapore, Formula 1 heads to the United States, Mexico, and Brazil in coming weeks. Bortoleto faces a series of new tracks, starting with the 4.94 km Asian circuit. McLaren leads the constructors’ standings with 623 points, potentially clinching the title with a podium.
Oscar Piastri tops the drivers’ championship with 324 points, followed by Lando Norris with 299. Gabriel Bortoleto has 18 points in the 2025 Formula 1 drivers’ standings (402 words).
