Formula 1 returns to the Sepang International Circuit this weekend for the first time in nine years, with Malaysia stepping in as host of the Bahrain Grand Prix after racing at Sakhir was deemed unviable following the event’s postponement earlier this season.
The race marks the second round of a triple-header that began in Azerbaijan and concludes in Singapore the following week. It is also the first time the current generation of Formula 1 cars will compete at Sepang, a circuit that held grands prix every year from 1999 through 2017.
Only 10 drivers on this weekend’s grid have previously raced at the circuit in Formula 1 competition. McLaren’s Oscar Piastri and Lando Norris are among those without prior experience at Sepang, though both have completed simulator preparation ahead of Friday’s opening practice session.
Conditions are expected to present a significant challenge. Temperatures are forecast to reach 30°C with high humidity, compounded by the threat of heavy rainfall that has historically shaped outcomes at the venue. The 2009 Malaysian Grand Prix was cut short by a storm, while the 2001 race — won by Michael Schumacher in monsoon conditions — and the 2012 edition were similarly disrupted by weather.
McLaren noted that energy deployment will be a particular focus given the circuit’s layout, which combines high-speed corners with long straights and demands careful management of performance across different sections of the lap. The team also plans to continue evaluating the upgrade package introduced in Baku, viewing Sepang’s more varied characteristics as a better testing ground than the Azerbaijan circuit’s unusual combination of slow corners and the season’s longest straight.
The Sepang International Circuit carries significant history for McLaren. Mika Häkkinen opened the venue with a demonstration run in 1999 before claiming a podium at that year’s grand prix. Kimi Räikkönen secured his first Formula 1 victory at the circuit in 2003, starting seventh and winning what would become the first of 21 career grand prix wins. Fernando Alonso also took his first victory in McLaren colors at Sepang, leading a one-two finish alongside rookie teammate Lewis Hamilton.
