Formula 1 returns to the Sepang International Circuit in Malaysia this week, presenting a significant challenge for all teams, particularly Cadillac. The American outfit is preparing for the 2026 Formula 1 Gulf Air Bahrain Grand Prix in Malaysia, a relocated event on the calendar. This marks the first time F1 has raced at Sepang since 2017.
The original Bahrain Grand Prix, scheduled for April, was postponed due to instability in the Middle East, specifically the 2026 Iran war. This conflict rendered Bahrain and neighbouring Saudi Arabia unsafe for hosting Formula 1 events.
Sepang was subsequently chosen as the replacement venue, with the race retaining its official title as the ‘2026 Formula 1 Gulf Air Bahrain Grand Prix in Malaysia’. This unique arrangement was secured through an agreement involving Formula 1, the FIA, and the governments of Bahrain and Malaysia.
Cadillac, in its debut 2026 season, fields Sergio Pérez and Valtteri Bottas as its primary drivers. The team has experienced a challenging start to the year, currently positioned at the bottom of the Constructors’ Championship.
The team has faced various ‘teething issues’, including recurring brake fires and a notable lack of overall pace. Despite these setbacks, Cadillac has shown incremental progress, particularly in closing the gap to the midfield.
Pérez, who secured his first F1 podium at Sepang in 2012, expressed anticipation for the return. He noted, ‘It’s exciting to be returning to Sepang after so many years away. It’s a demanding track.’
Valtteri Bottas has also raced at Sepang on five previous occasions, scoring points in four of those appearances. He made his Formula 1 race weekend debut at the circuit during a practice session in 2012.
Cadillac anticipates a tough weekend at Sepang, acknowledging that the circuit’s high-speed sections and long straights are areas where their Ferrari-powered package tends to lose performance.
The Sepang International Circuit, a 5.543 km track, is known for its abrasive surface, comparable to Bahrain, and its combination of lengthy straights and high-speed corners. Thermal management will be a critical factor for all teams.
Pirelli has supplied the C2, C3, and C4 compounds for the event, designated as Hard, Medium, and Soft respectively. This selection is considered a slightly more aggressive choice given the circuit’s characteristics.
Unpredictable weather is a constant concern in Malaysia. High temperatures, humidity, and the potential for sudden, torrential rain and thunderstorms are forecast throughout the weekend.
Friday’s forecast indicates an 81 per cent chance of rain and a 19 per cent chance of thunderstorms, with the probability of thunderstorms increasing to 41 per cent for Saturday.
Many current drivers lack recent Formula 1 experience at Sepang, making the practice sessions crucial for familiarisation and car setup. The circuit underwent resurfacing between Turns 6 and 12 in 2023.
Cadillac’s focus remains on operational improvement with each session. The team aims to build on recent progress during this triple-header, which follows the Azerbaijan Grand Prix.
