Formula 1 is returning to Sepang International Circuit for the first time since 2017, but with a most unusual twist. The race on 4 October 2026 will be held in Malaysia while carrying the Bahrain Grand Prix name, roughly 6,000 km from Bahrain.
It sounds bizarre, but it is not without precedent. The 1982 Swiss Grand Prix was held in France, while the Luxembourg Grand Prix took place at Germany’s Nürburgring in 1997 and 1998. This time, Bahrain Grand Prix management has put together a deal that allows it to bring its sponsors and clients to Asia after the Bahrain and Saudi Arabian rounds earlier in the season were ruled out by the Middle East conflict.
It will be the 16th round of the 2026 championship, and it could well become the most gruelling weekend of the year for drivers, teams, media and trackside fans.
A Bahrain Grand Prix at Sepang

Sepang is a familiar Formula 1 venue, having hosted the Malaysian Grand Prix from 1999 through to 2017. Yet it has not been sitting ready for a return. An FIA delegation inspected the facility earlier in 2026, and work has been underway at pace to bring the circuit back to Formula 1 standard.
That preparation has involved substantial work around the track, grandstands and infrastructure. A reported US$7 million cabling bill was also needed to make live television coverage possible. Who would pick up that cost was unclear at one point, but it will all need to be resolved before first practice.

The circuit’s famous Malaysian flag artwork is staying exactly where it is. That is rather fitting. The event may be marketed as the Bahrain Grand Prix, but there will be no mistaking where the race is actually taking place.
The Heat and Humidity Could Be Brutal

I was at Sepang for the final race in 2017, my first season photographing Formula 1. I remember it being wet, humid and very hot. When it was not bucketing down with rain, the heat was relentless.
This race could be even tougher than Singapore because it will be run in daylight. Singapore is a night race, which saves a few degrees. At Sepang, cockpit temperatures could sit between 40°C and 50°C, with humidity around 80%. Track temperatures could reach 60°C, putting extraordinary stress on the Pirelli tyres.
The closest recent benchmark is Qatar in 2023, when the conditions were brutal enough to cause serious physical problems:
- Esteban Ocon vomited in his helmet during the race.
- Logan Sargeant retired on lap 41 after severe dehydration.
- Lance Stroll said he was passing out in the car.
- Stroll and Alex Albon both struggled to get out of their cars after the finish.
The FIA is expected to classify both Sepang and Singapore as heat-hazard events. Teams will therefore be required to fit driver cooling systems to the cars, although wearing a cooling vest remains optional. It will be fascinating to see who chooses to wear one and who does not.
Haze Is More Than a Visibility Problem

Heat and humidity are only part of the concern. Kuala Lumpur has also been dealing with poor air quality caused by smoke from forest fires in Indonesia. The air pollutant index has recorded unhealthy readings above 170, and other sporting events in the region have already been cancelled because of the haze.
The immediate effect is unpleasant enough. Face masks may be required, and wearing one in high heat and humidity is no fun at all. But the haze has wider consequences for a Formula 1 weekend:
- It could reduce what people at the circuit can actually see.
- It could affect the clarity of television pictures and trackside photography.
- It may make conditions harder for teams, officials and all event staff working outdoors.
- Most importantly, it could ground the medical helicopter if visibility becomes too poor.

Formula 1 regulations require a medical helicopter to be able to reach a hospital within a strict time limit. If it cannot fly, on-track running can be affected. China in 2017 provided the example, when second practice had to be abandoned because the medical helicopter could not operate in poor visibility.
Rain can help reduce the amount of haze, so the Bahrain Grand Prix organisers will be hoping for plenty of it. The forecast suggests rain is likely, although whether it will be enough to clear the air remains to be seen. The haze could also drift to Singapore and potentially affect the Grand Prix there a week later.
Sepang Is a Properly Demanding Circuit

Sepang is one of Formula 1’s more demanding circuits, and rightly so. It was one of Hermann Tilke’s earliest F1 designs, measuring 5.5 km with 15 corners and eight straights. The layout combines long flat-out sections, heavy braking zones, slow traction-limited corners and quick direction changes that punish any instability in the car.
The opening sequence is particularly inviting. Drivers have a long run from the start before arriving at a tight, multi-apex slow corner. It encourages heavy late braking and the sort of divebomb moves often seen at the opening turn in China.
But Turn 15, the final hairpin around Sepang’s distinctive grandstand, should be one of the prime overtaking spots. The recipe is straightforward:
- Stay close through the preceding section.
- Duck out at the last possible moment.
- Launch down the inside.
- Brake brutally late into the hairpin.

Anyone positioned near that final sector could be in for some cracking racing. Yet the same layout will place sustained demands on brakes and tyres, particularly when the track surface is baking and the cars are being worked hard in dirty air.
Sepang last hosted Formula 1 in 2017. Pierre Gasly made his F1 debut there, replacing Daniil Kvyat at Toro Rosso. Max Verstappen won the race, Lewis Hamilton finished second and Daniel Ricciardo was third. Remarkably, 10 drivers from that 2017 grid are still competing in 2026, and Verstappen has every chance of claiming Malaysian victories 9 years apart.
Thunderstorms Could Turn Everything Upside Down

Rain is likely to be the biggest variable of all. Sepang is famous for thunderstorms and a typical Malaysian day can change quickly. The morning may be bright, hot and humid. Then clouds build, the heavens open in a torrential downpour and, just as suddenly, the rain eases again.
This is not simply a question of whether to bring waterproof gear. The teams have had little opportunity to understand how the new 2026 cars behave in proper wet conditions. Rain during a session or race could make strategy a complete lottery.
There is history here. The 2009 Malaysian Grand Prix was stopped on lap 31 because of flooding. With the 2026 race scheduled for the afternoon, the likelihood of rain is significant, and a sudden shower could produce sensational racing or utter chaos, perhaps both.
Getting to Sepang Matters

Sepang is not in the heart of Kuala Lumpur. It sits around 60 km south of the city centre and right beside Kuala Lumpur International Airport. That matters enormously during a Formula 1 weekend.
Driving from central Kuala Lumpur to the circuit can take roughly an hour in ordinary conditions, and that is before F1 traffic is added to the equation. A city-based stay may sound appealing, but spending up to 3 hours a day in a car is hardly ideal during a hot and draining race weekend.
Staying close to the airport makes far more sense. The Sama Sama Hotel is only around 10 minutes from the circuit and is popular with drivers for precisely that reason.

A Huge Challenge, but a Welcome Return

Local reaction to Formula 1 returning to Malaysia has been enormous. The race was a genuine surprise, and there is clearly a great deal of enthusiasm for having F1 back in this part of the world.
For everyone involved, though, this will be hard work. The drivers face punishing cockpit temperatures, humidity, a technically demanding circuit and the possibility of rain. Teams have cooling systems, tyre behaviour, wet-weather performance and ever-changing strategy to manage. Meanwhile, haze could affect visibility and even the operational ability of the medical helicopter.
Then there are the people working outdoors all weekend. Managing hydration will be vital. Sepang in October can serve up heat, humidity, thunderstorms and haze in a single event, which is why this race has every chance of being the most difficult Formula 1 weekend of 2026.

That is also exactly why it could be enthralling.
