Formula 1 returns to Sepang for unusual Bahrain Grand Prix in Malaysia

Formula 1 returns to the Sepang International Circuit this weekend for the first time since 2017. The event, officially named the 2026 Bahrain Grand Prix in Malaysia, takes place between 2 and 4 October and begins an Asian double-header completed by Singapore one week later.

Malaysia was added to the calendar as the replacement venue for the Bahrain Grand Prix, with Formula 1 and the FIA confirming the arrangement in July. The race keeps its Bahrain identity and Gulf Air title sponsorship, but every competitive session will take place at Sepang.

The timing gives the event immediate championship importance. Kimi Antonelli leads the drivers’ standings with 302 points, while Mercedes team-mate George Russell is second on 236. Russell reduced the gap to 66 points by winning the Azerbaijan Grand Prix, where Antonelli recovered to fifth after crashing during qualifying.

Anyone assessing the weekend through betting sites should be cautious about placing too much weight on old Malaysian results. Formula 1 has not raced at Sepang for nine years, the technical regulations have changed substantially, and many current drivers have never completed a Grand Prix at the circuit.

Why is the Bahrain Grand Prix being held in Malaysia?

Formula 1 and the FIA selected Sepang as the host venue for the relocated Bahrain Grand Prix. The arrangement places the race between Azerbaijan and Singapore, creating a practical route into the Asian section of the calendar.

The event is unusual because the official Grand Prix name refers to a different country than the host circuit. Bahrain retains its connection to the weekend, while Malaysia provides the track, infrastructure and local organisation needed to stage the race.

Sepang already has considerable Formula 1 history. The circuit hosted its first Grand Prix in 1999 and remained on the calendar until 2017. That final race was won by Max Verstappen, who passed Lewis Hamilton early and controlled the remainder of the afternoon.

The current layout measures 5.543 kilometres and Sunday’s race covers 56 laps, producing a total distance of 310.398 kilometres. Sebastian Vettel holds the official race lap record of 1 minute 34.080 seconds, set during the 2017 event.

Those figures offer a basic reference, although direct comparisons with 2017 will be limited. The present cars use different power units, aerodynamics and tyres, while the circuit has undergone maintenance ahead of Formula 1’s return.

What makes Sepang difficult for drivers and teams?

Sepang combines long straights with extended corners that place sustained energy through the tyres. The first and final turns create clear overtaking opportunities, but much of the lap depends on maintaining balance through faster changes of direction.

The opening section begins with heavy braking into a tight right-hander. Turn 2 follows immediately and can compromise the exit if a driver enters too aggressively. Cars then build speed through a more flowing part of the lap before reaching another group of technical corners in the middle sector.

The two long straights near the end create a difficult set-up decision. Reducing wing angle improves straight-line speed and helps overtaking, yet the car still needs enough downforce to protect the tyres and remain stable through the quicker corners.

Track temperature adds another variable. Sepang has previously recorded surface temperatures above 60C, and the combination of heat and long loaded corners can accelerate tyre wear. Drivers who slide early in a stint may lose performance well before their planned pit stop.

The physical challenge is also significant. High humidity reduces the body’s ability to cool itself, while cockpit temperatures remain intense throughout the 56-lap race. Drivers must manage hydration carefully and maintain concentration during a Grand Prix that can last close to two hours.

How could tyre strategy decide the race?

Pirelli has selected the C2, C3 and C4 compounds for the weekend. These sit in the middle of its 2026 tyre range and are one step harder than the allocation used in Azerbaijan.

The choice reflects Sepang’s demanding corner loads and abrasive conditions. Teams need a tyre capable of surviving the high-energy sections without removing the strategic difference between compounds.

Two-stop strategies were common during earlier Malaysian Grands Prix, while some races required three stops. Modern tyres behave differently, so practice data will be more useful than historical strategy. Even so, a simple one-stop race appears less certain here than at many recent circuits.

Friday running will carry added value because teams have little recent information gathered in real conditions. Simulator work can estimate loads and lap times, but it cannot perfectly reproduce the circuit surface, heat or rapid changes in grip.

Additional surface levelling took place during September to remove irregularities in the asphalt. That work may affect grip in specific sections and could change how quickly the racing line develops during practice.

An early Safety Car would open several strategic options. Drivers who start on the medium tyre may be able to change compounds without losing as much track position, while teams committed to a shorter opening stint could gain flexibility. A badly timed interruption could also trap a leading car behind rivals using fresher tyres.

Could rain disrupt Formula 1’s Sepang return?

Warm and humid conditions are expected throughout the weekend, with a chance of showers. Tropical weather can change quickly around Sepang, sometimes affecting one section of the circuit before the rest becomes fully wet.

That creates a difficult tyre decision. The lap is long enough for conditions to change while a driver is still on track, and returning to the pits at the wrong moment can cost substantial time. Teams must decide if a shower will intensify or disappear before intermediate tyres become worthwhile.

Sepang has produced memorable wet races before. The 2009 Grand Prix was stopped early after torrential rain, while the 2012 event produced an unexpected victory for Fernando Alonso after changing conditions disrupted the normal competitive order.

Current drivers have had limited wet running during the 2026 season. If rain reaches qualifying or the race, teams will need to learn quickly how the latest cars behave on Sepang’s resurfaced sections.

Visibility may become as important as grip. Heavy spray on the long straights can make it difficult for drivers to see braking boards or slower cars ahead, increasing the possibility of Safety Car periods or a red flag.

Can George Russell reopen the championship contest?

Russell arrives in Malaysia after one of his strongest weekends of the season. He took pole position in Baku by eight-tenths of a second and then defeated Verstappen by only one-tenth at the finish, completing his first Formula 1 grand slam.

The victory was Russell’s third of 2026 and reduced Antonelli’s advantage by 15 points. Antonelli still holds a substantial lead, but his qualifying crash showed how quickly a difficult weekend can alter the championship.

Antonelli has 302 points after eight victories, while Russell has 236. Lewis Hamilton sits third on 199, followed by Lando Norris on 186 and Charles Leclerc on 179. Verstappen’s second place in Azerbaijan moved him to 163.

Eight rounds remain, leaving enough points available for the order to change. Russell still needs several strong results combined with lower finishes for Antonelli, but another victory at Sepang would carry the contest into Singapore with greater pressure on the leader.

Mercedes has more control in the constructors’ championship. The team leads Ferrari by 160 points, with 538 against 378. McLaren holds third on 306, while Red Bull has 263.

Which other drivers could challenge at Sepang?

Verstappen’s Baku performance suggested Red Bull has made progress. He finished only one-tenth behind Russell, while team-mate Isack Hadjar completed the podium after returning following six weeks out with a wrist injury.

Ferrari needs a stronger conversion of its speed. Leclerc qualified second in Azerbaijan but did not finish on the podium, while Hamilton remains third in the championship despite not winning since Barcelona in June. Sepang’s mix of heavy braking and faster corners should give the team a clearer test of its overall balance.

McLaren left Baku after a difficult weekend marked by mistakes and lock-ups. Norris and Oscar Piastri now need to establish if that performance was specific to the street circuit or evidence of a broader problem.

Sepang should produce a more complete assessment than Baku. Its long corners test aerodynamic stability, the straights expose drag and the heat examines tyre control. A car that performs well across the entire lap is likely to remain competitive at several of the remaining circuits.

Formula 1’s Malaysian return was not part of the original shape of the season, yet it arrives at an ideal point in the championship. Russell has regained momentum, Antonelli faces his first immediate response after a difficult weekend, and the teams must prepare for a circuit missing from the calendar since 2017. The unusual Bahrain Grand Prix in Malaysia could influence far more than its name suggests.
