Malaysia's Sepang circuit is making a one-off return to the Formula 1 calendar as a proxy host for the Bahrain Grand Prix, bringing challenges both familiar and new. The hot and humid conditions, along with the daily late-afternoon rain downpour, act as a Proustian madeleine for those with previous experience of this venue. For others – including most of the drivers on the grid – these are conditions they have only read about.
Sepang occupies a significant place in F1 history since it signalled grand prix racing's aggressive expansion eastward under the Bernie Ecclestone regime. This was the first of many grand-scale facilities with statement architecture, paid for by governments who wanted to put their countries on the map. It also set the template for the kind of track designed by the architect who came as part of the package: Hermann Tilke.
For Sepang's cameo appearance in 2026, the F1 cars are entirely different so there are many unknowns. Only the ambient heat and humidity, and the abrasiveness of the track surface, are well understood. Built to withstand the harsh weather and provide quick drainage, the aggregate has a very open texture. It's expected that tyre degradation will be more of a factor here than other tracks this season.
"We come to an incredible circuit now," said Fernando Alonso, who claimed his maiden F1 pole position at Sepang in 2003. "It's going to be sad, the middle sector, because we cannot use the battery there – if not, you don't have [sufficient charge] for the three consecutive straights." So the cars are likely to be quite slow through the middle sector as a result.
