Malaysia’s Sepang circuit is making a one-off return to the Formulation 1 calendar as a proxy host for the Bahrain Grand Prix, bringing challenges each acquainted and new.
The recent and humid situations, together with the each day late-afternoon rain downpour, act as a Proustian madeleine for these with earlier expertise of this venue. For others – together with a lot of the drivers on the grid – these are situations they’ve solely examine.
Sepang occupies a big place in F1 historical past because it signalled grand prix racing’s aggressive growth eastward below the Bernie Ecclestone regime. This was the primary of many grand-scale services with assertion structure, paid for by governments who wished to place their international locations on the map.
It additionally set the template for the type of observe designed by the architect who got here as a part of the bundle: Hermann Tilke. His perception was that extensive tracks with lengthy straights adopted by sharp corners would facilitate overtaking organically by upsetting drivers to make errors. Tilke’s detractors describe his style as bland and failing to ship on the promise of overtaking.
The draw back of state backing is that political winds change. In Malaysia, ticket costs set past the attain of most locals – only one would value the common particular person’s month-to-month wage – meant largely empty grandstands year-in, year-out.
Not the advert the nation wished. In 2017, after 18 years as a fixture on the calendar, Malaysia terminated its internet hosting deal a season early.
There are actually extra followers this 12 months than was once the case at this venue

For Sepang’s cameo look in 2026, the F1 automobiles are completely totally different so there are various unknowns. Solely the ambient warmth and humidity, and the abrasiveness of the observe floor, are nicely understood.
At the very least one driver has likened the observe floor to sandpaper. Constructed to face up to the tough climate and supply fast drainage, the combination has a really open texture.
Tyres produce grip by means of a course of often called hysteresis. Rubber is a viscoelastic materials: not like a completely elastic substance, it would not instantly spring again absolutely to its unique form as soon as compression forces are eliminated. As a tyre rotates, the outer layer is compressed in opposition to the observe floor and a few of the kinetic vitality is misplaced as warmth as the fabric tries to return to its unique state.
The rougher the floor, the upper the temperatures. For that reason it is anticipated that tyre degradation can be extra of an element right here than different tracks this season. That can come as some reduction after an Azerbaijan Grand Prix which was a nailed-on one-stop race, even with the comfortable tyre.
Curiously, whereas Pirelli has leaned in the direction of the tougher finish of its compound household, it hasn’t introduced the toughest tyre of all. As a substitute the alternatives from exhausting to comfortable are the C2, C3 and C4 – only one step tougher than in Baku.
Sepang’s format, with lengthy straights and sharp corners, is more likely to be comparatively deterministic in the way in which the groups will method vitality harvesting and deployment – doubtlessly alongside related strains to China, the place there was loads of the so-called ‘yo-yo racing’ followers and drivers dislike. However there are some recommendations this will likely not really be the case.
“We come to an unbelievable circuit now,” mentioned Fernando Alonso, who claimed his maiden F1 pole place at Sepang in 2003.
“It is going to be unhappy, the center sector, as a result of we can’t use the battery there – if not, you do not have [sufficient charge] for the three consecutive straights, you realize, from Flip 14 to the final nook, then final nook to Flip 1, Flip 2 to Flip 4, you must use the total 100% battery on these three straights, so the remainder is simply charging the battery.”

So the automobiles are more likely to be fairly gradual by means of the center sector in consequence – however anybody who makes use of electrical enhance to grab an overtake can pay for it on the finish of the lap.
When deploying {the electrical} motor, the present automobiles put fairly savage quantities of vitality by means of the rear tyres, so the chance of damaging them by inflicting the floor temperatures to spike is as worrying for the engineers because the longer-term results of thermal degradation. This may also have an effect on how the groups method deployment right here.
“I feel the large distinction on this circuit in contrast with different so-called yo-yo circuits is the tyre overheating,” mentioned George Russell.
“So circuits similar to Melbourne, Silverstone, Monza, there wasn’t really that a lot tyre overheating from the floor. Canada as nicely. In order that type of allowed the drivers to remain a bit of bit nearer inside that one second [which grants access to additional power through overtaking mode].
“Even in Baku it was fairly cool, the drivers might keep shut. Whereas right here, floor overheating goes to be an enormous factor. You will be overheating the tyres even on the outlap of a qualifying session, which can make it more difficult to observe nearer and to re-attack as soon as you have been overtaken. However that is a complete unknown at present.”
After a number of races with little or no degradation, channelling groups into broadly related methods, this venue might generate some strategic selection. If that’s the case, it could have one thing in frequent with the observe which often hosts the Bahrain Grand Prix, one other one with a tough floor hostile to tyre life.
This may increasingly even be the primary correct outing for F1’s wet-weather tyres. Right here there are extra unknowns, given the long-standing fears that the brand new intermediate tyre is a bit of too exhausting, and vulnerable to not warming up shortly sufficient.
“It is going to be take a look at for positive if it rains,” mentioned Carlos Sainz. “A superb take a look at for the rules additionally as a result of I feel with all the problems we have now with downshifts, with harvesting, energy, variability, nook to nook, the moist goes to be a problem for positive.
“Each from a tyre standpoint – from what I heard from those who have run them, this 12 months’s moist tyre and inter-tyre are tough – plus the ability unit issue [ie large delivery of torque in slippery conditions], it is going to be for positive take a look at.”
In 2009 the race begin was moved to a later time of 15:00 native, as it is going to be this 12 months, and a downpour induced the race to be stopped early. When situations did not enhance, the restart was aborted

In Malaysia you possibly can reliably guess on a torrential downpour at round 4 o’clock within the afternoon. Generally it arrives early; generally it clears up shortly, by which case the warmth will dry the observe fairly shortly.
However there are circumstances the place it may be raining however, owing to the warmth drying the observe floor, not moist sufficient even for intermediate tyres. This was the case within the 2009 working of the Malaysian Grand Prix.
Most individuals do not forget that as a result of it was one of many comparatively few races in F1 historical past to have been red-flagged and never restarted earlier than the total race distance was accomplished. The race begin was put again to fifteen:00 native that 12 months for the co nvenience of European TV viewers, so a drenching was just about inevitable – and it ought to have figured within the ideas of those that scheduled the race on the similar time this 12 months.
However what many individuals neglect is that for no less than 10 laps earlier than the rain turned biblical, those that had made an early swap to moist tyres suffered as their tyres overheated. Nonetheless, given the overall lack of working on Pirelli’s wet-weather rubber this 12 months, this space stays an unknown.
“The one factor I keep in mind from Japan [where he tested the wet tyres] is that the tyres have zero grip,” mentioned Isack Hadjar. “It might make the racing very harmful with numerous water. So, I might positively welcome any aggressive session to be a rain session and qualifying. However in the mean time, for the race, with all this vitality, I feel it could create a little bit of chaos.
“I do not suppose we’re a lot prepared for that. However positively qualifying – why not?”
