The Azerbaijan Grand Prix was run on a street circuit where a 2.2km straight sits alongside narrow sections bounded by walls. Sepang offers long straights too, but its sweeping corners, open layout and abrasive surface place different demands on the cars and tyres.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The change comes immediately after George Russell\u2019s victory in Azerbaijan reduced Kimi Antonelli\u2019s championship lead to 66 points. Their next contest is officially the <strong>Bahrain Grand Prix in Malaysia<\/strong>: the event has retained the Bahrain name while being held at Sepang from October 2\u20134.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th><\/th><th>Baku<\/th><th>Sepang<\/th><\/tr><\/thead><tbody><tr><td>Circuit<\/td><td>Street circuit with narrow, walled sections<\/td><td>Permanent circuit with a wider racing surface<\/td><\/tr><tr><td>Main demands<\/td><td>Straight-line performance, braking and precision near the walls<\/td><td>Balance through fast corners, braking and tyre management<\/td><\/tr><tr><td>Dry tyre allocation<\/td><td>C3 hard, C4 medium, C5 soft<\/td><td>C2 hard, C3 medium, C4 soft<\/td><\/tr><tr><td>Race distance<\/td><td>51 laps of a 6.003km circuit<\/td><td>56 laps of a 5.543km circuit<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">A different balance between straights and corners<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Baku asks teams to compromise. Reducing drag helps a car along its exceptionally long straight, but drivers still need enough grip to negotiate the slower sections without touching the barriers. Sepang\u2019s two long straights mean efficiency remains relevant, particularly under F1\u2019s 2026 power-unit rules, yet performance through sustained, faster corners becomes a larger part of the lap.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Turns 5 and 6 are among Sepang\u2019s fast sequences. The circuit also has substantial braking zones, including the final hairpin, Turn 15, before the main straight. A car that was effective down Baku\u2019s shoreline will therefore face a broader test of cornering balance, tyre behaviour and braking at Sepang. <strong>Saturday\u2019s qualifying and Sunday\u2019s race will show how the teams\u2019 Baku form translates to the Malaysian circuit.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The wider track changes the consequences of a mistake as well. Baku\u2019s walls ended Antonelli\u2019s qualifying session when he hit the barrier at Turn 1; at Sepang, drivers have more room across much of the lap and several possible lines into corners. That does not remove the cost of an error, but it changes how drivers approach a passing opportunity and where they can recover from a missed braking point.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why Pirelli has changed the tyres<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The tyre allocation provides the clearest measurable difference between the two weekends. Pirelli supplied its <strong>C3, C4 and C5<\/strong> compounds in Baku and has selected <strong>C2, C3 and C4<\/strong> for Sepang. On each weekend, those three compounds are designated hard, medium and soft respectively; a C3 tyre was Baku\u2019s hard but will be Sepang\u2019s medium.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pirelli says Sepang\u2019s asphalt is particularly abrasive and has not been resurfaced since F1 last raced there in 2017. The supplier rates the circuit\u2019s tyre wear as <em>medium<\/em> relative to the rest of the calendar. It chose the middle compound range partly to bring one-stop and two-stop race strategies closer together. The teams\u2019 practice runs will establish how those options perform with the 2026 cars. The <a href=\"https:\/\/grandepremio.com\/en\/f1\/pirelli-selects-tire-compounds-for-formula-1s-2026-return-to-malaysia\/\">compound selection for Sepang<\/a> was announced in August.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Heat and rain could change the picture<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Sepang also brings heat and humidity, with showers possible during the weekend. The early forecast points to air temperatures around <strong>33\u00b0C<\/strong> and a chance of rain on all three days, but it cannot yet establish whether a session will take place on a wet track. A shower\u2019s timing would matter as much as its presence: teams could gather practice data in one set of conditions and then face another in qualifying or the race.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">F1 last competed at Sepang in <strong>2017<\/strong>. The first practice sessions for its return take place on Friday, October 2, followed by qualifying on Saturday, October 3.

Ferrari was fined \u20ac10,000, but Hamilton will not lose grid positions over the incident. <a href=\"https:\/\/www.skysports.com\/f1\/video\/13594263\/bahrain-gp-in-malaysia-lewis-hamilton-under-investigation-for-allegedly-impeding-gabriel-bortoleto?utm_source=chatgpt.com\"> <\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why were F1 lap times at Sepang over four seconds slower than expected?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Pirelli identified low grip, dust and an abrasive surface that increased tyre sliding and degradation. Friday\u2019s benchmark was more than four seconds slower than its qualifying simulation reference, rather than four seconds slower than the 2017 race weekend.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is the 2026 Bahrain Grand Prix being held at Sepang?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The 2026 event is being staged at <strong>Sepang International Circuit in Malaysia<\/strong> while retaining the official Bahrain Grand Prix name.
