Key Storylines at Sepang: Bahrain Grand Prix 2026 in Malaysia Preview

This Bahrain Grand Prix 2026 in Malaysia preview starts at a circuit Formula 1 hasn’t raced at since 2017, with Sepang hosting round 16 under the Bahrain name. Kimi Antonelli arrives 66 points clear of George Russell after the worst weekend of his season, and Russell comes in off his first win since Austria. Mercedes finally bring the W17 upgrade they held back through Baku, and Red Bull come off their first double podium of 2026 with Max Verstappen still chasing a first win. Rain or thunderstorms are forecast on all three track days.

Mercedes Finally Bring the W17 Upgrade

Mercedes held the package back through Baku and still won there. Russell took pole and beat Verstappen to the flag by 0.196 seconds, on a weekend where Mercedes declared no upgrades at all. Their last major package came in Montreal in May. Since then it’s been smaller, circuit-specific changes while Ferrari and McLaren developed harder. The major package now arrives at Sepang.

Qualifying is the target. Mercedes took pole at each of the opening 10 rounds, then went four races without one before Baku, Norris taking three of those four. Shovlin said before Baku that the updates were “going to come Malaysia onwards and hopefully we’ll make a decent step.”

What’s in the package isn’t public yet. Thursday’s FIA car presentation document will show the parts. I won’t guess at floor or bodywork changes until then.

There’s a title fight inside the Mercedes garage as well. Antonelli had the worst weekend of his season in Baku, crashing in qualifying, starting 16th and recovering to fifth. “Today was about damage limitation,” he said. Russell’s win was his first since Austria in June and cut the gap to 66 points. “Win every race! That’s the game plan,” Russell said, adding that “now we’re getting to crunch time.”

Red Bull’s Baku Step Meets a Permanent Circuit

Red Bull brought their final major 2026 package to Baku. New floor, revised sidepods and related aero changes, on both cars. It worked straight away in Baku. Verstappen finished 0.196 seconds behind Russell and Hadjar came home third on his return from a wrist injury, Red Bull’s first double podium of the season.

The race pace backed that up, with Verstappen’s fastest lap second only to Russell’s, 0.077 seconds slower, and Hadjar fourth quickest. “It’s better than when I left it in Budapest, so I’m pretty happy!” Hadjar said after his first day back. Waché was just as clear about the order after the opening day of practice: “Clearly, Mercedes are in front of us after today, especially on the short runs.”

Sepang’s mix of medium and high-speed corners is very different from Baku’s straights and slow Old Town section. And there’s nothing more coming. Red Bull say the Baku package is likely their final major update of 2026, with most resources already moved to 2027. Verstappen also needed a power unit change within his allocation after an issue was found in Baku.

Verstappen still hasn’t won in 2026. “We really maximised the result today and we will, of course, keep trying for a win,” he said. Red Bull sit fourth in the Teams’ Championship on 230 points, 76 behind McLaren. Another two-car result near the front would make Baku look like a shift in the order rather than a street-circuit spike.

Ferrari’s Development Gap and the Horner Noise

Ferrari are second in the Teams’ Championship on 358 points, 52 clear of McLaren. Leclerc finished fourth in Baku and Hamilton sixth, and Leclerc was blunt about where Ferrari are.

Ferrari brought no declared aerodynamic upgrades to Baku while McLaren and Red Bull brought substantial packages. On the power unit, Ferrari qualified for ADUO development because their unit was assessed as more than 4% behind the benchmark, with upgrades arriving in Austria and Monza. The Monza step brought a gain but didn’t remove the deficit, and Vasseur has cautioned that straight-line speed isn’t an engine-only measure, with drag and weight in there too. “We’ve got things in the pipeline, but I don’t know what the others have in the pipeline,” Leclerc said.

Hamilton’s race showed the tyre window problem. “Even through the whole race the tyres were just switching on, switching off, switching on, switching off,” he said. He said Ferrari would review energy management before Sepang.

Off track, Horner told The Times that Ferrari is the one team he’d consider going back to without an ownership stake. “Ferrari is the biggest brand in Formula 1. It’s the dream. And arguably it’s the sleeping giant of Formula 1,” he said. Vasseur hit back. “It is not in my hands, and Horner is looking for a job, everybody knows, everywhere, but what can I do?” Motorsport.com reports Vasseur’s contract runs to the end of 2027, and there’s no evidence Ferrari have agreed anything with Horner or decided to replace their team principal, so for now it stays speculation.

Alpine’s Baku Fallout Follows Them to Sepang

Both Alpines started inside the top 10 in Baku and both were in the points when the first Safety Car came out. Gasly held seventh. Colapinto was 10th, fighting Norris. At the Lap 36 restart Colapinto arrived at Turn 1 too fast, locked the fronts and hit Gasly, who was pushed into Norris. All three out.

The stewards ruled Colapinto wholly or predominantly to blame. He’d already retired, so the 10-second penalty became a five-place grid drop for Sepang. “It was a big mistake on my side and it should not happen,” Colapinto said. Gasly accepted his apology. Briatore said he wants “to take time to reflect on it and consider what course of action should be taken.” He hasn’t said anything about Colapinto’s seat.

Alpine sit sixth in the Teams’ Championship on 68 points, nine behind Racing Bulls on 77. Both cars were on course to score in a midfield fight that close. “In terms of our race up until that point, the car felt good, we had strong pace,” Gasly said. Both cars running around the top 10 again on a permanent circuit would back that up, with Colapinto starting five places down from wherever he qualifies.

Circuit Overview

Hermann Tilke designed Sepang as part of Malaysia’s industrial push in the 1990s, and it opened for the first Malaysian Grand Prix in 1999. Eddie Irvine won that one for Ferrari, with Michael Schumacher back from injury to help his title bid.

The Malaysian Grand Prix ran every year until 2017, when Verstappen won the last race here. This year Sepang hosts the Bahrain Grand Prix instead, arranged by Formula 1 and the FIA to save a race that otherwise wouldn’t have happened.

The 5.543km layout is wide. Long straights, heavy braking zones and fast, flowing corners give drivers more than one line to attack from. The long sweep through Turns 5 and 6 is the standout, and the Turn 15 hairpin feeds straight onto the main straight. Heat and humidity are part of every lap, and a tropical downpour can change conditions in minutes. The race runs 56 laps, 310.398km, and the lap record is Sebastian Vettel’s 1:34.080 from 2017.

Tyre Talk

Pirelli bring C2 Hard, C3 Medium and C4 Soft, the middle of the 2026 range. Sepang rates as medium stress on Pirelli’s scale across the calendar. The bigger variable is the surface.

Nobody has 2026 data here. The only F1 reference is 2017, with a completely different generation of car and tyre. The asphalt is the one thing that hasn’t changed since. Every team arrives building its strategy from simulation, so Friday’s long runs carry more weight than usual.

Every driver’s allocation includes mandatory sets, one C4 for qualifying and one each of C2 and C3 for the race. Those sets have to be there, but any compound can still run in qualifying or the race. Pirelli want the two-stop close enough to the one-stop that teams have a real choice. Full compound and strategy detail follows in the tyre preview this week.

Weather

Rain could be the story all weekend. Highs of 32°C every day, 24°C overnight. Friday brings spells of rain, with more late on, and a 75 percent rain chance. Saturday has an afternoon thunderstorm or two at 63 percent, with more storms possible into the evening. Sunday shows a few afternoon showers and a little rain late, 75 percent again.

FP1 and FP3 run at 12:30 local, FP2 and qualifying at 16:00, and the race starts at 15:00, all in the afternoon window where the forecast puts the showers. A shower during qualifying makes track evolution and timing decisive across Q1, Q2 and Q3. Rain in the race would widen the strategy window. It’s still several days out and Sepang’s weather changes quickly, so none of this is guaranteed.

Session Timings: Bahrain Grand Prix 2026 in Malaysia

Coffee Corner Take

Mercedes won Baku without the upgrade and they’re bringing it anyway. To me that’s about qualifying, and Shovlin’s said as much. Antonelli’s 66 points is a big lead, but Russell’s already calling it crunch time, and a car that’s back fighting for pole every Saturday helps the driver doing the chasing. With storms forecast right on the session times at Sepang, Saturday could decide a lot.

Baku was a street circuit. Sepang’s a permanent one, and Red Bull have nothing else coming this year while the rest keep developing. If Verstappen and Hadjar are Mercedes’ closest threat again here, I’ll believe the step is real.

The Horner stuff is noise to me. Leclerc saying he doesn’t know if what’s in the pipeline is enough worries me more. If Ferrari can’t close the gap on track, the Vasseur questions won’t go away, whatever Horner says in The Times.

Pirelli picked C2 to C4 to open up a two-stop, on a surface F1 hasn’t raced on in nine years, with rain forecast across every session. No team has 2026 data here. A weekend like this can open the door for Verstappen, who still hasn’t won this year, and it could make Colapinto’s five-place drop cost him less than it should.
