F1 returns to Sepang after nine years as Mercedes struggles for pace on opening day in Malaysia
Mercedes ended the first day of the Bahrain Grand Prix weekend in Malaysia seventh and eighth, its new upgrade package bringing overheating tires instead of the expected lap-time gain.

What Happened
Formula 1 returned to the PETRONAS Sepang International Circuit in Malaysia on Friday for the first time in nine years, within the Bahrain Grand Prix weekend. Warm and humid weather greeted the drivers and, combined with the track's aggressive asphalt and its medium-speed to fast corners, made for a hard test of the tires. Both Mercedes drivers used the medium and soft compounds in both practice sessions.
- FP1: P2, 25 laps, 1:37.903 (medium, soft, medium) — FP2: P7, 28 laps, 1:38.020 (medium, soft)
- FP1: P5, 23 laps, 1:38.580 (medium, soft, medium) — FP2: P8, 28 laps, 1:38.060 (medium, soft, medium)
George Russell finished the first session in second place and Kimi Antonelli was fifth. Between the sessions the team concentrated on improving tire management on the long runs, and because rain showers were expected it brought its second-session programme forward. Neither driver could make the most of their single fast lap on the soft tires, and the team ended the day in seventh and eighth — positions it called not very meaningful. The brought-forward programme did give the team plenty of long-run data, with Russell running on the soft tires and Antonelli splitting his laps between the soft and medium compounds.
“It was a really cool experience to go out on track here at the PETRONAS Sepang International Circuit for the first time. I have never driven here and it is great to make up for that on this legendary track. The support we received as a team was fantastic too, so thank you to all the fans who were here today and who will still come over the weekend. In these warm conditions combined with the aggressive asphalt and the characteristics of the circuit, tire degradation during practice was high. We had expected that at the start of the weekend. The strong overheating of the tires does, however, neutralise a little the performance of the extra downforce we gained with our update. The cars are in a completely different window than usual. I do not think we set our car up today quite as it would have needed to be. We will try to get on top of that overnight. If we manage it, we can hopefully fight right at the front for the rest of the weekend.”
“We had a decent first day on track here in Malaysia. The PETRONAS Sepang International Circuit is incredible to drive — it is fast and flowing, really super cool. We were able to complete a lot of laps in both sessions and we worked through our entire programme. We collected a lot of data that will help us understand the new update we have brought here, and it will also help us make improvements for the rest of the weekend in Malaysia. There is still a lot of work ahead of us, though. Red Bull seems to be the fastest both on a single fast lap and on long runs. McLaren and Ferrari are also competitive, especially at higher fuel loads. The track offered fairly little grip today, but conditions will probably improve by Saturday and Sunday. We will work hard tonight to find improvements and give our best in qualifying tomorrow afternoon.”
“Today we tried the latest update package on both cars. Instead of the hoped-for improvement in lap times, however, we struggled with a tricky setup and heavily overheating tires. In the first practice we had some components on the cars that may have distorted the situation. In the second practice, however, both cars were in a representative configuration and it looked as if we were still trailing, particularly behind Red Bull. We have some good ideas for setup changes that we want to investigate during the overnight simulator work. We will also analyse today's data further to understand why we are apparently lacking a bit of pace. We are optimistic that these analyses will bear fruit with such a new package. The top times are not particularly representative, and we should be able to improve our single-lap pace relatively easily. Our concern is more the long runs, where we had an unusually large pace deficit. That will be the harder problem to solve.”
Why this matters
The weekend marks Formula 1's first running at Sepang in nine years, so teams had no recent data for its aggressive asphalt and warm, humid conditions. Mercedes brought a new upgrade package and found itself behind Red Bull on both single-lap and long-run pace, a deficit it must address overnight before qualifying. Its drivers expect the low-grip track to improve by Saturday and Sunday.
