Mercedes to Run Split Aero Specs in Singapore for Direct Comparison
Mercedes has opted for a split-specification strategy for the Singapore Grand Prix, fielding two different aero packages on their W17s. While Kimi Antonelli will continue with the latest updates, George Russell is reverting to a previous version to provide a definitive back-to-back comparison over the Sprint weekend.
Why it matters:
The team is struggling to decipher whether their recent upgrades—introduced in Malaysia—actually offer a legitimate performance gain. Because the data from Sepang was inconclusive, this direct comparison is the only way to determine if the new parts are a step forward or if they should be abandoned in favor of the previous baseline.
The details:
- The Split: Kimi Antonelli will run the updated package, now complemented by a new front wing, to test its efficacy in Singapore's characteristic low-speed corners.
- The Baseline: George Russell will utilize the specification that secured victory in Baku. Since Russell is already facing a power unit grid penalty, the team viewed this as the perfect opportunity to run the older, proven baseline without further compromising his starting position.
- The Malaysia Outlier: Both drivers believe the Sepang results were skewed by extreme conditions, including 60-degree track temperatures and rough asphalt, which likely masked the new package's true potential.
- Performance Delta: Russell highlighted that fluctuations in lap time can be as high as one second even with consistent cars, making a direct side-by-side test essential to filter out external variables.
What's next:
The data gathered this weekend will be pivotal for Mercedes' late-season development. If Antonelli’s updated W17 outperforms the baseline in the low-speed sectors of Singapore, the team will likely commit fully to the new direction. Otherwise, they may pivot back to the Baku-spec configuration for the remaining races of the 2026 calendar.
