Mercedes AMG Petronas has adopted a split-spec strategy for the 2026 Singapore Grand Prix, running two different versions of their W17 car with drivers George Russell and Kimi Antonelli. This approach follows a major upgrade introduced at the Malaysia Grand Prix, which marked the team’s first significant update in four months but did not deliver the expected performance improvements.
At Singapore, Russell used the older specification last seen in Azerbaijan, while Antonelli piloted the upgraded W17 featuring a new front wing. Russell’s performance in both Free Practice 1 and Sprint Qualifying outpaced Antonelli’s, with the British driver qualifying five positions ahead. Despite this, Toto Wolff, Executive Director of Mercedes AMG Petronas, described the upgraded car as “a little more tricky to drive” but not necessarily slower, highlighting the need for further understanding and fine-tuning.
The split-spec strategy represents a compromise aimed at gathering valuable data to guide development for the 2027 season. Wolff acknowledged the risks involved in committing heavily to one large upgrade package, suggesting that future updates might be introduced in smaller increments to allow for easier adjustments. Currently, Mercedes leads the Teams’ Championship by 151 points over Ferrari, although their rivals have narrowed the gap with multiple race wins this season.
George Russell expressed confidence in the older spec car’s performance, which he found more manageable on track. Meanwhile, Kimi Antonelli admitted that he needed to improve his driving to extract more from the upgraded car and hoped for better results moving forward. The differing feedback from the two drivers underlines the challenges Mercedes faces in optimizing the new package.
Mercedes’ decision to run split specifications is a tactical move to balance performance and development insight amid a competitive field that includes Ferrari, McLaren, and Red Bull Racing. The team’s cautious approach reflects the complexities of managing upgrades within the evolving technical and sporting regulations of the championship.
Wolff’s comments emphasize that while the upgraded W17 has potential, it requires further refinement to unlock its full capabilities. The team’s focus remains on understanding the car’s behavior and making incremental improvements rather than relying on a single large upgrade to shift performance dramatically.
This strategy highlights the ongoing technical challenges teams face in Formula 1® as they strive to maintain competitiveness throughout the season. Mercedes’ split-spec approach at Singapore offers a clear example of how teams are adapting their development paths to balance immediate results with longer-term progress.
