Mercedes is rolling into Singapore with a mountain of questions to answer this weekend. As Motorsport.com Italia reports, the team's decision to split specifications between its two cars at Marina Bay is the clearest possible sign that something has gone wrong. Wind tunnel data had promised a three-tenths improvement, but reality turned those firm expectations into tangled doubts.
That evaluation work should ideally have happened on Friday at Sepang, but a sprint weekend format leaves little room for proper data gathering. Still, acquiring numbers to analyze during the upcoming break has become an absolute necessity. Speaking to the media on Thursday, George Russell pointed out that data gives no indication the new components are failing, while noting that even the older specification experienced competitive fluctuations. After all, the very same W17 that could have surrendered twenty seconds to McLaren at Budapest and Madrid went on to secure an eight-tenths qualifying advantage over rivals in Baku.
Andrea Kimi Antonelli is tasked with running the new parts, signaling that genuine potential and extra load remain hidden within the upgrades. Yet the effectiveness of these latest components is only the first mystery. The second concerns how the W17 handles a hot circuit packed with slow corners. Reviewing tracks featuring tight turns like Monaco, Canada, Austria, and Azerbaijan, the team has generally shown competitiveness, although conditions varied.
In Malaysia, the major headache stemmed precisely from a performance deficit in slow corners. Drivers complained of understeer from Friday onward, struggling to close the line and relying heavily on throttle application to rotate the machine. On an asphalt surface expected to feature severe degradation, this dynamic heavily punished the rear tires. While the new package might have shifted the balance, the primary suspicion points toward the brutal combination of abrasive asphalt and blistering heat.
Sepang presented the most abrasive surface of the entire season, creating a miserable cocktail that severely limited grip. When grip levels drop, time gained in grip-limited areas shrinks, putting maximum pressure on slow turns. Mercedes suffered throughout the weekend in those exact sections, whereas rivals like Red Bull found strong traction and exit speed. Although the W17 showed speed in faster sections where drivers felt the extra load of the new parts, it could not make up for the ground lost elsewhere.
Singapore features numerous ninety-degree corners, and even under night skies, bringing the front tires up to working temperature remains a delicate task. With high temperatures historically proving unfriendly to the Brackley machine across venues like Miami, Barcelona, and Hungary, the weekend ahead will test whether those slow corners can return to favoring the Silver Arrows.
