Mercedes to split garage specs at Singapore after Malaysia upgrade disaster

Mercedes arrives at the Marina Bay Street Circuit for the Singapore Grand Prix Sprint weekend in crisis mode, planning to run two separate aerodynamic specifications across its garage after a high-profile upgrade package introduced at the Malaysian Grand Prix produced a sharp and unexplained drop in performance.

Rather than committing to the new parts or abandoning them outright, team principal Toto Wolff has ordered a direct on-track comparison: one car will carry the older, previous-specification aero package while the other retains the new upgrades. The split is a frank admission that the team cannot yet explain what went wrong in Sepang.

“Malaysia was obviously a very difficult weekend for us,” Wolff said ahead of the Singapore round. “We have spent the days since then working hard to understand why our performance was not where it should have been.”

The exercise carries significant risk given the format of the weekend. Sprint events allow only a single 60-minute practice session before parc ferme conditions lock the cars, meaning Mercedes is sacrificing its sole set-up window to run what amounts to a live diagnostic test. There is no second chance to correct course before qualifying.

Wolff acknowledged the team is operating without clear answers. “We have identified several areas we need to investigate further, but F1 doesn’t offer simple answers, and we need more evidence before drawing firm conclusions,” he explained.

The team believes the tight, low-speed characteristics of Marina Bay will help isolate the problem. Singapore’s street circuit is aerodynamically and mechanically distinct from the abrasive Sepang surface, and Wolff hopes that contrast will finally reveal the flaw in the new package.

“Singapore gives us an immediate opportunity to continue that work,” he said. “The characteristics of the circuit are very different, and that will help us build a clearer picture of where we are.”

The split-specification approach is unusual at this level of the sport, where every practice lap is typically devoted to optimising a single, agreed configuration. That Mercedes is willing to forgo that optimisation underlines just how little confidence the team currently has in its own data following the Malaysian setback.
