SINGAPORE — Mercedes has confirmed its split-specification strategy for the Singapore Grand Prix sprint weekend, with Kimi Antonelli to run the controversial Malaysia upgrade package and George Russell reverting to the older aerodynamic specification at Marina Bay Street Circuit.
Team principal Toto Wolff had previously confirmed the team would run a drastic split-spec comparison test to troubleshoot its troubled aerodynamic updates, and photos from the paddock now show mechanics preparing two distinct floors side by side. Antonelli will keep the newer, potentially faster parts for the entire weekend as Mercedes looks to give him the best chance to extract pace and defend his championship lead on the tight street circuit, while Russell will take a complete step backward to the previous-spec package.
The allocation follows Russell's catastrophic power unit failure in the closing stages of the chaotic Sepang race. That mechanical DNF has left him saddled with a mandatory engine penalty in Singapore, which will send him to the back of the grid where overtaking is notoriously difficult and a podium fight on pure pace is effectively out of reach.
With the Sprint format allowing only a single 60-minute practice session before parc ferme rules lock the cars, Mercedes will use Russell's compromised weekend as a high-speed test. Running him as a comparative benchmark allows the factory to directly evaluate the failed Malaysia updates against the older spec without risking Antonelli's title challenge, a logical use of data gathering given George Russell's grid penalty after his Sepang retirement.
