Kimi Antonelli qualifies fourth for Sunday’s Singapore Grand Prix at Marina Bay, delivering Mercedes’ clearest sign yet that its recent upgrades are working after a split‑spec experiment across the weekend.

Mercedes debuted parts in Malaysia, but correlation doubts and a narrow window slowed progress. Singapore becomes the test bed, with Antonelli on updates and George Russell reverting to previous spec.

Early signs favor Russell. He takes second in Sprint qualifying as Antonelli manages seventh. Momentum flips when Russell crashes on lap one, while Antonelli finishes fourth with a clean run.

Overnight, Mercedes refines set‑up for the main session, improving rotation and traction. Antonelli responds with fourth in Singapore qualifying, while Russell is sixth before an engine penalty sends him rearward.

Antonelli says the car remains sensitive to driving approach and tyre preparation. Each set needs a tailored push to protect fronts without overloading rears under traction and Singapore’s heavy braking.

The split specification clarifies direction. The updated aero map appears effective once the balance window is centered, though it still demands ride‑height control and disciplined kerb usage to avoid spikes.

Strategy centers on track position. With Russell starting last, Mercedes can offset strategies, freeing Antonelli to cover leaders and exploit undercut windows on a circuit where overtaking remains difficult.

Race management should be less peaky than qualifying. That suits Antonelli, who expects longer phases to tame spikiness over the Marina Bay Street Circuit bumps and through traction‑limited exits.

Antonelli starts behind Max Verstappen, Charles Leclerc and Lewis Hamilton. A clean launch and undercut threat offer a podium chance, especially if Safety Cars compress the field around pit windows.

For Mercedes, Singapore strengthens confidence in its development path. The next steps focus on broadening the operating window and stabilizing performance across tyre sets, fuel loads, and track conditions.

If Sunday confirms qualifying gains, the team’s course correction becomes a waypoint in its season recovery. That would validate direction for Kimi Antonelli and accelerate Mercedes’ push toward lead fight.
