Mercedes Splits Car Specs for Singapore GP to Diagnose Upgrade Failure

Mercedes is adopting an unusual strategy for the Singapore GP Sprint weekend, splitting the aerodynamic specifications between George Russell and Kimi Antonelli. The decision comes after a disappointing weekend in Malaysia, where the team's first major upgrade since May failed to yield expected gains, allowing Max Verstappen to dominate the event.

Why it matters:

Mercedes must urgently determine if their recent performance dip was a result of Malaysia's specific track conditions or a fundamental flaw in the new aero package. With the championship battle reaching a critical phase, resolving these inconsistencies is essential to maintain their competitive edge against Red Bull.

The Details:

• Split Specifications: George Russell will revert to the Baku-specification W17, while Kimi Antonelli will continue with the newer package introduced at Sepang.
• Front Wing Integration: Antonelli’s car will feature a new front wing that was missing from the Malaysia package. The team believes this component is key to unlocking the updated package's actual potential.
• Strategic Timing: The split was deemed a "no-brainer" because Russell will already start Sunday's main race from the back of the grid due to an engine penalty, minimizing the risk of using the older spec.
• Power Unit Status: The anticipated ADUO (Additional Development and Upgrade Opportunities) upgrade will not be deployed in Singapore; it is now expected for a later race, likely the United States GP.

What's next:

Mercedes will use the Sprint event as a live laboratory to compare the proven Baku spec against the updated W17. While Antonelli aims to extract maximum potential from the new parts, Russell plans an "all-out attack" to salvage a strong result despite his impending grid penalty. The findings from this weekend will dictate the team's technical direction for the final seven races of the 2026 season.
