Mercedes Troubleshoots Aero Balance via Split-Spec Testing in Singapore

Mercedes opted for a split-specification approach during the Singapore Grand Prix to diagnose performance inconsistencies with their latest aero package. By reverting George Russell to a previous version, the team aimed to isolate issues that simulations and wind tunnel data failed to predict during the Bahrain Grand Prix in Malaysia.

Why it matters:

Aerodynamic balance is the deciding factor between a podium finish and a mid-field struggle. As the 2026 season reaches its climax, Mercedes must stabilize their platform to support Kimi Antonelli's championship bid and maximize the peak performance of their latest upgrades, ensuring the car is predictable across diverse circuit profiles.

The details:

• The Sepang Anomaly: Deputy Technical Director Simone Resta noted that Malaysia's unique tarmac and extreme temperatures masked the actual gains of the new floor, leading to a discrepancy between simulation and real-world performance.
• Balance Shift: While total downforce increased as intended, it was not delivered consistently across the chassis. This resulted in an overly aggressive front end, shifting the car's operating window and complicating driver consistency.
• Experimental Wing: Andrea Kimi Antonelli tested a new front wing during FP1. Due to having only one prototype, the team avoided using it in the race to eliminate the risk of a pitlane start following potential damage.
• Cost Cap Efficiency: Deputy Team Principal Bradley Lord highlighted that real-world split-testing is the most efficient way to gather data under current financial regulations, bypassing the need for costly additional components.

What's next:

All eyes now turn to the US Grand Prix in Austin. Mercedes expects to deploy the full updated configuration and the new front wing on both cars. For Antonelli, who recently claimed a podium in Singapore, these refinements are critical as he moves closer to clinching his maiden world title.
