Mercedes has confirmed that its recent upgrade package introduced in Malaysia shifted the aerodynamic balance of the W17 too far forward, making the car significantly harder to drive despite increasing overall downforce. The team gained valuable data from the Singapore Grand Prix weekend, where split configurations and reopened parc ferme conditions allowed experimentation. Deputy technical director Simone Resta explained that while the upgrade delivered more downforce in high-speed sections, the gains were inconsistent across operating conditions, altering the car's balance and narrowing its optimal window.
This has forced changes in both set-up and driving technique, particularly affecting drivers who relied on the car's previously stable rear end. Andrea Kimi Antonelli, known for an aggressive corner-entry style, has had to adapt as the car became less forgiving outside its ideal window. Mercedes now aims to re-centre the car's operating window during the break ahead of Austin, acknowledging untapped potential in the new package but recognizing that accessing it consistently has become more complex.
The shift has exposed a trade-off: increased downforce at the cost of driveability, requiring a holistic approach to unlock performance.
