Inside Mercedes’ Struggle: What Went Wrong at Bahrain GP
Highlights
- Mercedes introduced revised floor and sidepod updates in Sepang.
- Car performed better in high-speed corners but struggled in slow corners.
- George Russell retired due to a powertrain mechanical failure.
- Sepang’s rough surface caused tyre overheating and aerodynamic turbulence.
- Mercedes will analyze data ahead of the Singapore Grand Prix.
- Team aims to fix powertrain issues and improve car balance.
Mercedes end a bruising Sepang return, despite a revised floor and sidepods, as George Russell retires from a likely podium with a powertrain failure and slow-speed balance issues persist.
The package targets a wider operating window, but a nine-year gap since the last Sepang race complicates correlation and baseline understanding.
Headline speed looks competitive, yet time bleeds away in traction zones and hairpins. Russell’s retirement removes Mercedes’ best result of the weekend.
The updated floor generates good load in fast corners, but low-speed grip and stability trail expectations. Drivers need unusual inputs to rotate the car, Bradley Lord admits.
High track temperatures and an abrasive surface intensify tyre management. The Sepang circuit’s rough surface amplifies sliding and complicates pressures and camber targets.
Russell retires with a mechanical powertrain failure while running on a podium trajectory.
Uneven asphalt increases carcass flex, generating heat through repeated deformation. Overheating trims peak grip, shortens stints, and forces drivers to back off to protect the compound.
Roughness also perturbs underfloor airflow. As Andrea Stella notes, once the accelerated stream loses smoothness, turbulence erodes downforce consistency and harms balance through longer braking and rotation phases.
The floor update works in high-speed but exposes slow-speed rotation and traction weaknesses.
Those effects are hard to predict. Wind tunnels and CFD cannot fully replicate Sepang’s texture, so correlation work dominates practice and narrows the window for strategy experiments.
Reliability compounds the setback. Mercedes confirms Russell’s retirement stems from a mechanical power unit failure, costing around 15 points while analysis continues.
The team now prepares for the Singapore Grand Prix, where slow-speed demand is severe but the smoother surface should give clearer readouts on the package.
Focus areas include improving entry stability, traction on long-throttle exits, and broadening the usable balance window. That dovetails with ongoing work on the car’s balance direction.
Correlation between track data and simulation remains the priority before setup and mapping changes are locked.
Under current F1 rules on cost cap and ATR limits, Mercedes must prioritise reliability fixes alongside performance, or risk compounding points losses in a tight midfield.
The upgrade is not a dead end. Early signs suggest genuine high-speed gains, but extracting low-speed performance and restoring robustness decide whether the package becomes a net step.
