Isack Hadjar endures a bruising Saturday in Singapore. After a power unit change and suspected gearbox failure, he sets no time in qualifying and starts from the back.

A sprint power unit failure ends his RB22’s run behind the safety car, forcing retirement and triggering a rapid turnaround between sessions.

Red Bull fits a replacement power unit before qualifying, allowing Hadjar to rejoin. He thanks the mechanics over the radio as the car returns to the track.

The respite proves brief. He stops on track, restarts, reaches the garage, then reports renewed issues on his next run: “Same issue, I’ve lost the gears!”

The team withdraws the RB22 from qualifying. Team principal Laurent Mekies says the stoppage is unrelated to driver error and suspects a gearbox fault under investigation.

The pattern dovetails with recent scrutiny of his shifting systems, discussed in the Isack Hadjar F1 gear ban, as Red Bull prioritizes root-cause analysis before turning attention to race execution.

From a reliability standpoint, the double hit—power unit then gearbox—compromises mileage, validation of set-up changes, and tyre preparation on a track where rhythm usually dictates qualifying performance.

Strategically, a back-row start at Marina Bay demands patience, undercuts where possible, and safety-car opportunism. Hadjar’s first-lap approach becomes pivotal to avoid early turbulence.

The team’s swift power unit change highlights strong garage execution. But repeat stoppages suggest an intermittent systems or hardware issue that risks cascading failures if not isolated promptly.

Mekies indicates further checks will continue overnight. Resolution before Sunday is essential, with only a handful of 2026 rounds remaining and every incremental point influencing the constructors’ picture.

Hadjar’s race outlook hinges on clean air management, battery deployment, and caution-free stints. Post‑Singapore, Red Bull must bulletproof the gearbox package to prevent repeat failures across upcoming events.
