Hadjar finished the Australian Grand Prix without a classified result after completing only 12 laps, removing his chance to convert a strong weekend into a race finish. Sunday at 4: 08 p. m. ET a mechanical problem forced him to stop at the side of the track and end his race early.
Hadjar’s retirement prompted a Virtual Safety Car and car evacuation
The immediate consequence was a Virtual Safety Car while marshals evacuated his car at the side of the circuit. Race officials placed the track under the Virtual Safety Car after the stoppage; evacuation of the vehicle followed the on-track halt and interrupted live race running for teams and drivers.
Isack Hadjar had qualified third behind George Russell and Kimi Antonelli
Earlier in the weekend Isack Hadjar posted the third-fastest qualifying time, lining up behind the Mercedes drivers George Russell and Kimi Antonelli. That qualifying result left hadjar well positioned on the grid, but the weekend’s on-track promise did not translate into a completed race result after his early exit.
Mechanical problem remains unclear—engine or gearbox cited
The cause of the stoppage was described as a mechanical problem, with uncertainty over whether it involved the engine or the gearbox. Team descriptions left the specific component in question unresolved; the ambiguity meant teams could not immediately conclude what repairs or inspections would be required.
Next confirmed step: a post-race technical review is expected this evening at 6: 00 p. m. ET. If the review identifies a gearbox fault, the car will require more extensive repairs and parts checks before it can be raced again; if the issue is limited to the engine, crews may focus on power-unit diagnostics instead.
