Red Bull Racing rookie Isack Hadjar was forced to retire from the 2026 Australian Grand Prix on Lap 12 after suffering a catastrophic power unit failure, ending what had been a highly promising start to his Formula 1 career. The Frenchman, who had qualified brilliantly and started from third on the grid, was running in fifth position when his RB21 began emitting heavy smoke between Turns 8 and 9 at Albert Park.
Hadjar Mechanical Failure: What Happened on Lap 12?

Video footage from the race broadcast clearly captured the moment Hadjar’s Red Bull lost power on the straight between Turn 8 and Turn 9. The car immediately dropped into neutral, with the engine going completely silent as thick smoke poured from the rear of the RB21. Hadjar allowed his stricken car to roll safely off the racing line, letting competitors Lindblad and Norris pass before the corner, before bringing it to a stop on the grass.
Mechanical analysis of the incident points strongly toward a hydraulic system failure as the primary cause. The sudden shift into neutral and the complete loss of engine power suggest a total hydraulic collapse, consistent with the volume of smoke seen escaping from the car. Red Bull Racing has not yet issued an official statement on the exact cause.
“Car Is Broken… Everything” – Hadjar’s Radio Message

In a radio message that immediately circulated on social media, Hadjar delivered a blunt assessment to his Red Bull engineers: “Car is broken… everything.” The message underlined the severity of the failure, which left the 20-year-old stranded trackside while the Australian Grand Prix continued around him.
Hadjar’s Impressive Start to His Formula 1 Career Disrupted
The retirement is a bitter blow for Hadjar, who had shown exceptional pace throughout the Australian Grand Prix weekend. The former Formula 2 champion delivered a standout qualifying performance to claim third on the grid, a result that raised expectations of a strong points finish or even a podium challenge in his early F1 appearances.
Running fifth at the time of his retirement and showing strong pace in race conditions, Hadjar had looked well-placed to score a significant points haul for Red Bull Racing before the power unit issue struck. The large crowd of spectators in the grandstands, many wearing Red Bull and McLaren colours, watched on as the promising race came to a premature end.
Red Bull Racing’s Reliability Concerns at Albert Park
Hadjar’s retirement adds to the reliability concerns that have periodically surrounded Red Bull Racing’s power unit programme. A failure of this nature at such an early stage of the race, particularly with a driver performing at a high level, will prompt a thorough investigation from the Milton Keynes-based team ahead of the next round of the 2026 Formula 1 World Championship.
Meanwhile, Max Verstappen continued the race in the second Red Bull, also battling through challenging conditions at Albert Park as the 2026 Formula 1 season gets underway.
