Isack Hadjar’s first Grand Prix weekend as a Red Bull Racing driver had the unmistakable feel of a statement being made — right up until the moment the power disappeared.
Hadjar had put the RB on the second row with an eye-catching third in qualifying on debut, then launched cleanly in Melbourne and immediately looked capable of turning the opening metres into something far more valuable than a headline. He’d jumped the Mercedes pair of George Russell and Kimi Antonelli well enough that he could already see the first corner as an opportunity, not a defensive chore.
And then it simply stopped.
Red Bull’s post-race work has traced Hadjar’s retirement back to a power unit failure, a particularly sore one given the context: 2026 is the first season the team has gone racing with its own engines, produced through its in-house Powertrains project. The investigation is continuing ahead of this weekend’s Chinese Grand Prix, and one key detail is still being worked through — what, if anything, can be salvaged from Hadjar’s allocated pool of components after the Melbourne failure.
That matters, because this isn’t just about a lost result. In the first race of a new rules cycle, reliability and component usage quickly become as defining as outright pace. A failure in round one doesn’t only remove points; it threatens to push a driver onto the back foot in terms of engine management and long-term planning, especially when the new package is still learning what race-weekend stress actually looks like.
Hadjar’s own description of the moment was brutally simple. One second he was talking himself into the lead, the next he had “no more power”.
“The start was amazing,” he said afterwards. “I started the race with no battery, so the launch was a very good launch. I was taking the lead easily… Once I thought, ‘Oh, I’m going to take the lead’, no more power.
“And so, you can imagine, for couple of laps I’m spending time to just recover. Engine sounded terrible, so I knew I was not going to finish the race. It’s a shame. I think I was going to be the mix with Lewis [Hamilton].”
There’s a nuance in there that’s easy to miss if you only skim the quotes: Hadjar’s “no battery” comment refers to the way Red Bull approached the start procedure, not the failure itself. Several drivers were caught out by power deployment and energy state on the grid in Melbourne — Max Verstappen included — but Hadjar was clear that what ended his race was separate.
“No, it’s not a technical issue,” he said of the battery situation. “We need to do better to avoid this from happening… honestly it’s just new scenarios. A race scenario is different. It’s good experience at least.
“When you do practice sessions with these young engines, they are not as demanding as a race procedure — laps to the grid, staying still, temperatures going up and down — so it’s very difficult for the guys.”
That’s the bit that will resonate inside Red Bull more than the public-facing disappointment. Pre-season testing and Friday running can flatter a new power unit. The real pain arrives when you add queuing in the pitlane, heat soak on the grid, stop-start procedures, and the messy variability of an actual race start — and suddenly the margins you thought you had evaporate.
It also put an uncomfortable spotlight on Red Bull’s opening weekend as a whole. Verstappen didn’t record a qualifying lap after crashing at Turn 1 on his first Q1 attempt, then salvaged sixth on Sunday — nearly a minute behind Russell’s winning Mercedes. Hadjar’s pace, then, was the brighter data point: a debutant placing the car third and feeling at home quickly enough to talk about mixing it with the front group. Red Bull got that promise for 10 laps, and then got the reminder of what new-era F1 can do to even the best-prepared operations.
Hadjar at least sounded like a driver who’d taken confidence from everything up to the failure. “Honestly, I felt great out there. Just zero mistakes all weekend. Very comfortable,” he said. “It’s a shame. I wish I could be still on track fighting for third.”
There was even time for a small, wry footnote: his only real on-track “highlight” was an early skirmish with Racing Bulls debutant Arvid Lindblad — though Hadjar noted it’s not much of a fight when the other car is “30kph faster” on the straight.
For Red Bull, though, the significance sits elsewhere. Melbourne wasn’t just a messy opener; it was a live stress test of the Powertrains era, and one of its two cars didn’t reach the finish. The team’s immediate task in Shanghai is obvious: pin down the failure, protect the component pool if it can, and prove quickly that what happened to Hadjar isn’t the start of a pattern.
Hadjar has already shown he can deliver the kind of clean, fast weekend Red Bull demands. Now the question is whether Red Bull’s newest, most consequential project can give him the uninterrupted racing he needs to turn that promise into points.
