Isack Hadjar’s 2026 F1 Australian GP ended in retirement after battery issues plagued his Red Bull debut race. The French driver started third after a strong qualifying performance but suffered problems from the formation lap onwards. Speaking in the print media pen after his retirement, Hadjar explained the battery drainage issues that compromised his race from the start.
George Russell won the race for Mercedes ahead of teammate Antonelli. Leclerc completed the podium in third for Ferrari. Hadjar’s retirement marked a disappointing end to what had promised to be a competitive showing in his first race as Max Verstappen’s teammate.
Hadjar on no power for the race start at the 2026 Australian GP
Hadjar described the frustration of his opening lap during the 2026 F1 Australian GP, explaining that a battery issue immediately compromised his race despite a strong start. He felt taking the lead was certain otherwise.
“The start was amazing, I mean, I started the race with no battery for the launch. I had a very good launch, I was taking the lead easily, so at least that’s a good point of the day, we had very good starts,” he stated.
However, the strong getaway was short-lived as the car suddenly lost electrical power. Just as Hadjar believed he was about to take the lead, the battery depleted completely, forcing him to spend the following laps attempting to recover energy. He would drop to 4th at the end of the opening lap.
“And once I thought, ‘oh, I’m going to take the lead’, no more power, that was great. And so you can imagine for a couple of laps I’m spending time to just recover.”
The situation continued to worsen as the engine began sounding abnormal, making it clear the race would not end well. He had been running in P5 before it gave up.
“Engine sounded terrible, so I knew I was not going to finish the race. So, yeah, it was just a shame, to be in the mix with, I think, Lewis.”
The battery issues also left Hadjar at a significant speed disadvantage throughout the race. When asked about battling with Arvid Lindblad, he explained how difficult it was to defend against a rival with far more power on the straights.
“It’s hard to fight someone who’s going 30kph faster than you in the straight. That was my only highlight of the day.”
Hadjar explains battery issue during the 2026 F1 Australian GP
Hadjar clarified the nature of the battery problem during the 2026 F1 Australian GP. The issue stemmed from scenario management rather than technical fault.
“No, it’s not a technical issue, it’s just that we need to do better to avoid this from happening. We didn’t manage to simulate it in the whole six days of testing, in free practice as well.”
Under F1’s new 2026 power unit regulations, roughly half of the car’s power comes from electrical energy. That energy must be carefully harvested and deployed through systems such as recharge and boost, meaning energy management plays a much bigger role in race performance.
The new regulations created race scenarios that testing and practice sessions had not replicated. Hadjar acknowledged the learning process involved: “So, honestly, it’s just new scenarios, you know, race scenarios are different. So, yeah, it’s a good experience at least.”
When asked about reliability concerns during the weekend, Hadjar noted Red Bull’s testing had gone smoothly. The race procedures proved more demanding than practice sessions at the 2026 Australian GP.
“We just had a very smooth weekend so far. In practice sessions, I think, on these young engines that are not as demanding as a race procedure, laps to the grid. Staying still, temperatures are going up and down, so it’s very difficult for the guys,” Hadjar stated.
Settling into Red Bull for the 2026 F1 season
Despite the disappointing result, Hadjar expressed satisfaction with his adaptation to Red Bull. The French driver felt comfortable through the 2026 Australian GP weekend. Qualifying P3 and running in P5 before his DNF was extremely encouraging considering the struggles of Pérez, Tsunoda and Lawson in that seat over the last couple of years.
“Honestly, I felt great out there, you know, just zero mistakes the whole weekend. I felt very comfortable and it’s a shame. I wish I could be still on track fighting for third, that would be fun,” he stated.
Critical of racing quality under F1 2026 regulations ahead of Sprint weekend
Questions arose about the quality of racing under the new 2026 regulations following qualifying concerns in Melbourne. Hadjar did not share optimistic views about how the racing looked during the 2026 F1 Australian GP.
“No. I don’t see how the racing is good. At least for me, when I’m seeing cars going by everywhere, I don’t see how that’s a step forward.”
With little time to reflect, the 2026 F1 grid now faces a quick turnaround to the China Sprint weekend. Hadjar acknowledged the challenge awaiting teams as they continue learning the behaviour of the new cars and power units.
“Yeah, it’s going to be…it’s going to be very tough. Not only for us, for everyone, but you guys are going to have fun. I’m going to try,” he stated.
Confidence from performance level throughout the Australian GP weekend
Despite the retirement, Hadjar took confidence from his pace relative to Verstappen during the 2026 F1 Australian GP weekend. He emphasized his capability to compete at Red Bull’s level.
“Yeah, of course that gives good confidence, but I never doubted that. I’m here to take those points, be on the podium, and today we didn’t. It’s early days,” he concluded.
