Isack Hadjar Criticized for Radio Outburst After Frustrating US Grand Prix

The Full Story

Isack Hadjar’s radio outburst during the United States Grand Prix in Austin has drawn sharp criticism from former Formula 1 driver Ralf Schumacher. The 22-year-old Red Bull driver, competing in his second F1 season, expressed intense frustration over technical issues that compromised his race, culminating in a sixth-place finish.

Hadjar started the race well, qualifying third on the grid, but immediately lost positions off the line due to a problematic start. He blamed Red Bull’s clutch system for the poor launch, describing it as “too fragile” and unable to handle the temperatures, a problem he said is beyond his control. His difficulties were compounded by radio communication failures during his pit stop, which led him to rejoin the track on the wrong engine map, further costing him time.

Speaking to Sky Sports F1 after the race, Hadjar was candid about his mounting frustration. “I do everything perfectly in terms of procedure, and then I just have clutch over delivery. These things are just out of my control. It’s starting to piss me off,” he said. He also called for a redesign of the clutch, emphasizing that the current system struggles under race conditions.

Hadjar’s blunt airing of grievances over team radio did not sit well with Schumacher, who voiced his disapproval on the Backstage Boxengasse podcast. Schumacher suggested that Hadjar’s behavior was inappropriate and that the former Red Bull advisor Helmut Marko, who is no longer with the team, would have intervened to curb such outbursts. “I wouldn’t exactly call it a lack of decency, but it is not behaviour that you should display in this way,” Schumacher said. He added that Hadjar now carries significant responsibility for the team and brand, and must learn to manage his frustrations more constructively.

The Red Bull team has faced repeated issues with starts this season, affecting both Hadjar and his teammate Max Verstappen. Verstappen himself finished third in Austin but also expressed frustration with the starts. Hadjar’s technical setbacks and radio problems highlight ongoing challenges for Red Bull’s race operations.

As the season progresses toward the Mexico City Grand Prix, attention will focus on whether Red Bull can address the clutch reliability and communication issues that have undermined Hadjar’s performances. The young driver’s ability to channel his frustration productively will also be under scrutiny as he continues to develop within the team.
