Isack Hadjar has made a striking start to his F1 career, having joined the grid with the Racing Bulls team, after finishing runner-up in the 2024 F2 championship.
The Red Bull Junior driver impressed in his second year of Formula 2 in 2024, as he won feature races in Melbourne, Imola, Silverstone and Spa-Francorchamps and took the title down to the wire, finally missing out to Gabriel Bortoleto by 22.5 points.
Hadjar, 20, has largely continued that impressive form in 2025, despite being new to the Formula 1 grid. He started eleventh on the grid for his debut race at the Australian Grand Prix, and only just missed out on a top ten grid slot in qualifying. However, an error on the wet parade lap saw Hadjar spin off and out of the race before it had even begun. He stepped from the car, clearly in tears.
Hadjar was back on form for the second round in China, qualifying seventh ahead of team-mate Yuki Tsunoda. He was on course for a points finish before being called in for an extra pitstop by his team, which turned out to be the wrong strategic call.
Even so, his pace so far has attracted favourable comparisons to the struggling Liam Lawson at Red Bull.
Hadjar was favourite to get the spare seat at Red Bull’s junior team for 2025, having had several free practice outings for both Red Bull and RB — as it was named for the 2024 season — and completed post-season testing for the latter outfit at the end of the 2024 season in Abu Dhabi – outpacing Yuki Tsunoda‘s best time in identical machinery.
Both Red Bull team boss Christian Horner and advisor Helmut Marko spoke highly of Hadjar, with the former highlighting the promising rookie as ‘next in line’ for an F1 seat. That came sooner than expected, with RB driver Liam Lawson taking Sergio Perez‘s seat at Red Bull.
“We’re excited to have Isack with us next year, bringing a new and fresh dynamic to the team alongside Yuki in 2025,” said Laurent Mekies, Racing Bulls team principal. “His journey to Formula 1 has been nothing short of outstanding, he has shown remarkable growth, with a series of impressive results in the junior single-seater ranks. He has the talent and drive necessary to compete at the highest level, and we have every confidence that he will adapt quickly and make a significant impact.”
Hadjar described the announcement as a dream come true. “The journey from karting through the ranks in single-seaters, to now being in Formula 1 is the moment I’ve been working towards my whole life,” he said. ” I feel like I’m stepping into a whole new universe, driving a much faster car and racing with the best drivers in the world. It’ll be a huge learning curve, but I’m ready to work hard and do the best I can for the team.”

Like many on the current F1 grid, Hadjar began his career in karting – long recognised as the traditional starting point for aspiring racers.
“I was always interested in cars but not particularly the racing, because of the movie Cars,” the Frenchman told RedBull.com. “My grandparents and parents are mainly doctors or physicists so they have nothing to do with motor sport but my dad always watched F1, that’s it really.
“When I grew up I wanted to do go-karts as I started watching F1 at the age of 6 so my parents bought me one when I was 7! This love for racing just came by myself.”
Hadjar entered his first kart race in September 2012 and won, sparking a journey up through the motor sport rankings. He spent two years contending the French National Karting Championship and then made the leap to single-seaters in 2019.

Hadjar moved to French F4 championship and competed in his first race at Circuit de Nogaro in April 2019. There, he finished eighth on debut and soon followed that performance with two more top-six finishes at Pau.
