Isack Hadjar is one of the most intriguing newcomers on the 2025 Formula 1 grid. Born in Paris to an Algerian family, the 20-year-old driver has risen through the Red Bull junior programme to earn a seat with Racing Bulls for his debut season, with a future at Red Bull Racing already confirmed. Yet despite his rapid ascent, many personal details about the young French-Algerian driver remain private or unconfirmed, making him a subject of growing curiosity among fans.
Hadjar’s path to F1 has been unusually swift. After joining the Red Bull Junior Team at age 17, he moved from Formula 3 to Formula 2 in consecutive years, finishing as runner-up in the 2024 F2 championship. That performance, combined with a winter reshuffle at Red Bull, earned him a promotion that few outsiders had predicted. His story is still taking shape, and several aspects of his biography remain open questions.

Who Are Isack Hadjar’s Parents and Family?
Isack Hadjar was born in Paris to an Algerian family. Both his father and mother have been noted in various sources, though the level of detail available about each differs considerably. Much of what is known comes from encyclopedic entries and team profiles rather than direct statements from the driver himself.
Who is Isack Hadjar’s father?
His father is Yassine Hadjar, a researcher in quantum mechanics and a physicist by training. According to biographical sources, Yassine also served as Isack’s mechanic during his early karting days, a hands-on involvement that helped launch his son’s racing career. The French Wikipedia entry and other encyclopedic references confirm this dual role as both a scientist and a supportive parent in the paddock.
Who is Isack Hadjar’s mother?
The identity of Hadjar’s mother is less consistently documented. French Wikipedia describes her as Lebanese-Algerian and a human resources director. A Portuguese-language entry, however, names her as Randa Hadjar and states she is a doctor who later transitioned into managing her son’s career and business affairs. No official source from F1 or Red Bull has confirmed either account, so these details should be treated as unverified at this stage.
Neither F1.com nor Red Bull Racing’s official driver profiles mention Hadjar’s mother by name or profession. This means that while multiple Wikipedia editions offer differing accounts, no primary team source has endorsed any of them. Readers should treat these details as unconfirmed.
