The Red Bull Juniors finished fourth and seventh in the championship with Hadjar narrowly missing out on the FIA F3 title.
The Frenchman is delighted to be working with Red Bull and Hitech for another year and is hopeful he can take more victories this season.
“I’m really excited to be part of the Red Bull Junior team and continue this journey with Hitech for another year. Hopefully we can win some more races and have a strong season together,” said Hadjar.
The 18-year-old has enjoyed victories in multiple series across his career including French F4 and Formula 3.
Crawford, who took one victory for PREMA last season in Austria is equally pleased to be driving for Hitech but warned of FIA F3’s ultra competitive field.
“I am delighted to be back with Hitech for my first season of Formula 2. It will be a tough season with a strong grid but I am looking forward to what lies ahead,” said an elated Crawford.
The American joined in FIA F3 in last year after finishing third in the Euroformula Open Championship, taking eight wins in 2021.
Hitech Team Principal Oliver Oakes added: “We are excited to field once again two cars in FIA Formula 2 in Red Bull Junior Team colours, especially with two such promising young talents.
“Isack we saw first hand his last year as a rookie in Formula 3 and Jak we know him well from his first F3 season with us in 2021.”
The 14-round FIA F2 season will begin on the 3-5 of March in Bahrain and includes a first-ever trip to Albert Park in Australia.
