Caldwell spent 2021 competing in Formula 3, finishing eighth overall in the final standings - taking one win and scoring three podiums.

With two rounds of the F2 season to go in Saudi Arabia and Abu Dhabi, Caldwell will be looking to impress as he hopes to secure a drive for next season.

Caldwell will replace David Beckmann for the final two rounds of the campaign.

“I’m excited to join Campos for the last two rounds,” Caldwell said. “They’ve made good progression throughout the year so I’m really looking forward to working with them.

“I want to thank the team for the opportunity, I can’t wait to see what the car can do and gain experience ahead of my goal of a full season in Formula 2 next year.”

Campos Racing Sporting Director, Adrián Campos added: “I would like to extend a warm welcome to Olli (Caldwell) from Campos Racing. Olli is a driver who always awakened our interest and very recently he has played a key role in the FIA Formula 3 in which he performed excellently.

“Our goal is to help him to rapidly adapt to the Formula 2 car. We feel confident that joining Ralph, our driver line-up will be able to deliver strong performances and achieve top results during the last two rounds.”

On Tuesday, Campos announced that it will retain Ralph Boschung for next year.
