Born in Cambridge, England, in 1998, Callum Ilott began his karting career at the age of seven.

Blisteringly fast on the track and approachable and likeable off it, Callum proved to be a natural racing talent as he racked up the honours, becoming British Karting Champion in 2011 and European Karting Champion in 2014.

Success in international karting, the FIA F3 European Championship, and the GP3 Series shaped Callum into a formidable competitor and led to his becoming vice champion in the 2020 FIA Formula 2 Championship. Taking five pole positions and six podiums, and winning three races as he finished second in the top tier of junior formula, Callum graduated to professional racing in fine form.

From 2019 to 2022, Callum served three different Formula 1 teams, working as an official F1 Test Driver for Ferrari, Haas F1 Team, and Alfa Romeo ORLEN, and as an F1 Reserve Driver at the latter. These roles included Free Practice 1 outings with two different teams, driving for Haas in FP1 at the 2020 Eifel Grand Prix, and with Alfa Romeo in the 2021 Portuguese and Austrian Grands Prix.

Callum secured a full-time race seat in IndyCar for 2022 with Juncos Hollinger Racing (JHR). Earmarked by some as a 'generational talent', this move allowed him to showcase his unique abilities in front of a worldwide audience, as he regularly put his one-car start-up team into the IndyCar top 10 in his rookie season.

Callum remained with JHR for his second season in IndyCar in 2023, securing two top-five finishes and helping Chevrolet win the Engine Manufacturers’ Championship. He also enjoyed a standout performance in the Indy 500 as he put the fledgling team into a 12th-place finish at the iconic annual event. Two seasons of IndyCar saw Callum become a more well-rounded driver, gaining experience racing on ovals, America’s unique street circuits, and road courses.

In addition to his IndyCar exploits, Callum secured a podium on his debut at the historic 24 Hours of Le Mans, finishing third with Iron Lynx in 2021 with teammates Matteo Cressoni and Rino Mastronardi in the GTE AM Class, further highlighting why Callum is so highly thought of among motorsport’s talent spotters.

Callum competed in 2024 in the #12 Hertz Team Jota Porsche 963 Hypercar in the FIA World Endurance Championship, alongside Norman Nato and Will Stevens. The highlight of the season was a stunning overall victory at the 6 hours of Spa securing.

2025 sees Callum reunited with Prema for the debut in the NTT Indycar Series.  An exciting chapter in Callum's career sees him return to Indycar for his third full season campaign as he looks to lead Prema to success on the Street Courses, Ovals and Road Courses across the USA in the super competitive Indycar Championship.
