Early passion.
Natural ability.

Henry Joslyn’s love for racing took hold early. At just 8 years old, he climbed into a Honda Cadet kart at Shenington Kart Circuit — and something clicked. What started as a test quickly became a passion, with flashes of natural speed that hinted at a bright future ahead.

Henry is a British racing driver competing internationally in GT racing, building his career within the European GT4 Championship with Gazoo Racing Sweden.

He began his racing journey in karting at the age of eight, quickly establishing himself as a front running driver at both national and international level. In 2022, he became the IAME Euro Series X30 Junior Vice Champion and the youngest ever winner of a British Championship Junior round, competing against drivers up to three years older.

Transitioning to cars in 2023, Henry adapted quickly to the Ginetta Junior Championship, securing multiple race wins, podiums and fastest laps across two seasons, finishing fourth overall in 2024.

In 2025, Henry moved into single seaters in British Formula 4, where he immediately demonstrated front running pace. He secured a double pole position on his debut weekend and went on to achieve five pole positions and seven podiums across the season.

Now focused on international GT racing, Henry is developing within multi manufacturer competition as part of a long term pathway towards professional GT and endurance racing at the highest level.
