Road To Le Mans

Sweden’s William Karlsson continues his ascent toward his ultimate ambition: the 24 Hours of Le Mans and the FIA World Endurance Championship.

Swedish racing talent William Karlsson reached a significant milestone this year as he made his debut in Road to Le Mans, the prestigious LMP3 event held during Le Mans week. As part of the Michelin Le Mans Cup, Road to Le Mans offers emerging drivers the rare opportunity to compete on the legendary Circuit de la Sarthe - the same stage where the 24 Hours of Le Mans takes place. For many, it is a defining step on the pathway to the highest ranks of endurance racing.

Competing with Inter Europol Competition, the team he has represented throughout the season, William seized the chance to showcase his speed and racecraft on motorsport’s most iconic circuit. The experience marked a major step forward in his journey toward his long-term goal: earning a place on the grid in the Hypercar category at the 24 Hours of Le Mans.

For William, driving at Le Mans was more than just a debut - it was a glimpse of the future he is working tirelessly to reach.

William Karlsson

William began his motorsport journey at just two years old, and started competing at the age of six, beginning in karting, where he steadily climbed through the ranks and became one of the top young drivers. After a highly successful karting career, he transitioned into formula cars. His debut season in 2020 resulted in a Swedish Championship bronze medal, followed by a breakthrough year in 2021, where he claimed both the Swedish Championship gold and the Nordic Championship title in Formula Nordic.

In the years that followed, William continued to broaden his international experience, racing in some of Europe’s most competitive junior categories. His career includes seasons in the Italian F4 Championship, Formula 3: Formula Regional by Alpine (FRECA), Formula 3: Eurocup-3, as well as GT4.

This year marked yet another important step as William made his debut in LMP3, beginning the endurance racing chapter of his career - one that is now guiding him steadily toward the world’s most prestigious endurance race: the 24 Hours of Le Mans.
