Sophie-Marie Kumpen, born on October 30, 1975, in Hasselt, Belgium, is widely recognised as the mother of four-time Formula 1 World Champion Max Verstappen. Beyond this prominent familial connection, Kumpen forged her own respected career in motorsport as a highly skilled kart and racing driver.
Her journey in racing saw her compete against and earn praise from several figures who would later become household names in Formula 1.
Kumpen’s racing prowess and dedication to the sport established her as a formidable competitor in her own right. Her achievements on the track highlight a significant, though often understated, legacy within the racing world.
Early life and motorsport roots
Sophie Kumpen was born into a family with strong ties to competitive sports and motorsport in Belgium. Her father, Robert Kumpen, served as the former chairman of the football club KRC Genk, indicating a background steeped in high-level competition.
Her uncle, Paul Kumpen, and cousin, Anthony Kumpen, were also active in rallying and racing, respectively, further cementing the family’s connection to motorsport. This environment naturally introduced Sophie to the world of racing at a young age.
A formidable karting career
Kumpen began her karting career at the age of 10 or 11, quickly demonstrating exceptional talent and a smooth, consistent driving style. She rapidly ascended through the ranks of European karting, a highly competitive discipline that served as a crucial stepping stone for many future professional drivers.
During her karting years, Kumpen competed against a remarkable roster of future Formula 1 drivers, including Jenson Button, Nick Heidfeld, Jarno Trulli, and Giancarlo Fisichella. Christian Horner, who would later become the Team Principal of Red Bull Racing, also raced against her in the 1989 Junior World Cup.
Her talent was widely acknowledged, with Horner describing her as “very good” and “top 10 in the world” in junior karting. Former F1 driver David Coulthard and team owner Eddie Jordan also noted her potential to reach Formula 1.
Kumpen’s karting career was marked by several significant victories and strong performances on the international stage. She secured two Belgian Championships, showcasing her dominance domestically.
Her most notable international triumph came in 1995 when she won the prestigious Andrea Margutti Trophy, beating several future F1 drivers. This victory solidified her reputation as one of the leading kart racers of her generation.

Transition, marriage, and initial retirement
Following her successful karting career, Sophie Kumpen progressed into touring car racing in the mid-1990s. However, her racing career took a different path after her marriage to Dutch Formula 1 driver Jos Verstappen in 1996.
She made the decision to retire from competitive racing that same year to focus on raising their children and supporting her husband’s Formula 1 career. Their first child, Max Verstappen, was born in September 1997, followed by their daughter Victoria in 1999.
The couple’s marriage lasted for 12 years before they separated in 2008. Despite the personal changes, Kumpen remained a dedicated mother, ensuring her children were supported in their own burgeoning motorsport interests.
Brief return and career-ending injury
After a hiatus from competitive motorsport, Sophie Kumpen made a brief return to racing in 2013. She participated in the Formido Swift Cup in the Netherlands, demonstrating her enduring passion for the sport.
Unfortunately, her comeback was cut short during the final races at Circuit Zandvoort. Kumpen suffered a significant crash that resulted in a fractured vertebra, an injury that ultimately led to the definitive end of her racing career at the age of 37.
Legacy and influence on Max Verstappen
Even after retiring from racing, Sophie Kumpen’s connection to motorsport remained strong, particularly through her children. She has since embarked on a career as a social worker at the OCMW in Maaseik, Belgium.
Her influence on Max Verstappen’s driving style is often highlighted, with Max himself acknowledging that he inherited her smooth technique and ability to set consistent lap times. This genetic and experiential transfer of skill underscores her profound impact on his career.
Kumpen continues to be a supportive presence in Max’s life, maintaining a unique ritual of lighting a candle for him before every Formula 1 race. This personal tradition reflects her deep care and continued involvement in his journey.
Sophie Kumpen’s own racing achievements, including her Belgian titles and the Andrea Margutti Trophy, firmly establish her as a talented and respected figure in motorsport. Her story is a sign of her individual skill and dedication, extending far beyond her role as Max Verstappen’s mother.
