A Belgian karting prodigy who raced wheel-to-wheel against future Formula One champions, Sophie Kumpen won one of international karting’s most prestigious titles before stepping away from the sport at the height of her powers — a decision that helped set in motion one of the most remarkable dynasties in modern motorsports.

EARLY YEARS

Born on October 30, 1975, in Hasselt, Belgium, she grew up in a family already embedded in organized sport and motorsports culture [4]. Her father, Robert Kumpen, served as the former chairman of KRC Genk, the Belgian football club [4]. The motorsports influence came most directly from her uncle, Paul Kumpen — a former rally and racing driver who later co-owned Belgium’s largest bicycle manufacturer, Ridley Bikes, and founded PK Carsport [4][13]. Her cousin Anthony Kumpen would go on to win the NASCAR Whelen Euro Series championship in both 2014 and 2016 [13]. Racing, in other words, was not a departure from family tradition; it was the tradition.

Sophie started karting at around age eleven, and by the time she entered the Junior Karting World Championship in 1989, she was already competing against a young Christian Horner — future Red Bull Racing team principal and, in a twist the sport’s scriptwriters couldn’t have planned, the future boss of her son Max [21][27]. By 1991, at sixteen, she entered the FIA World Championship in Formula A, finishing ninth and placing ahead of a driver named Giancarlo Fisichella, who would eventually win three Formula One Grands Prix [21]. She went on to compete in multiple editions of the Karting World Championship between 1991 and 1994, with finishes ranging from ninth to twenty-sixth [4][21].

She learned Italian specifically while racing for the elite Italian team CRG, and ultimately became fluent in five languages: Dutch, German, English, French, and Italian [4]. That is not the biographical footnote it might appear to be — it reflects how embedded she was in the international karting circuit from a very young age, competing not as a curiosity but as a genuine contender in a world-level sport.

OTHER INTERESTS

Before karting took hold, she experimented with ballet — and recognized almost immediately that the regimented, graceful discipline was fundamentally at odds with her nature [21]. That self-awareness proved clarifying. Once she found karting, the choice of where to invest her competitive energy was settled. Away from racing, she went on to build a career as a social worker, eventually working at the OCMW in Maaseik, Belgium [4]. She has also maintained a steady, visible presence at Formula One Grands Prix as Max’s career has grown — less as a celebrity parent and more as someone who understands, from experience, exactly what her son is doing out there.

EARLY SUCCESS

Sophie won the Belgian Championship in Formula ICA in 1991 [4], establishing herself as the dominant karting talent within her home country. That same year she competed internationally in the Formula A World Championship and finished ninth — at sixteen years old, in a field that included drivers who would go on to race in Formula One [4][16]. She competed across Formula A, Formula K, and Formula Super A categories throughout the early 1990s, developing the breadth of technical understanding that comes from not specializing too narrowly too soon [1].

Her defining competitive moment came in 1995 at the Trofeo Andrea Margutti, held at the South Garda Karting Circuit in Lonato, Italy — one of international karting’s most prestigious annual events, named after a young driver who died in 1989 and first won, in 1990, by Giancarlo Fisichella [6]. Racing in the Formula A category for CRG, she won the trophy outright, becoming only the third woman in history at that point to win a major senior international karting title [4]. The two women who had preceded her were Susanna Raganelli and Cathy Muller [4]. Beitske Visser and Luna Fluxá would later join that cohort [4], but the list remains short by any measure.

During this period she was competing as a teammate to a young Jenson Button — later the 2009 Formula One World Champion — and the two were, by contemporary account, “really competitive, often racing against each other” [21]. She also raced against Jarno Trulli and Nick Heidfeld, both of whom built substantial Formula One careers [7]. The field she ran with, in short, was not a regional one.

Her transition toward car racing included competition in the Opel Lotus, but a crash during that period coincided with her marriage to Formula One driver Jos Verstappen in 1996 [4]. The wedding itself was characteristically understated: a secret ceremony in Hasselt on a Friday, with only ten guests [8]. The birth of their son Max in September 1997 effectively concluded her competitive career. She made one attempt at a comeback, entering the Formido Swift Cup at Circuit Zandvoort on October 12 and 13, 2013 [4][11] — but a severe crash during the final races resulted in a broken vertebra and ended her return permanently [4].

NOTABLE ACHIEVEMENTS

• 1989: Competed in the Junior Karting World Championship, racing against future Red Bull Racing team principal Christian Horner [27].
• 1991: Won the Belgian Championship in Formula ICA [4].
• 1991: Finished ninth in the FIA Formula A World Karting Championship, placing ahead of future Formula One race winner Giancarlo Fisichella [21].
• 1991–1994: Competed across multiple editions of the Karting World Championship in Formula A, Formula K, and Formula Super A categories [1][4].
• 1995: Won the Trofeo Andrea Margutti at the South Garda Karting Circuit in Lonato, Italy — one of only three women in history to have won a major senior international karting title at that point [4][6].

INSPIRATIONS

The primary influence on her entry into motorsports was her family environment — specifically her uncle Paul Kumpen’s background in rally racing and the broader culture of automotive competition that defined her upbringing in Hasselt [4][21]. She has not pointed to a specific racing driver as a formative idol in documented interviews. What she has described, instead, is a visceral, immediate response to speed itself: the first time she drove a kart, she recognized it as the thing she was built for [21]. That is its own kind of inspiration — less about who to emulate and more about what, finally, fits.

REPUTATION

Christian Horner — who raced against her at the 1989 Junior Karting World Championship and later became team principal of Red Bull Racing — has been unambiguous. Speaking on the Eff Won podcast, he said: “I raced in the 1989 Junior Karting Championship, and I raced against Max Verstappen’s mum. She was top 10 in the world at that point, she was fantastic.” When asked directly whether she beat him, Horner confirmed: “Yes she did.” [27] Sophie, for her part, has put it more succinctly. When asked about their competitive history, she told Horner: “He always drove behind!” [14]

Eddie Jordan and David Coulthard have both stated publicly that she possessed the potential to race in Formula One [1]. Those are not throwaway compliments from figures known for handing them out freely. Those who observed her racing consistently noted a “very fluid” driving style coupled with an ability to set “consistent times” — qualities she herself was told about throughout her competitive career [1]. Max Verstappen has credited his mother’s side of the family as the source of the real racing genes, saying: “My father competed in Formula 1, and my mother raced karts against drivers who eventually made it to F1 — names like Jenson Button and Giancarlo Fisichella. In all honesty, our real racing genes are on my mum’s side.” [5][24] He has also remarked of her career’s end: “That all changed when she got pregnant with me. In a way, I ended her career — all thanks to little old me.” [5][24]

Her pre-race ritual has become its own footnote in Formula One lore. Since a race in Barcelona in 2016, she has lit candles at the local church in her neighborhood before every one of Max’s races [15]. She has explained it plainly: “I have sort of a, not really a religion, but you burn a candle for something that has to go well.” [15] Before each race, she sends Max a photo of herself with the lit candle. His response has been characteristically direct: “Before every race, I receive a picture. There she is again with the candle. She always does that in the local church in her neighborhood. At some point, I said, quit sending it to me. It doesn’t matter, anyway.” [15] She has continued sending them regardless. Given that he has won four World Championships since 2016, the debate about efficacy remains, at minimum, unsettled.
