The incredible history of Christian Horner reveals how Max Verstappen’s mother gave up her F1 dream at the age of 21, even though she was in the “top 10 of the world”
The world of Formula 1 is one of unparalleled speed, precision and sacrifice, where dreams are often tested by the reality of life. Christian Horner, the iconic team boss of Red Bull Racing, recently shared a fascinating story that sheds light on the background of one of the greatest talents in sport: Max Verstappen. However, the story is not only about Max, but also about his mother, Sophie Kumpen, a woman whose own racing career forms a remarkable but little chapter in the history of motorsport. Her decision to give up her promising career at the age of 21, even though she was among the top 10 in the world, is a story of courage, sacrifice and love that forms the core of this article.

Sophie Kumpen was an exceptional talent in kartsport in the nineties, a discipline that often serves as a springboard to higher racing classes such as Formula 1. Her skills behind the wheel were unparalleled, and she was soon recognized as one of the most promising drivers of her generation. According to Horner, who was active in motorsport and Sophie personally at that time, she was not only good, but exceptional. “She was in the top 10 in the world,” he said in a recent interview, emphasizing how she regularly fighted with drivers who would later grow into legends. Her precision, speed and fearlessness made her a formidable opponent on the go -kart track, and many saw a future star in motorsport in her.
But the life of a driver is rarely simple. Kartsport, and motor sport in general, requires not only talent, but also financial resources, dedication and a network of support. For Sophie, the path to success was strewn with obstacles, not least because at that time motor sport was dominated even more strongly by men. Yet she was not discouraged. She continued to race, tighten her talent and establish her name in a world that offered little room for mistakes. Her dream to break through to Formula 1 seemed within reach, until life took a different turn.

At the age of 21, Sophie faced a choice that would change her life forever. At that time she was not only a driver, but also a young woman with personal ambitions and responsibilities. The arrival of her son, Max, became a turning point. Maternity brought new priorities, and Sophie decided to give up her racing career to focus on her family. This was not a slight decision. It meant leaving a dream she had fought for years, a dream that brought her to the top of kartsport. But it was clear to Sophie: her family came first.
Horner describes this choice as one of the most powerful examples of sacrifice he has seen in sport. “She had everything to become a big name,” he said, “but she chose to focus her energy and dedication on her son.” That choice turned out to be invaluable. Max Verstappen, raised with the stories and passion of his mother, inherited not only her talent, but also her determination. Sophie played a crucial role in his early career, from guiding his cart -adventures to offering emotional support while he climbed the Ladder of Autosport. Her knowledge of the sport and her own experiences as a driver gave Max a unique basis, a foundation that eventually brought him to the top of Formula 1.
The story of Sophie Kumpen is one of silent heroes. While Max Verstappen conquers the world with his unparalleled performance, he unconsciously carries the legacy of his mother. Her sacrifice, her talent and her love for sport live on in his success. Christian Horner’s Revelation about Sophie’s past reminds us that behind every champion there is a story of untrited sacrifices. For Sophie, giving up her dream was not an end, but a new beginning – a start that the world has given one of the greatest drivers of this generation.
