Millie Hart is a British racer who made a stunning transition from karting to car racing, securing the Nankang Tyre BMW Supercup Championship title in her first full season of circuit racing in 2025.

EARLY YEARS

Hart was immersed in motorsport from a young age, cutting her teeth in the competitive world of UK karting. She progressed through the ranks of the UK Ultimate Karting Championship with backing from Hansford Sensors, building the foundation that would eventually lead her to four wheels. Her karting career included a notable appearance at the Daniel Ricciardo Karting Series—founded by the F1 driver himself—where she finished 18th out of 32 competitors and second rookie, proving she could hold her own in mixed-gender competition.

EARLY SUCCESS

Hart’s circuit racing career began at the end of 2024 when she made her car racing debut at the BRSCC Evolution Trophy at Brands Hatch. Racing a BMW 1 Series with 230bhp and rear-wheel drive, she secured a class victory in race one under extremely wet conditions—a gutsy performance that immediately announced her arrival. On lap two, she posted the third-fastest time on track, showing remarkable confidence for someone making their debut in a car. That smart, composed driving in treacherous conditions laid the groundwork for what would become a dominant 2025 season.

REPUTATION

Hart earned a reputation as a fierce competitor who excels in mixed conditions and brings smart, measured aggression to the track. Her dominance throughout the 2025 BMW Supercup season was characterized by consistent scoring and an ability to control races from the front. At Snetterton, she looked “untouchable” after qualifying well over a second faster than her nearest rival—the kind of gap that makes competitors wince. She retained her championship lead through strategic podium finishes at Croft and was given a lifeline at Silverstone when rival Simon Waterfall faltered, ultimately sealing the title with a fifth-place finish that was all she needed. Her ability to complete every lap of the season while scoring two victories showcased the kind of reliability and racecraft that wins championships.

FUTURE GOALS/PLANS

Hart has made it clear she’s not satisfied with one championship. Her goal is to be a front-runner for the majority—if not the entirety—of future seasons. After making a superb impression throughout 2025, she’s looking to make further progress as she continues climbing the motorsport ladder. The next logical step would be a move into more competitive European racing series, where she can test herself against a broader field and continue building her reputation beyond the UK circuit.
