Niels Koolen Bio
Niels Koolen (born 25 May 2001) is a Dutch racing driver who currently competes in the 2025 Indy NXT series with Chip Ganassi Racing. A former competitor in the European Le Mans Series with Duqueine Team, Koolen has built a career that spans karting, junior single-seaters, Formula 2, and endurance racing. He is the son of rally raid driver and businessman Kees Koolen.
Early Life and Background
Niels Koolen was born on 25 May 2001 in Vorden, Gelderland, Netherlands. He grew up in a family with deep ties to motorsport, as the son of Kees Koolen, a rally raid driver and businessman. This family connection gave him early insight into the demands and rewards of professional racing, even though he did not begin car racing until his early twenties.
Like many future drivers, Koolen spent his formative years in karting, building the reflexes and race craft that would later support his move into single-seaters. The COVID-19 pandemic disrupted his plans, delaying his transition to car racing and leaving him as a relative latecomer to the junior open-wheel ladder. He has since credited that delayed start with a sharper focus once opportunities finally arrived.
Path to NASCAR
Koolen’s career path has run through European and American open-wheel racing rather than the NASCAR ladder system. He does not currently compete in the NASCAR Cup Series, NASCAR Xfinity Series, or NASCAR Craftsman Truck Series, and public information about any NASCAR program is not available. His progression through Formula 4, Formula Regional, Formula 2, and Indy NXT reflects a traditional open-wheel route shaped by his late entry into car racing and his family’s rally raid background.
Niels Koolen Career
Early Career (2022)
Koolen made his car racing debut in 2022, entering Round 6 of the F4 Spanish Championship with Monlau Motorsport. He also contested the final two rounds of the 2022 Italian F4 Championship with the same team, racing under a Belgian license. These appearances marked his first sustained test in single-seater competition after years in karting.
Competing in the Spanish and Italian Formula 4 championships gave Koolen valuable seat time and exposure to professional weekend formats. The campaign served as a learning year, allowing him to adjust to car racing at an age when many of his peers already had several seasons of single-seater experience.
Formula Regional and Eurocup-3 (2023)
In January 2023, Koolen was confirmed for the 2023 Formula Regional Middle East Championship with VAR-Pinnacle Motorsport. He then signed with Van Amersfoort Racing for the 2023 Formula Regional European Championship, lining up alongside Joshua Dufek and Kas Haverkort. The season was difficult, and he ended the standings in 37th place with a best finish of 19th, often trailing his teammates in pace.
Koolen also joined two rounds of the 2023 Eurocup-3 series at Jerez and Estoril. He was unable to score points in either round, using the outings to gather additional track time and prepare for the next step in the junior ladder.
Formula 2 and Endurance Racing (2024)
Koolen’s 2024 season began with a move to Indy NXT, where he signed with HMD Motorsports. His best result that year was a 10th-place finish on the Indianapolis Motor Speedway road course during the opening event, a performance that established a baseline for his adaptation to American open-wheel racing.
In August 2024, AIX Racing drafted Koolen into the FIA Formula 2 Championship after Taylor Barnard left the seat. He raced for the team at the Monza and Baku rounds alongside Joshua Dürksen, finishing 19th in both the Monza sprint and feature races. AIX Racing later confirmed that he would not return for the final two weekends of the season. Alongside his single-seater commitments, Koolen made his endurance racing debut in the 2024 European Le Mans Series with Duqueine Team, adding sports car experience to his resume.
Chip Ganassi Racing Era (2025–Present)
For the 2025 Indy NXT season, Chip Ganassi Racing signed Koolen to contest the full championship, marking his second year in the category. The move to one of the most established teams in the American open-wheel ladder signaled a clear step up in equipment and support.
Koolen finished the 2025 Indy NXT season eighth in the points standings, with a best result of fifth at Iowa Speedway. The campaign showed consistent improvement and positioned him as a developing talent within the Chip Ganassi Racing driver development pipeline.
Driving Style and Strengths
Koolen’s racing background includes both sprint and endurance formats, with experience in single-seaters and sports car machinery. His European Le Mans Series work with Duqueine Team suggested an ability to manage tire and fuel economy over long stints, while his Indy NXT results highlighted growing comfort on ovals and road courses alike.
Notable Races and Milestones
Among his career highlights, Koolen’s 10th-place finish in his Indy NXT debut on the Indianapolis Motor Speedway road course in 2024 stands out as an early marker. His fifth-place run at Iowa Speedway in 2025 with Chip Ganassi Racing represented his best Indy NXT result to date, while his Formula 2 outings at Monza gave him brief exposure to a series that feeds directly into Formula 1.

Indy NXT Highlights
Koolen’s Indy NXT career began in 2024 with HMD Motorsports, where a 10th-place finish on the Indianapolis Motor Speedway road course was his best result of the year. In 2025, he moved to Chip Ganassi Racing and improved to a best finish of fifth at Iowa Speedway, ending the season eighth in the overall standings.
Other Wins and Performances
Outside of Indy NXT, Koolen has sampled Formula 2 with AIX Racing, finishing 19th in both Monza races, and made his endurance racing debut in the 2024 European Le Mans Series with Duqueine Team.

Niels Koolen Family
Family Background and Racing Lineage
Niels Koolen is the son of Kees Koolen, a rally raid driver and businessman. His father’s background in long-distance off-road motorsport provided an early link to professional racing, even though Niels ultimately focused on circuit-based open-wheel and endurance formats.
Personal Life
Born in Vorden, Gelderland, Netherlands, Niels Koolen has built his career largely in Europe and the United States. Public information about his spouse, children, and detailed personal arrangements is limited, and no additional verified personal details are available.
2025 Season Performance
The 2025 season marked Niels Koolen’s second year in Indy NXT and his first full campaign with Chip Ganassi Racing. Driving the No. 10 entry, he showed steady progress across ovals and road courses, adapting to the team’s technical approach and race strategy. His season-best result of fifth at Iowa Speedway was the clearest sign of his growing pace within the series.
Koolen closed the year eighth in the Indy NXT points standings, a result that reflected consistent point-scoring finishes rather than a single breakthrough weekend. Working with Chip Ganassi Racing gave him access to a deeper engineering group and a more structured development plan than he had in his rookie season.
Looking ahead, the 2025 campaign positioned Koolen as a developing name within the Chip Ganassi Racing driver development structure. Continued improvement in qualifying pace and oval-race execution are likely to shape his outlook as he targets a step up the American open-wheel ladder.
