Czabok-Simpson Motorsport (CSM) is pleased to announce that New Zealand racing driver Madeline Stewart has signed a three-year agreement with the team, commencing with the 2026 season.
Stewart will compete with CSM in the IMSA Michelin Pilot Challenge Championship (GS class), driving a Porsche Cayman GT4 RS Clubsport, as part of a long-term program aimed at progressing into the IMSA WeatherTech SportsCar Championship by 2028.
The 2026 season will mark Czabok-Simpson Motorsport’s third year competing in the IMSA Michelin Pilot Challenge Championship, with the team continuing to build on its experience and technical foundation in the highly competitive GS category.
25-year-old Stewart has competed in the Porsche Carrera Cup North America Championship for the past two seasons and has spent the majority of her racing career within the Porsche racing pyramid.
She is also a member of the Porsche Mobil 1 Female Driver Program, underscoring her strong and ongoing relationship with the brand.
The three-year agreement reflects a shared commitment between Stewart and CSM that extends beyond on-track performance. The program is designed to support Stewart’s development as a professional driver, while also focusing on the commercial and strategic elements required for long-term success in North American sports car racing.
“This partnership with CSM represents a major step forward in my career,” said Madeline Stewart. “This multi-year deal allows us to build momentum with clear intent and work towards long-term goals together.
“Porsche has been fundamental to my racing journey, and continuing with the brand while joining a team entering its third season in the Michelin Pilot Challenge aligns perfectly with where I’m headed. I’m excited to grow with CSM on and off the track and to continue progressing within IMSA at the highest level.”
CSM co-owner Stephen Simpson emphasized the importance of the multi-year structure and Stewart’s alignment with the team’s future plans.
“Madeline brings proven Porsche experience, professionalism, and strong potential,” said Simpson. “Several of our current drivers are on long-term agreements. Madeline fits perfectly within our current driver roster and shares our long-term vision for where we want to progress in the future. This three-year commitment allows us to focus on development—both competitively and commercially—and to work toward a shared objective of stepping into the WeatherTech Championship together.”
As part of the agreement, Czabok-Simpson Motorsport will actively support Stewart’s commercial growth and career development, aligning partnership opportunities, brand strategy, and performance goals as the program progresses.
The 2026 season will represent the beginning of a new chapter for both Stewart and Czabok-Simpson Motorsport, built on continuity, ambition, and a clear pathway toward the top level of IMSA competition.
