Madeline Stewart has signed a three-year contract with Czabok-Simpson Motorsport, which will see the Porsche Mobil 1 Female Driver Program member make her IMSA Michelin Pilot Challenge debut next year in one of the team’s Porsche 718 Cayman GT4 RS Clubsports.

The Kiwi’s deal with the Indianapolis-based outfit is aimed at progressing into the WeatherTech SportsCar Championship by 2028.

Stewart, 25, has competed in Porsche Carrera Cup North America for the past two seasons with JDX Racing and has spent the majority of her career within Porsche Motorsport’s pyramid, beginning with Porsche Sprint Challenge North America by Yokohama after moving Stateside in 2023.

Prior to that, she was part of Earl Bamber Motorsport’s Porsche Sprint Challenge Australia program.

“This partnership with CSM represents a major step forward in my career,” said 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 team co-owner Stephen Simpson added: “Madeline brings proven Porsche experience, professionalism, and strong potential.

“Several of our current drivers are on long term agreements [and] Madeline fits perfectly within our current driver raster and shares our long-term vision were 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, CSM will actively support Stewart’s commercial growth and career development, aligning partnerships opportunities, brand strategy, and performance goals as the program progresses.
