Porsche Motorsport North America and USAC Racing have confirmed the 2026 calendars for three single-make series that form key entry points to the Porsche Motorsport Pyramid in North America. Porsche Sprint Challenge North America by Yokohama will stage seven rounds, Porsche Sprint Challenge USA West by Yokohama will run six, and Porsche Endurance Challenge North America will contest four long-distance events. All Sprint Challenge weekends feature two races, while Endurance Challenge events retain the option for single drivers or co-drivers and include a mandatory pit stop window.
Sprint Challenge North America opens at Sebring International Raceway on March 6-8, then heads to Barber Motorsports Park on March 27-29 as an IndyCar support event. The schedule continues with Sonoma Raceway on April 10-12, Circuit of the Americas on May 7-9, Virginia International Raceway on June 19-21, Road America on August 7-9, and a season finale at Road Atlanta on September 11-13. The series groups drivers by machinery and remains a cornerstone of Porsche’s single-make sprint format in the region.
Sprint Challenge USA West begins at Apex Motor Club in Maricopa, Arizona, on February 6-8, then links up with the North American championship at Sonoma on April 10-12 and Circuit of the Americas on May 7-9. The West calendar returns to Sonoma on May 29-31 as the premier race series at Velocity Invitational, adds a summer stop at WeatherTech Raceway Laguna Seca with the date to be announced, and joins the North American field for a season finale at Road Atlanta on September 11-13. West events feature mixed-class racing with Porsche 911 GT3 Cup and 718 Cayman GT4 RS Clubsport entries competing together.
Porsche Endurance Challenge North America will again run four rounds alongside Sprint Challenge North America. The championship begins at Sebring on March 6-8, continues at Sonoma on April 10-12, resumes after an early summer break at Road America on August 7-9, and concludes at Road Atlanta on September 11-13. Like its sprint counterparts, the endurance series offers Pro and Pro-Am classes for 911 GT3 Cup and 718 Cayman GT4 RS Clubsport competitors.
“Our Porsche single-make schedules continue to stand out by offering a thoughtful balance of world-class tracks while keeping events and locations manageable for our teams and customers,” said Volker Holzmeyer, president and CEO of Porsche Motorsport North America. He noted that the mix includes stand-alone dates and appearances at established events with large crowds, reflecting customer feedback.
Beyond wheel-to-wheel racing, Porsche GT Track Day will return with four owner experiences running on Sprint Challenge weekends. Dates include Apex Motor Club on February 8, Sonoma Raceway on April 11, Circuit of the Americas on May 9, and Road Atlanta on September 13. Participants receive up to three hours of track time along with VIP hospitality and behind-the-scenes access.
Porsche reiterated that the calendar for Porsche Carrera Cup North America, the premier single-make series in the market, will be released later this year. As previously announced, Carrera Cup North America is among four global championships slated to debut the new Type 992.2 Porsche 911 Cup race car in its first season.
